基于AVR单片机的智能充电系统设计与实现

Design and Realization of Intelligent Charger System Based on AVR MCU

为了能够给不同端电压、不同容量等级以及不同类型的蓄电池进行智能充电,设计了以AVR单片机为控制核心的蓄电池智能充电系统.系统通过对蓄电池充电电压、电流以及温度的实时检测,根据电池的类型、电压和容量等级调用相应的充电算法程序,实现对整个充电过程的智能精确控制.最后对12V/16AH的铅酸蓄电池进行了充电试验,试验结果表明,充电电流与电压曲线与理想曲线基本相符.

Intelligent charger system for battery based on AVR MCU was is designed, in order to charge intelligently different kinds of battery which has a series of voltage and capacity. During the process of charging battery, intelligent and precision controlling was implemented in the way that charger system carried out relative program for different type, voltage and capacity battery with detecting the voltage, current and temperature of battery. Last, experimentation was made for 12V/16AH acid battery, and the re- sults proved that the charger curve of voltage and current was basically consistent with ideal charger curve.
