请参阅图2，图2为本申请实施例提供的电子设备的结构框图。电子设备可以包括存储和处理电路131，存储和处理电路131可以集成在电路板上。存储和处理电路131可以包括存储单元，例如硬盘驱动存储单元，非易失性存储单元(例如闪存或用于形成固态驱动器的其它电子可编程只读存储单元等)，易失性存储单元(例如静态或动态随机存取存储单元等)等，本申请实施例不作限制。存储和处理电路131中的处理电路可以用于控制电子设备的运转。处理电路可以基于一个或多个微处理单元，微控制器，数字信号处理单元，基带处理单元，功率管理单元，音频编解码器芯片，专用集成电路，显示驱动器集成电路等来实现。

电子设备还包括充电电路133。充电电路133可以为电子设备的电芯14充电。充电电路133可以用于进一步的调节自适配器输入的充电电压和/或充电电流，以满足电池的充电需求。
电子设备配置有充电接口，充电接口123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。该充电接口400通过数据线与适配器连接，适配器从市电获取电能，经过电压变换后，通过数据线传、充电接口400传输至充电电路，因此电能通过充电电路得以充入待充电电芯中。
本公开中的电池14包括外壳以及包裹在外壳内的电芯、电池保护板等组成。电池保护板是对电芯起保护作用的集成电路板。电池保护板上一般具有采样电路以及保护电路。电池14可包括单电芯或多电芯。电池14包括多电芯时，该多个电芯之间可为串联关系。由此，电池14可承受的充电电压为多个电芯可承受的充电电压之和，可提高充电速度，减少充电发热。
例如，以电子设备10为手机为例，当电子设备10的电池14包括单电芯时，内部的单节电芯的电压一般在3.0V～4.35V之间。而当电子设备10的电池14包括两节串联的电芯时，串联的两节电芯的总电压为6.0V-8.7V。由此，相比于单电芯，采用多节电芯串联时，充电电路133的输出电压可以提高。与单节电芯相比，达到同等的充电速度，多节电芯所需的充电电流约为单节电芯所需的充电电流的1/N(N为电子设备10内的相互串联的电芯的数目)。换句话说，在保证同等充电速度(充电电流相同)的前提下，采用多节电芯的方案，可以降低充电电流的大小，从而减少电子设备10在充电过程的发热量。另一方面，与单电芯方案相比，在充电电流保持相同的情况下，采用多电芯串联方案，可提高充电电压，从而提高充电速度。
下面描述一下相关技术中为电子设备10充电的相关适配器。
相关技术中，适配器可以以恒压模式工作，其输出的电压基本维持恒定，比如5V、9V、12V或20V等。输出的电流可以为脉动直流电流(方向不变、幅值大小随时间变化)、交流电流(方向和幅值大小均随时间变化)或恒定直流电流(方向和幅值均不随时间变化)。相关适配器输出的电压并不适合直接加载到电池的两端，而是需要先经过电子设备10内的变换电路进行变换，以得到电子设备10内的电池所预期的充电电压和/或充电电流。
适配器还可以采用电压跟随的方式工作。即适配器和待充电的电子设备10进行双向通信，适配器根据电子设备10反馈所需的充电电压和充电电流，从而调整自身输出的电压和电流，使得输出的电压和电流可以直接加载到电子设备10的电池上，为电池充电，电子设备10无需再次再调整充电电压和充电电流。
变换电路可在不同的充电阶段控制电池的充电电压和/或充电电流。例如，在恒流充电阶段，变换电路可以利用电流反馈环使得进入到电池的电流大小满足电池所预期的第一充电电流的大小。在恒压充电阶段，变换电路可以利用电压反馈环使得加载到电池两端的 电压的大小满足电池所预期的充电电压的大小。在涓流充电阶段，变换电路可以利用电流反馈环使得进入到电池的电流大小满足电池所预期的第二充电电流的大小(第二充电电流小于第一充电电流)。
