First of all, to solve the problem of battery consistency, it is necessary to balance each battery cell through a balanced method. Among them, during the operation of the drone, the intermittent time of the charge and discharge cycle is short, and the battery has almost no resting time. In order to achieve a better balance effect, the balance processing of the battery needs to stand for a period of time before the balance can begin. Therefore, in this scenario , The battery is more difficult to enter equilibrium. However, this application does not consider the use of active equalization, because active equalization will increase the cost of wires, connectors, etc., and will lengthen the charging time. In this way, more batteries are required to complete the cycle, which further increases the cost. Therefore, this application proposes a battery equalization method, which can make the battery do not need to be left for a long time, as long as the charging and discharging is stopped, the equalization process can be started, so that the battery maintains a higher consistency, and when there is a chance to stand for a long time Enter the equalization process to optimize the equalization effect of the battery, where the above two equalization processes are not the same. Several embodiments are used below to describe the solution of the present application in detail.

FIG. 2 is a flowchart of a battery balancing method provided by an embodiment of this application. As shown in FIG. 2, the method of this embodiment may include:

S201: After it is determined that the charging and discharging of the battery are stopped, perform an equalization process on the battery according to the first equalization strategy.

In this embodiment, after it is determined that the charging of the battery is stopped and the discharging is also stopped, the battery is equalized according to the first equalization strategy. For example, when it is determined that the charging and discharging of the battery stop for a certain period of time, the equalization processing of the battery is started according to the first equalization strategy, and the certain period of time may be a very short period of time. For another example, when it is determined that the charging and discharging of the battery is stopped, the equalization processing of the battery is started according to the first equalization strategy. The certain period of time may be a short period of time, or when the charging and discharging of the battery is stopped, the equalization process is started according to the The strategy performs equalization processing on the battery.

Wherein, the battery may include an equalization circuit, and performing equalization processing on the battery may be, for example, controlling the equalization circuit to perform equalization processing on the battery. The equalization circuit may be, for example, a resistor, and the battery is discharged through the resistor to realize the equalization processing of the battery. Optionally, the equalization circuit is installed within a preset range of the part to be heated. Since the equalization circuit generates heat during the equalization process of the battery, in order to make full use of the heat, the equalization circuit can be installed close to the part to be heated. So that the heat generated above can be used to heat the part to be heated, which also improves the heat dissipation efficiency of the battery and avoids the temperature of the battery from being too high.

S202: When or after performing equalization processing on the battery according to the first equalization strategy, obtain a first duration of a time period between the current time and the battery charging and discharging stop time.

In this embodiment, when the battery is equalized according to the first equalization strategy, the time period between the current time and the battery charging and discharging stop time starts to be obtained, and then the current time and the time period can be updated in real time. The duration of the time period between the battery charging and discharging stop time. Alternatively, after performing the equalization processing on the battery according to the first equalization strategy, start to obtain the duration of the time period between the current time and the battery charging and discharging stop time, and then the current time and the battery charging and discharging can be updated in real time. The duration of the time period between stop times. After performing the equalization processing on the battery according to the first equalization strategy, for example, it may be when the equalization processing on the battery according to the first equalization strategy ends.

Wherein, the duration of the time period between the acquired current time and the battery charging and discharging stop time is referred to as the first duration.

S203: If it is determined according to the first duration that the first preset trigger condition is satisfied, perform equalization processing on the battery according to a second equalization strategy.

In this embodiment, after acquiring the first duration of the time period between the current time and the battery charging and discharging stop time, it is determined whether the first preset trigger condition is satisfied according to the first duration. If it is determined that the first preset trigger condition is satisfied according to the first duration, the battery is equalized according to the second equalization strategy. If it is determined according to the first duration that the first preset trigger condition is not satisfied, the battery is not equalized according to the second equalization strategy. Among them, the second equilibrium strategy is an equilibrium strategy different from the first equilibrium strategy.

