Please refer to Fig. 3, it illustrates the method flow diagram of the predetermined battery recognition methods that another embodiment of the disclosure provides.The present embodiment illustrates for the total volume calculating battery in the process of battery discharge, and this predetermined battery recognition methods, can comprise the steps:

In step 301, in discharge process, the first open-circuit voltage of sampling battery, and in preset relation, inquire about the first dump energy corresponding to the first open-circuit voltage;

Electronic equipment in discharge process, the first open-circuit voltage of sampling battery, and inquire about the first dump energy corresponding to the first open-circuit voltage in preset relation.Wherein, open-circuit voltage be battery when without any load with without any electric current, the voltage at battery two ends.Preset relation is the chemical characteristic according to battery, the corresponding relation between the different open-circuit voltage of predetermined battery and different dump energies.Also be the charging management chip in electronic equipment, the first open-circuit voltage of sampling battery in discharge process, and this first open-circuit voltage is sent to processor, by processor according to the first dump energy inquired about in the preset relation stored in memory corresponding to the first open-circuit voltage.

Such as, obtain the electric current in battery discharge procedure, carry out time integral obtain discharge electricity amount to this electric current, this time is the time between the sampling instant of the first open-circuit voltage and the sampling instant of the second open-circuit voltage.

In step 304, according to the total volume of following formulae discovery battery:

Charge capacity/(the second dump energy-the first dump energy).

Such as, if discharge electricity amount is Y, the first dump energy I, the second dump energy is L, then pass through Y/(I-L) calculate the total volume of battery.

In step 305, whether the total volume that detection computations obtains mates with the total volume of predetermined battery;

Whether the total volume that detection computations obtains mates with the total volume of predetermined battery, can be whether the total volume that detection computations arrives is the same with the total volume size of predetermined battery, can also be to detect difference between the two whether within a predetermined threshold.

Also the total volume that even detection computations obtains is mated with the total volume of predetermined battery, then illustrating that battery total capacity is the same with predetermined battery, then can be predetermined battery by battery identification.

In actual applications, different batteries has different charging voltages, if use not corresponding with it charging voltage to charge to it to battery, if charging voltage is higher than charging voltage corresponding to battery, then can damage battery; If battery lower than charging voltage corresponding to battery, then can not be full of electricity by charging voltage.

Along with more and more higher to the requirement of battery energy density, adopt the battery that charging voltage is higher, not only can improve the total volume of battery, can also the duration of charging be shortened.Such as, originally had standard charge voltage to only have 4.2V, the charging voltage that some battery uses now reaches 4.35V.

As shown in Figure 4 A, the charging process of battery is divided into three parts, Part I: when the voltage of cell voltage lower than an A place, first battery is had to the process of individual precharge, and also namely moment 0 to moment T1 is pre-charge process during this period of time; Part II: in the process of charging, during voltage higher than an A place of the voltage of battery, enter constant-current charge process, until the some B place that moment T2 is corresponding, now the voltage of battery is close to a fixed value, namely also the voltage of battery reaches capacity state, and also namely moment T1 enters constant-current charge process during this period of time to moment T2; Part III: after the voltage of battery reaches capacity state, enter constant-voltage charge process, in constant-voltage charge process, selects a fixing voltage to charge to battery, the time period that namely moment T2 is later, specifically will select according to the actual conditions of battery.Such as, the voltage of common batteries 4.2V carries out constant-voltage charge, and some battery adopts the voltage of 4.35V to carry out constant-voltage charge.

Please refer to Fig. 4 B, it illustrates the method flow diagram of the predetermined battery recognition methods that disclosure embodiment provides.In the present embodiment, suppose that the predetermined charge voltages of predetermined battery is 4.35V, in constant-current charging of battery process, calculate the total volume of battery, and whether identify battery be predetermined battery; When the voltage of battery reaches capacity state, the result according to identifying selects voltage battery being carried out to constant-voltage charge to illustrate.This predetermined battery recognition methods, can comprise the steps:

In step 401, judge that whether the open-circuit voltage of battery is higher than standard charge voltage before charging;

Electronic equipment judges that whether the open-circuit voltage of battery is higher than standard charge voltage before charging.Wherein, open-circuit voltage be battery when without any load with without any electric current, the voltage at battery two ends.Standard charge voltage shows the voltage that common batteries carries out in constant-voltage charge process, less than the predetermined charge voltages of predetermined battery in the present embodiment.

When the predetermined charge voltages corresponding to predetermined battery is higher than standard charge voltage, need to judge that whether the open-circuit voltage of battery is higher than standard charge voltage before charging, predetermined charge voltages is the voltage carried out predetermined battery in constant-voltage charge process, the open-circuit voltage of battery can be that electronic equipment put into by battery, the voltage detected when just having opened electronic equipment.

In step 402, if judged result is higher than standard charge voltage, then direct is predetermined battery by battery identification;

If judged result is higher than standard charge voltage, then battery identification is directly predetermined battery by electronic equipment.If the open-circuit voltage of battery is higher than standard charge voltage, so just illustrate that the voltage that can charge to this battery is higher than standard charge voltage, so can be directly predetermined battery by battery identification, be predetermined battery by this battery identification, can turn to and perform step 409.

