As shown in fig. 1B, on the front surface (end surface perpendicular to the longitudinal direction of the battery assembly 10) 10a side of the battery assembly 10, the bus bar 40 is held by the case 20 in the vicinity of the electrode tab 31 of the battery cell 30. That is, the bus bar 40 is held by the housing 20 by being inserted into an insertion portion (gap) of the bus bar formed on the housing 20.
The electrode tabs 31 of the battery cells 30 and the bus bars 40 are connected by welding at the welding parts 60.
The bus bar 40 and the voltage monitoring line 50 are connected to a terminal portion 51 of the voltage monitoring line 50, but are not fixed to the housing 20. More specifically, as shown in fig. 1B, the bus bar 40 and the voltage monitoring wire 50 are connected to each other at the terminal portion 51 by a rivet 70 as a connection mechanism. The rivet 70 is housed in a recess 21 formed in the case 20 so as to be recessed in the depth direction of the battery module 10 on the front surface 10a side of the battery module 10. In this case, a gap is preferably present between the rivet 70 and the recess 21.
In the present embodiment, a plurality of sets of the bus bars 40 and the voltage monitoring lines 50 are provided corresponding to the plurality of battery cells 30, and at least one of the sets may be connected but not fixed to the case 20. From the viewpoint of more reliably preventing the bus bars from being disconnected due to vibration or the like, and from the viewpoint of making the battery assembly 10 easier to manufacture, it is preferable that 1/3 or more of the plurality of sets, more preferably 1/2 or more of the plurality of sets, further preferably 2/3 or more, and most preferably all of them are connected, but not fixed to the case 20. In particular, in the case where the battery cells 30 are connected in series, it is preferable that all of the plurality of groups are connected to the case 20 but not fixed to the case 20.
Here, "fixed" means a state of being joined to the housing 20 even by mechanical joining, welding, adhesion, or the like, and not being detached from the housing 20 even if a certain force is applied. The "fixed" state does not include the bus bar 40 and the voltage monitoring wire 50 simply making contact with the housing 20 in the movable state.

Negative electrode portion 36 includes a negative electrode sheet (not shown) and a negative electrode active material layer (not shown) provided on a principal surface thereof.
A separator 37 is disposed between the positive electrode portion 35 and the negative electrode portion 36. That is, the positive electrode portion 35, the separator 37, the negative electrode portion 36, the separator 37, and the positive electrode portion 35 \8230, are stacked in this order to form the power storage body 32.
As the positive electrode sheet, aluminum foil or the like can be used. As the positive electrode active material layer, a lithium metalate compound represented by the general formula "LiMxOy (where M is a metal; and x and y are composition ratios of the metal M to oxygen O)" or the like is used. AsThe lithium metal oxide compound includes: lithium cobaltate (LiCoO) 2 ) Lithium nickelate (LiNiO) 2 ) And the like.
As the negative electrode sheet, copper foil or the like can be used. As the negative electrode active material layer, graphite (graphite), silicon oxide, or the like can be used.
The material of the separator 37 is not particularly limited, and examples thereof include: microporous polymer films, nonwoven fabrics, glass fibers, and the like.
The structure of the outer package 33 is not particularly limited. The exterior body 33 has, for example, a first laminated film 38 and a second laminated film 39 formed by laminating a modified PP (polypropylene) layer, an aluminum layer, a nylon layer, and a PET (polyethylene terephthalate) layer from the inner layer side.
The package 33 is formed into a bag shape by welding the edge of the modified PP layer of the first laminated film 38 and the edge of the modified PP layer of the second laminated film 39.
The electrolyte 34 is not particularly limited, and for example, it can be suitably used: electrolytes, electrolytic solutions, and the like used in lithium ion secondary batteries are known. As the electrolytic solution, a mixed solution in which an electrolyte salt is dissolved in an organic solvent can be cited.
The battery unit 30 includes a pair of tabs (terminals), not shown. The battery cell 30 may be charged or discharged through a pair of tabs.
The mass of the one or more battery cells 30 is several tens kg to 100kg, etc., and is relatively heavy.