Optionally, if the first duration is greater than or equal to a first preset duration, it is determined that the first preset trigger condition is satisfied. In this embodiment, after acquiring the first duration of the time period between the current time and the battery charging and discharging stop time, it is determined whether the first duration is less than the first preset duration, and if the first duration is greater than or equal to the first preset duration , The battery is equalized according to the second equalization strategy, that is, the battery is equalized according to the second equalization strategy at the current time. If the first time period is less than the first preset time period, the battery is not equalized according to the second equalization strategy. This means that the battery has been standing still for a sufficient period of time for the equalization process.

It should be noted that the first preset duration is greater than the certain duration mentioned in S201.

In the battery balancing method of this embodiment, under different conditions, the battery is balanced according to two different balancing strategies. After the battery charging and discharging stop, the battery is equalized according to the first equalization strategy to determine that the battery has a certain consistency, and then when or after the equalization process is performed on the battery according to the first equalization strategy, If it is determined that the first preset trigger condition is satisfied according to the first duration of the time period between the current time and the battery charging and discharging stop time, the battery is equalized according to the second equalization strategy, and it is determined that the battery is left alone enough Time length to perform equalization processing to further optimize the consistency of the battery. The defect in the prior art that the battery does not have enough time to enter the battery balance is avoided, the consistency of the battery is improved, and the accuracy of the battery power is also ensured.

In some embodiments, the first equalization strategy in S201 above includes: when it is determined that the first preset stop condition is satisfied according to the electrical parameters of the battery, stopping the equalization processing on the battery. Correspondingly, a possible implementation of S201 is to obtain the electrical parameters of the battery, and determine whether the first preset stop condition is satisfied according to the electrical parameters of the battery, and if it is determined that the first preset stop condition is satisfied according to the electrical parameters of the battery, When the condition is met, the equalization processing of the battery is stopped. Wherein, obtaining the electrical parameters of the battery may be obtained in real time or according to a preset period. If it is determined according to the electrical parameters of the battery that the first preset stop condition is not satisfied, the battery is continuously balanced.

Optionally, the electrical parameter of the battery includes the electrical parameter difference between the maximum electrical parameter of the battery cell and the minimum electrical parameter of the battery cell in the battery. The battery includes a plurality of cells. The above-mentioned obtaining of the electrical parameters of the battery may be to obtain the electrical parameters of the cells in the battery, and determine the electrical parameters of the cell with the largest value (that is, the largest electrical parameter) and the cell with the smallest value. The electrical parameter (that is, the minimum electrical parameter), and then obtain the electrical parameter difference between the maximum electrical parameter and the minimum electrical parameter. In this embodiment, the electrical parameter value is used as the electrical parameter of the battery. The electrical parameters may include voltage or capacitance, for example.

Optionally, a possible implementation for determining that the first preset stop condition is satisfied according to the electrical parameters of the battery is: if the electrical parameter difference is less than or equal to the first preset difference, determining that the first preset is satisfied Set the stop condition. In this embodiment, after the electrical parameter difference is obtained, for example, as shown in FIG. 3, it is determined whether the electrical parameter difference is greater than the first preset difference, and if the electrical parameter difference is less than or equal to the first preset difference , Then stop balancing the battery. If the electrical parameter difference is greater than the first preset difference, the battery will continue to be balanced.

In some embodiments, the second equalization strategy in S203 above includes: when it is determined that the second preset stop condition is satisfied according to the electrical parameters of the battery, stopping the equalization processing on the battery. Correspondingly, one possible implementation of S203 is to obtain the electrical parameters of the battery, and determine whether the second preset stop condition is satisfied according to the electrical parameters of the battery, and if it is determined that the second preset stop condition is satisfied according to the electrical parameters of the battery, When the condition is met, the equalization processing of the battery is stopped. Wherein, obtaining the electrical parameters of the battery may be obtained in real time or according to a preset period. If it is determined according to the electrical parameters of the battery that the second preset stop condition is not met, the battery is continuously balanced.

Optionally, the electrical parameter of the battery includes the electrical parameter difference between the maximum electrical parameter of the battery cell and the minimum electrical parameter of the battery cell in the battery.

