Aspects of the disclosure relate to thermal management aspects of a battery pack. A casted front member of a battery pack enclosure may facilitate cooling of a high voltage distribution box (HVDB) within a cavity of the casted front member. Cooling of other electrical components, such as a busbar can also be provided. Cooling of the HVDB and/or other electrical components external to the battery modules and/or battery cells in a battery pack can facilitate fast charging, vehicle acceleration, component reliability, and/or other advantages.

Thermal control for battery packs

Aspects of the disclosure relate to an enclosure for a battery pack. The enclosure may include one or more casted portions, such as a casted front member and a casted rear member. The casted portions may provide benefits including reducing a number of seal paths on the enclosure, facilitating serviceability of various electrical components from a bottom of the battery pack, reducing a number of parts of the enclosure, facilitating efficient battery pack assembly, facilitating connector placement for ergonomics and/or damage protection, facilitating placement of vents, providing casted in lid, lung, and/or skid plate attachments, and/or improving strike reinforcement features.
