本申请要求在2022年01月29日提交中国专利局、申请号为202210114021.0、名称为“电子设备及控制方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及电子设备技术领域，具体涉及一种电子设备及控制方法。
背景技术
随着科技的发展，电子设备的应用越来越广泛。通常电子设备包括第一壳体和第二壳体，第一壳体与第二壳体活动连接，从而使得电子设备可以折叠或展开。电子设备中通常设置电池组件。在对电子设备充电的过程中，电子设备中的充电回路的散热较大。
申请内容
本申请实施例提供了一种电子设备及控制方法，以解决相关技术中对电子设备充电的过程中，电子设备中的充电回路的散热较大的问题。
第一方面，本申请实施例提供了一种电子设备，所述电子设备包括：第一壳体、第二壳体、第一电池组件、第二电池组件、充电管理模块；
所述第一壳体与所述第二壳体活动连接，以使所述第一壳体与所述第二壳体具有叠置状态和展开状态；
所述第一电池组件位于所述第一壳体中，所述第二电池组件位于所述第二壳体中，所述充电管理模块位于所述第一壳体或所述第二壳体中；
所述充电管理模块与所述第一电池组件的正极电连接，所述第一电池组件的负极与所述第二电池组件的正极电连接，所述第二电池组件的负极接地。
第二方面，本申请实施例提供了一种控制方法，应用于上述第一方面中所述的电子设备中，所述方法包括
获取所述第一电池组件的电量以及所述第二电池组件的电量；
在所述第一电池组件的电量大于或等于所述第二电池组件的电量的情况下，调整所述第一电池组件以及所述第二电池组件的电量，以使所述第一电池组件的电量等于所述第二电池组件的电量，或，所述第一电池组件的电量与所述第二电池组件的电量之间的差值小于预设电量阈值；
在所述第二电池组件的电量大于或等于所述第一电池组件的电量的情况下，调整所述第一电池组件以及所述第二电池组件的电量，以使所述第一电池组件的电量等于所述第二电池组件的电量，或，所述第一电池组件的电量与所述第二电池组件的电量之间的差值小于预设电量阈值。
在本申请实施例中，由于第一壳体与第二壳体活动连接，因此，第一壳体与第二壳体可以相互靠近或者相互远离，从而使得电子设备叠置或者展开。由于第一电池组件位于第一壳体中，第二电池组件位于第二壳体中，因此，第一电池组件可以向第一壳体中的器件提供电能，第二电池组件可以向第二壳体中的器件提供电能。由于充电管理模块与第一电池组件的正极电连接，因此，通过充电管理模块可以向第一电池组件充电。由于第一电池组件的负极与第二电池组件的正极电连接，第二电池组件的负极接地，因此，第一电池组件与第二电池组件相当于串联，从而在通过充电管理模块向第一电池组件充电时，第一电池组件可以将电能传递至第二电池组件，从而通过充电管理模块可以向第一电池组件与第二电池组件充电。另外，由于第一电池组件与第二电池组件串联，因此，充电回路中的阻抗增加，从而使得充电回路中的电流降低，使得充电回路中的散热减小。也即是，在本申请实施例中，通过将第一电池组件与第二电池组件串联，可以使得在对电子设备充电时，充电回路的散热减小。

具体实施例
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。
应理解，说明书通篇中提到的“一个实施例”或“一实施例”意味着与实施例有关的特定特征、结构或特性包括在本申请的至少一个实施例中。因此，在整个说明书各处出现的“在一个实施例中”或“在一实施例中”未必一定指相同的实施例。此外，这些特定的特征、结构或特性可以任意适合的方式结合在一个或多个实施例中。
参照图1，示出了本申请实施例提供的一种电子设备的示意图；参照图2，示出了本申请实施例提供的一种电子设备的原理图。如图1和图2所示，该电子设备包括：第一壳体10、第二壳体20、第一电池组件30、第二电池组件40、充电管理模块50。