Optionally, a possible implementation for determining that the second preset stop condition is satisfied according to the electrical parameters of the battery is: if the electrical parameter difference is less than or equal to the second preset difference, determining that the second preset is satisfied Set the stop condition. In this embodiment, after the electrical parameter difference is obtained, for example, as shown in FIG. 3, it is determined whether the electrical parameter difference is greater than the second preset difference, and if the electrical parameter difference is less than or equal to the second preset difference , Then stop balancing the battery. If the electrical parameter difference is greater than the second preset difference, the battery will continue to be balanced.

Wherein, the second preset difference is smaller than the first preset difference. If the electrical parameter difference is a voltage difference, the first preset difference is, for example, 30 mV, and the second preset difference is, for example, 10 mV. If the electrical parameter difference is the electrical capacity difference, the first preset difference is, for example, 3% of the battery design capacity, and the second preset difference is, for example, 1% of the battery design capacity. Among them, the battery design capacity is the nominal capacity of the battery. Since the electrical parameter difference after the battery is equalized according to the second equalization strategy is smaller than the electrical parameter difference after the battery is equalized according to the first equalization strategy, after the battery is equalized according to the first equalization strategy, It can ensure that the battery has a certain consistency, and then after the battery is balanced according to the second balancing strategy, the consistency of the battery is optimized. The foregoing balancing processing of the battery according to the first balancing strategy may be referred to as coarse balancing, and the foregoing balancing processing of the battery according to the second balancing strategy may be referred to as fine balancing.

In some embodiments, a possible implementation manner of performing equalization processing on the battery according to the second equalization strategy in S203 is: if it is determined that the second preset trigger condition is satisfied according to the electrical parameters of the battery, then The second equalization strategy performs equalization processing on the battery. In this embodiment, the electrical parameters of the battery are acquired, and the second preset trigger condition is determined according to the electrical parameters of the battery. If it is determined according to the electrical parameters of the battery that the second preset trigger condition is met and the first duration is determined When the first preset trigger condition is satisfied, the battery is equalized according to the second equalization strategy. Wherein, obtaining the electrical parameters of the battery may be obtained in real time or according to a preset period. If it is determined according to the electrical parameters of the battery that the second preset trigger condition is not met or the first duration is less than or equal to the first preset duration, the battery is not balanced according to the second balance strategy, and the electrical parameters of the battery can be continuously acquired.

Optionally, a possible implementation manner for determining that the second preset trigger condition is satisfied according to the electrical parameters of the battery is: if the electrical parameter difference is greater than the third preset difference, it is determined that the second preset is satisfied Triggering conditions. In this embodiment, after the electrical parameter difference is obtained, for example, as shown in FIG. 3, it is determined whether the electrical parameter difference is greater than the third preset difference, and if the electrical parameter difference is greater than the third preset difference and If the first time period is greater than the first preset time period, the battery is equalized according to the second equalization strategy. If the electrical parameter difference is less than or equal to the third preset difference or the first duration is less than or equal to the first preset duration, the battery is not balanced according to the second balance strategy.

In some embodiments, a possible implementation manner of performing equalization processing on the battery according to the first equalization strategy in S201 is: if it is determined that the third preset trigger condition is satisfied according to the electrical parameters of the battery, then according to The first equalization strategy performs equalization processing on the battery. In this embodiment, after the charge and discharge are completed, the electrical parameters of the battery are acquired, and the third preset trigger condition is determined according to the electrical parameters of the battery. If the third preset trigger condition is determined to be met according to the electrical parameters of the battery, then The battery is equalized according to the first equalization strategy. Wherein, obtaining the electrical parameters of the battery may be obtained in real time or according to a preset period. If it is determined according to the electrical parameters of the battery that the third preset trigger condition is not satisfied, the battery is not equalized according to the first equalization strategy, and the electrical parameters of the battery can be continuously acquired.

