Summary: This paper proposes a co-estimation framework utilizing the advantages of both recursive least squares (RLS) and recursive total least squares (RTLS) for a higher parameter identification performance of the battery equivalent circuit model (ECM). RLS quickly converges by updating the parameters along the gradient of the cost function, while RTLS is applied to attenuate the noise effect once the parameters have converged. Both simulation and experimental results show that the proposed method has good accuracy, a fast convergence rate, and robustness against noise corruption.

Summary: This study experimentally investigates the degradation of electric vehicle lithium-ion batteries (LIBs) at different temperatures and discharge rates, and proposes a new degradation model to more accurately predict the capacity degradation of EV LIBs. The research reveals that the available capacity of LIBs transiently increases with the increase of charge-discharge cycles during the initial stage of battery use. Temperature has a significant impact on the available capacity of LIBs, and alternating changes in ambient temperature can accelerate the degradation of LIBs. The proposed degradation model exhibits higher prediction accuracy compared to the traditional model.