In step 403, if judged result is not higher than standard charge voltage, then whether the difference continued between criterion charging voltage and the open-circuit voltage of battery exceedes predetermined threshold;

If judged result is not higher than standard charge voltage, then whether the difference that electronic equipment continues between criterion charging voltage and the open-circuit voltage of battery exceedes predetermined threshold.If the open-circuit voltage of battery is not higher than standard charge voltage, so directly cannot judge that the voltage that can charge to this battery is higher than standard charge voltage, or normal voltage, so need to do further judgement to this battery, need the difference continued between criterion charging voltage and the open-circuit voltage of battery whether to exceed predetermined threshold, also, the open-circuit voltage of standard charge voltage and battery is done difference operation, draw difference therebetween, this difference and predetermined threshold are compared.

In step 404, if judged result is for exceeding predetermined threshold, then perform the step calculating the total volume of battery according to the open-circuit voltage in the charging process of battery and preset relation;

If judged result is for exceeding predetermined threshold, then electronic equipment performs the step calculating the total volume of battery according to the open-circuit voltage in the charging process of battery and preset relation.Also the difference even between standard charge voltage and the open-circuit voltage of battery exceedes predetermined threshold, also needs to continue the step performed below and judges whether this battery is predetermined battery further, namely perform step 406.

Such as, if standard charge voltage is 4.2V, the open-circuit voltage of battery is 3.9V, and predetermined threshold is 0.1V, the difference obtained between standard charge voltage and the open-circuit voltage of battery is that 0.3V is greater than 0.1V, then need to continue the step performed below and judge whether this battery is predetermined battery further.

In step 405, if judged result is for being no more than predetermined threshold, then battery is discharged;

If judged result is for being no more than predetermined threshold, then electronic equipment discharges to battery.

If the difference between standard charge voltage and the open-circuit voltage of battery does not exceed predetermined threshold, directly cannot judge whether this battery is predetermined battery, namely constant-voltage charge can not be carried out by predetermined charge voltages to this battery, so for security consideration, need to discharge to this battery, can discharging by using electronic equipment, also can discharge by arranging a discharge circuit in charging management chip in the electronic device.After this battery carries out electric discharge a period of time, perform step 406, judge whether this battery is predetermined battery further.

In a step 406, according at least twice open-circuit voltage of battery and the total volume of preset relation calculating battery;

Electronic equipment calculates the total volume of battery according at least twice open-circuit voltage of battery and preset relation.Preset relation is the corresponding relation between the different open-circuit voltage of predetermined battery and different dump energies.

Electronic equipment calculates the total volume of battery according at least twice open-circuit voltage of battery and preset relation, and this step comprises following sub-step:

1, electronic equipment is in charging process, the first open-circuit voltage of sampling battery, and in preset relation, inquire about the first dump energy corresponding to the first open-circuit voltage;

In preset relation, inquire about the first dump energy corresponding to the first open-circuit voltage, following sub-step can be comprised:

Such as, first open-circuit voltage is 3.642V, electronic equipment detects that 3.642V does not exist in predetermined relationship, then inquiry is adjacent with the first open-circuit voltage 3.642V and be less than the reference open-circuit voltage 3.639V of the first open-circuit voltage, adjacent with the first open-circuit voltage and be greater than the reference open-circuit voltage 3.665V of the first open-circuit voltage, and the dump energy inquired with reference to open-circuit voltage 3.639V is corresponding is 6, reference open-circuit voltage 3.665V is 7, pass through formula: dump energy a+(dump energy b-dump energy is * (the first open-circuit voltage-reference open-circuit voltage A) a)/(with reference to open-circuit voltage B-with reference to open-circuit voltage A), also be (7-6)/(3.665-3.639) * (3.642-3.639)=6.1154, the first dump energy calculated corresponding to the first open-circuit voltage is 6.1154.

2, the second open-circuit voltage of electronic equipment sampling battery, and in preset relation, inquire about the second dump energy corresponding to the second open-circuit voltage;

3, electronic equipment carries out integration to the charging current between the sampling instant of the first open-circuit voltage and the sampling instant of the second open-circuit voltage and obtains charge capacity;

4, electronic equipment is according to the total volume of following formulae discovery battery:

Charge capacity/(the second dump energy-the first dump energy).

In step 407, whether the total volume that detection computations obtains mates with the total volume of predetermined battery;

Whether the total volume that electronic equipment detection computations obtains mates with the total volume of predetermined battery, can be whether total volume is the same with the total volume size of predetermined battery, or whether difference is between the two within a predetermined threshold.

In a step 408, if testing result is coupling, be then predetermined battery by battery identification.

In step 409, after being predetermined battery by battery identification, predetermined charge voltages is adopted to carry out constant-voltage charge process to battery;

Electronic equipment, after being predetermined battery by battery identification, adopts predetermined charge voltages to carry out constant-voltage charge process to battery.Because battery identification is predetermined battery, then this battery can adopt predetermined charge voltages to carry out constant-voltage charge process to battery, if adopt standard charge voltage to carry out constant-voltage charge process to battery, then this battery cannot be full of electricity.

Such as, suppose that predetermined charge voltages is 4.35V, standard charge voltage is 4.2V, after being predetermined battery by battery identification, then carries out constant-voltage charge with the voltage of 4.35V to this battery; If charge to this battery with the voltage of 4.2V, then this battery cannot be full of electricity.

In step 410, by battery identification for after being not predetermined battery, adopt standard charge voltage to carry out constant-voltage charge process to battery.

Electronic equipment by battery identification for after being not predetermined battery, adopt standard charge voltage to carry out constant-voltage charge process to battery.Because battery identification is for being not predetermined battery, then this battery can not adopt predetermined charge voltages to carry out constant-voltage charge process to battery, because if adopt predetermined charge voltages to carry out constant-voltage charge process to this battery, by this battery of infringement, standard charge voltage is therefore adopted to carry out constant-voltage charge process to battery.
