The automotive industry is experiencing a seismic shift as the world embraces electric vehicles (EVs) in an effort to reduce carbon emissions and create a more sustainable transportation landscape. As automakers race to innovate and overcome the challenges associated with EVs, Ford has taken a bold step forward with a recent patent that envisions a novel solution to charging electric vehicles – in-road wireless charging technology.

This innovative concept, revealed through a patent granted by the United States Patent and Trademark Office (USPTO), showcases Ford’s vision for the future of EV charging. The patent application, titled “Roadway Charging Coil Alignment and Monitoring,” outlines a system wherein coils connected to a power source are embedded into the road surface. These coils are designed to transmit power wirelessly to receivers mounted on electric vehicles as they travel along the road.

The concept introduces an intriguing solution that could potentially revolutionize the way electric vehicles are powered. By harnessing the power of wireless charging integrated directly into roadways, the need for conventional charging stations could be reduced, enabling EVs to charge on the go. This could lead to a fundamental transformation in the design and efficiency of electric vehicles, with the possibility of smaller batteries resulting in lighter and more agile cars.

One of the key innovations proposed in the patent is the use of ground-penetrating radar equipped on the EVs. This radar system would detect the embedded coils in the road and guide the vehicle to align precisely with the coils. This alignment optimization aims to maximize the charging efficiency by ensuring a strong connection between the in-road coils and the vehicle’s receiver.

However, as with any groundbreaking idea, Ford’s in-road wireless charging technology is not without its challenges and considerations. One of the primary concerns revolves around the potential costs associated with the implementation of such a system. The infrastructure required to embed coils in roadways, along with the necessary power supply and maintenance, could pose a significant financial burden. The feasibility of deploying this technology on a large scale would depend on striking a balance between cost-effectiveness and the benefits it offers.

Furthermore, the current limitations of dynamic wireless charging solutions are worth noting. Most existing systems offer power outputs ranging from 11 to 20 kilowatts, which are still in the experimental stages. Although advancements have been made, higher power transfer rates are required to match the convenience and speed of conventional charging methods. 

Ford’s pursuit of innovative EV technologies is not limited to in-road wireless charging. The company has recently obtained patents for other advancements, such as a portable charging trailer capable of powering the towing EV and a roof-mounted backup battery pack. These endeavors underscore Ford’s commitment to shaping the future of electric mobility.


In conclusion, Ford’s patent for in-road wireless charging technology represents a significant stride toward transforming the electric vehicle landscape. While the concept presents promising possibilities, challenges related to infrastructure costs and power transfer efficiency must be addressed. As the automotive industry continues its journey toward a greener future, innovations like in-road wireless charging could play a pivotal role in defining the next generation of electric vehicles and reshaping the way we think about EV charging.