Optionally, a possible implementation for determining that the third preset trigger condition is satisfied according to the electrical parameters of the battery is: if the electrical parameter difference is greater than the fourth preset difference, it is determined that the third preset is satisfied Triggering conditions. In this embodiment, after the charge and discharge are completed, after the electrical parameter difference is obtained, for example, as shown in FIG. 3, it is determined whether the electrical parameter difference is greater than the fourth preset difference, and if the electrical parameter difference is greater than the first Four preset differences, the battery is equalized according to the first equalization strategy. If the electrical parameter difference is less than or equal to the fourth preset difference, the battery is not equalized according to the first equalization strategy.

Optionally, the fourth preset difference value may be greater than the third preset difference value. If the electrical parameter difference is a voltage difference, the fourth preset difference is, for example, 50 mV, and the third preset difference is, for example, 20 mV. If the electrical parameter difference is the electrical capacity difference, the fourth preset difference is, for example, 5% of the battery design capacity, and the third preset difference is, for example, 2% of the battery design capacity. Among them, the battery design capacity is the nominal capacity of the battery.

Optionally, the fourth preset difference is greater than or equal to the second preset difference. Optionally, the third preset difference is greater than or equal to the first preset difference.

In some embodiments, a possible implementation manner of performing equalization processing on the battery according to the first equalization strategy in S201 is: acquiring the second time period between the current time and the battery charging and discharging stop time. Duration; if the second duration is less than a second preset duration, the battery is balanced according to a first balance strategy; wherein, the second preset duration is less than or equal to the first preset duration.

In this embodiment, after the battery charging and discharging stops, the duration of the time period between the current time and the battery charging and discharging stop time is acquired, and this duration is referred to as the second duration. For example, as shown in Figure 3, it is then determined whether the second duration is less than the second preset duration. If the second duration is less than the second preset duration, it means that the battery has not been standing for a long time, and it has not yet reached the second balance strategy. If the battery is equalized, the battery is equalized according to a first equalization strategy that is different from the second equalization strategy. If the second duration is greater than or equal to the second duration, the battery is not balanced according to the first balance strategy. Instead, it continues to determine whether the second duration is greater than the second preset duration, and if the second duration is greater than the second preset duration, the battery is equalized according to the second equalization strategy.

It should be noted that, with regard to the manner of performing balancing processing on the battery according to the first balancing strategy, if there is no contradiction between the foregoing implementation manners, they can be combined with each other arbitrarily. Regarding the method of performing equalization processing on the battery according to the second equalization strategy, if there is no contradiction between the foregoing implementation methods, they can be combined with each other arbitrarily. Regarding the method of performing equalization processing on the battery according to the second equalization strategy and the method of performing equalization processing on the battery according to the first equalization strategy, if there is no contradiction between the foregoing implementation methods, they can be combined arbitrarily.

In addition to the foregoing determination of satisfying the first preset stop condition according to the electrical parameters of the battery, the following is a solution for how to stop the equalization processing of the battery during the equalization processing of the battery according to the first equalization strategy in S201 Describe.

In some embodiments, in the process of performing equalization processing on the battery according to the first equalization strategy in S201, the third time period for equalizing the battery according to the first equalization strategy is also acquired, if the If the third time period is greater than or equal to the third preset time period, the equalization processing of the battery is stopped.

In this embodiment, when starting to perform equalization processing on the battery according to the first equalization strategy, start timing, and the timed duration is the third duration. During the equalization processing of the battery according to the first equalization strategy, Acquire the third duration in real time or acquire the third duration according to a certain period. Then determine whether the third duration is less than the third preset duration, if the third duration is greater than or equal to the third preset duration, if the equalization processing of the battery is not stopped at this time, it indicates that the battery is equalized according to the first equalization strategy When the processing times out, the balancing processing of the battery is stopped. If the third time period is less than or equal to the third preset time period, it indicates that the equalization processing of the battery according to the first equalization strategy has timed out. If the equalization processing of the battery is not stopped at this time, the equalization processing of the battery is continued.

In some embodiments, in the process of performing equalization processing on the battery according to the first equalization strategy in S201, if it is detected that the charger is connected to the battery, the equalization processing on the battery is stopped. When it is detected that the charger is connected to the battery, it indicates that the user wants to charge the battery. At this time, it is necessary to stop the equalization process of the battery to facilitate the battery charging process.
