The invention provides an electric vehicle high-voltage distribution box relay monitoring system and method. A voltage detection module is additionally arranged in a high-voltage distribution box, therelay actuation and disconnection information is sent to the vehicle control unit, each state of the relay is detected and judged in real time in a power-on state, a power-off state and a normal state, the fault state and the normal state are outputted, and the working normality of the high-voltage distribution box of the electric vehicle is ensured in time; when a problem occurs, the problem canbe reported to the driver as soon as possible, the driver is reminded to contact related workers as soon as possible for maintenance, the operation states of other related high-voltage parts on the automobile can be monitored at the highest speed, timely maintenance is carried out after the relay is damaged, the safety of the electric automobile power distribution device is improved to a greaterextent, and thus the risk of the safety of the whole electric automobile is reduced.

    本发明提出的一种电动汽车高压配电箱继电器监控系统及方法,通过在高压配电箱内部添加电压检测模块,将继电器吸合以及断开信息发送到整车控制器,通过在上下电以及正常状态下,对于继电器的各个状态进行实时检测以及判断,以及对于故障状态及正常状态的输出,及时保障了电动汽车高压配电箱工作的正常性,在出现问题时可以最快的报告给驾驶人员,以提醒司机尽快联系相关工作人员尽快检修,可以最快的速度监测到车辆上的其他涉及到的高压件的运行状态,在对继电器产生伤害后进行及时的检修,在更大程度上提高了电动汽车配电装置的安全性,从而降低了电动汽车整车安全的风险。
