Abstract

The recent development in simulation speed and capacity of magnetic field, and the power electronics, the field of wireless power transfer has been developed significantly. In the future transport area, electric vehicles are considered as replacement of oil-powered internal combustion engine driven vehicles, especially for the CO2 reduction and alternative energy perspective. However, electric vehicle requires several key issues resolved in view of the heavy weight, bulky volume, and limited driving distance. In this paper, the innovative on-road dynamic wireless charging technology for electric vehicle, called OLEV, is introduced. The electric vehicle charging technology can be classified as conductive or wireless, stationary or dynamic, and slow or fast. The fast charging in the range of 100 kW of power capacity and wireless dynamic charging concept are described. Also the design concept, system architecture and development process of optimizing the magnetic flux field for the higher power transfer efficiency are described in this paper. The dynamic charging technology is also compared with the stationary conductive charging for electric vehicles, in view of its development concept and status, and practical feasibility of the innovative technology.

采用无线电力传输技术的电动汽车道路动态充电系统

近年来，随着磁场仿真速度和容量的不断提高，电力电子学、无线电力传输领域得到了长足的发展。在未来的交通领域，电动汽车被认为是燃油内燃机驱动汽车的替代品，特别是从减少二氧化碳排放和替代能源的角度来看。然而，由于电动汽车的重量大、体积大、行驶距离有限，需要解决几个关键问题。本文介绍了一种新型的电动汽车道路动态无线充电技术——OLEV。电动汽车充电技术可分为导电充电与无线充电、静止充电与动态充电、慢速充电与快速充电。介绍了100kw功率范围内的快速充电和无线动态充电的概念。介绍了为提高功率传输效率而优化磁场的设计思想、系统结构和开发过程。针对电动汽车动态充电技术的发展理念和现状，以及创新技术的现实可行性，将动态充电技术与固定式导电充电技术进行了比较。
