Abstract

An energy storage module 11 comprises a case 21 , a plurality of stacking plates 41 , a heat-transferring metal plate 51 and a heat-releasing fin 61 . An exposure outlet 23 is provided on the side 21 of the case 22 containing a plurality of energy storage cells 31 . The stacking plate 41 having an aperture 42 is located between the plurality of energy storage cells 31 and is latched to another stacking plate 41 to position said plate. The heat-transferring metal plate 51 having a flat plate portion 52 and a bent portion 53 is provided in face-to-face contact with the main face 33 of each cell of the energy storage cells 31 . The heat-releasing fin 61 projects from the exposure outlet 23 to the outside of the case 21 and is thermally face-to-face bonded to the bent portion 53 of the heat-transferring metal plate 51 by the insulation sheet 65.

First claim

What is claimed is:

1. An energy storage module comprising a structure in which a plurality of energy storage cells, as well as power-generating elements in an electrolyte solution, are stored inside a metal-laminated film material, with the plurality of energy storage modules being provided face to face, pressed in a direction of lamination of the metal, thus forming layers to be connected in series or in parallel, characterized in that the energy storage module comprises:
a case forming a box with four sides, with an exposure outlet provided on one or two sides of the case, the case completely surrounding the plurality of the energy storage cells,
a plurality of stacking plates made of plate frame parts with an aperture and a positioning projection provided between the energy storage cells, the positioning projection detachably engaged to an adjacent stacking plate thus positioning each other,
a heat-transferring metal plate having a flat plate portion affixed to the stacking plate covering the aperture and a bent portion to bend at right angle an edge of the flat plate portion located on the exposure outlet provided in face to face contact with each cell of the energy storage cells, and
a heat-releasing fin projecting from the exposure outlet leading to an outside of the case and a heat-transferring insulation sheet thermally face-to-face bonding the bent portion and the heat-releasing fin, wherein only the heat releasing fin is projected from the exposure outlet leading to an outside of the case, characterized in that the case is made of resin, therein a metal fitting is formed by bending a metallic plate, the metal fitting contiguously provided on an outer surface of the case that does not have the exposure outlet, and that the heat-releasing fin is indirectly provided on the case with the metal fitting affixed to the outside of the case.

2. An enemy storage module comprising a structure in which a plurality of energy storage cells, as well as power-generating elements in an electrolye solution, are stored inside a metal-laminated film material, with the plurality of energy storage modules being provided face to face, pressed in a direction of lamination of the metal, thus forming layers to be connected in series or in parallel, characterized in that the energy storage module comprises:
a case forming a box with four sides, with an exposure outlet provided on one or two sides of the case, the case completely surrounding the plurality of the energy storage cells,
a plurality of stacking plates made of plate frame parts with an aperture and a positioning projection provided between the energy storage cells, the positioning projection detachably engaged to an adjacent stacking plate thus positioning each other,
a heat-transferring metal plate having a flat plate portion affixed to the stacking plate covering the aperture and a bent portion to bend at right angle an edge of the flat plate portion located on the exposure outlet provided in face to face contact with each cell of the energy storage cells, and
a heat-releasing fin projecting from the exposure outlet leading to an outside of the case and a heat-transferring insulation sheet thermally face-to-face bonding the bent portion and the heat-releasing fin, wherein only the heat releasing fin is projected from the exposure outlet leading to an outside of the case, characterized in that the bent portion of the heat-transferring metal plate is bent along a side of the stacking plates.
