具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
下面参考附图来描述本发明实施例的充电系统、终端、电源适配器和充电线。
图1是根据本发明实施例的充电系统的方框示意图。如图1所示，该充电系统包括：终端100和电源适配器200。
其中，终端100包括第一控制器110和M个充电输入接口。电源适配器200包括第二控制器210和N个充电输出接口，当N个充电输出接口中的至少一个连接到终端100的充电输入接口时，第二控制器210与第一控制器110之间进行相互通信以判断电源适配器200连接到终端100的充电输出接口数量，并根据电源适配器200连接到终端100的充电输出接口数量对电源适配器200输出至终端100的充电电流进行调节，其中，M和N均为大于1的整数。
具体地，可以通过提高电源适配器200输出至终端100的充电电流来实现终端100的快速充电，但是，在对充电电流进行提高时，还需考虑电源适配器200的充电输出接口以及终端100的充电输入接口是否均能满足充电电流的要求。通常情况下，单个充电输入输出接口(例如USB接口)的过电流能力是有限的，如果不解决该问题，则很难对充电电流进行提高。
为此，在本发明的实施例中，可以在终端100上设置多个充电输入接口，并在电源适配器200上设置多个充电输出接口。当需要快速充电时，可以将终端100的多个充电输入接口与电源适配器200的多个充电输出接口相连，然后，根据电源适配器200连接到终端100的充电输出接口数量对电源适配器200输出至终端100的充电电流进行调节，使得电源适配器200可以通过多个接口给终端100进行充电，从而有效提高充电电流，达到快速充电的目的。
根据本发明的一个实施例，如果电源适配器200连接到终端100的充电输出接口数量为k，则将电源适配器200输出至终端100的充电电流调节至k倍的预设充电电流，其中，k为大于等于1的整数。
具体而言，假设每个充电输入接口和充电输出接口的过流能力都相同，且对应的充电电流为预设充电电流，那么当电源适配器200连接到终端100的充电输出接口数量为k时，电源适配器200输出至终端100的充电电流可以提高至k倍的预设充电电流。
例如，当终端100的一个充电输入接口与电源适配器200的一个充电输出接口相连时，充电电流为1倍的预设充电电流；当终端100的两个充电输入接口与电源适配器200的两个充电输出接口相连时，充电电流为两倍的预设充电电流，其中，每个接口对应1倍的预设充电电流，以此类推。由于该系统通过多个充电输入输出接口对终端进行充电，因而能够有效解决由于单个充电输入输出接口的过流能力有限导致的充电电流无法提升的问题，从而解决了快速充电的问题。
进一步地，在本发明的实施例中，可以通过第一控制器110或者第二控制器210对连 接到终端100的充电输出接口数量进行判断。
根据本发明的一个实施例，第二控制器210用于判断电源适配器200连接到终端100的充电输出接口数量，并根据电源适配器200连接到终端100的充电输出接口数量对电源适配器200输出至终端100的充电电流进行调节。
具体而言，当电源适配器200开启充电功能时，第二控制器210可以依次发送预设信号至各个充电输出接口，如果接收到第一控制器110反馈的信号，则说明该充电输出接口与终端100的充电输入接口相连，第二控制器210记录所有连接到终端100的充电输出接口数量，然后根据充电输出接口数量对充电电流进行调节。
根据本发明的另一个实施例，第一控制器110用于判断电源适配器200连接到终端100的充电输出接口数量，并根据电源适配器200连接到终端100的充电输出接口数量通过第二控制器210对电源适配器200输出至终端100的充电电流进行调节。
具体而言，当终端100开启充电功能时，第一控制器110可以依次发送预设信号至各个充电输入接口，如果接收到第二控制器210反馈的信号，则说明该充电输入接口与电源适配器200的充电输出接口相连，第一控制器110记录所有连接到终端100的充电输出接口数量，然后将充电输出接口数量发送至第二控制器210，以使第二控制器210根据充电输出接口数量对充电电流进行调节。
根据本发明的一个实施例，如图2和图3所示，上述的充电系统还包括：充电线300，充电线300的一端包括与M个充电输入接口相匹配的M个第一接口，充电线300的另一端包括与N个充电输出接口相匹配的N个第二接口，电源适配器200的充电输出接口通过充电线300连接到终端100的充电输入接口。
具体地，如图2所示，当用户不需要快速充电时，可以将充电线300的第一接口1与充电输入接口1相连，并将第二接口1和充电输出接口1相连，此时电源适配器200输出至终端100的充电电流为1倍的预设充电电流。
