Stanford, - In the United States, currently there are 5500 new battery charging station and will be a five-fold by the end of this year. Most filling stations are now also considered less practical for owners of electric cars. Even where fast charging with a DC current is still very step. 80-100 percent battery charging time takes at least half an hour. For those who travel a lot with my family, this condition's just not practical.
the electric car's biggest problem so far is very limited distance. Once the battery is only able to travel the farthest distance of 160 km. Another problem, the charging time is also longer than the filling of gasoline, diesel or gas. In addition, the infrastructure is still a step or filling station.
Still Simulation
In the simulation, is shown, the system consists of a series of electrical coils embedded in the filler in the asphalt road surface. Well, here's a charging coil car for speeding on it.
Richard Sassooon, Managing Director of the Stanford Global Climate and Energy Project (GCEP) to the Stanford Report explains, "a very interesting aspect of the concept inil, you could drive a car with no mileage limit and do not need to recharge. Have enough energy in the battery at the end of the trip, after which it can go back. "
Further, the magnetic system is not only helpful road mileage, can also solve the problem virtually. If one day the technology is implemented on the interstate, and most of the toll road, will make an electric car can travel further to trap more smoothly than gasoline cars.
Currently, the Stanford research team collaborated with the engineering department to find out the complexity and other problems in the design of roads and installation of this coil. In addition, has also been confirmed, the magnetic system is safe to the surrounding environment and it will not emerge radiation on humans or electromagnetic interference that can interfere with electronic equipment in cars.
10 kW
Actually wireless electric car charging system has been initiated there's even a lot of use. But it must be done at a place or the system only allows the owner does not have to plug the car plugs into a home or car depots.
The latest version developed by Stanford University is a wireless charging when it is in motion. It is also not new. In South Korea the concept have been tried. Nevertheless Stanford University researchers believe they have developed a wireless charging will be the key to the future of electric cars.
The experts at Stanford mengatakankan, charging system they developed to work with greater power. Resonance system that was developed to transmit 10 kW of electric power from the source and the receiver coil on the car's path.
It is said that the coil power source mounted on a position 90 degree bends in the metal plate, can move 10 kW power to the coil in the same vehicle within a distance of 2 meters. Efficiencies are also claimed 97 percent, far higher than any other wireless charging system that has been developed at this time. In fact, if the design is beyond repair, Stanford charging efficiency is more efficient.
The experts from major universities are currently doing on the computer simulation. The researchers have patented a system and plan further tests in the laboratory and on the road (actual conditions).
