请参考图1，其示出了本发明各个实施例提供的充电方法所涉及的实施环境的结构示意图。该实施环境包括主设备120、从设备140和连接线160。
主设备120和从设备140是具有多功能I/O接口的电子设备，该电子设备可以为智能手机、平板电脑、电子书阅读器、MP3播放器(Moving Picture Experts Group Audio LayerⅢ，动态影像压缩标准音频层面3)、MP4(Moving Picture Experts Group Audio LayerⅣ，动态影像压缩标准音频层面4)播放器或膝上型便携计算机等等。通常情况下，主设备120和从设备140上的多功能I/O接口相同，且该多功能I/O接口能够实现主设备和从设备的转换。比如，该多功能I/O接口可以为Type C接口。

在步骤201中，接收设置信号，根据设置信号确定充电方向；
在步骤202中，当充电方向为第一充电方向时，确定充电操作为由主设备向从设备充电；
在步骤203中，当充电方向为第二充电方向时，确定充电操作为由从设备向主设备充电；
在步骤204中，根据充电操作，向主设备的电源管理芯片和从设备的电源管理芯片发送相应的充电指令。
综上所述，本实施例提供的充电方法，通过主设备根据设置的充电方向，向主设备和从设备的电源管理芯片发送相应的充电指令，从而实现为从设备充电或由从设备为主设备充电；解决了使用移动电源为智能设备充电，由于移动电源体积较大，不利于用户携带的问题；达到了通过连接线连接的两个智能设备，即能够根据用户设置的充电方向，实现智能设备之间相互充电的效果。
为了使用户能够更加直观了解到主设备和从设备的剩余电量，并根据该剩余电量设置充电方向，主设备可以以进度条的形式对主设备和从设备的剩余电量进行显示，并通过该进度条接收用户设置的目标剩余电量，作为一种可能的实施方式，如图2B所示，上述步骤201，可以包括如下步骤：
在步骤201A中，通过电量控制进度条显示初始电量信息，初始电量信息包含主设备初始剩余电量和从设备初始剩余电量分别占剩余总电量的百分比；剩余总电量为主设备初始剩余电量与从设备初始剩余电量之和；
在步骤201B中，接收对电量控制进度条的滑动操作；
在步骤201C中，根据滑动操作确定目标电量信息；目标电量信息包含主设备目标剩余电量和从设备目标剩余电量分别占剩余总电量的百分比；
在步骤201D中，根据初始电量信息和目标电量信息确定充电方向。
为了使用户实时了解到主设备和从设备之间的充电情况，主设备可以每隔预定时间间隔获取主设备和从设备的当前剩余电量，并根据当前剩余电量信息对进度条进行更新，作为一种可能的实施方式，如图2C所示，该方法，还可以包括：
在步骤205中，每隔预定时间间隔获取第一电量消耗信息和主设备当前剩余电量；第一电量消耗信息用于指示主设备在充电期间的耗电情况；
在步骤206中，每隔预定时间间隔通过连接线建立的连接，从从设备中读取第二电量消耗信息和从设备当前剩余电量；第二电量消耗信息用于指示从设备在充电期间的耗电情况；
在步骤207中，根据主设备当前剩余电量、从设备当前剩余电量、第一电量消耗信息和第二电量消耗信息分别占剩余总电量的百分比，更新电量控制进度条。
图3是根据另一示例性实施例示出的充电方法的方法流程图。本实施例以该充电方法用于图1所示实施环境中的从设备140为例进行说明，该方法包括：
在步骤301中，接收主设备向从设备的电源管理芯片发送的充电指令；充电指令主设备根据用户设置的充电方向确定的充电操作生成的；
在步骤302中，根据充电指令，通过连接线和电源管理芯片，与主设备完成充电操作。
综上所述，本实施例提供的充电方法，通过从设备接收主设备向从设备电源管理芯片发送的充电指令，并根据该充电指令与主设备完成充电操作；解决了使用移动电源为智能设备充电，由于移动电源体积较大，不利于用户携带的问题；达到了通过连接线连接的两个智能设备，即能够根据用户设置的充电方向，实现智能设备之间相互充电的效果。
