A charging system includes: a main battery storing electric power for a vehicle to travel; an inlet connected to a charging connector; a charging relay that switches a path of electric power from the inlet to the main battery; a converter that steps down a voltage of the electric power from the inlet; and an ECU that controls the charging relay and the converter. The ECU: controls the converter so that the converter starts stepping down the voltage of the electric power from the inlet to the auxiliary voltage after receiving the electric power from the inlet; supplies, before the charging relay switches to the connected state, the charging relay with the electric power from the converter as operating power for switching to the connected state; and controls the charging relay so that the charging relay switches from the disconnected state to the connected state, using the operating power.
