Abstract:
1. An electric vehicle comprising: a main battery; a charging system electronic device configured to charge a vehicle-mounted electric power supply that includes the main battery; an electrically powered system-based electronic device including an inverter configured to convert direct-current power of the main battery into alternating-current power, thereby driving a motor for travelling; a first high-voltage electric wire that connects the charging system electronic device and the electrically powered system-based electronic device to any one of the positive electrode side and the negative electrode side of the main battery; and a second high-voltage electric wire that connects the charging system electronic device and the electrically powered system-based electronic device to the other one of the positive electrode side and the negative electrode side of the main battery, characterized by the electrically powered system-based electronic device and the charging system electronic device are sequentially disposed in parallel, the electric vehicle further comprises: the first junction relay is disposed between the main battery and the charging system electronic device, and a first pre-charge relay that bypasses the first junction relay is disposed in parallel with the first junction relay, and the second junction relay is disposed between the charging system electronic device and the electrically powered system-based electronic device.
