[0002] In energy storage battery modules, the end plate is an important structural component, used to fix the battery cells, provide structural support, and provide an interface for electrical connection. Traditional energy storage modules typically require a separate injection-molded terminal (usually a plastic part) to be installed on the end plate. This injection-molded terminal has a metal nut pre-embedded inside to provide the threaded base for bolt connection.

[0003] However, individual injection-molded terminals require separate mold manufacturing, which increases costs. Furthermore, the assembly process after separate production adds an assembly step and reduces production efficiency. Therefore, this phenomenon has become a problem that urgently needs to be solved by those in the field. Utility Model Content
