Currently, in the 2170 battery packs, the cells are cooled from the sides but in the future, Tesla is planning to do it the right way, installing a cooling plate underneath the batteries. Tesla Structural Battery with new formation of the 4680 cells will be as rigid as a brick you could ever imagine, says Sandy Munro.
Tesla Structural Battery with new formation of the 4680 cells will be as rigid as a brick you could ever imagine, says Sandy Munro. With single-piece front and rear castings and the structural battery in the middle, Tesla cars will be virtually twist-proof in an accident.
Nonetheless, cell characterization reveals very good specs already. Tesla's 4680-type battery cell weight was 355 g. The estimated total capacity is 26.136 Ah, while total energy is estimated at 96-99 Wh (assuming at 3.7-3.8 V).
Tesla CEO Elon Musk showed the road to 56% cheaper batteries in the near future. This would be achieved with Tesla’s breakthrough innovations in cell chemistry and materials, simplifying and speeding up the cell manufacturing processes, a structural battery, and the new 4680 form factor.
Tesla's 4680-type battery cell weight was 355 g. The estimated total capacity is 26.136 Ah, while total energy is estimated at 96-99 Wh (assuming at 3.7-3.8 V). That would be in-line with the rumor about 98 Wh capacity.
Sandy Munro measured the length of the steel case cover of the 2170 battery cells and found out that with a lesser number of 4680 cells, Tesla will alone be able to reduce around 30-40% use of steel in the battery pack (see Fig 7 below). Fig 7: Usage of steel reduces by about 30-40% with the new 4680 battery cells (infographic).
