多功能充电器电路分析及其编程控制的实现

The Circuit Analysis of Various Functional Charger and the Realization of Programming Control

多功能充电器是一种高性能低价位的可对镍镉、镍氢及锂离子电池充电的电路设备.充电器采用单片机GMS97C2051作编程控制器,其内部的比较器用作电池高温度检测,用一片LM324和一支TL431以及若干分立元件构成恒压———恒流电路、电压检测电路、基准电压源电路.

The charger of various functions which has high performance and low price is a kind of circuit equipment that can charge the batteries of Ni -Cd ,Ni- H and Li. The charger adopts GMS97C2051 as the programming controller whose inner comparable apparatus works as cell detection with high temperature,constant voltage and current, circuit of voltage detection and basic circuit of voltage resource are composed by an LM324, a TIA31 and several branch components.
