A charging system (11) includes: a main battery (4) that stores electric power for vehicle traveling; an inlet (1) connected to the charging connector (910); a charging relay (31) that switches a path of power from the inlet to the main battery; a converter (25) for reducing the voltage of the power from the inlet; and an ECU (10) that controls the charging relay and the converter. The ECU: controls the converter such that the converter begins to step down the voltage of the power from the inlet to the auxiliary voltage after receiving the power from the inlet (steps S114, S124); supplying power from the converter to the charging relay as operating power for switching to the connected state before the charging relay is switched to the connected state (steps S114, S124); and controls the charging relay such that the charging relay switches from an off state to a connected state using the operating power (steps S117, S127).

    充电系统(11)包括:主电池(4),其储存用于车辆行驶的电力;入口(1),其连接至充电连接器(910);充电继电器(31),其切换从入口到主电池的电力的路径;转换器(25),其对来自入口的电力的电压进行降压;以及ECU(10),其控制充电继电器和转换器。ECU:控制转换器,使得转换器在从入口接收到电力之后开始将来自入口的电力的电压降压至辅助电压(步骤S114、S124);在充电继电器切换至连接状态之前,将来自转换器的电力供应给充电继电器作为用于切换至连接状态的操作电力(步骤S114、S124);并且控制充电继电器,使得充电继电器使用操作电力从断开状态切换至连接状态(步骤S117、S127)。
