New study proves longevity of electric vehicle batteries
New analysis has found that electric vehicle batteries retain more than 90% of their capacity for more than six years.
The study, carried out by Arval, found that electric vehicle batteries retain 93% of capacity on average after 43,000 miles and more than 90% of capacity on average after nearly 100,000 miles.
Meanwhile, the data also found that battery depreciation is consistent, declining by about one per cent after every 15,000 miles
The data also shows degradation occurs slowly and predictably, with battery performance declining by around 1% every 25,000km following a small initial drop.
Results were based on 24,000 State of Health certificates carried out in 11 European countries. Of these, 66% of the models were pure electric vehicles and 33% were hybrids.
Battery condition
Pascal Seeger, global remarketing director at Arval, said: “This update fully confirms the insights shared last year: batteries maintain a high level of performance over time, beyond market perceptions.
“This is very good news for used car buyers, who can be confident in the durability and reliability of electric vehicle batteries over the long run. By providing consolidated and comparable data, we help remove barriers to buying used electric vehicles and accelerate the development of a more transparent and reliable market.”
Gary Burns, director of procurement and remarketing at Arval UK, added:
“As electric vehicles move into the used market in greater volumes, transparency around battery condition is increasingly important. Encouragingly, the results we’re seeing show that batteries in used EVs stand up well in real-world use, helping to reassure buyers considering this fuel type.”
