Thanks very much for the effort. Unfortunately, I think the author is quite messed up. Sigh. There was probably real information that was given to this author. But no way 50 GWh is required for 10k/week Model 3's. Pretty sloppy reporting.
Again, thanks for your effort.
With GF1 at 20 GWh for current vehicle production and Energy hurting for cells, 50 GWh needed when Model 3 reaches 10k/wk does not seem unreasonable, but let's do the numbers:
100 k S/X @87.5 average = 8.75 GWh
500 k 3 @ 70 (80.5 and ~55 with more LR than SR) = 35 GWh
TE @ 1 GWh = 1 GWh
Total: 44.75 GWh
Not including Roadster and Semi
From Electrek:
At 35 GWh, they would be producing at the originally announced production rate, but Tesla has since increased the planned total capacity to 105 GWh of battery cells and 150 GWh of total battery pack output.
