毕业设计说明书(论文)中文摘要
随着当今社会科学技术的发展,二次电源的市场迅速拓展。而锂离子电池以其高效、无污染、噪声小等优点成为电动汽车、便携设备等行业的一个重要研究领域。而锂离子电池的使用寿命和容量受充电电路的影响较大,故一个性能优异的充电器显得尤为重要。
本文主要介绍了锂离子电池的工作原理、应用和发展以及几种充电原理和方法。运用一种电池模型,搭建了恒流、恒压、恒流-恒压三种充电电路。通过Multisim软件进行了几种充电电路的仿真研究,并通过示波器观察电流、电压变化曲线,并与理论曲线相比较。这样更加透彻的了解了锂电池的充电过程,直观地反映了各种充电方法的优缺点,为更加优异的充电方法提供了思路。
关键词锂电池恒流/恒压充电器 Multisim

Title Study of constant voltage / constant current charging technology for battery
Abstract
In today's society with the development of science and technology, the market of secondary power expands rapidly. The lithium-ion battery e an important research area of the electric car, portable equipment and other industries due to its advantages of high efficiency, no pollution, little noise. And the service life of the lithium-ion battery and capacity are greatly influenced by the charging circuit,so a excellent charger is of great importance.
This paper mainly introduces the working principle, application and development of the lithium ion battery as well as the charging principle and set up three models of charging circuit,constant current constant voltage and constant current-constant voltage included,and have a research of the charging circuits with the help of the current, voltage curve with the theoretical curve,we can have a thoroughly understanding of the charging process of the lithium ion battery and see the advantages and disadvantages of various charging provides a way for better charging methods.
Keywords The lithium-ion battery Constant current-constant voltage Charger Multisim
