摘要

本論文主旨在研製人機介面監控太陽能對鉛酸電池充電系統，並探討鉛酸電池之充電速度及特性。由於太陽能系統輸出電源受環境影響改變，且須防止鉛酸電池過充現象，所以必須設計適當充電系統及人機介面來監控其充電電壓及電流。
本實驗以 LabVIEW來處理運算，搭配資料擷取卡(DAQ)來擷取及輸出訊號，透過專案項目來顯示可用的I/O通道與執行系統。經由人機介面隨時觀看充電狀態，根據鉛酸電池溫度、端電壓及充電電流來調節責任週期，藉此控制直流對直流升降壓轉換器輸出電源，進而達成保護電池的目的。

This thesis presented a Human Machine Interface (HMI) of lead-acid battery charger for photovoltaic power system. Because the solar energy power was affected by environment and we had to prevent an overcharge of lead-acid battery, we had to design a charging system including HMI to monitor the charging current and charging voltage of lead-acid battery.
In this thesis, we designed the program graphically by using LabVIEW software. The software is combined with Data Acquisition (DAQ) which can present available I/O channels and operate the project items.
By using HMI, we can monitor the state of charging at all time. The duty-cycle is determined by the lead-acid battery temperature, charging current and terminal potential. The protection of lead-acid battery is reached by controlling the DC-DC Buck/Boost converter.
