摘要

太阳能充电器设计的来源是将太阳能转换成电能，主要解决的技术问题是如何将太阳能转换成能够充电的电能。太阳能作为一种可再生能源它具有取之不尽、用之不竭和清洁安全等特点，因此有着广阔的应用前景，光伏发电技术也越来越受到人们的关注，随着光伏组件价格的不断降低和光伏技术的发展，太阳能光伏发电系统将逐渐由现在的补充能源向替代能源过渡。

太阳能充电器是由单片机最小系统、太阳能充电电路、ADC0832转换模块、太阳能充电电池、液晶显示模块和电源模块组成。太阳能充电系统是太阳能充电板在阳光的照耀下产生电荷，存储太阳能电池板的电荷，经过稳压芯片稳压后给TP4056芯片提供电源和充电电池充电。充电时，充电指示灯点亮，当充电完成后，充电指示灯熄灭。利用ADC0832转换器采集充电电池的电压并在液晶LCD1602上显示充电电压值。此太阳能充电器制作简单，性价比高，性能稳定。

ABSTRACT

The source of the solar charger design is to convert solar energy into electricity, mainly to solve the technical problem is how to charge can convert solar energy into electricity.Solar energy as a renewable energy it has abundant, an inexhaustible, clean and safe characteristics and therefore has a broad application prospect, photovoltaic power generation technology is also more and more get the attention of people, with the price of photovoltaic modules and the decrease of the development of photovoltaic technology, solar photovoltaic power generation system will be gradually by the additional energy to make the transition to alternative energy now.

Solar charger, solar energy charging circuit is composed of single chip microcomputer minimum system, ADC0832 conversion module, the solar rechargeable batteries, liquid crystal display module and power module.Solar battery charging system is solar battery charging board in charge under the sun, the storage of solar panels charge, provide TP4056 chip after voltage chip voltage power supply and charging the battery.When charging, charging indicator light, when charging is completed, charging indicator light go out.Use of ADC0832 converter acquisition rechargeable battery voltage and displayed on the LCD LCD1602 charging voltage value.This solar charger, simple, cost-effective, stable performance.
