For each module, reference may be made to the above-mentioned descriptions in FIG. 2 and FIG. 3 , and details will not be repeated. The low temperature charging method may include but not limited to the following steps:

S401: The electronic device acquires first information through a logic control module.

The first information may include one or more of ambient temperature, screen status and charging information. The data acquisition module of the logic control module can collect the ambient temperature from the ambient temperature sensor, collect (via display driver) the display screen status, and collect charging information of the battery module. Wherein, the charging information may include one or more of battery temperature, charging port temperature, battery power, charger type and charging port type, battery current, and the like. For the specific acquisition process of the first information, reference may be made to the relevant description in FIG. 3 , and details are not repeated.

In a possible implementation manner, the first information may include ambient temperature, screen status, and charging information. The electronic device may acquire the ambient temperature periodically (for example, every 10 minutes), and acquire the screen status and charging information only when the ambient temperature is less than (or less than or equal to) the environmental threshold temperature. Under the condition that the ambient temperature information is greater than or equal to (or greater than) the ambient threshold temperature, there is no need to obtain other first information (ie, screen status and charging information). At this time, obtaining the screen status and charging information needs to satisfy the condition that the temperature is lower than the ambient threshold temperature to ensure the necessity of the obtained information, which can save processing resources and improve processing accuracy. In addition, periodically obtaining the ambient temperature can ensure the timeliness of obtaining the ambient temperature.

Wherein, the logic control module may store the ambient threshold temperature.

S402: In the case that heating has not been performed, the electronic device judges whether the first temperature-raising charging condition is satisfied based on the first information through the logic control module. If the first temperature-raising charging condition is met, execute S403; if the first temperature-raising charging condition is not satisfied, do not execute.

After the data acquisition module of the logic control module acquires the first information, it can send the first information to its temperature increase decision module. The temperature rise decision module can judge whether the first information meets the first temperature rise charging condition. When the first temperature-raising charging condition is met, the temperature-raising decision-making module of the logic control module determines the temperature-raising and generates first decision information. If the first temperature-rising charging condition is not satisfied, the temperature-rising decision-making module of the logic control module does not process and does not generate decision-making information.

In a possible implementation, when the first information includes ambient temperature, screen status, and charging information, the first warm-up charging condition may include charger access, the screen status is off, and the battery power is within a preset power range , the charging type is the preset charging type, the condition that the ambient temperature is less than the ambient threshold temperature, the condition that the battery current is less than the charging threshold current, the difference between the battery temperature and the charging port temperature, and the condition that the battery temperature is in the preset range, etc. one or more conditions.

It should be noted that the first information often corresponds to the first temperature-rising charging condition, and the first temperature-rising charging condition will be judged only when there is corresponding first information. For example, if the first information includes ambient temperature, the first warming-up charging condition includes a condition that the ambient temperature is lower than the ambient threshold temperature. If the first information includes the screen state, the first warming-up charging condition includes a condition that the screen state is an off-screen state, and there is a judgment on the screen state in the first warming-up charging condition in S402. If there is no screen state in the first information, there is no condition for judging the screen state in the first heating and charging condition. If the first information includes the battery temperature and the charging port temperature, the first warm-up charging condition includes that the difference between the battery temperature and the charging port temperature is within a first preset range, and the battery temperature is within a second preset range condition. If the first information includes battery power, the first temperature-raising charging condition includes a condition that the battery power is within a preset power range. If the first information includes battery current, the first temperature-raising charging condition includes a condition that the battery current is greater than a charging threshold current. If the first information includes the charging type, the first heating charging condition includes a condition that the charging type is a preset charging type.

S403: The electronic device sends the first decision information to the battery heating module through the logic control module.

After the logic control module generates the first decision information, the temperature increase decision module may send the first decision information to its first message transceiving module. The first messaging module of the logic control module may send the first decision information to the second messaging module of the battery warming module. Correspondingly, the second message transceiving module of the battery warming module may receive the first decision information from the first message transceiving module of the logic control module.

Wherein, the first decision information includes a temperature raising instruction, and the temperature raising instruction is used to instruct the battery heating module to perform temperature raising processing on the battery.