第一壳体10与第二壳体20活动连接，以使第一壳体与第二壳体具有叠置状态和展开状态。第一电池组件30位于第一壳体10中，第二电池组件40位于第二壳体20中，充电管理模块50位于第一壳体10或第二壳体20中。充电管理模块50与第一电池组件30的正极电连接，第一电池组件30的负极与第二电池组件40的正极电连接，第二电池组件40的负极接地。
在本申请实施例中，由于第一壳体10与第二壳体20活动连接，因此，第一壳体10与第二壳体20可以相互靠近或者相互远离，从而使得电子设备叠置或者展开。由于第一电池组件30位于第一壳体10中，第二电池组件40 位于第二壳体20中，因此，第一电池组件30可以向第一壳体10中的器件提供电能，第二电池组件40可以向第二壳体20中的器件提供电能。由于充电管理模块50与第一电池组件30的正极电连接，因此，通过充电管理模块50可以向第一电池组件30充电。由于第一电池组件30的负极与第二电池组件40的正极电连接，第二电池组件40的负极接地，因此，第一电池组件30与第二电池组件40相当于串联，从而在通过充电管理模块50向第一电池组件30充电时，第一电池组件30可以将电能传递至第二电池组件40，从而通过充电管理模块50可以向第一电池组件30与第二电池组件40充电。另外，由于第一电池组件30与第二电池组件40串联，因此，充电回路中的阻抗增加，从而使得充电回路中的电流降低，使得充电回路中的散热减小。也即是，在本申请实施例中，通过将第一电池组件30与第二电池组件40串联，可以使得在对电子设备充电时，充电回路的散热减小。
在相关技术中，电子设备包括第一壳体10、第二壳体20、第一电池组件30以及第二电池组件40，第一电池组件30与第二电池组件40分别位于第一壳体10和第二壳体20中，第一电池组件30与第二电池组件40并联，从而充电回路中的阻抗较小，使得充电回路中的电流较大，而充电回路中的散发的热量为充电回路中的电流的平方与阻挡的乘积，使得在对电子设备充电时，充电回路散发的热量较大。
而在本申请实施例中，将第一电池组件30的正极与充电管理模块50电连接，第一电池组件30的负极与第二电池组件40的正极电连接，相当于第一电池组件30与第二电池组件40串联，从而使得在使用相同功率的充电器对电子设备充电时，充电回路中的电流减小，使得充电回路的散热减小。
例如，通过40W的充电器对电子设备充电，在相关技术中，第一电池组件30与第二电池组件40并联，充电回路中的阻抗较小，电流较大，电流可能是10A，从而充电回路散热较大。而在本申请中，第一电池组件30与第二电池组件40串联，充电回路中的阻抗较大，电流较小，电流可能是5A，从而充电回路散热较小。
另外，在一些实施例中，电子设备还可以包括第一分流器60、第二分流器70、第一控制开关80以及第二控制开关90。第一分流器60位于第一壳体10或第二壳体20中，第二分流器70位于第一壳体10或第二壳体20中，第一控制开关80位于第一壳体10或第二壳体20中，第二控制开关90位于第一壳体10或第二壳体20中。第一分流器60的第一端与第一电池组件30的正极电连接，第一分流器60的第二端与第一控制开关80的第一端电连接，第一控制开关80的第二端分别与第二控制开关90的第一端、第二分流器70的第一端电连接，第二分流器70的第二端与第二电池组件40的正极电连接，第二控制开关90的第二端与第二电池组件40的负极电连接。在第一电池组件30的电量大于第二电池组件40的电量的情况下，第一控制开关80处于导通状态，第二控制开关90处于断开状态；在第二电池组件40的电量大于第一电池组件30的电量的情况下，第一控制开关80处于断开状态，第二控制开关90处于导通状态。
