Battery system having a battery module

A battery module, comprising:

• a first retention housing having a first plurality of cylindrical battery cells therein;
• a battery cell retention frame being disposed in the first retention housing, the battery cell retention frame having a central cooling plate member and a first thermally conductive layer,
• the central cooling plate member having first and second manifold portions and first and second intermediate walls disposed between and coupled to the first and second manifold portions;
• the first and second intermediate walls defining an internal cooling channel therebetween that fluidly communicates with the first and second manifold portions, the first thermally conductive layer being coupled to the first intermediate wall;
• a first retaining plate being disposed in the first retention housing, the first retaining plate having a first plurality of apertures extending therethrough, each aperture of the first plurality of apertures being sized to allow a bottom surface of a respective cylindrical battery cell of the first plurality of cylindrical battery cells to contact the first thermally conductive layer.

A battery module, comprising:

• a first retention housing having an end wall with a first plurality of alignment tabs;
• the first retention housing holding a first plurality of cylindrical battery cells therein such that each alignment tab of the plurality of alignment tabs holds a respective cylindrical battery cell of the first plurality of cylindrical battery cells at a desired respective position;
• a battery cell retention frame being disposed in the first retention housing, the battery cell retention frame having a central cooling plate member with first and second thermally conductive layers;
• the first plurality of cylindrical battery cells thermally communicating with the first thermally conductive layer.
