Embodiment Construction

[0049] Hereinafter, the embodiments will be described with reference to the accompanying drawings. It should be noted that the following embodiments are described by way of example only, and are not intended to exclude various modifications and technical applications not explicitly shown in the following embodiments.

[0050] will refer to Figure 1 to Figure 5 The structure of the battery case according to the present embodiment is described. Such a battery case is suitable for accommodating a battery module (battery) for driving an electric vehicle including a hybrid electric vehicle. Hereinafter, the traveling direction of the electric vehicle is regarded as "front", and "left" and "right" are defined with respect to the front. In addition, the direction of gravity is regarded as "below", whereas the direction opposite to below is regarded as "upper". In addition, the direction toward the center of the battery case is regarded as "inside", and the direction opposite to t...

Abstract

A battery casing (7) for receiving a plurality of battery modules (8) for driving an electric vehicle (1), including: a tray member (10) made from a resin and supporting the battery modules (8); a support member (30) provided under a lower face of the tray member (10) and supporting the tray member (10) from a bottom thereof; a standing wall (11a,11b,13F,13R) provided so as to stand in the tray member (10); and a sheet metal tray member (40) made from a sheet metal and placed on the tray member (10). The sheet metal tray member (40) includes a plurality of sheet metal recesses (41) that receive the battery modules (8) and a sheet metal flange (42) placed on an upper face of the standing wall (11a,11b,13F,13R). The standing wall (11a,11b,13F,13R) includes a through hole (6) formed through the standing wall (11a,11b,13F,13R) in a standing direction of the standing wall. The support member (30) and the sheet metal flange (42) are fastened to the tray member (10) by means of a sheet metal fastening member (50) provided through the through hole (6).

Description

technical field [0001] The invention relates to a battery box for accommodating a battery module for an electric vehicle. Background technique [0002] A battery unit for an electric vehicle generally includes a plurality of battery modules and a battery case that accommodates the battery modules. As disclosed in Japanese Patent Laid-Open No. 2010-153130 (JP 2010-153130A), one type of structure of a battery case includes a tray member supporting the battery module and a cover member covering the top of the tray member. In this structure, the tray member and the cover member are joined together with a plurality of bolts and nuts at the joint between the periphery of the tray member and the periphery of the cover member. [0003] A tray member included in a battery case disclosed in JP 2010-153130 A has a partition wall extending in the width direction for dividing the tray member in the longitudinal direction, and a partition wall extending in the front-rear direction for di...
