Contactless recharging for cars

As you know, the technology of wireless battery charging by electromagnetic induction has already gone into production and the corresponding microchips for portable electronics have already been manufactured. But what to do with car batteries? Indeed, in the automotive industry, the technology of charging "by air" is even more necessary than for electronics.

Probably, to solve this problem will be very difficult, because for the most efficient charging by the method of electromagnetic induction requires very close contact with a radiation source (no more than a few centimeters), so in the case of cars you have to come up with something unusual.

This task was attended by the world's largest car manufacturer - Japanese Toyota. She joined forces with the company WiTricity from Massachusetts (USA), which is engaged in research in this area.

WiTricity is developing a more advanced way of transmitting energy, which provides energy transfer over relatively long distances, even through walls to several receivers simultaneously. This is achieved through the use of the so-called resonator . Allegedly, this method is even more effective than electromagnetic induction.

The task is this: to develop technology for contactless charging of electric vehicles and hybrids by ordinary parking the car in a specially designated place where the radiation comes from. In this case, charging cars will become easier and more familiar than filling vehicles with liquid fuel, because special parking spaces with payment machines can be equipped, for example, near supermarkets, so the car will be charged while you are shopping.

Toyota is not the first major automaker to begin research in the field of wireless recharging. In January 2010, General Motors announced a technology partnership with Powermat, but there the goal was to make a wireless portable electronics recharging system inside the cabin, not the car itself.
