A system and method determine (a) thermal characteristics of an energy storage apparatus that supplies electric current to one or more vehicular loads for powering the one or more vehicular loads and/or (b) electrical characteristics of the energy storage apparatus or the one or more vehicular loads. The system and method determine whether operation of the energy storage apparatus indicates that the energy storage apparatus is unexpectedly heating or unexpectedly cooling and identifying a fault in the energy storage apparatus responsive to determining that the energy storage apparatus is unexpectedly heating or unexpectedly cooling.

Monitoring system for an energy storage apparatus

A ground impedance and fault detection system may include a controller that can identify a location of a ground fault in a circuit. The circuit also may include one or more positive contactors connected with a positive portion of the bus between battery strings and a load and a negative bus contactor coupled with a negative portion of the bus between the battery strings and the loads. The controller may identify the ground fault by opening the one or more positive contactors and closing the negative bus contactor, measuring the voltages using the impedance devices, and comparing the voltages that are measured.
