Abstract

一种充电电路(113)、终端设备(11)、适配器(14)、充电系统(10)及方法，主要应用于终端设备(11)充电过程，该终端设备(11)可以使用无电解电容的适配器(14)充电，从而有利于适配器小型化。在终端设备(11)的充电接口(111)的电压较低时，该充电电路(113)可以利用终端电池(112)放电，以维持充电接口(111)的电压，该充电电路(113)也可以降低提供给终端电池(112)的充电电流，以维持充电接口(111)的电压。由于充电接口(111)的电压可以等效于适配器(14)的输出接口的电压，因此该充电电路(113)可以维持适配器(14)的输出接口的电压不至于过低，有利于防止适配器(14)停止工作。
