具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
在本公开实施例使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开实施例。在本公开实施例和所附权利要求书中所使用的单数形式的“一种”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本公开实施例可能采用术语第一、第二、第三等来描述各种信息， 但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本公开实施例范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”
出于简洁和便于理解的目的，本文在表征大小关系时，所使用的术语为“大于”或“小于”、“高于”或“低于”。但对于本领域技术人员来说，可以理解：术语“大于”也涵盖了“大于等于”的含义，“小于”也涵盖了“小于等于”的含义；术语“高于”涵盖了“高于等于”的含义，“低于”也涵盖了“低于等于”的含义。
下面结合参考附图描述本公开的快充检测方法、装置、电子设备及存储介质。需要说明的是，下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。
为了便于理解，首先介绍本申请涉及的原理。
电力输送(power delivery，PD)和快速充电(Quick Charge，QC)是当前主流的快速充电协议，随着技术的发展，快充技术为用户提供了便利，但也有越来越多的用户来到售后网点，报修声称充电慢的故障。
在生产制造工厂，可以采用恒定电源、假电池(Dummy battery)等可以提供恒定电压和/或恒定电流的供电设备进行充电检测，或者，根据相应协议进行充电检测。但是，上述供电设备的设备费用较高，不便于在售后网点适用，且充电检测涉及到手机端的权限，只能在工厂包版本下进行检测，用户版本则没有检测权限。
因此，售后网点通常使用电量计检测充电电流和/或充电功率的大小是否达到了参数规格，然而，充电的基本原理是：首先0.1CC进行充电激活、然后恒流充电、再恒压充电、最后涓电流充电直到充满。这就意味着，标称的充电功率，比如号称120W快充的产品，其实只有在电池电量较低的时候，才能达到该功率，充电过程中并不是始终使用该120W进行充电。举例说明，某款手机从零电量充电到达满电量的充电曲线如图1所示。因此，当前售后网点在充电检测时需要先将电子设备的电量降低到一定范围。
同时，电子设备的种类、所处环境的温度、湿度不同，也会导致充电曲线不同，生产制造工厂实验得出的充电曲线不具有普适性。因此，本公开提出一种快充检测方法，本方法的使用成本较低，且具有普适性。
图2是根据本公开一个实施例的快充检测方法的流程图，如图2所示，该方法包括以下步骤：
S201，获取第一终端设备的第一充电信息。
本公开实施例中，第一终端设备为需要进行快充检测的电子设备，第一充电信息中可以包括第一终端设备的当前电量、充电电流、充电电压和充电功率等信息。
作为一种可能的实施方式，第一终端设备在测试期间通过电量计连接电源适配器，通过这种方式，电量计可以在充电过程中读取第一终端设备的当前电量、充电电流、充电电压和充电功率，作为第一充电信息。可选地，还可以从第一终端设备的显示屏幕上直接读取第一终端设备的当前电量，或者，通过万用表等其它测量设备获取第一终端设备的充电电流、充电电压和充电功率等信息。
S202，获取用于对第一终端设备进行快充检测的目标充电图谱。
作为一种可能的实施方式，云服务器中存储有充电图谱集，充电图谱集中包括多个候选充电图谱，一个候选充电图谱中包括一种电子设备的充电信息。可选地，为了考虑环境温度和湿度对充电性能的影响，还可以对候选充电图谱在区域和季节方面进行细分，例如，候选充电图谱1中可以包括电子设备甲在A区域的冬天的充电信息。
可选地，候选充电图谱按照电子设备的种类、所在区域、所处季节等多个分类标准分类存储，根据第一终端设备的种类、所在区域和所处季节等信息，从云服务器中获取对应的目标充电图谱。
需要说明的是，在对第一终端设备进行快充检测之前，需要搜集多个不存在快充故障的电子设备的充电信息，对充电信息进行学习，生成候选充电图谱。
