Was this video already shared? CleanerWatts is explaining that the 4680 "lines" Baglino refers to are not individual production lines. It takes 2 lines (2 different parts of creation / assembly) to create one full production line.
So when they refer to having 4 lines up by 2nd half of the year, they just mean 2 production lines.
Then they will add the other 2 later.
Is this correct?
I think he's off on his conclusions.
Guidance for 4 or 8 lines is meaningless if that is not final cell production lines.
Q3:
The Cybertruck cell with 10% higher energy than our Model Y cell started production on Line 2 in Texas. This quarter, we convert to building 100% Cybertruck cells to simplify and focus the factory as we ramp all four lines in Phase 1 over the next three quarters. Phase 2 of the Texas 4680 facility is currently under construction. The additional four lines incorporate further capital efficiencies over Phase 1, and our target is for them to start producing in late 2024.
If four was really two, then Line 1 and 2 would be all four, and Drew wouldn't say 'ramp all four' after enumerating two lines. Further, if lines come in pairs, it makes no sense to speak of them as seperate items.
Where the confusion may come from:
Q4 call:
And in terms of what we're doing, we're currently running one production line, one assembly line, using two assembly lines in addition for yield and rate improvement trials. And we have a fourth in commissioning, and four more will be installed starting in Q3 this year.
I think he's saying production line means assembly line, not enumerating production line and assembly line as distinct counted items.
My understanding of the current setup per the Q4 call: Line 2 Gen 2 jellyroll production is feeding three Gen 2 assembly lines: Line 2 for production, and Line 1 and 3 for manufacturing trials.
Line 1 jelly roll may be updated, but the production rate doesn't require it.
Overall process:
The electrode creation is typically done in multicell wide rolls. 4680 is no different with slitting done at the end. This is done before transfer to the next stage.
Jelly roll formation takes the electrode rolls, adds the shingles, cuts them to length, rolls and wraps them, and ships them off to assembly.
Assembly takes the jellyrolls, packs them in the cans, places the end caps, laser welds the anode connections, fills them with electrolyte, and seals the fill hole. Then it's off to formation and testing in the racks.
From Q3 call:
Texas had two lines, Line 1 was Gen 1 cells of width X, Line 2 was Gen 2 Cybercells with a taller jellyroll (wider electrode). Both the jellyroll and assembly stages were different due to this. At that time, they were converting Line 1 to the Gen 2 cells.
Q4: Line 1 assembly is converted and being used for trials. Line 3 is a new Gen 2 and being trialed also.
Plan is four assembly lines increasing to eight, and probably an equal number of jellyroll lines.
