下文中以应用在有线充电场景为例进行说明，当然在无线充电场景下，其实现原理和在有线充电场景下的实现原理类似。

应理解，图1的(a)中，以电子设备100和充电设备200通过有线的方式连接为例，实际上，电子设备100还可以通过无线的方式与充电设备200连接。充电设备200从家用电获取电能，然后将电能提供给电子设备100。
如图1的(b)所示，该场景中包括电子设备100(以手机为例)和充电设备200(以充电宝为例)为例。该场景中，手机与充电宝连接之后，充电宝将存储的电能提供给手机。
本申请实施例的技术方案可以适用于上述两种应用场景，或者其他的应用场景，本申请实施例不作限定。
本申请实施例中，电子设备可以是指向用户提供语音和/或数据连通性的设备，例如可以包括具有无线连接功能的手持式设备、或连接到无线调制解调器的终端设备。该终端设备可以经无线接入网(radio access network，RAN)与核心网进行通信，与RAN交换语音和/或数据。该终端设备可以包括用户设备(user equipment，UE)、无线终端设备、移动终端设备、订户单元(subscriber unit)、订户站(subscriber station)、移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点(access point，AP)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user agent)、或用户装备(user device)等。例如，可以包括移动电话(或称为“蜂窝”电话)、移动电脑、平板电脑、个人数字助理(personal digital assistant，PDA)、媒体播放器、智能电视、穿戴式设备(例如智能手表、智能头盔或智能手环等)、路由器，机顶盒，音箱，手机，平板等，以及上述两项或两项以上的组合等。电子设备还可以是车载系统，比如电动车等。
以下介绍图1所示的场景中的电子设备100、用于这样的电子设备的图形用户界面(graphical user interface，GUI)、和用于使用这样的电子设备的实施例。在本申请一些实施例中，电子设备100可以是包含内置电池的便捷式终端，诸如手机、平板电脑等，也可以是不包含内置电池的终端，本申请实施例不作限定。上述电子设备100的示例性实施例包括但不限于搭载iOS、Android、Microsoft或者其它操作系统的便携式电子设备。上述便携式电子设备也可以是其它便携式电子设备，例如数码相机。还应当理解的是，在本申请其他一些实施例中，上述电子设备100也可以不是便携式电子设备，而是台式计算机等。
通常情况下，电子设备100可以支持多种应用。比如以下应用中的一个或多个：相机应用、即时消息收发应用、照片管理应用等。其中，即时消息收发应用可以有多种。比如微信、腾讯聊天软件(QQ)、WhatsApp Messenger、连我(Line)、照片分享(instagram)、Kakao Talk、钉钉等。用户通过即时消息收发应用，可以将文字、语音、图片、视频文件 以及其他各种文件等信息发送给其他联系人；或者，用户可以通过即时消息收发应用实现与其他联系人的视频或音频通话。
下文以电子设备100是手机100为例，且以手机具有内置电池为例进行说明，图2示出了手机100的结构示意图。
手机100可以包括处理器110，外部存储器接口120，内部存储器121，通用串行总线(universal serial bus，USB)接口130，充电管理模块140，电源管理模块141，电池142，天线1，天线2，移动通信模块150，无线通信模块160，音频模块170，扬声器170A，受话器170B，麦克风170C，耳机接口170D，传感器模块180，按键190，马达191，指示器192，摄像头193，显示屏194，以及用户标识模块(subscriber identification module，SIM)卡接口195等。其中传感器模块180可以包括指纹传感器180H、触摸传感器180K。
处理器110可以包括一个或多个处理单元，例如：处理器110可以包括应用处理器(application processor，AP)，调制解调处理器，图形处理器(graphics processing unit，GPU)，图像信号处理器(image signal processor，ISP)，控制器，存储器，视频编解码器，数字信号处理器(digital signal processor，DSP)，基带处理器，和/或神经网络处理器(neural-network processing unit，NPU)等。其中，不同的处理单元可以是独立的器件，也可以集成在一个或多个处理器中。