The second messaging module of the battery warming module receives the first decision information from the first messaging module of the logic control module. Exemplarily, the second message transceiving module may detect whether decision information is received according to the first cycle duration. In case the second messaging module receives the decision information, it may send the decision information to its heating control module. Otherwise, do not send. Wherein, the heating control module may perform heating or stop heating based on relevant instructions of the decision information (for example, a temperature raising instruction or an end temperature raising instruction).

S404: The electronic device sends a first reply message to the logic control module through the battery heating module.

Optionally, after receiving the first decision information from the first message transceiving module of the logic control module through the second message transceiving module, the battery warming module may send the first reply message to the first message transceiving module of the logic control module. Correspondingly, the first message transceiving module of the logic control module may receive the first reply message sent by the second message transceiving module of the battery warming module.

Wherein, the first reply message is a feedback message for the first decision information, and is used to determine that the battery warming module has received the first decision message.

S405: The electronic device obtains the second information through the battery heating module.

After receiving the first decision information, the battery warming module of the electronic device may start to acquire the second information. The second information may include one or more of processor temperature (that is, core temperature), processor heating duration, and the number of times the processor has been heated up so far. Among them, the core temperature can be acquired through the core temperature sensor of the processor module, and the heating time can also be obtained through the processor module. The battery heating module can store the temperature raising times of the processor, and the battery heating module can directly obtain the information of the temperature raising times of the processor. For the acquisition process of the second information, reference may be made to the relevant description in FIG. 3 , and details are not repeated here.

S406: The electronic device controls the processor to run heating through the battery heating module based on the first decision information and the second information.

When the electronic device acquires the first decision information, it can control the operation of the processor based on the second information, so that the heat of the processor heats the battery to increase the temperature of the battery.

In a possible implementation manner, if the cumulative heating times of the processor is less than or equal to the set round, the electronic device controls the processor to run heating periodically within the total heating duration of the current round. That is to say, during the heating process of electronic equipment, the battery heating module can detect the heating time and core temperature when the accumulated heating times are within the set times. During one round of heating, the battery heating module can ensure that the core temperature is within the preset core temperature range, and the control processor operates according to a specific frequency or cycle. When the heating time reaches the total heating time, one round can be ended. heating. In this way, it is possible to ensure that the processor is heated during normal use and at the same time, the limit of the nuclear temperature and the cumulative heating times can be guaranteed, and the life and use of the processor can be ensured.

It should be noted that the execution of S405 and S406 has a small execution cycle, so the order of execution in time may not be limited. For example, while heating according to the second information obtained in the previous cycle, it is also necessary to obtain the next Periodic second information, wherein the number of times and intervals between acquisitions of the second information are not limited.

Before this, the logic control module of the electronic device may determine the charging current based on the battery temperature, wherein the first information acquired by the logic control module includes the battery temperature.

The electronic device may send a first charging instruction to the battery temperature raising module when it is determined by the logic control module that the current battery temperature is within a chargeable temperature range. After the battery warming module receives the first charging instruction, it can charge based on the current charging current.

Specifically, during the heating process, the electronic device can determine the battery temperature through the logic control module, and then determine the charging current corresponding to the current battery temperature based on the mapping relationship between the battery temperature and the charging current range. Table 1 is a mapping relationship between battery temperature and charging current disclosed in an exemplary embodiment of the present application (that is, the first mapping relationship).

Combining the structure of the low-temperature charging system shown in FIG. 3 and FIG. 4A , FIG. 4B provides a schematic flowchart of another low-temperature charging method according to the embodiment of the present application. As shown in FIG. 4B , the electronic device may include a battery heating module, a logic control module, and a battery charging module. For each module, reference may be made to the above-mentioned descriptions in FIG. 2 and FIG. 3 , and details will not be repeated. The low temperature charging method may include but not limited to the following steps:

S421: The electronic device acquires first information through the logic control module.

S422: In the case that heating has not been performed, the electronic device judges whether the first heating charging condition is met through the logic control module based on the first information. If the condition of the first temperature-raising charging is met, execute S403; if the condition of the first temperature-raising charging is not satisfied, do not execute.

When the first temperature-raising charging condition is satisfied, S423 to S428 are executed.