如图3所示，当用户需要快速充电时，可以将充电线300的第一接口1和第二接口2分别与充电输入接口1和充电输入接口2相连，并将充电线300的第二接口1和第二接口2分别与充电输出接口1和充电输出接口2相连，此时电源适配器200输出至终端100的充电电流为2倍的预设充电电流。
其中，M个充电输入接口、M个第一接口、N个第二接口和N个充电输出接口中的每个接口均可为USB接口。
进一步地，根据本发明的一个实施例，M个充电输入接口中的每个充电输入接口通过上拉电阻与预设电源相连，且M个第一接口中的每个第一接口通过下拉电阻接地；N个充电输出接口中的每个充电输出接口通过上拉电阻与预设电源相连，且N个第二接口中的每个 第二接口通过下拉电阻接地，其中，根据每个充电输入接口的电压和每个充电输出接口的电压判断电源适配器连接到终端的充电输出接口数量。
具体地，如图4a所示，充电输出接口和第二接口可以为USB接口(VBUS为电源端，GND为地端，D+和D-为数据端)，其中，充电输出接口通过上拉电阻Rs与预设电源VCC(电压可以为3.3V)相连，第二接口通过下拉电阻Rx后接地。第二控制器210通过实时检测电压检测端的电压，即USB接口的电压来判断充电输出接口是否与第二接口相连。其中，当第二控制器210检测到的USB接口的电压为3.3V时，充电输出接口没有和第二接口相连；如图4b所示，当第二控制器210检测到的USB接口的电压小于3.3V时，充电输出接口与第二接口相连。通过该方式，第二控制器210可以自动检测出是否有充电输出接口与第二接口相连，以及连接的数量。
同样地，通过上述方式，第一控制器110也可以自动检测出是否有充电输入接口与第一接口相连，以及连接的数量。然后，第一控制器110与第二控制器210进行通信，以确定电源适配器200连接到终端100的充电输出接口数量。例如，可以以检测的较小的连接数量作为最终的充电输出接口数量，也可以通过第一控制器110与第二控制器210通过充电线300进行通信，以确定充电输出接口数量，从而防止与其它设备互联时造成充电输出接口数量出现错误。
需要说明的是，在本发明的实施例中，充电线300可以为一个线束，该线束由多根单体连接线构成，每个单体连接线的一端均连接有一个第一接口和一个第二接口；或者，充电线300由一根连接线、一个第一接口和一个第二接口构成，当需要快速充电时，可以使用多根充电线将电源适配器与终端相连。
综上所述，根据本发明实施例的充电系统，终端包括第一控制器和M个充电输入接口，电源适配器包括第二控制器和N个充电输出接口，其中，当N个充电输出接口中的至少一个连接到终端的充电输入接口时，第二控制器与第一控制器之间进行相互通信以判断电源适配器连接到终端的充电输出接口数量，并根据电源适配器连接到终端的充电输出接口数量对电源适配器输出至终端的充电电流进行调节。该系统通过多个充电输入输出接口对终端进行充电，能够有效解决由于单个充电输入输出接口的过流能力有限导致的充电电流无法提升的问题，从而解决快速充电的问题。
图5是根据本发明实施例的终端的方框示意图。如图5所示，该终端100包括：M个充电输入接口、第一控制器110和电池120。
其中，第一控制器110分别与M个充电输入接口和电池120相连，第一控制器110用于在电源适配器的N个充电输出接口中的至少一个连接到充电输入接口时，判断电源适配器连接到充电输入接口的充电输出接口数量，并根据电源适配器连接到充电输入接口的充 电输出接口数量通过电源适配器对电源适配器输出至电池120的充电电流进行调节。其中，M和N均为大于1的整数。
具体地，可以在终端100上设置多个充电输入接口，当需要快速充电时，可以将多个充电输入接口与电源适配器的多个充电输出接口相连，然后，第一控制器110判断连接到充电输入接口的充电输出接口数量，并将该数量发送至电源适配器，以使电源适配器根据该数量对输出至电池120的充电电流进行调节。
根据本发明的一个实施例，如果电源适配器连接到充电输入接口的充电输出接口数量为k，第一控制器110则通过电源适配器将电源适配器输出至电池120的充电电流调节至k倍的预设充电电流，其中，k为大于等于1的整数。
具体而言，假设每个充电输入接口和充电输出接口的过流能力都相同，且对应的充电电流为预设充电电流，那么当电源适配器连接到充电输入接口的充电输出接口数量为k时，电源适配器输出至电池120的充电电流可以提高至k倍的预设充电电流。