由于第一分流器60的第一端与第一电池组件30的正极电连接，第一分流器60的第二端与第一控制开关80的第一端电连接，第一控制开关80的第二端分别与第二控制开关90的第一端、第二分流器70的第一端电连接，第二分流器70的第二端与第二电池组件的正极电连接，因此，在第一控制开关80处于导通状态时，此时，相当于第一分流器60与第二分流器70串联，且第一分流器60与第二分流器70均与第一电池组件30并联，从而在第一电池组件30的正极输入电流之后，第一分流器60以及第二分流器70会分走输入第一电池组件30的部分电流。由于第二分流器70第二端与第二电池组件40的正极电连接，第二控制开关90的第一端与第一控制开关80的第二端电连接，第二分流器70的第一端与第一控制开关80的第二端电连接，第二控制开关90的第二端与第二电池组件40的负极电连接，因此，在第二控制开关90处于导通状态时，此时，相当于第二分流器70与第二电池组件40并联，从而在第二电池组件40正极输入电流之后，第二分流器70会分走输入第二电池组件40的部分电流。
另外，由于第一电池组件30与第二电池组件40相当于串联，因此，可能由于第一电池组件30与第二电池组件40在制造上的差异，或者随着第一电池组件30与第二电池组件40使用之后，在对电子设备充电时，即第一对电池组件与第二电池组件40充电，第一电池组件30与第二电池组件40的电池容量不同，从而使得第一电池组件30上的电量与第二电池组件40上的电量不同，影响电子设备的使用。为了避免这种问题，在本申请实施例中，在对电子设备充电的过程中，在第一电池组件30的电量大于第二电池组件40的电量的情况下，可以使得第一控制开关80处于导通状态，第二控制开关90处于断开状态，从而相当于第一分流器60与第二分流器70串联，且第一分流器60与第二分流器70串联之后与第一电池组件30并联，第一分流器60与第二分流器70会分走输入第一电池组件30的正极中的电流。但第一电池组件30与第二电池组件40串联，相当于第一分流器60与第二分流器70串联之后与第一电池组件30并联，之后在与第二电池组件40串联，因此，输入第二电池组件40的中的电流为第一电池组件30上的电流与第一分流器60上的电流之和，从而第一电池组件30上的电流小于第二电池组件40上的电流，使得在充电的过程中，向第一电池组件30充的电量较少，向第二电池组件40充的电量较多，从而在充电之后，或者在充电的过程中，第一电池组件30中的电量与第二电池组件40中的电量相等。
在第二电池组件40的电量大于第一电池组件30的电量的情况下，可以使得第一控制开关80处于断开状态，第二控制开关90处于导通状态，从而相当于第二分流器70与第二电池组件40并联。但第一电池组件30与第二电池组件40串联，相当于第二电池组件40与第二分流器70并联之后与第一电池组件30串联，从而从第一电池组件30输出的电流流入第二电池组件40之后，该电流会被第二分流器70分走部分，从而第二电池组件40上的电流小于第一电池组件30上的电流，使得在充电的过程中，向第一电池组件30充的电量较多，向第二电池组件40充的电量较少，从而在充电之后，或者在充电的过程中，第一电池组件30中的电量与第二电池组件40中的电量 相等。
例如，如图2所示，在对电子设备充电的过程中，若从充电管理模块50流出的电流大小为I，在第一电池组件30的电量大于第二电池组件40的电量的情况下，第一控制开关80处于导通状态，第二控制开关90处于断开状态，电流的流向如图2中A所指的电流路径，此时，第一分流器60与第二分流器70串联，之后与第一电池组件30并联，且流经第一分流器60的电流为I1，则流入第一电池组件30中的电流为I-I1，流入第二电池组件40中的电流为I，从而流入第二电池组件40中的电流I大于流入第一电池组件30中的电流I-I1，之后可以持续保持第一控制开关80处于导通状态，第二控制开关90处于断开状态，从而在对电子设备充电之后，或者在对电子设备充电的过程中，使得第一电池组件30上的电量等于第二电池组件40上的电量。