S423: The electronic device sends the first decision information to the battery heating module through the logic control module.

S424: The electronic device sends a first reply message to the logic control module through the battery warming module.

S425: The electronic device obtains the second information through the battery heating module.

S426: The electronic device controls the processor to run heating through the battery heating module based on the first decision information and the second information.

When the electronic device acquires the first decision information, it can control the operation of the processor based on the second information, so that the heat of the processor heats the battery to increase the temperature of the battery.

For the specific operation process of the above S421-S433, reference may be made to the relevant description in FIG. 4A , and details are not repeated here.

Wherein, for the specific steps in FIG. 4B , reference may be made to the relevant description in FIG. 4A , and details are not repeated here.

In the above embodiments, the logic control module of the electronic device may determine whether the first temperature-raising charging condition is met when the first information is acquired. The logic control module does not need to judge whether it is currently in the state of heating or not, but can directly issue charging instructions and decision information for heating if the first heating charging condition is met; Can be used without heating.

In the above implementation manner, the process of judging the electronic device is simplified, and there is no need to judge the heating condition, which can simplify operations, improve processing efficiency, and save resources.

Based on the relevant description of S402 and S407 in FIG. 4A above, FIG. 5 is a schematic flowchart of a method for raising the temperature of a battery disclosed in an embodiment of the present application. As shown in Figure 5, the method for the logic control module to determine the temperature rise decision may include but not limited to the following steps:

S501: Under the condition that the charger is connected, the logic control module starts the charging decision service.

The logic control module can collect the charger status information of the charging port module through the data acquisition module, and then can send the charger status information to the temperature rise decision module through the data acquisition module. For details, reference may be made to related content of acquiring the first information in S401, and details are not repeated.

When the charger state is connected, the temperature rise decision-making module of the logic control module determines the current start-up charging decision-making service.

In the case that the charger state is not connected (unplugged), the temperature rise decision module of the logic control module determines the current end (or stops starting) charging decision service. Specifically, under the condition that the charger changes from the connected state to the non-connected state, the temperature rise decision module determines to end the current charging decision service. Under the condition that the charger remains unconnected, the charging decision service remains disabled.

S502-S504: The logic control module judges whether the first starting condition is met based on the first information. Wherein, the execution order of S502-S504 is not limited. And the first starting condition may include one or more of steps S502-S504. At this time, the first warming-up charging condition in S402 may include a first start-up condition. Wherein, the first starting condition may include one or more of ambient temperature conditions, charging type conditions, and electric quantity conditions. The ambient temperature condition is that the ambient temperature is lower than the ambient threshold temperature, the charging type condition is that the charging type is a preset charging type, and the power condition is that the battery power is within a preset power range. The following is a specific description through S502-S504:

S502: The logic control module judges whether the ambient temperature is lower than the ambient threshold temperature. When the ambient temperature is lower than (or less than or equal to) the ambient threshold temperature, execute S503; when the ambient temperature is not lower than (or greater than) the ambient threshold temperature, execute S505. At this time, the first information includes the ambient temperature.

Wherein, the ambient threshold temperature is a temperature value preset by the logic control module, and the electronic device stores this temperature value.

S503: The logic control module determines whether the charging type is a preset charging type. If the charging type is the preset charging type, execute S504; if the charging type is not the preset charging type, execute S505.

Wherein, the preset charging type may be a fast charging type. The difference between the fast charging type and the non-fast charging type of the charger is the size of the charging power, for example, the fast charging type is the charging type of the charger above 40W; the non-fast charging type is the charging type of the charger below 40W. At this time, the first information includes the charging type. Generally speaking, when the processor is running and heating, the electronic device needs to consume power, and when the charging power of the battery of the electronic device is greater than the power consumption, it can be guaranteed that the battery power is increased. However, in the embodiment of the present application, the preset charging type can ensure heating and charging in a low-temperature environment, and the battery power is increased, thereby ensuring that the battery is generally being charged instead of consuming power.

Optionally, the first information may also include a charging interface type; the logic control module also needs to determine whether the charging interface type is a preset interface type. If the charging interface type is a preset interface type, it may be determined to perform S504; otherwise, perform S505. In fact, the preset interface type may be a Type-C interface.