例如，当终端100的一个充电输入接口与电源适配器的一个充电输出接口相连时，充电电流为1倍的预设充电电流；当终端100的两个充电输入接口与电源适配器的两个充电输出接口相连时，充电电流为两倍的预设充电电流，其中，每个接口对应1倍的预设充电电流，以此类推。由于该终端通过多个充电输入接口对电池进行充电，因而能够有效解决由于单个充电输入接口的过流能力有限导致的充电电流无法提升的问题，从而解决了终端快速充电的问题。
根据本发明的一个实施例，M个充电输入接口中的每个充电输入接口通过上拉电阻与预设电源相连，第一控制器110根据每个充电输入接口的电压判断电源适配器连接到充电输入接口的充电输出接口数量。其中，M个充电输入接口可以为USB接口。
具体地，如图6a所示，充电输入接口和充电输出接口可以为USB接口，其中，终端100的充电输入接口通过上拉电阻Rs与预设电源VCC(电压可以为3.3V)相连，同时电源适配器的充电输出接口通过下拉电阻Rx与地相连，第一控制器110通过检测电压检测端的电压来判断连接到充电输入接口的充电输出接口数量。其中，当第一控制器110检测的电压为3.3V时，充电输入接口与充电输出接口不相连；如图6b所示，当第一控制器110检测的电压小于3.3V时，充电输入接口与充电输出接口相连。通过该方式，第一控制器110可以自动检测出是否有充电输出接口与充电输入接口相连，以及连接的数量。
可以理解的是，在本发明的实施例中，电源适配器也可以通过充电线与终端的充电输入接口相连，具体可参考图4a和图4b，这里不再详述。
在实际应用中，M个充电输入接口均可以焊接在柔性电路板上，再通过板对板连接器连接到第一控制器110上。
另外，需要说明的是，在本发明实施例中未披露的细节可参见本发明实施例的充电系统中所描述的内容，这里不再赘述。
根据本发明实施例的终端，第一控制器分别与M个充电输入接口和电池相连，第一控制器在电源适配器的N个充电输出接口中的至少一个连接到充电输入接口时，判断电源适配器连接到充电输入接口的充电输出接口数量，并根据电源适配器连接到充电输入接口的充电输出接口数量通过电源适配器对电源适配器输出至电池的充电电流进行调节。该终端通过多个充电输入接口对电池进行充电，能够有效解决由于单个充电输入接口的过流能力有限导致的充电电流无法提升的问题，从而解决了终端的快速充电问题。
图7是根据本发明实施例的电源适配器的结构示意图。如图7所示，该电源适配器200包括：N个充电输出接口、第二控制器210和电源模块220。
其中，第二控制器210分别与电源模块220和N个充电输出接口相连，第二控制器210用于在N个充电输出接口中的至少一个连接到终端的充电输入接口时，判断连接到终端的充电输出接口数量，并根据连接到终端的充电输出接口数量对电源模块220输出至终端的充电电流进行调节，其中，N为大于1的整数。
具体地，可以在电源适配器200上设置多个充电输出接口，当需要快速充电时，可以将终端的多个充电输入接口与电源适配器200的多个充电输出接口相连。然后，第二控制器210判断连接到终端的充电输出接口数量，并根据该数量对电源模块220输出至终端的充电电流进行调节。
根据本发明的一个实施例，如果连接到终端的充电输出接口数量为k，第二控制器210则将电源模块220输出至终端的充电电流调节至k倍的预设充电电流，其中，k为大于等于1的整数。
具体而言，假设每个充电输入接口和充电输出接口的过流能力都相同，且对应的充电电流为预设充电电流，那么当连接到终端的充电输出接口数量为k时，电源模块220输出至终端的充电电流可以提高至k倍的预设充电电流。
例如，当终端的一个充电输入接口与电源适配器200的一个充电输出接口相连时，充电电流为1倍的预设充电电流；当终端的两个充电输入接口与电源适配器200的两个充电输出接口相连时，充电电流为两倍的预设充电电流，其中，每个接口对应1倍的预设充电电流，以此类推。由于该电源适配器通过多个充电输出接口对终端进行充电，因而能够有效解决由于单个充电输出接口的过流能力有限导致的充电电流无法提升的问题，从而解决了快速充电的问题。
根据本发明的一个实施例，N个充电输出接口中的每个充电输出接口通过上拉电阻与预设电源相连，第二控制器210根据每个充电输出接口的电压判断连接到终端的充电输出接 口数量。其中，N个充电输出接口可以为USB接口。
具体地，充电输入接口和充电输出接口可以为USB接口，其中，电源适配器200的充电输出接口通过上拉电阻Rs与预设电源VCC(电压可以为3.3V)相连，同时终端的充电输入接口通过下拉电阻Rx与地相连，第二控制器210通过检测电压检测端的电压来判断连接到充电输入接口的充电输出接口数量。其中，当第二控制器210检测的电压为3.3V时，充电输入接口与充电输出接口不相连；当第二控制器210检测的电压小于3.3V时，充电输入接口与充电输出接口相连。通过该方式，第二控制器210可以自动检测出是否有充电输出接口与充电输入接口相连，以及连接的数量。具体可参考图6a和图6b。
