The same kind of electrical appliances in fig. 1 only represent the same power supply, and do not represent the same fuse. After the VCU detects the rifle signal of inserting of rifle that charges, the control driving charging interlocking relay is closed, and the power supply of disconnection ignition switch prevents to drive when inserting the rifle, and VCU will control closed ACC relay simultaneously to satisfy the supply of ACC power when charging.
