The invention provides a vehicle-electricity separation system, a vehicle-electricity separation control method and a vehicle, and relates to the technical field of vehicle safety. The vehicle-electricity separation system comprises a vehicle body controller, a sensing device, a vehicle-electricity separation switch and an electromagnetic connecting device, and the electromagnetic connecting device is used for connecting a power battery to a vehicle body; the sensing device is used for detecting the state of the power battery; the vehicle body controller is used for judging whether the power battery is in an abnormal state or not according to a detection signal of the sensing device; when the power battery is in an abnormal state, the vehicle-electricity separating switch is used for controlling the electromagnetic connecting device so that the power battery can be separated from the vehicle body. When the power battery is in a fire state and the like, the power battery and the vehicle body can be directly disconnected through the electromagnetic connecting device, so that the electromagnetic connecting device does not provide electromagnetic connecting force between the power battery and the vehicle body any more, the fire of the whole vehicle is avoided, and the safety of the vehicle is improved.

    本发明提供了一种车电分离系统、车电分离控制方法及车辆,涉及汽车安全技术领域。本发明的车电分离系统,包括车身控制器、传感装置、车电分离开关和电磁连接装置,所述电磁连接装置用于使动力电池连接于车身;所述传感装置用于检测所述动力电池的状态;所述车身控制器用于根据所述传感装置的检测信号判断所述动力电池是否处于异常状态;当所述动力电池处于异常状态时,所述车电分离开关用于控制所述电磁连接装置以使所述动力电池与所述车身分离。本发明在动力电池处于起火等状态时,可以通过电磁连接装置直接断开动力电池与车身的连接,使电磁连接装置不再提供动力电池与车身间的电磁连接力,规避整车起火,从而提高了车辆的安全性。
