具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
为了更加清楚地理解本申请，以下先简单介绍下快速充电的方式以及工作原理，便于后续理解本申请的方案。但应理解，以下介绍的内容仅仅是为了更好的理解本申请，不应对本申请造成特别限定。
目前快充技术一般采用的是高压快充方式或大电流方式。
其中，高压快充方式是电源提供装置向电子设备输入高于5V的电压，例如，以电压为9V、电流为2A的充电功率对电子设备进行充电，电子设备内部再对将电压转换至5V后输入电池，此时进入电池的电流大概为3.6A。
大电流方式是直接以大电流对电子设备的电池进行充电，例如，以电压为5V、电流为4A的充电功率对电池进行充电，不需要电子设备内部再进行降压转换。
总的来说，在快充过程中，对电池来说都是需要将充电电流提升后加快充电速度，换句话说，可以将电池的充电倍率从0.7C提升至1.5C甚至3.0C。其中C为充电倍率，例如，对于容量值为3000mAh的电池来说，1.5C的充电电流为4.5A，3.0C的充电电流为9.0A。
以锂离子电池为例，一般来说，充电速度的提升不会影响到电池的使用寿命，这是因为在对电池开发设计时，会对电池内部的结构、极片面密度、隔膜的孔隙率以及正负极和导电剂等结构进行改进，从而能够加快锂离子在正负极间的传输速度，达到提升充电倍率的作用。因而提升充电速度后可能不会对电池的循环寿命带来过大的影响。
虽然提升充电速度后不会影响到电池的本体寿命，但是会带来使用过程中的寿命影响。
具体地，在对离子电池充电过程中，随着容量的增加，电池的电压也会不断的提升，根据电池在充电过程中的电化学反应过程，充电时Co 3+不断的被氧化成Co 4+，而Co 4+的氧化性非常高，即容易和电池中的电解液发生化学反应，导致电解液被不断地消耗掉，从而加速电池的老化过程。
在对电子设备进行充电时，若电子设备已经达到高电量或者满充状态，而用户由于外出或其他事情导致不能及时断开对电子设备进行充电，例如，在夜间对电子设备进行充电时，由于用户已经休息而导致的不能及时断开对电子设备的充电，在这种情况下，会导致电解液被不断地消耗掉，从而加速电池的老化过程。
此外，一般来说使用快充模式对电子设备进行充电，由于充电电流的增加，会导致充电过程中电池的温升值增加，当然，正常使用快充模式对电子设备进行充电时不可避免的，但是在没有快充需求的情况下，例如，上述提到的用户在夜间休息时，如果此时使用快充模式对电子设备进行充电，则会造成不必要的高温，进一步地，降低电池的安全。
因此，本申请提供一种充电方法，可以尽量减小在电池已经达到高电量或满充状态的情况下，由于用户不能够及时断开对电子设备的充电所带来的电池老化问题，同时也能够尽量避免不必要的高温而带来的电池安全问题。

应理解，本申请实施例中的数值仅为举例说明，还可以为其他数值，不应对本申请造成特别限定。
本申请实施例提供的充电方法，通过根据电子设备所处环境的光线强度值确定充电模式，即确定充电模式是快充模式还是低于快速充电的充电模式，可以尽量减小在电池已经达到高电量或满充状态的情况下，由于用户不能够及时断开对电子设备的充电所带来的电池老化问题，从而可以延长电池的使用寿命，同时也能够尽量避免不必要的高温而带来的电池安全问题。
可选地，在一些实施例中，所述根据所述光线强度值，确定充电模式，包括：若所述光线强度 值小于或等于第一阈值，确定第一充电模式为所述充电模式；若所述光线强度值大于所述第一阈值，确定第二充电模式为所述充电模式；其中，所述第二充电模式的充电电流大于所述第一充电模式的充电电流。
本申请实施例中，第一充电模式可以为上述提到的低于快速充电的充电模式，第二充电模式可以为上述提到的快速充电模式。
一种实现方式下，光线强度值的单位可以为勒克斯(Lux)。一般情况下，夜间的光线强度为(0.001-0.3)Lux，白天的光线强度为(5-1000)Lux，特别地，对于夏季中午阳光下的光线强度约为10*9次方。
本申请实施例中的第一阈值可以为0.3，即若电子设备所处的光线强度值小于或等于0.3Lux，则可以利用低于快速充电的充电模式对电子设备进行充电；若电子设备所处的光线强度值大于0.3Lux，则可以利用快速充电模式对电子设备进行充电。
基于该实现方式，本申请实施例中的第一阈值还可以为其它数值，例如，0.4或1等，本申请对此不作具体限定。
在另一种实现方式下，光线强度值的单位可以用百分比来表示，例如，第一阈值为5％，若电子设备所处的光线强度值小于或等于5％，则可以利用低于快速充电的充电模式对电子设备进行充电；若电子设备所处的光线强度值大于5％，则可以利用快速充电模式对电子设备进行充电。

