Abstract: A battery pack is disclosed and includes battery cells, an outer housing, a support structure, and a planar structure. The outer housing is configured to enclose and immerse the plurality of battery cells in a coolant. The outer housing includes multiple walls including side walls, a top wall and a bottom wall. The support structure supports the battery cells. The support structure includes dividing members separating the battery cells. The planar structure is disposed above or below the battery cells. A gap exists between a planar surface of the planar structure and a planar surface of one of the top wall and the bottom wall of the outer housing for flowing the coolant between the planar structure and the one of the top wall and the bottom wall. The planar structure and at least some of the walls direct the coolant to flow across and between the battery cells.

Abstract: A temperature regulation system for a battery is provided. The temperature regulation system includes an electrochemical cell, which may be in the form of a battery. The electrochemical cell includes a housing having a first side surface that extends from a first end to a second end, and a first temperature control chamber containing a dielectric fluid. The first temperature control chamber is located along the first side surface of the housing or along at least one of the first end or the second end of the housing. The dielectric fluid is in direct contact with the housing at the first side surface or at the first end or the second end.
