3000 cycles in an EV with a range of 300 miles is 900,000 miles. That's a lot. Early EV batteries weren't that good; probably closer to 1000 cycles. At best. Which is still 300,000 miles. And of course some of the earlier ones were actually not that good even and had more primitive cooling and battery management systems. Most recent EVs have warranties of eight years or 100,000 miles. Reason: manufacturers know it is extremely unlikely for any issues to emerge with the drive train during this time. Tesla was talking about the million mile battery during battery day a few years ago. A bit over 3000 cycles would get you there. It's a very realistic target. What that means practically is that the drive train survives the car typically.
