| description | This application relates to the field of energy storage devices, and in particular, to a battery module, including: a plurality of 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. According to the battery module provided in this application, the buffer spacing disposed between the first end sub-plate and the second end sub-plate can effectively avoid deformation of the first end sub-plate under the effect of an expansion force generated by the battery cells, thereby protecting the cell management unit disposed on the side of the first end sub-plate facing away from the second end sub-plate from a failure caused by the external force. This improves the life of the cell management unit and further improves the service life of the battery module. This application further relates to a battery pack and an apparatus using a battery cell. |
