目前，为了满足快速充电的要求，有些移动终端(如手机)厂商的电源适配器设计成智能的电源适配器。以Oppo的VOOC闪充为例，其电源适配器的控制核心是微控制单元(Microcontroller Unit，MCU)，在该MCU的控制下，Oppo的电源适配器可以根据当前状态调整自身的工作模式。
众所周知，MCU的特点就是可编程，即通过更改软件代码可以让其实现不同的功能，也只有下载了新的程序的MCU才具备新的功能。因此，为了让MCU成为电源适配器的控制核心，必须要给其下载相应的程序。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明的一部分实施例，而不是全部实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都应属于本发明保护的范围。
目前的电源适配器均不设置有射频模块，无法像移动终端一样，能够通过OTA(over the air)技术方便地下载升级信息，实现升级。为此，本发明实施例利用移动终端下载电源适配器的软件升级信息，并在移动终端和电源适配器连接的过程中，通过移动终端和电源适配器之间的充电接口将下载到的软件升级信息发送至电源适配器的处理器中，以便电源适配器的处理器利用该软件升级信息进行升级。下文结合具体的实施例，详细描述本发明实施例的电源适配器的升级方法。
图1是本发明实施例的电源适配器的升级方法的示意性流程图。图1的方法包括：
110、移动终端下载所述电源适配器的软件升级信息，所述软件升级信息用于升级所述电源适配器的软件。
应理解，本发明实施例对电源适配器的软件升级信息的具体形式不作限定，例如，该软件升级信息可以作为电源适配器内部的处理器的固件(firmware)。
应理解，移动终端可以是手机、pad等。
应理解，移动终端可以包括应用处理器(Application Processor，AP)和MCU(如基带处理器)，其中，移动终端的AP可以负责智能终端相关的功能，如APP的下载与管理；移动终端的MCU可以负责一些基本功能，如短信、通话功能。所述软件升级信息可以是由所述移动终端中的AP通过射频模块从网络中下载到的信息。例如，AP通过蜂窝网或者WIFI等下载软件升 级信息。
120、在所述移动终端通过充电接口与所述电源适配器连接的过程中，所述移动终端通过所述充电接口中的数据线，向所述电源适配器的处理器发送所述软件升级信息，以便所述处理器根据所述软件升级信息，升级所述电源适配器的软件。
本发明实施例中，利用移动终端下载电源适配器的软件升级信息，并在移动终端和电源适配器连接的过程中，将最新的软件升级信息发送至电源适配器，对电源适配器进行升级，解决了电源适配器升级困难的问题。具体地，当电源适配器出现bug，或者适配器的软件进行了升级，就无需返厂维修，直接利用移动终端从网上下载新的软件升级信息即可。
应理解，上述充电接口可以为通用串行总线(Universal Serial Bus，USB)接口，该USB接口可以是正常的USB接口，也可以是micro USB接口。所述充电接口中的数据线为所述USB接口中的D+线和D-线中的至少一根。
还应理解，本发明实施例对电源适配器中的处理器的类型不作具体限定，例如，可以是某种型号的MCU。
目前，在快速充电领域中，电源适配器的处理器的主要接口，如I2C(Inter－Integrated Circuit)口，都被占用，这些接口具有各自需要完成的任务或实现的功能，一般情况下，电源适配器的处理器的通用异步收发传输器(Universal Asynchronous Receiver/Transmitter，UART)接口未被充分利用。那么，要完成电源适配器的升级，可以将上述软件升级信息转换成为UART格式的数据，然后由电源适配器的处理器的UART接口接收该UART格式的数据。本发明实施例对软件升级信息转换成为UART格式数据的具体方式不作限定，具体地，可以由移动终端将所述软件升级信息转换成UART格式的数据；然后，该移动终端通过所述充电接口中的数据线，向所述电源适配器的处理器的UART接口发送所述UART格式的数据。具体地，可以由移动终端的AP完成上述软件升级信息的转换，或者，可以由移动终端的MCU完成上述软件升级信息的转换。下面以移动终端的AP进行软件升级信息的转换为例，进行详细说明。
可选地，作为一个实施例，所述移动终端将所述软件升级信息转换成UART格式的数据，包括：所述移动终端的AP将下载到的所述软件升级信息转换成I2C格式的数据；所述移动终端的AP利用I2C接口，将所述I2C 格式的数据发送至所述移动终端的MCU；所述移动终端的MCU将所述I2C格式的数据转换成所述UART格式的数据，通过所述充电接口中的数据线，向所述电源适配器的处理器的UART接口发送所述UART格式的数据。
本发明实施例中，当移动终端的AP将下载到的软件升级信息通过处理器间的I2C口发送至移动终端的MCU之后，由移动终端的MCU将I2C格式的软件升级信息转换成UART格式的数据，发送至电源适配器，解决了电源适配器专用接口不足的缺陷。此外，现有技术中，移动终端的MCU与适配器的处理器之间建立有通信链路，因此，由移动终端MCU将软件升级信息发送至电源适配器可以沿用现有的通信链路。此外，由移动终端的MCU完成上述格式的转换可以分担AP的负担。
