【摘要】：随着全球环境的恶化,一次能源的日益缺乏,绿色能源中的电能成为其中的佼佼者,而电动汽车更是其在交通领域应用的翘楚。电动汽车的动力来源于电池,受当前动力电池技术水平的制约,电池的体积问题、环保问题、使用寿命问题和单次充电时间过长问题成为了限制电动车发展的主要问题和推广的瓶颈。电动汽车充电的主要方式有:接触式和非接触式两种,接触式的充电方式现在已经在电动车上应用广泛,但这种方式存在诸多问题,如当接触式充电使用快速充电模式时,其充电电流非常的大,会直接对局域电网产生影响,并对整个电网的稳定性产生隐患,接触式充电插接操作繁琐且费时费力十分不方便,当线材老化时会带来一系列的安全问题。相对于接触式充电,非接触式充电电能通过埋在路面下的发射装置以无线的方式传送给接收装置,从而使电动车少搭载甚至无需搭载储能电池组、延长续航里程、提高电能供给的便捷性和安全性。本文首先对磁共振式无线传能的原理从数学和电路两个角度进行了阐述。对比四种常用无线传能拓扑结构,确定了系统选用双串联补偿拓扑结构。对系统从数学和电路角度,建立了控制算法模型,为实际系统设计提供指导。本文研究了基于磁共振技术的非接触式充电系统的控制方法。采用PID控制器实现电动汽车的闭环充电,提高了传输的安全可靠性,并对系统为电动汽车进行稳定三段式充电的方案进行详细研究。在实际的方案实施中,本文选用32位处理器作为主控器,通过蓝牙2.0模块进行通讯,根据接收端发来的数据对充.电的发射端进行实时的调节,从而实现软件的闭环设计,通过硬件锁相环技术完成对频率的跟踪,实现发射端的闭环调节,最终完成软硬件设计。
[Abstract]:With the deterioration of the global environment and the increasingly lack of primary energy, the electric energy in green energy has become one of the best among them, and the electric vehicle is the leading application in the field of transportation. The electric vehicle's power comes from the battery, restricted by the current power battery technology level, the battery volume question, the environmental protection question, The problem of service life and the long time of single charge become the main problem and bottleneck in the development of electric vehicle. There are two main ways of electric vehicle charging: contact charging and non-contact charging. Contact charging has been widely used in electric vehicles, but there are many problems in this way, such as when contact charging uses rapid charging mode. The charging current is very large, which will directly affect the local power network and the stability of the whole power network. The contact charging and plugging operation is cumbersome and time-consuming and very inconvenient. A series of safety problems arise when the wire is aging. Rather than contact-charging, contactless charging electricity is wirelessly transmitted to the receiver via a buried emitter, allowing an electric vehicle to carry fewer or no energy storage batteries and extend its range. Improve the convenience and safety of power supply. In this paper, the principle of magnetic resonance wireless energy transmission is described from the aspects of mathematics and circuit. By comparing four kinds of wireless energy transmission topologies, the double series compensation topology is selected. The control algorithm model of the system is established from the point of view of mathematics and circuit, which provides guidance for the practical system design. The control method of non-contact charging system based on magnetic resonance technology is studied in this paper. The closed-loop charging of electric vehicle is realized by using PID controller, which improves the safety and reliability of transmission. The scheme of stable three-stage charging for electric vehicle is studied in detail. In the actual implementation of the scheme, the 32-bit processor is chosen as the main controller, which communicates through Bluetooth 2.0 module and is charged according to the data sent from the receiver. The electric transmitter adjusts in real time so as to realize the closed-loop design of the software. The frequency is tracked by the hardware phase-locked loop technology and the closed-loop regulation of the transmitter is realized. Finally the software and hardware are designed.
