  • Patent number: 10389141
    Abstract: A plurality of battery packs is provided in communication with an energy monitoring and control system. Each battery pack includes a plurality of battery cells that collectively dictate the capabilities of the battery pack. The energy monitoring and control system determines a plurality of pack charging or pack discharging parameters for each battery pack that, when performed, achieve one or more performance metrics at a user level (e.g., performance metrics of each battery pack within a system of multiple battery packs). The battery pack further determines a plurality of cell charging or cell discharging parameters for each battery cell based upon the determined plurality of pack charging or pack discharging parameters for each battery cell that, when performed, achieve one or more performance metrics at a battery level (e.g., performance metrics of different cells of each battery pack).

  • Patent number: 10330732
    Abstract: A system and method for monitoring characteristics of an electric energy device includes generating an external short from the electric energy device. The external short occurs at a known distance from a sensor and has at least one known external resistance. The received signal representing change in electromagnetic field due to the applied external short may be analyzed to determine a signal parameter that is then analyzed in comparison to a lookup table, based on the known conditions including distance, temperature and the external resistance. The output of this analyses in comparison with expected values may be utilized to identify a characteristic of the energy device.
