The electric car has not been too down to earth because of inadequate infrastructure. However, efforts to facilitate the promotion of electric cars, such as recharging electric car batteries without wireless. Of the problem, the developed charging technology that will wirelessly, charging no longer have to plug the cable outlet with long dangling. Simply park your car on battery power then automatically be filled.
This technology is called resonance wireless. WiTricity using highly coupled magnetic resonance. Battery charger in direct contact with sources of electricity in the home / office. Charger is equipped with a magnetic resonator that generates a magnetic near field. In the car battery installed receivers wave. Electrical energy delivered via magnetic waves emitted near field.
In this way electrical energy can travel a certain distance without wires, also penetrate obstructions like walls. Also can send electricity to a number of tools at once. Electrical energy can only be accepted equipment that has been set only accept certain wave frequency. If not to set any frequency, can not accept.
With this technology, electric cars can be recharged simply by parking the car near a special tool. This tool will send electrical energy to the battery without a cable car. There is no direct contact with the car.
Previous WiTricity already developed this technology for charging cell phones, laptops, TVs and it took Toyota to develop this technology in order to refill the car. If successful this will give a big advantage because the future of electric cars is predicted to be more dominant.
