    Abstract: A battery active-balancing system comprises an external balancing power; a buck converter having a first side-winding and a second side-winding induced thereby, the first side-winding and the second side-winding each having a positive terminal and a negative terminal; a battery comprising series-connected cell-units each having a positive terminal and a negative terminal; a cell voltage-sensing unit coupled to the battery to sense a voltage of each cell unit of the series-connected cell-units; a main switch component coupled to the first side-winding and the battery in an ON state, or coupled to the first side-winding and the external balancing power in an OFF state; a cell-switch unit comprising first cell-switch components and second cell-switch components, wherein each of the first cell-switch components is coupled to the positive terminal of corresponding one cell-unit and the positive terminal of the second side-winding, and each of the second cell-switch components is coupled to the negative terminal of corresponding one cell-unit and the negative terminal of the second side-winding; and a microcontroller for controlling the main switch component and the cell-switch unit, and determining a voltage level fed back from the cell voltage-sensing unit.

    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.
