 摘要
 
 本文介绍了锂电池和镍氢电池的不同特性，针对目前市场上多数充电器是通过硬件限制上限电压来防止过充电和放电保护的情况，研究开发一种可以通过软件实现充电控制的智能镍氢/锂电池充电器。通过高级图像编程语言(LabVIEW)对电池充电的硬件控制仿真实现对电池充电的软件控制。其中着重写到了硬件系统的结构及功能，包括充电模块，过充保护电路，温度检测电路，放电电路。充电功能主要为一个功率放大电路，采用了TDA2009实现。过充保护通过对电池充电状态实时的电压电流检测，使用软件控制进行实现。放电电路为一个纯负载电路，通过三级管TIP122实现放电保护。通过上述模块设计了一套基于LabVIEW语言的智能可充电锂电池和镍氢电池的充电装置控制软件和相应的硬件驱动电路，通过数据采集卡对接，实现对上述电池的智能充电，提高效率并延长其使用寿命。

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.
