Abstract
Battery thermal suppression systems are provided for battery arrays and/or traction battery packs. Exemplary thermal suppression systems may include one or more aerosol devices that are adapted to release potassium (K) radicals when the material temperature reaches a predefined temperature threshold, thereby mitigating the effects of battery thermal events. The aerosol devices may be passive devices that can be implemented at the battery array level, the battery pack level, or both. Each aerosol device may be mounted in relatively close proximity to but without touching the battery cells of the battery array/battery pack.
Claims18
A thermal suppression system for a traction battery pack, comprising:
- a battery array including a plurality of battery cells;
- and
- an aerosol device positioned in a non-contiguous manner with respect to each battery cell of the plurality of battery cells.
A traction battery pack, comprising:
- an enclosure assembly;
- a plurality of battery arrays housed within the enclosure assembly;
- and
- a thermal suppression system including a plurality of aerosol devices mounted to at least one interior surface of the enclosure assembly,
- wherein each of the plurality of aerosol devices includes a polymeric encapsulating material and a potassium aerosol encapsulated within the polymeric encapsulating material.