S504: the logic control module judges whether the battery power is within a preset power range. If the battery power is within the preset power range, execute S507; if the battery power is not within the preset power range, execute S505.

Wherein, the preset power range means that the current power of the charger is the power that needs to be charged, and being outside the preset power range means that the battery does not need to be charged. For example, if the preset power range is less than 99%, charging is required, and S507 is executed; if it is greater than or equal to 99%, charging is not required, S505 is executed. At this time, the first information includes battery power.

S505: the logic control module controls the battery heating module to stop heating.

Specifically, when the logic control module determines that the first start-up condition is not met, the heating charging is not performed (determined not to heat). The logic control module can send the second decision information to the battery warming module. Correspondingly, the battery warming module can receive the second decision information from the logic control module. The second decision information may instruct the battery warming module to stop the current heating process, and the battery warming module may stop heating based on the second decision information (for details, refer to FIG. 6 ).

Optionally, the battery warming module can release the wake lock of charging heating. After the wake-up lock is released, that is, after the electronic device is no longer prevented from entering the sleep state, the logic control module executes the above charging decision service. Before releasing the wake lock, the battery warming module may determine that the electronic device has a wake lock for heating and charging.

It should be noted that after the logic control module determines to stop heating, a second charging instruction may be sent to the battery charging module to stop charging the battery. For details, reference may be made to the descriptions of S413 and S414 above, and details are not repeated here.

S506: The logic control module exits the charging decision service.

After the battery warming module receives the second decision information from the logic control module, it can exit the charging decision service. At this time, the second decision information carries an indication of exiting the charging decision service.

From the process of executing S505 and S506, if the electronic device does not meet the first start-up condition, it will directly exit the current charging decision-making service, that is, the electronic device does not have the basic conditions for low-temperature charging, and there is no need to wait for the charging decision-making service to be started, thereby It can reduce the waste of processing resources and save energy consumption.

S507-S509: The logic control module judges whether the second starting condition is met based on the first information. Wherein, the execution order of S507-S509 is not limited, and the second starting condition may include one or more of steps S507-S509. At this time, the first warming-up charging condition in S402 may include the second start-up condition.

Wherein, the second starting condition may include one or more of current condition, battery temperature, temperature condition of charging port, and screen state condition. The current condition is that the battery current is greater than the charging threshold current; the temperature condition of the battery and charging port is the difference between the battery temperature and the charging port temperature and whether the battery temperature is within the preset temperature range; the screen status condition is that the screen is off. The following is a specific description through S507-S508:

At this time, the first temperature-raising charging condition in S402 may also include a second start-up condition.

S507: The logic control module judges whether the battery current is greater than (or greater than or equal to) the charging threshold current. When the battery current is greater than (or greater than or equal to) the charging threshold current, execute S508; when the battery current is less than or equal to (or less than) the charging threshold current, execute S510.

Wherein, the range of the charging threshold current is preset, specifically obtained through a test in advance. For example, -200mA, which is not limited in this embodiment of the present application. The battery current within the range of the charging threshold current refers to the current in the charging direction of the battery, that is, the current in the battery circuit going in the direction of the battery. At this time, the battery is a consumer of electricity, not a provider.

In the process of processing and heating, it is necessary to consume battery power. In the process of charging electronic equipment, the battery power is increased. In this application, in order to ensure that the battery power is increased, it can be determined by determining the current flowing through the battery When the current is greater than the charging threshold, the charging power is guaranteed to be greater than the discharging power, thereby ensuring heating and charging to ensure an increase in battery power. Wherein, the battery current is the current that the logic control module needs to collect for a period of time to ensure the accuracy of the determined battery current.

S508: the logic control module judges the difference between the battery temperature and the charging port temperature, and whether the battery temperature is within a preset temperature range. When the difference between the battery temperature and the charging port temperature is in the first preset range, and the battery temperature is in the second preset range, execute S509; otherwise, execute S510.

Wherein, the preset temperature range includes a first preset range corresponding to the difference between the battery temperature and the charging port temperature, and a second preset range corresponding to the battery temperature.

