The invention relates to a fuse, a power-off control circuit, a power system and a vehicle. The fuse comprises a first trigger, a first trigger interface and a second trigger interface, the first trigger is electrically connected with the first trigger interface and the second trigger interface, the first trigger interface is used for being electrically connected with the airbag controller, and the second trigger interface is used for being electrically connected with the battery management controller; the first trigger comprises a first access end and a second access end which are connected in series with a power supply loop, and is used for controlling the power supply loop to be disconnected according to a first trigger signal sent by the airbag controller and/or a second trigger signal sent by the battery management controller. The first trigger can be triggered and controlled by the air bag controller and the battery management controller at the same time, the control modes are enriched, and the power-off control effect after the vehicle is collided can be improved.
本申请涉及一种熔断器、断电控制电路、动力系统及车辆,熔断器包括第一触发器、第一触发接口和第二触发接口;第一触发器分别与第一触发接口和第二触发接口电连接,第一触发接口用于与气囊控制器电连接,第二触发接口用于与电池管理控制器电连接;第一触发器包括用于串联在供电回路的第一接入端和第二接入端,用于根据气囊控制器发送的第一触发信号和/或电池管理控制器发送的第二触发信号控制供电回路断开。本申请使第一触发器能够同时受到气囊控制器和电池管理控制器的触发控制,丰富了控制方式,能够提高车辆在出现碰撞后的断电控制效果。
