Experimental Design of Solar Powered Dynamic Wireless Charging of Electric Vehicle

Nowadays, electric vehicle (EV) and solar systems are an emerging technology in area of transportation and energy source, respectively. The major issue of EV system is battery storage and charging system. In this paper, design of a low cost wireless power transfer based dynamic wireless power transfer (DWPT) based charging system with solar system as a input DC source is presented. In an EV, the in-motion battery charging system may reduce the overall size of the battery and also increase the driving distance. In the dynamic charging system, the major drawback as that optimal use of the transmitting power based on the position of the vehicle. In this work, a low cost solution is presented to optimize the performance of the transmitting coil and DC power source. To minimize the cost of the system, a multi channel relay, IR receiver sensor is used in power transmitting track and IR transmitter sensor is connected in the vehicle. A cost effective NodeM Cu(esp8266) is used to provide the switching pulses to DWPT circuit. A complete experimental design approach of DWPT system is discussed in this paper.
