Sandy Munro shows us what a battery with 4,680 Tesla cells could look like


It’s possible that no one is more excited about Tesla Battery Day than Sandy Munro – aside from the fans honking the Teslas in front of Elon Musk after everything he’s said. Munro had better reasons to be delighted. He was almost the size of Tesla’s new cells, and he saw Tesla promise to do something he had planned for in 2017: mega castings. Munro was so enthusiastic that he even created a battery model with 4680 cells.To do this, he had one of the employees at Munro & Associates buy two inch pegs, cut them to size, paint them silver, and put them in an empty Tesla battery shell. . While this is just to give us an idea of ​​what it will likely look like, it was helpful in visualizing what Musk showed off on Tesla Battery Day.

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.
