Slideshow: Wireless Charging Comes to Automobiles

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.

If the government believes that they are right in mandating efficiency increases in those very small "wall-wart" devices then I certainly hope that the same sort of rules wind up being made to apply to the wireless charging systems, which are terribly inefficient. But it seems that the glamerous thing gets away with whatever it wishes to do.

And still there does not seem to be much discussion on the potential bad effects delivered by that energy radiated that does not make it into the targeted battery system.

Once again, truth is missing.

And if an individual is so very inconvenienced by plugging in to charge, then my evaluation is that probably they don't even deserve to drive any car.

AND here is another concern not previously discussed, which is that if charging commences whenever the vehicle would be parked it will only be a few hours before some much less honorable individuals establish some very expensive charging points, and rob the poor unsuspecting drivers with very high charging fees. And how will a driver know what they are being charged until the bill arrives. So there you have the ultimate fault of wireless charging systems. So those "dirty" fossile fuels will be replaced by the chance to be robbed every time one parks their vehicle. Not quite a fair trade, I don't believe. But definitely a potential consequence of what the unthinking believe to be a good idea.

This is where the technology needs to go. If charging is ubiquitously everywhere, electric cars will predominate for most transportation needs that are not continuous duration, long haul. People are just stuck in the paradigm that they have to go to a gas station to fill up their fuel. If every time they parked their car began to charge wirelessly, it would destroy the paradigm the dirty fossil fuels industry relies on to convince shallow thinkers that combustion engines are the best most cost effective technology. I find people in America still believe the price of a gallon of gas is what they pay at the pump; they never consider the costs hidden in the military being used to defend the fossil fuels industry, as well as that hidden in the dangerous environmental effects fossil fuel use is demonstrably having on the environment. As usual some fools are happy with the fossil fuels industry privatizing their profits and and socializing their costs.

e-007, the belief that there is no need to understand anything does not make me laugh, but rather feel like the clowns are running the asylum, or worse. It is a quite uncomfortable feeling that I am not respected at all for my engineering knowledge and talents, while some punk who dresses to the latest fad gets all of the aclaim, and a lot more income, which really offends me, by the way. 

Right now I am seeing problems brought on by others ignoring my requests to do things differently than they had in the past. I would like to tell them "I TOLD you so", but the problems are here and real and that would not do any good. Of course, I did not press the issue back then because after being told I didn't know what I was talking about so many times I developed an attitude that I would let them "put thier hands in the fire."

The old line seems to be true: "You can't fix stupid." What a pity.

Very True William K our schools today cater to the average idiot not to the average genius. Too easy is making a lot of people believe that knowing very little is ok. In reality it leads to poverty and many other things including one paying more than 10 dollars for a system that links the grid to your car??? I mean really a wire can do the job and a plug why bother with electronics that you don't understand how they work???? Tech like this makes me laugh most of the time.

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.

Efficiency Vs. Lazy

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.

But what about the efficiency? Still asking.

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.

Update:

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 will NOT bring this slideshow to her attention.

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.
