Description

一种实现快速充电的方法、装置及系统 技术领域
本发明实施例涉及移动终端应用技术，尤指一种实现快速充电的方法、装置及系统。
背景技术
智能移动终端屏幕越来越大，处理器能力越来越强，因此移动终端对于电量的消耗也越来越多，尽管电池电量也随之增大，但是还是满足不了人们对于工作时间的需求。因为电池技术作为一个非常基础的技术，在很短时间内获得突破和迅速发展是不可能的，因此一些厂商尝试找到一些其他的方法缓解目前的问题，例如为移动终端快速充电就是一个比较常用的解决方法。
目前，为移动终端快速充电的方案大致有两种，充电快慢取决于充电功率，功率等于电压乘以电流，因此实现快速充电的方案可以通过提升充电电压或者加大充电电流来实现。
利用加大电流的快速充电方案中，以苹果的Lightning充电接口为例，相比于业界通用的Micro USB接口，Lightning接口有更多的pin脚可以用于充电，因此可以提供更大的电流。国内的欧珀公司提出了VOOC快速充电方案，此方案在Micro USB接口上增加了两根线用于充电，也是增大了充电的电流。由于苹果产品的封闭性，苹果的方案只能用于苹果自家的产品，其他厂商并不能采用，因此业界无法通用，而欧珀的产品需要定制特殊的数据线用于欧珀的产品，此方案通用性也不足。
而利用提升电压实现快速充电方案中，如高通Quick Charge2.0方案。功率等于电压的平方，再除以电阻，当电压提高的时候，功耗也会随之变大，产生的热能也会增多，因此，充电之时充电器和移动终端都会发热。
因此，需要一种既能和当前Micro USB标准兼容，又可以比较好的快速充电的方案，以满足人们对于快速充电的需求。

本发明实施例提供一种快速充电的方法，如图1所示，包括：
步骤101，移动终端和接入的适配器分别将延伸到充电接口中的信号线切换至与充电线相连；
具体的，该步骤中，移动终端和接入的适配器在进行信号线切换前，移动终端与接入的适配器还需进行功能匹配，以互通是否支持快速充电功能，当二者均支持快速充电功能时，触发信号线切换动作。
其中，移动终端与接入的适配器进行功能匹配的方式包括但不限于为：
移动终端在支持快速充电时，向接入的适配器发送匹配信号；
适配器在支持快速充电时，对接收到的匹配信号进行响应。
也就是说，支持快速充电的移动终端会发送匹配信号，当适配器接收到该匹配信号时，判定移动终端支持快速充电功能。同理，支持快速充电的适配器会对匹配信号进行响应，接收到响应信号的移动终端判定出适配器支持快速充电功能。在能力互通后，即可进行快速充电的相关配置。
进一步地，该步骤中信号线与充电线的连接方式如下：
移动终端将延伸到充电接口中的信号线的一路切换至与充电线中的电源 线相连，另一路切换至与充电线中的地线相连。
同理，适配器将延伸到充电接口中的信号线的一路切换至与充电线中的电源线相连，另一路切换至与充电线中的地线相连。
也就是说，移动终端和适配器将充电数据线中的DATA线临时切换为充电线，合并到原来的充电线路中，加粗充电线路，以提升充电电流。
进一步的，该步骤中，当二者进行功能匹配后发现有一方不支持快速充电功能，则退出本流程，只需按普通充电方式进行充电即可，无需进行线路切换设置。
步骤102，适配器采用设定的高阶功率模式为移动终端充电。
由于步骤101中对充电线路做了加粗处理，所以当前的充电线路可以承载更大的充电电流，此时，适配器切换至设定的高阶功率为移动终端充电，以达到快速充电的效果。
该步骤中，设定的高阶功率的输出的电流可以但不限于为2A。
综上所述，可知本发明所述的快速充电方法利用已有的信号线，加粗充电线路，提高了充电电流，进而实现了快速充电的目的。相比于目前已有的快速充电方法，充电线路有更好的通用性，并且与现有的其他移动终端和充电器都兼容，在使用非匹配的产品时，亦可以实现普通充电功能。
为了更清楚的阐述本发明所述方法的实施过程，下面给出本发明一个较佳的实施例，并结合对实施例的描述，进一步给出本发明的技术细节，使其能够更好地说明本发明提供的方法的具体实现过程。
本实施例中，设移动终端和接入的适配器均支持快速充电功能，二者采用的充电接口为目前较为常用的Micro USB接口，如图2中左侧示出的为适配器侧数据线接口图，图2中右侧示出的为移动终端侧数据线接口图。
本实施例所述方法利用适配器充电时，当与移动终端匹配成功后，二者将D+和D-线路分别合并到Vbus和GND线路中，增大充电线路可通过的最大安全电流值，以实现快速充电，具体操作流程如下：
移动终端侧监测到Micro USB接口Vbus电压值变化，判断移动终端是否进入充电状态；
进入充电状态后，移动终端利用D+和D-信号线向充电适配器发送匹配信 号，适配器侧不断扫描D+和D-信号线，当收到移动终端发来的匹配信号后，向移动终端发送匹配成功信号，移动终端收到适配器返回的成功匹配信号后，匹配成功；
匹配成功后，移动终端将Micro USB接口中的D+信号线与移动终端处理器的数据线断开，与Micro USB接口中Vbus线相连，起到Vbus线线路加粗的功能，Micro USB接口中的D-信号线与移动终端处理器的数据线断开，与Micro USB接口中GND线相连，起到GND线线路加粗的功能；同时，适配器Micro USB接口中的D+信号线与适配器侧处理器的数据线断开，与Micro USB接口中Vbus线相连，起到Vbus线线路加粗的功能，Micro USB接口中的D-信号线与适配器侧处理器的数据线断开，与Micro USB接口中GND线相连，起到GND线线路加粗的功能；
其中，将D+信号线与Vbus线相连，D-信号线与GND相连只是一种连接方式，在设计时，可以将D+信号线与GND线相连，D-信号线与Vbus相连。
进一步地，适配器在进行线路切换后，切换到设定的高阶功率模式，输出额定电流为2A，实现快速充电。然而，若适配器和移动终端在匹配不成功时，即，至少有一方不支持快速充电功能时，适配器按照普通的充电模式充电，即输出额定电流为1A，保证了使用安全。

