The exact numbers are hard to pin down exactly, there are a lot of variables. My current working model is 13 Wh/cell for TE and 20 Wh/cell for TA.Was just typing up something similar, but almost 50% higher numbers.. (guess I used lower energy / cell and added TE cells
Anyway, just to put this in perspective. Assuming your numbers.. and even assuming 24/7 operation (will not happen)..
- 65M cells / month = 2,16M cells / day = 90k cells per hour = 25 cells per second !!
- 195M cells / month = 6,5M cells / day = 271k cells per hour = 75 cells per second !! (run rate end of 2018)
WOW ! Bullet speed indeed !!!
Remember all these cells have to be produced, but also get the initial charge and be aged and tested.
This needs lots of energy and storage space. Just try to imagine.. Flabbergasted I think the word is.
And than doubling that again as targeted in 2020.
I guesstimated 10 GWh for the first phase and 25 GWh for the second phase, but reviewing my numbers I'm not so sure they are entirely accurate.
35 GWh/year and a 50/50 distribution would be 176.8 million cells per month, but there probably should be more TA-cells. 350k Model 3 run rate at ~70 kWh average pack size in late 2018 would be 24.5 GWh/year, 70% of 35 GWh/year. With a 70/30 distribution, 35 GWh/year works out to a little over 160 million cells per month.
If this estimate for late 2018 is correct, I can extrapolate that phase one is around 53 million cells per month. Or 8.27 GWh/year worth of TE cells.
