Increasing Effective Range of Electric Vehicles Using Electromagnetic Induction

Overview

Objectives/Goals Using fossil fuel in vehicles significantly harms our environment by releasing about 1.5 Billion metric tons of CO2 and many other poisonous gasses into the atmosphere every year. Plug-in Electric Vehicle (PEV) can help alleviate these problems. However, the adoption of PEVs has been slow as the vehicle range is limited by its battery size. The objective of this experiment is to demonstrate the possibility of wirelessly charging PEVs while driving along highways using Electromagnetic Induction technology. As a result of this, PEVs will have a much longer range without any additional cost and that would lead to faster adoption. It is a Win-Win proposal for the environment, our long-term health, and the overall economy Methods/Materials We used a model track, an electromagnetic transmitter, an electromagnetic receiver, a car chassis, and an oscilloscope to demonstrate electricity transmission from the track to the car without wires. We also measured the frequency of change of the magnetic flux and the amplitude of the generated voltage. Results We demonstrated that electricity can be transmitted from the road to the car without wires. The efficiency of the voltage generated in the receiver was measured by changing the number of coils and the distance between the transmitter and the receiver. Conclusions/Discussion My tests have shown that wireless charging for electric cars is a viable option. Further enhancements have to be made for safety and efficiency before it is ready for commercial usage.
