Problems solved by technology

In this way, when the bus bar plate 805 to which the bus bar 807 is fixed becomes loose, stress concentration occurs at the connecting portion between the bus bar 807 and the terminals 8011 and 8012 of the battery pack 801, thereby causing the connection between the bus bar 807 and the terminals 8011 and 8012 to become loose. The connection part may be damaged

Embodiment Construction

[0051] The power storage device of this embodiment includes:

[0052] a plurality of storage elements arranged in a first direction;

[0053] an adjacent member sandwiched between adjacent two of the plurality of electricity storage elements;

[0054] a holding member holding the plurality of power storage elements and the adjacent member;

[0055] an insulating member interposed between the plurality of power storage elements and the holding member;

[0056] bus bars electrically connecting the external terminals of the storage elements;

[0057] holding the bus bar, and a bus bar holding member arranged along the plurality of power storage elements;

[0058] The bus bar holding member has an elastic deformation portion,

[0059] The elastic deformation portion contacts one of the adjacent member and the insulating member, and presses the bus bar holding member toward the other of the adjacent member and the insulating member.

[0060] According to this configuration, ev...

Abstract

One embodiment of the present invention is characterized by comprising: a plurality of electricity storage elements which are aligned in a first direction; an adjacent member which is sandwiched between electricity storage elements; a holding member which holds the electricity storage elements and the adjacent member; an insulating member which is sandwiched between the electricity storage elements and the holding member; a bus bar; and a bus bar holding member which holds the bus bar, while being arranged along the plurality of electricity storage elements. This embodiment of the present invention is also characterized in that: the bus bar holding member has an elastic deformation part; and the elastic deformation part comes into contact with one of the adjacent member and the insulatingmember, thereby pressing the bus bar holding member against the other one of the adjacent member and the insulating member.

Description

[0001] Cross-references to related applications [0002] This application claims the priority of Japanese Patent Application No. 2018-119023, and the contents of Japanese Patent Application No. 2018-119023 are described in the specification of this application by reference. technical field [0003] The present invention relates to a power storage device including a bus bar holding member for holding a bus bar. Background technique [0004] Conventionally, there is known a battery module in which bus bar plates are assembled on the upper surfaces of a plurality of battery packs (see Patent Document 1). [0005] in particular, Figure 22 As shown, in this battery module, a plurality of battery packs 801 are stacked with a first holder 802 made of synthetic resin having an H-shaped cross-section in between, and two battery packs 801 located at both ends of the stacking direction are stacked outside in the stacking direction. The two second holders 803 made of synthetic resin h...