比如，当相关适配器输出的电压大于电池所预期的充电电压时，变换电路用于对相关适配器输出的电压进行降压变换处理，以使经降压转换后得到的充电电压的大小满足电池所预期的充电电压的大小。
对电子设备10的电池的充电模式大致有“普通充电模式”、“快速充电模式”。普通充电模式是指适配器输出相对较小的电流值(通常小于2.5A)或者以相对较小的功率(通常小于15W)来对待充电设备中的电池进行充电。在普通充电模式下想要完全充满一较大容量电池(如3000毫安时容量的电池)，通常需要花费数个小时的时间。快速充电模式则是指适配器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)或者以相对较大的功率(通常大于等于15W)来对待充电设备中的电池进行充电。相较于普通充电模式而言，适配器在快速充电模式下的充电速度更快，完全充满相同容量电池所需要的充电时间能够明显缩短。
下面描述一下根据PD充电协议对电子设备10充电的PD充电方案。
USB-Power Delivery(USBPD)是目前主流的快充协议之一。是由USB-IF组织制定的一种快速充电规范。USBPD透过USB电缆和连接器增加电力输送，扩展USB应用中的电缆总线供电能力。该规范可实现更高的电压和电流，输送的功率最高可达100瓦，并可以自由的改变电力的输送方向。
请参阅图2，USBPD的通信是将协议层的消息调制成24MHZ的FSK信号并耦合到VBUS上或者从VBUS上获得FSK信号来实现手机和适配器通信的过程。
如图2所示，在USB PD通信中，是将24MHz的FSK通过cAC-Coupling耦合电容耦合到VBUS上的直流电平上的，而为了使24MHz的FSK不对Power Supply或者USBHost的VBUS直流电压产生影响，在回路中同时添加了zIsolation电感组成的低通滤波器过滤掉FSK信号。
支持PD充电协议的PD适配器的充电接口一般包括电压引脚VBUS、接地引脚GND、数据引脚USB_D+(D+)及USB_D-(D-)、第一引脚CC1及第二引脚CC2。当某电子设备10支持PD适配器的充电时，其USB PD协议接口芯片会通过
以电子设备10上的Type-C接口为例说明，Type-C接口的两面各具有12个针脚。其中，TX1+、TX1-，RX1+、RX1-，TX2+、TX2-，RX2+、RX2-为四对差分信号针脚，GND为接地针脚，D+、D-为用于兼容USB2.0的USB差分信号针脚，VBUS为电源针脚，CC1、CC2为用于探测正反插、区分主从、配置VBUS电压等的针脚，SBU1、SBU2为总线针脚。
由于Type-C接口具有四个电源针脚和四个接地针脚，因此，Type-C接口理论上能够支持100W的电源输出，这也是Type-C接口能够实现USB-PD快速充电的原因。在此基础上，USB-PD快速充电是指通过VBUS直流电平上耦合FSK信号来请求适配器调整输出电压和电流的过程，具体包括如下步骤：
步骤1：电子设备10识别插入的适配器是否为支持快速充电的PD适配器，如是，则进行切换，即将Type-C的差分信号针脚改为用于传输DP信号(包括PD命令和数据等)，将TypeC的SBU1、SUB2总线针脚改为用于传输AUX辅助信号。
步骤2：启动USB-PD设备策略管理器，策略管理器监控VBUS的直流电平上耦合的FSK(Frequency-shift keying)信号，并从中解码得到能力资源(Capabilities Source)消息，再根据USB-PD规范解析该消息得出PD适配器支持的所有电压和电流对列表；
