Film covered electrical device, frame member, and housing system for film covered electrical device

#This application claims priority from PCT Application No. PCT/JP2005/006081 filed Mar. 30, 2005, and from Japanese Patent Application No. 2004-107383 filed Mar. 31, 2004, which applications are incorporated herein by reference.

#The present invention relates to a film covered electric device, a frame member, and a housing system for a film covered electric device.

#In recent years, an electric automobile or a hybrid electric automobile (hereinafter, simply called “electric automobile”) mounted with a battery for driving a motor has been rapidly developed. The battery mounted on the electric automobile is required as a matter of course to have reduced weight in order to improve drivability and mileage per charge. In order to reduce battery weight, a film covered battery has been developed using a laminate material formed into a thin film by laminating a metal layer, like aluminum, and a thermal-melt resin layer through an adhesive layer on the covering body. The laminate material generally has a structure, in which both surfaces of the thin metal layer, like aluminum, are covered with thin resin layers, and is resistant to acid and alkali and is lightweight and flexible.

#FIG. 1 is a perspective external view schematically showing a laminated battery of a first embodiment according to the present invention.

#FIG. 2 is a perspective exploded view schematically showing the laminated battery shown in FIG. 1.

#FIG. 3a is a cross-sectional view taken along line A-A in FIG. 1.

#Next, explanations are given of embodiments of the present invention with reference to drawings.

#FIG. 1 is a perspective external view schematically showing a laminated battery of a first embodiment, and FIG. 2 is a perspective exploded view schematically showing the laminated battery according to the first embodiment.

#FIG. 3a is a cross-sectional view taken along line A-A in FIG. 1, and FIG. 3b is a plane perspective view of the laminated battery.
