Aggressive Driving Slashes EV Battery Life
19 Aug
Summary
- Aggressive driving style significantly accelerates EV battery degradation.
- AI modeling linked driving behavior to battery wear, excluding other factors.
- Aggressive driving showed an aging rate 18.4 times higher than eco-driving.
A recent analysis by researchers at Shanghai Dianji University in China has identified aggressive driving as a key factor in premature electric vehicle (EV) battery degradation. Their study, which analyzed a year's worth of driving data from 15 EVs, utilized AI modeling to isolate the impact of driving behavior on battery wear, accounting for external influences like temperature and idling time.
The research indicated that aggressive driving styles, characterized by high electrical current demands, could result in an EV battery aging rate up to 18.4 times greater compared to smooth, economical driving. Furthermore, their battery-aging model projected a significant capacity fade of 53.22% after 1,000 cycles for aggressive drivers, versus 21.15% for those with an eco-driving style.
While the study acknowledges limitations in directly measured battery health data, the findings suggest that frequent hard acceleration and braking could substantially stress EV battery packs. The researchers concluded that optimizing driving style is an effective strategy to mitigate battery aging and extend its service life, contributing to longer EV battery lifespan.
