Surface Temperature Assisted State of Charge Estimation for Retired Power Batteries

Surface Temperature Assisted State of Charge Estimation for Retired Power Batteries

Accurate State of Charge (SOC) estimation for retired power batteries remains a critical challenge due to their degraded electrochemical properties and heterogeneous aging mechanisms. Traditional methods relying solely on electrical parameters (e.g., voltage and current) exhibit significant errors,...
