Go easy on the gas — new study suggests a smooth EV driving style is simplest way to prolong its battery life
- New analysis links aggressive driving to premature EV battery degradation
- Chinese researchers found optimizing driving style can prolong battery life
- Researchers used AI modeling to link driving style to battery wear
Researchers at Shanghai Dianji University in China have linked aggressive driving styles to premature EV battery degradation, concluding that optimizing driving style is an “effective way to alleviate the aging of power batteries and extend cycle life”.
The researchers pored over a year’s worth of driving data from 15 EVs in Guangzhou during 2022, gathering data every 10 seconds on metrics such as speed, current and state of charge to determine the overall smoothness of acceleration and deceleration, as well as the overall intensity of driving.
Once gathered, the data was compiled to create profiles, with the smoothest category dubbed ‘eco-driving’ and the most aggressive category housing those scenarios where the vehicle was pulling very high electrical current from...
