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:
