Abstract
A method for constructing a cell support assembly with thermal runaway mitigation for a multi-cell rechargeable energy storage system (RESS) include forming a cell holder configured to support the RESS battery cells. The cell holder has a holder body defining a plurality of apertures arranged in rows, such that each aperture is configured to align and be in fluid communication with a cell vent of one of the RESS battery cells. Individual embodiments of the method also include various techniques of arranging a plurality of thermal-barrier strips and potting elements to align with apertures of the cell holder body and adhering the thermal-barrier strips to the potting elements and to the cell holder. The resultant cell support assembly operates to channel thermal runaway energy away from the affected battery cell(s) and out of the RESS enclosure without triggering thermal runaway in adjacent cells.
