特斯拉在 Cybercab 机器人出租车的电池包中预留了空间，以便日后改用更便宜的磷酸铁锂（LFP）电芯。据《InsideEVs》报道，特斯拉电池工程师罗伯特·桑普夫在 YouTube 频道 Munro Live 上透露了这一信息。该电池包在模组旁边和下方都留有余地。罗伯特·桑普夫负责特斯拉电池模组和电池包的机械设计。
Tesla designed the Cybercab’s 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’s 4680 cells. Tesla also said the Cybercab line can build cars faster than it deploys them. 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 channel Munro Live, InsideEVs reported. The pack has spare room next to and under its modules.
他说：“因此，随着我们扩大规模并需要将 LFP 引入该平台，我们保护了这个电池包，使其能够过渡到能量密度更低的化学体系。”
Robert Sumpf leads mechanical design for Tesla’s battery modules and packs. “So, we protected this pack to go to an even lower energy dense chemistry as we scale and need to bring LFP into the platform,” he said.
目前，Cybercab 使用特斯拉自产的 4680 电芯，采用镍基化学体系。LFP 电芯储能较少，若电芯数量不变会缩短续航，但特斯拉可以在预留空间里塞入更多电芯。
For now, the Cybercab uses Tesla’s 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.
LFP 电芯成本更低、更稳定、循环寿命更长，这对特斯拉宣称可行驶 50 万英里（约 80 万公里）的车型至关重要。去年，LFP 成为全球使用最广泛的电动汽车电池化学体系。
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’s most used EV battery chemistry last year.
特斯拉副总裁拉尔斯·莫拉维表示，预留额外空间也是因为“我们不需要像原先认为的那么多电池”。每个模组都是独立密封的，出现故障可单独更换，这与 Model Y 的胶粘式电池包不同。
Tesla vice president Lars Moravy said the extra room was also there because “we didn’t need as many batteries as we thought we did.”Each module is sealed on its own, so one that fails can be swapped, unlike in the Model Y’s glued pack.
莫拉维还表示，Cybercab 生产线造车速度快于特斯拉将其投入运营的速度。
Moravy also said the Cybercab factory line can build cars faster than Tesla can put them on the road.
他说：“我们并非每天都开工，因为生产线跑得太快，目前已超过我们的部署节奏，”特斯拉北方网（Tesla North）报道称。
“We don’t run every day because the line can run so fast, it’s currently outpacing our deployments,” he said, Tesla North reported.
目前生产的每一辆 Cybercab 都纳入特斯拉自有车队，特斯拉上周表示 Cybercab 乘车服务将于 11 月在达拉斯启动。8 月，内华达州仅批准了特斯拉在拉斯维加斯申请的 5000 辆机器人出租车中的 10 辆。
Every Cybercab built so far goes into Tesla’s 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.
Cybercab 没有方向盘或踏板。9 月，美国监管机构启动调查，审查特斯拉是如何为该车型进行认证的。
The Cybercab has no steering wheel or pedals. In September, US regulators opened an investigation into how Tesla certified the car.
