Abstract
Battery packs are presented. The battery packs include a plurality of cell blocks, each cell block comprising a plurality of battery cells. The battery pack also includes a plenum chamber configured to fluidly couple each of the cell blocks to an exterior of the battery pack in response to a thermal event in the battery cell in a separate cell block. In some embodiments, at least one of the cell blocks is configured to be fluidly coupled to the plenum structure via a cell block vent.
Claims26
A battery pack comprising:
- a plurality of cell blocks each containing at least two battery cells;
- a lateral member coupled to the plurality of cell blocks;
- and
- a plate coupled with the lateral member;
- wherein each cell block comprises a vent facing the plate;
- wherein the plurality of cell blocks, the lateral member, and the plate at least partially define a volume inside the battery pack;
- and
- wherein the volume fluidly couples a cell block to an exterior of the battery pack when the vent of the cell block opens.
A battery pack comprising:
- a plurality of cell blocks each having a battery cell;
- a lateral member positioned amongst the plurality of cell blocks to define a first row of battery cell blocks including a first subset of the plurality of cell blocks and a second row of battery cell blocks including a second subset of the plurality of cell blocks;
- a plate coupled with the lateral member and extending across the first row and the second row, wherein the lateral member, the plate, the first row of battery cell blocks, and the second row of battery cell blocks at least partially define a volume inside the battery pack;
- and
- a battery pack vent coupled with the volume and providing fluid egress from the battery pack.
