A vehicle includes a high-voltage system circuit including a high-voltage battery; a low-voltage system circuit including a low-voltage battery and an updater; a DC-DC converter coupled between the two circuits; and a controller that controls the two circuits and the DC-DC converter. The updater updates a program of an update-target device. The DC-DC converter reduces in voltage output electric power of the high-voltage battery and then supplies the electric power to the low-voltage system circuit. The controller determines whether the update-target device is a certain device relating to electric power supply from the high-voltage battery. If the update-target device is the certain device, the low-voltage battery is charged with the output electric power of the high-voltage battery, the certain device stops operating, and the updater updates the program of the certain device by using the output electric power of the low-voltage battery.
