BATTERY QUICK CHARGING METHOD, DEVICE TO-BE-CHARGED, CHARGING APPARATUS

Provided are a battery quick charging method, a charging apparatus, and a device to-be-charged. The battery quick charging method includes the following. State parameters of a battery of a device to-be-charged are acquired, where the state parameters of the battery include a present temperature of the battery. A charging cut-off voltage corresponding to the present temperature is selected from a target parameter mapping relationship, where the charging cut-off voltage is higher than a rated voltage of the battery. Constant-current charging is performed on the battery until a voltage of the battery reaches the charging cut-off voltage and then performing of the constant-current charging on the battery is stopped.
