在充电过程中，一般将电源提供装置(如电源适配器、移动电源(Power Bank)等设备)通过线缆与待充电设备相连，通过电缆将电源提供装置提供的电能传输至待充电设备，以为待充电设备充电。
在介绍本公开实施方式之前，先对QC快速充电协议的原理做简要说明。支持QC快速充电协议的电源提供装置(如QC适配器、QC移动电源)与待充电设备连接后，与待充电设备中的应用处理器(Application Processor，AP)利用USB缆线中的数据线D+/D-进行通信，协商当前适合的电压电流对，以QC2.0协议为例，其支持的电压电流对如表1所示：
表1
Figure PCTCN2020120933-appb-000001
以支持9V/2A的QC协议的待充电设备与QC适配器连接为例，首先当待充电设备的充电接口中插入QC适配器，待充电设备中的AP利用BC1.2协议识别QC适配器提供的连接端口是否为专用充电端口(Dedicated Charging Port，DCP)。如果识别出是DCP，此时数据线D+/D-短接，QC适配器输出5V/2A的电压电流对，可以为待充电设备提供普通充电机制(相较于快速充电模式而言，适配器在普通充电模式下的充电速度比较慢，完全 充满相同容量电池所需要的充电时间更长)。
因为待充电设备AP支持QC快速充电协议，其会启动一个名为HVDCP的服务进程，用于进一步与QC适配器协商是否适用于快速充电的电压和电流。HVDCP进程使数据线D+上加载0.325V的电压并保持1.25秒；当QC适配器在数据线D+上检测到超过1.25秒的0.325V电压时，会断开数据线D+/D-的短接，此时数据线D-上的电压不会随着数据线D+上的电压变化而变化，而是直接下降；待充电设备的AP检测到数据线D-上的电压从0.325V开始下降时，表示AP识别到电源提供装置的类型为QC适配器，并可以开始与QC适配器请求所需要的电压，比如请求9V的电压。此时，AP通过将数据线D+和D-分别设置为3.3V和0.6V来请求9V的电压。而如果需要降低当前的电压到5V，则AP可以将数据线D+和D-分别设置为0.6V和0V。QC适配器检测到数据线D+和D-上相应的电压后，则会输出对应的电压。
需要说明的是，由于不同型号的待充电设备的硬件不同，并不能完全支持表1中的所有电压电流对。例如，某些待充电设备即使识别到QC适配器，但也仅能通过5V/2A电压电流对在普通充电模式下进行充电；而某些待充电设备仅能支持5V/2A和9V/2A两种电流对等。待充电设备具体可以支持的QC协议的充电参数可以在预设的文件中读取。
在相关技术中，除了上述的QC快速充电方案外，还存在着大电流充电技术方案。在大电流快速充电方案中，电源提供装置能够输出相对较大的电流(通常大于2.5A，比如4.5A，5A甚至更高)。电源提供装置例如可以为第一类型快速充电适配器，如最大输出功率为50W(10V/5A)，采用快速充电模式为待充电设备进行充电；或者，电源提供装置还可以为第二类型快速充电适配器，如最大输出功率为20W(5V/4A)，采用快速充电模式为待充电设备进行充电。
如上述，为了在待充电设备中兼容不同的快速充电方案，需要设计一套充电控制方法，来避免不同快速充电方案之间的冲突。
下面具体说明本公开实施方式提供的充电控制方法。
图1是根据一示例性实施方式示出的一种充电控制方法的流程图。该充电控制方法可以应用于待充电设备中。
待充电设备例如可以是终端或通信终端，该终端或通信终端包括但不限于被设置成经由有线线路连接，如经由公共交换电话网络(public switched telephone network，PSTN)、数字用户线路(digital subscriber line，DSL)、数字电缆、直接电缆连接，以及/或另一数据连接/网络和/或经由例如，针对蜂窝网络、无线局域网(wireless local area network，WLAN)、诸如手持数字视频广播(digital video broadcasting handheld，DVB-H)网络的数字电视网络、卫星网络、调幅-调频(amplitude modulation-frequency modulation，AM-FM)广播发送器，以及/或另一通信终端的无线接口接收/发送通信信号的装置。