A rechargeable energy storage system (RESS) includes battery cells, each having a respective vent. The RESS also includes a cell support assembly with thermal runaway mitigation, and has a cell holder for supporting the cell. The cell holder defines apertures arranged in rows, and each aperture is in fluid communication with one cell vent. The assembly also includes a plurality of thermal barrier strips adhered to the holder. Each thermal barrier strip extends parallel to a respective row of holes to thermally insulate each corresponding battery cell from gases exhausted by an adjacent battery cell during thermal runaway. The assembly also includes a plurality of potting elements. Each potting element is disposed in one of the apertures between the respective battery cell and the corresponding thermal barrier strip, thereby adhering to the battery cell and the corresponding thermal barrier strip, and maintaining the position of the battery cell on the holder. A motor vehicle may employ such a RESS.
一种可再充电能量存储系统(RESS)包括电池单元,每个电池单元具有相应的通气口。RESS还包括具有热失控缓解的电池单元支撑组件,并且具有用于支撑电池单元的电池单元保持器。电池单元保持器限定成排布置的孔,并且每个孔与一个电池单元通气口流体连通。该组件还包括粘附到该保持器上的多个热屏障条带。每个热屏障条带平行于相应孔排延伸,以使每个对应的电池单元与在热失控期间由相邻的电池单元排出的气体热绝缘。该组件还包括多个灌封元件。每个灌封元件被布置在相应电池单元和对应的热屏障条带之间的孔中的一个孔中,从而粘附到电池单元和对应的热屏障条带,并且维持电池单元在保持器上的位置。机动车辆可以采用这种RESS。
