Abstract

A support frame assembly for holding a plurality of battery cells includes a first end frame having a first plurality of protruding strips, a second end frame having a second plurality of protruding strips, and a structural frame having a plurality of grooves for receiving the first plurality of protruding strips and the second plurality of protruding strips. The first end frame and the second end frame attach to the structural frame to hold a first battery cell, a second battery cell and a foam pad positioned between the first battery cell and the second battery cell. The structural frame has curved features therein for receiving a cooling assembly and a chamfered slot for receiving a cooling fin from the cooling assembly. The support frame assembly also includes interlocking features that mate to another support frame with a gap defined between adjacent support frames.
