Review on State Estimation and Remaining Useful Life Prediction Methods for Lithium-ion Battery

Blog Article

Accurate estimation of state of charge (SOC), battery state of health (SOH) and prediction of battery remaining useful life (RUL) of lithium-ion battery are important contents Apparel of battery management.It is of great significance to prolong battery life and ensure the reliability of battery system.Researchers all over the world have done a lot of research on battery state evaluation and RUL prediction methods, and proposed a variety of methods.This paper first introduced the definition of SOC and 6.64/6RC SOH and the existing estimation methods and compared them.

Then, the definition of RUL was introduced and the main methods were classified and compared.Finally, the challenges of lithium-ion battery state estimation and RUL prediction were summarized, and the future development direction was proposed.
