When pressure is more than preset threshold, so that it may the charging current to charge the battery are increased to maximum charging current, battery is at this time
Constant-current charge state.In this state, charging equipment can charge the battery according to maximum charging current, realize constant-current charge.Together
When, during constant-current charge, the speed to charge the battery is also most fast.
Wherein, predetermined voltage threshold judge battery be precharging state or be constant-current charge state judgment criteria, should
Predetermined voltage threshold can be 3V, and the embodiment of the present invention is without limitation.
Specifically, charging equipment can determine whether the battery when charging equipment receives the cell voltage of mobile terminal transmission
Range locating for voltage:
Charging equipment determines the tool of the current charged state of the mobile terminal according to the cell voltage that the battery information includes
Body mode can be with are as follows:
When the cell voltage is equal to maximum battery voltage, charging equipment can determine whether the current charged state of the mobile terminal
