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.

Energy storage device with reduced temperature variability between cells

A cell module and modular cell tray apparatus for a modular electrochemical device that are more easily manufactured and serviced. A cell module is provided having a plurality of electrochemical cells. The cell module includes an electrically conductive carrier element having a plurality of apertures, wherein each aperture is configured to accept a top portion of an electrode body of an electrochemical cell. A modular cell tray apparatus is provided having a plurality of the cell modules. The cell tray apparatus includes an electrically insulating tray having rows of cell receptacles to accept the cell modules. A modular electrochemical device is provided having a plurality of the cell tray apparatuses. The modular electrochemical device includes a plurality of electrical connectors configured to electrically connect the cell modules within a cell tray apparatus, and to electrically connect the cell tray apparatuses to each other.
