Here's How Much Range EVs Really Lose After 150,000 Miles

"Battery degradation on high-mileage EVs is not as big a deal as some might make you believe. Real-world data shows that EVs with over 150,000 miles are still going strong, with minimal degradation. Older EVs are more affected by high mileage, but technology has made newer models more resilient. Battery degradation is inevitable, but new research shows that EV owners should just keep driving their cars without worrying about what happens with the thousands of cells that live in their cars' floors."

"The findings clearly show that technology has progressed a lot in the past decade, to the point where a 2023 model has 10% less degradation than a 2012 EV with the same mileage on the clock. Advancements in battery chemistry, thermal management and buffer strategies have made third-generation electric cars extremely dependable. The oldest EVs with 150,000 miles in Recurrent's analysis are from 2012, while the newest were made in 2023."

"The firm looked at the real-world range of about 1,000 EVs in its portfolio that have driven over 150,000 miles since new. Then, Recurrent compared these findings with the real-world range of the vehicles when they were new, instead of the official EPA estimates. The findings clearly show that technology has progressed a lot in the past decade, to the point where a 2023 model has 10% less degradation than a 2012 EV with the same mileage on the clock."

Recurrent analyzed about 1,000 EVs with more than 150,000 miles and compared each vehicle’s current real-world range to its original real-world range rather than EPA estimates. The oldest vehicles in the set date to 2012 and average roughly 81% range retention, while 2023 models retain about 91% of original capacity. Improvements in battery chemistry, thermal management, and buffer strategies have increased resilience. Third-generation electric cars show significantly lower degradation. Battery degradation remains inevitable but is minimal in modern EVs, so owners can expect dependable range even at high mileage.
