设计了一种直流电能充电器，该充电器可将直流电源的能量传递到3.6 V以上的可充电电池中。系统根据输入电压不同采用MC34063和HT7750来构建供电电路给电池充电，经过89C51单片机控制AD0832来检测电源输出电压的大小，从而判断是否对电池进行充电，并且检测时间的长短可以根据用户的需要进行设定，并通过数码管显示出来。为了提高单片机的工作效率，对单片机处于休眠和工作两种状态进行断续的检测。

A direct current charger is designed,which can transfer the energy of direct current power source to rechargeable battery above 3.6V. According to entering voltage,the system adopts MC34063 and HT7750 to structure the electricity supplying circuit to charge battery. The AD0832 controlled by 89C51 single chip is used to check the output voltage of power source,so as to judge whether to charge up the battery or not. The detecting time can be set according to demands of users,and displayed by the nixie tube. To improve the work efficiency of the single chip,its two modes of work and sleep are detected spasmodically.
