Abstract: A charging control method includes the following. (a) An electrical state of a battery set is obtained. (b) Whether the electrical state is greater than a first electrical state threshold is determined and charging control based on a first charging mode or a second charging mode on the battery set is performed accordingly. (c) During the charging control on the battery set, at least one temperature difference value is determined based on temperature values of the battery set at different times.
