Embodiment Construction

[0047] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0048] Such as figure 1 As shown, the battery case 10 is composed of a box-shaped container having a rectangular bottom wall 11 in plan view and a standing wall 12 standing upright from the upper surface of the bottom wall 11 with an upper opening. The battery case 10 is formed in an elongated shape in the X direction in the drawing. In addition, among the directions shown in the figure, the X direction represents the longitudinal direction of the battery case 10 . The Y direction represents the width direction of the battery case 10 . The Z direction represents the height direction of the battery case 10 .

[0049] The standing wall portion 12 has side wall portions 121 , 121 , end wall portions 122 , 122 , intermediate wall portions 123 , 123 , and central end wall portions 124 , 124 . The side wall portions 121 , 121 are arranged at both end portions in...

Abstract

The problem to be solved by the present invention is to provide a method for manufacturing a storage battery case and a storage battery case, which can be cast so that the inner surface of a standingwall portion becomes a vertical surface, and which can improve the cell mounting density. In order to solve the above problem, the present invention provides a method for manufacturing a battery case(10) in which a plurality of cells (100) are housed inside a box-shaped container having a bottom wall section (11) and a standing wall section (12) standing upright from the bottom wall section (11)and having an opening at the top, the method for manufacturing a battery case (10) being characterized in that: when the battery case (10) is cast, a first core (20), the outer surfaces (21a, 22a) ofwhich are perpendicular to the bottom wall section (11) and the inner surfaces (21b, 22b) of which have a mold release slope that is inclined with respect to the bottom wall section (11), is disposedat a position inside the mold (50) corresponding to the inside of the vertical wall section (12) of the battery case (10) for casting.

Description

technical field [0001] The invention relates to a method for manufacturing a battery box and the battery box. Background technique [0002] In electric vehicles and hybrid vehicles, as a power source for driving a motor, a battery pack is equipped with a plurality of battery cells composed of secondary batteries such as lithium-ion batteries (hereinafter referred to simply as "" "Single".) Stored in the battery box. [0003] Conventional battery packs are configured by binding a cell pack formed by stacking a plurality of batteries using restraint parts such as fastening bars to perform modularization, and storing the modularized cell pack in a battery case. However, when a plurality of cells are modularized and accommodated in a battery case, the plurality of cells cannot be efficiently accommodated, and the mounting density of the cells with respect to the battery case is low. Therefore, it is desired to store a plurality of cells directly in the battery box without modu...
