微小功率智能充电器设计(论文13000字)
摘要：微小功率智能充电器是针对手机锂电池设计的充电系统。它能根据待充电池自身状态选择合适的充电模式同时进行实时充电信息显示，并在完成充电后进行报警。在本设计中，智能充电系统结合充电芯片完成智能充电的同时，通过电压检测模块结合模数转换器采集电池的充电电压，并以曲线图的形式实时显示。除此之外，还利用不同元器件特性设计了防过充保护电路和报警模块，实现对待充电池的保护。在系统中还特别增加了触摸屏模块，并设计了UI界面以改善用户体验。实验结果表明，该款充电器可以很好的实现电池的快充、满充、自动断电、充满提醒、充电数据实时显示等功能。

Micro power smart charger design
Abstract：The lithium battery intelligent charging device is designed for the mobile phone lithium battery, and selects the appropriate charging mode according to the state of the battery to be charged, and simultaneously displays the real-time charging information, and performs an alarm charging system after completing the charging or charging error. In this design, the intelligent charging system combines the charging chip to complete the intelligent charging, and the charging voltage of the battery is collected by the voltage detecting module combined with the analog-to-digital converter, and displayed in real time in the form of a graph. In addition, the anti-overcharge protection circuit and the alarm module are designed with different component characteristics to realize the protection of the rechargeable battery. A special touch screen module has been added to the system, and a UI interface has been designed to improve the user experience.The experimental results show that the charger can  realize the functions of fast charging, full charging, automatic power-off , full reminder, real-time display of charging information and so on.
