Embodiment Construction

[0052] Such as figure 1 As shown, the power storage device 10 according to the first embodiment of the present invention is incorporated in a power unit 12 . The power unit 12 is mounted on an electric vehicle (for example, a hybrid vehicle or an EV) that drives a running motor (not shown) with electricity supplied from the power unit 12 .

[0053] The power unit 12 includes a fixing plate (mounting portion) 14 provided on a vehicle frame (not shown). A plurality of sets of power storage modules 16 constituting the power storage device 10 are mounted on the fixing plate 14 via a mounting plate 18 . Another electricity storage module 16 is stacked on any one of the electricity storage modules 16 via a mounting plate 18 a attached to the fixing plate 14 .

[0054] On the fixed plate 14, the control part 20 located in the space part of an approximate center part is mounted. The control unit 20 includes, for example, various devices such as an inverter device, a relay device, a...

Abstract

The present invention provides an electric storage device capable of absorbing the dimensional change easily and reliably even if the size in the stacking direction changes due to the expansion of the electric storage cells, and ensuring a good fixing state between the electric storage module and the mounting plate. . An electrical storage device (10) includes an electrical storage module (16) and a mounting plate (18) connected to the electrical storage module (16). Displacement absorbing parts (46a, 46b) are provided on the mounting plate (18), and the displacement absorbing parts (46a, 46b) extend along the direction of the cell side intersecting with the stacking direction of the electric storage cells (22), and pass through The load in the stacking direction is deformed to absorb the displacement in the stacking direction. The displacement absorbing portions (46a, 46b) are provided on the inside of the screw holes (36a, 36b) in the stacking direction.

Description

technical field [0001] The present invention relates to an electric storage device comprising: an electric storage module in which a plurality of electric storage cells are stacked; the mounting plate. Background technique [0002] Generally, there is known an electricity storage module (battery module) in which a plurality of electricity storage cells (battery cells) are stacked. Since this power storage module is mounted on electric vehicles such as hybrid vehicles and EVs, for example, a high output voltage is set by stacking a plurality of power storage cells. [0003] In the power storage module, a pair of end plates are arranged at both ends of the stacking direction of the power storage cells. The ladder-shaped frame is tightly connected. At this time, since the electric storage module is constituted by laminating a plurality of electric storage cells, there is a problem that the length of the electric storage module is uneven due to the accumulation of tolerances ...
