Description

便携式移动电源 技术领域
本发明涉及电能存储系统，特别是涉及用于电池组的充电或去极化或用于由电池组向负载供电的装置，尤其涉及便携式移动电源。
背景技术
随着便携式电子装置(如智能手机、平板电脑等)的广泛应用，由于便携式电子装置的电池存在技术瓶颈，电池的续航能力非常有限，而便携式移动电源(俗称充电宝)自身具有储电单元可直接给便携式电子装置充电，且便携式移动电源方便携带，因此便携式移动电源的使用越来越广泛。
现有技术中，便携式移动电源可通过市电的交流电源实现充电，内部的电能存储单元存放电能，在必要时给移动设备充电；便携式移动电源相当于一个充电器和备用电池的混合体，相比于充电器具有电能存储单元，可作为其他外界其上的设备的充电电源。
但是，现有技术中的便携式移动电源作为充电器和备用电池的混合体，通常只有一种电平的输入和输出电压如5V；输入、输出分别由不同的接口来完成，必须具备两个或两个以上的接口一个充电接口和一个放电接口；获取电能的接口和电平单一，使用不便捷；限制了其获得电能的来源和渠道。
名词解释：OTG是On-The-Go的缩写,由USB Implementers Forum公布,主要应用于各种不同的设备或移动设备间的联接,进行数据交换的USB接口技术。
发明内容
本发明内容要解决的技术问题在于避免上述现有技术的不足之处而提出一种充电和放电使用同一接口的便携式移动电源。
