Model for predicting battery RUL

A new way to model the lifetime of batteries has been developed by researchers in China, writes Nick Flaherty. Accurate prediction of the remaining useful life (RUL) of a battery – as in the number of cycles left before this failure point – is essential for proactive battery management, preventing unexpected failures, optimising replacement schedules, and reducing costs and safety risks in real-world applications.
