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. (d) Whether the temperature difference value is greater than a first temperature difference threshold is determined and whether to temporarily stop or continue the charging is determined accordingly. (e) During the charging control on the battery set, the electrical state is obtained, and whether the electrical state satisfies a fully-charged criterion is determined and whether to stop or continue the charging control is determined accordingly.

Abstract: Electric vehicle range extending apparatus includes a step-down voltage provision unit, cell voltage sensing unit, cell switching unit, and control unit. The step-down voltage provision unit has an input port to be coupled to the main battery pack or an auxiliary battery pack, and an output port to output a power balancing signal. The cell voltage sensing unit is for being coupled to the battery cells and sensing individual voltages of the battery cells. The cell switching unit, including a plurality of switches, is coupled to the battery cells respectively, and coupled to the output port. The control unit, coupled to the cell voltage sensing unit, step-down voltage provision unit, and cell switching unit, is for controlling the cell switching unit based on the individual voltages of the battery cells so as to apply the power balancing signal to at least one of the battery cells selectively.
