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.

Heat flux assembly for an energy storage device

The present disclosure is directed to an energy storage device having improved thermal performance. More specifically, the energy storage device includes a housing with side walls that define an internal volume. The side walls include bottom and front side walls, with the front side wall having an air inlet and outlet configured to circulate cooling air therethrough. The energy storage device also includes a plurality of cells arranged in a matrix within the internal volume atop the bottom side wall. Further, the cells define a top surface. Further, the energy storage device includes an exhaust manifold adjacent to the front side wall between at least a portion of the cells and the air inlet. Thus, the exhaust manifold is configured to direct airflow from the top surface towards the bottom side wall and then to the air outlet so as to provide an airflow barrier between cooling air entering the air inlet and the cells.

Energy storage device having improved thermal performance

The present disclosure is directed to an improved energy storage device having a housing with one or more side walls that define an internal volume. The side walls include a bottom side wall and a front side wall having an air inlet and outlet. The energy storage device also includes a plurality of cells arranged in a matrix within the internal volume atop the bottom side wall. Further, the cells define a top surface. In addition, the energy storage device includes an airflow distribution network configured with the air inlet and the air outlet. Moreover, the airflow distribution network is at least partially sealed from the plurality of cells (e.g. at the front side wall) so as to reduce temperature variability across the cells when external air is provided through the air inlet.
