Articles in Teslarati and wild speculation by Musk fans? The Autoweek article states the same end-of-2021 Cybertruck expectation, and reports that Musk is saying that it won't have 4680 cells. More importantly, even if Cybertrucks with 4680's are pouring off the line this Christmas, galderdi won't see their battery components as affordable salvage in Queensland for years, if ever.I’ve read many articles that say the CyberTruck will have the 4680 cells and the CyberTruck will be sold end of this year. I think Autoweek is somewhat biased.
Aside from the fantasy of the tabless cell, Tesla batteries are useless for this project. Like all production EVs, Tesla batteries are built in modules which are connected in series, so to get to any fraction of the battery overall voltage the salvage user must use that same fraction of the stock modules. Tesla only builds large-battery models, so for this project's target of roughly 1/3 to 2/3 of the usual 360 VNOM pack, 1/3 to 2/3 of the modules would need to be used, meaning for a very basic 60 kWh model (the base Cybertruck will probably have twice that) it would take 20 to 40 kWh of modules. 20 kWh might fit but would have barely adequate voltage; 40 kWh has no chance of going in the GTZ chassis.
Some modules can be broken down and reconfigured: the rare examples with prismatic cells and bolted connections (BMW i3?) can be unbolted and used easily; the most common design of stacked pouches can be disassembled and restacked but ultrasonically welded tabs must be cut apart and rejoined; the cylindrical cells of a Tesla module not only have ultrasonically welded electrical connections but are glued together in a block that can't be torn apart without destroying the pack and likely the cells.
So, the idea is to look for prismatic cells, or modules which are configured for a very small pack such as a high-capacity plug-in hybrid or a very basic battery-electric EV.
