Abstract: A battery pack includes a first header having a first conduit and a second header having a second conduit. The battery pack also includes an energy storage system having energy storage cells arranged between the first header and the second header. A coolant plate assembly is arranged between the first header and the second header and abuts the plurality of energy storage cells. The coolant plate assembly includes a coolant channel having a first end fluidically connected to the first conduit, a second end fluidically connected to the second conduit, and an intermediate portion defining a flow path. The coolant plate assembly also includes a first planar section having a first surface facing the energy storage cells and a second surface having protrusions extending into the coolant channel.

Abstract: The present disclosure describes a multi-function, integrated Super Beam assembly structure with integrated structural, cooling, and transverse elastic compliance functions; and Thermal Management Propagation (TMP) protection. The Super Beam assembly includes a pair of parallel face plates, coolant channel cover plates, and coolant channels that are defined by the face plate and the one or more coolant channel cover plates. The structural design of the cooling channels, and the corresponding air gaps formed in-between them, allows a transverse elastic compliance of the Super Beam assembly to be tuned to different amounts of elasticity. Top, bottom and/or end structural channels may be included. A pair of TMP suppression channels may be attached to the Super Beam assembly structure with an adhesive “thermal fuse” that preferentially melts and causes the pair of TMP suppression channels to detach from the Super Beam assembly during overheating in a TMP event.

Abstract: Presented are battery assemblies containing long prismatic cells with interleaved gas manifolds and electrical busbars, methods for making/using such battery assemblies, and vehicles equipped with such battery assemblies. A prismatic battery assembly includes multiple stacks of prismatic battery cells that are located inside of and extend longitudinally across a rigid and insulated assembly housing. Each battery cell includes a prism-shaped cell can that contains one or more electrochemical cells. Located at one or both lateral ends of each cell can are a cell vent and a pair of electrical terminals. Electrically connected to the battery cell terminals is an electrical busbar that is located inside the assembly housing, either between the cell stacks or laterally outboard of the cell stacks. Fluidly connected to the battery cell vents is a gas manifold that is located inside the assembly housing, either between the cell stacks or laterally outboard of the cell stacks.

Abstract: A modular multi-cell rechargeable energy storage system (RESS) includes a RESS enclosure surrounded by an external environment and having an enclosure tray and an enclosure cover. The RESS also includes a plurality of battery cell blocks arranged in the RESS enclosure. Each battery cell block includes a cell case including a cell vent and at least one electrically insulated structural connector configured to link the cell case with an adjacent battery cell block. Each battery cell block also includes a thermal mitigation barrier (TMB) segment fixed to the cell case and configured to contact the adjacent battery cell block. Each battery cell block additionally includes a thermal insulator configured to line the cell vent. Furthermore, each battery cell block includes a bus bar segment configured to interconnect with a bus bar segment of the adjacent battery cell block.
