Abstract: One of the main challenges in lithium-ion battery diagnostics is the absence of sensors directly measuring the health of the battery during operation. This parameter can be estimated from voltage and current measurements, employing differential voltage or incremental capacity analyses. However, this estimation is often challenging in real-world applications because the shape of the differential voltage and incremental capacity curves changes with increasing current rates, and some key features in the curves vanish, affecting the applicability of the method.
