Abstract
The utility model discloses a power supply circuit of an electric automobile and an AC charging vehicle control device of the electric automobile. The circuit comprises a CC signal detection amplification circuit, a relay, and a relay control circuit used for controlling the relay. A CC signal of a charging plug of the automobile is amplified through the CC signal detection amplification circuit, so as to drive the relay contact to be connected to the power supply end of a vehicle control device. The relay is used for controlling the circuit to carry out self-locking energization. When the vehicle charging plug is detected to be disconnected, the relay control circuit is cut off to stop charging.
