You generally don’t need to replace the battery of an EV during it’s life time.


Yes, like the almost million mile tesla model S:

As far as we know, the original battery pack had an issue after 290,000 km (180,000 miles) and was replaced under warranty. However, Tesla was initially figuring out the issue and installed a loaner battery, which was used for half a year or 150,000 km (93,000 miles). Then, Tesla installed a new, final battery. We don't have any info about any further replacements, so it might be the first 1 million km battery?

In terms of drive units. The Tesla Model S P85 is a single-motor, rear-wheel-drive car. High power and torque was an issue in the early Teslas, which caused a few motor replacements. Three units were replaced by 680,000 km and the fourth one was running up to 1,000,000 km. We don't have any info on whether anything happened after that.


Yes, because life of battery effectively equals life of vehicle due to eventual depreciation.

For reference, that famous million mile Tesla went through three batteries and eight motors [1].

That depends on how you’re defining lifetime. I doubt the batteries of today will last 12 years, which is the average age of cars on US roads.


What data are you basing this on? From what I've seen Teslas still typically have 80%+ capacity after 200k miles.
