Control system of electric vehicle and electric vehicle

The invention provides a control system of an electric vehicle and the electric vehicle. The control system comprises a power battery, a main relay, a battery management system, a control switch, and a vehicle control unit. The main relay is arranged between the power battery and a high-voltage bus. The battery management system is connected with the control end of the main relay. The battery management system is used to control on-off of the main relay when the battery management system is in a normal state. One end of the control switch is connected with the control end of the main relay, and the other end of the control switch is connected with constant electricity. The vehicle control unit is connected with the control end of the control switch, and the vehicle control unit is used to control on off of the main relay through the control switch when the battery management system breaks down. The main relay can be controlled by the battery management system and the vehicle control unit, so as to ensure completeness of functions of the battery management system, and high-voltage electrifying can be completed through the vehicle control unit when the battery management system breaks down, thereby ensuring a vehicle to continuously run.