步骤3：电子设备10根据用户的配置从Capabilities Source消息中选择一个电压和电流对，并将电压和电流对加载至充电请求(Request)消息的载荷(payload)部分，然后，策略 管理器将FSK信号耦合到VBUS直流电平上。
步骤4：适配器解码FSK信号并发出接收(Accept)消息给电子设备10，同时调整适配器的输出电压和电流。
步骤5：电子设备10接收到Accept消息后，调整充电IC的充电电压和电流。
本公开实施例通过在适用于各种电子设备硬件环境的主充电线程内设置可供调用的PD充电控制脚本的接口，因而可以预先根据电子设备自身硬件环境的特异性来具体设置特定的PD充电控制脚本，以供主充电线程的调用。因此在检测到PD适配器为供电设备时，通过调用PD充电控制脚本，均能够通过调用PD充电控制脚本，以使电子设备能够基于PD充电协议被快速充电。本公开通过将适用于各种电子设备硬件环境的充电步骤与具有特异性的PD充电步骤分离开来，使得无论电子设备是否支持PD充电或所支持PD充电参数是否相同，均能够利用本公开充电控制方法进行充电。因此本方法均基本上可以应用于各种硬件环境的电子设备内，因而具有较好的通用性。
请参阅图3，图3示出了本公开的充电控制方法的流程图。具体的，充电控制方法首先进入主充电线程，主充电线程对具有不同硬件环境的电子设备10均适用，充电控制方法具体包括：
步骤S20，获取适配器的端口类型。
在一实施例中，当电子设备10的充电接口与适配器连接时，电子设备10内的充电控制模块会根据BC1.2充电协议对端口类型进行检测。适配器的端口类型包括SDP(Standard Downstream Port，标准下行端口)、CDP(Charging Downstream Port，充电下行端口)以及DCP(Dedicated Charging Port，专用充电端口)。
步骤S21，根据适配器的端口类型设置电子设备10内充电电路的电路参数，以充电电路的电路参数为电子设备10充电。
在一实施例中，根据所检测到的端口类型不同，如果充电控制模块检测到适配器为SDP类型，则从适配器获取第一充电电流对电子装置进行充电，如果充电控制模块检测到适配器为CDP类型，则从适配器获取第二充电电流对电子装置进行充电。在此以适配器类型为DCP为例说明，当检测到电子设备10充电接口类型为DCP时，会接收适配器输入的5V、2A的充电功率。
同时，本实施例中，充电控制模块通过硬件系统内部的逻辑电路控制充电电路的电路参数，以适配于适配器所输出的电流。由于在充电开始后，电子设备10内的充电电路与适配器连接形成通路，所以通过调节充电电路的电路参数能够调节适配器的输出。
具体的，本实施例中是通过设置充电输入电流、充电电流、截止电流等一系列所期望达到的充电电流和/或充电电压，进而硬件系统内部的逻辑控制电路根据这些参数以调节充电电路的电路参数。
在下一步骤中，步骤S22，检测适配器是否为PD适配器。
请参阅上PD充电方案部分中关于检测适配器是否为PD适配器的方法。根据适配器是否为PD适配器的检测结果有两种。以下实施例中，先阐述第一种情况：
步骤S23，当适配器为PD适配器时，获取电子设备10当前的电池电压；
具体的，可以通过读取电池保护板上的电压测量电路的测量值以获取当前的电池电压。
步骤S24，根据当前的电池电压，运行PD充电控制脚本。
在本实施例中，当运行PD充电控制脚本时，即进入了特定的PD充电线程。进而根据PD充电线程内的步骤，发送特定的PD充电参数PD参数至适配器，以从PD适配器获取相应的充电功率。
当检测到适配器为特定的PD适配器时，可以通过函数指针的方式跳转到该电子设备10内保存在应用处理器内的充电芯片文件。在该文件内包括写入有电子设备10所特有的PD充电函数。
