Embodiment Construction

[0045] [Schematic Configuration of Battery Module]

[0046] will now refer to figure 1 , figure 2 and image 3 Embodiments of the battery module according to the present disclosure will be described. figure 1 is a diagram showing six views (front view, right side view, left side view, bottom view, plan view, and rear view) of the battery module 100 . figure 2 is a cross-sectional view of the battery module 100 . image 3 is a perspective view of the battery module 100 .

[0047] The battery module 100 includes a battery cell group 103 arranged between end plates 101 and 102 used as a first regulating plate and a second regulating plate. The middle plate 104 is inserted in the middle of the battery cell group 103 . Attachment pieces 105 a and 105 b are formed on the lower portion of the middle plate 104 . The intermediate plate 104 between the end plates 101 and 102 is a plate made of metal such as aluminum or iron.

[0048] The battery cell group 103 is formed by sta...

Abstract

A galvanic module having a plurality of galvanic units arranged so that the principal surface of a galvanic cell and the surface of a heat-transfer plate held by a galvanic support body made from an insulating material face each other, the galvanic module being obtained by stacking the galvanic units. The galvanic units are positioned so that a facing arrangement is adopted for the galvanic support body made from an insulating material for holding the heat-transfer plate, as well as for the surface of the heat-transfer plate and the principal surface of the galvanic cell.

Description

technical field [0001] The present disclosure relates to battery units, battery modules, power storage systems, electronic equipment, power systems, and electric vehicles. Background technique [0002] Lithium-ion batteries using carbon for the negative electrode, lithium transition metal composite oxides for the positive electrode, and carbonate mixtures for the electrolyte have been known for a long time. In lithium-ion batteries with this configuration, since carbonates are stable against oxidation and reduction of water and other organic solvents and higher voltages can be obtained, it is possible to obtain ) Ni-MH batteries have greater energy density and higher capacity. Therefore, lithium ion storage batteries are widely popularized as storage batteries for electric tools, laptop computers, mobile phones, video cameras, digital cameras, and the like. [0003] In recent years, lithium-ion secondary batteries have begun to spread to applications other than the above-m...
