Problems solved by technology

[0007] However, in the technology described in Patent Document 1, in order to maintain the positional relationship between the battery cells, there is a structure in which both end surfaces of the battery modules are connected by a plate-shaped member extending along the stacking direction of the battery cells. Measures against swelling of each battery cell due to temperature rise or aging change are not disclosed
In addition, if a structure that prevents the expansion of the battery module is applied, problems such as an increase in the size of the battery cell or an increase in the number of parts will easily arise.

Abstract

A battery unit that prevents an expansion of a battery cell, and that can prevent an increase in size of the battery unit or an increase in the number of components. The battery unit includes a box-like battery case that accommodates therein a battery module having a generally rectangular solid shape and including plural sheet-like battery cells stacked flat in a vertical direction of a vehicle body. The battery unit includes: a bottomed box-like casing body that forms a part of the battery case and into which the battery module is accommodated from above the vehicle body; and a fixing plate that abuts on a top surface of the battery module. The battery module is fixed to the casing body with pressure being applied to the battery module from above the vehicle body, by fastening the fixing plate to the casing body. A plurality of battery module is configured.

Description

technical field [0001] The present invention relates to a battery unit, and more particularly to a battery unit suitable for use in an electric vehicle traveling by driving a motor with electric power from a battery. Background technique [0002] Conventionally, as a battery for supplying electric power to a motor of an electric vehicle, a battery using a battery pack in which a plurality of battery cells is assembled, that is, a so-called battery module, is known. [0003] Patent Document 1 discloses a battery unit in which the size in the vertical direction is smaller than the size in the front-rear direction and the vehicle width direction by stacking plate-shaped battery cells having a predetermined thickness along the front-rear direction of the vehicle body. The roughly rectangular parallelepiped battery module. In this battery unit, in order to cool the battery module, cooling air is passed through the gaps between the battery cells in the vehicle width direction of ...
