可供便携式设备充电的移动电源设计

摘要

Due to the limit of battery’s energy capacity,protable device can’t be used long time without charging. The mobile power is designed to give the energy to other protable devices in the open air. Base on the Li battery charge IC of ASC8513 and boost converter IC of ME2109 , both the charging current and output current of this mobile power can reach 2 A, higher than ordinary products twice. The mobile power have good security and humanized design. Analysing the system design, parameter settings and work efficiency this design provides a solution for the a high performance mobile power.%针对便携式设备续航时间短的问题,设计了一款能够在户外供其他移动数码产品充电的移动电源。此款移动电源基于锂电池充电芯片ASC8513和升压芯片ME2109,能做到自身的充电电流和输出电流均达到2 A,比普通产品的1 A电流高出1倍,并具有很好的安全性和人性化设计。着重分析了移动电源系统中各模块的电路设计,参数设置和工作效率等问题,为设计一款性能优良的移动电源提供了解决方案。
