Patent number: 8323828Abstract: A battery packet (50) comprises a battery case (51) formed by processing a battery case forming laminated sheet (10), a battery 50a contained in the battery case (51), and tabs (59, 60) extending outside from the battery case (51). The battery case forming laminated sheet (10) is formed by laminating a first base film layer (1a), i.e., an outermost layer, a metal foil layer (2), and a heat-adhesive resin layer (3) in that order. The first base film layer (1a) is a biaxially oriented polyethylene terephthalate resin film or a biaxially oriented nylon resin film. The metal foil layer (2) is an aluminum or copper foil. The heat-adhesive resin layer (3) is formed of a polyolefin resin, more preferably, of an acid-denatured polyolefin resin.Type: GrantFiled: August 12, 2003Date of Patent: December 4, 2012Assignee: Dai Nippon Printing Co., Ltd.Inventors: Takuya Yamazaki, Kiyoshi Oguchi, Koji Shimizu, Kenichiro Suto, Tsutomu Yoshinaka, Hideki Kurokawa, Hitoshi Sekino, Masahiro Yoshikawa, Hiroshi Miyama, Katsuhiko Hayashi, Jun Fukuda

Patent number: 8293393Abstract: An apparatus for simplifying battery pack encapsulation is provided. The battery pack includes a pair of complementary housing members with each housing member including a plurality of cell constraints into which the ends of corresponding battery cells are inserted during assembly. One or both housing members also include at least one, and preferably a plurality, of raised encapsulant injection ports. The raised encapsulant injection ports are designed to extend above the surface of the respective housing members and beyond the injected encapsulation material, thus ensuring that the ports remain open after encapsulation material injection.Type: GrantFiled: March 29, 2012Date of Patent: October 23, 2012Assignee: Tesla Motors, Inc.Inventors: Weston Arthur Hermann, Scott Ira Kohn, Noel Jason Mendez, Ernest Matthew Villanueva, Alexander Thomas Jacobs, Peng Zhou
