摘　　要：近几年中国电子产品市场一直保持跨越式增长,其用电问题及电池使用寿命也成为制约电子产品发展的瓶颈之一。针对这一问题,该文设计了一种智能充电系统,其由单片机、继电器、电源、采样、显示、按键等模块构成。单片机通过采集电压、电流值以实现在液晶上显示充电电压及电流,通过库仑计法实现电池电量百分比的显示,通过控制继电器来控制充电时间段以实现峰谷电优化充电及过充保护。实践表明,该设计在节能减排方面具有较高的推广价值。In recent years,China’s electronic product market has maintained rapid growth.Its power consumption problem and battery life have also become one of the bottlenecks restricting the development of electronic products.Aiming at this problem,this paper designs an intelligent charging system,which consists of single-chip microcomputer,relay,power supply,sampling,display,button and other modules.The single-chip microcomputer collects voltage and current values to display the charging voltage and current on the LCD,displays the battery power percentage by coulomb counting method,and controls the charging time period by controlling relays to achieve peak-valley optimized charging and overcharge protection.Practical application shows that the design has high promotion value in energy saving and emission reduction.
