Abstract:
A plurality of driving circuits drive a plurality of contactors for connecting the battery pack and an external apparatus, respectively, based on a supply voltage. A processing circuitry control the plurality of driving circuits to sequentially close the plurality of contactors in a predetermined order, and check the supply voltage before closing each of the contactors.
