Abstract
A power supply device includes: a first high-voltage line for exchanging the electric power externally; a second high-voltage line for applying current flowing in a direction opposite to the first high-voltage line; a plurality of batteries; a plurality of SUs, the SUs being provided corresponding to the respective batteries, switching a connection state of the batteries to the first high-voltage line, and being disposed in a circle; and an SCU that controls the SUs. The SU can switch between a first state in which the battery corresponding to the SU is connected in series to the first high-voltage line and a second state in which the battery is not connected to the first high-voltage line. The SCU controls the SUs to switch to the first state or the second state in accordance with a voltage of the electric power to be charged and discharged.
