<p>A power supply apparatus for a vehicle (100) includes first and second batteries (BA, BB), a power supply line (PL2), first and second boost converters (12A, 12B), a system main relay (SMR4), a capacitor (C2), and a control device (30) controlling the first and second boost converters (12A, 12B) and a connecting portion. Upon receiving a startup instruction IGON, the control device (30) controls the first boost converter (12A) such that a feeding node capacitor (CH) is charged from the first battery (BA), and controls the second boost converter (12B) such that the capacitor (C2) is charged from the power supply line (PL2). After the charging of the capacitor (C2) is completed, the control device (30) switches the system main relay (SMR4) from a disconnected state to a connected state.</p> |
