为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施方式作进一步地详细描述。文中所讲的“电子设备”可以包括平板电脑、智能电视、膝上型便携计算机、台式计算机、电子烟等等。
请参考图1，其示出了本发明一个实施例提供的充电控制方法的方法流程图，本实施例以该充电控制方法用于电子设备中来举例说明。如图1所示，该充电控制方法可以包括：
步骤110，在与外部供电设备相连接时，确定外部供电设备提供的充电电流能否满足电池组件内全部电池同时充电的充电需求。
其中，外部供电设备可以为移动电源、充电器等等，本实施例对此不做具体限定；该电池组件包括至少两个电池。
可选的，确定外部供电设备提供的充电电流能否满足电池组件内全部电池同时充电的充电需求：检测充电电流与基准电流之间的大小关系；在充电电流达到基准电流时，判定充电电流与电池数量匹配，充电电流不满足上述充电需求；在充电电流低于基准电流时，判定充电电流与电池数量不匹配，充电电流不满足上述充电需求。可选的，该基准电流可以为充电标准下k节电池同时充 电所需的充电电流，k为正整数且小于电池组件内电池的数量。
其中，基准电流可以为一节电池充电所需要的充电电流，例如一节3.7v可充电锂电池所需要的充电电流1A；在电池组件内电池数量大于或等于2的情况下，系统开发人员可选定k节串联电池一同充电时所需的充电电流，k≥2且k小于电池组件内电池数量。
举例来讲，如果电子设备内电池组件包括串联的两节3.7V可充电锂电池，则该电子设备内的基准电流可以为1A；电子设备内电池组件包括串联的3节3.7V可充电锂电池，则该电子设备内的基准电流可以为1A，也可以为2.1A。
在外部供电设备提供的充电电流达到基准电流时，表明外部供电设备与电池组件匹配，外部供电设备能够同时给电池组件内所有电池充电。
可选的，检测充电电流与基准电流之间的大小关系可通过以下方式实现：
第一种，电子设备内设置用于检测充电电流的检测组件；电子设备内微控制单元获取检测组件检测到充电电流的电流值；检测该电流值与预存储的基准电流的大小关系。
第二种，电子设备内设置有电流比较组件，该电流比较组件的输出端与电子设备的微控制单元相连接；该电流比较组件的两个输入端中的一个与电池组件电连接且接地，另一个与基准电流对应基准电压的提供端电连接；微控制单元根据电流比较组件输出的电平确定充电电流与基准电流之间的大小关系。
具体的：在电流比较组件的正向输入端与电池组件电连接，负向输入端与基准电压的提供端电连接的情况下：电流比较组件在充电电流达到基准电流时输出高电平，电流比较组件在充电电流低于基准电流时输出低电平，因此微控制单元在电流比较组件输出的电平为高电平时判定充电电流达到基准电流，在电流比较组件输出的电平为低电平时判定充电电流低于基准电流。
在电流比较组件的正向输入端与基准电压的提供端电连接，负向输入端与电池组件电连接的情况下：控制单元在电流比较组件输出的电平为低电平时判定充电电流达到基准电流，在电流比较组件输出的电平为高电平时判定充电电流低于基准电流。
步骤120，如果充电电流不满足该充电需求，则向外部供电设备发送电流增大信号，或者，将充电电流提供给电池组件中的部分电池。
其中，在外部供电设备本身存在至少两个电流档位的情况下，该外部供电 设备可根据该电流增大信号升高电流档位，以提高充电电流。以外部供电设备与电子设备相连接时电流档位为1、充电电流为1A来举例说明，如果电子设备的电池组件包括两节3.7V的可充电锂电池，则该电池组件对应的基准电流可以为1A，电子设备可向外部供电设备发送电流增大信号，以触发外部供电设备根据该电流增大信号升高电流档位至2、充电电流为2.1A。
可选的，将充电电流提供给电池组件中的部分电池之前，可展示用于提示外部供电设备的充电电流过小的提示信息，以便用户根据该提示信息调节外部供电设备的电流档位或者更换外部供电设备。如果在展示该提示信息后的预定时长内未检测到充电电流达到基准电流，则将充电电流提供给电池组件中的部分电池。
其中，该提示信息的展示方式可以包括文字提示、语音提示、指示灯提示、蜂鸣器报警、预定时长倒计时等等，本实施例对此不作具体限定。
可选的，将充电电流提供给电池组件中的部分电池的实现可以为：将该充电电流提供给该电池组件包括的至少两个电池中的一个。具体实现可以为：获取电子设备内电池组件中每个电池的电池电压；将该充电电流提供给该至少两个电池中电池电压最小的一个。
可选的，在电池组件包括2个电池组成的情况下，将该充电电流提供给该电池组件中的一个电池的实现电路可参考图2，如图2所示，电子设备的电池组件包括第一电池C1和第二电池C2，其中：第一电池C1的第一端与第一开关K3的第一端相连接，第一开关K3的第二端与电子设备的充电电流输入端电连接，第一开关K3的第二端与第一电池C1的第二端之间串联有第二开关K1；第一电池C1的第二端与第二电池C1的第一端之间串联有第三开关K4，第一电池C1的第二端与第二电池C1的第二端串联有第四开关K2。则在给第一电池C1充电时，控制第一开关K3、第四开关K2闭合，以及控制第二开关K1、第三开关K4断开；在给第二电池C2充电时，控制第二开关K1、第三开关K4闭合，以及控制第一开关K3、第四开关K2断开。也就说，可通过控制第一开关K3、第二开关K1、第三开关K4以及第四开关K2的断开与闭合，将外部充电设备提供的充电电流提供给第一电池C1和第二电池C2中的任一个。
