The invention provides a pure electric vehicle high-voltage interlocking control system and method. The pure electric vehicle high-voltage interlocking control system comprises a VCU high-voltage interlocking loop 1, and the VCU high-voltage interlocking loop 1 comprises a DC/DC converter, a high-voltage input and output line connector of a DC/AC converter, a steering oil pump motor and an input connector of an air compressor; the system further comprises a VCU high-voltage interlocking loop 2 which comprises a high-voltage connector, an air conditioner compressor input connector and a PTC input connector, and the high-voltage connector is used for outputting high-voltage power to an air conditioner compressor and a PTC by a high-voltage distribution box; the system further comprises a VCUhigh-voltage interlocking loop 3 which comprises a high-voltage box and a battery pack cover opening detector. According to the invention, the conventional mode of acquiring the high-voltage interlocking signal of the whole system only through the VCU is changed into a plurality of high-voltage interlocking loops, so that the driving experience of a driver can be improved, the calculation redundancy of the VCU is reduced, and meanwhile, troubleshooting and overhauling of faults are facilitated.

    本发明提供了一种纯电动汽车高压互锁控制系统及方法,包括VCU高压互锁回路1,VCU高压互锁回路1包括DC/DC转换器、DC/AC转换器的高压输入和输出线接插件以及转向油泵电机、空压机的输入接插件;还包括VCU高压互锁回路2,VCU高压互锁回路2包括高压配电盒输出到空调压缩机、PTC的高压接插件以及空调压缩机输入接插件、PTC输入接插件;还包括VCU高压互锁回路3,VCU高压互锁回路3包括高压盒以及电池包开盖检测;本发明将现有的仅通过VCU对整个系统的高压互锁信号进行采集的方式更改为多个高压互锁回路,能够提高驾驶人员的驾驶体验,减小VCU计算冗余度,同时还有利于故障的排查、检修。