Specifically, the logic control module knows the battery temperature T1 and the charging port temperature T2, and when the difference |T1-T2| between the two is in the preset range, it can judge whether |T1-T2| ) a first preset difference (in a first preset range); and determine whether the battery temperature T1 is less than (or less than or equal to) a battery temperature threshold (in a second preset range). If both are satisfied, it is determined to be within the preset range; otherwise, it is not within the preset range. In this way, it can ensure that the temperature of the charging port is normal. When the temperature of the charging port is too high, it means that the port is short-circuited or leaking electricity. In this case, there are problems of use safety and charging safety. This judgment logic can ensure Charging safety.

In addition, it is necessary to increase the battery temperature only when the battery temperature T1 is less than (or less than or equal to) the battery temperature threshold, so as to ensure the condition of the battery.

S509: the logic control module judges whether the screen state is in an off-screen state. In the case of the off-screen state, perform S509; in the case of the on-screen state, perform S510.

Wherein, the logic control module judges whether the screen state is in the off-screen state, and in the case of the off-screen state, it may be determined to execute S509; in the case of the on-screen state, execute S510. In this way, under the condition that the screen state is the bright screen state, it can be determined that the user is using or the electronic device is running the user's related processing operations. In this way, when the user is using the electronic device, it is necessary to ensure that processing resources are provided to the user first, so as to ensure the user's experience and avoid freezing when the user is using the electronic device.

S510: the logic control module controls the battery heating module to suspend heating.

In a possible situation, the logic control module may determine that the second starting condition is not satisfied or the logic control module has completed a round of heating process (S511), and temporarily keep not performing heating (determined not to heat). The logic control module can send the second decision information to the battery warming module. Correspondingly, the battery warming module can receive the second decision information from the logic control module. The heating suspension information may instruct the battery heating module to suspend the current heating treatment (for details, refer to FIG. 6 ). Afterwards, the logic control module may stop the heat treatment, that is, execute S512.

Optionally, the logic control module may be preset with a first sleep duration. After executing S510 or S511, instruct the battery to heat up and stop running the preset program. After the first sleep duration, re-execute S501, that is, start the charging decision service.

It should be noted that, after the logic control module determines to suspend heating, a second charging instruction may be sent to the battery charging module to stop charging the battery. For details, reference may be made to the descriptions of S413 and S414 above, and details are not repeated here.

S511: the logic control module controls the battery heating module to start heating.

Specifically, the logic control module may determine that the second starting condition is met, and start to perform temperature-raising charging (determine heating charging). The logic control module can send the first decision information to the battery warming module. Correspondingly, the battery warming module can receive the first decision information from the logic control module. The heating information may instruct the battery heating module to start the current heating treatment. After performing a round of charging for starting the heating treatment, the logic control module may suspend heating (refer to FIG. 6 for details), that is, execute S510. Wherein, it takes a certain amount of time to perform the step of S511, that is, to perform S510 after the heating process is performed.

Optionally, the electronic device can add a charge heated wake lock. After the wake-up lock is added, the electronic device can be prevented from going to the sleep state, that is, the logic control module can be woken up according to a certain period of time to perform the above-mentioned charging decision-making service. It should be noted that the premise of adding the wake lock above is that there is no added wake lock in the electronic device currently.

It should be noted that after the logic control module determines to start heating, the battery temperature can be collected from time to time, and the first charging instruction can be sent to the battery charging module to charge the battery. For details, reference may be made to the above descriptions of S407 and S408, and details are not repeated here.

In the embodiment of the present application, after the charging decision service is started, the logic control module may determine whether the first starting condition is satisfied, and if the first starting condition is not met, it is determined not to charge and not to raise the temperature. In a case where the first activation condition and the second activation condition are satisfied, warm-up charging may be performed. When the first start-up condition is met but the second start-up condition is not met, charging and heating may be suspended. This can ensure the premise of charging, thereby improving the accuracy and effectiveness of charging decision-making services, ensuring that electronic devices can be heated and charged under the conditions that can be heated and charged, and ensure the safety and reliability of charging and heating .

