Abstract: A battery system may include a plurality of high-voltage (HV) battery packs, each HV battery pack including a plurality of battery cells enclosed within a housing. A battery management system (BMS) can be electrically connected to each of the HV battery packs configured to control the plurality of HV battery packs. The BMS can include a controller configured to identify an isolation breakdown based at least on whether a low resistance connection exists between a portion of a series connection of the plurality of battery cells and a chassis ground of the electric vehicle; and determine an electrical location of a fault in the plurality of HV battery packs based at least on a battery pack positive voltage and a battery pack negative voltage.

Abstract: Vehicle depots or yards adapted to charge multiple electric vehicles include multiple charging electrodes to simultaneously direct power to multiple electric vehicles. The charging electrodes may direct power to the electric vehicles from an utility grid or from a secondary power source.
