Closing at above-mentioned switch K3, charging chip 1 or charging chip 2 detect that the voltage of rechargeable battery is close to full state
Time, such as when reaching 95% more than (or other ratio, such as 70% etc.), notify main control chip；Main control chip controls integrated
K1 or K2 of on-off circuit disconnects, and retains a charging chip (i.e. charging chip 1 or 2) and continues charging, until battery is full of.
If connected to mobile terminal charge power supply power is smaller, it is impossible to meet the start requirement of mobile terminal, then when
Main control chip by testing circuit judge charge power supply export electric current can not meet the start of mobile terminal require time, by always
K2, K3 switch Guan Bi of line traffic control integrated switching circuit, K1 disconnects, charging chip 2 is charged battery；Or by total
K1, K3 switch Guan Bi of line traffic control integrated switching circuit, K2 disconnects, charging chip 1 is charged now to battery, with existing
The mode of operation of charging current is essentially identical.
