Battery module, battery pack, electric equipment and manufacturing method of battery module

Abstract

The invention provides a battery module, a battery pack, electric equipment and a manufacturing method of the battery module. The battery module comprises a battery cell assembly, wherein the battery cell assembly comprises a plurality of battery cells; the battery cell comprises an electrode terminal. The first member includes a bottom wall, a side wall, a protrusion, a first space, a first opening, and a second opening. The bottom wall and the side wall form a recess. A portion of each electrode terminal is located in the recess. The convex part is connected to the surface of the bottom wall back to the battery core assembly; in the first direction, the first opening penetrates through the bottom wall. In the second direction, the second opening penetrates through the side wall and the convex part. The first space, the first opening and the second opening are communicated. The first conductive member passes through the first space and the first opening. The first conductive member is connected to the cell assembly. The first glue blocking piece is located on the side, facing the second opening, of the first conductive piece. At least part of the first potting resin is disposed in the first space. The first glue blocking piece is configured to limit the first potting resin from flowing to the concave part. At least a portion of the second potting resin is disposed in the recess.