Referring to FIG. 4A, FIG. 4B and FIG. 5, FIG. 6 is a schematic flowchart of a heat treatment method disclosed in the embodiment of the present application. As shown in Figure 6, for the process of the above-mentioned battery heating module based on the decision-making information and the processor heating information to control the processor to run and heat, the specific description is as follows:

It should be noted that in FIG. 4A , the specific process of S406 and S410 may be the operation process in FIG. 6 .

S601: The battery heating module starts the heating service.

After the battery heating module starts the heating service, S602 and subsequent steps may be executed.

S602: The battery warming module acquires decision information according to the length of the first cycle.

After the battery warming module starts the heating service, the decision information may be periodically monitored by the second messaging module. That is, it is detected whether decision information is received according to the length of the second cycle. In case the decision information is received, the second messaging module may send the decision information to the heating control module. The battery heating module can start the heating process or end the heating process based on the decision information through the heating control module.

Wherein, the decision information may be first decision information or second decision information. When the first decision information is received, it may be determined to perform heating, and after the second decision information is received, it may be determined to stop the current heating process.

S603: The battery heating module judges whether to perform heating based on the decision information when the battery heating module obtains the decision information. If it is determined that heating is to be performed, S605 is performed; when heating is not performed, S604 is performed.

The battery warming module can judge whether to perform heating based on the decision information through the heating and warming module. When the heating and temperature raising module receives the first decision information, the first decision information includes a temperature raising instruction, and the heating and temperature raising module may determine to perform heating based on the temperature raising instruction, that is, execute S605. In the case that the heating and warming module receives the second decision information, the second decision information includes an instruction to end the temperature raising, and the heating and warming module may determine to stop heating based on the instruction to end the temperature raising, that is, execute S604.

S604: The battery heating module exits the heating service.

The battery heating module determines to stop heating through the heating module, and then exits the heating service, that is, ends the execution of the current heating software program. If it is currently in a heating process, the heating and warming module can directly stop the heating process and exit the heating service. Specifically, it can be regarded as the process of executing S412.

S605-S611 are the specific process of one round of heating by the battery heating module, which may be the specific process of the above-mentioned S406.

S605: The battery heating module starts a round of heating process.

The battery heating module can start a round of heating process by heating the heating module.

Wherein, the execution mode of a specific round of heating process is different, and needs to be predefined specifically. For example, each round of heating is K times, the duration of each continuous heating is M, and the interval between two adjacent heating start times is N, where N>M. Specifically, the steps of S606 to S611 are described in detail.

S606: The battery heating module determines the processor core running heating.

The number of cores of the processor of the electronic device may be different, for example, a processor with 4 cores or 8 cores. Among them, one core needs to execute the charging decision service of the logic control module and the heating service of the battery heating module, and the remaining one-core or multi-core processors can execute preset programs for heating. Wherein, the preset program may be a program for reading the memory of the electronic device, and the specific function is not limited.

Optionally, the electronic device may determine the number of processor cores to be heated based on the core temperature. In a possible situation, when the core temperature is greater than the first temperature threshold, heating is performed according to the number of cores of the processor according to the first ratio (the number of processor cores running and heated is the product of the total number of processor cores and the first ratio ). When the core temperature is less than or equal to the first temperature threshold and greater than the second temperature threshold, heating is performed according to the number of cores of the processor in a second proportion. In the case that the core temperature is less than or equal to the second temperature threshold, heating is performed according to a third ratio of the number of cores of the processor. Wherein, the first temperature threshold is greater than the second temperature threshold, and the second temperature threshold is greater than the third temperature threshold. The first ratio is smaller than the second ratio, and the second ratio is smaller than the third ratio. That is, the higher the core temperature, the fewer the number of processor cores.

Exemplarily, the number of current processor cores is 8, the first temperature threshold is 5 degrees Celsius, the second temperature threshold is -5 degrees Celsius, and the third temperature threshold is -15 degrees Celsius. The first ratio is 3/8, the second ratio is 3/4, and the third ratio is 7/8. If the number of processor cores available for heating is 7. If the current core temperature is 6 degrees Celsius, 8*3/8 means the number of processor cores is 3; if the current core temperature is -6 degrees Celsius, 8*5/8 means the number of processor cores is 5; if the current core temperature is -16 degrees Celsius, 8*7/8, that is, the number of processor cores is 7. In this way, the lower the core temperature, the more the number of processor cores, which can ensure that the processor module heats up faster, and at the same time call the resources of the processor core as little as possible, reduce the loss of the processor, prolong the service life of electronic equipment, and slow down Stuck and stopped.

