Abstract: A battery assembly includes a housing having a base wall, a first end wall, a first side wall, and a second side wall. A plurality of battery cells is arranged in the housing. The plurality of battery cells includes a first plurality of battery cells arranged in a first row and a second plurality of battery cells arranged in a second row. A mid-beam member is arranged between the first row and the second row. The mid-beam member includes a first mid-beam element and a second mid-beam element. The first mid-beam element includes a first end having a first flange. The second mid-beam element includes a first end portion having a second flange. The mid-beam member includes a passage defined between the first mid-beam element and the second mid-beam element.

Abstract: A battery assembly includes a housing having a plurality of side walls that collectively define an interior zone. A plurality of battery cells is arranged in the interior zone. A support assembly connected to the housing supports the plurality of battery cells. The support assembly includes a support plate, an external structural plate, and a channeled cooling plate arranged between the support plate and the external structural plate, and a plurality of channeled cooling plate inflation ports that extend through the support plate towards the channeled cooling plate. The plurality of channeled cooling plate inflation ports introducing an amount of fluid into the support assembly to expand one or more portions of the channeled cooling plate.

Abstract: A battery assembly includes a housing having a battery cell support surface and a plurality of side walls that collectively define an interior zone. A plurality of battery cells is arranged in the interior zone. A heat exchange member is mounted to the housing, the heat exchange member including a bottom plate. A cooling system is arranged in the heat exchange member. The cooling system includes an inflatable bladder arranged between the battery cell support surface and the bottom plate. The inflatable bladder is selectively inflated with a cooling fluid to be brought into contract with the battery cell support surface.

Abstract: A coolant containment system for a battery pack includes a coolant retention container defining a containment space, an inlet connected to the coolant retention container, the inlet connected to an inlet line configured to receive a coolant, an outlet connected to the coolant retention container, the outlet connected to an outlet line, the outlet line configured return a coolant, a drain plug connected to the coolant retention container and in communication with the containment space. The inlet line and the outlet line are disposed entirely within the containment space and any coolant from a leak is retained within the containment space and exits the containment space to an environment outside the battery tray via the drain plug.

Abstract: A modular multi-cell rechargeable energy storage system (RESS) includes a RESS enclosure surrounded by an external environment and having an enclosure tray, an enclosure cover, and a rail structure. The RESS also includes a plurality of mechanically interconnected battery cell blocks arranged in the RESS enclosure. Each battery cell block includes a cell case having at least one interface connector configured to couple the cell case to the rail structure, such that each battery cell block is engaged with and aligned and supported by the rail structure.
