Abstract
A vehicle power-supply unit includes a high-voltage battery, a low-voltage battery having a lower voltage than the high-voltage battery, and an inlet, and is capable of connecting a feed connector of an external power source to the inlet and supplying electric power from the external power source to a charge target which is at least one of the high-voltage battery and the low-voltage battery. The power-supply unit includes: charge control means that controls charging of the charge target; and a battery voltage sensor that detects a voltage of the low-voltage battery. If a low-voltage battery voltage value VL becomes not higher than a charge abort threshold Vabort while connecting the feed connector to the inlet and supplying electric power from the external power source to the charge target, the charge control means stops supply of electric power from the external power source to the charge target.
