Problems solved by technology

[0004] However, in Patent Document 1, since the battery pack is given a constraining load (pressurization force) by pressing the battery pack into the storage portion of a storage case such as a module case as described above, if the battery pack is damaged due to manufacturing errors, If there is a deviation in the size, there is a possibility of deviation in the pressurization force

Embodiment Construction

[0052] The battery module 10 according to the embodiment of the present disclosure will be described with reference to the drawings. In addition, arrow UP, arrow L, and arrow W shown appropriately in each figure indicate the upward direction, the longitudinal direction, and the width direction of the battery module 10 according to the present embodiment, respectively.

[0053]

[0054] First, the structure of the battery module 10 according to the embodiment of the present disclosure will be described.

[0055] figure 1 A perspective view of the battery pack 12 constituting a part of the battery module 10 viewed from an obliquely upper side is shown in .

[0056] like figure 1 As shown, the battery pack 12 is configured to include a battery stack 18 in which a plurality of single cells 16 are stacked in the horizontal direction. In addition, in the battery pack 12 , end plates 20 made of resin are respectively provided at both ends of the battery stack 18 along the stacki...

Abstract

The present invention relates to a battery module and a method for manufacturing the battery module, the battery module comprising: a box-shaped housing case, the upper side of which is opened; a battery pack in which a plurality of unit cells are stacked in the horizontal direction and which is housed in the housing case; and a plurality of types of interstitial pieces made of different materials and disposed between the battery pack and the housing case in a state in which the battery pack is pressurized in the stacking direction of the single cells.

Description

technical field [0001] The present disclosure relates to a battery module and a method of manufacturing the battery module. Background technique [0002] Japanese Unexamined Patent Application Publication No. 2018-032519 (Patent Document 1) discloses a technology in which a battery module is provided with: a box-shaped module case with an upper portion opened; and a battery pack housed in the module. In the housing, the battery pack-side opposing surface and the housing-side opposing surface that face each other between the battery pack and the module housing are each inclined at approximately the same angle. [0003] Therefore, in Patent Document 1, the restraint load can be applied to the battery pack by pressing the battery pack into the housing portion of the module case. [0004] However, in Patent Document 1, since the battery pack is given a constraining load (pressurization force) by pressing the battery pack into the storage portion of a storage case such as a modu...
