Abstract: A modular battery pack and method of making a battery pack. The modular structure includes an open box with an interlocking features to allow for flexibility in assembly of numerous battery pack configurations. The design is such that numerous sub-module assemblies are formed that can be fastened, connected or otherwise secured to a tray, frame or other underlying primary support structure. Aligned stacks of individual battery cells can be placed within the volume defined within the box-like structure so that portions of the box-like structure move in response to a spring-like force imparted by the stack of battery cells. Adapter plates facilitate the modular construction by an interlocking connection between the box-like structure and the underlying support structure.
