Abstract:
A charging method and a charger. The method is suitable for charging a battery (30) using different types of power adapters (10), comprising: acquiring the working state of a present power adapter connected to the charger (20) by means of a physical interface; if the working state of the present power adapter is an over-current protection state, continuing to supply power to a charging control unit (204) of the charger by means of a backup power supply built in the charger (203); and reducing, by means of the charging control unit, the present current outputted by the charger to the battery until the working state of the present power adapter returns to a normal state. The charging method can supply, when the present power adapter is in an over-current protection state, power to the charging control unit of the charger by means of the backup power supply built in the charger, so as to reduce the present current outputted by the charger to the battery, thereby enabling various types of power adapters to normally charge the battery, being more universal.
