A charging method for a battery pack includes sending, by a battery management module of the battery pack, a charging request for a first current to a charging pile for charging, controlling, by the battery management module in response to determining that first-current charging of the battery pack meets a first predetermined condition, the battery pack to perform pulse discharge, and controlling, by the battery management module in response to determining that the pulse discharge of the battery pack meets a second predetermined condition, the battery pack to stop discharging, and sending a charging request for a second current to the charging pile for charging. The second current is less than the first current.
