INTRODUCTION
Typically, simple battery chargers do not provide the
intelligence to charge different battery technologies or
batteries with the same technology but different voltages
and capacities. At best, this may leave the battery
improperly charged. At worst, it can pose a serious
safety hazard. A microcontroller can provide the intelligence
to overcome these problems.
In addition to intelligent control, the microcontroller can
provide a low-cost, flexible solution for charging batteries.
Complete battery charging applications may be
developed quickly using a microcontroller. Add to this
the serial communication capability of the microcontroller,
real-time data logging and monitoring is possible.
Simple battery chargers use all analog components to
accomplish their function. However, by using a microcontroller,
a battery charger can be made intelligent.

阿莫论坛20周年了!感谢大家的支持与爱护!!
如果天空是黑暗的,那就摸黑生存;
如果发出声音是危险的,那就保持沉默;
如果自觉无力发光,那就蜷伏于牆角。
但是,不要习惯了黑暗就为黑暗辩护;
也不要为自己的苟且而得意;
不要嘲讽那些比自己更勇敢的人。
我们可以卑微如尘土,但不可扭曲如蛆虫。
