A team of researchers has developed a new framework called D2B (Driving to Battery) that integrates transportation scenarios with electric vehicle energy systems to quantify the impact of driving behavior on battery health. The study, published in Communications in Transportation Research, found that more stable driving behavior can extend battery lifetime by approximately 10% over a 10-year period, while high-intensity travel demand like ride-hailing can lead to comparable battery degradation in as little as five years.

Why it matters

As electric vehicle adoption continues to grow, understanding the real-world factors that affect battery performance and longevity is crucial for strengthening consumer confidence and supporting the transition to sustainable transportation. This research provides a reliable, interpretable framework for assessing battery health based on driving patterns and travel demand, enabling better decision-making around battery management, insurance pricing, and eco-driving algorithms.

The details

The D2B framework combines a physics-based powertrain model with the CARLA traffic simulation platform to dynamically evaluate how driving behavior affects battery aging and energy consumption. Using deep reinforcement learning, the researchers developed driving style models that optimize for battery health and energy efficiency while meeting safety constraints. The framework was validated across multiple scenarios using private vehicle data from Los Angeles and New England, as well as ride-hailing data from Guangzhou, China.

  • The study was published in April 2026 in Communications in Transportation Research.
  • The D2B framework was developed over the past two years by a research team at the School of Future Technology at South China University of Technology.
