“…However, the cruising range of EVs is currently limited due to the necessity of recharging their batteries periodically. Improving the battery's power density and adopting advanced technologies such as plug-in hybrids and fuel cell vehicles are among the approaches proposed for extending the cruising EVS27 International Battery, Hybrid and Fuel Cell Electric Vehicle Symposium 2 range [1][2][3][4]. Among these technologies, a wireless dynamic charging system can charge EV batteries while the vehicles are moving and thereby greatly extend their cruising range [5].…”

The cruising range of an electric vehicle (EV) can be greatly extended by a dynamic wireless charging system because the battery can be charged while the vehicle is moving. However, the investment in infrastructure can be enormous and has to be reduced to implement the system. This paper presents the design of a wireless power transfer system with road embedded transmitter coils to facilitate dynamic charging of EVs. A 30 cm by 1.6 m transmitter coil, which is relatively long compared with the 40-cmdiameter circular receiver coil, has been designed to reduce the cost of the transmitter circuit. A prototype transmitter coil has been embedded into a road for evaluation of its characteristics. The measured coupling coefficient of the transmitter and receiver coils is as small as 0.09 because of the asymmetry between the coils. Compensation circuits for the transmitter and receiver coils have been designed and optimized for such a small coupling coefficient condition. The designed dynamic charging system can transfer more than 1 kW of electric power with more than 90% efficiency. Five transmitter circuits have been embedded into a road surface for testing. Cement asphalt mortar was used to construct the road surface in this study to avoid damaging the transmitter coils by high temperature and high pressure during the construction work. The designed receiver circuit has been installed on a compact 2-seater EV. A demonstration was conducted to show that the retrofitted EV can successfully receive electric power transferred from the road.

“…Gregory L. Plett et al [6] studied the application of boron phosphate batteries on E-REV and conducted a research on the control strategy of the battery energy management. In addition, Matthew Doude, YiminGao et al [7][8][9] studied the matching methods of the E-REV and conducted a simulation test by the tool of hardware-in-the-loop (HIL) such as DSPACE.…”

In order to improve the dynamic performance and endurance mileage of vehicle, operation mode and parameter matching were analyzed and designed on a novel power transmission scheme of range-extended electric vehicle (R-EEV), and the following control strategy of the engine optimization curve was proposed. The simulation was carried out on the Matlab/Simulink software platform and the results showed that the matching parameters and the control strategy of engine were both reasonable, the dynamic performance improved and the vehicle could be operated efficiently.
