Research on State of Health of Power Battery Assessment Model Based on New Energy Vehicle Operation Data Analysis

To solve the problem of difficulty in evaluating the battery health status (SOH) of new energy vehicles, a novel model is established in this paper based on new energy vehicle operating data and verified itself for battery health status. This paper first pre-processed the new energy vehicle operating data, then analyzed and determined the related characteristic parameters on processed data, then proposed a multiple regression analysis modeling of SOH, finally this paper verified the accuracy of the model and indicate that the error is within the acceptable range which this novel model has certain guidance and technical support.
