Estimation of State of Charge of Batteries for Electric Vehicles
State of charge (SOC) can be applied in various fields characterized as an important parameter for estimating residual capacity state of battery. It is obtained from current or collected data, such as voltage, current and temperature as well. The accuracy of estimation of SOC of power battery can be essential and premise in designing the battery management system. Researchers in the fields shal...
متن کاملState of charge estimation for electric vehicle batteries using unscented kalman filtering
0026-2714/$ see front matter 2012 Elsevier Ltd. A http://dx.doi.org/10.1016/j.microrel.2012.11.010 ⇑ Corresponding author. E-mail address: [email protected] (M. Pecht). Due to the increasing concern over global warming and fossil fuel depletion, it is expected that electric vehicles powered by lithium batteries will become more common over the next decade. However, there are still some unreso...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولFast Estimation of State of Charge for Lithium-Ion Batteries
This paper presents a novel impedance-based approach to efficiently estimate the state of charge (SOC) of a Li-ion battery. By using an AC impedance analyzer, a database is constructed, containing records of AC impedance versus SOC. In practical applications, the SOC values can be found instantly once the contents of the database are referenced. For validation purposes, AC impedance comparisons...
متن کاملRobust State of Charge Estimation for Hybrid Electric Vehicles: Framework and Algorithms
State of Charge (SoC) estimation is one of the most significant and difficult techniques to promote the commercialization of electric vehicles (EVs). Suffering from various interference in vehicle driving environment and model uncertainties due to the strong time-variant property and inconsistency of batteries, the existing typical SoC estimators such as coulomb counting and extended Kalman fil...
