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.
