So how does it work?

Using this technology in cars simply requires a base unit on the ground, for example on a driveway or in a garage, and a receiver on the carCouncil powers on with plan to install more electric car charging points in North Lincolnshire.

The biggest problem could be parking accurately enough to charge efficiently, but Giler says WiTricity have tailored the system to drivers’ shortcomings.

“Most drivers are pretty good at stopping in the right place going forwards or backwards, not so good at left or right. Our system has a wide range so that doesn’t matter so much. I like to say ‘if you can park in the garage, you can do it.’”

How much will it cost?

Obviously, ripping up your garage floor and putting in a big charging unit would costUK EV Sales: Electric vehicles create buzz. Read more ... » quite a lotElectric Car Battery Prices on Track to Drop 70% by 2015, Says Energy Secretary. Read more ... », so WiTricity is suggesting a mat which can be plugged in and laid on the floor at a cost of around US$750.

Of course, the car will need to carry a receiver unit, but according to Giler, that should cost “no more than a normal optional extra like sat nav” and with a weight of just 2Frost & Sullivan: 351,900 Inductive Charging Units Top Be Sold Globally By 2020.

Fortunately, energy bills will not spiral with the use of the WiTricity system as it uses exactly the same amount of energy as charging from a plug.

How far is it from being ready?

At present, the greatest challenge for WiTricity to overcome is efficiency, as Giler explains: “To make it work the plug to battery efficiency must be greater than 90%. Most wireless phone chargersCheltenham Bikes installs electric car charging points at its Railway Station HQ. Read more ... » are around 85% efficient.

Read more ... » efficiency to get to the high nineties and between the magnets our technology is 98.5My future "next car" :Plug-In Hybrid Model(s) To Join Next Audi A4 Range.

The problem for WiTricity is the wiring, rather than the magnets. While only a negligible amount of energy is lost in the wireless stage, it loses efficiency in the hardware either side of the transfer.

That doesn’t seem to be too much of a worry for Giler, though. As WiTricity’s invention is being trialled by ToyotaUK EV Sales: Electric vehicles create buzz.