PD充电控制脚本可以是根据电子设备10硬件系统所支持的充电参数预设在该电子设备10内的。也可以是在电子设备10出厂后通过厂家或用户自行设置的。
不同的硬件系统所支持的充电参数时不同的，因此对应于每个电子设备10内的PD充电控制脚本内的具体充电控制参数会有相应的不同。
具体的，在该PD充电控制脚本运行时，至少进行以下步骤：
在当前的电池电压小于或等于第一电压阈值时，PD充电控制脚本运行时包括以下步骤：
步骤S241，根据PD适配器所支持的充电参数以及电子设备10所支持的充电参数，设置第一PD充电参数，以第一PD充电参数为电子设备10充电。
当检测到适配器为PD适配器时，适配器与电子设备10之间的充电流程会按照PD充电协议进行，按照PD协议，PD适配器会将其支持的所有电压和电流对列表发送至电子设备10一端，因此，电子设备10一端将从该列表中选择具体的一个电压和电流对，选择原则前提是电子设备10的硬件系统必须支持该充电电压和充电电流，而具体选择的哪一组电压和电流对，可以是根据对用户快速充电的配置，也可以是所能获得的最高充电功率。
在此，若电子设备10内电池在开始充电时，已经具有较高的电压，因此在利用根据PD充电方式充电时，会造成电压上升较快，容易造成电池发热量较大。因此本实施例中，通过设置第一电压阈值以保证在充电过程中的安全性。在当前的充电电压小于或等于第一电压阈值时，设置第一PD充电参数，并将第一PD充电参数发送至适配器，用于从适配器获取以第一PD充电参数配置的充电功率。
在此以适配器类型为DCP为例说明，在充电主线程内检测到电子设备10充电接口类型为DCP时，会接收适配器输入的5V、2A的充电功率。在主充电线程中再进一步适配器是否为PD适配器，当适配器为PD适配器时，且电压小于预设的9V时，会跳转到特定的PD充电线程中，执行PD充电线程中的相关步骤。
可以理解的是，PD充电控制脚本的运行大体是基于PD充电协议的，因此关于电子设备10与PD适配器之间的信息交互过程可以参考上述PD充电方案部分。
在PD充电线程中，当PD适配器响应电子设备10所发出的充电参数时，会调节输出电压、输出电流，以为电子设备10的电池供电。然而PD适配器调节其充电电压、充电电流至第一充电参数需要一定的时间。而在这个时间过程中，电子设备10无法获知PD适配器何时能够完成充电电压、充电电流的切换，从而无法调节充电电路的电路参数，以适应PD适配器输出的充电电流，从而容易造成充电电路的电路参数与PD适配器输出的电能不匹配而造成电子设备10从PD适配器吸取过大电流，造成PD适配器输出的充电电流超过其额定值而出发过流保护。
并且，当若是使用的是非正规PD适配器，或是PD适配器对电子设备10请求的充电参数具有较大的兼容性，造成PD适配器没有完全按照电子设备10所发送的第一充电参数进行充电电压、充电电流进行输出，因此导致充电电路根据第一充电参数所调节的充电电路的电路参数与PD适配器实际的输出电压、充电电流不匹配，从而导致充电速度过慢或充电安全性威胁。
因此请参阅图4，本实施例中，在PD充电线程内，根据PD适配器所支持的充电参数以及电子设备10所支持的充电参数，设置第一PD充电参数，用于从PD适配器获取以第一PD充电参数配置的充电功率的步骤之后还包括：
步骤S242，监控PD适配器的输出电压；
步骤S25，当PD适配器的输出电压调整至与第一PD充电参数匹配的电压值时，调整充电电路的电路参数，用于匹配根据第一PD充电参数配置的充电电流。
在本实施例中，单独开辟了一条线程用于检测PD适配器的输出电压的跳变。例如电 子设备10向PD适配器以第一充电参数向适配器请求，通过监控当前的充电总线Vbus上的电压，以监控PD适配器的输出电压发生跳变的时刻。