同理，在第二电池组件40的电量大于第一电池组件30的电量的情况下，第一控制开关80处于断开状态，第二控制开关90处于导通状态，电流的流向如图2中B所指的电流路径，此时，第二分流器70与第二电池组件40并联，且流经第二分流器70的电流为I2，则流入第二电池组件40中的电流为I-I2，从而流入第一电池组件30中的电流I大于流入第二电池组件40中的电流I-I2，之后可以持续保持第一控制开关80处于断开状态，第二控制开关90处于导通状态，从而在对电子设备充电之后，或者在对电子设备充电的过程中，使得第一电池组件30上的电量等于第二电池组件40上的电量。
需要说明的是，I1与I2的大小可以相等，当然I1与I2的大小也可以不相等。另外，可以通过调整第一分流器60的阻抗，从而确定流经第一分流器60的电流的大小，同理，也可以通过调整第二分流器70的阻抗，从而确定流经第二分流器70的电流的大小。
另外，在一些实施例中，在第一电池组件30的电量大于第二电池组件40的电量，且第一电池组件30的电量与第二电池组件40的之间的差值大于预设电量阈值的情况下，第一控制开关80处于导通状态，第二控制开关90处于断开状态，以使第一电池组件30的电量与第二电池组件40的电量之间 的差值小于或等于预设电量阈值；在第二电池组件40的电量大于第一电池组件30的电量，且第二电池组件40的电量与第一电池组件30的之间的差值大于预设电量阈值的情况下，第一控制开关80处于断开状态，第二控制开关90处于导通状态，以使第二电池组件40的电量与第一电池组件30的电量之间的差值小于或等于预设电量阈值。
在第一电池组件30的电量大于第二电池组件40的电量，且第一电池组件30的电量与第二电池组件40的之间的差值大于或等于预设电量阈值的情况下，可以使得第一控制开关80处于导通状态，第二控制开关90处于断开状态，从而可以使得第一分流器60和第二分离器串联，之后与第一电池组件30并联，从而使得流经第一电池组件30的电流小于流经第二电池组件40的电流，从而可以使得在充电之后，或者在充电的过程中，第一电池组件30的电量与第二电池组件40的电量的差值小于预设电量阈值。在第二电池组件40的电量大于第一电池组件30的电量，且第二电池组件40的电量与第一电池组件30的之间的差值大于预设电量阈值的情况下，可以使得第一控制开关80处于断开状态，第二控制开关90处于导通状态，从而可以使得第二分流器70与第二电池组件40并联，从而使得流经第一电池组件30的电流大于流经第二电池组件40的电流，从而可以使得在充电之后，或者在充电的过程中，第一电池组件30的电量与第二电池组件40的电量的差值小于或等于预设电量阈值。
需要说明的是，预设电量阈值可以根据实际需要进行设定，例如，预设电量阈值可以为20mv，当然，预设电量阈值还可以为其他数值，对此，本申请实施例在此不做限定。
另外，由于电量等于电流与时间的乘积，因此，在确定了电流以及电量之后，便可以确定时间，从而可以确定控制第一控制开关80以及第二控制开关90的时间。
例如，充电管理模块50输出的电流为I，若第一电池组件30的电量大于第二电池组件40的电量，第一分流器60与第二分流器70串联，之后与 第一电池组件30并联，流经第一分流器60的电流为I1，流经第一电池组件30上的电流为I-I1，第二电池组件40上的电流为I，在同样的时间t内，充入第二电池组件40上的电量会比充入第一电池组件30上的电量多I1*t。若第一电池组件30的电量与第二电池组件40的电量之间的差值为Z，且Z大于或等于预设电量阈值，预设电量阈值为X，在充电的过程中，需要至少控制第一控制开关80以及第二控制开关90的时间为(Z-X)/I1，即需要控制第一控制开关80处于导通状态，第二控制开关90处于断开状态的时间为(Z-X)/I1，可以使得第一电池组件30上的电量与第二电池组件40上的电量之间的差值小于或等于预设电量阈值。再例如，第一电池组件30的电量与第二电池组件40的电量之间的差值为30，预设电量阈值为20，I1为0.05，则在充电的过程中，需要至少控制第一控制开关80以及第二控制开关90的时间为(30-20)/0.05，即需要控制第一控制开关80处于导通状态，第二控制开关90处于断开状态的时间为(30-20)/0.05。