上文指出，可以根据电子设备所处环境的光线强度值确定充电模式，但是在一些情况下，室外光线强度值可能大于第一阈值，而室内光线强度值可能小于第一阈值，例如，在白天将窗帘关闭的情况下，此时获取的光线强度可能不是很准确，可能会将本应利用快速充电模式对电子设备进行充电误判为利用低于快速充电的充电模式对电子设备进行充电。因此，可以结合其他因素确定充电模式。
可选地，在一些实施例中，所述方法还包括：获取所述电子设备在所述光线强度值下的持续时长、当前时刻以及所述电子设备当前剩余电量中的至少一种；所述根据所述光线强度值，确定充电模式，包括：根据所述持续时长、所述当前时刻以及所述当前剩余电量中的至少一种，以及所述光线强度值，确定所述充电模式。

例如，该光线强度为0.3Lux，计算在光线强度为0.3Lux下的持续时长；或者，该光线强度为0.001-0.3Lux，计算在光线强度为0.001-0.3Lux下的持续时长。
本申请实施例中的当前时刻为地球时刻，该时刻可以通过本申请中所使用的电子设备所显示的时刻来确定，也可以根据其他设备所显示的时间来确定，例如，电视机、手表等，本申请对此不作具体限定。
本申请实施例中，根据持续时长、当前时刻以及当前剩余电量中的至少一种，以及所述光线强度值，确定所述充电模式，可以为根据光线强度值和持续时长确定充电模式，也可以为根据光线强度值和当前时刻确定充电模式，还可以根据光线强度值和当前剩余电量确定充电模式；或者，可以根据光线强度值和持续时长以及当前时刻确定充电模式，也可以为根据光线强度值和持续时长以及前剩余电量确定充电模式，还可以根据光线强度值和当前时刻以及当前剩余电量确定充电模式；或者，可以根据光线强度值、持续时长、当前时刻以及当前剩余电量确定充电模式。
本申请实施例提供的充电方法，由于在基于光线强度值的基础上结合其他因素共同确定充电模式，因此，可以避免由于在其他因素的影响下导致获取的光线强度值不准确，而导致误判充电模式的问题，即将本应利用快速充电模式对电子设备进行充电误判为利用低于快速充电的充电模式对电 子设备进行充电或将本应利用低于快速充电的充电模式对电子设备进行充电误判为利用快速充电模式对电子设备。
上文指出，可以根据持续时长、当前时刻以及当前剩余电量中的至少一种，以及光线强度值，确定充电模式。在一些情况下，可以先判断光线强度值是否满足一定的条件，再基于光线强度值的判断结果结合其他因素确定充电模式。
可选地，在一些实施例中，根据所述持续时长、所述当前时刻以及所述当前剩余电量中的至少一种，以及所述光线强度值，确定所述充电模式，包括：判断所述光线强度值是否小于或等于第一阈值；在所述光线强度值小于或等于所述第一阈值的情况下，根据所述持续时长、所述当前时刻以及所述当前剩余电量中的至少一种，确定所述充电模式。
本申请实施例中，以第一阈值为0.3为例进行说明，若电子设备所处环境的光线强度值为0.2，该值小于第一阈值0.3，再根据持续时长、当前时刻以及当前剩余电量中的至少一种，确定充电模式。
换句话说，在光线强度值小于或等于第一阈值的情况下，才根据持续时长、当前时刻以及当前剩余电量中的至少一种，确定充电模式；若光线强度值大于第一阈值，可以直接利用第二充电模式对电子设备进行充电。
应理解，在一些情况下，若光线强度值大于第一阈值，也可以再根据持续时长、当前时刻以及当前剩余电量中的至少一种，确定充电模式。例如，在夜间，由于灯光的照射误判电子设备所处环境的光线强度值大于第一阈值，此时，可以再根据持续时长、当前时刻以及当前剩余电量中的至少一种，确定充电模式。
可选地，在一些实施例中，所述根据所述持续时长、所述当前时刻以及所述当前剩余电量中的至少一种，确定所述充电模式，包括：在满足第一条件的情况下，确定第一充电模式为所述充电模式，否则确定第二充电模式为所述充电模式，所述第二充电模式的充电电流大于所述第一充电模式的充电电流；所述第一条件包括以下条件中的至少一种：所述持续时长大于或等于第二阈值、所述当前时刻属于第一时间段和所述当前剩余电量小于或等于第三阈值。

若电子设备在光照强度为0.2Lux下所持续的时长为2min，满足电子设备所处环境的光线强度值小于第一阈值，而在光照强度为0.2Lux下所持续的时长小于第二阈值，则可以利用第二充电模式对电子设备进行充电，即利用快速充电模式对电子设备进行充电。
本申请实施例中，例如，若第一阈值为0.3Lux，第一时间段为00:00-06:00，若电子设备所处环境的光照强度为0.2Lux，若当前时刻为1:00，同时满足电子设备所处环境的光线强度值小于第一阈值且当前时刻属于第一时间段，则可以利用第一充电模式对电子设备进行充电，即利用低于快速充电的充电模式对电子设备进行充电；否则利用第二充电模式对电子设备进行充电，即利用快速充电模式对电子设备进行充电。
