In step s 12, when the voltage of the battery is equal to predeterminated voltage, the charging current is reduced.
Fig. 4 is a kind of connection relationship diagram of battery shown according to an exemplary embodiment.In one embodiment,
As shown in figure 4, charging management chip (also referred to as power management chip) is connected to the encapsulation (Pack) of battery, pass through Charge Management
Chip can control charging current and charging voltage.
Wherein, the resistance of battery core is R3, and the resistance of circuit is R1, battery between anode and charging management chip anode
The resistance of circuit is R2 between cathode and charging management chip cathode.Generally will encapsulation anode Pack+ and encapsulate cathode Pack- it
Between voltage as the voltage of battery namely voltage=(R1+R2+R3) × charging current of battery, accordingly, determine charging electricity
