In the big picture, consider the power losses (about 5%) from the infrastructure needed to deliver the power to those inductive charging coils.

Electric taxis will charge up wirelessly as they wait on the rank as part of a £3.4 million trial, ministers announced today.
Transport Secretary Grant Shapps said the new technology could eventually be used by public drivers of electric cars.
Ten taxis in Nottingham will be fitted with the hardware later this year.
When they are parked over pads installed in the ground, their batteries will charge automatically.
The system recognizes the vehicle and bills the driver for the power.
The technology removes the need for cables and fixed charging points. …

I had a boss that put 40,000 miles a year on his car commuting a ridiculous distance.
That would make this a 2.5 year guaranty.
Sounds like you got a good deal..and played a lot of golf :)
Or about a one-year warranty on his car.
Yeah that’s crazy.
” Uh, where does the electricity come from? “
From Obama’s, err, St.Greta’s stash.
Thank you! It was the best 7 years of my 79+ years life on earth, playing golf full time at the beautiful Royal Oaks country club golf course in Vancouver, WA. Played with seniors group with $6 fee in the pot and it was team versus team competition and the best winning team of the day got all the money in the pot that day. Then I did not like when the club decided to remodel the club house (which was nice already) and the monthly fee jacked up by $75. So switched to Orchard Hill golf club in nearby town which was cheaper, but the golf course was of course not as nice. But still great to play unlimited golf for a fixed monthly fee.
Wow man it sounds like a Lot of times of a lot of fun.
Cherished memories I’m sure.
It’s great you found something you liked so much.
Not always so easy to do for some.
In the big picture, consider the power losses (about 5%) from the infrastructure needed to deliver the power to those inductive charging coils.
I read that in Germany, private companies have set up charging stations and are losing money hand over fist as few as using those stations. According to the article, one outfit is charging 79c for each kilowatt hour, so a 100 kw car will be paying 80 Euro for a "fill up".
I'm with you in wondering what those stations here in the States charge - it's something you never read about.
Anybody have the experience?
I should have been clearing. What I wanted to know was how fast these contactless charging stations can charge a vehicle?
“I wonder about the power loss in those inductive coils and the battery they charge. Such coils are basically the primary windings of a transformer. The secondary is on board the train producing AC to the Power Electronics Unit. The power losses of a transformer Then consider the power loss (20%) with the Power Electronics Unit which converts the AC to the DC battery charging voltage along with the cooling fans and other parasitic loads. Then consider the power losses from charging the battery and its discharge losses.

FAKE NEWS
You are obviously lacking the Big picture, the small picture and some facts.
“I’m with you in wondering what those stations here in the States charge - it’s something you never read about. “
Tesla charges 28 cents per kWh. At home about half that.
Free if you visit your MIL.

You had the answer in #8

3.3kW, 6.6kW or 20kW are not rates. 20kw per hour or per minute or per day would be rates. 20kw is a total. Things like Miles per hour are rates, miles are totals.

I suggest you break out a book on electricity.
I also add the power losses from the individual to the government. They are using transportation to indoctrinate the people. I am sure that is the bigger picture.
Whatever. Your previous post was a bunch of bs.
This statement fragment I think threw you off: “The power losses of a transformer” I meant to say The power losses of a transformer, adds one more loss in the system. If you consider all the parts of the system, as illustrated by the schematic, you will understand how it is one that wastes lots of energy to make it work.
Nothing threw me off. What is off is your numbers.
“you will understand how it is one that wastes lots of energy to make it work.”
Would you believe a demonstrati8n Model is delivering 120 kw wirelessly at 97% efficiency!
Their goal is to deliver 400 kw!