例如电子设备10在主充电线程内设置的充电参数开始为5V，2A，在进入到PD充电线程内后，电子设备10设置第一充电参数为9V，2A向PD适配器申请。之后电子设备10便监控PD适配器的输出电压从5V跳变到9V的时间点。
一旦监控到PD适配器的输出电压从5V跳变到9V的时间点后，便会调整充电电路的电路参电子设备10内的充电电路参数，以用于自适应以第一PD充电参数配置的充电功率，以保障充电过程的稳定、安全的进行。
在此需要说明的是，在“当前的充电电压调整至与第一PD充电参数匹配的电压值时”PD适配器响应于第一PD充电参数的请求所做的充电电压、充电电流的调整。不仅仅是PD适配器的输出电压与第一PD充电参数中的充电电压相同的情况，还包括由于PD适配器无法输出与第一PD充电参数对应的充电电压、充电电流，而自动选择某一充电参数以替代第一PD充电参数，以输出充电功率的情况。
由此本实施例实现了能够灵活的根据PD适配器实际的输出电压、充电电流调节充电电路的电路参数，并且能够在PD适配器的输出电压发生跳变时，及时的进行充电电路的电路参数的调整，从而保证充电电路的电路参数与PD适配器的输出电压能够很好的配合，保证充电过程的稳定、安全的进行；
并且，通过本实施例的自适应机制，能够根据PD适配器输出电压的调整充电电路的电路参数，以避免发生充电电路自适应到错误的电流档位上的情况。
在一实施例中，可以通过线程轮询以监控适配器的输出电压，在本实施例中，为了节约内存的消耗量和所占用的CPU资源，本实施例中方法还包括：当PD适配器的输出电压调整至与第一PD充电参数匹配的电压值时，触发产生第一中断信号；
监控PD适配器的输出电压包括：监控第一中断信号的出现；当PD适配器的输出电压调整至与第一PD充电参数匹配的电压值时，触发产生第一中断信号；当监控到第一中断信号时，调整充电电路的电路参数，用于匹配根据第一PD充电参数配置的充电电流。
例如，当适配器的输出电压从5V调整至9V时，会自动触发第一中断信号。进而会跳转到步骤：调整充电电路的电路参数，用于自适应以第一PD充电参数配置的充电电流进行。
在本实施例中，为了节约内存的消耗量和所占用的CPU资源，设置在电池电压满足条件下，PD充电线程只执行一次。具体的，仅在本次充电过程中的首次运行充电控制方法时执行。本实施例中设置，根据当前的电池电压，运行PD充电控制脚本为电子设备充电之后还包括：当已执行过一次PD充电控制脚本后，则以第一PD充电参数为电子设备充电；每隔预设时长监视充电电路参数调整指令的接收情况；当接收到充电电路参数调整指令时，根据充电参数调整指令，调整充电电路的电路参数。
当电子设备10向申请到以第一PD充电参数配置的充电功率后，适配器便会按照该充电功率向电子设备10供电。在一具体示例中，当已执行过一次PD充电控制脚本后，会作相应的标记，从而在下一次运行该充电控制方法时，不会再执行PD充电控制脚本。
本实施例中，当电子设备10在某些情况下需要调整充电电流时，为了使充电电路的电路参数能够与当前的充电电流随时保持匹配状态，因此本实施例中，设置每次充电电流调整时，均会对充电电路的电路参数做相应的调整。
具体的，当PD充电控制脚本被标记时，表示PD充电控制脚本已经执行过一次，此时适配器已经是按照第一PD充电参数配置的充电功率输出。然而电子设备10能够自行调节充电电流的大小。所以当电子设备10处于某些特殊的场景下，调节了充电电流后，便会生成充电电路参数调整指令。
可以理解的是，有多种场景可以触发充电电路参数调整指令的生成，例如电子设备 10屏幕点亮、熄灭、打电话等操作时，这些操作均会影响充电电流的大小。
