A system in a vehicle includes two or more modules. Each of the two or more modules includes a group of battery cells. The battery cell groups of the two or more modules provide propulsion power for the vehicle. The two or more modules further include a voltage sensor to measure a voltage output by the battery cell pack of the module, a temperature sensor arranged to measure a temperature within the module, a gas sensor arranged to sense a hydrogen level within the module, and an infrared sensor positioned to obtain a distribution of infrared radiation within the module. The system further comprises two or more relays, one of the two or more relays being arranged to electrically isolate one of the two or more modules based on a voltage, temperature, hydrogen level, or infrared radiation profile of the one of the two or more modules.
车辆中的系统包括两个或更多模组。两个或更多个模组中的每一个都包括电池单体组。两个或更多个模组的电池单体组为车辆提供推进动力。两个或更多个模组还包括测量模组的电池单体组输出的电压的电压传感器、设置成测量模组内的温度的温度传感器、设置成感测模组内的氢水平的气体传感器、以及定位成获得模组内的红外辐射分布的红外传感器。该系统还包括两个或更多个继电器,两个或更多个继电器中的一个继电器被布置成基于两个或更多个模组中的一个模组的电压、温度、氢水平或红外辐射分布来电隔离该两个或更多个模组中的一个模组。
