Description

End plate for square shell battery cell and square shell battery cell Technical Field The utility model relates to the technical field of batteries, in particular to an end plate for a square-shell battery cell and the square-shell battery cell. Background The secondary battery is increasingly used in the fields of electric vehicles and energy storage as an energy storage unit capable of being recycled. When the secondary battery is practically applied, a plurality of single batteries are often required to be connected in series and parallel to form a battery module, and the upper side of the battery is welded with a metal flat cable so as to realize the electric connection among the plurality of batteries, and pole pieces of an anode and a cathode are respectively led out from the battery module. And then, adding end plates made of metal materials at two ends of the battery module and applying pretightening force to clamp the battery pack so as to form the square-shell battery cell. The end plate is embedded with the insert nut, the pole piece corresponds to the insert nut, and the external lead and the pole piece can be mounted on the insert nut through the bolt, so that the conduction of the external lead and the pole piece is realized. In the same size battery cell, in different projects, the position requirements of the insert nuts are different, different end plates are often required to be designed by using scenes, and the cost of the square-shell battery cell is relatively high. Disclosure of utility model The utility model mainly aims to provide an end plate for a square-shell battery cell and the square-shell battery cell, and aims to reduce the cost of the square-shell battery cell. In order to achieve the above object, the end plate for square-case battery cell according to the present utility model includes: The plate body is provided with a first side and a second side which are oppositely arranged, the first side is used for being pressed and held on the battery module, and the second side is sequentially provided with a plurality of first caulking grooves at intervals along a first direction; at least one insert nut for being disposed in a different one of said first caulking grooves, and The plurality of exposing holes are arranged on the upper side wall of the first caulking groove in a one-to-one correspondence mode, and the exposing holes are used for exposing screw holes of the insert nuts.