同理，若第二电池组件40的电量大于第一电池组件30的电量，第二分流器70与第二电池组件40并联，流经第二分流器70的电流为I2，流经第二电池组件40上的电流为I-I2，第一电池组件30上的电流为I，在同样的时间t内，充入第一电池组件30上的电量会比充入第二电池组件40上的电量多I2*t。若第二电池组件40的电量与第一电池组件30的电量之间的差值为Z，且Z大于或等于预设电量阈值，预设电量阈值为X，在充电的过程中，需要至少控制第一控制开关80以及第二控制开关90的时间为(Z-X)/I2，即需要控制第一控制开关80处于断开状态，第二控制开关90处于导通状态的时间为(Z-X)/I2，可以使得第一电池组件30上的电量与第二电池组件40上的电量之间的差值小于或等于预设电量阈值。再例如，第二电池组件40的电量与第一电池组件30的电量之间的差值为30，预设电量阈值为20，I1为0.05，则在充电的过程中，需要至少控制第一控制开关80以及第二控制开关90的时间为(30-20)/0.05，即需要控制第一控制开关80处于断开状态，第二控制开关90处于导通状态的时间为(30-20)/0.05。
另外，在一些实施例中，电子设备还可以包括控制器100以及电量计110。控制器100位于第一壳体10或第二壳体20中，电量计110位于第一壳体10或第二壳体20中。电量计110的电量采集端分别与第一电池组件30的正极、第二电池组件40的正极电连接，电量计110的输出端与控制器100电连接，电量计110的接地端接地，控制器100分别与第一控制开关80的控制端、第二控制开关90的控制端电连接。电量计110用于采集第一电池组件30的电量以及第二电池组件40的电量，控制器100用于接收第一电池组件30的电量以及第二电池组件40的电量，并在第一电池组件30的电量大于第二电池组件40的电量的情况下，控制第一控制开关80处于导通状态，第二控制开关90处于断开状态；在第二电池组件40的电量大于第一电池组件30的电量的情况下，控制第一控制开关80处于断开状态，第二控制开关90处于导通状态，以使第二电池组件40的电量与第一电池组件30的电量之间的差值小于预设电量阈值。
由于电量计110的电量采集端分别与第一电池组件30的正极、第二电池组件40的正极电连接，电量计110的输出端与控制器100电连接，因此，电量计110可以采集到第一电池组件30与第二电池组件40的电量，并将第一电池组件30的电量以及第二电池组件40的电量发送至控制器100。由于控制器100分别与第一控制开关80的控制端、第二控制开关90的控制端电连接，因此，控制器100在接收到第一电池组件30的电量以及第二电池组件40的电量之后，控制器100便可以确定第一电池组件30的电量与第二电池组件40的电量的大小，从而根据第一电池组件30的电量与第二电池组件40的电量的大小对第一控制开关80以及第二控制开关90进行控制。具体的，在第一电池组件30的电量大于第二电池组件40的电量的情况下，控制第一控制开关80处于导通状态，第二控制开关90处于断开状态；在第二电池组件40的电量大于第一电池组件30的电量的情况下，控制第一控制开关80处于断开状态，第二控制开关90处于导通状态，以使第二电池组件40的电量与第一电池组件30的电量之间的差值小于预设电量阈值。
另外，通过设置电量计110，还可以便于控制器100获取第一电池组件30与第二电池组件40的电量，从而便于控制器100根据第一电池组件30的电量以及第二电池组件40的电量，对第一控制开关80以及第二控制开关90进行控制。另外，设置控制器100，还可以便于控制第一控制开关80以及第二控制开关90。
另外，在一些实施例中，电子设备还可以包括控制模块120，控制模块120的接收端与控制器100电连接，且控制模块120的控制端分别与第一控制开关80的控制端、第二控制开关90的控制端电连接，控制模块120的接地端接地。
