Abstract
Battery thermal suppression systems may be 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 aerosol particles that may be distributed over and/or around battery cells/battery arrays during battery thermal events, thereby mitigating thermal propagation. The aerosol devices may be active or passive devices and can be implanted at the battery array level, the traction battery pack level, or both.