其中，控制器可以是手机100的神经中枢和指挥中心。控制器可以根据指令操作码和时序信号，产生操作控制信号，完成取指令和执行指令的控制。处理器110中还可以设置存储器，用于存储指令和数据。在一些实施例中，处理器110中的存储器为高速缓冲存储器。该存储器可以保存处理器110刚用过或循环使用的指令或数据。如果处理器110需要再次使用该指令或数据，可从所述存储器中直接调用。避免了重复存取，减少了处理器110的等待时间，因而提高了系统的效率。
USB接口130是符合USB标准规范的接口，具体可以是迷你(mini)USB接口，微型(micro)USB接口，USB类型C(USB Type C)接口等。USB接口130可以用于连接电源适配器为手机100充电，也可以用于手机100与外围设备之间传输数据。当手机100通过USB接口130与充电设备(比如电源适配器)连接时，手机100可以通过USB接口130与电源适配器传输电能。具体而言，手机100的USB接口130(比如USB type-c接口)中的配置信号线(configuration channel，cc)会检测电源适配器发送的电流，实现手机100和电源适配器之间的电流传输。
需要说明的是，图1中以手机100通过USB接口130与电源适配器连接为例，在实际应用中，手机100还可以通过其它方式与电源适配器连接，比如，在无线充电场景下，手机100通过发射端线圈与电源适配器中的接收端线圈之间的磁场耦合作用传输电能，或者有线充电场景下，通过其它类型充电接口与电源适配器连接传输电能。因此，本申请实施例不限定手机100与电源适配器之间的连接方式。
应理解，当手机100通过USB接口130与电源适配器连接时，手机100与电源适配器之间的电能传输可以通过USB接口130实现；当手机100使用无线充电的方式进行充电，比如手机100通过蓝牙连接的方式与电源适配器无线连接，这样的话，手机100与电源适配器之间的电能传输可以通过蓝牙传输。手机100与电源适配器之间的电能传输过程包括手机100识别电源适配器的供电能力等过程，具体内容在后文介绍。其中，电源适配器和 手机100可以支持相同的协议，比如充电协议(power delivery protocol，PDP)、超级快充协议(super charging protocol，SCP)、快速充电协议(fast charging protocol，FCP)等。电协议还可以分为私有充电协议和公有充电协议。私有充电协议如SCP，公有充电协议如(universal fast charging specification,UFCS)融合快速充电技术规范和电池充电规范1.2版本(battery charging specification revision 1.2，BC1.2)。
下面以图1的(a)所示的应用场景为例，介绍手机100的充电过程。
电源适配器与外部的电源(比如家用电等)连接，从外部的电源(比如家用电等)处获取电能，然后将获取的电能通过USB接口130输入到手机100(比如输入到手机100中的充电管理模块140)。充电管理模块140用于管理充电过程。比如，充电管理模块140用于决定将从USB接口130接收的电能提供给电源管理模块141还是提供给电池142。电源管理模块141接收电池142和/或充电管理模块140输入的电能，为处理器110，内部存储器121，通过外部存储器接口120为外部存储器，显示屏194，摄像头193，和无线通信模块160等外围部件供电。比如，当手机100未与电源适配器连接时，电源管理模块141接收电池142输入的电能，为各个部件供电。当手机100与电源适配器连接并进行充电时，电源管理模块141接收充电管理模块140输入的电能，为各个部件供电，当然，当手机100与电源适配器连接并进行充电时，电源管理模块141也可以接收电池142输入的电能，为各个部件供电。需要说明的是，电源管理模块141为各个部件供电可以有先后顺序，比如先为处理器110供电，然后为其它部件供电，当电源管理模块141为处理器110供电，处理器110启动之后，可以通知电源管理模块141为其它部件中的哪些部分供电，或者不为哪些部件供电等。
