摘要:A control device determines that a system relay for precharging is weldedwhen, after generation of a signal at the H level upon starting of a vehicle system to turnon only a cathode-side system relay, a precharge current is at least a reference value.When it is determined that the system relay for precharging is welded, the control device
immediately turns off the cathode-side system relay without determining welding ofcathode-side and anode-side system relays and performs discharging of a capacitor. Inthis situation, the control device determines welding of the cathode-side system relaybased on a voltage between both ends of the capacitor. When it is determined that thesystem relay for precharging is not welded, welding of the cathode-side and anode-sidesystem relays is determined upon termination of the vehicle system.
