A review of traction battery model and parameter identification in electric vehicle

Abstract

State estimation is a key issue of battery management system (BMS) to improve the energy utilization of traction battery in electric vehicle, which is usually achieved based on battery model. The commonly used models, equivalent circuit model (ECM) and electrochemical mechanism-based model (EMM), are reviewed in this paper. Besides, the corresponding parameter identification methods are analysed considering the target application background.
