Claims18
A coupling structure comprising:
- a first member and a second member which are adjacent to each other,
- wherein the first member and second member are weld-coupled to each other,
- wherein a welding part of the first member and a welding part of the second member comprises:
- a first welding part formed in the first member;
- and
- a second welding part formed in the second member with respect to a coupling surface of the first member and the second member, and
- wherein the first welding part and the second welding part have a mutually asymmetrical shape.
A battery module comprising:
- a cell stack comprising a plurality of battery cells;
- a module frame which houses the plurality of battery cell stacks, the module frame having one side and another other side facing each other that are opened;
- and
- an end plate coupled to the module frame through welding on the one side and the another side of the module frame,
- wherein a welding part of the module frame and the end plate comprises a first welding part formed in the module frame and a second welding part formed in the end plate, with respect to a coupling surface of the module frame and the end plate, and
- wherein the first welding part and the second welding part have a mutually asymmetrical shape.
A method for manufacturing a battery module, the method comprising:
- mounting a battery cell stack comprising a plurality of battery cells on a module frame, of which one side and another side facing each other are opened;
- and
- coupling an end plate to the module frame on one side and the another side of the module frame,
- wherein the coupling of the module frame and the end plate uses a welding method of a Snowman wobble pattern.
