【正文】 people begin to pay more attention to the use of solar energy. The paper designs a feasible solar energy charging controller and storage batteries are charged to meet the needs of lowpower users.This article focuses on the use of singlechip realization of solar charge control technology. 100watt solar panels to 12volt solar battery charge controller hardware system is detailed, including system hardware circuit design, the various parts of the circuit functions, working principles and models of selected electronic ponents. Hardware system is posed of four parts, which are DC regulated power supply circuit, A / D to achieve on the battery terminal voltage of the dynamic monitoring and conversion, AT89C51control and output switching circuit. And finish the entire solar charge controller circuit schematic design and production. PROTEUS simulation with circuit simulation software was acplished, and a corresponding circuit board was produced. However, due to time constraints, I failed to plete the kind of experimental test.In this paper, also the structure of the principle of solar cells, solar panels of the Volta metric characteristics of leadacid batteries monly used in the work of principle was detailed, and the basis of methods monly used on rechargeable batteries was introduced.Key words: Solar,Battery。但是由于時間關系，沒能完成實物的實驗測試。電池充電的太陽能控制器硬件系統(tǒng)，包括系統(tǒng)的硬件電路設計、各部分電路的功能、工作原理和電子元器件型號的選取。本文試圖設計一種切實可行的太陽能充電控制器，通過對蓄電池充電，滿足小功率的用戶需求。學 號 0809131089 畢 業(yè) 論 文（設計） 課 題 太陽能手機充電器的設計 學生姓名 李夢竹 系 別 電氣工程系 專業(yè)班級 08 通信工程 指導教師 吳慧 二 O 一 二年 六月目錄插圖清單 ..........................................................................................................................................I摘 要 .........................................................................................................................................IIAbstract......................................................................................................................................III引 言 ..................................................................................................................................... 1 第一章 緒論 ............................................................................................................................. 2 設計目的 ........................................................................................................................... 2 設計思路和分析 ............................................................................................................... 2 硅太陽能電池與參數(shù) ....................................................................................................... 2 系統(tǒng)總體框圖設計 ............................................................................................................ 2第二章 太陽能充電器硬件電路設計 ....................................................................................... 5 太陽能電池板部分 ........................................................................................................ 5 蓄電池部分 ...................................................................................................................... 7 電池的定義 ................................................................................................................ 7 充放電特性 ................................................................................................................ 8 蓄電池作為電源模塊的設計 ..................................................................................... 9 單片機部分 ..................................................................................................................... 10 電壓電流的 A/D 采集 ..................................................................................................... 11 BUCK 斬波電路 ............................................................................................................. 14 數(shù)碼管顯示電路 ............................................................................................................. 15 第三章 軟件設計 ................................................................................................................... 17 系統(tǒng)的總體程序設計框架 ............................................................................................. 17 數(shù)碼管顯示子程序 ......................................................................................................... 18 數(shù)據采集及模數(shù)轉換程序 ............................................................................................. 19 充電子程序的設計 ......................................................................................................... 19 電源子程序的設計 ......................................................................................................... 20 結 論 ................................................................................................................................... 22 參考文獻 ......................................................................................................................
