Each line is apparently good for c.10GWh/yr at full capacity (before energy density improvements)
10 GWh/yr was the planned capacity for the Fremont Kato Rd. pilot battery line. The lines going into Austin are nominal 25GWh/yr, although I think that is after a 20% improvement in energy density due to chemistry changes.
The 4 bty lines either installed or under progress now at Austin will be joined by 4 more lines, which Drew Baglino told us on the Q3'22 Conf call will be new tech / lower CapEx for the same capacity (these are likely of type as the further 4/5 lines also planned to go in at Sparks, NV in a year).
Overall, that's 8*25=200GWh planned for Texas
and at least 4*25=100GWh annual capacity planned over the next ~year. I won't be surprised to hear that Berlin is 2nd next, with 8 lines planned (
Model Zwei is coming...) but I don't think Tesla will ever need to build its own battery cells in China (Li
they got).
Cheers!
P.S. Battery cell Line1 at Austin likely supports production of about 166K CTs per year (depending on the cell yield of the battery line, using 1344 cells per car). So 2 Lines together support ~333K CTs, which is near the max capacity of the 1st Cybertruck GA line, now installed and ramping. Another 2 4680 lines by mid-year could support ~500K Models Y, each with a 82 KWh pack (896 cells).
P.P.S. What are the other 4 lines for? More Models Y? Perhaps. But how many Models 2 could be built using those 4680 cells? Assuming a 41 KWh pack (448 cells), that'd be 166K*3*4 = enough cells for 2 Million Models 2 per year. (that's $15B in IRA subsidies to consumers, folks. Congress gonna. be surprised.)
P.3.S. Anybody elsa wanna estimate the annual IRA manufacturer's credits earned for building 2 million 41 KWh packs with both the pack and cells made in USA?
