How to disassemble the energy storage welding copper plate

How are battery module side plates welded?

Laser cutting and design details for the battery module side plates The side plates of the battery module frame have been cut close to the pressure plates to recover the cells. After replacing battery cells for 2nd life application, the same side plates are welded again with the same pressure plates at a different nearby welding area

Does replacement of failed energy storage modules solve the problem of Battery reliability?

For these reasons, the replacement of failed energy storage modules of a battery pack solves the problem of battery reliability only partially, that is it reduces the number of cells in series, which can fail independently to the number of cells of each module.

What is resistance welding?

Resistance welding has so far mainly been used for joining cylindrical battery cells. It is a fast and easily automated process, but has weaknesses in the case of electrically and thermally highly conductive aluminum and copper materials.

How are 2nd Life busbars welded?

Laser cutting and welding for 2nd life busbars on top of 1st life busbars The cell connecting busbars are cut during disassembly by using laser beam; an isolating tool protects the cells from debris of molten metal and the laser beam. The surface of the busbars is then polished and a new busbar is welded on top