被设置成通过无线接口通信的通信终端可以被称为“无线通信终端”、“无线终端”以及/或“移动终端”。移动终端的示例包括，但不限于卫星或蜂窝电话；可以组合蜂窝无线电电话与数据 处理、传真以及数据通信能力的个人通信系统(personal communication system，PCS)终端；可以包括无线电电话、寻呼机、因特网/内联网接入、Web浏览器、记事簿、日历以及/或全球定位系统(global positioning system，GPS)接收器的个人数字助理(Personal Digital Assistant，PDA)；以及常规膝上型和/或掌上型接收器或包括无线电电话收发器的其它电子装置。此外，该终端还可以包括但不限于诸如电子书阅读器、智能穿戴设备、移动电源(如充电宝、旅充)、电子烟、无线鼠标、无线键盘、无线耳机、蓝牙音箱等具有充电功能的可充电电子设备。
参考图1，充电控制方法10包括：
在步骤S102中，当识别到与待充电设备连接的电源提供装置提供的连接端口为DCP时，确定电源提供装置的类型是否为预设类型或QC类型。
如上述，例如由待充电设备的AP通过BC1.2协议来识别电源提供装置提供的连接端口是否为DCP。
在一些实施例中，AP可以当当识别到与待充电设备连接的电源提供装置提供的连接端口为DCP时，通知待充电设备的控制模块识别电源提供装置的类型是否为预设类型。
在AP识别到DCP后，通过与待充电设备的控制模块进行通信，通知其进一步识别电源提供装置的类型是否为预设类型。
该控制模块例如可以通过独立的微控制单元(Micro Control Unit，MCU)实现，用于控制如上述的大电流快速充电过程。该预设类型例如可以为上述大电流充电方案中的第一类型快速充电适配器或第二类型快速充电适配器。
也即，在识别到DCP之后，AP延迟启动HVDCP服务进程，先通过与控制模块通信，指示控制模块先识别电源提供装置是否为预设类型的电源提供装置。
由于控制模块在识别预设类型的电源提供装置时通常也需要使用USB缆线中的数据线D+/D-来进行识别，因此延迟启动HVDCP服务器进程可以避免两种快速充电方案同时利用D+/D-进行识别而导致的类型识别错误的问题。如果发生类型识别错误，不仅无法进行快速充电，还有可能发生因不合适的充电电压/充电电流而导致的危险。进一步地，AP确定控制模块识别到电源提供装置的类型是否为预设类型。
控制模块在识别到第一类型快速充电适配器或第二类型快速充电适配器后，会通过与AP的通信告知电源提供装置的类型，并且由控制模块来控制该第一类型快速充电适配器或第二类型快速充电适配器为待充电设备充电的过程。而如果控制模块没有识别到第一类型快速充电适配器或第二类型快速充电适配器，也可以通过与AP之间的通信告知AP没有识别到预设类型的电源提供装置。
也即，在一些实施例中，AP可以根据控制模块反馈的类型，确定控制模块识别到电源提供装置的类型是否为预设类型。
而如果控制模块没有识别到第一类型快速充电适配器或第二类型快速充电适配器，不告知AP。或者，由于出现一些错误，导致AP没有收到控制模块的反馈。为了避免AP一 直等待反馈信息，在一些实施例中，AP可以设置一个预设时间，当在预设时间内没有收到控制模块反馈的类型信息时，确定控制模块识别到电源提供装置的类型不为预设类型。通常，控制模块对电源提供装置的类型识别不会超过30秒，因此AP可以将该预设时间设置为30秒，但本公开不以此为限。
当AP确定控制模块识别到电源提供装置的类型不为预设类型时，识别电源提供装置的类型是否为QC类型。
在确定电源提供装置不为预设类型时，AP如可以通过上述的启动HVDCP服务进程来识别电源提供装置的类型是否为QC的类型。具体的识别类型如上述，HVDCP进程使数据线D+上加载0.325V的电压并保持1.25秒；当QC适配器在数据线D+上检测到超过1.25秒的0.325V电压后，会断开数据线D+/D-的短接，此时数据线D-上的电压不会随着数据线D+上的电压变化而变化，而是直接下降；待充电设备的AP检测到数据线D-上的电压从0.325V开始下降时，表示电源提供装置为QC类型的电源提供装置，并且AP可以开始与QC适配器请求所需要的电压，比如请求9V的电压。此时，AP通过将数据线D+和D-分别设置为3.3V和0.6V来请求9V的电压。而如果需要降低当前的电压到5V，则AP可以将数据线D+和D-分别设置为0.6V和0V。QC适配器检测到数据线D+和D-上相应的电压后，则会输出对应的电压。
