附图说明
为了更清楚地说明本申请实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

图2为本申请实施例1提供的一种电子设备结构示意图；
图3为本申请实施例9提供的一种充电控制方法过程示意图；

图5为本申请实施例11提供的一种充电控制方法过程示意图。
具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图本申请作进一步地详细描述，显然，所描述的实施例仅仅是本申请的一部分实施例，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做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。
图2为本申请实施例提供的一种电子设备结构示意图，所述电子设备包括主控单元201，还包括至少两个快充充电电路202和电池203，电池203中包含电芯211及与所述快充充电电路数量相同的充放电接口212和保护电路213，充放电接口212为电池的正负极接口；其中，
每个快充充电电路202通过电池203的一个充放电接口212与对应的保护电路213、电芯211依次连接，每个快充充电电路202与适配器204连接；
主控单元201，用于控制至少两个快充充电电路202上电为所述电池203充电，并向适配器204发送第一电压控制信号，控制所述适配器204输出第一固定电压，其中所述第一固定电压大于电池203工作电压。
具体的，在本申请实施例中，电子设备中包括至少两个快充充电电路202和电池203， 其中该电池203包括电芯211、与所述快充充电电路202数量相同的充放电接口212和保护电路213，每个快充充电电路202通过电池203的一个充放电接口212与对应的保护电路213、电芯211依次连接。在对电池203进行快速充电(快充)时，主控单元201控制至少两个快充充电电路202上电，并向适配器204发送第一电压控制信号，控制所述适配器204输出第一固定电压，为所述电池203充电，其中为了保证对电池的正常充电，所述第一固定电压大于电池203工作电压。
为了实现对电池的电芯的快速充电，需要增大电池的电芯的充电电流，但是随着充电电流的增大，快充充电电路和保护电路的发热增加，例如：采用普通方式充电(普充)时，快充充电电路电阻为R1和保护电路的电阻为R2，充电电压为V时对应的充电电流为I，此时普充快充充电电路的发热功率为I2R1、保护电路的发热功率为I2R2，发热总功率为I2R1+I2R2。现有快充方式中为了对电池的电芯的快速充电，将充电电流增大为2I，此时快充充电电路的发热功率为(2I)2R1、保护电路的发热功率为(2I)2R2，发热总功率为(2I)2R1+(2I)2R2，发热是普充的4倍。因为本申请实施例中电池电芯和适配器之间并联有至少两个依次连接的快充充电电路、电池的一个充放电接口与对应的保护电路，例如是两个依次连接的快充充电电路、电池的一个充放电接口与对应的保护电路并联在电池的电芯和适配器之间，当对电池的电芯的充电电流为2I时，流经每路的快充充电电路和对应保护电路的电流为I，每个快充充电电路的发热功率为I2R1、保护电路的发热功率为I2R2，发热总功率为2(I2R1+I2R2)，发热是普充的2倍，在对电池的电芯以同样充电电流2I进行快速充电时，发热功率是现有快充方式的二分之一，在对电池的电芯快速充电的同时降低了快充充电电路和保护电路的发热，防止了因快充充电电路和保护电路过热造成快充充电电路和保护电路的损毁。
并且随着电池电芯和适配器之间并联的依次连接的快充充电电路、电池的一个充放电接口与对应的保护电路数量的增多，为了达到相同的充电效果，流经每个快充充电电路和保护电路的充电电流减小，每个快充充电电路和保护电路的发热功率减小，发热总功率减小。例如：电池电芯和适配器之间并联有四个依次连接的快充充电电路、电池的一个充放电接口与对应的保护电路，对电池的电芯的充电电流为2I，流经每个快充充电电路和保护电路的充电电流为I/2，每个快充充电电路的发热功率为(I/2)2R1、保护电路的发热功率为(I/2)2R2发热总功率为4((I/2)2R1+(I/2)2R2)，在对电池的电芯以同样充电电流2I进行快速充电时，发热功率与普充相同，是现有快充方式时的四分之一，进一步降低了充放电保护电路的发热。
由于在本申请中，电子设备中包括至少两个快充充电电路和电池，在对电池充电时，主控单元控制至少两个快充充电电路上电为所述电池充电，增大了电池的充电电流，提高了充电效率，满足了用户的需求。
实施例2：
为了便于对电池两端的电压及流经保护电路的电路的电流的检测，保护电路213包括电量计量电路，所述电量计量电路用于检测电池两端的电压值及流经其所在的保护电路213的电流值，主控单元201通过与所述电量计量电路通信获取所述电量计量电路检测到的电压值和电流值。
具体的，在每个所述充放电接口中还包括所述电量计量电路的通信接口。通过每个充点电接口，主控单元可以获取电量计量电路检测到的电压值和电流值。
