技术问答

都是快充为何不通用？根据“P=UI”公式，提升手机充电功率无非就是增大输入电流或输入电压的大小。但是，到底是以提升电压为主，还是增大电流为主，又或是二者同时增加？

由于业内没有统一的共识，逐渐衍生出了高通QuickCharge（QC）、联发科Pump Express（PE）、华为Fast Charge Protoco（FCP）和USB PD等快充标准。

目前手机端存在的快充协议主流的有USB PD、QC、AFC、FCP、SCP、VOOC、SuperVOOC、PE、FlashCharge等；

因为快充是需要充电器端、连接线材以及设备接收端都支持快充才可以进行快充通讯的，如果非要把以上的快充普及度排名的话，应该是PD/QC>FCP>SCP>VOOC>AFC>SuperVOOC>PE>FlashCharge。要想正确激活手机的快速充电功能，手机、充电器和数据线这三要素的搭配就显得尤为重要。

手机圈的快充方案有很多，这就导致了不同型号手机和充电器之间的兼容性问题。简单来说，手机内集成有电源管理IC、充电器内也集成了专用的识别IC，当手机和充电器通过数据线连接，两颗IC芯片相互识别认证并成功“握手”之后才能激活快充功能（图9），即充电器端按照手机端发出的升压或降压的信号实时调整电压/电流参数。如果IC芯片之间认证失败，充电器就只能保持默认的5V/2A输出了。
