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 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.
