Abstract
A charging control method for a battery pack at least including two batteries connected in parallel. The method includes determining, based on a charging parameter, states of charge (SOCs) corresponding respectively to the batteries at elapsing of a preset charging time, calculating, according to the SOCs, an amount of charge transfer between the batteries after stopping charging at the elapsing of the preset charging time, judging whether a charge-receiving battery is in a critical overcharge state according to the amount of charge transfer, and, in response to the charge-receiving battery being in the critical overcharge state, stopping charging the battery pack at the elapsing of the preset charging time.
