一、纯电动汽车电气系统安全分析 纯电动轿车电气系统主要包括低压电气系统、高压电气系统及 CAN 通讯信息网络系统。 1、低压电气系统采用 12 V 供电系统，除了为灯光照明系统、娱乐系统及雨刷器等常规低压用电器供电外，还为整车控制器、电池管理系统、电机控制器、DC/DC 转换器及电动空调等高压附件设备控制回路供电； 2、高压电气系统主要包括动力电池组、电驱动系统、DC/DC 电压转换器、电动空调、...
高压直流继电器，原本主要在电力行业以及航空、航天行业应用。近年来电动汽车逐渐兴起，驱动配电系统，成了高压直流继电器一个非常重要的应用场景。高压是相对于24V、48V低压系统而言。低速电动车有些选择60V和72V系统的电源配置，一般高速乘用车电压都在200V以上，大巴更是可以达到600V以上。满足这个电压阶段使用要求的继电器，被称为高压直流继电器。 高压直流继电器，寿命包括机械寿命和电寿命两个参数。...