位于每个保护电路的电量计量电路，用于检测电池203两端的电压值及流经其所在的保护电路213的电流值，主控单元201通过与电量计量电路通信获取电量计量电路检测到的电压值和电流值，并根据流经每个保护电路的电流值，确定通过上电的该至少两个快充充电电路202为所述电池203充电的电流值。
实施例3：
为了提高充电效率，在上述各实施例的基础上，在本申请实施例中，主控单元201，还用于向适配器204发送第二电压控制信号，控制适配器204按照设定的第一电压增值基于所述第一固定电压增大输出电压以使所述上电的快充充电电路202的第一电流值增大。
具体的，在向电池充电时，可以以第一固定电压向电池充电，因为该第一固定电压大于电池工作电压，所以可以保证可以不断增加电池电量。
为了进一步提高充电的效率，在本申请实施例中通过增加与快充充电电路202连接的适配器204的输出电压，可以增加流经每个上电的快充充电电路202的电流，从而增大对电池203进行充电的电流。
在本申请实施例中，主控单元201还可以向适配器204发送第二电压控制信号，控制适配器204在所述第一固定电压的基础上按照第一电压增值，增大适配器204的输出电压，使通过上电的快充充电电路202的第一电流值增大，所述第一电压增值可以为0.2V、0.3V、0.5V等固定的电压值。例如：第一固定电压值为8V，第一电压增值为0.2V，控制适配器204按照0.2V的步进增大适配器204的输出电压。
其中在适配器根据第一电压增值，在第一固定电压的基础上，增大输出电压时，可以是以预设的时间间隔增大的，该时间间隔可以预先设定，例如可以是5s，10s，一分钟等。
随着适配器204输出电压的增大，为电池203充电的电流也随之增大，为了防止电流增大过快对电池203造成损坏，从而影响电池203的正常使用，在上述各实施例的基础上，在本申请实施例中，主控单元201，还用于获取流经上电的快充充电电路202的第一电流值，如果所述第一电流值达到预设的第一电流阈值，向适配器204发送第三电压控制信号，控制适配器204按照设定的第二电压增值增大输出电压以使所述上电的快充充电电 路202的第二电流值增大，其中，所述第二电压增值小于所述第一电压增值，所述第二电流值大于所述第一电流值。
具体的，在主控单元201控制适配器204按照设定的第一电压增值基于所述第一固定电压增大输出电压后，主控单元201获取流经所述上电的快充充电电路202的第一电流值。其中主控单元201与每条快充充电电路连接，主控单元201可以作为该快充充电电路中的一个元件，因此主控单元201可以自身具有电流统计功能，统计流经每条上电的快充充电电路的电流；另外，主控单元可以通过与电路计量电路的通信，获取流经每条上电的快充充电电路的电流。其中主控单元201获取的流经上电的快充充电电路202的第一电流值，可以是分别流经每个上电的快充充电电路202的电流值，也可以是上电的快充充电电路202中的任一一个的电流值，也可以是流经每个上电的快充充电电路202的电流总值。
因为每个快充充电电路的电路结构可知，因此每个快充充电电路的阻抗关系已知，可以根据每个快充充电电路设定第一电流阈值，也可以针对上电的快充充电电路的个数设定第一电路阈值。其中该第一电流阈值小于对应的额定电流值。例如对电池203快充时的总的额定电流为8A，第一电流阈值可以设置为5A、6A等。
较佳地，每个快充充电电路的电路结构相同，则可以只设置一个快充充电电路设定第一电流阈值，如果获取的是流经每个上电的快充充电电路202的电流总值，则根据上电的快充充电电路的数量，确定其对应的第一电流阈值。只要保证获取的第一电流值与采用的第一电流阈值对应即可。
如果第一电流值达到预设的第一电流阈值，此时控制适配器降低电流增速，向所述适配器204发送第三电压控制信号，控制所述适配器204按照设定的第二电压增值增大输出电压以使所述上电的快充充电电路202的第二电流值增大，其中，所述第二电压增值小于所述第一电压增值，所述第二电流值大于所述第一电流值。
因为对电池203快充时的额定电流是一定的，当对电池203的充电电流达到额定电流时，需要停止充电电流的增大，即控制适配器204停止增大输出电压，防止对电池203充电的电流过大造成电池203的损坏。主控单元201，还用于获取流经上电的快充充电电路202的第二电流值；如果所述第二电流值达到预设的第二电流阈值，向适配器204发送第四电压控制信号，控制适配器204输出第二固定电压以使电池203两端的第一电压值增大，其中所述第二电流阈值大于所述第一电流阈值，所述第二固定电压大于所述第一固定电压。
具体的，第二电流阈值可以是其对应的额定电流值，当主控单元判断第二电流值达到预设的第二电流阈值时，则说明对电池203充电的电流达到对电池203充电的额定电流，主控单元向适配器204发送第四电压控制信号，控制所述适配器204输出第二固定电压，对电池203进行充电。此时适配器以第二固定电压向电池充电，在不断充电的过程中，电 池203两端输出的第一电压值不断增大。
实施例4：
