The invention discloses a high-voltage interlocking control system of a pure electric vehicle, which comprises a plurality of high-voltage devices and control units thereof, and the control unit of each high-voltage device correspondingly detects an interlocking connection fault through a detection circuit, and judges whether the interlocking fault occurs or not according to the detected state; the output end of each high-voltage device is connected to a VCU, and the VCU sends out a reminding alarm according to a fault signal transmitted by the control unit of each high-voltage device. The system has the advantages that the control units of the high-voltage devices are used for detecting respective interlocking state data, detecting and uploading the interlocking state data to the VCU, and the VCU performs unified judgment and alarm reminding, so that the cost of the whole vehicle can be saved, the increase of wiring is reduced, the space of the whole vehicle is saved, and the position of a fault can be quickly determined by the VCU.

    本发明公开了一种纯电动汽车高压互锁控制系统,包括多个高压器件及其控制单元,每个所述的高压器件的控制单元对应的通过检测电路来检测其互锁连接故障,并根据检测的状态判断互锁故障与否,每个所述的高压器件的输出端连接至VCU,所述VCU根据各个高压器件的控制单元传来的故障信号来发出提醒报警。本发明的优点在于:采用各高压器件的控制单元检测各自的互锁状态数据并进行检测上传至VCU中由VCU统一判断报警提醒,可以节约整车成本,减少布线的增加、节省整车的空间,且可以快速的由VCU确定故障的位置。
