具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清 楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。

下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的参数调整方案进行详细地说明。
参照图1，示出了本申请实施例一提供的一种充电方法的步骤流程图，如图1所示，该充电方法具体可以包括如下步骤：
步骤101：在采用第一充电电路和至少一个第二充电电路进行充电的过程中，获取所述第一充电电路和所述至少一个第二充电电路之间的设定参数差值。
其中，在采用第一充电电路(Integrated circuit，IC)和至少一个第二IC进行充电的过程中，可以实时检测第一IC和至少一个第二IC之间的设定参数的差值，其中设定参数包括输入电流值、输出电压值或输入功率值，并且实时计算参数差值，在设定参数为输入电流值的情况下，计算输入电流差值，在设定参数为输出电压值的情况下，计算输出电压差值，在设定参数为输入功率值的情况下，计算输入功率差值。
在采用第一充电电路和至少一个第二充电电路进行充电的过程中，获取所述第一充电电路和所述至少一个第二充电电路之间的设定参数差值之后，执行步骤102。
步骤102：在所述设定参数差值大于预设参数差值的情况下，控制充电器降低输出电压。
其中，预设参数差值包括预设输入电流差值、预设输出电压差值、预设输入功率差值中的任一种。具体地，关于预设参数差值的具体数值，可以根据业务需求进行设置，本实施例对此不加以限制。
在设定参数差值大于预设参数差值时，说明第一IC和至少一个第二IC之间的参数差值较大，可能会导致集成电路发热或无法正常工作，因此，在本申请中，可以通过差分信号(D+/D-)发送控制命令，以控制充电器降低输出电压。
具体地，可以控制充电器降低输出电压(V 请求)一个步进电压(V STEP)，以得到的输出电压(V)，也即是，V＝V 请求—V STEP。
其中，V 请求是电子设备请求充电器的输出电压。V STEP是电子设备请求充电器改变的步进电压，也即是充电器的输出电压达不到电子设备的请求电压后，电子设备需要增加一个步进电压，如果增加一个步进电压后，电子设备还未达到所需电压，电子设备就再增加一个步进电压。
降低了充电器的输出电压，则使得流入电子设备的总电流就减小，而第一IC和至少一个第二IC通路的阻抗不会发生变化，则可以使得第一IC和至少一个第二IC电流的差值变小。
图2示出了本申请实施例提供的一种输出电压和电流的示意图，如图2所示，在总输入电流为I，电阻RI和IC1串联，其IC1支路的电流为I1，电阻R2和IC2串联，其IC2支路的电流为I2，电阻RI和电阻R2并联，则示例的，在总电流I为6安培(A)，I1为4A，I2为2A，可以得到RI：R2＝2:1，|I1-I2|＝2A；则在总阻抗不变的情况下，输出电压降低，则总输出电流变小，示例的，当总输出电流变为3A，R1:R2＝2:1可得I1＝2AI2＝1A此时|I1-I2|＝1A，也即是，使得参数差值变小。
可以理解地，上述示例仅是为了更好地理解本申请实施例的技术方案而列举的示例，不作为对本实施例的唯一限制。
在所述设定参数差值大于预设参数差值的情况下，控制充电器降低输出电 压之后，执行步骤103。

进一步的，在一种可选的实施例中，可以在检测到降低后的输出电压值达到预设电压值，且对应的所述设定参数差值大于预设参数差值的情况下，进行下一次获取所述设定参数差值，并控制充电器降低输出电压的步骤。
具体地，可以先预先设置一个较低的预设参数差值，在输出电压值降低至该预设参数差值之后，才启动循环步骤，对设定参数差值进行检测。
循环执行步骤101至步骤102，控制充电器降低输出电压，在该过程中，如果检测到设定参数差值小于或者等于预设参数差值的情况下，则控制充电器使用第一IC和至少一个第二IC进行充电，通过降低输出电压，使得第一IC和至少一个第二IC分到的电流尽量相同，使得，第一IC和至少一个第二IC的输入电压尽量相同，使得整体充电方案发热均匀，可以提高用户的充电体验。

设定次数可以是2次，还可以是3次，也可以是4次等，本申请实施例对此不作具体限定，可以根据实际应用场景做具体的标定调整。
在循环执行设定次数的控制充电器降低输出电压之后，可以获取第一IC和至少一个第二IC之间的设定参数差值。其中设定参数包括输入电流值、输 出电压值或输入功率值，在设定参数为输入电流值的情况下，计算输入电流差值，在设定参数为输出电压值的情况下，计算输出电压差值，在设定参数为输入功率值的情况下，计算输入功率差值。在设定参数差值大于预设参数差值的情况下，说明控制充电器降低输出电压设定次数后，第一IC和至少一个第二IC之间的参数差值仍然较大，可能会导致集成电路发热或无法正常工作，此时为了保持快充的充电体验，则关闭不满足预设充电条件的第一IC，并采用至少一个满足预设充电条件的第二IC进行充电，避免出现IC由于参数差值较大而出现的发热不均，以及IC由于参数不均而导致的IC损坏的情况，提高了IC的使用稳定性和使用寿命，进一步的，提高了电子设备的稳定性和安全性。
其中，不同的充电方式对应有不用的预设充电条件，示例的，半压快充的预设充电条件包括：IC的输入电压必须是输出电压的两倍，本申请实施例在此不一一举例。

其中，V 请求是电子设备请求充电器的输出电压。V STEP是电子设备请求充电器改变的步进电压，也即是充电器的输出电压达不到电子设备的请求电压后，电子设备需要增加一个步进电压，如果增加一个步进电压后，电子设备还未达到所需电压，电子设备就再增加一个步进电压。
降低了充电器的输出电压，则使得流入电子设备的总电流就减小，而第一IC和至少一个第二IC通路的阻抗不会发生变化，则可以使得第一IC和至少一个第二IC电流的差值变小。
在所述设定参数差值大于所述预设参数差值的情况下，控制所述充电器降低输出电压之后，执行子步骤A4。

子步骤A6：在所述设定参数差值大于所述预设参数差值的情况下，关闭所述第一充电电路，并采用所述至少一个第二充电电路进行充电直至充电完成。
在设定参数差值大于预设参数差值的情况下，说明控制充电器降低输出电压设定次数后，第一IC和至少一个第二IC之间的参数差值仍然较大，可能会导致集成电路发热或无法正常工作，此时为了保持快充的充电体验，则关闭不满足预设充电条件的第一IC，并采用至少一个满足预设充电条件的第二IC进行充电直至充电完成，避免出现IC由于参数差值较大而出现的发热不均，以及IC由于参数不均而导致的IC损坏的情况，提高了IC的使用稳定性和使用寿命，进一步的，提高了电子设备的稳定性和安全性。
步骤205：在循环执行上述步骤的次数或时间满足预设条件的情况下，若所述设定参数差值小于所述预设参数差值，则采用所述第一充电电路和至少一个所述第二充电电路进行充电。
在循环执行上述步骤的次数或时间满足预设条件的情况下，若所述设定参数差值小于所述预设参数差值，则控制充电器使用第一IC和至少一个第二IC进行充电，通过降低输出电压，使得第一IC和至少一个第二IC分到的电流尽量相同，使得，第一IC和至少一个第二IC的输入电压尽量相同，使得整体充电方案发热均匀，可以提高用户的充电体验。