当控制模块120的接收端与控制器100电连接，控制模块120的控制端分别与第一控制开关80的控制端，第二控制开关90的控制端电连接时，此时，控制模块120的接收端可以接收到控制器100发送的控制指令，从而控制模块120可以根据控制指令控制第一控制开关80处于导通状态，第二控制开关90处于断开状态，或者控制第一控制开关80处于断开状态，第二控制开关90处于导通状态。也即是，通过设置控制模块120，可以便于控制器100对第一控制开关80以及第二控制开关90进行控制。
另外，在一些实施例中，电子设备还可以包括转轴组件130。第一壳体10以及第二壳体20通过转轴组件130活动连接。
当第一壳体10以及第二壳体20通过转轴组件130活动连接时，此时，在第一壳体10与第二壳体20相互远离，或者第一壳体10远离第二壳体20时，转轴组件130会相对转动，从而使得第一壳体10与第二壳体20可以相互远离，或者第一壳体10远离第二壳体20。
需要说明的是，第一壳体10与第二壳体20活动连接的方式还可以为：第一壳体10与第二壳体20通过铰链组件活动连接。或第一壳体10与第二壳体20通过滑动组件，实现两者的重叠或展开。
另外，在一些实施例中，电子设备还可以包括第一电路板140和第二电路板150。第一电路板140位于第一壳体10中，第二电路板150位于第二壳 体20中，第一电池组件30的负极与第一电路板140电连接，第一电路板140与第二电路板150电连接，第二电路板150与第二电池组件40的正极电连接。
当第一电池组件30的负极与第一电路板140电连接，第一电路板140与第二电路板150电连接，第二电路板150与第二电池组件40的正极电连接时，此时，在第一电池组件30的正极受到充电管理模块50的电流之后，第一电池组件30的负极可以将电流传递至第一电路板140，从而第一电路板140可以将电流传递至第二电路板150，第二电路板150将电流传递至第二电池组件40的正极，从而使得第一电池组件30的负极与第二电池组件40的正极电连接，使得第一电池组件30与第二电池组件40实现串联。另外，通过设置第一电路板140以及第二电路板150，直接将第一电池组件30与第一电路板140电连接，将第二电池组件40与第二电路板150电连接，之后将第一电路板140与第二电路板150电连接，从而可以便于第一电池组件30与第二电池组件40串联。
需要说明的是，在本申请实施例中，第一电路板140与第二电路板150均可以为印制电路板(Printed Circuit Board，PCB)，当然，第一电路板140与第二电路板150还均可以为柔性电路板(Flexible Printed Circuit，FPC)，对此，本申请实施例在此不作限定。
另外，在一些实施例中，电子设备还可以包括导电连接件160。导电连接件160的一端与第一电路板140电连接，导电连接件160的另一端与第二电路板150电连接。
当导电连接件160的一端与第一电路板140电连接，导电连接件160的另一端与第二电路板150电连接时，此时，在第一电池组件30接收到充电管理模块50传递的电流之后，第一电池组件30将电流传递至第一电路板140，第一电路板140将电流传递至导电连接件160，导电连接件160将电流传递至第二电路板150，第二电路板150将电流传递至第二电池组件40的正极，从而实现第一电池组件30与第二电池组件40的串联。另外，通过设置 导电连接件160，可以便于第一电路板140与第二电路板150电连接，从而便于第一电池组件30与第二电池组件40串联。
需要明的是，在本申请实施例中，导电连接件160可以为柔性电路板(Flexible Printed Circuit，PFC)，当然，导电连接件160还可以为其他可以导电的器件，比如导线，对于导电连接件160的具体类型，本申请实施例在此不做限定。
