Abstract: Computer-implemented technology for identifying or determining potentially damaged batteries in an electrical machine system, and for discharging the potentially damaged batteries. Embodiments include determining potentially damaged batteries by monitoring and determining information representative of one or more electrical or mechanical or thermal conditions of the batteries. The conditions may include isolation faults internal to the batteries, isolation faults external to the batteries, liquid or other contamination of the batteries, and other parameters such as out-of-specification temperatures, pressures, voltages and current levels of the batteries. Embodiments include determining whether to discharge potentially damaged batteries based on one or more of the electrical or mechanical or thermal conditions of the damaged batteries. For example, the computer-implemented technology may determine to not discharge a potentially damaged battery if parameters of the battery indicate that possible hazards or risks may be present based on certain parameters of the battery.