图4A是根据再一示例性实施例示出的充电方法的方法流程图。本实施例以该充电方法用于图1所示实施环境来进行说明，该方法包括：
在步骤401中，主设备通过电量控制进度条显示初始电量信息。
用户使用连接线连接两个智能设备时，即在两个智能设备之间建立了数据通信连接，智能设备之间可以通过该连接线进行数据的传输。比如，该连接线可以为Type C连接线，Type C连接线的两端均为Type C接头，且两个智能设备的多功能I/O接口均为Type C接口，使用该Type C连接线即可在两个智能设备之间建立连接。需要说明的是，具有Type C接口的两个智能设备采用Type C协议。
通过该Type C连接线连接的两个智能设备中，其中一个智能设备为主设备，另一个智能设备为从设备，主设备可以向从设备中读写数据，但是从设备不能主设备中读写数据。作为一种可能的实施方式，两个智能设备中，首先插入Type C连接线的智能设备被设置为默认的主设备，相应的，后插入Type C连接线的智能设备被设置为默认从设备。并且，智能设备建立连接后，主设备(或从设备)可以向从设备(或主设备)发送主设备切换请求，从设备(或主设备)则根据该主设备切换请求切换为主设备(或从设备)，并根据当前的主从设备关系建立新的数据通信。通过Type C协议实现主从设备的自由切换为本领域技术人员所熟知，在此不再赘述。
为了使用户能够知悉智能设备当前的剩余电量，并根据该剩余电量设置充电方向，主 设备可以以电量控制进度条初始电量信息进行显示，该初始电量信息包含主设备初始剩余电量和从设备初始剩余电量分别占剩余总电量的百分比；剩余总电量为主设备初始剩余电量与从设备初始剩余电量之和。
作为一种可能的实施方式，如图4B所示，本步骤可以包括如下步骤：
在步骤401A中，主设备获取主设备初始剩余电量。
用户使用Type C连接线将两个智能设备连接时，两个智能设备中的主设备可以自动调用预定应用程序，该预定应用程序用于控制智能设备之间进行充电操作。
启动该预定应用程序后，主设备可以调用相应的进程获取主设备当前剩余电量，并将当前剩余电量确定为主设备初始剩余电量。
在步骤401B中，主设备通过连接线建立的连接读取从设备对应的从设备初始剩余电量。
由于主设备能够从从设备中读写数据，所以主设备在获取自身剩余电量的同时，可以通过Type C连接线读取从设备当前剩余电量，并将读取到的当前剩余电量确定为从设备初始剩余电量。
在步骤401C中，主设备根据主设备初始剩余电量和从设备初始剩余电量分别占剩余总电量的百分比，确定主设备初始剩余电量对应的进度条和从设备初始剩余电量对应的进度条分别占电量控制进度条的长度百分比。
主设备根据获取到的主设备初始剩余电量和从设备初始剩余电量，计算得到剩余电量。且为了使用户更加直观了解到主设备和从设备剩余电量的大小关系，主设备进一步计算主设备初始剩余电量和从设备初始剩余电量分别占剩余总电量的百分比。
计算得到主设备初始剩余电量和从设备初始剩余电量分别占剩余总电量的百分比后，主设备即在屏幕上显示电量控制进度条。其中，主设备初始剩余电量对应的进度条占电量控制进度条的长度百分比即主设备初始剩余电量占剩余总电量的百分比；从设备初始剩余电量对应的进度条占电量控制进度条的长度百分比即从设备初始剩余电量占剩余总电量的百分比。需要说明的，主设备初始剩余电量对应的进度条和从设备初始剩余电量对应的进度条采用不同的背景色进行标识，方便用户区分。
比如，如图4C所示，主设备41获取到主设备初始剩余电量为1000毫安时，并通过连接线读取到从设备42的从设备初始剩余电量为500毫安时，计算得到主设备初始剩余电量和从设备初始剩余电量分别占剩余总电量的百分比分别为67％和33％。根据计算得到的百分比，主设备41显示电量控制进度条43，其中，主设备初始剩余电量对应的进度条431占电量控制进度条43的长度百分比为67％，从设备初始剩余电量对应的进度条432占电量控制进度条43的长度百分比为33％。
在步骤402中，主设备接收对电量控制进度条的滑动操作。
