At present, the popularization of electric vehicles there are obstacles, due to limited mileage, the public worried about charging electric vehicles can not be as fuel-efficient cars as fuel, after all, charging stations are not as common as gas stations. In order to solve the difficult problem of charging electric vehicles, EU researchers recently developed a wireless charging method for electric vehicles, hoping to make it easier to charge electric vehicles. August 28, the EU released the latest research progress.
Like WiFi to charge multiple electric vehicles
In fact, wireless charging technology has already begun to use in many fields, such as electric toothbrushes, remote controls, and cell phone wireless charging. Currently charging electric vehicles have to find the charging pile, then connect the cable charging, and wireless charging will be more convenient. Figuratively speaking, the charging method of charging piles and other wired charging is the same as that of a wired router. A network cable can only guarantee one computer network, and wireless charging is like WiFi which can provide network signals to multiple terminals at the same time. Using a wireless charging method, a charging station in a parking lot can charge a plurality of electric vehicles within a certain range.
The new wireless charging station developed by the EU also exchanges charging data with the car, including user codes, supplier codes, charging durations, and electricity meters. This information exchange process is controlled by a tablet placed in the car, thus simplifying direct communication between the driver and the charging station. The project's researchers said they are also developing a new application that prompts for the location of the charging station near the driver and ensures communication between the charging station and the vehicle.
In fact, the major manufacturers have already launched a support for wireless charging of electric vehicles. As early as 2013, Nissan chose its best-selling pure electric car, the Lefeng, as its model to promote wireless charging technology. In July 2014, Mercedes-Benz and BMW jointly announced their intention to jointly develop wireless charging technology for electric vehicles. Mercedes-Benz will be based on the new S-class test, while BMW plans to take the lead in the i8 body. Audi at the 2015CES show, showcasing Audi's latest wireless charging equipment, which automatically lift the power supply coil wireless charging technology, enough to cope with the higher chassis SUV.
Under the road buried in the grid, while the edge charge
Of course, the wireless charging technology for electric vehicles is not without drawbacks, such as wireless charging is usually slower than the cable charging half a beat, electric car mileage has always been limited, if the charging speed then slow down, no doubt affect its use . In order to solve this problem, EU researchers are also developing wireless charging technology in the traveling state of vehicles, hoping to significantly increase the mileage of electric vehicles and reduce the size of vehicle energy storage systems. Researchers believe that if there is a planned area along the road with induction panels to charge electric vehicles on the move, it is expected to extend the mileage of electric vehicles.
This way of using the surface of the road for wireless charging of electric vehicles is likely to be the future direction of development, compared to charging facilities and other ground facilities, it does not need to take up space on the ground, and electric cars do not need to stop charging to save time. In the driving process, the electric car does not reduce the anti-increase, it is really a cool thing.
In fact, the concept of "wireless charging for driving electric vehicles" has been proposed and tested before the EU. In fact, as early as 2012, Volvo started a project called "Power Grid Road System" and in Sweden H? Llered's test center built a test road about 400 meters long. The road is internally paved with cables. When the test truck passes the road, the vehicle automatically opens with the cable and a 750V DC will charge the vehicle.
The electric car wireless charging has entered the daily life of Korean people. In 2013, Gumi City, South Korea, paved a 12-kilometer wireless charging section. Pure electric buses can be charged while driving while driving on the road.
In August of this year, the British highways company and the British Transport Minister Andrew ç¡ ç¡ hang traces of debris 岸 岸 shore knock 缌 渌 渌 Ting Benjamin 醯 Nephew 樵 㜠㜠Song 诮 衲 Hui 硇 ┦ baking èš© trace é¦ trace é¦ cloud è°–? 8 months. This system connects the power line to the coil under the road surface and transmits the power to the receiver coil in the car through the air. Electric vehicles or hybrids equipped with the appropriate equipment need only be able to operate on this type of surface to charge the battery.
The EU states that from October 2014 to October 2015, the team tested the new charging station in the French city of Douai in northern France and will evaluate the efficiency and feasibility of wireless charging at the end of the trial, as well as its impact on electric vehicles User benefits and impact on the grid.
