【摘要】 本文设计了一种针对镍镉电池的智能恒流充电器,具有结构简单、充电快速的特点,采用恒流充电的方式,对电池进行充电,有电压检测功能,转换电路由MOSFET功率开关来控制电流大小的切换,实现充满后自动转为涓流充电且报警提醒,保护电池寿命。在电路中用AT89C2051单片机来实现控制作用,从软硬件两个方面来共同实现,且整个充电过程可由单片机控制的指示灯看到。更多还原

【Abstract】 This paper introduces a design of an intelligent constant-current charger for Nicd battery with simple structure and high efficiency.It works in the way of constant current charging with the detection function by voltage.Transforming circuit,MOSFET power switch is used to change the size of current.When the battery is filled,it’s turned into trickle charge automatically with the warning alarm in order to prolong the life span of battery.AT89C2051 single-chip microcomputer is used to control the whole circuit with the help of hardware and software.Besides,the whole process can be seen by indicator lights.更多还原
