Abstract:

A battery module has a lower housing and an upper housing. The lower housing has a plurality of generally vertical sidewalls defining a space for receiving a plurality of battery cells and a generally horizontal bottom wall. The plurality of sidewalls include a first sidewall. The lower housing further has a cooling plate integrally formed with the lower housing. The cooling plate has a support wall extending generally parallel to the bottom wall for supporting the plurality of battery cells, a plurality of generally vertical channel walls including a first channel wall, and a cooling channel for receiving a coolant fluid therein. At least a portion of the cooling channel is defined at sides thereof by the first sidewall and the first channel wall. The upper housing covers a top opening of the lower housing to form an enclosure for the plurality of battery cells.
