AI-Optimized Charging Boosts EV Battery Lifespan by 23% Without Adding Charge Time

Researchers at Chalmers University of Technology in Sweden have developed an artificial intelligence-based charging strategy that dynamically adjusts the fast-charging process according to the health status and chemical characteristics of electric vehicle (EV) batteries. This method extends battery lifespan by nearly 23% without increasing total charging time. The technology can be deployed simply by updating the vehicle's battery management software, making it compatible with existing EVs. Currently, EV batteries are expected to last between 8 and 15 years, depending on usage conditions. While fast charging is essential for heavy-duty vehicle operators, taxi drivers, and long-distance drivers, frequent use accelerates battery degradation. The new approach employs reinforcement learning to enable adaptive charging control, thereby reducing stress on the battery.
