BALANCING APPARATUS, BALANCING METHOD, AND BATTERY MODULE |
摘要 |
According to an example embodiment, a balancing apparatus includes: bi-directional switches that are respectively connected to cells that are connected in series, a controller configured to measure voltages of the cells, and a multiwinding transformed connected to the bi-directional switches. The bi-directional switches are configured to control a flow of an electric current bi-directionally. The controller is configured to select a number of the cells for balancing based on the measured voltages of the cells. The controller is configured to turn on and turn off the bi-directional switches that are connected to selected cells based on the measured voltages. The multi-winding transformer is configured to transfer energy between the cells when the bi-directional switches connected to the selected cells are turned on. |
