Abstract In order to accurately estimate the state of health (SOH) of lithium-ion batteries, this paper proposes a new estimation method based on improved grid search (GS) and generalized regression neural network (GRNN). Firstly, data processing is performed on the data set, and effective characteristic data including voltage and current are extracted through correlation analysis method. Secondly, a regression model based on improved grid search and generalized regression neural network is proposed to estimate the health of the battery. Finally, two public data sets of lithium-ion batteries are used to verify the proposed estimation method. Experimental results prove that this method has the advantages of accuracy, generalization performance and reliability compared with other estimation methods.

Key words： lithium-ion battery state of health (SOH) feature extraction generalized regression neural network (GRNN) hybrid algorithm
