针对纯电动汽车高压回路的安全监控问题,对纯电动汽车高压回路的配置、绝缘检测、预充电、高低压保护、高压环路互锁等方面进行了研究,对纯电动汽车驻停过程中高压回路的故障诊断与安全控制策略进行了归纳,提出了一种基于STM32 ARM Cortex-M3内核单片机以及CAN总线技术的监测系统,利用高压直流试验台对纯电动汽车的绝缘电阻以及发生故障时高压断路响应时间进行了测试。研究结果表明,该系统能实时监测高压系统的各项电气参数,能够实现绝缘检测、预充电、高低压保护、高压环路互锁等多项功能,系统故障断路响应迅速、可靠性高。
Aiming at realizing high voltage safety circuit monitoring of the pure electric vehicle, insulation monitoring, pre-charging, high ＆ low voltage protection and high voltage interlocking of the high voltage circuit were researched, and the monitoring system based on STM32 ARM Cotex-M3 and CAN bus technology was proposed. The insulation resistance and the failure cut response time of high voltage system were tested by using high voltage DC test rig. The results indicate that the system can real-timely monitor the electrical parameters of the high-vohage, realize the function of insulation monitoring, pre-charging, high ＆ low voltage protection and high voltage interlocking, and it has fast response and high reliability.