Optionally, when the number of cores running heating and the number of cores executing the heating strategy remain unchanged in each round, the electronic device allocates the cores running heating in the current heating round in turn based on the historical core allocation results of the processor. Kernel and the kernel that implements the heating strategy. That is, the battery heating module of the electronic device agrees on a preset number of processor cores to perform heating, and performs heating in turn according to the heating and heating rounds, or the cores of the processor cores that perform charging decision service and heating service execute in turn. At least one processor core is required to execute the heating strategy; at least one processor core is required to execute the running heating process of the processor.

Exemplarily, the number of processor cores of the electronic device is 8, and the preset number is 7. Assume that the processor cores are n1, n2, n3, n4, n5, n6, n7, and n8, respectively. In the first round, n1 executes the logic control module and battery heating module, and n2~n8 executes the preset program; in the second round, n2 executes the logic control module and battery heating module, and n1, n3~n8 execute the preset program; in the third round, n3 executes the logic control module and the battery heating module, n1, n2, n4~n8 execute the preset program... In this way, it can ensure that the core consumption of each processor is similar as much as possible, so as to prolong the service life of electronic equipment. Delay lag.

S607: The battery heating module judges whether the accumulated heating times are within the set times. If it is within the set times, execute S608; otherwise, execute S604.

The battery heating module can store the accumulated heating times through the heating control module. In the case that the current accumulated heating times are less than (less than or equal to) the set times, it is determined that the accumulated heating times are within the set times, and the times of the temperature-raising operation can be determined. It is judging whether the cumulative heating times are within the set times. Wherein, the accumulative heating times are the total number of heating rounds activated by the battery heating module, and the accumulated times from the time the electronic equipment leaves the factory to the current heating rounds. In this way, the processor can stop the heating service within the set number of times, that is, no heating; if the set number of times has exceeded, it can be heated. It can effectively control the number of times the processor runs at full load, the number of times the controller runs, and the aging degree, thereby delaying the occurrence of freezes and improving user experience.

Wherein, the execution sequence of S607 may be before S608, and is not specifically limited.

S608: the battery heating module controls the processor core to run and heat at full load.

The battery heating module can control the processor core to run at full load through the temperature raising decision-making module. The processor will generate heat during operation, and the heat will be transferred to the battery module through the cooling plate, which will increase the temperature of the battery. In this way, without a specific heating hardware module, the processor can be used to heat the battery to ensure that the temperature of the battery reaches a temperature that can be charged.

Specifically, the battery warming module of the electronic device can control the processor core in one round of heating through the temperature raising decision-making module. Second-rate. The duration of each continuous operation is M, the waiting time is H, and the interval between two adjacent heating start times is N (heating cycle duration N=M+H), X=N*K. It can be seen that a heating cycle of the processor is composed of running time and waiting time. The running time is the heating time of the processor in one cycle, and the waiting time is the non-heating time of the processor in one cycle.

Exemplarily, the total heating time X is 150 min, the cumulative heating times K is 50, the running time is 2 min (M), the waiting time (H) is 1 min, and the interval N between two adjacent heating start times is 3 min.

Optionally, in the above-mentioned round of heating process, the heating is periodic heating, such as the above-mentioned heating for 2 minutes (M), waiting for 1 minute; reheating for 2 minutes... Repeat the operation in this way, such a heating process is to ensure that the nuclear temperature is Within the preset core temperature range, the safety of electronic equipment can be guaranteed. For a low-temperature charging environment, when the electronic device is heated, it will maintain a higher temperature, or the core temperature will rise; when the heating is stopped, the lower the ambient temperature, the faster the core temperature and battery temperature will cool down. The battery warming module of the electronic device can determine the heating frequency or the ratio of the running time to the waiting time based on the ambient temperature (or the core temperature when not heated) (the cycle time is constant). The lower the ambient temperature (or the core temperature when not heated), the higher the corresponding heating frequency or the ratio of the running time to the waiting time.

