A power supply apparatus for a vehicle includes first and second batteries (B1, B2) provided electrically in parallel to main loads (14, 22), a boost converter (12A) provided between the first battery (B1) and the main loads, a boost converter (12B) provided between the second battery (B2) and the main loads, an auxiliary battery (B3), a DC/DC converter (33), and an auxiliary load (35) driven by power from the auxiliary battery (B3) or DC/DC converter (33). The controller (30) determines charging currents or discharging currents for the batteries (B1, B2) reflecting variations in a current flowing through the auxiliary load (35). Accordingly, a power supply apparatus for a vehicle can thus be provided in which imbalance between charging/discharging currents for a plurality of power storage devices is reduced.