进一步地，本实施例所述移动终端还包括充电监测模块320和第一功能匹配模块330，用以与第一线路切换模块310配合，实现快速充电。具体的：
充电监测模块320，设置为在监测到适配器接入时，触发第一功能匹配模块330；
第一功能匹配模块330，设置为在移动终端支持快速充电时，向接入的适配器发送匹配信号，并在接收到所述适配器反馈的响应信号时，判定移动终端和接入的适配器均支持快速充电功能，触发第一线路切换模块310。
其中，充电监测模块320具体设置为通过监测充电接口(Micro USB接口)的Vbus电压，判断是否进入充电状态，当进入充电状态判定为适配器接入。
进一步地，本实施例中，第一线路切换模块310，具体设置为将延伸到充电接口中的信号线一路切换至与充电线中的电源线相连，一路切换至与充电线中的地线相连。
示例说明：当移动终端的充电接口为Micro USB接口时，第一线路切换模块320将Micro USB接口中的D+信号线与移动终端处理器的数据线断开，与Micro USB接口中Vbus线相连，起到Vbus线线路加粗的功能，Micro USB接口中的D-信号线与移动终端处理器的数据线断开，与Micro USB接口中GND线相连，起到GND线线路加粗的功能。
实施例三

进一步地，本实施例所述适配器还包括第二功能匹配模块430，用以与第二线路切换模块410配合，实现快速充电。具体的：
第二功能匹配模块430，设置为在接收到移动终端发送的匹配信号时，判定移动终端侧支持快速充电功能，并在所属适配器支持快速充电功能时，对接收到的匹配信号进行响应，触发第二线路切换模块410。
进一步地，本实施例中，第二线路切换模块410，具体设置为将延伸到充电接口的信号线一路切换至与充电线中的电源线相连，一路切换至与充电线中的地线相连。
示例说明：当适配器的充电接口为Micro USB接口时，第二线路切换模块410将Micro USB接口中的D+信号线与适配器的处理器的数据线断开，与Micro USB接口中Vbus线相连，起到Vbus线线路加粗的功能，Micro USB接口中的D-信号线与适配器的处理器的数据线断开，与Micro USB接口中GND线相连，起到GND线线路加粗的功能