若电子设备所处环境的光照强度为0.2Lux且当前时刻为20:00，满足电子设备所处环境的光线强度值小于第一阈值，而当前时刻不属于第一时间段，则可以利用第二充电模式对电子设备进行充电，即利用快速充电模式对电子设备进行充电。
本申请实施例中的第一时间段也可以为1:00-7:00，或者为1:00-6:00，本申请对此不作具体限定。
本申请实施例中，例如，若第一阈值为0.3Lux，第三阈值为10％，若电子设备所处环境的光照强度为0.2Lux，若电子设备当前剩余电量为5％，同时满足电子设备所处环境的光线强度值小于第一阈值且当前剩余电量小于第三阈值，则可以利用第一充电模式对电子设备进行充电，即利用低于快速充电的充电模式对电子设备进行充电；否则利用第二充电模式对电子设备进行充电，即利用快速充电模式对电子设备进行充电。
若电子设备所处环境的光照强度为0.2Lux且当前剩余电量为20％，满足电子设备所处环境的 光线强度值小于第一阈值，而当前剩余电量大于第三阈值，则可以利用第二充电模式对电子设备进行充电，即利用快速充电模式对电子设备进行充电。
应理解，若电子设备在光照强度为0.2Lux下所持续的时长大于5min且当前时刻为1:00，同时满足电子设备所处环境的光线强度值小于第一阈值且在光照强度为0.2Lux下所持续的时长大于第二阈值且当前时刻属于第一时间段的范围内，则可以利用第一充电模式对电子设备进行充电，即利用低于快速充电的充电模式对电子设备进行充电；否则利用第二充电模式对电子设备进行充电，即利用快速充电模式对电子设备进行充电，换句话说，电子设备在光照强度为0.2Lux下所持续的时长小于5min且当前时刻不属于第一时间段的范围内，利用第二充电模式对电子设备进行充电。
类似地，若第一条件为电子设备在光照强度为0.2Lux下所持续的时长大于5min且当前剩余电量小于或等于10％，则可以利用第一充电模式对电子设备进行充电；否则利用第二充电模式对电子设备进行充电，换句话说，电子设备在光照强度为0.2Lux下所持续的时长小于5min且当前剩余电量大于10％，利用第二充电模式对电子设备进行充电。
应理解，本申请实施例中的数值仅为举例说明，还可以为其他数值，不应对本申请造成特别限定。

本申请实施例中，在确定充电模式为第一充电模式的情况下，可以根据其他一些因素来尽量准确控制充电时间。例如，若电池的容量值为3000mAh，当前剩余电量值为0，当前时刻为1:00，预设时刻为6:00，即需要在5h内将电池充满，则可以利用0.6A的电流对电池进行充电。在这种情况下，若用户6:00起床，刚好在6:00将电子设备充满。
若前剩余电量值为5％，当前时刻为1:00，预设时刻为6:00，即需要在5h内将电池充满，则可以利用0.57A的电流对电子设备进行充电。在这种情况下，也可以使得电子设备在6:00刚好被充满。
应理解，若充电模式为第二充电模式，也可以基于类似的方法确定充电电流，使得用户刚好在预设时刻将电子设备充满。具体的设置方法可以参见第一充电模式的情况，为了简洁，这里不再赘述。

下面结合图6-图7，对本申请实施例应用的有线充电过程进行描述。
图6是本申请实施例提供的一种充电系统的示意性结构图。该充电系统包括电源提供装置10、 电池管理电路20和电池30。电池管理电路20可用于对电池30进行管理。其中，本申请实施例中的充电设备300和电子设备500可以包括电池管理电路20和电池30。
作为一个示例，电池管理电路20可以对电池30的充电过程进行管理，比如选择充电通道、控制充电电压和/或充电电流等；作为另一个示例，电池管理电路20可以对电池30的电芯进行管理，如均衡电池30中的电芯的电压等。
电池管理电路20可以包括第一充电通道21和通信控制电路23。
第一充电通道21可用于接收电源提供装置10提供的充电电压和/或充电电流，并将充电电压和/或充电电流加载在电池30的两端，为电池30进行充电。
第一充电通道21例如可以是一根导线，也可以在第一充电通道21上设置一些与充电电压和/或充电电流变换无关的其他电路器件。例如，电源管理电路20包括第一充电通道21和第二充电通道，第一充电通道21上可以设置用于充电通道间切换的开关器件(具体参见图7的描述)。
电源提供装置10可以是上文描述的输出电压可调的电源提供装置，但本申请实施例对电源提供装置20的类型不做具体限定。例如，该电源提供装置20可以是适配器和移动电源(power bank)等专门用于充电的设备，也可以是电脑等能够提供电源和数据服务的其他设备。
第一充电通道21可以为直充通道，可以将电源适配器10提供的充电电压和/或充电电流直接加载在电池30的两端。为了实现直充充电方式，本申请实施例在电池管理电路20中引入了具有通信功能的控制电路，即通信控制电路23。该通信控制电路23可以在直充过程中与电源提供装置10保持通信，以形成闭环反馈机制，使得电源提供装置10能够实时获知电池的状态，从而不断调整向第一充电通道注入的充电电压和/或充电电流，以保证电源提供装置10提供的充电电压和/或充电电流的大小与电池30当前所处的充电阶段相匹配。
