Battery module construction

摘要

Described are mechanically robust, thermally managed battery module constructions including a battery case, a reinforcing divider in the case, and battery cells housed by the reinforcing divider. The reinforcing divider defines a plurality of thermal transfer elements externalized of the battery case. A shock dampening material can be provided between the reinforcing divider and the battery case to facilitate a mechanical, shock-dampened, reinforcing integration of the divider and case.

1. A battery module, comprising:
a polymeric case defining a plurality of openings in a wall thereof; a shock dampening material received within the polymeric case; a monolithic, thermally-conductive, reinforcing divider partially received within the polymeric case;
the monolithic, thermally-conductive, reinforcing divider structurally reinforcing the polymeric case, with the shock dampening material positioned between the reinforcing divider and the polymeric case and operable to dampen and transfer forces between the polymeric case and the reinforcing divider;the monolithic, thermally-conductive, reinforcing divider including a plurality of dividing wall members defining a plurality of cavities therebetween, with said cavities located within the polymeric case;the monolithic, thermally-conductive reinforcing divider also defining a plurality of thermal transfer projections received through respective ones of the openings of the polymeric case and providing thermal transfer members projecting externally of the polymeric case; a plurality of lithium ion battery pouch cells received within the polymeric case and including lithium ion battery pouch cells received at least partially in respective ones of said cavities of the reinforcing divider; a conductive material electrically coupling at least some of the lithium ion battery pouch cells in series to provide a battery pouch cell series; a negative electrical terminal electrically coupled to a first end of the battery pouch cell series; and a positive electrical terminal electrically coupled to a second end of the battery pouch cell series.