可选地，作为一个实施例，图1的方法还可包括：所述移动终端的MCU向所述电源适配器发送握手请求消息，所述握手请求消息用于询问所述电源适配器当前使用的软件的版本；所述移动终端的MCU接收所述电源适配器发送的握手响应消息，所述握手响应消息包括用于指示所述电源适配器当前使用的软件的版本的信息；所述移动终端的MCU根据所述电源适配器当前使用的软件的版本，以及下载到的所述软件升级信息指示的最新版本，确定所述电源适配器当前使用的软件是否需要升级；所述移动终端的MCU向所述电源适配器的处理器的UART接口发送所述UART格式的数据，包括：当确定所述电源适配器当前使用的软件需要升级时，所述移动终端的MCU向所述电源适配器的处理器的UART接口发送所述UART格式的数据。
应理解，上述握手过程还可以由移动终端的AP执行。
具体地，图1的方法还可包括：所述移动终端的AP通过第一链路，判断插入的供电设备是否为所述电源适配器，其中，所述第一链路连接所述AP的USB接口与所述充电接口；当判断插入的供电设备为电源适配器时，所述移动终端通过USB开关从所述第一链路切换至第二链路，所述第二链路连接所述移动终端的MCU与所述充电接口；所述移动终端的MCU向所述电源适配器的处理器的UART接口发送所述UART格式的数据，包括：所述移动终端的MCU通过所述第二链路，向所述电源适配器的处理器的UART接口发送所述UART格式的数据。
应理解，步骤120中，移动终端可以在充电过程中向电源适配器发送软件升级信息，或者，移动终端可以在充电前或充电后将该软件升级信息发送 至电源适配器处，本发明实施例对此不作具体限定。下面给出一种具体的实现方式。
可选地，作为一个实施例，步骤120可包括：在所述电源适配器采用普通充电模式为所述移动终端充电的过程中，所述移动终端通过所述充电接口中的数据线，向所述电源适配器的处理器发送所述软件升级信息；图1的方法还可包括：当所述电源适配器根据所述软件升级信息升级所述电源适配器的软件后，所述移动终端从所述普通充电模式切换至快速充电模式，其中，所述快速充电模式的充电速度大于所述普通充电模式的充电速度。
本发明实施例中，电源适配器先采用普通充电模式为移动终端进行，并在该普通充电的过程中，移动终端将软件升级信息发送至电源适配器处，当电源适配器完成升级之后，从普通充电模式切换至快速充电模式，这样能够保证电源适配器的及时升级，并保证电源适配器总是采用最新的软件功能为移动终端提供充电服务。
下面结合具体例子，更加详细地描述本发明实施例，在下面的例子中，移动终端为手机，手机包括AP和MCU，电源适配器(以下简称适配器)的处理器为MCU，适配器的软件升级信息为适配器MCU固件，手机通过OTA技术将适配器MCU固件下载到AP中。应注意，图2至图6的例子仅仅是为了帮助本领域技术人员理解本发明实施例，而非要将本发明实施例限于所例示的具体数值或具体场景。本领域技术人员根据所给出的图2至图6的例子，显然可以进行各种等价的修改或变化，这样的修改或变化也落入本发明实施例的范围内。
图2是本发明实施例的电源适配器的升级方法的示意性流程图。图2的方法包括：
201、手机插入供电设备。
202、手机AP判断该供电设备是否为适配器，如果供电设备不是适配器，转到步骤203，如果供电设备时适配器，转到步骤204。
手机包括AP和MCU，手机的AP和MCU均可以与适配器MCU进行通信。具体地，如图3所示，手机内部可以设置一个USB开关，在通道1和通道2之间进行切换，当该USB开关切换至通道1时，手机AP可以通过充电接口的D+/D-与适配器MCU进行通信；当该USB开关切换至通道2时，手机MCU可以通过充电接口的D+/D-与适配器MCU进行通信。USB开关 可以默认打在通道1上，当插入供电设备时，手机AP可以识别其是否为适配器。手机AP识别适配器的通信链路如图4所示。
203、进入非适配器充电模式。
例如，供电设备时电脑，手机插到电脑上，可以利用电脑为手机供电。
204、将手机的USB开关从AP端切换到手机MCU端。
205、手机MCU与适配器MCU完成握手匹配，并询问适配器MCU固件版本号。
具体地，手机MCU与适配器的握手协商过程的通信链路可以如图5所示，此时，USB开关打在通道2上。
206、手机MCU将收到的适配器MCU固件版本号上报给AP。
207、AP判断是否要升级适配器MCU固件，当不需要对适配器MCU固件进行升级时，执行步骤208；当需要对适配器MCU固件进行升级时，执行步骤209。
208、直接进入快充。
209、AP通知手机MCU适配器的固件需要升级。
210、手机MCU在收到AP的需要升级适配器固件的答复后，上报适配器“需要对固件进行升级”。
具体地，参见图6，图6描述的是适配器固件升级时手机AP、手机MCU、适配器MCU之间的通信链路，相当于在MCU与适配器MCU之间直接建立了UART串口连接。
211、适配器MCU在收到手机MCU通知的需要升级的信息后，进入下载模式，将适配器与手机MCU的D+/D-通信口设置为串口，并等待AP传输数据。
212、AP在延时一定时间后，开始向适配器MCU发送I2C格式的数据，手机MCU将I2C格式的数据转换成UART格式的数据，并将该UART格式的数据通过USB接口传到适配器中。
可以预设延迟时间，当延迟时间达到时，AP可以认为手机MCU与适配器MCU都已准备好，开始向适配器MCU发送UART格式的数据。
213、AP发送完I2C数据后，适配器MCU将获取到的数据回传给AP，由AP完成对数据的校验，判断是否升级成功，当判断升级成功时，执行步骤208；当判断升级失败时，执行步骤212。
