| There is a considerable interest in developing new technological systems using a renewable energy power resource. Transportation, being an industry consuming the most amount of gas, has got an extensive interest to find a green solution to empower. Electric vehicles were elected to be the top options by many researchers as a suggestion for an alternative power system of the gas energy. Many scholars have discussed the development and improvement of the electric vehicle system including the power mechanism, durability and the charging method. Initially, the plug-in charging method was adopted, however, an alternate new method which is more convenient and efficient, and less time-consuming is needed. There are several models that have been established in some regions, by embedding a wireless power transfer system into the ground surface, in order for the vehicle to be charged wirelessly, whether it is parked or moving. However, achieving adequate efficiency with a whole proper structural system is still in demand.;Dr. Mohammadreza Barzegaran and his graduate student, Mohammed Hajjaj Mahmud, have developed a new wireless power transfer system which promises to achieve 83% of efficiency with a distance of about 8 inches. It consists of two coils, namely, transmitter and receiver. To get this efficiency, there is an imperative need to develop a surface pavement cementitious material which requires appropriate conditions for electromagnetic properties of conductivity and permeability. This will allow material function to let the electric flux pass through, from the transmitter which is embedded in the ground, to the receiver in the electric vehicle. The conductive material consists of cement paste, water to cement ration being 35%, with various additive material powders including Iron, Magnetite, CNF, Copper and Nickel-Silver. After testing different ratios of mass replacement and analyzing their electromagnetic properties, two promising mixes have been selected (Iron 10% and Magnetite 20% by cement mass replacement).;The conductive layer must structurally, be very strong and should be able to carry a tire load of class 4, in the worst case scenario. To achieve this structural strength, the selected mixes have been subjected to the compressive strength test, used to simulate a finite element model in AbaqusRTM CAE. Multiple models are generated by applying different variables, the generated stresses are analyzed to create an equation relating all the variable to predict the critical tensile stresses. This can be used for designing the minimum required plate dimensions. The need for minimum thickness arises due to two main reasons; to increase the Wireless Power Transmission (WPT) efficiency the transmitter core should be kept as close as possible to the transmitter coil in the electric vehicle as well as to lower the economic cost. |
