Operation and Monitoring Technology of Mobile Wireless Charging for Electric Vehicles

Abstract

Facing the increasingly severe pressure on energy conservation and emission reduction, the world's auto industry has entered a period of comprehensive transportation energy transformation. Vigorously developing electric vehicles have become a clear direction for governments of the United States, China, and Europe to develop new energy vehicles. The charging problem is one of the important factors restricting the development and popularization of electric vehicles. Most electric vehicles use a contact-type wired charging method. This wired charging method has many inherent defects: plug-in is easy to produce sparks, easy to wear, difficult to maintain, and not flexible enough, which reduces the driving experience of electric vehicles to a certain extent. The wireless charging technology for electric vehicles developed in recent years provides new ideas for solving the above problems. Combined with the current status of domestic and foreign technology development and recent scientific research work, it has not comprehensively and in-depth considered road conditions and vehicle operating conditions adaptability, operational reliability, scalability, energy efficiency and other practical technical indicators. It is necessary to carry out in-depth research on engineering application technology to solve engineering and practical technical problems such as planning, design, construction, civil engineering, operation, and standardization. Electric vehicles are an important part of the smart grid, and large-scale electric vehicles can also be used as energy storage devices for the grid. The application of stationary and mobile wireless charging technologies can greatly improve the interaction between electric vehicle and grid. In order to increase the reliability and convenience of operation, there is an urgent need to develop an electric vehicle mobile wireless charging section operation and monitoring program, laying a technical foundation for the establishment and construction of the electric vehicle mobile wireless charging demonstration project.
