Abstract: The present disclosure is directed to a system and method for calibrating state-of-charge (SOC) of an energy storage device. The method includes monitoring, via a battery management system, at least one of an accumulated capacity of the energy storage device after a first SOC calibration or a time period after the first SOC calibration. Another step includes determining, via the battery management system, whether at least one of the accumulated capacity or the time period is above a predetermined threshold. If at least one of the accumulated capacity or the time period is above a predetermined threshold, then the method includes charging, via the battery management system, the energy storage device for a specified duration until the energy storage device reaches a second SOC calibration.

Abstract: The present disclosure is directed to a system and method for reducing current variability between a plurality of energy storage devices, e.g. battery modules. In one embodiment, the method includes determining a resistance of at least two of the plurality of energy storage devices. Another step includes modifying an operating temperature of one or more of the plurality of energy storage devices when the resistance of one or more of the energy storage devices is outside of a predetermined tolerance range for the energy storage devices. Thus, the step of modifying the operating temperature of one or more of the plurality of energy storage devices causes the plurality of energy storage devices to operate within the predetermined tolerance range.

Abstract: Systems for providing assemblies for containing multi-cell battery systems, and/or multi-cell batteries using such enclosures, are described. A battery case may be partitioned into a battery management portion and a cell portion. Each portion may be configured to accept corresponding battery components in a modular fashion allowing easy installation, removal, and access. The batteries may be configured for convenient handling, storage, and use in a variety of environments.

Abstract: A technique that is usable with a fuel cell includes providing a fuel and oxidant mixture to a reactant chamber of the fuel cell to regulate an electrode potential of the fuel cell during startup or shutdown of the fuel cell.
