Charging Ahead: Exploring Wireless EV Charging Solutions in North America

The article by Amna Mumtaz, Analyst at PTR Inc. highlights that the wireless or inductive EV charging contains the potential to revolutionize EV charging infrastructure; however, the technology is in its early stages. It operates through a charging pad and receiver beneath the car, transferring power when coils align. Unlike wireless phone charging, EV systems can function with a distance of up to 10 inches. There are two types of wireless EV charging technologies including static and dynamic wireless charging. Static charging utilizes stationary pads, either on the ground or embedded in infrastructure, allowing EVs to charge while parked. This method is convenient for overnight charging or during extended periods of parking, eliminating the hassle of manual plugging. Dynamic charging, on the other hand, integrates charging infrastructure directly into roadways, enabling EVs to charge while in motion. This innovation maintains a continuous charge, even at speeds of up to 65 mph, potentially extending the range of EVs and minimizing the need for large battery packs.

The wireless EV charging sector in North America is gaining momentum. Partnerships between companies like WAVE Charging and public transit agencies, as well as initiatives from startups like HEVO, highlight the diverse efforts to bring wireless charging to mainstream consumer vehicles. The Charging Interface Initiative organization (CharIN) has established a Wireless Power Transfer Taskforce to standardize and facilitate seamless wireless charging experiences.  In North America, EV sales and environmental consciousness are expected to further boost demand for eco-friendly wireless charging solutions in the region.
