Shanghai Dianji University study: Aggressive driving accelerates EV battery aging

Researchers at Shanghai Dianji University have found that aggressive driving styles can cause electric vehicle batteries to age up to 2.5 times faster than eco-friendly driving styles.

By analyzing data from 15 electric vehicles used in various environments—including cities, rural areas, and highways—over a one-year period, the study tracked metrics such as speed, voltage, state of charge, and temperature. The researchers categorized driving into five distinct styles. Their findings indicate that aggressive driving, characterized by frequent rapid acceleration at low speeds or heavy braking at high speeds, significantly increases battery stress. In extreme cases, the stress applied to the battery was measured to be as high as 18.4 times greater than in standard driving conditions.
