In order to meet cost targets for hybrid electric (HEV), Plug-in hybrid electric (PHEV), and allelectric vehicles (EV), an improvement in the battery life cycle and safety is essential. One practical approach to improve performance is to use power electronics intensive cell equalizer, in conjunction with on-board energy storage devices. A new technique based on buck-boost topology to equalize a...

An impedance-based temperature estimation method is investigated considering the electrochemical non-equilibrium with short-term relaxation time for facilitating the vehicular application. Generally, sufficient relaxation time is required for battery electrochemical equilibrium before the impedance measurement. A detailed experiment is performed to investigate the regularity of the battery impe...

To ensure safe and reliable battery operations, an accurate battery state of charge (SOC) estimation is critical for the battery systems used in electric vehicles and hybrid electric vehicles because of the arduous operation conditions. This paper presents a SOC estimator designed based on the unscented Kalman filter (UKF), which is very popular in the state estimation in non-linear systems. Th...

This article addresses a new network equilibrium problem with mode and route choices for the emerging need of modeling regional transportation networks that accommodate both gasoline and electric vehicles. The two transportation modes (or vehicle types) distinguish from each other in terms of driving distance limit and travel cost composition. In view of the advantages (e.g., low fuel expenses ...

Battery degradation is a main concern for electric vehicle (EV) users, and reliable capacity estimation of major importance. Every EV battery management system (BMS) provides variety information, including measured current voltage, estimated the battery. However, these estimations are not transparent manufacturer-specific, although measurement accuracy unknown. This article uses extensive measu...
