Wireless charging is kicking in yo!

Now this is what I call unplug! Driving a super environment friendly electric car, and don’t have to worry about insufficient electric for your new EV. Drive home, flip the switch, and you’re ready for dinner. That’s a very cool invention from WiTriCity, a pioneer in wireless energy transfer technology, and Delphi Automotive. That’s the result of the collaboration between the two companies that are working on developing a range of automatic wireless charging products for electric vehicles.

No additional plugs or charging cords are needed in the wireless charging system. All the driver need to do is to simply park their electric vehicles over a wireless energy source that sits on the garage floor or embedded in a paved parking spot, and the system will automatically charge up your car once you activate it.



This patented wireless energy transfer technology is invented by Nikola Tesla, and improved by a team of MIT physicists since four years ago to make it feasible. The technology makes use of highly resonant magnetic coupling, offering a transfer of over 3,300 watts – enough to fully charge an electric car at the same rate as most residential plug-in chargers. The system can efficiently transfer power over significantly larger distances and allow more parking-related vehicle misalignment than inductive systems. Ask any E&E Engineering student, and they should be able to explain better to you than me, what resonant cavity is. Despite the gap, no power would be lost as power is transferred through induction within the resonant cavity, not electrical conduction.

However, wireless charging technology will of course need to co-exist with plug-in charging solutions, the company states, so that electric vehicle drivers have the ability to charge their vehicle with something like Delphi’s portable electric charger – which fits into any standard AC outlet – when they’re away from their wireless charging source. This is actually a much refined package, by offering the wireless energy transfer package as an add-on instead of a standalone device. Sometimes we just can’t park properly. Well, now you have a better reason to buy an EV!
