Abstract: An energy storage system can include an energy storage device, such as a battery energy storage device, having a first terminal and a second terminal. A first unidirectional contactor can be coupled to the first terminal. A second unidirectional contactor can be coupled to the second terminal. The first unidirectional contactor can be coupled to the energy storage device with opposite polarity relative to the second unidirectional contactor. The first unidirectional contactor and the second unidirectional contactor can be controlled based on direction of current flow associated with the energy storage device.

Abstract: Systems and methods for controlling performance parameters for an energy storage device include providing primary control signals to an energy storage device that indicate at least one operating value in a range defined by at least one set point value for one or more performance parameters of the energy storage device. In one embodiment, an actual performance score for the energy storage device operated in accordance with the primary control signals is determined and compared with a required performance score to determine a performance score evaluation parameter. Additional control signals are then determined and provided to the energy storage device in a manner that adjusts the at least one operating value of the one or more primary control signals relative to the at least one set point value for the one or more performance parameters based at least in part on the performance score evaluation parameter.

Abstract: The present disclosure is directed to a heat flux assembly for an energy storage device. The energy storage device includes a housing with a plurality of side walls that define an internal volume and a plurality of cells configured within the internal volume. The heat flux assembly includes a plurality of heat flux components configured for arrangement with the side walls of the housing of the energy storage device and one or more temperature sensors configured with each of the plurality of heat flux components. Thus, the temperature sensors are configured to monitor one or more temperatures at various locations in the plurality of heat flux components. The heat flux assembly also includes a controller configured to adjust a power level of each of the heat flux components as a function of the monitored temperature so as to reduce a temperature gradient or difference across the plurality of cells during operation of the energy storage device.
