Recent studies indicate that electric vehicle (EV) batteries are likely to outlast the vehicles themselves, contradicting previous fears about battery longevity. Data from Geotab shows that the average degradation rate of EV batteries has improved from 2.3% to 1.8% per year, with many batteries potentially lasting over 20 years. This improvement is attributed to better management practices and advancements in battery technology. Environmental factors, such as temperature and charging methods, are critical in influencing battery lifespan, with fast charging linked to accelerated degradation. Additionally, research is ongoing to enhance battery performance, including studies on lithium iron phosphate batteries, which face challenges related to ion movement. Overall, EV battery health remains robust, with many retaining over 80% of their capacity after 12 years.
