Imagine charging your EV at home without the need to plug it into anything. That’s precisely what Delphi Automotive and wireless energy transfer technology provider, WiTriCity, is seeking to offer – the two companies are working on developing a range of automatic wireless charging products for electric vehicles.
The wireless charging system would involve no plugs or charging cords. Drivers would simply park their electric vehicle over a wireless energy source that sits on the garage floor or embedded in a paved parking spot. The system will automatically transfer power to the battery charger that’s on the vehicle.
WiTricity’s patented wireless energy transfer technology, invented by a team of MIT physicists four years ago, 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.
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.

I dont think so this will effisien. When there is gap between 2 connectors, power will be lost.
Nope. It’s a resonant cavity. Power is transferred through induction within the resonant cavity, not electrical conduction. This is something we learn in Electrical & Electronic Engineering in the first year itself.
Nikola Tesla was the first person to come up with this idea, and there have been subsequent attempts to improve upon it. The MIT researchers who came up with it managed to make it feasible, and that’s the technology that is being used here.
this new tech kill u more faster…more radiation more harmful wave/ray….if the machine gone crazy might short circuit get u killed…
You are right Campro. Radiation from the wireless technology has become our day to day pollution. All of us can not escape from it.
Nice 1… studies of one of my assignment =)
Hope it’s will launch in Malaysia within 5 years…
there is one more thing, how about the battery life? will it sustainable ?
Never expect it come to vehicle so soon…. great approach… Well done.. MIT
Briliant Idea..When BOLEHLAND innovated our own..?Hopefully coming Soon..
that’s awesome!!!
this could be the beginning of wireless electricity :-)
Not efficient enough for long-range transmissions yet. Receiver and transmitter has to be resonant-coupled, so this limits the effective distance. Tesla proposed using the Schumann cavity as the resonant medium for global wireless electricity, but it probably won’t work because the frequency is just 8Hz, much too low for practical purposes of power transmission.
This could be the start of Fried Cat or Rat every morning when u go get your car LOL ^^
use EV vs use Petrol car.
petrol : rm hangus byr petrol
EV: rm hangus byr TNB
sama je
count la 1 km how much u pay for the electricity. want free ha? go make ur own country la.
superb and brilliant!!
I guess we’re going to implement this kind of tech once we run out of fuel, like, forever.
Again, it’s the MIT. What happened to our local unis which won lots of gold medals in international competition? Something is wrong somewhere.
Local uni have this expertise where numerous research have been conducted. But this wireless power transfer has a lot problem i.e. electromagnetic which could caused cancer. You can actually watch a lot people demonstrating the wireless power in Youtube. Yes it works but normally safe for low power demand. A lot of issues will rise in high power such as charging our EV battery. EV batteries is not a conventional 12V, it is 300V +++.
we were surrounded with microwave in our daily life. wifi, cell phone, wimax. so why not add one more.
Did you notice that all Wimax, wifi etc are data transfer not power transfer method. Thus, your judgement is invalid.
Sounds like health hazard to me. Health authorities in some countries like Germany and Sweden have issued health warning safety guidelines for low powered wireless appliances. High powered wireless device like this can only be worse. Having said that, this is the way of the future and it is likely to be part of as life as much as mobile phone transmission towers today, but we can not be ignorant of the potential health hazard of such technologies.
emm, will it charge my mobile phone if i leave it inside my car? or will it charge my brain also if I stay inside the car?
LOL..good question…but my be it must have a certain type of receiver…if not..put all your chargeable appliances in your car!!!
I have made a research before in transmitting power wirelessly in my uni days.. But there are too many issue. One of the main problem was associated with radiation. If you send power wirelessly there tends to be radiation.
We would not want to compromise our health over this would we?
How about embedding the power source resonator into the road so that the car can be charged at all time? “Charging Lane”, maybe? The charging fee transaction could be done just like the “smart tag”.
Just my 2 cent………
actually there is something similar being studied on, i remember watching a documentary quite recently, where they are studying how to harvest the sound /vibration generated by the cars moving along the road and convert into electricity.
Yeah i agree, I think this tech would complement the wireless charging.. it will be great
The Koreans have already experimented with this using buses. Implementation is slated for 2011.
“South Korea is trying a new way to turn public transport green by using a technology popular in electric toothbrushes and razors to power buses and cars.
The country’s top technology university on Tuesday unveiled a new electric transport powered by recharging strips embedded in roads that transfer energy through magnetic connections. There are no direct connections with wires.
Vehicles with sensor-driven magnetic devices on their underside suck up energy as they travel over the strips embedded a few centimeters under the road.
“The technological concept behind the idea has been around for about 100 years. We have found a better way to transfer the electricity to make it practical,” said B.K. Park, a project member at the Korea Advanced Institute of Science and Technology.”
good tech.. they should design this wireless charge with wired charging.. to the time to charge can cut 50%.. hahaha..
is it save for the vehicle occupants and everybody who’s near the car when it’s charging?
They forgot to address one major flaw. Placing something like that under the car is dangerous. Stones, rocks, mud, etc will hit it. You may spend more time replacing that thing rather than getting the benefits
I wish my notebook PC have this…….gudbye to bulky power adapter
that kind of tech is available. sadly very expensive =(
reminds me of palm pre wireless charging kit..
for long transmission …we called it ….Super conductor.
This is still one of the coolest and most brilliant new technologies yet, despite all the issues that the researchers may or may not have to resolve.
Mmm what happens if a cat went in between the resonators aa?
in future, could possibly aply on parking lots. ev cars with this tech, pay with coins on the parking lot meter maybe so while they walk around the supermarket, the car is charging at the parking lot. good tech.
