<ul data-eligibleForWebStory="false">Researchers at NREL have developed a physics-informed neural network model to predict battery health faster than traditional models.The AI-based model separates a battery’s internal properties from its output voltage, allowing for quicker battery degradation diagnosis.The study in the Journal of Energy Storage shows that the model can estimate battery lifespan changes during aging and adapt to different scenarios.The NREL researchers aim to validate the model with real-world data and enhance its accuracy for broader internal battery parameter prediction.
