Abstract: A method for abnormality detection in an energy unit includes passively detecting an abnormality in an energy unit by detecting electromagnetic radiation generated by the abnormality, the energy unit comprising at least one of an electrical energy unit and an electrochemical energy unit. A method for detecting an abnormality in an energy unit includes (a) applying a signal to the energy unit, (b) performing a plurality of measurements, at a respective plurality of different locations within the energy unit, of a response of the energy unit to the signal, and (c) processing the plurality of measurements to identify the abnormality.

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).
