Abstract: The invention is a battery clamshell plate comprising a plurality of laminate layers stacked and connected together. The laminate layers may be made of printed circuit board (PCB). The laminate layers may have cut outs to house battery cells, of which the battery cells are connected to the battery clamshell plate by friction or mechanical means. The invention considers strategies to minimize weight and to ensure resistance to shock and vibration failures. This invention also considers air cooling in between cells.

Abstract: A clamshell plate for a battery pack is configured to facilitate connection via adhesive to a plurality of battery cells.