电池的电量饱和时，其两端的输出电压一定，如果此时还给电池充电，将会造成电池的损坏，因此为了保护电池，延长电池的寿命，在上述各实施例的基础上，在本申请实施例中，所述主控单元201，还用于获取电池203两端的第一电压值；如果所述第一电压值达到预设的第一电压阈值，向适配器204发送第五电压控制信号，控制适配器204按照设定的第二电压增值减小输出电压，其中所述第二电压增值小于所述第一电压增值。
具体的，该第一电压阈值可以为不大于电池的电量饱和时的输出电压，如果电池两端输出的第一电压达到预设的第一电压阈值，则说明电池203当前电量已经接近于饱和，此时控制适配器204减小向快充充电电路输出的输出电压，减小电池203的充电电流，避免电池过充的损坏。
实施例5：

实施例8：
本申请实施例提供了一种基于上述电子设备的充电控制方法，该方法应用于电子设备中的主控单元，该方法包括：
控制至少两个快充充电电路上电为所述电池充电，并向所述适配器发送第一电压控制信号，控制所述适配器输出第一固定电压，其中所述第一固定电压大于电池工作电压。
具体的，在对电池进行快充时，通过控制至少两个快充充电电路上电，并向适配器发送第一电压控制信号，控制所述适配器输出第一固定电压，为所述电池充电。为保证对电池的正常充电，所述第一固定电压大于电池的工作电压。
由于在本申请中，在对电池充电时，通过至少两个快充充电电路上电为所述电池充电，增大了对电池的充电电流，提高了充电效率，满足了用户的需求。
实施例9：
为了提高充电效率，在上述各实施例的基础上，在本申请实施例中，所述方法还包括：
向所述适配器发送第二电压控制信号，控制所述适配器按照设定的第一电压增值基于所述第一固定电压增大输出电压以使所述上电的快充充电电路的第一电流值增大。
具体的，在向电池充电时，可以以第一固定电压向电池充电，因为该第一固定电压大于电池工作电压，所以可以保证可以不断增加电池电量。
为了进一步提高充电的效率，在本申请实施例中通过增加与快充充电电路连接的适配器的输出电压，可以增加流经每个上电的快充充电电路的电流，从而增大对电池进行充电的电流。
在本申请实施例中，通过还可以向所述适配器发送第二电压控制信号，控制所述适配器在所述第一固定电压的基础上按照第一电压增值，增大所述适配器的输出电压，使通过上电的快充充电电路202的第一电流值增大，所述第一电压增值可以为0.2V、0.3V、0.5V等固定的电压值。例如：第一固定电压值为8V，第一电压增值为0.2V，控制适配器204按照设定的时间间隔以每次0.2V的步进增大适配器204的输出电压。
其中在适配器根据第一电压增值，在第一固定电压的基础上，增大输出电压时，可以是以预设的时间间隔增大的，该时间间隔可以预先设定，例如可以是5s，10s，一分钟等。
随着适配器输出电压的增大，为电池充电的电流也随之增大，为了防止电流增大过快对电池造成损坏，从而影响电池的正常使用，在上述各实施例的基础上，在本申请实施例中，所述方法还包括：
获取流经所述上电的快充充电电路的第一电流值；
如果所述第一电流值达到预设的第一电流阈值，向所述适配器发送第三电压控制信号，控制所述适配器按照设定的第二电压增值增大输出电压以使所述上电的快充充电电路的第二电流值增大，其中，所述第二电压增值小于所述第一电压增值，所述第二电流值大于所述第一电流值。

因为每个快充充电电路的电路结构可知，因此每个快充充电电路的阻抗关系已知，可以根据每个快充充电电路设定第一电流阈值，也可以针对上电的快充充电电路的个数设定第一电路阈值。其中该第一电流阈值小于对应的额定电流值。例如对电池203快充时的 总的额定电流为8A，第一电流阈值可以设置为5A、6A等。
较佳地，每个快充充电电路的电路结构相同，则可以只设置一个快充充电电路设定第一电流阈值，如果获取的是流经每个上电的快充充电电路的电流总值，则根据上电的快充充电电路的数量，确定其对应的第一电流阈值。只要保证获取的第一电流值与采用的第一电流阈值对应即可。
如果第一电流值达到预设的第一电流阈值，此时控制适配器降低电流增速，向所述适配器发送第三电压控制信号，控制所述适配器按照设定的第二电压增值增大输出电压以使所述上电的快充充电电路的第二电流值增大，其中，所述第二电压增值小于所述第一电压增值，所述第二电流值大于所述第一电流值。
因为对电池快充时的额定电流是一定的，当对电池的充电电流达到额定电流时，需要停止充电电流的增大，即控制适配器停止增大输出电压，防止对电池充电的电流过大造成电池的损坏。所述控制所述适配器按照设定的第二电压增值增大输出电压之后，所述方法还包括：
获取流经所述上电的快充充电电路的第二电流值；
如果所述第二电流值达到预设的第二电流阈值，向所述适配器发送第四电压控制信号，控制所述适配器输出第二固定电压以使所述电池两端的第一电压值增大，其中所述第二电流阈值大于所述第一电流阈值，所述第二固定电压大于所述第一固定电压。
具体的，第二电流阈值可以是其对应的额定电流值，当判断第二电流值达到预设的第二电流阈值时，则说明对电池充电的电流达到对电池充电的额定电流，向适配器发送第四电压控制信号，控制所述适配器输出第二固定电压，对电池进行充电。此时适配器以第二固定电压向电池充电，在不断充电的过程中，电池两端输出的第一电压值不断增大。
