How long do EV batteries last?

Geotab research shows that EV batteries could last 20 years or more if they degrade at an average rate of 1.8% per year, as we have observed. With fleet operators and managers under increasing pressure to reduce CO 2 emissions — from government mandates, investors, environmental groups, the public and other stakeholders, this is great news.

Can EV batteries predict life expectancy?

This is not a good way to predict the life expectancy of EV batteries, especially for people who own EVs for everyday commuting, according to the study published Dec. 9 in Nature Energy. While battery prices have plummeted about 90% over the past 15 years, batteries still account for almost a third of the price of a new EV.

How often do EV batteries degrade?

Our latest research finds that EV batteries are degrading at 1.8% per year on average. The last time we analyzed battery degradation in 2019, we found an average annual degradation rate of 2.3% (which was already quite good). See figure 1 below for the battery degradation rates of the 11 EV models analyzed. Is EV battery degradation linear?

Can a real-world stop-and-go battery make a battery last longer?

Consumers’ real-world stop-and-go driving of electric vehicles benefits batteries more than the steady use simulated in almost all laboratory tests of new battery designs, Stanford-SLAC study finds. The way people actually drive and charge their electric vehicles may make batteries last longer than researchers have estimated. | Cube3D

How long does a lithium ion battery last?

The truth is that when treated correctly most modern lithium-ion units are likely to last the lifetime of the car. Even so, most firms cover the battery with a separate, extended warranty. Most car warranties are around three years and 60,000 miles, but this is increased for the battery element in EVs.

Do EV batteries need to be replaced?

This suggests that the owner of a typical EV may not need to replace the expensive battery pack or buy a new car for several additional years. Almost always, battery scientists and engineers have tested the cycle lives of new battery designs in laboratories using a constant rate of discharge followed by recharging.
