基于闲置手机锂电池的多功能移动电源

手机更新换代的速度不断加快,由于不同手机锂电池规格迥异,导致更换手机后大量仍有使用价值的手机锂电池被闲置下来,造成巨大的资源浪费,或遭填埋而造成严重的环境污染。根据手机锂电池自身的充放电特点,提出一种多功能移动电源的设计方案。该多功能移动电源以手机锂电池作为电芯,以一个5 V Micro USB端口作为充电输入端,通过两个USB端口对外输出3.7、5 V两种电压,以满足不同电子设备的需求。由于实物模型制造成本低廉且实用性强,该方案具有较高的应用推广价值。

Multifunctional movable power based on idle cellular Li-ion battery

With the rapid development of mobile phone technologies,the frequency of changing mobile phones are getting faster and faster,lots of useable cellular Li-ion batteries being idle because of cellular Li-ion batteries of utterly different size,which leads to tremendous wasting of resources and serious environmental pollution if Li-ion batteries are buried.Based on the charge-discharge characteristics of cellular Li-ion batteries,the multifunctional movable power was designed,which can charge cellular Li-ion batteries by a 5 V micro USB input port and can output 3.7 or 5 V voltage by two USB output ports to satisfy the electricity demand of different electronic devices.Due to low manufacturing cost and strong practicality of the physical model,the multifunctional movable power has promising future.