因此，手机100通过电源适配器与外部的电源(比如家用电)连接后，充电的过程可以如下：
电源适配器接收外部的电源的电能后，通过USB接口130将电能输入给充电管理模块140。充电管理模块140一方面为电池142蓄电，另一方面为电源管理模块141提供输入电能；或者，充电管理模块140仅为电池142蓄电，电源管理模块141再从电池142获取电能为各个部件(比如处理器110，内部存储器121，显示屏194，摄像头193，和无线通信模块160等)供电。
需要说明的是，电源管理模块141可以和处理器110连接，处理器110可以通过电源管理模块141决定为哪些部件供电，比如，手机100以较低功耗的工作模式开机时，处理器110确定显示屏194需要供电，无线通信模块160不需要供电，则电源管理模块141为显示屏194供电，不为无线通信模块160供电，具体内容将在后文介绍。
电源管理模块141可以提供json配置接口，json配置接口可配置不同产品的策略开关，举例来说，策略开关可以为历史数据清空开关，这是避免出现某版本软件错误导致充电协议无法识别的情况。
应理解，当手机100未连接电源适配器时，手机100可以通过电池142中储存的电能来为各个器件供电。
手机100的无线通信功能可以通过天线1，天线2，移动通信模块150，无线通信模块160等实现。天线1和天线2用于发射和接收电磁波信号。手机100中的每个天线可用于覆盖单个或多个通信频带。不同的天线还可以复用，以提高天线的利用率。例如：可以将天线1复用为无线局域网的分集天线。在另外一些实施例中，天线可以和调谐开关结合使 用。
移动通信模块150可以提供应用在手机100上的包括2G/3G/4G/5G等无线通信的解决方案。移动通信模块150可以包括至少一个滤波器，开关，功率放大器，低噪声放大器(low noise amplifier，LNA)等。移动通信模块150可以由天线1接收电磁波，并对接收的电磁波进行滤波，放大等处理，传送至调制解调处理器进行解调。移动通信模块150还可以对经调制解调处理器调制后的信号放大，经天线1转为电磁波辐射出去。在一些实施例中，移动通信模块150的至少部分功能模块可以被设置于处理器110中。在一些实施例中，移动通信模块150的至少部分功能模块可以与处理器110的至少部分模块被设置在同一个器件中。
无线通信模块160可以提供应用在手机100上的包括无线局域网(wireless local area networks，WLAN)(如无线保真(wireless fidelity，Wi-Fi)网络)，蓝牙(bluetooth，BT)，全球导航卫星系统(global navigation satellite system，GNSS)，调频(frequency modulation，FM)，近距离无线通信技术(near field communication，NFC)，红外技术(infrared，IR)等无线通信的解决方案。无线通信模块160可以是集成至少一个通信处理模块的一个或多个器件。无线通信模块160经由天线2接收电磁波，将电磁波信号调频以及滤波处理，将处理后的信号发送到处理器110。无线通信模块160还可以从处理器110接收待发送的信号，对其进行调频，放大，经天线2转为电磁波辐射出去。
在一些实施例中，手机100的天线1和移动通信模块150耦合，天线2和无线通信模块160耦合，使得手机100可以通过无线通信技术与网络以及其他设备通信。所述无线通信技术可以包括全球移动通讯系统(global system for mobile communications，GSM)，通用分组无线服务(general packet radio service，GPRS)，码分多址接入(code division multiple access，CDMA)，宽带码分多址(wideband code division multiple access，WCDMA)，时分码分多址(time-division code division multiple access，TD-SCDMA)，长期演进(long term evolution，LTE)，BT，GNSS，WLAN，NFC，FM，和/或IR技术等。所述GNSS可以包括全球卫星定位系统(global positioning system，GPS)，全球导航卫星系统(global navigation satellite system，GLONASS)，北斗卫星导航系统(beidou navigation satellite system，BDS)，准天顶卫星系统(quasi-zenith satellite system，QZSS)和/或星基增强系统(satellite based augmentation systems，SBAS)。

