摘 要

就目前来看，电动汽车（EV）的充电问题将日益成为人们关注的重点，比如说将电动汽车连接到电力系统的基础设施（充电桩），所以车辆的使用将通过频繁的充电来提供动力，这与电动火车的情况相同。同时，在考虑到提高电动汽车的效率方面时，基于磁共振的无线电力传输一直是一个非常重要的技术。为了磁耦合谐振线圈组导轨传输能量的功率达到最大和效率达到最优，我们可以采用一些建模方法来分析整个线圈系统的传输过程，比如说利用等效线路模型和阻抗归算的思路，建立一种模型来分析能量传递，然后在此基础上，研究在不同线圈尺寸条件或者线圈之间的相对位置改变时磁耦合线圈传输能量的功率和效率。同时，也会分析这两个线圈以及这两个线圈之间的各种影响因子参数等，比如在不同的位置上线圈传输能量的特性，和他们的参数计算和能量传输的高效优化。

因此，本文重点会研究在电动汽车的无线充电过程中，当用磁耦合谐振式无线电能传输系统理论时，整个能量的传输过程。在绪论中展示了通过查阅资料和调研，发现目前研究的内容主要是通过一些设计上的改进来改善无线电能传输的优化，但是在偏移方面的研究不够系统，因此本文将系统完整地分析水平偏移（横向偏移和纵向偏移）对能量传输的影响，同时也会考虑到其他影响因子对传输系统造成的影响；第二章所做的主要工作是理论分析和建立模型，介绍无线充电系统的大体构成(发射线圈模块和接收线圈模块)，分析能量传输过程中能量的传递稳定性和效率，并且进一步计算得出了电能传输系统的输入功率、输出功率和整个系统的传输效率的函数表达式，基本完成理论分析；第三章中重点分析了不同的影响因子对电动汽车无线充电的影响，比如说一些比较固定的因子：系统的工作频率和车身的高度；又比如说一些比较实际的因子，横向偏移距离和纵向偏移距离；后来又从无线充电发射线圈的设计角度出发，分别分析了线圈的尺寸对电能传输造成的影响；最后，将水平偏移距离、等效负载大小和发射线圈的长度等影响因子结合起来分析；第四章是以第三章的仿真为基础提出了两个关于电动汽车无线充电的充电方案（以传输功率最大和以传输效率最高为目标），其中一个是通过设计发射线圈的尺寸来提高电能传输的效率和输出功率；另一个是通过提出电动汽车的推荐运行路线。

Design and optimization of wireless mobile power supply rail for electric vehicle

Abstract

For now, the electric vehicle (EV) charging problems will increasingly become the focus of attention, such as electric QiCheLian received power system infrastructure (charge), so the use of vehicles will through frequent charging to provide power, this is the case with electric train. At the same time, considering to improve the efficiency of electric cars, wireless power transmission based on magnetic resonance imaging (mri) has been a very important technology. To magnetic coupling resonant coil set the maximum power and efficiency of rail transport energy to achieve the optimal, we can use some modeling method to analyze the transmission process of the whole coil system, such as using the equivalent circuit model and the thinking of impedance reduction, establish a model to analyze the energy transfer, and then on this basis, the research on the relative position between the different size of coil or coil when changing magnetic coupling coil transmission of power and energy efficiency. At the same time, it will analyze the two coils and the various impact factors between the two coil parameters, such as in the position of different coil characteristics of transmission energy, and their parameters are calculated and the energy transmission efficiency optimization. Therefore, this paper will study in the process of wireless charging of electric cars, when using magnetic coupling resonant radio can transmit system theory, the energy transmission process. Shows through access to information and research in the introduction, found that the content of the current research mainly through some improvement on the design to improve the optimization of radio can transmit, but not enough in the migration of system, so the system completely, this paper analyses the horizontal offset (horizontal and vertical displacement) effect on the energy transmission, as well as considering the other influence factors on the impact of the transmission system; The second chapter, the main work done is theoretical analysis and model, composition of general introduction of wireless charging system (transmitter module and receiver module), analysis of stability and efficiency of energy transmission in the process of energy transfer, and calculated further power transmission system of the input power, output power and the transmission efficiency of the whole system's function expression, basically complete theoretical analysis; In the third chapter mainly analyzes the influence of different factors on the influence of the electric vehicle charging, some relatively fixed factors such as: the work frequency of the system and body height h f; For example some practical factors, transverse offset distance and ; vertical migration distance. Then from the Angle of the design of the wireless charging transmitter coil, respectively analyzes the impact of the size of the coil to electricity transmission; Finally, the horizontal offset distance, and the size of the equivalent load and the length of the transmitter coil combined impact factor analysis; The fourth chapter is based on the simulation for the third chapter puts forward two about electric vehicle charging scheme of wireless charging (in power transmission and a maximum transmission efficiency is highest for goals), one of which is through the design of a transmitter coil size to improve the efficiency of power transmission and power output; Another is by electric cars recommend running routes are put forward.