例如，该通信控制电路23可以在电池30的电压达到恒流阶段对应的充电截止电压时，与电源提供装置10进行通信，使得电源提供装置10对电池30的充电过程从恒流充电转换为恒压充电。又例如，该通信控制电路23可以在电池30的充电电流达到恒压阶段对应的充电截止电流时，与电源提供装置10进行通信，使得电源提供装置10对电池30的充电过程从恒压充电转换为恒流充电。
本申请实施例提供的电池管理电路能够对电池进行直充，换句话说，本申请实施例提供的电池管理电路是支持直充架构的电池管理电路，在直充架构中，直充通道上无需设置变换电路，从而能够降低待充电设备在充电过程的发热量。
可选地，在一些实施例中，如图7所示，电池管理电路20还可包括第二充电通道24。第二充电通道24上设置有升压电路25。在电源提供装置10通过第二充电通道24为电池30充电的过程中，升压电路25可用于接收电源提供装置10提供的初始电压，将初始电压升压至目标电压，并基于目标电压为电池30充电，其中初始电压小于电池30的总电压，目标电压大于电池30的总电压；通信控制电路23还可用于控制第一充电通道21和第二充电通道24之间的切换。
假设该电池30包括多节电芯，该第二充电通道24能够兼容普通的电源提供装置为该电池30进行充电，解决了普通电源提供装置无法为多节电池进行充电的问题。
对于包含多节电芯的电池30来说，电池管理电路20还可以包括均衡电路22，参见上文的描述，该均衡电路22可用于在电池的充电过程和/或放电过程中均衡多节电芯的电压。
本申请实施例对升压电路25的具体形式不作限定。例如，可以采用Boost升压电路，还可以采用电荷泵进行升压。可选地，在一些实施例中，第二充电通道24可以采用传统的充电通道设计方式，即在第二充电通道24上设置变换电路(如充电IC)。该变换电路可以对电池30的充电过程进行恒压、恒流控制，并根据实际需要对电源提供装置10提供的初始电压进行调整，如升压或降压。本申请实施例可以利用该变换电路的升压功能，将电源提供装置10提供的初始电压升压至目标电压。
通信控制电路23可以通过开关器件实现第一充电通道21和第二充电通道24之间的切换。具体地，如图7所示，第一充电通道21上可以设置有开关管Q5，当通信控制电路23控制开关管Q5导通时，第一充电通道21工作，对电池30进行直充；当通信控制电路23控制开关管Q5关断时，第二充电通道24工作，采用第二充电通道24对电池30进行充电。
在另外一些实施例中，也可在第二充电通道24上设置用于降压的电路或器件，当电源提供装置提供的电压高于电池30的需求电压时，可进行降压处理。本申请实施例，对第二充电通道24包 含的电路或模块不进行限制。
下面结合图8-图11，对本申请实施例应用的无线充电过程进行描述。
传统的无线充电技术一般将电源提供装置(如适配器)与无线充电装置(如无线充电底座)相连，并通过该无线充电装置将电源提供装置的输出功率以无线的方式(如电磁波)传输至待充电设备，对待充电设备进行无线充电。该待充电设备可以为上文中的电子设备。
按照无线充电原理不同，无线充电方式主要分为磁耦合(或电磁感应)、磁共振以及无线电波三种方式。目前，主流的无线充电标准包括QI标准、电源实物联盟(power matters alliance，PMA)标准、无线电源联盟(alliance for wireless power，A4WP)。QI标准和PMA标准均采用磁耦合方式进行无线充电。A4WP标准采用磁共振方式进行无线充电。
下面结合图8，对一实施例的无线充电方式进行介绍。
如图8所示，无线充电系统包括电源提供装置110、无线充电信号的发射装置120以及充电控制装置130，其中发射装置120例如可以是无线充电底座，充电控制装置130可以指本申请实施例中的充电设备300或电子设备500。
电源提供装置110与发射装置120连接之后，会将电源提供装置110的输出电压和输出电流传输至发射装置120。
发射装置120可以通过内部的无线发射电路121将电源提供装置110的输出电压和输出电流转换成无线充电信号(例如，电磁信号)进行发射。例如，该无线发射电路121可以将电源提供装置110的输出电流转换成交流电，并通过发射线圈或发射天线将该交流电转换成无线充电信号。
图8只是示例性地给出了无线充电系统的示意性结构图，但本申请实施例并不限于此。例如，发射装置120也可以称为无线充电信号的发射装置，充电控制装置130也可以称为无线充电信号的接收装置。无线充电信号的接收装置例如可以是具有无线充电信号接收功能的芯片，可以接收发射装置120发射的无线充电信号；该无线充电信号的接收装置也可以是待充电设备。
