VEHICLE

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 high-voltage system circuit and the low-voltage system circuit, and a controller. The low-voltage battery has a lower output voltage than the high-voltage battery. The updater updates a program of an update-target device with electric power supplied from the low-voltage or high-voltage battery. The DC-DC converter is capable of reducing in voltage output electric power of the high-voltage battery and then supplying the electric power to the updater. The controller sets a target SOC range of the high-voltage battery and controls charging of the high-voltage battery based on the target SOC range. The controller changes a target SOC lower-limit value of the high-voltage battery to a value higher than a normal value when updating of the program of the update-target device is scheduled.
