VEHICLE CHARGING SYSTEM

A vehicle charge system (1) has a connection cable (2) to supply power from an outside power supply (9), such as a commercial power supply, a driving battery (4), an auxiliary battery (6), a driving battery charge apparatus (3), and an auxiliary battery charge apparatus (5). When a voltage across the auxiliary battery (6) is below a predetermined constant value, power from the outside power supply (9) is supplied to a control circuit (14) of the auxiliary battery charge apparatus (5), so that the auxiliary battery charge apparatus (5) charges the auxiliary battery (6) on its own without being controlled by a charge control portion (7).
