The vehicle-to-vehicle charging circuit is applied to a first electric vehicle including a first charging interface, and the vehicle-to-vehicle charging circuit includes a controller, a power supply circuit and a voltage detection circuit. The voltage detection circuit can collect the voltage at the charging confirmation terminal in the first charging interface, and the controller can control the power supply circuit to pass through the first charging interface when it is determined based on the voltage that the first charging interface is connected to the vehicle-to-vehicle charging harness. The DC power supply terminal of the vehicle is charged to the second electric vehicle connected to the vehicle-to-vehicle charging harness. That is, one electric vehicle can be used for vehicle-to-vehicle charging to another electric vehicle to be charged without moving the electric vehicle to be charged to a charging pile for charging, which improves the flexibility of charging the electric vehicle.
