Wireless charging for electric cars represents one of the most promising innovations in the electric mobility sector. This technology offers a practical and efficient solution for charging vehicles without the need for cables or physical connectors.
Wireless charging for electric cars: how does it work?
Wireless charging for electric cars is based on the principle of electromagnetic induction: a transmission system, installed under the road surface or on the floor of a parking lot, generates a magnetic field that is picked up by a receiver built into the vehicle, transforming it into electricity for the battery.
To start charging, the driver simply parks the car on top of the charging plate, ensuring that the automatic alignment system confirms correct positioning.
Some more advanced models use communications between the vehicle and the station to optimize energy transfer and improve efficiency.
Currently, the efficiency of wireless charging varies between85 percent and 95 percent, values that are increasingly close to those of wired systems, making it a promising solution for the future of electric mobility.
In fact, the operation is not far removed from wireless charging technologies already in use on devices such as smarthones and the like.
Current state of technology
Currently, several pilot projects have been initiated around the world to test this innovative technology. Companies such as WiTricity and Qualcomm are working on systems that use electromagnetic fields to transfer energy between a fixed base, installed on the floor, and the vehicle itself equipped with specialized receivers.
In Italy, among several names, start-up Silla Industries presented Prism AIR, a pilot technology that allows electric cars to be charged wirelessly, without the need to connect the car to a cable.
Advantages of wireless charging for electric cars
The main advantages of wireless charging include:
- Convenience: users do not have to worry about the physical connection of the cable; just park over the compatible location.
- Continuous charging: the possibility of installing wireless systems in public areas or company parking lots could enable continuous charging during short stops.
- Reduced wear and tear: eliminating the need for physical cables also reduces wear and tear on charging connections and ports in vehicles.
Challenges and timing of commercialization
Although technological advances are promising, there are still some challenges to overcome before this technology can be commercialized on a large scale:
- Costs: Currently, wireless systems are significantly more expensive than traditional charging stations; these costs will need to be reduced in order to make them accessible to the general public.
- Standardization: lack of common standards could hinder development; creating shared protocols among different manufacturers will be crucial.
- Infrastructure: the installation of fixed bases will require significant investment in existing urban infrastructure.
Forecasts indicate that it will be a few more years before wireless charging stations are widely available in the market; however, developers are optimistic that this technology could become mainstream by the end of the current decade.

Future evolution and sustainability
Another crucial aspect of wireless charging is its potential contribution to environmental sustainability. Adoption of this technology could reduce the environmental impact associated with the production and consumption of traditional cables and connectors.
In addition, integration with renewable energy systems, such as solar panels or smart grids, could make charging even greener. When combined with shared mobility solutions, wireless charging could accelerate the transition to more sustainable cities that are less dependent on fossil fuels.
Conclusions
In conclusion, although wireless charging stations for electric cars are the epitome of an exciting future in electric mobility due to their practicality and potential efficiency, significant challenges remain to be addressed before their large-scale commercial deployment.
