Go easy on the gas —new study suggests a smooth EV driving style is simplest way to prolong its battery life
Research suggests 'aggressive' drivers could be wearing out their EV batteries faster
Researchers from Shanghai Dianji University in China have discovered that aggressive driving habits can lead to premature degradation of electric vehicle (EV) batteries. By analyzing a year's worth of driving data from 15 EVs in Guangzhou during 2022, they found that optimizing driving style is an effective way to prolong battery life.
They developed AI models to link driving styles to battery wear, separating driving behavior from factors like temperature and state of charge. The most aggressive driving style produced a battery aging rate 18.4 times higher than the most economical driving style, leading to a 53.22% capacity fade after 1,000 cycles compared to 21.15% for the most economical.
While other factors may contribute to battery degradation, such as charging habits and vehicle load, this study suggests that smoother driving can help extend the life of EV batteries and improve long-term health.
