Disclosed is a power control device for vehicle. According to the present invention, the power control device for vehicle includes: a photovoltaic module; a bidirectional converter which bidirectionally transmits the power of a low voltage battery and the power of a high voltage battery; a common bidirectional converter which transmits power generated in the photovoltaic module to a low voltage battery or bidirectionally transmits the power of the low voltage battery and the power of the high voltage battery; a switching module which connects the common bidirectional converter with the bidirectional converter or connects the photovoltaic module with the common bidirectional converter; and a control unit which controls power transmission between the low voltage battery and the high voltage battery by connecting the common bidirectional converter with the bidirectional converter through a switching module according to operation modes or transmits power generated in the photovoltaic module to the low voltage battery by connecting the photovoltaic module with the common bidirectional converter through the switching module. The present invention is able to reduce the volume, weight, and manufacturing cost of the power control device.