充电控制装置130可以通过无线接收电路131接收无线发射电路121发射的无线充电信号，并将该无线充电信号转换成无线接收电路131的输出电压和输出电流。例如，该无线接收电路131可以通过接收线圈或接收天线将无线发射电路121发射的无线充电信号转换成交流电，并对该交流电进行整流和/或滤波等操作，将该交流电转换成无线接收电路131的输出电压和输出电流。
在一些实施例中，在无线充电之前，发射装置120与充电控制装置130会预先协商无线发射电路121的发射功率。假设发射装置120与充电控制装置130之间协商的功率为5W，则无线接收电路131的输出电压和输出电流一般为5V和1A。假设发射装置120可与充电控制装置130之间协商的功率为10.8W，则无线接收电路131的输出电压和输出电流一般为9V和1.2A。
若无线接收电路131的输出电压并不适合直接加载到电池133两端，则是需要先经过充电控制装置130内的变换电路132进行恒压和/或恒流控制，以得到充电控制装置130内的电池133所预期的充电电压和/或充电电流。
变换电路132可用于对无线接收电路131的输出电压进行变换，以使得变换电路132的输出电压和/或输出电流满足电池133所预期的充电电压和/或充电电流的需求。
作为一种示例，该变换电路132例如可以是充电集成电路(integrated circuit，IC)，或者可以为电源管理电路。在电池133的充电过程中，变换电路132可用于对电池133的充电电压和/或充电电流进行管理。该变换电路132可以包含电压反馈功能，和/或，电流反馈功能，以实现对电池133的充电电压和/或充电电流的管理。
在正常的充电过程中，电池所需的充电电压和/或充电电流在不同的充电阶段可能在不断发生变化。无线接收电路的输出电压和/或输出电流可能就需要不断地调整，以满足电池当前的充电需求。例如，在电池的恒流充电阶段，在充电过程中，电池的充电电流保持不变，但是电池的电压在不断升高，因此电池所需的充电电压也在不断升高。随着电池所需的充电电压的不断增大，电池所需的充电功率也在不断增大。当电池所需的充电功率增大时，无线接收电路需要增大输出功率，以满足电池的充电需求。
当无线接收电路的输出功率小于电池当前所需的充电功率时，通信控制电路可以向发射装置发射指示信息以指示发射装置提升发射功率，以增大无线接收电路的输出功率。因此，在充电过程中，通信控制电路可以与发射装置通信，使得无线接收电路的输出功率能够满足电池不同充电阶段的充 电需求。
本申请实施例对通信控制电路235与发射装置220的通信方式不做具体限定。可选地，在一些实施例中，通信控制电路235与发射装置220可以采用蓝牙(bluetooth)通信、无线保真(wireless fidelity，Wi-Fi)通信或反向散射(backscatter)调制方式(或功率负载调制方式)通信、基于高载波频率的近距离无线通信、光通信、超声波通信、超宽带通信或移动通信等无线通信方式进行通信。
在一实施例中，基于高载波频率的近距离无线通信模块可以包括内部封装有极高频(extremely high frequency，EHF)天线的集成电路(integrated circuit，IC)芯片。可选地，高载波频率可以为60GHz。
在一实施例中，光通信可以是利用光通信模块进行通信。光通信模块可以包括红外通信模块，红外通信模块可利用红外线传输信息。
在一实施例中，移动通信可以是利用移动通信模块进行通信。移动通信模块可利用5G通信协议、4G通信协议或3G通信协议等移动通信协议进行信息传输。
采用上述的无线通信方式，相比于Qi标准中通过信号调制的方式耦合到无线接收电路的线圈进行通信的方式，可提高通信的可靠性，且可避免采用信号耦合方式通信带来的电压纹波，影响降压电路的电压处理过程。
可选地，通信控制电路235与发射装置220也可以采用数据接口的有线通信方式进行通信。
图9是本申请实施例提供的充电系统的另一示意图。请参见图9，无线充电信号的发射装置220还可以包括充电接口223，充电接口223可用于与外部的电源提供装置210相连。无线发射电路221还可用于根据电源提供装置210的输出电压和输出电流，生成无线充电信号。
第一通信控制电路222还可以在无线充电的过程中，调整无线发射电路221从电源提供装置210的输出功率中抽取的功率量，以调整无线发射电路221的发射功率，使得无线发射电路发射的功率能够满足电池的充电需求。例如，电源提供装置210也可以直接输出较大的固定功率(如40W)，第一通信控制电路222可以直接调整无线发射电路221从电源提供装置210提供的固定功率中抽取的功率量。
