摘要

本文為「多功能獨立型光伏電池充放電控制器之研製」，使12V、24V、48V等不同電壓之蓄電池皆可使用於本控制器。目前市面上有關太陽能充放電控制器的相關產品，皆以一種電壓規格設計，12V、24V、48V等都各自獨立，不能共用，本文將其整合，讓以上三種電壓規格之蓄電池皆可使用本文設計之控制器，再加上改良式擾動觀察法之最大功率追蹤控制與混合定電壓定電流控制，使太陽能充電效率更為提升，配合殘電量估測，使控制器可以準確的進行蓄電池充放電之控制，最後透過LCD面板以及RS-232可讓使用者隨時監控目前太陽能板與旭電池的狀況，並可與電腦連線紀錄其相關數據。

The present study “the design of a multifunctional stand-alone photovoltaic chargedischarge controller” is to make sure that the various batteries with 12V、24V and 48Vcould be charged/recharged by the present controller. Nowadays, all the related solar-power charge/recharge controllers are based on one kind of voltage specification design (such as 12V chargedischarge controller, 24V chargedischarge controller, etc.). They are used independently and cannot be combined together.
This thesis describes the integrated design of 12V, 24V and 48V chargedischarge controller. Thus, these three kinds of voltage battery could be charged and discharged by one controller. Besides, the present controller can also improve the function of maximum power point tracking control and obtain higher efficient solar energy charge. To integrate with the remaining electric quantity estimation, the design of this study enables the battery charge/discharge control more accurately. Finally, by using the LCD and RS-232, this controller is able to record the related data by connecting the computer, thus it can monitor the solar cell and battery's condition anytime for the user.
