电动车辆
摘要：
本发明提供一种电动车辆，具备：系统主继电器，安装于将蓄电装置与驱动电路连接的动力用电力线上；电容器，安装于动力用电力线的系统主继电器和驱动电路之间；和充电用继电器，安装于将动力用电力线的系统主继电器和驱动电路之间与车辆侧连接部连接的充电用电力线上。并且，在利用来自直流充电站的电力对蓄电装置进行充电的过程中车辆侧连接部与站侧连接部的连接解除时，使充电用继电器和系统主继电器关断，使用电容器的电压对充电用继电器的两极熔敷异常进行诊断，并在该诊断之后将电容器放电。
摘要（英）：

A motor-driven vehicle includes a system main relay that is attached to a running electric power line connecting a power storage device to a drive circuit, a capacitor that is attached to the running electric power line between the system main relay and the drive circuit, and a charging relay that is attached to a charging electric power line connecting a vehicle-side connector to the running electric power line between the system main relay and the drive circuit. When a stand-side connector is disconnected from the vehicle-side connector while the power storage device is being charged with electric power from a direct-current charging stand, the charging relay and the system main relay are turned off, a two-pole welding abnormality of the charging relay is diagnosed using a voltage of the capacitor, and then the capacitor is discharged.
