PROCÉDÉ DE CHARGE RAPIDE POUR BATTERIE, DISPOSITIF DE CHARGE, DISPOSITIF À CHARGER ET SYSTÈME DE CHARGE

摘要

Provided are a battery quick charging method, a charging apparatus, a device to-be-charged, and a charging system. 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. As such, the constant-current charging in which a large current is applied can be prolonged, thereby increasing the charging speed. In addition, the charging cut-off voltage can be flexibly adjusted according to the temperature of the battery, which is possible to avoid damage of the battery due to overvoltage while ensuring that the battery will be fully charged.