Exemplarily, the battery warming module of the electronic device may store a mapping relationship between the ambient temperature and the ratio of the heating duration to the waiting duration. After the electronic device obtains the ambient temperature before heating, the ratio of the heating time to the waiting time can be determined based on the above mapping relationship, so that the ratio of the heating time to the waiting time can be determined. For example, when the ambient temperature is -5 degrees, heat for 2 minutes and wait for 1 minute; when the ambient temperature is -15 degrees, wait for 3 minutes with an interval of 1 minute. In this way, it can be ensured that in different ambient temperatures, the electronic device can adaptively determine the heating time, ensure that the temperature is within a specific temperature range as much as possible, ensure that the charging time is as long as possible, and ensure the effectiveness of charging.

S609: The battery heating module judges whether the heating time reaches the total heating time. If the preset heating duration is reached, S610 may be executed; if the preset heating duration is not reached, S611 may be executed.

When the battery heating module controls the processor core to heat, it starts timing. When the heating time reaches the total heating time, it ends the current round of heating and executes S610; when the heating time does not reach the total heating time, it continues heating and executes S611.

Optionally, the total heating time required by different batteries is different. The lower the battery power is, the longer the charging time needs to be, and the longer the heating time should be; the higher the battery power, the shorter the charging time should be. Therefore, based on the electronic device, the mapping relationship between the battery power and the heating duration (or the functional relationship between the battery power and the heating duration) can be determined in advance. After determining the current core temperature, the battery power can be used to determine the required heating for one round. The length of time (total heating time). Afterwards, the battery warming module may perform heating based on the determined first total heating duration (X). The lower the battery power, the longer the total duration of the first heating. In this way, it can be ensured that one round of heating can make the power of the electronic device fully or nearly fully charged, thereby avoiding the situation that one round of heating is not fully charged and then reheated, or overheated, thereby saving the processing resources consumed by heating and ensuring the long charging time. accuracy.

For example, assume that the battery warming module of the electronic device stores the mapping relationship between the battery power and the heating duration. The mapping relationship is, when the battery power is 0-5%, the total heating time is 150 minutes; when the battery power is 5-20 %, the total heating time is 120min; when the battery power is 20-50%, the total heating time is 100min; when the battery power is 50-70%, the total heating time is 60min; when the battery power is 70-85%, the total heating time 30 minutes; when the battery power is 85-99%, the total heating time is 15 minutes. Based on the above mapping relationship, if the current power is 30%, the electronic device can determine that the total duration of the first heating is 100 minutes, that is, the total duration of one round of heating will be heated according to the above duration, and once 100 minutes arrives, this round of heating will end.

S610: The battery warming module acquires the core temperature, and sleeps for the first sleep duration when the core temperature exceeds the first core temperature value; continues heating when the core temperature is lower than the second core temperature value.

The battery temperature raising module can preset the core temperature range through the temperature raising decision module. The core temperature range includes a first core temperature value and a second core temperature value. When the core temperature exceeds the first core temperature value, the electronic device can sleep for the first sleep period, that is, suspend the first sleep period during the current round of heating; when it is lower than the second core temperature value, keep heating, That is, continue to execute S608. Wherein, the first sleep duration is less than the total preset heating duration. The first core temperature value is greater than or equal to the second core temperature value. In this way, it can ensure that the core temperature is heated within a certain temperature range, which can not only ensure that the battery is heated, but also prevent the temperature of the processor from being too high, which will damage the processor and ensure the safety of the heating process. and processor security.

Exemplarily, the first core temperature value is 50 degrees Celsius, and the second core temperature value is 10 degrees Celsius. When the current core temperature is greater than 50 degrees Celsius, pause for 20 minutes (the first sleep duration); when the current core temperature is lower than 10 degrees Celsius, continue to start heating.

Exemplarily, both the first core temperature value and the second core temperature value are 30 degrees Celsius. When the current core temperature is greater than 30 degrees Celsius, pause for 20 minutes (the first sleep duration); when the current core temperature is lower than 30 degrees Celsius, continue to start heating.
