Abstract
Battery operated electric vehicles are attracting many users. Utilisations of EV are day by day increasing and hence there is need to enhance the entire performance of EV by designing the best internal parameters of battery used in subsystems of EV. The entire performance of battery is depending upon the various factors of battery such as specific energy, life cycle, safety, internal resistances, charge and discharge time, temperature, cost and toxicity. The main objective this research paper is to study and analyse the electric circuit model (ECM) of battery that in EV to find the internal parameters by using algorithm. The various models of ECM such as simple model, enhanced simple model, dynamic model, Thevenin-based model, modified generic model and Tremblay model are critically reviewed. The Thevenin model is best suitable for simulation of battery for SoC, SoP, etc. from predefined value of resistances and capacitor.