可以理解的是，在本发明的实施例中，电源适配器也可以通过充电线与终端的充电输入接口相连，具体这里不再详述。
另外，需要说明的是，在本发明实施例中未披露的细节可参见本发明实施例的充电系统中所描述的内容，这里不再赘述。
根据本发明实施例的电源适配器，第二控制器分别与电源模块和N个充电输出接口相连，第二控制器在N个充电输出接口中的至少一个连接到终端的充电输入接口时，判断连接到终端的充电输出接口数量，并根据连接到终端的充电输出接口数量对电源模块输出至终端的充电电流进行调节。该电源适配器通过多个充电输出接口给终端进行供电，能够有效解决由于单个充电输出接口的过流能力有限导致的充电电流无法提升的问题，从而解决了快速充电的问题。
图8是根据本发明实施例的充电线的结构示意图。如图8所示，该充电线包括：连接线310、M个第一接口和N个第二接口。
其中，M个第一接口与连接线310的一端相连，且M个第一接口与终端的充电输入接口匹配设置。N个第二接口与所述连接线的另一端相连，且N个第二接口与电源适配器的充电输出接口匹配设置，M和N均为大于1的整数。
具体地，如图2所示，当用户不需要快速充电时，可以将充电线的第一接口1与充电输入接口1相连，并将第二接口1和充电输出接口1相连，此时电源适配器通过充电线输出至终端的充电电流为1倍的预设充电电流。
如图3所示，当用户需要快速充电时，可以将充电线的第一接口1和第二接口2分别与充电输入接口1和充电输入接口2相连，并将充电线的第二接口1和第二接口2分别与充电输出接口1和充电输出接口2相连，此时电源适配器通过充电线输出至终端的充电电流为2倍的预设充电电流。由于该充电线具有多个第一接口和第二接口，因而可以电源适配器可以通过多个第一接口和第二接口对终端进行充电，使得充电电流得以提高，有效解决了因充电线的每一端仅有一个接口导致的充电电流无法提升的问题。
需要说明的是，在本发明的实施例中，连接线310可以为一个线束，该线束由多根单体连接线构成，每个单体连接线的一端均连接有一个第一接口和一个第二接口；或者，充电线由一个连接线310、一个第一接口和一个第二接口构成，当需要快速充电时，可以使用多根充电线将电源适配器与终端相连。
根据本发明的一个实施例，M个第一接口中的每个第一接口通过下拉电阻接地，且N个第二接口中的每个第二接口通过下拉电阻接地。其中，M个第一接口和N个第二接口均可以为USB接口。
具体地，M个第一接口、N个第二接口、终端的充电输入接口和电源适配器的充电输出接口中的每个接口均可为USB接口。如图4a所示，电源适配器的充电输出接口可通过上拉电阻Rs与预设电源VCC(电压可以为3.3V)相连，充电线的第二接口可通过下拉电阻Rx后接地。此时电源适配器可通过实时检测电压检测端的电压，即USB接口的电压来判断充电输出接口是否与第二接口相连。其中，当电源适配器检测到的USB接口的电压为3.3V时，充电输出接口没有和第二接口相连；如图4b所示，当电源适配器检测到的USB接口的电压小于3.3V时，充电输出接口与第二接口相连。通过该方式，电源适配器可以自动检测出是否有充电输出接口与第二接口相连，以及连接的数量。
同样地，终端的充电输入接口可通过上拉电阻Rs与预设电源VCC(电压可以为3.3V)相连，充电线的第一接口可通过下拉电阻Rx后接地。此时终端可通过实时检测电压检测端的电压，即USB接口的电压来判断充电输入接口是否与第一接口相连。其中，当终端检测到的USB接口的电压为3.3V时，充电输入接口没有和第一接口相连；当终端检测到的USB接口的电压小于3.3V时，充电输入接口与第一接口相连。通过该方式，终端可以自动检测出是否有充电输入接口与第一接口相连，以及连接的数量。
然后，电源适配器与终端进行通信，以确定电源适配器通过充电线连接到终端的充电输出接口数量，最后根据连接到终端的充电输出接口数量对电源适配器输出至终端的充电电流进行调节，以实现快速充电的目的。
另外，需要说明的是，在本发明实施例中未披露的细节可参见本发明实施例的充电系统中所描述的内容，这里不再赘述。
根据本发明实施例的充电线，连接线的一端具有M个第一接口，连接线的另一端具有N个第二接口，并且M个第一接口与终端的充电输入接口匹配设置，N个第二接口与电源适配器的充电输出接口匹配设置，从而可以使电源适配器的多个充电输出接口能够同时与终端的多个充电输入接口相连，以便电源适配器通过多个充电输入输出接口对终端进行充电，有效解决了当充电线的两端均只有一个接口时，而该接口的过流能力有限导致的充电电流无法提升的问题，从而解决了快速充电的问题。
