The invention discloses an electric vehicle high-voltage interlocking safety system which comprises a vehicle control unit VCU, and the vehicle control unit VCU serves as a center and is connected with a first high-voltage interlocking loop and a second high-voltage interlocking loop. High-voltage devices related to driving safety in the first high-voltage interlocking loop connection system comprise but not limited to interfaces of a driving motor, a steering oil pump and a brake air pump, and high-voltage devices related to non-driving safety in the second high-voltage interlocking loop connection system comprise but not limited to interfaces of a charging system, a DCDC system, an air conditioner compressor and a PTC. The first high-voltage interlocking loop monitors the interlocking state of high-voltage devices related to driving safety in the electric vehicle, and the second high-voltage interlocking loop monitors the interlocking state of high-voltage devices related to non-driving safety in the electric vehicle.
