  • Battery module, battery pack, and apparatus using battery cell
    Patent number: 11476533
    Abstract: This application relates to a battery module, including: battery cells arranged sequentially; an end plate that includes a first end sub-plate and a second end sub-plate, where the first end sub-plate and the second end sub-plate are arranged in a length direction of the battery module, the second end sub-plate is closer to the battery cells than the first end sub-plate, and a buffer spacing is formed between the first end sub-plate and the second end sub-plate; and a cell management unit that is disposed on a side of the first end sub-plate facing away from the second end sub-plate. The buffer spacing disposed between the first end sub-plate and the second end sub-plate can effectively reduce or even avoid deformation of the first end sub-plate under an expansion force generated by the battery cells, thereby protecting the cell management unit from a failure caused by the external force.