另外，在一些实施例中，第一控制开以及第二控制开关90均可以为MOS管。
当第一控制开关80以及第二控制开关90均为MOS管时，此时，由于MOS管便于控制，从而可以使得控制器100便于对第一控制开关80以及第二控制开关90进行控制，使得第一控制开关80导通或断开，或者使得第二控制开关90导通或断开。
需要说明的是，当第一控制开关80以及第二控制开关90均为MOS管时，此时，第一控制开关80的第一端可以为MOS管的源极，第一控制开关80的第二端可以为MOS管的漏极，第一控制开关80的控制端可以为MOS管的栅极；第二控制开关90的第一端可以为MOS管的源极，第二控制开关90的第二端可以为MOS管的漏极，第二控制开关90的控制端可以为MOS管的栅极。
当然，第一控制开关80以及第二控制开关90还可以为其他具有导通与关断功能的开关，例如，第一控制开关80以及第二控制开关90还可以为继电器、三极管等，对于第一控制开关80以及第二控制开关90的具体类型，本申请实施例在此不作限定。
还需要说明的是，在本申请实施例中，电子设备包括但不限于手机、笔记本电脑等。
在本申请实施例中，由于第一壳体10与第二壳体20活动连接，因此，第一壳体10与第二壳体20可以相互靠近或者相互远离，从而使得电子设备叠置或者展开。由于第一电池组件30位于第一壳体10中，第二电池组件40 位于第二壳体20中，因此，第一电池组件30可以向第一壳体10中的器件提供电能，第二电池组件40可以向第二壳体20中的器件提供电能。由于充电管理模块50与第一电池组件30的正极电连接，因此，通过充电管理模块50可以向第一电池组件30充电。由于第一电池组件30的负极与第二电池组件40的正极电连接，第二电池组件40的负极接地，因此，第一电池组件30与第二电池组件40相当于串联，从而在通过充电管理模块50向第一电池组件30充电时，第一电池组件30可以将电能传递至第二电池组件40，从而通过充电管理模块50可以向第一电池组件30与第二电池组件40充电。另外，由于第一电池组件30与第二电池组件40串联，因此，充电回路中的阻抗增加，从而使得充电回路中的电流降低，使得充电回路中的散热减小。也即是，在本申请实施例中，通过将第一电池组件30与第二电池组件40串联，可以使得在对电子设备充电时，充电回路的散热减小。
参照图3，示出了本申请实施例提供的一种控制方法的流程图，该控制方法应用于上述实施例中任一实施例中的电子设备中，如图3所示，该方法包括：
步骤301：获取第一电池组件的电量以及第二电池组件的电量。
当电子设备包括电量计时，电量计便可以直接测量第一电池组件的电量以及第二电池组件的电量，从而电量计将第一电池组件的电量以及第二电池组件的电量发送至控制器，控制器便可以获取第一电池组件的电量以及第二电池组件的电量。
步骤302：在第一电池组件的电量大于第二电池组件的电量的情况下，调整第一电池组件以及第二电池组件的电量，以使第一电池组件的电量等于第二电池组件的电量，或，第一电池组件的电量与第二电池组件的电量之间的差值小于或等于预设电量阈值。
当第一电池组件的电量大于第二电池组件的电量时，此时，控制器可以控制第一控制开关处于导通状态，第二控制开关处于断开状态，且控制时间 达到一定时间之后，第一电池组件的电量等于第二电池组件的电量，或，第一电池组件的电量与第二电池组件的电量之间的差值小于或等于预设电量阈值。
步骤303：在第二电池组件的电量大于第一电池组件的电量的情况下，调整第一电池组件以及第二电池组件的电量，以使第二电池组件的电量等于第一电池组件的电量，或，第二电池组件的电量与第一电池组件的电量之间的差值小于或等于预设电量阈值。
当第二电池组件的电量大于第一电池组件的电量时，此时，控制器可以控制第一控制开关处于断开状态，第二控制开关处于导通状态，且控制时间达到一定时间之后，第一电池组件的电量等于第二电池组件的电量，或，第二电池组件的电量与第一电池组件的电量之间的差值小于或等于预设电量阈值。
