The electric car is now a hot market, but this problem restricting the rapid spread of this new energy vehicles, charging inconvenient. Japanese researchers have invented a new method, the electric vehicle charging in the process of moving, motorists do not have to always thinking about looking for a charging station.
Electricity passing through the incoming car tire on the road
Toyohashi University of Technology in Japan showcase wireless charging technology trade show held in Yokohama.
Researchers public roads in Japan with the same concrete bricks in the booth on both sides of the white base, pedestal built generator. Each placed a full-size tire on both sides of the brick, both connected to the wire, the wire and the middle is still attached to a light bulb.
Concrete bricks 10 cm thick. The researchers say that the the generators power of 50-60 watts of electricity through the bricks incoming car tires. Lamp shiny is tire Charged proof.
British "Daily Mail quoted the words of Professor research is responsible for the NPC level Hyo reported, even concrete thick and then doubled, it will not affect the electrical conduction. In actual use, generator power must achieve the presentation model 100 times before charging the electric vehicle traveling. However, this is technically not a problem.
"Road charging device become very popular
Ohira Hyo said transmission of power through the concrete floor to the efficiency of the vehicle can reach 80% to 90% under ideal conditions, can even be higher. However, last year, the experimental results show that, under normal circumstances, about 20% power loss in the transmission process, researchers will further study to address the problem of power loss.
Researchers to this through road charging device name "forever" (EVER), electric vehicles charged on the road, "the English acronym. They believe that cost less than the construction of road charging "electric car charging stations.
The Ohira Hyo obtain official permission and the public is widely accepted that the construction of road charging "device can quickly popularity, because it technically does not exist obstacles.
Electric vehicles in the global concern
Currently, many countries and regions and vigorously promote electric vehicles, and offers a range of incentives for electric vehicle driving. Norwegian government enacted regulations that electric cars can use bus lanes from the pain of the traffic jam, do not have to pay the congestion charge, but also free parking in the city center parking.
However, limited travel distance is still the biggest factor limiting the development of electric vehicles. Israel`s concept of a business of battery replacement and service electric car network.
More researchers put the focus on the innovative charging method. Qualcomm said last year it plans to install inductive energy transmission system "during the Olympic Games in 2012 in the streets of London" trial version for electric vehicle charging. Japan`s Toyota Motor Company has also recommended to install a metal plate system to charge on the ground.
