Copper surface corrosion is an important subject when considering copper busbar joints. When copper is exposed to air and moisture, it forms a thin layer of reddish-brown copper oxide and other corrosion products. These products are not as conductive as the copper, leading to increased resistance at the joint. The increased resistance leads to local heating … Read more
A commonly used material for the pouch cell structure is aluminium laminated film. This pouch material typically consists of a layer of aluminium (Al), coated on the outside with a layer of nylon and/or polyethylene terephthalate (PET) and on the inside with a layer of polypropylene (PP). There are not many configurations of this material out there, most … Read more
The Electric Vehicles Clinic just released details of the Tesla Model 3 cell busbar failures. This is such an important topic that we thought we should cover these findings for the battery design community. In the Tesla Model 3 with the 21700 cell based battery packs the cell connections are single side and the connections … Read more
