In-pavement Charging for Electric Vehicles to Reduce Air Pollution

This proposal aims to develop an in-pavement charging system for electric vehicles that can offset the shortage of charging stations. The newly developed system will not only promote the usages of electric vehicles to reduce gas emission, but also provides a solution to public transportation to those vulnerable communities. Very recently, inductive or wireless charging technology emerged. This new technology requires both infrastructure investment and vehicle investment. To make wireless charging happen, a flat transmitter pad on the floor connected to power station is needed as a power supply to the electric vehicle, and a rectifier on the bottom of the electric vehicle need to be preinstalled as a receiver to receive and convert the energy to recharge the battery. Even though this inductive charging technology wiped off wired charging, it still needs an electric vehicle to be charged under a “stop” motion. This may not meet the needs of public transportation, while city buses need to be charged more often due to high power consumption and commute interruption due to “charging” needs are not practical. A solution to solve the charging needs for public transportation can be in-pavement charging while driving. The magnetic field created by a high-frequency alternate current is picked up by a compatible coil on an electric vehicle. During driving, the receiver installed at the bottom of the electric vehicle converts the magnetic field back to electricity to power the motor directly to save the battery use or it can also be used to recharge the battery. This proposal aims to develop a magnetizable concrete, which not only can be used as a concrete cover to protect those embedded coils but can also be part of the charging system to amplify magnetic energy to improve the charging efficiency of the in-pavement charging system as a whole. Unlike a traditional smart pavement that uses pressure or high temperature to generate energy, the magnetizable concrete is a highly permeable material consisting of ferrite and cement.
