Cars will never replace horses -induction charging

**PhilipA** · 2nd January 2013, 01:44 PM

I recall that a couple of years ago when I suggested that this would be the next step for electric cars I was roundly thrashed by the cognescenti that it was "impossible "etc etc. Yetserday electric toothbrushes tomorrow cars.

New way to charge electric cars: Toyota

TOYOTA has started field trials with a wireless charging system that allows electric cars to replenish their batteries without needing a point of contact.

The system uses magnetic resonators buried in the road surface of a parking space.
This does away with the need to plug the car into electricity mains using a cable.
The wireless charging device is contained in a mat measuring about 50cm across. When the car is parked the mat is raised automatically and the AC power is delivered via the magnetic field created under the vehicle.
The first phase of testing starts in Toyota City in January.
Engineers hope to reproduce genuine everyday conditions.
Toyota says a typical Prius-sized model can be recharged in 90 minutes using the wireless induction system - the same amount of time needed for conventional cable charging.
One slight drawback is that drivers who do not position the car directly above the magnetic mat will find that charging takes slightly longer.
Toyota has not announced when the wireless charging technology will go into production.

Just what we need, someone will park their car at the wrong angle, park a non electric car or a fault will develop in the system and the induction mat will electrify the whole car.

Then we'll have to install automatic defibrilators next to every induction parking bay to rescue the people electrocuted by a faulty system.

At least with a plug in system, we know when we plug in the car.

Keep it quite, you may be have some marketing opportunities there

Next will be parking spots with induction charging for the electric scooters used by the white head brigade.

I think that efficiency is going to be an issue here. Inductive charging, even if the car is parked perfectly over the pad, wastes quite a lot of energy. Multiply that by the number of electric cars they want on the road, times having to charge your car on a daily basis, electric cars aren't going to be any greener than their petrol powered equivalents.

Sounds like technology looking for an application.

In cold countries they already have to plug the car in to stop the engine oil getting too thick. I am sure people can manage to park and plug without difficulty, most have been trained to plug a power cord in by the time they get their license.

Considering that Toyota has recalled the entire production run of Prius vehicles three or four times for serious faults and just paid out a billion or so on other recalls caused by electrical faults maybe they should workout how to make normal vehicles properly first. Pat

In this case is not plug in, is induction charging as was introduced bt Halo the Kiwi company that was sold to Qualcomm
You can read something about it HERE

Interesting...GM had an inductive system for charging electic cars back in the 90s... was called Magne Charge. Inductive charging was also used in some types of cardiac pacemakers for years before superdooper long life batteries came along

Point he's trying to make (I think) is why?? Other than the technical challenge? We can install inefficient, potentially unsafe induction chargers that have to be parked on within exact tolerances, or we can put a $20 high powered charge point on the back wall of the parking space that you can plug your car into when you park. Which would you choose?

Doesn't the Caboulture RSL Club already have one of them?

There seems to be a row of mobility scooters parked up at the front door.

Me being a pessimist again, now we'll have people lying prone in inductive charge bays to give their pacemaker a boost!