或者，在一些实施例中，AP也可以在识别到DCP之后，先启动HVDCP服务进程，进行如上述的QC类型识别。
在步骤S104中，当电源提供装置的类型为QC类型时，获取待充电设备中存储的QC协议参数，并根据获取的QC协议参数，控制待充电设备的电池单元进行充电。
如上述，支持QC协议的待充电设备通常会在预设的文档中存储有QC协议的相关参数，例如具体支持的电压电流对参数等。
获取到QC协议参数后，AP可以通过与QC适配器之间的通信，控制QC适配器提供的电压/电流，进而控制对待充电设备的通信。
根据本公开实施方式提供的充电控制方法，针对待充电设备可以同时支持QC快速充电方案和其他快速充电方案的情况，设计了一套充电控制流程，避免了不同种快速充电方案因发生冲突而导致的无法进行快速充电，甚至发生危险的问题。
应清楚地理解，本公开描述了如何形成和使用特定示例，但本公开的原理不限于这些示例的任何细节。相反，基于本公开公开的内容的教导，这些原理能够应用于许多其它实施方式。
图2是根据一示例性实施例示出的另一种充电控制方法的流程图。与图1所示的充电控制方法10不同的是，图2所示的充电控制方法进一步说明了如何根据QC协议，控制待充电设备的电池单元进行充电。也即，图2所示的充电控制方法进一步提供了步骤S104的具体实施例。
参考图2，步骤S104包括：
在步骤S1042中，确定待充电设备中电池单元的电压是否高于预设的电压阈值。
在快速充电过程中，当电池单元快被充满时，通常会出现因电池单元电压虚高而导致电池单元充不满的问题。为了避免该问题，本公开实施例进一步设计了电压回落机制。通过将电池单元当前的电压与预设的电压阈值进行比较，来确定是否需要将当前快速充电使用的高电压(如9V、12V等)调整回低电压(如5V)来继续充电。
在步骤S1044中，当电池单元的电压高于该电压阈值时，请求电源提供装置将输出电压调整为第一电压。
如果电池单元的电压高于该电压阈值，则有可能说明电池单元当前的电压存在虚高的问题。这时可以通过与QC适配器的通信(如上述调整数据线D+和D-上的电压)来请求降低QC适配器调整输出电压的大小，如请求将输出电压调整为第一电压。
第一电压例如为上述的5V电压。
在步骤S1046中，当电池单元的电压低于电压阈值时，请求电源提供装置将输出电压调整为第二电压。
如果电池单元的电压低于电压阈值，则AP可以通过与QC适配器的通信来请求QC适配器将输出电压调整为高于第一电压的第二电压。
其中，第一电压低于所述第二电压，第二电压例如为上述的9V、12V电压等。
如上述，根据本公开实施例提供的充电控制方法，通过设计充电电压回落机制，可以在QC快速充电过程中，避免因电池电压虚高而导致的电池充不满的问题。
需要注意的是，上述附图仅是根据本公开示例性实施方式的方法所包括的处理的示意性说明，而不是限制目的。也即，并非要求或者暗示必须按照该特定顺序来执行这些步骤，或是必须执行全部所示的步骤才能实现期望的结果。附加的或备选的，可以省略某些步骤，将多个步骤合并为一个步骤执行，以及/或者将一个步骤分解为多个步骤执行等。另外，这些处理还可以是在多个模块中同步或异步执行的。
图3是根据一示例性实施例示出的再一种充电控制方法的流程图。与图1所示的充电控制方法10不同的是，图3所示的充电控制方法进一步说明了如何根据QC协议，控制待充电设备的电池单元进行充电。也即，图3所示的充电控制方法进一步提供了步骤S104的另一具体实施例。
参考图3，步骤S104包括：
在步骤S1041中，确定检测到的电源提供装置提供的输出电压是否由第一电压上升至第二电压。
如上述，在AP首先通过BC1.2协议识别到电源提供装置提供的连接端口的类型为DCP时，可以先进入普通充电模式对待充电设备中的电池单元进行充电，同时可以启动相应的线程通过对一些电流参数进行设置来实现充电过程中的自适应操作。所述的自适应操 作例如为根据当前电池的温度进行的自适应操作，也即对应不同的电池温度对应有不同的电流参数值的设置。
AP例如可以通过与待充电设备中用于电压检测的模块的通信来确定输出电压是否发生变化。
