The voltage that voltage versus cell BAT when battery BAT enters overcharging state enters when filling full state is higher by 0.1V- 0.6V。

In some possible embodiments, as shown in Figure 3 and Figure 5, terminal VC is used to pass through resistance R15 connection battery BAT Anode.

If the voltage of 110 detection terminal VC of sensing control circuit is less than over-discharge voltage, the state of battery BAT is over-discharge state；If The voltage of 110 detection terminal VC of sensing control circuit is not less than over-discharge voltage and is less than saturation voltage, and the state of battery BAT is normal shape State；If the voltage of 110 detection terminal VC of sensing control circuit is not less than saturation voltage and is less than overcharged voltage, the state of battery BAT is Saturation state；If the voltage of 110 detection terminal VC of sensing control circuit is not less than overcharged voltage, the state of battery BAT is to overcharge shape State；The high 0.1V-0.6V of the more saturated voltage of overcharged voltage.Wherein, over-discharge voltage, saturation voltage, overcharged voltage can be according to specific institutes It is formulated with the characteristic of battery BAT.

Sensing control circuit 110 is according to the connection or disconnection between the state control terminal VE and terminal VB of battery BAT, and control Connection or disconnection between terminal VS and terminals P G processed.
