Zusammenfassung:	A power supply device for a vehicle improves the power performance of the vehicle. The present invention is provided with: a battery pack provided with battery stacks (A, B) connected in parallel to each other; a switch (SWa) that is controlled to be in an ON state in which the battery stack (A) and the inverter (18) are connected and an OFF state in which the battery stack (A) and the inverter (18) are separated; a switch (SWb) that is controlled to be in an ON state in which the battery stack (B) and the inverter (18) are connected and an OFF state in which the battery stack (B) and the inverter (18) are separated; an output determination unit that determines whether the state of the battery stacks (A, B) is a first output state or a second output state that is higher than the first output state; and a switch control unit for controlling the switches (SWa, SWb), the switch control unit controlling one of the switches (SWa, SWb) to an ON state and the other of the switches (SWa, SWb) to an OFF state when at
