Battery pack containing phase change material
View Patent ↗A battery pack for a vehicle is presented. The battery pack comprises a plurality of bricks, each brick of the plurality of bricks comprising a phase change material block, a side of the phase change material block defining a plurality of channels, and a plurality of battery cells, each battery cell being disposed at least in part in the phase change material block; and at least one connector for electrically connecting a first one of the plurality of bricks to a second one of the plurality of bricks, the at least one connector being disposed at least partially in one of the plurality of channels.
1. A process for constructing a battery brick for a vehicle, the process comprising:
selecting a plurality of battery cells having a maximum charge temperature and having a maximum discharge temperature greater than the maximum charge temperature;
selecting a phase change material having a melting temperature lower than the maximum charge temperature of the plurality of cells; and
disposing each battery cell of the plurality of battery cells at least in part in the phase change material, the phase change material being selected for dissipating at least a portion of heat generated upon activation of at least a portion of the plurality of battery cells.
2. A process for constructing a battery pack for a vehicle, comprising:
constructing a plurality of battery modules, each battery module comprising a plurality of battery bricks constructed according to the process of claim 1 ; and
connecting the battery modules of the plurality of battery modules to one another.
3. The process of claim 2 , wherein the connecting the battery modules to one another comprises connecting the battery modules to one another in series.
4. The process of claim 2 , further comprising connecting the plurality of battery bricks to one another in series.
5. The process of claim 2 , further comprising connecting the plurality of battery bricks to one another in parallel.
