Generating less heat than the current 2170 cells, the new 4680 batteries will be glued to a cooling plate, which will remove heat from the top and bottom of the cells. These are the places with the most heat during loading and unloading. This is something Munro has been asking to correct since he first took the Tesla battery apart.
Munro also showed how close the cells would be in this new cell-to-pack arrangement. Instead of having cooling ducts placed between the cells, all they will have will be epoxy. The manufacturing simplification this represents is vast, as well as the cost reduction, according to the engineer.
Munro also presented the first car structure with giant castings. It’s from 2017, and it’s not from Tesla, but rather an idea that Munro & Associates gave to dozens of engineers and companies.
Not a single one of them implemented the idea. On the other hand, Tesla liked it and did something similar, if not more sophisticated. We haven’t seen it live yet, but the project was shown at Tesla Battery Day.
Munro and Bob Galyen said the battery will likely outlast the car itself. Still, there are some implications of its integration into body structure that we would like to explore, particularly in regards to how this affects insurance. Stay with us to find out more soon.