在上述实施例中，阐述了在当前的电池电压小于或等于第一电压阈值，PD充电控制脚本所运行的步骤。而随着充电的进行，当电池电压接近额定电压时，会发生电压虚高而无法被完全充满的情况。因此请参阅图5，在本实施例中，设置在当前的电池电压大于第一电压阈值时，PD充电控制脚本运行时包括以下步骤：
步骤S242，根据PD适配器所支持的充电参数以及电子设备10所支持的充电参数，设置第二PD充电参数，以第二PD充电参数为电子设备充电。
其中，以第二PD充电参数配置的适配器的输出电压小于以第一PD充电参数配置的适配器的输出电压。
在PD充电线程内，在获取到的当前电池电压大于第一电压阈值时，表明电池的电压已经较高，需要使用小电流、小电压进行充电。因此此时电子设备10以具有较小充电功率的第二PD充电参数发送给PD适配器，以使PD适配器输出较小的充电功率，以避免电池电压虚高而无法被充满的现象。
同样的，在电子设备10向PD适配器发出第二PD充电参数后，PD适配器在调节充电功率以第一PD充电参数输出调节到第二PD充电参数输出时，电子设备10无法获知PD适配器何时能够完成充电电压、充电电流的切换，从而无法调节充电电路的电路参数，以适应PD适配器输出的充电电流，从而容易造成充电电路的电路参数与PD适配器输出的电能不匹配而造成电子设备10从PD适配器吸取过大电流，造成PD适配器输出的充电电流超过其额定值而出发过流保护。
因此本实施例中设置在PD充电线程内，根据PD适配器所支持的充电参数以及电子设备10所支持的充电参数，设置第二PD充电参数，以第二PD充电参数为电子设备10充电的步骤之后还包括：监控PD适配器的输出电压；根据PD适配器输出电压的结果会跳转到主充电线程内，根据PD充电控制脚本，从PD适配器获取充电功率之后还包括：当PD适配器输出的输出电压调整至与第二PD充电参数匹配的电压值时，调整充电电路的电路参数，用于匹配根据第二PD充电参数配置的充电电流。
具体的，例如第一PD充电参数为9V，2A，第二PD充电参数为5V，2A，因此当电子设备10发送第二充电参数给PD适配器后，之后电子设备10便监控PD适配器的输出电压从9V跳变到5V的时间点。
一旦监控到PD适配器的输出电压从9V跳变到5V的时间点后，调整充电电路的电路参电子设备10内的充电电路参数，以用于自适应以第一PD充电参数配置的充电功率，以保障充电过程的稳定、安全的进行。
请参阅图6，在上述实施例中，阐述了当适配器为PD适配器时的情况，在此将阐述当适配器不是PD适配器的情况。具体的，检测适配器是否为PD适配器之后还包括以下步骤：
步骤S26，当适配器为不是PD适配器时，每隔预设时长监测充电电路参数调整指令的接收情况；
步骤S27，当接收到充电电路参数调整指令时，根据充电参数调整指令，调整充电电路的电路参数。
具体的，当适配器不是PD适配器时，此时充电控制方法继续按照主充电线程中的步骤继续执行。考虑到当电子设备10处于某些特殊的场景下，会对充电电流进行调节，当电子设备10调节了充电电流时便会生成充电电路参数调整指令。
可以理解的是，有多种场景可以触发充电电路参数调整指令的生成，例如电子设备10屏幕点亮、熄灭、打电话等操作时，这些操作均会影响充电电流的大小。
本公开实施例通过在适用于各种电子设备10硬件环境的主充电线程内设置供调用的PD充电控制脚本的接口，且该PD充电控制脚本具有针对电子设备10自身硬件环境的特 异性。因此在检测到PD适配器为供电设备时，通过调用PD充电控制脚本，以使电子设备10能够基于PD充电协议被快速充电。本公开充电控制方法通过将适用于各种电子设备10硬件环境的充电步骤与具有特异性的PD充电步骤分离开来，使得本方法均可以应用于各种硬件环境的电子设备10内，因此本公开的充电控制方法具有较好的通用性。
