Witricity Ev Wireless Charging: Watch: What wireless charging an EV looks like, technology explained – Times of India

With the growing emphasis on expanding EV charging infrastructure across the globe, a US-based technology company is bringing the convenience of wireless charging to owners of electric vehicles. WiTricity has developed wireless charging stations and a technology solution that can be built into electric cars to support wireless charging, similar to what we regularly see in smartphones. In a video released by the company, we can see a 2018 Tesla Model 3 EV park in front of a WiTricity public charger and begin charging without any physical connection. While the Model 3 does not get any wireless charging capability, it has been fitted with WiTricity’s charging solution which enables the function for the EV. Watch the video here.

As we just saw, the EV parked in front of a generic looking charging point, the only difference was the presence of a square pad placed on the ground. The wireless charging technology developed by WiTricity, uses magnetic resonance to facilitate the transfer of power between a charging point and an EV. It includes two resonator devices, a source resonator (charging pad placed on the groundt) and a device resonator (built into the EV), the system works on the principal of resonant coupling. Resonant coupling occurs when the natural frequencies of the two systems, a source and a receiver, are approximately the same. The system’s specially designed magnetic resonators are able to transfer power to an EV based on this principal.

The company claims that unlike typical smartphone wireless charging which takes longer and is not as efficient, their wireless charging system for EVs is just as fast ans efficient as a cable charging setup. Wireless charging an EV also introduces several other benefits such as easier maintenance, as there are no physical moving parts. All weather usage, lower utility cost, increased safety and space conservation are also among benefits of the system. The company is currently working on onboarding EV OEMs to integrate the technology in upcoming EV models.

Would you be more likely to invest in an EV if it has wireless charging? Let us know your thoughts in the comments.
