Electric car electric high voltage safety interlock mechanism and control method, electric vehicles

The present invention provides a high voltage electric vehicle electrical safety interlock mechanism and a control method for an electric vehicle, said mechanism comprising: a vehicle control unit, a first low voltage relay collision switch, high-voltage relays, high voltage interlock with the connector , battery power system controller; vehicle controller are connected to a control terminal and a first low-power battery system controller relay; a first low-voltage relay, the load, the high voltage connector and the power battery system controller in turn connected to form a high-pressure safety an electrical interlock circuit; vehicle controller controls the first low voltage relay on / off driving voltage source, a high-pressure safety-off state is detected electrical interlock circuit, powered by the battery system voltage relay controller according to on and off states off. The present invention achieves monitoring and controlling pressure safety controller vehicle electrical interlock circuit, endangering personnel and vehicles to avoid runaway phenomenon, to improve the control performance of the vehicle, improving the reliability of operation of the vehicle.
