One of the issues to be solved for electric vehicles (EVs) to become a success is the technical solution of its charging system. In this paper, computational models of an inductive power transfer (IPT) system for EV battery charge are presented. Based on the fundamental principles behind IPT systems, 3 kW single phase and 22 kW three phase IPT systems for Renault ZOE are designed in MATLAB/Simulink. The results obtained based on the technical specifications of the lithium-ion battery and charger type of Renault ZOE show that the models are able to provide the total voltage required by the battery. Also, considering the charging time for each IPT model, they are capable of delivering the electricity needed to power the ZOE. In conclusion, this study shows that the designed computational IPT models may be employed as a support structure needed to effectively power any viable EV. 1. Introduction Taking into account high oil prices and environmental awareness, the development of electric vehicles (EVs) is considered as a healthier mode of transportation. This is because the electricity they consume can be generated from a wide range of sources which include fossil fuel, nuclear power and renewable sources (e.g. hydroelectricity, solar power etcetera) [1, 2]. According to [3], it was stated that inductive power transfer (IPT) systems for EV battery charge can be successful if issues such as interoperability between systems of different manufacturers, vehicle design towards effective integration of the inductive charging system, parking guidance and fundamental evaluation of the environmental impacts of the electromagnetic fields are solved. This paper focuses on the aspect of improving the efficiency of the electric power transferred to the on-board battery storage system of EVs. Regarding this aspect, several studies have been presented in [3–7]. Nonetheless, to achieve the aim of this paper, 3 kW single phase and 22 kW three phase computational IPT models for EV battery charge are designed in MATLAB/Simulink and computed based on the technical specifications of the lithium-ion battery and charger type of Renault ZOE.