电子设备的充电方法
下面介绍手机100的充电流程，如图3所示，具体充电流程如下：
步骤301：手机100与电源适配器连接。
步骤302：手机100进行充电协议的充电识别。
充电识别过程(也可以称为协议握手过程)指手机100与电源适配器之间相互确认充电协议的过程，手机100与电源适配器可以共同支持多种充电协议，手机100与电源适配器在其中一种充电协议进行充电识别成功后，才能进入充电状态。充电识别过程具体可以为手机100获取来自电源适配器的充电协议握手包时，确定手机中存储的充电协议中与充电协议握手包匹配的充电协议，手机100根据与充电协议握手包匹配的充电协议，进行应答，手机100向电源适配器发送特定消息或读取电源适配器的标识，若收到电源适配器的回复消息或读取到的电源适配器的标识为符合手机100侧的预期值，则说明充电识别成功，手机100也可以直接选取充电协议向电源适配器发送该充电协议对应的特定消息或读取电源适配器的标识。
待手机100进行充电协议的充电识别成功后，执行步骤303。
步骤303：手机100进入充电状态。
步骤304：手机100充电完成或与电源适配器正常断开。
其中，图3示出的流程对于其他电子设备也同样适用。
对于多种充电协议，手机100通过不断地切换充电协议去进行充电识别，固然可以最终对某个充电协议也充电识别成功。然而，出于电源适配器老旧等原因，可能出现充电协议支持但充电识别不通过的情况。而在充电识别成功之前手机100并不能进入充电状态，在充电识别期间会持续损失功率。因此，如何让电子设备迅速匹配到合适的充电协议，以及如何减少终端设备在充电识别期间的损失功率，是至关重要的。
为了使得电子设备迅速地匹配到合适的充电协议，需要对充电协议做更加合理、精准的选取。参见图4，为本申请实施例提供的电子设备的充电方法的流程示意图。该方法可以应用于上述图1所示的或者与图1功能结构类似的电子设备上，即该方法可由电子设备中的各个硬件部分结合相应的软件程序来执行，可以按照以下步骤执行：
步骤401：获取至少两条第一记录。
步骤402：根据所述至少两条第一记录，从所述P种充电协议中确定Q种充电协议。
步骤403：从所述Q种充电协议中选取充电协议，根据选取到的充电协议对所述电子设备充电识别，直至选取到与所述电子设备充电识别成功的目标充电协议，并根据所述目标充电协议对所述电子设备充电。
所述至少两条第一记录为电子设备与充电设备对P种充电协议已执行充电识别的记录，至少两条第一记录既可以是一个时段内连续记录的所有充电识别的记录，也可以是一个时段内的部分充电识别的记录。
P种充电协议为电子设备与充电设备共同支持的充电协议。电子设备中存储有S个充电协议(即电子设备支持的充电协议)，S大于或等于P，那么P种充电协议可以按照以下方式获得：以手机100与电源适配器为例，电源适配器与手机100连接后，若手机100与电源适配器对S个充电协议中的任一充电协议进行充电识别成功，则记录电源适配器的标识，以及记录该充电识别成功的充电协议，标记该充电识别成功的充电协议为电子设备与 充电设备共同支持的充电协议，S个充电协议中的充电协议都进行上述过程，得到S个充电协议中电子设备与充电设备共同支持的充电协议，便能得到P种充电协议，也可以从中选取部分充电协议作为P种充电协议。
针对任一所述至少两条第一记录中第一记录，该第一记录中可以记录对第一充电协议一次充电识别的成功或失败结果(对第一充电协议充电识别成功的结果可以称为合法记录，对第一充电协议充电识别失败的结果可以称为非法记录)，也可以记录该次充电协议识别的充电识别时长以及充电识别后的平均充电电流，第一充电协议为所述P种充电协议中任一种充电协议。其中，充电识别的成功或失败可以按以下定义：充电识别成功为充电识别过程中收到已连接通知并在预设时长内有持续电流的状态；充电识别过程中出现收到已连接通知但无已断开通知的异常状态，或反复连接后无电流的异常状态，则记录该次充电识别为失败。需要说明的是，上述充电识别成功或失败的定义仅作为示例，在一些实施例中，还可以设置充电识别成功或失败的其他判定方式，举例来说，可以根据充电电流和充电电压进行判定，如对任一充电协议开始充电识别起，若在预设时长后，对该充电协议的充电电流仍小于充电电流阈值，则确定对该充电协议充电识别失败，反之则确定对该充电协议充电识别成功，根据充电电压的判定同理。
