Abstract
A system and method for monitoring the status of a system of battery strings is described. The system includes a current sensor for each of the battery strings, and a controller configured to compare the measured current with criteria to determine whether the battery is in a thermal runaway state. Prior to entering the thermal runaway state the battery current characteristics may indicate other less serious states. Warning messages are provided for selected events, and the battery string is disconnected from the remainder of the system when a thermal runaway state is encountered. The system may provide a local indication of status and may also interface with a communications network to provide for remote monitoring.
