下面结合具体例子，更加详细地描述本发明实施例。应注意，图3至图4的例子仅仅是为了帮助本领域技术人员理解本发明实施例，而非要将本发明实施例限于所例示的具体数值或具体场景。本领域技术人员根据所给出的图3至图4的例子，显然可以进行各种等价的修改或变化，这样的修改或变化也落入本发明实施例的范围内。
图3是本发明实施例的快充开启过程的示例图。
如图3所示，闪充的开启过程一共包含五个阶段：
阶段1
当电源适配器检测到连续T1时间内输出电流大于等于I2时，认为移动 终端的电源适配器类型识别已经完成(即已经识别为其充电的是电源适配器，而非电脑等其他电器)，开启通信，发送指令1询问移动终端是否开启快充(或称闪充)。当电源适配器收到移动终端不同意闪充，则重复检测电流，当电流仍然大于等于I2时，再次发起请求，循环往复，直到移动终端答复同意快充或电流不再满足大于等于I2的条件。当移动终端同意闪充后，进入第2阶段。
阶段2
电源适配器发送指令2询问移动终端电源适配器的电压是否合适，得到移动终端答复偏高或偏低，则对应调整一格档位，再重新询问移动终端电源适配器的电压是否合适。反复循环直到移动终端答复合适位置后，进入第3阶段。
阶段3
当电源适配器收到移动终端答复电源适配器电压的合适后，发送指令3询问移动终端当前支持的最大充电电流，进入第4阶段。
阶段4，5
电源适配器根据移动终端答复的电流值，设置输出电流到指定值，进入恒流阶段。同时，电源适配器每间隔一段时间发送指令4，询问移动终端电池电压，并根据电池电压判断USB接触是否良好，以及是否需要降低充电电流。当电源适配器判断为USB接触不良，发送指令5，之后复位。
需要说明的是：
1)在阶段1中，移动终端回复指令1时，数据中可以附带终端通路阻抗，用于在阶段5判断USB接口的连接情况。
2)在阶段2中，从移动终端同意快充到电源适配器电压调整到合适值的时间可以控制在一定范围之内，防止移动终端判定为异常，停止快充。
3)在阶段2中，当电源适配器的电压调整到高于电池电压ΔV时，终端可以答复合适。(ΔV可以设置为200～500mA)
4)在阶段4中，电流的抬升速度可以控制一定范围之内，防止速度过快可能会出现闪充异常中断。
5)在阶段5中，恒流模式的电流控制精度可以尽量控制在5％以内。
6)在阶段5中，电源适配器实时监测通路阻抗，通过测量适配器电压，当前充电电流及读取的电池电压，算出整个快充通路的阻抗，当测出通路阻 抗>终端通路阻抗+闪充数据线阻抗时，认为USB连接不良，停止快充。
7)进入快充后每次通信的间隔可以控制在一定范围之内，防止会出现快充异常中断。
8)快充的终止可以分为可恢复和不可恢复两种。1、当移动终端检测到快充阶段电池充满或USB连接不良时，停止闪充，电源适配器可以不再开启闪充流程。2、当移动终端和电源适配器出现通信异常时，电源适配器可以停止快充，电源适配器停止后可以会重新开启快充流程。3、当移动终端检测到电池出现异常时，可以停止快充，待电池恢复正常后再重新开启快充流程。
下面结合图4，给出快速充电过程的一个示例。图4示出的整个流程与图3所描述的流程大致对应。
从图4可以看出，电源适配器一开始处于DCP模式，即D+、D-短接短路模式，采用普通充电模式为移动终端充电。在发送第一指令前，电源适配器还可以判断数据线是否为快充数据线，具体的判断方式有很多种，例如，在数据线中加识别电路，电源适配器通过与该识别电路进行信息交互识别该数据线是否为快充数据线。此外，还需要说明的是，在整个快充流程中，当出现通信异常或阻抗异常时，电源适配器可以退出快充流程或复位。