其中，本申请所涉及的充电电流输入端可以为电子设备的充电接口中的正极输入端，例如USB接口中的正极输入端。
可选的，在电池组件包括3个电池组成的情况下，将该充电电流提供给该电池组件中的一个电池的实现电路可参考3，如图3所示，电子设备的电池组件包括第一电池C1、第二电池C2和第三电池C3，其中：第一电池C1的第一端与第一开关K3的第一端相连接，第一开关K3的第二端与电子设备的充电电流输入端电连接，第一开关K3的第二端与第一电池C1的第二端之间串联有第二开关K1；第一电池C1的第二端与第二电池C1的第一端之间串联有第三开关K4，第一电池C1的第二端与第二电池C1的第二端串联有第四开关K2；第二电池C2的第二端与第三电池C3的第一端之间串联有第五开关K5，第二电池C2的第二端与第三电池C3的第二端串联有第六开关K6。
可通过控制第一开关K3、第二开关K1、第三开关K4、第四开关K2、第五开关K5以及第六开关K6的断开与闭合，将充电电流提供给第一电池C1、第二电池C2、第三电池C3中的一个、两个或三个。
举例来讲，在给第一电池C1充电时，控制第一开关K3、第四开关K2以及第六开关K6闭合，以及控制第二开关K1、第三开关K4以及第五开关K5断开；再举例来讲，在给第二电池C2充电时，控制第二开关K1、第三开关K4闭合以及第六开关K6，以及控制第一开关K3、第四开关K2断开；再举例来讲，在给第三电池C3充电时，控制第二开关K1、第四开关K2、第五开关K5闭合，以及控制第一开关K3、第三开关K4、第六开关K6断开。再举例来讲，在给第一电池C1、第二电池C2同时充电时，控制第一开关K3、第三开关K4、第六开关K6闭合，以及控制第二开关K1、第四开关K1、第五开关K5断开。
可选的，如果充电电流满足上述充电需求，将该充电电流提供给电池组件内全部电池。
举例来讲，如图3所示，控制第二开关K1、第四开关K2以及第六开关K6断开，以及控制第一开关K3、第三开关K4以及第五开关K5闭合；举例来讲，如图2所示，控制第二开关K1、第四开关K2断开，以及控制第一开关K3、第三开关K4闭合。
可选的，如果充电电流高于电池组件充电时的安全阈值，则控制外部供电设备停止向电池组件提供充电电流。具体实现可以为：控制外部供电设备与电池组件之间的通路断开，以停止外部供电设备停止向电池组件提供充电电流。其中，安全阈值通常由系统开发人员设定。
综上所述，本发明实施例提供的方法，通过在与外部供电设备相连接时，确定外部供电设备提供的充电电流能否满足电池组件内全部电池同时充电的充电需求；如果充电电流不满足该充电需求，则向外部供电设备发送电流增大信号，或者，将充电电流提供给电池组件中的部分电池；解决了相关技术中给电子设备充电的充电器与该电子设备不适配导致的无法充电、充电速度慢的问题；达到了提高充电效率的效果。
可选的，电子设备内设定有i个基准电流，i的取值小于电池组件内电池数量且大于1。其中，i个基准电流由开发人员设定，例如开发人员在设定第i个基准电流时可根据充电标准下i个电池数量所需的充电电流设定。
则步骤110的实现可以为：获取电子设备内充电组件中电池数量；获取i个基准电流中第n个基准电流，n＝电池数量-1，检测外部供电设备提供的充电电流与该第n个基准电流之间的大小关系。
举例来讲，如果电池组件内电池数量为3，则可获取第2个基准电流，也即充电标准下给两个串联的电池同时充电所需要的充电电流；如果外部供电设备提供的充电电流达到第2个基准电流，则表明外部供电设备与电池组件匹配，外部供电设备能够同时给电池组件内所有电池充电。
可选的，以上实施例以在充电电流电池组件中电池数量与充电电流不匹配情况下，将充电电流提供给电池组件中的一个电池来举例说明。可选的，步骤120的实现还可以为：根据该充电电流的取值确定该充电电流支持的同时充电的电池数量，也即，该外部供电设备支持的同时充电的最大电池数量；向电池组件中该电池数量的电池提供充电电流。
其中，根据该充电电流的取值确定该充电电流支持的同时充电的电池数量的实现可以为：电子设备内设定有i个基准电流，第i个基准电流根据充电标准下i个电池数量所需的充电电流设定；如果充电电流的取值达到第a-1个基准电流且低于第a个基准电流，则向电池组件中a-1个电池提供该充电电流。
以i＝3，a＝3来举例说明，请参考图3，如果充电电流的取值达到第2个基准电流2.1A且低于第3个基准电流，则向电池组件中2个电池提供该充电电源。具体的，获取电池组件内3个电池的电池电压，如果第三电池、第二电池的电池电压均达到第一电池电压，则控制第三开关K4、第五开关K5、第二开关K1 闭合以及控制第四开关K2、第一开关K3以及第六开关K6断开。
其中，向电池组件中该电池数量的电池提供充电电流的实现可以为：获取该电池组件中每个电池的电池电压；根据电池电压由低至高的顺序对该电池组件内的电池进行排序，将该充电电流提供给排序在前的m个电池，m为正整数且小于电池组件中电池的数量；或者，根据电池电压由高至低的顺序对该电池组件内的电池进行排序，将该充电电流提供给排序在后的m个电池，m等于该外部供电设备支持的同时充电的最大电池数量。
