 摘要
 
 本文介紹了鋰電池和鎳氫電池的不同特性，針對目前市場上多數充電器是通過硬件限制上限電壓來防止過充電和放電保護的情況，研究開發一種可以通過軟件實現充電控制的智能鎳氫/鋰電池充電器。通過高級圖像編程語言(LabVIEW)對電池充電的硬件控制仿真實現對電池充電的軟件控制。其中著重寫到了硬件系統的結構及功能，包括充電模塊，過充保護電路，溫度檢測電路，放電電路。充電功能主要為一個功率放大電路，采用了TDA2009實現。過充保護通過對電池充電狀態實時的電壓電流檢測，使用軟件控制進行實現。放電電路為一個純負載電路，通過三級管TIP122實現放電保護。通過上述模塊設計了一套基于LabVIEW語言的智能可充電鋰電池和鎳氫電池的充電裝置控制軟件和相應的硬件驅動電路，通過數據采集卡對接，實現對上述電池的智能充電，提高效率并延長其使用壽命。

Abstract

 This article introduces the different character of the lithium battery and the NI-MH battery,against the current market,most of chargers is through the upper limit of voltage that the limit of hardware to prevent the circumstances of the overcharge and overdischarge.About this,to develop a kind of intelligent charger which can control by software.Through the High-level image programming language LabVIEW to imitate the hardware control system of battery charger,this is the software control of the charge.In this article,we put emphasis on the structure and functions of hardware system,include the charging of modules,testing, the temperature with the protection circuit or circuit discharge.On the main function for a large circuit, power has been sufficient protection tda2009. the battery through the charging of the current state of the real-time use of software to detect, to materialize. discharge control circuit to a pure load or discharge tube tip122 achieved through three levels of protection. by the design a set of modules based on labview language of lithium battery and NI-MH rechargeable battery charging devices control software and hardware driven circuit through the data collected from the docking,For the realization of the intelligent charging, enhance efficiency and extend their lifespan.