本申请实施例中，电源提供装置210的输出功率可以是固定的。例如，电源提供装置210可以直接输出较大的固定功率(如40W)，电源提供装置210可以按照该固定的输出功率向无线充电装置220提供输出电压和输出电流。在充电过程中，第一通信控制电路222可以根据实际需要从该电源提供装置的固定功率中抽取一定的功率量用于无线充电。也就是说，本申请实施例将无线发射电路221的发射功率调整的控制权分配给第一通信控制电路222，第一通信控制电路222能够在接收到第二通信控制电路235发送的指示信息之后立刻对无线发射电路221的发射功率进行调整，以满足电池当前的充电需求，具有调节速度快、效率高的优点。
本申请实施例对第一通信控制电路222从电源提供装置210提供的最大输出功率中抽取功率量的方式不做具体限定。例如，可以在无线充电信号的发射装置220内部设置电压转换电路224，该电压转换电路224可以与发射线圈或发射天线相连，用于调整发射线圈或发射天线接收到的功率。该电压转换电路224例如可以包括脉冲宽度调制(pulse width modulation，PWM)控制器和开关单元。第一通信控制电路222可以通过调整PWM控制器发出的控制信号的占空比调整无线发射电路221的发射功率。
本申请实施例对电源提供装置210的类型不做具体限定。例如，电源提供装置210可以为适配器、移动电源(power bank)、车载充电器或电脑等设备。
本申请实施例对充电接口223的类型不做具体限定。可选地，在一些实施例中，该充电接口223可以为USB接口。该USB接口例如可以是USB 2.0接口，micro USB接口，或USB TYPE-C接口。可选地，在另一些实施例中，该充电接口223还可以是lightning接口，或者其他任意类型的能够用于充电的并口和/或串口。
本申请实施例对第一通信控制电路222与电源提供装置210之间的通信方式不做具体限定。作为一个示例，第一通信控制电路222可以通过除充电接口之外的其他通信接口与电源提供装置210相连，并通过该通信接口与电源提供装置210通信。作为另一个示例，第一通信控制电路222可以以无线的方式与电源提供装置210进行通信。例如，第一通信控制电路222可以与电源提供装置210进行近场通信(Near Field Communication，NFC)。作为又一个示例，第一通信控制电路222可以 通过充电接口223与电源提供装置210进行通信，而无需设置额外的通信接口或其他无线通信模块，这样可以简化无线充电装置220的实现。例如，充电接口223为USB接口，第一通信控制电路222可以与电源提供装置210基于该USB接口中的数据线(如D+和/或D-线)进行通信。又如，充电接口223可以为支持功率传输(Power Delivery，PD)通信协议的USB接口(如USB TYPE-C接口)，第一通信控制电路222与电源提供装置210可以基于PD通信协议进行通信。
可选地，第一通信控制电路222调整无线充电信号的发射功率可以指，第一通信控制电路222通过调整无线发射电路221的输入电压和/或输入电流来调整无线充电信号的发射功率。例如，第一通信控制电路可以通过增大无线发射电路的输入电压来增大无线发射电路的发射功率。
可选地，如图11所示，待充电设备230还包括第一充电通道233，通过该第一充电通道233可将无线接收电路231的输出电压和/或输出电流提供给电池232，对电池232进行充电。

可选地，增大无线发射电路221的发射功率可以指增大无线发射电路221的发射电压，增大无线发射电路221的发射电压可以通过增大电压转换电路224的输出电压来实现。例如，第一通信控制电路222接收到第二通信控制电路235发送的指示增大发射功率的指示信息后，可以通过增大电压转换电路224的输出电压来增大无线发射电路221的发射功率。
本申请实施例对第二通信控制电路235向第一通信控制电路222发送指示信息的方式不做具体限定。
例如，第二通信控制电路235可以定期向第一通信控制电路222发送指示信息。或者，第二通信控制电路235可以仅在电池的电压达到充电截止电压，或者电池的充电电流达到充电截止电流的情况下，再向第一通信控制电路222发送指示信息。
可选地，无线充电信号的接收装置还可包括检测电路234，该检测电路234可以检测电池232的电压和/或充电电流，第二通信控制电路235可以根据电池232的电压和/或充电电流，向第一通信控制电路222发送指示信息，以指示第一通信控制电路222调整无线发射电路221的发射功率对应的输出电压和输出电流。
在一实施例中，对待充电设备而言，在恒流充电的过程中，电池的电压会不断上升，电池所需的充电功率也会随之增大。此时，需要增大无线充电信号的发射功率，以满足电池当前的充电需求。在恒压充电的过程中，电池的充电电流可能会不断减小，电池所需的充电功率也会随之减小。此时，需要减小无线充电信号的发射功率，以满足电池当前的充电需求。
