The invention discloses a high-voltage interlocking system, a high-voltage interlocking detection method and a vehicle. The high-voltage interlocking system comprises a plurality of high-voltage interlocking loops and a controller, and the high-voltage interlocking loops are connected in parallel and connected with the controller in series. Each high-voltage interlocking loop comprises at least one high-voltage load; the plurality of high voltage interlock loops includes a power battery interlock loop, a charging interlock loop, a drive interlock loop, a high voltage accessory interlock loop, and a thermal management interlock loop. According to the scheme, when the high-voltage interlocking system has the interlocking fault, the high-voltage interlocking loop with the fault can be accurately identified, so that the troubleshooting range is narrowed, the troubleshooting efficiency is improved, and the timeliness and the accuracy of positioning the interlocking fault position are improved; moreover, the high-voltage interlocking loops are mutually independent, the execution of the functions of the high-voltage interlocking loops cannot be affected by interlocking faults of other interlocking loops, and the high-voltage interlocking detection of the whole vehicle can be safely and reliably realized.
本发明公开了一种高压互锁系统、高压互锁检测方法及车辆。高压互锁系统包括多个高压互锁回路以及控制器,多个高压互锁回路相互并联,并分别与控制器串联;各高压互锁回路中包括至少一个高压负载;多个高压互锁回路包括动力电池互锁回路、充电互锁回路、驱动互锁回路、高压附件互锁回路以及热管理互锁回路。通过上述方案,在高压互锁系统出现互锁故障时,可准确识别存在故障的高压互锁回路,从而缩小排查范围,提高排查效率,提升互锁故障位置定位的及时性以及准确性;且各高压互锁回路相互独立,不会因为其他互锁回路的互锁故障影响自身功能的执行,能够安全可靠地实现整车高压互锁检测。
