The invention discloses a double-loop high-voltage interlocking device. The double-loop high-voltage interlocking device is provided with an alarm high-voltage interlocking loop, and two interlockingloops of the high-voltage interlocking loop are kept. The double-loop high-voltage interlocking device solves the problem that an existing high-voltage interlocking device of a new energy automobile cannot detect the loosening fault of a high-voltage interlocking loop wiring harness, meanwhile, the problems that the high-voltage interlocking device of the automobile is disconnected, the automobilecannot run normally and only can wait for rescue are solved, and the rescue time and cost of the automobile are saved.
本发明公开了一种双回路高压互锁装置。本发明的双回路高压互锁装置拥有报警高压互锁回路、保持高压互锁回路两条互锁回路。本发明的双回路高压互锁装置解决了现在的新能源汽车高压互锁装置不能检测高压互锁回路线束松动故障的问题,同时,预防车辆出现高压互锁装置出现断路,车辆无法正常行驶,只能够等待救援的问题,节约车辆救援的时间和费用。