主设备显示电量控制进度条后，通过用户对该电量控制进度条的滑动操作，确定用户设置的目标电量信息。其中，该滑动操作可以指拖动电量控制进度条上的滑动杆。需要说 明的是，主设备接收对电量控制进度条的滑动操作的同时，需要根据滑动杆的实时位置更新电量控制进度条上显示的数值信息。
比如，如图4C所示，主设备41通过电量控制进度条43上的滑动杆433接收用户的滑动操作，并根据滑动操作更新进度条431和进度条432中显示的百分数值。
在步骤403中，主设备根据滑动操作确定目标电量信息；目标电量信息包含主设备目标剩余电量和从设备目标剩余电量分别占剩余总电量的百分比。
主设备根据该滑动操作确定用户设置的主设备目标剩余电量和从设备目标剩余电量分别占剩余总电量的百分比。
比如，如图4D所示，滑动杆433被拖动至图示位置，当用户点击确定按钮44时，主设备41即根据当前滑动杆433在电量控制进度条43上所处的位置，确定用户设置的主设备目标剩余电量和从设备目标剩余电量占剩余总电量的百分比分别为33％和67％。
在步骤404中，主设备根据初始电量信息和目标电量信息确定充电方向。
由于可以由主设备向从设备充电，也可以由从设备向主设备充电，主设备需要根据初始电量信息及用户设置的目标电量信息进一步确定充电方向。
作为一种可能的实施方式，本步骤可以包括如下步骤：
在步骤404A中，当主设备目标剩余电量占剩余总电量的百分比小于主设备初始剩余电量占剩余总电量的百分比时，或，当从设备目标剩余电量占剩余总电量的百分比大于从设备初始剩余电量占剩余总电量的百分比时，主设备确定充电方向为第一充电方向。
其中，第一充电方向指由主设备为从设备充电。
当充电方向为第一充电方向时，执行步骤405。
比如，如图4D所示，主设备目标剩余电量占剩余总电量的百分比为33％，小于主设备初始剩余电量占剩余总电量的百分比67％，主设备41即确定充电方向为第一充电方向，
在步骤404B中，当主设备目标剩余电量占剩余总电量的百分比大于主设备初始剩余电量占剩余总电量的百分比时，或，当从设备目标剩余电量占剩余总电量的百分比小于从设备初始剩余电量占剩余总电量的百分比时，主设备确定充电方向为第二充电方向。
其中，第二充电方向指由从设备为主设备充电。
当充电方向为第二充电方向时，执行步骤406。
在步骤405中，当充电方向为第一充电方向时，主设备确定充电操作为由主设备向从设备充电。
为了使用户更加直观了解到设置的充电方向，主设备确定充电方向后，还会显示相应的充电方向图标。
比如，如图4D所示，主设备41根据用户设置的充电方向显示相应的第一充电方向图标45。
在步骤406中，当充电方向为第二充电方向时，主设备确定充电操作为由从设备向主设备充电。
相应的，当主设备确定充电方向为第二充电方向时，显示相应的第二充电方向图标。
在步骤407中，主设备根据充电操作，向主设备的电源管理芯片和从设备的电源管理芯片发送相应的充电指令。
主设备根据确定的充电操作，向主设备的电源管理芯片和从设备的电源管理芯片发送相应的充电指令。
当充电操作指示由主设备向从设备充电时，主设备即向主设备的电源管理芯片发送指示主设备进行放电的指令，并通过Type C连接线向从设备的电源管理芯片发送指示从设备进行充电的指令；当充电操作指示由从设备向主设备充电时，主设备即向主设备的电源管理芯片发送指示主设备进行充电的指令，并通过Type C连接线向从设备的电源管理芯片发送指示从设备进行放电的指令。
在步骤408中，从设备接收主设备向从设备的电源管理芯片发送的充电指令。
对应的，从设备通过Type C连接线接收主设备发送的充电指令。
在步骤409中，从设备根据充电指令，通过连接线和电源管理芯片，与主设备完成充电操作。
当从设备接收到的指示其向主设备充电的充电指令时，从设备即通过Type C连接线向主设备进行充电；
当从设备接收到的主设备为从设备充电的充电指令时，从设备即通过Type C连接线接收主设备传输的电量资源。
在步骤410，主设备每隔预定时间间隔获取第一电量消耗信息和主设备当前剩余电量；第一电量消耗信息用于指示主设备在充电期间的耗电情况。
