Abstract: A charging method for a battery set with a plurality of battery cells, having steps of performing a serial charging on the battery cells; determining whether one of the battery cells reaches a saturation voltage; and performing a uniform separately charging on the battery cells when one of the battery cells reaches the saturation voltage, wherein the uniform separately charging comprises sorting the battery cells according to cell voltages of the battery cells; and sequentially and separately charging the sorted battery cells to a Nth segmented voltage in a Nth segmentation, wherein N is a positive integer from 1 to K, and K is a positive integer larger than 1. The charging method of the present disclosure can reduce the temperature rising of the battery cell due to the longtime charging.

Abstract: An electrical system having a master node, at least one slave node and a bus linked to both of the master node and the slave node is illustrated. The master node check whether a reception register of the slave node does not receives a new data for a first time period, and resets the slave node while the reception register of the slave node does not receives the new data for the first time period; and the slave node checks whether the reception register of the slave node does not receives the new data for a second time period, and resets the slave node itself while the reception register of the slave node does not receives the new data for the second time period. Therefore, the communication stability of the electrical system can be enhanced.

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.