S203，根据第一充电信息和目标充电图谱，对第一终端设备的快充异常进行检测。
目标充电图谱中包括第一终端设备在任一电量下对应的标准充电电流、标准充电电压和标准充电功率等信息，基于第一终端设备的当前电量，将第一终端设备的第一充电信息与目标充电图谱中的标准信息做对比，对第一终端设备的快充异常进行检测，可以降低充电检测的使用成本，并且具有普适性。
可选地，获取第一充电信息与目标充电图谱中标准信息的差异值，当差异值小于设定区间时，判断第一终端设备不存在快充异常，当差异值大于设定区间时，判断第一终端设备存在快充异常。
可选地，终端设备可以为手机、便携式电脑、pad、可穿戴设备等。
本公开实施例中，获取第一终端设备的第一充电信息，获取用于对第一终端设备进行快充检测的目标充电图谱，根据第一充电信息和目标充电图谱，对第一终端设备的快充异常进行检测。本公开实施例中通过获取目标充电图谱，可以得到第一终端设备在任一电量 下对应的标准充电电流和标准充电功率，第一充电信息中包括第一终端设备的当前电量、充电电流和充电功率，与目标充电图谱中的数据进行对比，即可判断电子设备是否存在充电慢的故障，通过这种方式，无需预先对电子设备进行放电，节约了充电检测时间。同时，可以针对不同区域构建多个目标充电图谱，避免环境温度和湿度的影响。
图3是根据本公开一个实施例的快充检测方法的流程图，如图3所示，该方法可以包括以下步骤：
S301，接收第一终端设备上报的故障代码，并识别故障代码为快充故障代码。
图4为本公开实施例的一种应用场景，在图4所示的场景中，第一终端设备为手机终端，第一终端设备与上位机相连。在检测过程中，上位机可以获取并识别第一终端设备上报的故障代码，响应于故障代码为快充故障代码，启动快充检测流程。
可选地，第一终端设备与上位机之间采用无线安卓调试桥(Wireless Fidelity android debug bridge，WIFI ADB)的方式连接。WIFI ADB是ADB连接的一种，两个连接设备接入同一个WIFI网络的情况下，可以进行连接。相比于普通有线ADB，WIFI ADB可以解放USB物理端口，实现一边ADB通讯一边充电。
S302，获取第一终端设备的第一标识信息，根据第一标识信息，获取第一终端设备的保险期限。
上位机还可以读取第一终端设备的第一标识信息，根据第一标识信息，可以从服务器中获取第一终端设备的保险期限。可选地，服务器可以为终端设备所注册的工单服务器。例如，上位机可以读取第一终端设备的国际移动设备识别码(International Mobile Equipment Identity，IMEI)等基本信息。IMEI用于在移动电话网络中识别每一部独立的手机等移动通信设备，根据IMEI可以从服务器中获取第一终端设备的激活时间，进而根据第一终端设备的保修时长计算出第一终端设备的保险期限。
需要说明的是，激活时间在服务器中是公开信息，因为这涉及到手机是否予以保修，故该信息不涉密且可以正常读取。
S303，响应于第一终端设备处于保险期限内，获取第一充电信息。
关于获取第一充电信息的介绍可参见上述实施例中相关内容的记载，此处不再赘述。响应于第一终端设备处于保险期限内，可以从电量计中读取第一充电信息。
S304，获取用于对第一终端设备进行快充检测的目标充电图谱。
电子设备的充电性能会受到环境温度和湿度的影响，因此需要从充电图谱集中选取符合第一终端设备所处环境的目标充电图谱。
在一些实施方式中，考虑到不同区域的环境条件不同，根据第一终端设备所在区域的区域标识，从充电图谱集中获取区域对应的充电图谱，作为目标充电图谱。
在另一些实施方式中，考虑到不同区域及不同季节的环境条件不同，根据第一终端设备所在区域的区域标识，从充电图谱集中获取区域对应的候选充电图谱。获取当前所处季节，并获取与当前所处季节匹配的候选充电图谱，作为目标充电图谱。
S305，根据第一充电信息和目标充电图谱，对第一终端设备的快充异常进行检测。
可选地，第一充电信息包括第一终端设备的第一电量和第一充电功率和/或第一充电电流，目标充电图谱包括候选电量与候选充电功率和/或候选充电电流之间的对应关系。