在步骤S1043中，当检测到的电源提供装置提供的输出电压由第一电压上升至第二电压时，相应地调整待充电设备中的电流参数的设置。
AP例如可以通过启动一个专用线程来执行该检测操作。为了不影响待充电设备的功耗。该线程例如可以周期地进行，如可以每50毫秒检测一次。
当检测到输出电压的上升后，AP需要对相应地调整上述的电流参数设置，以适应输出电压的变化，如上述由普通充电模式下的5V电压上升为快速充电模式下的9V电压等。
此外，该线程通常仅需在首次检测时运行，一旦进入快速充电模式并达到稳定的电压后，则无需再执行该检测，因此可以暂停该线程的执行，避免对待充电设备功耗的浪费。
充电参数如可以包括下述参数中的至少一种：用于限制电源提供装置的最大输出电流的输入电流参数、用于限制输入到电池单元的最大电流的充电电流参数、用于判断电池单元是否充满的截止电流参数等。
此外，在一些实施例中，步骤S104还可以进一步包括：
在步骤S1045中，确定检测到的电源提供装置提供的输出电压是否由第二电压下降至第一电压。
在输出电压下降时(如上述，为了避免电池电压虚高而设计的输出电压回落机制)，也需要检测输出电压的变化。
例如，AP也可以通过设置专用的线程来执行该检测。为了节省待充电设备的功耗，该线程也可以周期地进行。
在步骤S1047中，当确定检测到的电源提供装置的输出电压由第二电压下降至第一电压时，相应调整待充电设备中的电流参数的设置。
AP在检测到输出电压的下降时，也需要相应地调整电流参数的设置，从而避免出现输出电压改变后自适应参数适用错误的问题。
图4是根据一示例实施方式示出的再一种充电控制方法的流程图。如图4所示的充电控制方法40同样可以应用于待充电设备中。
参考图4，当AP检测到有电源提供装置插入时，通过BC1.2协议进行USB端口识别(步骤S202)。判断识别到的端口是否为DCP(步骤S204)；如果识别到的是DCP，AP可以进入步骤S212，通知控制模块识别电源提供装置的类型是否为预设类型；同时，如果识别到的是DCP，AP还可以进入步骤S206，设置普通充电模式下的输入电流值，该参数用于限制电源提供装置的最大输出电流。进一步设置普通充电模式下的充电电流值，该参数用于限制加载到电池单元的最大充电电流(步骤S208)。输入电流值和充电电流值 共同决定充电过程，加载给电池单元的充电电流的大小不能超过这两个值的最小值。之后，再设置截止电流值(步骤S210)，该电流值用于判断电池单元是否充满。当电池单元的电压高于判断充满的电压阈值同时进入电池单元的电流小于该截止电流值一段预设时间，则判断电池单元充电被充满。
AP在步骤S212中通知控制模块识别预定类型后，确定控制模块识别到的电源提供装置的类型是否为预设类型(步骤S214)；如果是，则启动预设类型快速充电线程，保持与控制模块之间的通信，由控制模块控制电池单元的充电过程(步骤S216)；如果不是，则启动HVDCP服务进程，识别QC类型的适配器，并进入步骤S220，确定电源提供装置的类型是否为QC类型。如果不是QC类型，则返回步骤S206，根据检测到的电池单元的温度自适应的重新设置上述的输入电流值、充电电流值、截止电流值等。而如果是QC类型，则进入步骤S222，启动QC类型适配器的充电过程。之后，确定电池单元的电压是否高于预设的电压阈值(步骤S224)；如果不是，进入步骤S226，请求电源提供装置将输出电压调整为第二电压；并启动一个预设线程来检测由普通模式的输出电压(如5V)升压到第二电压(如9V)的时间点(步骤S228)，在检测到该时间点后返回步骤S206，调整自适应的各电流参数值。如果确定电池单元的电压高于预设的电压阈值，则进入步骤S230，请求电源提供装置将输出电压调整为第一电压。如上述，该操作是为了避免因电池电压虚高而导致电池充不满而设置的输出电压回路机制。同时，AP也可以启动另一个专用线程用于检测输出电压由当前的输出电压(如9V)回落到第一电压(如5V)的时间点(步骤S232)，并在检测到该时间点后返回步骤S206。
需要说明的是，步骤S220仅需要执行一次，也即对是否为QC类型适配器的识别仅需要进行一次。
下述为本公开装置实施例，可以用于执行本公开方法实施例。对于本公开装置实施例中未披露的细节，请参照本公开方法实施例。
