What changedTesla says it designed the Cybercab’s battery pack with space for a possible future switch to lithium iron phosphate cells. The company’s battery engineering director says the extra room would let it fit more of the lower-energy-density cells without a straight swap cutting range.
The Cybercab currently uses Tesla’s nickel-chemistry 4680 cells. Tesla has not given a date for an LFP version, named a supplier or explained how a change would affect range, according to Teslarati’s account of a Cybercab deep dive with Munro Live.
The same account says the pack uses four separately sealed modules, so a faulty module could be replaced without scrapping the whole pack. That serviceability could matter for vehicles intended to spend their lives earning fares, rather than gathering dust in a driveway.
Sources and evidence- Tesla’s Cybercab battery design could make robotaxis even cheaper – Teslarati: Tesla reserved space in the Cybercab battery pack for a possible future switch to LFP cells; the pack also uses four separately sealed modules that can be replaced individually, according to Teslarati’s account of a Munro Live deep dive.
