基于磁耦合谐振的城市电动汽车动态无线供电技术研究

The proposal aims to solve the two major bottlenecks, battery problems and infrastructure issues, in the commercialization of electric vehicle, which is try to find a fundamental solution. Urban electric vehicle dynamic wireless power transmission system can ensure the real time power supply for electric vehicles, no matter they are in parking, waiting traffic light or running. The technology can not only extend or even unlimited extend the driving range, but also can significantly reduce the amount of battery used in vehicle. The amount of battery will reduce to a fraction of the original vehicle. There will be no charging stations and power plants on the ground, instead the power supply problems can be automatically solved by the underground power supply network. .Propose the urban electric vehicle dynamic wireless power transmission solution which are based on the magnetic resonance coupling, mainly include the following key issues: the establishment of high power density, simple structure, low cost coupling mechanism design method, the investigate of electric/magnetic circuit integration and reverse parameter optimization, the enhanced technology for weak coupled resonance, power transmission stability control strategy under multi-load condition, and dynamic impedance matching..Through the research of this project, the system design and analysis methods for low cost, high efficiency, high power density, high electromagnetic compatibility and fast response dynamic wireless power transmission system which are suitable for the urban electric vehicle can be established. Then it will promote the development of the electric vehicle industry in the future.
