Model 3 Uses 2170 Cell, Confirms Tesla – Puts End To 4416 Speculation
The Tesla Model 3 isn’t using some fancy new 4416 battery cell, as reports suggested.
Last evening, through its 2017 Second Quarter Update Letter, Tesla confirmed that the Model 3 used the 2170 cell that we’d been told would be employed in the car in the past. Tesla stated:
“Model 3 drive units as well as battery packs made with our proprietary 2170 form factor cells are being built on new lines at Gigafactory 1. We are now fine-tuning these manufacturing lines to significantly increase the production rate.”
That rules out the larger format 4416 cell for now, but the automaker could employ the more sizeable cell in future iterations of the Model S or X, as suggested in the past. Though Tesla CEO Elon Musk has denied this by stating:
“No plans to change cell form factor for X and S.”
Tesla commenced production of 2170 cells for the Model 3 more than one month ago and it began production of those same cells for its Powerpack and Powerwall units in early 2017.
Eventually one has to assume that all Tesla products will make use of the same cell format to ease production and increase profit. Perhaps that won’t happen until the changeover to the next cell type, maybe the previously reported 4416 cell?