为了使用户能够了解到充电进程，主设备会每隔预定时间间隔获取主设备当前剩余电量，该预定时间间隔可以为10秒。
另外，主设备和从设备进行充电的过程中，由于程序运行和用户使用等原因，会不断耗电，为了使用户了解设备的耗电情况，主设备在获取主设备当前剩余电量的同时，还将获取用于指示主设备在充电期间耗电情况的第一电量消耗信息。
在步骤411中，主设备每隔预定时间间隔通过连接线建立的连接，从从设备中读取第二电量消耗信息和从设备当前剩余电量。
对应的，主设备在获取第一电量消耗信息和主设备当前剩余电量的同时，还需要通过Type C连接线读取从设备的第二电量消耗信息和从设备当前剩余电量，其中，第二电量消耗信息用于指示从设备在充电期间耗电情况。
在步骤412中，从设备每隔预定时间间隔，通过连接线建立的连接，向主设备中发送第二电量消耗信息和从设备当前剩余电量。
对应的，从设备通过Type C连接线将第二电量消耗信息和从设备当前剩余电量发送至主设备。
需要说明的是，主设备可以主动读取第二电量消耗信息和从设备当前剩余电量，也可 以接收从设备主动发送的第二电量消耗信息和从设备当前剩余电量，本公开并不对此进行限定。
在步骤413中，主设备根据主设备当前剩余电量、从设备当前剩余电量、第一电量消耗信息和第二电量消耗信息分别占剩余总电量的百分比，更新电量控制进度条。
主设备根据获取到主设备当前剩余电量、从设备当前剩余电量、第一电量消耗信息和第二电量消耗信息，对电量控制进度条中的数值进行实时更新。
其中，主设备通过电量控制进度条显示当前电量信息时，使用不同颜色对主设备当前剩余电量对应的进度条、从设备当前剩余电量对应的进度条、第一电量消耗信息对应的进度条和第二电量消耗信息对应的进度条进行标识。
比如，如图4D所示，主设备41对分别采用不同的背景颜色对主设备当前剩余电量、从设备当前剩余电量、第一电量消耗信息和第二电量消耗信息进行标识。
需要说明的一点是，主设备还可以根据用户设置的目标电量信息，在电量控制进度条上显示相应的目标电量提示标识，用于指示用户设置的目标电量。
需要说明的另一点是，主设备还可以根据当前剩余电量和目标剩余电量计算得到待充电量，并根据该待充电量和当前的充电速度计算得到剩余充电时间，并进行显示，方便用户把握充电的时间。
需要说明的是，为了保证充电效果，主设备获取到第一电量消耗信息和第二电量消耗信息后，计算充电期间主设备对应的第一耗电速度以及从设备对应的第二耗电速度，当第一耗电速度或第二耗电速度大于预设耗电阈值时，主设备即确定充电期间耗电过快，并发出相应的提示信息，提醒用户为了保证充电效果减少使用设备，或自动调用相应的程序，对预定程序进行清理，从而达到更好的充电效果。其中，预定程序可以为后台运行程序或使用频率较低程序。
在步骤414中，当主设备当前剩余电量达到主设备目标剩余电量，或从设备当前剩余电量达到从设备目标剩余电量时，主设备向主设备的电源管理芯片和从设备的电源管理芯片发送停止充电指令。
当主设备检测到当前剩余电量达到目标剩余电量时，自动向主设备的电源管理芯片和从设备的电源管理芯片发送停止充电指令，命令主设备和从设备之间停止充电操作。
在步骤415中，从设备接收主设备通过连接线建立的连接发送的停止充电指令。
该停止充电指令是主设备检测到主设备当前剩余电量达到主设备目标电量，或检测到从设备当前剩余电量达到从设备目标电量时发送的。
在步骤416中，从设备根据停止充电指令停止与主设备之间的充电操作。
对应的，从设备的电源管理芯片根据接收到的停止充电指令，停止与主设备之间的充电操作。
综上所述，本实施例提供的充电方法，通过主设备根据设置的充电方向，向主设备和从设备的电源管理芯片发送相应的充电指令，从而实现为从设备充电或由从设备为主设备 充电；解决了使用移动电源为智能设备充电，由于移动电源体积较大，不利于用户携带的问题；达到了通过连接线连接的两个智能设备，即能够根据用户设置的充电方向，实现智能设备之间相互充电的效果。
