Wireless charging for electric vehicles (EVs) has transformed the way we power our automobiles, providing the same convenience and efficiency as wireless charging for smartphones. This technology, which is based on resonant electromagnetic induction, is gaining popularity around the world, with market growth expected to be significant in coming years. This article explores the the workings of wireless EV charging, its benefits, infrastructure costsand the future of Wireless Electric Vehicle EV charging.
How Wireless EV Charging Works
Wireless EV charging makes use of resonant electromagnetic induction, which is similar to how cellphones charge wirelessly. A magnetic coil in the charger sends current to a coil on the underside of the EV. When the two coils align, charging begins. This method is as efficient as plug-in charging, with wireless chargers reaching 90–93% efficiency, which is comparable to regular EV plugs. Wireless charging can produce up to 20kW of power, which is similar to Level 2 charging speeds, with the possibility of faster speeds in the future.
Wireless EV Charging Options
There are two types of wireless EV charging: static and dynamic. Static charging is comparable to regular charging in that the EV remains stationary during charging. Dynamic charging, on the other hand, is intended for on-the-go charging and will be integrated into roadways, allowing EVs to charge while driving. This technology has the potential to completely change long-distance driving for electric vehicle owners by eliminating the need for frequent recharging breaks.
Benefits of Wireless EV Charging
Wireless EV charging offers several advantages over traditional plug-in charging. The most significant benefit is the elimination of charging cables, reducing the risk of damage and improving safety. Wireless charging also provides greater convenience, as EV owners no longer need to manually plug in their vehicles. Additionally, wireless charging saves time, as the process is automated and does not require the driver to exit the vehicle.
Wireless EV Charging Infrastructure Costs
The cost of wireless EV charging infrastructure varies depending on the provider and installation requirements. Plugless Power, a leading supplier of wireless charging solutions, offers a third-generation wireless charger for approximately $3,500, excluding installation costs. As the market expands and competition increases, the cost of wireless charging infrastructure is expected to decrease, making it more accessible to EV owners.
The Future of Wireless EV Charging
Wireless EV charging has a hopeful future, thanks to technological and infrastructure developments that are pushing global adoption. As more EV models are fitted for wireless charging and infrastructure expands, wireless EV charging is positioned to become the norm for electric car charging. With the potential for dynamic charging integrated into highways, the future of wireless EV charging offers exciting opportunities for both the automobile industry and EV owners.
Wireless EV charging is transforming the way we charge electric vehicles by providing convenience, efficiency, and safety advantages over standard plug-in charging. While usage in the UK continues to grow, advances in technology and infrastructure are paving the way for widespread use. As more EV models are fitted for wireless charging and infrastructure expands, wireless EV charging is poised to become the norm, transforming the automobile industry and improving the driving experience for EV owners worldwide.