第一通信控制电路222可以根据指示信息调整无线充电信号的发射功率，可以指第一通信控制电路222调整无线充电信号的发射功率，使得无线充电信号的发射功率与电池的当前所需的充电电压和/或充电电流相匹配。
无线发射电路221的发射功率与电池232当前所需的充电电压和/或充电电流相匹配可以指：第一通信控制电路222对无线充电信号的发射功率的配置使得第一充电通道233的输出电压和/或输出电流与电池232当前所需的充电电压和/或充电电流相匹配(或者，第一通信控制电路222对无线充电信号的发射功率的配置使得第一充电通道233的输出电压和/或输出电流满足电池232的充电需求(包括电池232对充电电压和/或充电电流的需求))。
应理解，在本公开的一实施例中，“第一充电通道232的输出电压和/或输出电流与电池232当前所需的充电电压和/或充电电流相匹配”包括：第一充电通道232输出的直流电的电压值和/或电流值与电池232所需的充电电压值和/或充电电流值相等或在浮动预设范围(例如，电压值上下浮动100毫伏～200毫伏，电流值上下浮动0.001A～0.005A等)。
上述第二通信控制电路235根据检测电路234检测到的电池232的电压和/或充电电流，与第一通信控制电路222进行无线通信，以便第一通信控制电路222根据电池232的电压和/或充电电流，调整无线发射电路221的发射功率可以包括：在电池232的恒流充电阶段，第二通信控制电路235根据检测到的电池的电压，与第一通信控制电路222进行无线通信，以便第一通信控制电路222调整无线发射电路221的发射功率，使得第一充电通道233的输出电压与该恒流充电阶段电池所需的 充电电压相匹配(或者，使得第一充电通道233的输出电压满足电池232在恒流充电阶段对充电电压的需求)。
图10是本申请实施例提供的充电系统的的另一示例。图10的实施例对应的无线充电信号的发射装置220并非从电源提供装置210获取电能，而是直接将外部输入的交流电(如市电)转换成上述无线充电信号。
如图10所示，无线充电信号的发射装置220还可包括电压转换电路224和电源提供电路225。电源提供电路225可用于接收外部输入的交流电(如市电)，并根据交流电生成电源提供电路225的输出电压和输出电流。例如，电源提供电路225可以对交流电进行整流和/或滤波，得到直流电或脉动直流电，并将该直流电或脉动直流电传输至电压转换电路224。
电压转换电路224可用于接收电源提供电路225的输出电压，并对电源提供电路225的输出电压进行转换，得到电压转换电路224的输出电压和输出电流。无线发射电路221还可用于根据电压转换电路224的输出电压和输出电流，生成无线充电信号。
本申请实施例在无线充电信号的发射装置220内部集成了类似适配器的功能，使得该无线充电信号的发射装置220无需从外部的电源提供装置获取功率，提高了无线充电信号的发射装置220的集成度，并减少了实现无线充电过程所需的器件的数量。
可选地，在一些实施例中，无线充电信号的发射装置220可以支持第一无线充电模式和第二无线充电模式，无线充电信号的发射装置220在第一无线充电模式下对待充电设备的充电速度快于无线充电信号的发射装置220在第二无线充电模式下对待充电设备的充电速度。换句话说，相较于工作在第二无线充电模式下的无线充电信号的发射装置220来说，工作在第一无线充电模式下的无线充电信号的发射装置220充满相同容量的待充电设备中的电池的耗时更短。
本申请实施例提供的充电方法可以使采用第一充电模式进行充电，也可以使采用第二充电模式进行充电，本申请实施例对此不做限定。
第二无线充电模式可为称为普通无线充电模式，例如可以是传统的基于QI标准、PMA标准或A4WP标准的无线充电模式。第一无线充电模式可为快速无线充电模式。该普通无线充电模式可以指无线充电信号的发射装置220的发射功率较小(通常小于15W，常用的发射功率为5W或10W)的无线充电模式，在普通无线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；而在快速无线充电模式下，无线充电信号的发射装置220的发射功率相对较大(通常大于或等于15W)。相较于普通无线充电模式而言，无线充电信号的发射装置220在快速无线充电模式下完全充满相同容量电池所需要的充电时间能够明显缩短、充电速度更快。
参见图11，在本公开的一实施例中，待充电设备230还包括：第二充电通道236。第二充电通道236可为导线。在第二充电通道236上可设置变换电路237，用于对无线接收电路231输出的直流电进行电压控制，得到第二充电通道236的输出电压和输出电流，以对电池232进行充电。
