BATTERY MODULE

This application relates to the field of energy storage devices, and in particular, to a battery module. The battery module includes an output electrode base and an end plate, and the output electrode base is inserted into and fitted to the end plate. A first limiting element is disposed on the output electrode base, a limiting plate is disposed on the end plate, and the first limiting element is fitted to the limiting plate to limit relative movement of the output electrode base and the end plate along a first direction. A stop hole is provided in one of the output electrode base and the end plate, and a second limiting element is disposed on the other. The second limiting element is accommodated in the stop hole; and the second limiting element is fitted to the stop hole to limit relative movement of the output electrode base and the end plate along a second direction. According to the battery module provided in this application, the first limiting element is fitted to the limiting plate to limit the relative movement of the output electrode base and the end plate along the first direction, and the second limiting element is fitted to the stop hole to limit the relative movement of the output electrode base and the end plate along the second direction, thereby improving connection reliability of the output electrode base during transport.