图5是根据一示例性实施方式示出的一种待充电设备的框图。
参考图5，待充电设备1包括：充电接口11、电池单元12、第一控制模块13及第二充电模块14。
其中，待充电设备1通过充电接口11与电源提供装置2连接，以为电池单元12充电。
充电接口11例如可以为USB 2.0接口、Micro USB接口或USB TYPE-C接口。在一些实施例中，充电接口11还可以为lightning接口，或者其他任意类型的能够用于充电的并口或串口。
电池单元12可以包括单个包含单电芯或多电芯的锂电池；或者也可以包括两个相互串联的电池单元，每个电池单元为包含单电芯或多电芯的锂电池。
以电池单元包含单电芯为例，对于包含单个电池单元的待充电设备，当使用较大的充电电流为单个电池单元充电时，待充电设备的发热现象会比较严重。为了保证待充电设备 的充电速度，并缓解待充电设备在充电过程中的发热现象，可对电池结构进行改造，使用相互串联的多个电池单元，并对该多个电池单元进行直充，即直接将适配器输出的电压加载到多个电池单元的两端。与单个电池单元方案相比(即认为改进前的单个电池单元的容量与改进后串联多个电池单元的总容量相同)，如果要达到相同的充电速度，多个电池单元所需的充电电流约为单个电池单元所需的充电电流的1/N(N为串联的电池单元的数目)，换句话说，在保证同等充电速度的前提下，多个电池单元串联可以大幅降低充电电流的大小，从而进一步减小待充电设备在充电过程中的发热量。因此，为了提升充电速度并降低待充电设备在充电过程中的发热量，待充电设备可以采用多个串联的电池单元。
第一控制模块13与充电接口11连接，用于当识别到与待充电设备1连接的电源提供装置2提供的连接端口是否为专用充电端口时，通知第二控制模块14识别电源提供装置1的类型是否为预设类型；识别电源提供装置2的类型是否为QC类型；及当识别到电源提供装置2的类型为QC类型时，获取待充电设备1中存储的QC协议参数，并根据QC协议参数，控制待充电设备1的电池单元12进行充电。
在一些实施例中，第一控制模块13用于在控制待充电设备1的电池单元12进行充电时：确定电池单元12的电压是否高于预设的电压阈值；当电池单元12的电压高于电压阈值时，请求电源提供装置2调整输出电压为第一电压；及当电池单元12的电压低于电压阈值时，请求电源提供装置2调整输出电压为第二电压；其中，第一电压低于第二电压。
在一些实施例中，第一控制模块13还用于在控制待充电设备1的电池单元12进行充电时：确定检测到的电源提供装置2提供的输出电压是否由第一电压上升至第二电压；及当确定检测到的电源提供装置2提供的输出电压由第一电压上升至第二电压时，相应调整待充电设备1中的电流参数的设置。
在一些实施例中，第一控制模块13还用于在控制待充电设备1的电池单元12进行充电时：确定检测到的电源提供装置2提供的输出电压是否由第二电压下降至第一电压；及当确定检测到的电源提供装置2提供的输出电压由第二电压下降至第一电压时，相应调整待充电设备1中的电流参数的设置。
在一些实施例中，电流参数包括下述参数中的至少一种：用于限制电源提供装置2的最大输出电流的输入电流参数、用于限制输入到电池单元12的最大电流的充电电流参数、用于判断电池单元12是否被充满的截止电流参数。
在一些实施例中，第一控制模块13用于根据第二控制模块14反馈的类型，确定第二控制模块14识别到电源提供装置2的类型是否为预设类型。
在一些实施例中，第一控制模块13还用于当在预设时间内没有收到第二控制模块14反馈的类型信息时，确定第二控制模块14识别到电源提供装置2的类型不为预设类型。
如上述，第一控制模块13可以为待充电设备1的应用处理器，第二控制模块14为微控制单元(MCU)。
根据本公开实施方式提供的待充电设备，一方面，针对待充电设备可以同时支持QC 快速充电方案和其他快速充电方案的情况，设计了一套充电控制流程，避免了不同种快速充电方案因发生冲突而导致的无法进行快速充电，甚至发生危险的问题；另一方面，通过设计电压回落机制，可以避免在快速充电过程中，因电池单元虚高而导致的电池无法被充满的问题；再一方面，通过对最大输入电流改变时间点的检测，可以及时对自适应操作中的相关参数进行调整，避免在充电过程中使用不合适的参数值。
