Electric Vehicle Batteries Last Longer Despite Fast Charging Wear, Study Finds
Richard Symons, owner of a British used electric vehicle (EV) sales company, recently completed a 400-kilometer trip in his five-year-old Tesla Model 3 without stopping to recharge. His car, affectionately named "Miles," has nearly 400,000 kilometers on its original battery, demonstrating the durability of modern EV batteries. Symons told the Wall Street Journal that batteries remain reliable even after extensive use.
Supporting this, research firm Recurrent, which monitors battery health, reports that an average EV retains up to 95% of its original driving range after five years, surpassing industry expectations. Early EV models, such as the original Nissan Leaf, experienced rapid battery degradation due to lack of advanced cooling systems, with about one in twelve vehicles produced between 2011 and 2016 requiring battery replacement.
However, vehicles manufactured from 2022 onward show a dramatic improvement, with battery replacement rates dropping to just 0.3%. This progress is attributed to enhanced battery chemistry, improved battery management systems, and thermal regulation. Battery prices have also fallen by over 90% since 2010, and repair costs are becoming more affordable due to modular designs that allow component-level fixes rather than full battery replacements. Still, frequent fast charging at high power levels accelerates battery wear, reducing range twice as fast as slow charging. Other factors shortening battery life include charging to 100% regularly, leaving batteries fully depleted for extended periods, and exposure to extreme temperatures.
In the United States, EV sales have declined by 25% since early 2026 compared to the previous year, following the Trump administration's removal of subsidies and regulations that encouraged EV adoption. Despite this temporary slowdown, analysts predict that by 2030, EVs will nearly double their market share to about 11% of new car sales in the U.S. Globally, where EVs already account for 15% of sales, their share is expected to approach 25%.
