A system in a vehicle includes two or more modules. Each of the two or more modules includes battery cell groups. The battery cell groups of the two or more modules provide propulsion power for the vehicle. The two or more modules also include a voltage sensor to measure a voltage output by the battery cell groups 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 an infrared radiation profile within the module. The system also includes 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 the voltage, the temperature, the hydrogen level, or the infrared radiation profile for the one of the two or more modules.
