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.

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.
