Although a plug-in electric car has its advantages, some suppliers are betting that not all EV owners will want to plug in. Some, they say, will want to charge their cars wirelessly.
Today, the market for wireless car charging is small and moving slowly. A few manufacturers are working on internal projects, while others are talking with suppliers. Still, one study from RnRMarketResearch.com predicts rapid adoption of the technology, with total market size reaching $4.6 billion by 2019. ”We’re talking to a lot of auto manufacturers right now who are interested in the technology,” Lacy Heiberger, marketing manager for Evatran, told Design News.
We’ve collected photos and graphics of some of the newest charging pads for electric vehicle batteries, along with a couple systems targeted at charging of consumer devices in the car. From suppliers large and small, we offer a peek at what’s coming.

The Plugless system from Evatran uses inductive technology to transfer power wirelessly. When the Parking Pad on the ground aligns with the Vehicle Adaptor (installed on the vehicle’s undercarriage) the system awakens and automatically transfers energy across an air gap at power level consistent with those of a Level 2 charger.

E007, Lazy or "luxury"? Or just plain not competent enough to be able to get the car plugged in correctly. There is a whole class of people unable to change a light bulb without getting it cross-threaded. And anothe bunch of people who see no problem at all with that. The lack of any skill and understanding is quite likely what will bring about the end of our great country, which while true is certainly a terrible way to go.
It will either become outlawed or people will realize the inefficiency of this process and quit using it. There are always optimists that are looking to make a quick buck off of lazy people. With phones I guess it's acceptable because of the low amount of energy exchanging hands but with a car where thousands of kWh is drawn I would consider a more efficient way.
The issue of undesirable heath effects is still up for grabs and will of course depend on how much of that radiated power is NOT recovered. None of the power that goes into charging the batteries is a problem, but all of the lost power could certainly be a problem.
BUT as the proponents of wireless charging of all kinds of things keep teling us how wonderful it is, THEY NEVER EVER TALK ABOUT ACTUAL EFFICIENCY, except possibly in some of the most confusing doubl-speak that I have ever come across. A Normal expression of efficiency, power out / power in is all that I am asking for and that should not be so very challenging to calculate. My feeling is that the efficiency is so very poor that it would kill the idea without any additional discussion. So my suggestion is that until the wireless charging sales people are willing to give actual numbers in standard units, that they be regarded as just plain liars. There is no way to make a problem go away just by refusing to talk about it. We need to see actual , reproducable, numbers to back up all those claims about it being so wonderful.
Simonts--This is one thought I had also. I have a good friend who has just had a pacemaker installed and several with hearing aids. It would be very desirable to find out what effects the wireless charging devices have, if any, on "hardware" such as pacemakers, hearing aids, TENS units, pumps, etc. etc. I am sure the manufacturers have thought of this and hopefully there are standards governing the use of these devices. One other thing, the receiving unit seems to be mounted under the rear of the car so, what resulting ground clearance are we talking about? Great post Charles.
I just bought a new Jeep Cherokee that has a wireless phone charger in the center console. I still think it a waste and question the people who want it. However I have received priority tasking from my wife to find her a Qi charging receiver for her Galaxie SIII phone. I guess 'those' people are closer to me than I thought.
I agree with you, Watashi. Yes, some people are very lazy. And yes, I don't want to drive on the same roads with them (have you ever noticed how many people recline their driver's seat WHILE they are driving?). Unfortuntely, though, they'll always be there.
I agree simonts this should be one of the major concerns, before launching the technology. There are definitely side effects of wireless charging that are mostly ignored in many applications. But as they are incorporating it in to automobiles, that means larger size which also means greater radiations. Thus, It would be totally meaningless to ignore its effects on health. I hope they make substantial amount of research in this area and adopt some preventive measures on it.
Tesla Motors’ $35,000, 200-mile electric car may not revolutionize the auto industry by itself, but it could serve as a starting point for a long, steady climb to a day when half of the world’s vehicles will be plug-ins.
