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 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 natio glide on eyeshadow stick on battery state evaluation and RUL prediction methods, and proposed a variety of methods.This paper first introduced the definition of SOC and 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 us polo assn mens sweaters lithium-ion battery state estimation and RUL prediction were summarized, and the future development direction was proposed.