在一个实施例中，变换电路237可用于降压电路，并且输出恒流和/或恒压的电能。换句话说，该变换电路237可用于对电池的充电过程进行恒压和/或恒流控制。
当采用第二充电通道236对电池232进行充电时，无线发射电路221可采用恒定发射功率发射电磁信号，无线接收电路231接收电磁信号后，由变换电路237处理为满足电池232充电需求的电压和电流并输入电池232，实现对电池232的充电。应理解，在一些实施例中，恒定发射功率不一定是发射功率完全保持不变，其可在一定的范围内变动，例如，发射功率为7.5W上下浮动0.5W。
在本公开的实施例中，通过第一充电通道233对电池232进行充电的充电方式为第一无线充电模式，通过第二充电通道236对电池232进行充电的方式称为第二无线充电模式。无线充电信号的发射装置和待充电设备可通过握手通信确定采用第一无线充电模式还是第二无线充电模式对电池232进行充电。
本公开实施例中，对于无线充电信号的发射装置，当通过第一无线充电模式对待充电设备充电时，无线发射电路221的最大发射功率可为第一发射功率值。而通过第二无线充电模式对待充电设备进行充电时，无线发射电路221的最大发射功率可为第二发射功率值。其中，第一发射功率值大于第二发射功率值，由此，采用第一无线充电模式对待充电设备的充电速度大于第二无线充电模式。
可选地，第二通信控制电路235还可用于控制第一充电通道233和第二充电通道236之间的切 换。例如，如图11所示，第一充电通道233上可以设置开关238，第二通信控制电路235可以通过控制该开关238的导通与关断控制第一充电通道233和第二充电通道236之间的切换。上文指出，在某些实施例中，无线充电信号的发射装置220可以包括第一无线充电模式和第二无线充电模式，且无线充电信号的发射装置220在第一无线充电模式下对待充电设备230的充电速度快于无线充电信号的发射装置220在第二无线充电模式下对待充电设备230的充电速度。当无线充电信号的发射装置220使用第一无线充电模式为待充电设备230内的电池充电时，待充电设备230可以控制第一充电通道233工作；当无线充电信号的发射装置220使用第二无线充电模式为待充电设备230内的电池充电时，待充电设备230可以控制第二充电通道236工作。
在待充电设备侧，第二通信控制电路235可以根据充电模式，在第一充电通道233和第二充电通道236之间进行切换。当采用第一无线充电模式时，第二通信控制电路235控制第一充电通道233上的电压转换电路239工作。当采用第二无线充电模式时，第二通信控制电路235控制第二充电通道236上的变换电路237工作。
可选地，无线充电信号的发射装置220可以与待充电设备230之间进行通信，以协商无线充电信号的发射装置220与待充电设备230之间的充电模式。
除了上文描述的通信内容外，无线充电信号的发射装置220中的第一通信控制电路222与待充电设备230中的第二通信控制电路235之间还可以交互许多其他通信信息。在一些实施例中，第一通信控制电路222和第二通信控制电路235之间可以交互用于安全保护、异常检测或故障处理的信息，如电池232的温度信息，进入过压保护或过流保护的指示信息等信息，功率传输效率信息(该功率传输效率信息可用于指示无线发射电路221和无线接收电路231之间的功率传输效率)。
可选地，第二通信控制电路235与第一通信控制电路222之间的通信可以为单向通信，也可以为双向通信，本申请实施例对此不做具体限定。
在本申请的实施例中，第二通信控制电路的功能可由待充电设备230的应用处理器实现，由此，可以节省硬件成本。或者，也可由独立的控制芯片实现，由独立的控制芯片实现可提高控制的可靠性。
可选地，本申请实施例可以将无线接收电路232与电压转换电路239均集成在同一无线充电芯片中，这样可以提高待充电设备集成度，简化待充电设备的实现。例如，可以对传统无线充电芯片的功能进行扩展，使其支持充电管理功能。

当用于本申请中时，虽然术语“第一”、“第二”等可能会在本申请中使用以描述各设备，但这些设备不应受到这些术语的限制。这些术语仅用于将一个设备与另一个设备区别开。比如，在不改变描述的含义的情况下，第一设备可以叫做第二设备，并且同样地，第二设备可以叫做第一设备，只要所有出现的“第一设备”一致重命名并且所有出现的“第二设备”一致重命名即可。第一设备和第二设备都是设备，但可以不是相同的设备。

另外，在本申请各个实施例中的各功能单元可以集成在一个处理单元中，也可以是各个单元单独物理存在，也可以两个或两个以上单元集成在一个单元中。
以上所述，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以所述权利要求的保护范围为准。
