Abstract:
An electricity storage device control system comprising a plurality of electricity storage devices and a plurality of charging circuits. The plurality of electricity storage devices are charged by a main power supply. The plurality of charging circuits are connected between the main power supply and the plurality of electricity storage devices. A connection state of the plurality of electricity storage devices being charged is switched to a first connection state or a second connection state on the basis of a voltage difference between an input voltage Vin of the main power supply and a charging voltage based on the voltage of each of the plurality of electricity storage devices. The first connection state is a connection state in which the plurality of electricity storage devices are connected in series, and the second connection state is a connection state in which the plurality of electricity storage devices are connected in parallel to the main power supply.
