Aggressive Driving Significantly Accelerates EV Battery Degradation, Study Finds
A recent study conducted by researchers at Shanghai Dianji University in China has revealed that aggressive driving styles can cause electric vehicle (EV) batteries to degrade 2.5 times faster than eco-friendly driving. The findings, published in Scientific Reports, indicate that hard acceleration and deceleration, along with excessive demands on battery current, are primary contributors to this accelerated aging. The research team analyzed a full year of real driving data from 15 EVs in Guangzhou in 2022, recording usage data every 10 seconds across typical urban, suburban, and highway conditions. This data was then fed into a battery-aging model to predict capacity loss over 1,000 charge-discharge cycles. The study found that the smoothest driving style resulted in a 21.15 percent loss of maximum battery capacity, while the most aggressive style led to a substantial 53.22 percent loss.
