Wireless Charging Roads [A brief Overview about Wireless Charging Roads]

How can a car get charged while moving?

A city in Canada named Detroit (Michigan) in 14th Street has made a road for charging e-vehicles while traveling on roads.*The roads produces a magnetic field which helps us recharging the cars by passing (electrons).
In US there are over 2.4 million e-vehicles running or being used.
coils are kept in road to produce magnetic field  and a receiver coil is kept in the e-vehicles to get it charge simultaneously while moving.

The main motive is to travel long with less consumption of the battery. Using this kind of method helps us to recharge our batteries in the car which leads us to travel for a long period of time.To recieve the charge from the road, a receiver coil is to be installed in the e-vehicles indeed to get it recharged.The reciever helps the current to pass to the battery directly.

To this they use the method of magnetic resonance induction ,which is the coils of copper wires in the road helps the e- vehicles to get charged by passing little amount of current sufficient to recharge the batteries of the e- vehicles.This could make the passenger to travel without being tensed of thinking for the vehicle to recharge again to continue their travel.

Now let's see what is magnetic resonance induction mean?

It is a type of wireless transfer which is done through electromagnetic  induction to the device. It is similar as the wireless charging that we do for our devices like phone and watches that we use daily.

When an electric current is sent through the coil(a woundup cable),it thus creates a magnetic field whose action creates electric current in the second coil that's some distance away.

What are the three basic components of magnetic resonance???

  • Static magnetic field
  • Radio frequency coils
  • Gradient coils

What is magnetic resonance Charing?

Resonant based-charges inject an oscillating current  into a highly resonant coil to create an electromagnetic field .A second coil with the same resonant frequency receives power from the electromagnetic field and converts it back into electric current that can be used to power and charge devices.

  1. Roadway systems: A management unit transforms power or current from the electricity grid to the in-road wireless charging coils when an authorized  vehicle is directly above an in-road segment. Communication with vehicles is managed in real time.
  2. Vehicle kit: A vehicle unit recieves the wireless energy from the wireless charging coils and transfers it to the vehicle battery.
  3. Cloud: Cloud based management software enables live monitoring and provides smart charging insights.


  1. Continuous charging-cars can charge while driving extending the range and eliminating the need for frequent shop at charging stations.
  2. Convience-users no longer need to worry about plugging into their vehicles making electric cars user-friendly and accessible.
  3. Green mobility -The integration of wireless charging promotes a shift towards sustainable and environmental friendly transportation solutions.

The technology increases the e-vehicles utilisation by reducing charging downtime and eliminating range anxiety.And the battery sizes can be minimised making e-vehicles more sustainable,cheaper and lighter with more space for passengers (or) cargo.

Future implications:       

The adoption of wireless charging roads has the potential to reshape urban planning,reduce air pollution and accelerate the transition to electric vehicles.As the technology advances and becomes more cost effective we can anticipate seeing these innovative roads becoming a common feature in smart cities

Last Words:

Wireless charging roads represent a leap towards a sustainable and connected future . Embacing this technology not only transforms  the way we charge electric vehicles but also paves the way a cleaner and more efficient transportation ecosystem.
