The invention relates to the technical field of electromobiles, in particular to a collision power-off protection system of an electromobile. The system comprises a battery management unit, a power battery pack, a finished automobile control unit, an airbag controller, an automobile body collision sensor and an automobile body controller, wherein the battery management unit, the finished automobile control unit, the airbag controller and the automobile body controller are connected via a CAN (Controller Area Network) bus; the airbag controller is further connected with the battery management unit and the automobile body controller via wires; the airbag controller is connected with the automobile body collision sensor via a wire; and the battery management unit is connected with the power battery pack via a wire. The battery management unit, the finished automobile control unit and the automobile body controller of the system can simultaneously receive three types of signals emitted by an airbag, i.e., a CAN signal, a wire current signal and a radio signal. When any signal is received, the control units related to collision can implement passive safety protection measures of a vehicle, and the collision power-off reliability and stability are improved.
