The two are connected to form a fully enclosed potting structure, which can effectively control the overflow of potting. The technical solution of step difference design is adopted, and the upper-module nickel sheet positioning surface 1-2 and the lower-module nickel sheet positioning surface 2-2 are designed with inlay according to the nickel sheet thickness. After the nickel sheet is spot welded, it is flush with the outer side surfaces of the upper module 1 and the lower module 2, forming an effective space seal.
[0025] The connection rib 1-4 of the upper module 1 and the connection groove 2-4 of the lower module 2 are connected with each other to form a battery pack structure. The structure of mutual nesting of the rib and the groove is adopted for connection, which can prevent the overflow of potting in the battery pack.
