The scientific research community has been studying the effective method of allowing electric vehicles to drive on the roadside while charging, thereby overcoming the limitation of short cruising range for electric vehicles. Researchers at the Stanford University in the United States reported in a new issue of the British magazine Nature that their new results have taken this type of research a giant step forward. One of the study's authors, Professor Fan Yan of Stanford University, told Xinhua News Agency reporters that they use a simple method to achieve dynamic wireless power transmission. This progress has solved a major technical obstacle for wireless charging of electric vehicles in the future. Fan Hao said that there is a basic problem in the traditional wireless charging technology. That is, the energy transmission efficiency is directly related to the charging transmission distance. The optimal charging parameter depends on the charging transmission distance. If the charging distance changes due to the movement of the object to be charged, the parameters of the circuit required for charging must be readjusted manually, which increases the complexity of the circuit. In order to solve this problem, Fan et al. researchers improved the wireless charging technology researched and developed by MIT in 2007, so that the transmission system can automatically adjust to the transmission when the transmission distance changes continuously. The optimal state of energy required, the charging efficiency remains constant. According to reports, this wireless transmission system consists of two coils that are approximately 1 meter apart. One of the coils generates a magnetic field that influences the current of the other coil, thereby wirelessly transferring electrical energy from one coil to another. The traditional technique is to use a microwave source for the transmitting coil and manually adjust the microwave frequency when the transmission distance changes. In the experiment, the researchers removed the microwave source and replaced it with an ordinary voltage amplifier. When the researcher moved the receiver coil, one LED bulb on the coil continued to light up. This shows that the receiver achieves efficient charging when in motion. Fan Wei said that dynamic wireless charging can also be achieved through more complex parameter control. The latest research shows that a simple wireless dynamic energy efficient transmission can also be achieved. He said that the advancement of dynamic wireless charging technology will help to realize the idea that electric vehicles can continue to run without stopping charging. For example, the coil at the bottom of the car can receive power transmission from the underground coil of the highway, and the car can wirelessly charge on the highway. This technology can also be used for wireless charging of personal mobile devices such as mobile phones.
