Abstract
A battery pack is provided that includes one or more thermal barrier elements, the thermal barrier elements dividing the cells within the battery pack into groups of cells. The thermal barrier elements that separate the cells into groups prevent a thermal runaway event initiated in one group of cells from propagating to the cells within a neighboring group of cells.
Claims23
A battery pack, comprising:
- a battery pack enclosure;
- a plurality of cells contained within said battery pack enclosure;
- and
- at least one thermal barrier element dividing the battery pack into a plurality of cell groups, wherein each of said plurality of cell groups includes at least two cells, wherein each of said at least one thermal barrier elements is comprised of a material with a melting temperature of at least 300° C., and wherein each of said at least one thermal barrier elements prevents a thermal runaway event in a first cell group of said plurality of cell groups from initiating a second thermal runaway event in an adjacent cell group of said plurality of cell groups.
