April 5, Beijing time, United States Oak Ridge National Laboratory have developed a 20-kilowatt Wireless charging system, and efficiency can be pushed to 90%.
Wireless charging a smart phone may be helpful, but this charge is slow, and it will have a greater heat loss. Equipment for electric vehicles that use a large-capacity battery, the problem is more serious.
United States Oak Ridge National Laboratory presented with very high efficiency Wireless charging, power 20-kilowatt, efficiency is up to 90%, enough to provide within one or two hours and 60 miles (about 96 kilometers) range.
This is still just a proof of concept, is not ready for commercial preparation. Nevertheless, Oak Ridge National Laboratory also plans to develop a 50-kilowatt wireless charger, charging speed comparable to today's fastest plug-in charger. Reduced cost, will be able to achieve widespread popularity.
Oak Ridge National Laboratory believes that this automatic driverless car technology will become an important contributing factor. If the car can be in the absence of involvement of the charge, that can really achieve fully automated and driverless.
However, to achieve the driverless car Wireless charging, require special equipment. There are no vendors provide a solution, but there are still some late reformation of accessories can be used. Hello Kitty for Note 4
