Description

充电方法、移动终端和充电装置 技术领域
本发明实施例涉及充电领域，并且更具体地，涉及一种充电方法、移动终端和充电装置。
背景技术
随着移动终端(如手机、pad等)的普及，移动终端的功能不断丰富，同时，移动终端的耗电也越来越严重，因此，如何提高移动终端电池的充电速度越来越受到关注。
有些厂商推出了支持快速充电模式的移动终端，如OPPO的许多款移动终端均支持VOOC闪充技术，快充技术大大缩短了移动终端的充电时间，受到用户的广泛青睐。
为了保证快速充电的安全可靠，一般情况下，适配器和移动终端在进入快速模式之前，需要经历握手协商的过程，通过握手协商可以询问双方是否均支持快充，还可以确定快充的电压、电流等参数。
现有技术中，快充的握手协商过程均是由适配器发起的。适配器会在满足一定条件的情况下发起快充的握手协商过程，但是，该“一定条件”比较难定义，例如，当适配器与移动终端通过充电接口相连时，移动终端需要先识别充电器的类型。如果此时适配器立刻向移动终端发起握手请求信号，会影响移动终端对充电器的类型的识，容易出错；如果适配器过晚发起握手请求信号，会影响移动终端的充电速度。
因此，移动终端和适配器之间到底什么时候、以何种方式发起关于快充的握手协商有待优化。

附图说明
为了更清楚地说明本发明实施例的技术方案，下面将对本发明实施例中所需要使用的附图作简单地介绍，显而易见地，下面所描述的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

图2是握手请求信号的波形的示例图。
图3是本发明实施例的充电方法的示意性流程图。
图4是本发明实施例的移动终端的示意性框图。
图5是本发明实施例的充电装置的示意性框图。
图6是本发明实施例的移动终端的示意性框图。
图7是本发明实施例的充电装置的示意性框图。
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。
应理解，本发明实施例的充电装置可以是适配器或移动电源。
现有技术中，移动终端与充电装置通过充电接口连接后，移动终端首先会去识别充电装置的类型，移动终端在识别出充电装置的类型之后，才会与充电装置进行关于快充的握手协商，但是，充电装置并不知道移动终端什么时候完成充电装置类型的识别过程，握手请求发的过早会造成移动终端识别过程出错，握手请求发的过晚会导致双发不能及时进入快充模式，造成充电过程的延长。换句话说，移动终端最清楚充电装置类型的识别过程什么时候结束，因此，由移动终端作为握手请求的发起方最为合适。此外，移动终端对充电装置的类型识别是利用充电装置通过D-线上发送的电平信号实现的，也就是说，充电接口中的D-数据线始终被充电装置占用，来发送该电平信号。因此，移动终端最好利用D+线与充电装置进行单线通信，完成快充的握手协商，以避开与D-数据线混用。这样，在移动终端和充电装置连接过程中，由移动终端主动发起关于快充的握手请求，充电接口中的D+、D-、电源线各司其职、相互配合，能够很好地解决现有技术中的快充握手协商可能会出错的问题。下面结合图1，详细描述本发明实施例。
图1是本发明实施例的充电方法的示意性流程图。图1的方法包括：
110、在移动终端通过充电接口与充电装置连接的过程中，所述移动终端通过所述充电接口中的D-数据线接收所述充电装置发送的电平信号，以确定所述充电装置的类型。
应理解，上述充电接口可以是通用串行总线(Universal Serial Bus，USB)，也可以是micro USB。
还应理解，上述电平信号可以指示充电装置的充电接口的类型，例如，当充电接口的类型为通用串行总线标准下行端口(Universal Serial Bus_Standard Downstream port，USB_SDP)时，可以认为该充电接口并非充电器，即并非适配器或移动电源，可能是电脑，无法支持大电流充电，此时，无需进行后续的握手协商过程，按照小电流充电即可；当充电接口的类型为非USB_SDP，如通用串行总线专用充电接口(Universal Serial Bus_Dedicated Charger port，USB_DCP)，可以认定该充电装置为适配器或移动电源等专门用于充电的设备。
120、当确定所述充电装置为适配器或移动电源时，所述移动终端通过所述充电接口中的D+数据线，向所述充电装置发送握手请求信号，所述握手请求信号用于询问所述充电装置是否支持快速充电模式。
握手请求信号可以是通过协议预先规定的，该握手请求信号可以具有特定的波形。图2示出了特定波形的一个示例，D+输出低电平，移动终端按照图2所示的时序发送特定波形的握手请求信号。此时，充电装置可以按照特定时序接收该特定形式的波形，例如，充电装置的接收时序可以是：收到上升沿中断后，延时2nms采集数据，这样，图2所示的波形解析出来的数据为01010101…。
130、所述移动终端接收所述充电装置发送的握手响应信号，所述握手响应信号用于指示所述充电装置支持快速充电模式。
例如，充电装置解析出的数据与预先协商的数据一致，也可以通过D+按照特定的波形(或特定的数据)发送至移动终端，以表示自己支持快速充电模式。
140、所述移动终端进入所述快速充电模式，通过所述充电接口中的电源线从所述充电装置引入所述快速充电模式下的充电电流，为所述移动终端中的电池充电。
应理解，移动终端可以在接收到握手响应信号之后立刻进入快充模式，也可以继续与充电装置协商充电电流、充电电压等参数后再进入快充模式。
上述移动终端进入快速充电模式可以是主动的进入快速充电模式，也可以是被动的进入快速充电模式，例如，移动终端可以不执行任何操作，被动接收充电装置发送的快充电流；或者，移动终端可以主动配置内部的充电芯片的参数，使其与快充模式相匹配，本发明实施例对此不作具体限定。
本发明实施例中，移动终端主动发起关于快充的握手协商过程，且移动终端通过D+数据线与充电装置进行单线握手协商，解决了现有技术中的快充握手协商可能会出错的问题。
可选地，作为一个实施例，图1的方法还可包括：当确定所述充电装置不是适配器或移动电源时，所述移动终端进入普通充电模式，通过所述充电接口中的电源线从所述充电装置引入所述普通充电模式下的充电电流，为所述移动终端中的电池充电，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。

上文结合图1至图2，从移动终端的角度详细描述了根据本发明实施例的充电方法，下文结合图3，从充电装置的角度详细描述根据本发明实施例的充电方法，应理解，移动终端和充电装置是充电过程中相互交互的两个实体，移动终端侧描述的步骤、功能与充电装置侧类似或相应，为了简洁和清楚，适当省略重复的描述。
