A battery assembly includes a casing with a casing wall having inner and outer surfaces and an opening therethrough and being shaped such that a coolant chamber is formed within the casing adjacent to the opening. A sleeve including a compressible material is inserted through the opening. The sleeve is shaped such that a sealing portion thereof is positioned over the outer surface of the casing wall. A battery cell is inserted into the sleeve such that at least a portion of the battery cell is positioned within the coolant chamber. A sealing member is coupled to the casing such that a force is applied onto the sealing portion of the sleeve causing the sealing portion of the sleeve to at least partially compress and seal the coolant chamber.

Battery assembly with immersed cell temperature regulating

Battery assemblies have been provided. In an embodiment, by way of example only, a battery assembly includes a casing including a plurality of walls defining a coolant chamber and a battery cell pocket disposed in the coolant chamber including a container section, a lip, and a first spacer, the lip surrounding the container section and including a casing adjoining section and a pocket adjoining section, the casing adjoining section configured to couple to the casing, and the pocket adjoining section configured to couple to an adjacent lip of an adjacent battery cell pocket, and the first spacer protruding outwardly from the container section.