第一记录生成方式可以为：在电子设备执行了充电识别后，电子设备的充电驱动软件向充电应用(如native服务)发送通知信息，充电设备根据通知信息生成第一记录。电子设备中可以只有一个充电设备的充电识别的记录，也可以有多个充电设备的充电识别的记录，可以用通过不同的充电设备的标识来区分不同的充电设备的充电识别的记录，充电设备的标识以及充电识别的结果。其中，充电设备的标识可以按照以下方式生成：如通过充电设备的产品序列码(serial number，SN)与供应商身份标识(vendor id，VID)生成哈希值，作为充电设备的标识。
另外，至少两条第一记录的最大数量，或者每种充电协议的第一记录数量可以限定为固定容量，也可以限定最低数量阈值，最多只维持固定容量的第一记录，举例来说，固定容量可以设置为100条，那么充电设备中可以只保存时间顺序上最新的100条第一记录，若又有新生成的第一记录，那么可以将最早的第一记录删除，添加新生成的第一记录，从而使得第一记录维持100条的数量，再如最低数量阈值为10，那么在电子设备中存储的第一记录的数量小于10时，可以不获取，待第一记录的数量大于或等于10时再获取，作为至少两条第一记录。
所述P种充电协议为所述电子设备与所述充电设备共同支持的充电协议。电子设备支持的充电协议和充电设备支持的充电协议有相同的，也可能有不同的，P种充电协议是既被电子设备支持又被充电设备支持的充电协议。
所述Q种充电协议满足预设充电识别条件，P，Q为正整数，且P大于或等于Q，也可以限定P大于Q，那么当在步骤402中应用时，便可以确保从Q种充电协议中筛选掉了充电协议，在步骤403中应用时，可以在更小的充电协议的范围内执行，提升了选取出目标充电协议的效率。
需要说明的是，从Q种充电协议中选取充电协议时，每次只能选取一个充电协议，并根据选取到的这个充电协议对电子设备进行充电识别，当选取到的充电协议对电子设备进行充电识别成功时，说明选取到的充电协议就是目标充电协议，便可以根据目标充电协议对电子设备充电。
本申请实施例提供的电子设备的充电方法中，从所述P种充电协议中确定Q种充电协议的实现方式可以有多种，这些实现方式可以应用于步骤402，具体可以如下：
第一种：
抽样选取至少两条第一记录中第一记录集合，将第一记录集合中充电识别成功的充电协议，作为Q种充电协议。
举例来说，P种充电协议为10种充电协议，至少两条第一记录为500条第一记录，随机选取其中200条第一记录，200条第一记录中包括7种充电识别成功的充电协议，那么Q为7，这7种充电识别成功的充电协议便是Q种充电协议。再如，为了选取第一记录集合更加均匀，还可以按设定步长来选取第一记录，举例来说，可以按照时间由近及远的顺序，选取步长为10，选取第1条、第11条、第21条…第491条第一记录，这49条记录中包括5种充电识别成功的充电协议，那么Q为5，这5种充电识别成功的充电协议便是Q种充电协议。
第二种：
根据所述P种充电协议在所述至少两条第一记录中充电识别的统计分析指标，确定所述Q种充电协议。
至于根据哪些统计分析指标，以及如何确定所述Q种充电协议，可以基于需求灵活设置，具体来说可以如下：
第(1)种方式：
步骤(1-1)：根据所述P种充电协议在所述至少两条第一记录中充电识别的识别成功次数，确定第一协议集合。和\或
步骤(1-2)：根据所述P种充电协议在所述至少两条第一记录中充电识别的识别失败次数，确定第二协议集合。
步骤(1-3)：根据所述第一协议集合和\或所述第二协议集合，确定所述Q种充电协议。
步骤(1-1)以及步骤(1-2)可以通过设置阈值来确定相应协议集合，比如步骤(1-1)中可以将识别成功次数大于成功次数阈值的充电协议作为第一协议集合，或者按识别成功次数从大到小的顺序选前面Q种充电协议作为第一协议集合；相应地，步骤(1-2)中也可以将识别失败次数小于失败次数阈值的充电协议作为第二协议集合，或者按识别失败次数从小到大的顺序选前面Q种充电协议作为第二协议集合，可选的，失败次数阈值为1。
