Embodiment Construction

[0088] Hereinafter, a battery package according to an embodiment of the present invention will be described with reference to the drawings.

[0089] The above-mentioned battery package is mounted on an electric vehicle, that is, an electric vehicle (EV), such as Figure 1 to Figure 3 As shown, a plurality of battery modules 2, ... and a packaging case 3 for accommodating the battery modules 2, ... are provided. It should be noted that, in each figure, the battery modules 2 , . . . are simply indicated by two-dot chain lines.

[0090] Each battery module 2 is a so-called battery pack in which a plurality of cells are arranged in a row and packaged. In addition, in each battery module 2, a plurality of single cells are electrically connected to each other, and a large-capacity battery is constituted by the plurality of single cells.

[0091] The packaging case 3 includes: a tray portion 30 on which the battery modules 2 , .

[0092] Such as image 3 As shown, the disk portio...

Abstract

Provided is a battery pack that ensures sufficient sealing performance between a tray and a cover by arranging a necessary sealing member between a lower flange portion of the tray and an upper flange portion of the cover that are held in abutment with each other. The tray and the cover covering the tray constitute a packaging case of electric cells. At least a part of a facing surface of at least one of the lower flange portion of the tray and the upper flange portion of the cover that abut each other forms a non-abutting portion that is located apart from the facing surface of the opposite flange portion, and a sealing member is arranged on the non-abutting portion.

Description

technical field [0001] The present invention relates to a battery package mounted on a hybrid electric vehicle (HEV) or an electric vehicle (EV). Furthermore, the present invention relates to an electric vehicle including the battery pack. Background technique [0002] In recent years, from the viewpoint of environmental protection, CO 2 Hybrid electric vehicles with low emissions or no CO emissions 2 Electric motor vehicles (hereinafter, they are collectively referred to as electric vehicles) continue to be popularized. The electric vehicle-mounted battery package is used as a drive motor or an energy supply source for supplying energy to other electric systems. [0003] The battery package includes a plurality of battery modules and a packaging case for accommodating the plurality of battery modules. [0004] Each battery module is a module in which a plurality of single cells are packaged in an electrically connected state. That is, each battery module is a battery p...