将第一充电信息与目标充电图谱进行比对，以获取与第一电量相同的第一候选电量，以及第一候选电量所对应的第一候选充电功率和/或第一候选充电电流。获取第一充电功率与第一候选充电功率之间的功率差异和/或获取第一充电电流与第一候选充电电流之间的电流差异。响应于功率差异和/或电流差异大于各自的第一设定门限值，则识别第一终端设备出现快充异常。响应于功率差异和电流差异均小于或者等于各自的第一设定门限值，则识别第一终端设备未出现快充异常。
其中，第一设定门限值的大小可以预先设定，可选地，多个售后网点可以设置相同的第一设定门限值，可选地，多个售后网点也可以根据所在区域和所处季节对第一设定门限进行调整。
本公开实施例中，接收第一终端设备上报的故障代码，并识别故障代码为快充故障代码，获取第一终端设备的第一标识信息，根据第一标识信息，获取第一终端设备的保险期限，响应于第一终端设备处于保险期限内，获取第一充电信息，获取用于对第一终端设备进行快充检测的目标充电图谱，根据第一充电信息和目标充电图谱，对第一终端设备的快充异常进行检测。本公开实施例中采用上位机获取第一终端设备的故障代码和第一标识信息，在故障代码为快充故障代码且基于第一标识信息确定第一终端设备处于保险期限内时，对第一终端设备进行快充检测，通过本公开实施例的方式，无需预先对电子设备进行放电，节约了充电检测时间。同时，可以针对不同区域构建多个目标充电图谱，避免环境温度和湿度的影响。
图5是根据本公开一个实施例的快充检测方法的流程图，如图5所示，该方法可以包括以下步骤：
S501，获取多个第二终端设备的第二充电信息，并根据第二充电信息，生成充电图谱。
其中充电图谱可以为候选充电图谱，也可以为目标充电图谱，此处不进行限制。
本公开实施例中，第二终端设备为不存在快充故障的电子设备，第二充电信息中可以包括第二终端设备的当前电量、充电电流、充电电压和充电功率等信息。
作为一种可能的实施方式，第二终端设备在检测期间通过电量计连接电源适配器，通过这种方式，电量计可以在充电过程中读取第二终端设备的当前电量、充电电流、充电电压和充电功率，作为第二充电信息。可选地，还可以从第二终端设备的显示屏幕上直接读取第二终端设备的当前电量，或者，通过万用表等其它测量设备获取第二终端设备的充电电流、充电电压和充电功率等信息。
根据第二充电信息，可以绘制出充电图谱，充电图谱中包括任一电量与充电电流、充电电压或充电功率之间的对应关系。需要说明的是，对于某一用户的第二终端设备，在检测的几分钟内，可能只能贡献几个点的图谱信息，例如，某一第二终端设备可以贡献电量从25％～28％的变化时，对应的充电电流、充电电压和充电功率。但是对于多个用户，即可获取完整图谱信息，完成充电图谱的绘制。
可选地，可以根据第二充电信息绘制出充电图谱，并将充电图谱上传至服务器。可选地，也可以直接将第二充电信息上传至服务器，由服务器对第二充电信息进行处理，绘制出充电图谱。在后续检测过程中，可以从服务器中获取绘制完成的充电图谱，并基于充电图谱判断电子设备是否存在快充故障。
在一些实施方式中，各个售后网点的工程师，登录账号都具有城市的基本信息，因此，上传的充电图谱和/或第二充电信息用于更新本区域的充电曲线，通过这种方式，可以解决环境温度湿度变化对于检测结果的准确性问题。
本公开实施例中，获取多个第二终端设备的第二充电信息，并根据第二充电信息，生成充电图谱。本公开实施例中通过多个不存在快充故障的第二终端设备生成充电图谱，将充电图谱中的数据作为标准数据，即可根据充电图谱判断待检测的第一终端设备是否存在快充故障。
图6是根据本公开一个实施例的快充检测方法的流程图，如图6所示，该方法包括以下步骤：
S601，从候选终端设备中选取第二终端设备。
候选终端设备为到售后网点进行功能检测的电子设备，本公开中可以从在售后网点进行功能检测的电子设备中选取第二终端设备，并学习第二充电信息，为快充检测提供标准的对比数据。
本公开实施例需要学习正常充电信息绘制充电图谱，因此，在获取第二充电信息之前， 需要预先对第二终端设备进行筛选。方法1，获取候选终端设备的故障代码，并选取故障代码为非快充故障代码的候选终端设备，作为第二终端设备。方法2，获取候选终端设备的第二标识信息，根据第二标识信息，获取候选终端设备的注册时间，选取注册时间晚于第二设定门限值的候选终端设备，作为第二终端设备。方法3，结合上述两种筛选方法，选取故障代码为非快充故障代码的候选终端设备，作为候选第二终端设备，并选取注册时间晚于第二设定门限值的候选第二终端设备，作为第二终端设备。
