Researchers have developed a new physics-informed machine learning framework that uses virtual sensing to assess the health and design of lithium-ion batteries. This approach infers hard-to-measure parameters like diffusion coefficients and electrode thickness from standard battery management system data. The framework significantly reduces prediction errors for battery lifespan and capacity loss, enabling a continuous feedback loop between real-world operation and upstream design decisions. AI
IMPACT Enables more accurate battery lifespan prediction and informs design decisions, potentially accelerating the development of better batteries for EVs and grid storage.
