图2为本申请充电方法另一个实施例的流程图，如图2所示，本申请图1所示实施例中，步骤105可以包括：
步骤201，根据上述充电设备连接电子设备的充电口中最高优先级充电口所需的最小功率、上述充电设备的可用充电功率和优先级低于上述最高优先级的充电口所需的最小功率，确定第一功率范围。
步骤202，将上述第一功率范围内的第一充电功率分配给上述最高优先级充电口。
具体地，将上述第一功率范围内的第一充电功率分配给上述最高优先级充电口可以理解为：在第一功率范围内，基于最高优先级充电口，充电设备和上述电子设备进行充电功率协商，取相互支持的最大充电档位，将协商成功的功率作为第一充电功率分配给上述最高优先级充电口。
进一步地，步骤202之后，还可以包括：
步骤203，根据上述充电设备连接电子设备的充电口中次高优先级充电口所需的最小功率、上述充电设备的可用充电功率、上述第一充电功率和优先级低于上述次高优先级的充电口所需的最小功率确定第二功率范围。
步骤204，将第二功率范围内的第二充电功率分配给上述次高优先级充电口。
具体地，将第二功率范围内的第二充电功率分配给上述次高优先级充电口可以理解为：在第二功率范围内，基于次高优先级充电口，充电设备和上述电子设备进行充电功率协商，取相互支持的最大充电档位，将协商成功的功率作为第二充电功率分配给上述次高优先级充电口。
进一步地，步骤204之后，还可以包括：
步骤205，根据上述充电设备连接电子设备的充电口中最低优先级充电口所需的最小功率、上述充电设备的可用充电功率、上述第一充电功率和上述第二充电功率确定第三功率范围。
步骤206，将上述第三功率范围内的第三充电功率分配给最低优先级充电口。
具体地，将上述第三功率范围内的第三充电功率分配给最低优先级充电口可以理解为：在第三功率范围内，基于最低优先级充电口，充电设备和上述电子设备进行充电功率协商，取相互支持的最大充电档位，将协商成功的功率作为第三充电功率分配给上述最低优先级充电口。
本实施例中，充电设备可以包括A口、C口和无线充电端口这3个充电口，上述3个充电口的优先级可以按照充电口连接电子设备的先后顺序设定，例如：假设A口最先连接电子设备，也就是说，A口最先有电子设备接入，那么可以设定A口的优先级最高；或者，上述3个充电口的优先级可以预先设定，例如：可以预先设定C口的优先级最高，A口次之，无线充电端口优先级最低；本实施例对充电设备的充电口的优先级的设定规则不作限定，下面以充电口的优先级预先设定为例进行说明。
(1)适配器在位时，充电设备利用C口为自身进行充电，剩下A口和无线充电端口可以进行对外充电，这时为了保证充电设备的对外充电效率，如果适配器输入功率不满足对外充电所需的最大功率，则优先从充电设备的电池取电进行对外充电，这时充电设备的最大输出功率P MAX＝适配器输入功率+P BAT，充电设备的最大输出功率在减去对外充电所需的最大功率之后，如果还有剩余功率，则利用上述剩余功率给充电设备的电池进行充电；适配器在位时，A口为最高优先级充电口，无线充电端口为次高优先级充电口，也是优先级低于最高优先级的充电口，上述充电设备的可用充电功率在上述充电设备的充电口之间的分配方式可以如下：
A口：在[P AMIN,(P RMNG－P WMIN)]范围内取A口支持的最大的充电功率；
无线充电端口：在[P WMIN,(P RMNG－P ADST)]范围内取无线充电端口支持的最大的充电功率；
其中，P AMIN为A口所需的最小功率，P RMNG为上述充电设备的可用充电功率，P WMIN为无线充电端口所需的最小功率，[P AMIN,(P RMNG－P WMIN)]为第一充电范围，P ADST为A口对外充电时，最终分配的最大充电功率，即第一充电功率；而[P WMIN,(P RMNG－P ADST)]为第二充电范围，无线充电端口对外充电时，最终分配的最大充电功率为第二充电功率。
举例来说，适配器在位时，A口和无线充电端口同时对外充电，P BAT＝30.4W，在A口和无线充电端口之间进行功率分配时，为了兼容5V/1A的适配器，具体的功率分配方式可以如表1所示。
表1
Figure PCTCN2020128062-appb-000001
从表1可以看出，按照现有的预定规则进行功率分配，充电设备输出的有效功率为32.5W，而按照本申请提供的方法进行功率分配之后，充电设备输出的有效功率为37.5W，从而实现了根据充电设备中各充电口的优先级，调整各充电口的充电功率，使得充电设备的对外充电效率达到最大，提升了充电设备的充电效率。
(2)适配器不在位时，充电设备的对外充电端口包括：A口、C口和无线充电端口，适配器不在位时，C口为最高优先级充电口，A口为次高优先级充电口，无线充电端口为最低优先级充电口，A口和无线充电端口为优先级低于最高优先级的充电口，无线充电端口为优先级低于次高优先级的充电口，上述充电设备的可用充电功率在上述充电设备的充电口之间的分配方式可以如下：
C口：在[P CMIN,(P RMNG－P WMIN－P AMIN)]范围内取C口支持的最大的充电功率；
A口：在[P AMIN,(P RMNG－P CDST－P WMIN)]范围内取A口支持的最大的充电功率；
无线充电端口：在[P WMIN,(P RMNG－P CDST－P ADST)]范围内取无线充电端口支持的最大的充电档位；
其中，P CMIN为C口所需的最小功率，P AMIN为A口所需的最小功率，P WMIN为无线充电端口所需的最小功率，P RMNG为上述充电设备的可用充电功率，[P CMIN,(P RMNG－P WMIN－P AMIN)]为第一充电范围，P CDST为C口对外充电时，最终分配的最大充电功率，即第一充电功率；[P AMIN,(P RMNG－P CDST－P WMIN)]为第二充电范围，P ADST为A口对外充电时，最终分配的最大充电功率，即第二充电功率；[P WMIN,(P RMNG－P CDST－P ADST)]为第三充电范围，无线充电端口对外充电时，最终分配的最大充电功率为第三充电功率。
举例来说，适配器不在位时，C口和A口同时对外充电，为了兼容市面上5V/1A的适配器，具体的功率分配方式可以如表2所示。
表2
Figure PCTCN2020128062-appb-000002
从表2可以看出，按照现有的预定规则，充电设备可输出的有效功率28W，但如果C口连接的电子设备不支持快充，那么按照现有的预定规则进行功率分配之后，充电设备实际输出的有效功率为20W，而按照本申请提供的方法进行功率分配之后，充电设备输出的有效功率仍可达到28W，从而实现了根据充电设备中各充电口的优先级，调整各充电口的充电功率，使得充电设备的对外充电效率达到最大，提升了充电设备的充电效率。
