| description | The invention discloses an electric vehicle collision protection system, and belongs to the technical field of electric vehicles. The system comprises an air bag controller which is used for responding to detected automobile collision, sending a first collision signal to a vehicle control unit through a hard wire and sending a second collision signal to the vehicle control unit, a battery management system controller and a motor controller through a CAN bus; the vehicle control unit is used for responding to the first collision signal and sending the first collision signal to the battery management system controller and the motor controller through a hard wire; the battery management system controller is used for responding to the first collision signal and controlling the battery to be powered off under the condition that the second collision signal is abnormal; and the motor controller is used for responding to the first collision signal and controlling the motor to enter a voltage reduction mode under the |
