BATTERY MODULE

摘要

A battery module includes battery cells, a cover, a conductor, first and second end plates, an elastic body, and a fixing plate. The first and second end plates hold the battery cells from the opposite ends in the aligning direction. The elastic body is arranged between the second end plate and the battery cell that is adjacent to the second end plate. The fixing plate is arranged between the elastic body and the battery cell that is adjacent to the elastic body. The elastic body is configured to be elastically deformed to absorb a load applied to the first and second end plates as the battery cells expand. The fixing plate is fixed to the cover and configured to move with the cover in the aligning direction of the battery cell as the battery cells expand.

主权项

1. A battery module comprising:
a plurality of aligned battery cells, wherein each battery cell has a terminal and a surface on which the terminal is provided; a cover, which faces the surfaces of the battery cells on which the terminals are provided; a conductor, which is connected to the battery cells and fixed to the cover; a first end plate and a second end plate, which hold the battery cells from opposite ends in an aligning direction of the battery cells; an elastic body, which is arranged between the second end plate and the battery cell that is adjacent to the second end plate; and a fixing plate, which is arranged between the elastic body and the battery cell that is adjacent to the elastic body, wherein the elastic body is configured to be elastically deformed to absorb a load that is applied to the first and second end plates as the battery cells expand, and the fixing plate is fixed to the cover and is configured to move in the aligning direction of the battery cells together with the cover as the battery cells expand.