本公开实施例中以方法3作为示例，方法1和方法2也可以参照方法3中的实施方式，此处不在赘述。
需要说明的是，图4所示的应用场景也可用于本公开实施例中的方法，在本公开实施例中，候选终端设备为手机设备，候选终端设备与上位机相连。在检测过程中，上位机可以获取并识别候选终端设备上报的故障代码，若故障代码不是快充故障代码，可以选取该候选终端设备作为候选第二终端设备，启动学习流程。
可选地，候选终端设备与上位机之间采用WIFI ADB的方式连接，通过这种方式，可以实现一边ADB通讯一边充电。
上位机还可以读取候选终端设备的第二标识信息，根据第二标识信息，可以从服务器中获取候选第二终端设备的注册时间，例如，上位机可以读取候选终端设备的IMEI等基本信息，根据IMEI从服务器中获取候选终端设备的注册时间。需要说明的是，注册时间在服务器中是公开信息，因为这涉及到手机是否予以保修，故该信息不涉密且可以正常读取。
为了充电曲线不受到旧设备的影响，只采用新设备的充电信息来绘制充电图谱，选取注册时间晚于第二设定门限值的候选终端设备，作为第二终端设备。若候选终端设备的注册时间早于第二设定门限值，则不参与学习，只进行正常的功能检测。
S602，获取多个第二终端设备的第二充电信息，并根据第二充电信息，生成充电图谱。
关于获取第二充电信息的介绍可参见上述实施例中相关内容的记载，此处不再赘述。响应于从候选终端设备中选取出第二终端设备，可以从电量计中读取第二终端设备的第二充电信息。
电子设备的充电性能会受到环境温度和湿度的影响，因此在生成充电图谱时还需要考虑第二终端设备的所处环境。
在一些实施方式中，获取属于同一区域的第二终端设备，根据属于同一区域的第二终端设备的第二充电信息，生成同一区域对应的充电图谱。
在另一些实施方式中，获取属于同一区域且同一季节的第二终端设备，根据属于同一区域且同一季节的第二终端设备的第二充电信息，生成同一区域下不同季节的充电图谱。
可选地，可以根据售后网点工程师账号的位置信息或售后网点的定位信息判断第二终端设备的所处区域，并且在不同季节对充电图谱进行更新，使充电图谱更为准确。响应于任一区域的充电图谱绘制完成，停止更新充电图谱，充电图谱学习流程结束。
本公开实施例中，从候选终端设备中选取第二终端设备，获取多个第二终端设备的第二充电信息，并根据第二充电信息，生成充电图谱。本公开实施例中采用上位机获取候选终端设备的设备信息，从中选取不存在快充故障的新设备作为第二终端设备，通过本公开的方式，可以在对电子设备进行功能检测的同时获取第二充电信息，为快充检测提供标准的对比数据。
图7是根据本公开一个实施例的快充检测方法的流程图，如图7所示，在一些实施方式中，快充检测方法包括以下步骤：
学习过程：当确定终端设备为非充电故障保修，启动学习流程。待上位机连接后，读取终端设备的IMEI等信息，并根据IMEI等信息从终端设备所关联的工单服务器获取该终端设备的激活时间。当激活时间小于预设门限时，在检测期间记录终端设备的充电信息，并通过上位机对终端设备进行其他功能检测。当激活时间大于预设门限时，只需要通过上位机对终端设备进行其他功能检测。根据记录的充电信息，可以丰富充电图谱中的充电曲线。响应于任一区域的充电图谱绘制完成，停止更新图谱，充电图谱学习流程结束。
检测过程：当确定终端设备为充电故障报修，启动检测流程。待上位机连接后，读取终端设备的IMEI等信息，并根据IMEI等信息从工单服务器端获取该用户的终端设备的激活时间，判断该终端设备是否保修。记录电量计读取的充电信息，将充电信息与充电图谱进行比对判断。当差异值大于设定值时，判断快充功能异常。当差异值小于设定值时，判断快充功能正常。
例如，用户可以携带终端设备前往售后点进行快充检测，终端设备可以与快充检测设备连接，通过该快充检测设备对终端设备进行快充检测流程。可选地，快充检测设备可以为具有快充检测功能的上位机，可以按照图4所示，终端设备与上位机相连。在检测过程中，上位机可以获取并识别终端设备上报的故障代码，响应于故障代码为快充故障代码，启动快充检测流程。
