<\/p>\nTesla designed the Cybercab\u2019s battery pack with spare space so it can later use cheaper lithium iron phosphate (LFP) cells, battery engineer Robert Sumpf told Munro Live. The robotaxi now uses Tesla\u2019s 4680 cells. Tesla also said the Cybercab line can build cars faster than it deploys them.<\/p>\n
Tesla designed the battery pack in its Cybercab robotaxi so it can later switch to cheaper lithium iron phosphate (LFP) cells. A Tesla engineer said so on the YouTube<\/a> channel Munro Live, InsideEVs reported<\/a>. The pack has spare room next to and under its modules.<\/p>\n Robert Sumpf leads mechanical design for Tesla\u2019s battery modules and packs.<\/p>\n \u201cSo, we protected this pack to go to an even lower energy dense chemistry as we scale and need to bring LFP into the platform,<\/em>\u201d he said.<\/p>\n For now, the Cybercab uses Tesla\u2019s own 4680 cells with a nickel-based chemistry. LFP cells store less energy, so the same number of cells would cut range, but Tesla could fill the spare space with more of them.<\/p>\n LFP cells are cheaper, more stable and last more charging cycles, which matters for a car Tesla says is built to run 500,000 miles. LFP became the world\u2019s most used EV battery chemistry last year.<\/p>\n Tesla vice president Lars Moravy said the extra room was also there because \u201cwe didn\u2019t need as many batteries as we thought we did.<\/em>\u201d Each module is sealed on its own, so one that fails can be swapp<\/a>ed, unlike in the Model Y\u2019s glued pack.<\/p>\n Moravy also said the Cybercab factory line can build cars faster than Tesla can put them on the road.<\/p>\n \u201cWe don\u2019t run every day because the line can run so fast, it\u2019s currently outpacing our deployments,<\/em>\u201d he said, Tesla North reported<\/a>.<\/p>\n Every Cybercab built so far goes into Tesla\u2019s own fleet, and Tesla said last week that Cybercab rides would start in Dallas in November. In August, Nevada approved just 10 of the 5,000 robotaxis Tesla asked for in Las Vegas.<\/p>\n The Cybercab has no steering wheel or pedals. In September, US regulators opened an investigation into how Tesla certified the car.<\/p>\n<\/p><\/div>\n If you liked the article, do not forget to share it with your friends.
