New Study: How Long Do Electric Car Batteries Last?

electric vehicle battery

Battery life is a big question as people shop for a used Tesla or other electric car brand. A battery is a lithium ion black box that can make up 50-70% of an electric car’s value. The reality is that if the battery dies, so does the car.

Study takeaways by Recurrent’s team of battery scientists:

  • Battery replacements are quite rare. In our community of 15,000 cars, only 1.5% have been replaced (outside of big recalls like Chevy Bolt).
  • Degradation is not linear. We’re including battery degradation curves that illustrate how well these batteries hold up over time. There’s some drop in the beginning then it levels out for a long period.
  • Most replacements occur under warranty. For example, a new Rivian has battery coverage for 175,000 miles or 10 years. The federal minimum warranty is 8 years or 100,000 miles.
  • This is why Recurrent Reports are essential. Recurrent can give you insights into an EV battery without costly or invasive tests.

If we consider that time is our most valuable thing in life, sitting around for a battery to charge is a huge drain on our time.  I believe are coming up with alternatives that shorten or eliminate this wait and even remove the question of battery life.  Either conductive charging, which could become the grid, battery swaps or exceptional battery range will happen very rapidly and the importance of battery charging machines will lessen.   The French have made charging an exercise in frustration as there are so many companies providing stations now and each has a unique way of operating.

German Company Makes Concrete to Charge Electric Vehicles From Roads With 95% Efficiency and Low Cost

Indiana could be the first state in the Union to have a wireless charging road that tops up your electric vehicle as you drive along it.


This startup can give EVs a full charge in 10 minutes

On a sunny Thursday morning in San Francisco, a driver pulled a Nissan Leaf into a building, parked on a platform, and stepped out of the car. Then the platform lifted the car in the air. Robotic arms carefully pulled out the electric car’s batteries and placed fresh, fully charged batteries inside. The whole process took around 10 minutes.

“Our Next Energy” To Showcase Anode-Free Battery With 600-Mile Range

Earlier this year, Our Next Energy fitted a Gemini battery pack to a Tesla Model S, then drove it for 752 miles in the middle of winter in Michigan.
