A battery system includes first and second battery packs connected to positive and negative DC voltage bus rails, a contactor switch connected between the battery packs, a solid-state switch in serieswith the contactor switch, and a controller. The controller determines characteristic values of the switches, including a respective temperature, voltage, and current value for each. The controller also detects a predetermined electrical fault condition of the contactor switch using the characteristic values, and executes a control action in response to the electrical fault condition. The controlaction includes opening the semi-conductor switch to thereby interrupt a flow of current between the first and second battery packs. A mobile platform includes road wheels connected to a body, a rotary electric machine configured to power the road wheels and thereby propel the mobile platform, and the battery pack, switches, and controller.
本发明涉及一种电池系统,该电池系统包括:连接到正和负DC电压总线轨的第一电池组和第二电池组;连接在电池组之间的接触器开关;与接触器开关串联的固态开关;以及控制器。控制器确定开关的特征值,包括针对每个开关的相应温度、电压和电流值。控制器还使用特征值来检测接触器开关的预定电气故障状况,并响应于电气故障状况执行控制动作。控制动作包括打开半导体开关,从而中断第一电池组与第二电池组之间的电流流动。移动平台包括:连接到主体的车轮;被配置为向车轮提供动力并由此推进移动平台的旋转电机;以及电池组;开关;和控制器。
