Abstract
A vehicle power supply device which prevents a lack of power supply to the motor and insufficient recovery of regenerative electric power of the motor at the time of switching between power running and regeneration. First input-output sections () of a first DC-DC converter () are connected to second input-output sections () of a PDU (), second input-output sections () of the first DC-DC converter () are connected to a fuel cell () and a capacitor (), first input-output sections () of a second DC-DC converter () are connected to second input-output sections () of the PDU (), and second input-output sections () of the second DC-DC converter () are connected to a lithium-ion battery (). A voltage control means () places the first DC-DC converter () or the second DC-DC converter () in a direct connection state and controls an output voltage of the other DC-DC converter according to an output voltage of the DC-DC converter placed in the direct connection state during the power running of the motor () and during regeneration thereof.