步骤(1-1)和步骤(1-2)可以择一执行，也可以均执行，若步骤(1-1)和步骤(1-2)择一执行，那么便仅根据择一执行得到的协议集合确定所述Q种充电协议，比如只执行步骤(1-1)，那么便根据第一协议集合，确定所述Q种充电协议，可以将第一协议集合作为Q种充电协议；相应地，若步骤(1-1)和步骤(1-2)均执行，可以根据第一协议集合和第二协议集合，确定所述Q种充电协议，如将第一协议集合和第二协议集合的交集，作为所述Q种充电协议。
值得一提的是，步骤(1-1)和步骤(1-2)的实质并不相同，对于识别失败次数少的充电协议，该充电协议的识别成功次数未必就高。举例来说，P种充电协议为充电协议A、充电协议B和充电协议C，至少两条第一记录为500条第一记录，其中，充电协议A的识别成功次数181次，识别失败次数19次，充电协议B的识别成功次数160次，识别失败次数8次，充电协议C的识别成功次数120次，识别失败次数12次。
若按识别成功次数选2个充电协议，则是充电协议A和充电协议B；若按识别失败次数选2个充电协议，则是充电协议B和充电协议C。
第(2)种方式：
根据所述P种充电协议在所述至少两条第一记录中充电识别的识别成功率，确定所述Q种充电协议。
上述步骤可以通过设置阈值来确定Q种充电协议，比如上述步骤中可以将识别成功率大于成功率阈值的充电协议作为Q种充电协议。
需要说明的是，由于充电协议的成功率和失败率之和为1，因此按照识别成功率和识别失败率确定所述Q种充电协议的步骤实质上一致。
第(3)种方式：
统计分析指标可以考虑时段划分，所述至少两条第一记录可以包括在至少两个时段内的第一记录时，可以如以下步骤所述：
步骤(3-1)：将所述P种充电协议中在所述至少两个时段内充电识别的识别成功次数和\或识别成功率不递减的充电协议，作为第三协议集合。和\或
步骤(3-2)：将所述P种充电协议中在所述至少两个时段内充电识别的识别失败次数和\或识别失败率不递增的充电协议，作为第四协议集合。
步骤(3-3)：根据所述第三协议集合和\或所述第四协议集合，确定所述Q种充电协议。
需要说明的是，至少两个时段可以为至少两条第一记录，也可以为至少两条第一记录中选取的两个时段以上的第一记录，至少两个时段可以设置大于时段个数阈值，如考察在3个时段内充电识别的识别成功次数。
步骤(3-1)和步骤(3-2)可以择一执行，也可以均执行，由于步骤(3-1)或步骤(3-2)中也包括多种方案，也可以按步骤(3-1)或步骤(3-2)中的某一种方案执行，若步骤(3-1)和步骤(3-2)择一执行，那么便仅根据择一执行得到的协议集合确定所述Q种充电协议，比如只执行步骤(3-1)中的一种方案，那么将所述P种充电协议中在所述至少两个时段内充电识别的识别成功次数不递减的充电协议，作为Q种充电协议；相应地，若步骤(3-1)和步骤(3-2)均执行，可以根据第三协议集合和第四协议集合，确定所述Q种充电协议，如将第三协议集合和第四协议集合的交集，作为所述Q种充电协议。
由于一次性只能选取一个充电协议进行充电识别，若选取到的充电协议对所述电子设备充电识别成功，那该充电协议便是目标充电协议，否则，按照继续选取下一充电协议进行充电识别，因此选取充电协议的顺序对于能否迅速选取到目标充电协议至关重要。本申请实施例提供的电子设备的充电方法中，如何确定Q种充电协议中充电协议的选取顺序的实现方式有多种，这些实现方式可以应用于步骤403，具体可以如下：
第一种：
获取至少两条第二记录，所述至少两条第二记录为所述电子设备与所述充电设备对所述P种充电协议已执行充电识别的记录，至少两条第二记录可以为至少两条第一记录，根据Q种充电协议对应充电识别成功的第二记录在所述至少两条第二记录的生成顺序，确定从所述Q种充电协议中选取充电协议的选取顺序。
举例来说，Q种充电协议为：充电协议A、充电协议B和充电协议C，至少两条第二记录按照生成顺序(先生成的在前)排列为：B，成功；A，失败；C，成功；A，成功；那么Q种充电协议对应充电识别成功的第二记录在所述至少两条第二记录的生成顺序便是充电协议B、充电协议C、充电协议A。
当上述方式应用于步骤403时，可以将Q种充电协议对应充电识别成功的第二记录在所述至少两条第二记录的生成顺序的逆序，作为从所述Q种充电协议中选取充电协议的选取顺序，那么上述例子中，从所述Q种充电协议中选取充电协议的选取顺序便是充电协议A、充电协议B、充电协议C，即优先选取时间临近且充电识别成功的充电协议。
第二种：
