摘要:现在,随着化石燃料的使用加剧,化石燃料产生的污染越发严重,人们很关心周边生活的环境质量,寻找替代化石燃料的清洁能源变得非常迫切。而自从太阳能被使用后,大家发现它具有无污染、清洁干净取之不尽的特点,于是在生活生产各个方面进行使用。太阳能产品如今进入千家万户,能源,计算器,发电站很多行业都在使用这种清洁能源。高效利用太阳能是我们的目标,使用清洁能源保护环境更是势在必行。本次设计为便携式移动太阳能充电站,此次使用太阳能是经过电路产生的不稳定电流进行充电变换成非常稳定可靠的直流电流,于是决定使用单片机进行控制,并且能自动停止充电,电池完成充电时,也可作为一般直流电源使用,可以方便人们在户外充电,避免因为电量问题而造成生活上的不便。48727

Design and Fabrication of Mini Mobile Solar Charging Station
Abstract:Nowadays, with the increasing use of fossil fuels, the pollution caused by fossil fuels is becoming more and more serious, people are concerned about the quality of the environment around, and it is very urgent to find alternative fossil fuels to clean energy. Since the use of solar energy, we found that it has no pollution, clean and inexhaustible characteristics, so in all aspects of life and production to use.Solar products now enter thousands of households, cars, calculators, power stations in many industries are using this clean energy. Efficient use of solar energy is our goal, the use of clean energy to protect the environment is imperative.The design of portable solar charging station, in order to use solar energy is generated through the circuit unstable current charging transform into very constant DC current and decided to use single-chip microcomputer to control, and can automatically stop charging, the battery is fully charged, and can also be used as a general DC power supply, can be convenient for people in outdoor charging, avoid because of power problems caused inconvenience to life.
