429066000 | HAVING MEANS TO ACCOMMODATE ELECTRODE EXPANSION | 13 |
20110262785 | BATTERY MODULE - A battery module that includes a battery unit composed of a plurality of flat cells and having an end face, a container with an end piece that encloses the battery unit, and a damping assembly disposed between the end face and the end piece. The damping assembly includes a pressure plate, coupled to the end face, that distributes a force substantially equally over the end face. The damping assembly further includes a damping mechanism that damps battery unit oscillations within the container and applies the force to the pressure plate. Coupling the end plate to the damping mechanism compresses the damping mechanism, and causes the damping mechanism to exert a reactionary force against the pressure plate. Furthermore, the damping assembly compresses and substantially suspends the battery unit within the container, such that one face of the battery unit does not substantially contact the container interior. | 10-27-2011 |
