The re-distribution switch is coupled between a ground and a common terminal of the other terminal of the first winding of N transformers to supply the charge of N batteries to the first winding of N transformers. N first semiconductor switching devices are coupled between a second winding of N transformers and a positive electrode of the battery. The voltage detection and driving signal generation unit detects a voltage of N batteries, and generates a driving signal for driving the re-distribution switch and the charging/discharging control switching unit in response to a detected voltage.