获取至少两条第二记录，所述至少两条第二记录为所述电子设备与所述充电设备对所述P种充电协议已执行充电识别的记录；根据所述Q种充电协议在所述至少两条第二记录中充电识别的统计分析指标和\或所述Q种充电协议的充电效率指标，确定从所述Q种充电协议中选取充电协议的选取顺序。
第二记录与第一记录的实质相同，第二记录的生成方式等可以参照第一记录。至少两条第二记录可以是至少两条第一记录，也可以不是至少两条第一记录，如与至少两条第一记录的不同生成时间或不同充电协议的记录。
需要说明的是，任一充电协议的充电效率指标为该充电协议的额定充电功率，或者是根据该充电协议的额定充电功率与该充电协议的硬件效率确定的，或者是根据该充电协议在所述至少两条第二记录中记录的平均充电电流确定的。
其中，由于不同充电协议使用的硬件充电通道不一定相同，在充电设备对电子设备充电后，实际充电功率可能并不是额定充电功率，而实际充电功率与额定充电功率的比值便是硬件效率。
具体来说，确定选取顺序的实现方式可以如下：
第(1)种方式：
针对所述Q种充电协议中任一种充电协议，根据该充电协议的统计分析指标对应的第一评分值和第一权重值，以及该充电协议的充电效率指标对应的第二评分值和第二权重值，确定该充电协议的综合评分值；根据所述Q种充电协议的综合评分值，确定所述选取顺序。
第(1)种方式可以应用于步骤403，举例来说，统计分析指标为充电协议在至少两条第二记录中的识别成功率，充电效率指标为额定充电功率，第一权重值为0.6，第二权重值为0.4；第一评分值为充电协议在至少两条第二记录中的识别成功率乘100，如第二充电协议为Q种充电协议中任一种充电协议，第二充电协议在至少两条第二记录中的识别成功率为0.90，那么第一评分值便是90，第二评分值是第二充电协议的额定充电功率与Q种充电协议中最高额度充电功率的比值乘100，如Q种充电协议的额度充电功率包括25W、20W、15W，第二充电协议的额定充电功率为15W，那么第二评分值便是60，所以第二充电协议的综合评分值为78。在计算出Q种充电协议的综合评分值后，可以按照综合评分值从大到小的选取顺序选取Q种充电协议。
上述例子仅作为示例描述第(1)种方式，在选取不同的统计分析指标、充电效率指标以及评分机制后，均可以按照相应方式计算综合评分值，并确定选取顺序。
第(2)种方式：
将所述Q种充电协议在所述至少两条第二记录中充电识别的识别成功次数或识别成功率从大到小的顺序，或者所述Q种充电协议在所述至少两条第二记录中充电识别的识别失败次数或识别失败率从小到大的顺序，作为所述选取顺序。
值得一提的是，所述Q种充电协议在所述至少两条第二记录中识别成功率从大到小的顺序与相应识别失败率从小到大的顺序实质相同；而所述Q种充电协议在所述至少两条第 二记录中识别成功次数从大到小的顺序与相应识别失败次数从小到大的顺序的实质并不相同。
第(3)种方式：
将所述Q种充电协议的充电效率指标从大到小的顺序，作为所述选取顺序。
举例来说，可以将Q种充电协议的平均充电电流从大到小的顺序，作为所述选取顺序。
本申请实施例中，通过对充电设备的充电识别记录，分析各充电协议的历史充电识别情况，对充电识别异常的充电协议进行排除，减少了一部分无法充电或频繁断充的异常情形。从而在选取充电协议的过程中，实现了充电设备与电子设备之间充电协议的快速选择，可以更迅速地匹配到合适的充电协议，提升了用户体验。
上述从所述P种充电协议中确定Q种充电协议的实现方式，以及确定从Q种充电协议中选取充电协议顺序的实现方式，均可应用于充电设备的充电流程，以手机100以及步骤(1-1)～步骤(1-3)为例，当步骤(1-1)～步骤(1-3)应用于手机100时，以按识别成功次数选取充电协议为例，手机100的充电方法的流程可以如图5所示，具体如下：
步骤501：手机100与电源适配器连接。
步骤502：手机100获取电源适配器的标识。
步骤503：确定手机100中保存的第一充电协议充电识别成功的第一记录个数是否大于成功次数阈值。
第一充电协议为P种充电协议中任一种充电协议，若是，执行步骤504，否则，更新第一充电协议，并重新执行步骤503。
步骤504：手机100进入第一充电协议的充电识别。
步骤505：手机100生成第一充电协议的充电识别的第一记录。
步骤506：确定手机100对第一充电协议的充电识别是否成功，若是，执行步骤507，否则，更新第一充电协议，并返回步骤503。
步骤507：手机100进入充电状态。
步骤508：手机100充电完成或与电源适配器正常断开。
