Scientists Just Discovered A Secret To Make Your EV Battery Live Years Longer

"Frequent fast charging can accelerate a lithium-ion battery's aging. Researchers in Sweden found a way to use artificial intelligence to slow degradation. The simulation results are impressive, and could make a huge difference if commercialized. Artificial intelligence is already seeping into cars, with the technology now embedded into everything from autonomous vehicles to voice assistants."

"Researchers at the Swedish Chalmers University of Technology said in a study published in the academic journal IEEE that they had developed an AI-based charging method that can optimize the current during fast-charging cycles, and extend the vehicle's battery life by as much as 23%. That number is huge, representing nearly a quarter of the battery's lifespan."

""This work introduces the first explicit formulation of a lifelong battery fast charging problem, authors Meng Yuan and Changfu Zou from Chalmers University's Department of Electrical Engineering wrote in the study. The proposed method achieves a significant improvement in performance, where battery lifespan is extended to 703 equivalent full cycles... representing a 22.9% improvement over the standard baseline."

"While modern EV batteries are already designed to last for years without defects or significant degradation, frequent fast-charging can accelerate aging. High-powered charging can stress the components inside the cells, potentially causing"

Frequent fast charging accelerates lithium-ion battery aging by stressing internal cell components. Researchers at Chalmers University of Technology developed an AI-based charging method that optimizes charging current during fast-charging cycles. The approach targets the lifelong battery fast charging problem by improving performance across the battery’s usable life. Simulation results show battery lifespan extended to 703 equivalent full cycles, representing a 22.9% improvement over a standard baseline. The improvement corresponds to nearly a quarter more lifespan, which can translate into tens of thousands of additional miles depending on driving and charging patterns. The method is framed in terms of charge/discharge cycles rather than calendar time.
