A power unit of an electric vehicle may be connected to a main battery, an AC inlet, and a DC inlet. The power unit may include a battery connector to which a battery power cable is connected, an AC inlet connector to which an AC inlet power cable is connected, and a DC inlet connector to which a DC inlet power cable is connected. The battery connector may be closer to the main battery than a center of the power unit is to the main battery. The AC inlet connector may be closer to the AC inlet than the center of the power unit is to the AC inlet. The DC inlet connector may be closer to the DC inlet than the center of the power unit is to the DC inlet.
