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清楚、完整地描述。
本申请实施例是基于无线充电技术对待充电设备进行充电，无线充电技术不需要电缆即可完成功率的传输，能够简化充电准备阶段的操作。
传统的无线充电技术一般将电源提供设备(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设备的输出功率以无线的方式(如电磁信号或 电磁波)传输至待充电设备，对待充电设备进行无线充电。
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。
下面将结合图1，对传统的无线充电方式进行介绍。
如图1所示，无线充电系统包括电源提供设备110、无线充电装置120以及待充电设备130，其中电源提供设备110例如可以是适配器，无线充电装置120例如可以是无线充电底座，待充电设备130例如可以是终端。
电源提供设备110与无线充电装置120连接之后，会将电源提供设备110的输出电流传输至无线充电装置120。无线充电装置120可以通过内部的无线发射电路121将电源提供设备110的输出电流转换成电磁信号(或电磁波)进行发射。例如，该无线发射电路121可以将电源提供设备110的输出电流转换成交流电，并通过发射线圈或发射天线(图中未示出)将该交流电转换成电磁信号。
待充电设备130可以通过内部的无线接收电路131接收无线发射电路121发射的电磁信号，并将该电磁信号转换成无线接收电路131的输出电流。例如，该无线接收电路131可以通过接收线圈或接收天线(图中未示出)将无线发射电路121发射的电磁信号转换成交流电，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。
对于传统无线充电技术，在无线充电之前，无线充电装置121与待充电设备130会预先协商无线发射电路121的发射功率。假设无线充电装置120与待充电设备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。假设无线充电装置120与待充电设备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。
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，而是需要先经过待充电设备130内的变换电路132进行变换，以得到待充电设备
130内的电池133所预期的充电电压和/或充电电流。具体地，待充电设备130内部的第一充电通道134可将无线接收电路131的输出电压和输出电流输入到变换电路132内，并将经过变换电路132变换后的输出电压和输出电流通过第一充电通道134加载在电池133的两端，以满足电池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可指充电管理模块，例如充电集成电路(integrated circuit，IC)。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。
举例来说，电池的充电过程可包括涓流充电阶段，恒流充电阶段和恒压充电阶段中的一个或者多个。在涓流充电阶段，变换电路132可利用电流反馈功能使得在涓流充电阶段进入到电池133的电流满足电池133所预期的充电电流大小(譬如第一充电电流)。在恒流充电阶段，变换电路132可利用电流反馈功能使得在恒流充电阶段进入电池133的电流满足电池133所预期的充电电流大小(譬如第二充电电流，该第二充电电流可大于第一充电电流)。在恒压充电阶段，变换电路132可利用电压反馈功能使得在恒压充电阶段加载到电池133两端的电压的大小满足电池133所预期的充电电压大小。
作为一种示例，当无线接收电路131的输出电压大于电池133所预期的充电电压时，变换电路132可用于对无线接收电路131的输出电压进行降压处理，以使降压转换后得到的充电电压满足电池133所预期的充电电压需求。作为又一种示例，当无线接收电路131的输出电压小于电池133所预期的充电电压时，变换电路132可用于对无线接收电路131的输出电压进行升压处理，以使升压转换后得到的充电电压满足电池133所预期的充电电压需求。
作为又一示例，以无线接收电路131输出5V恒定电压为例，当电池133包括单个电芯(以锂电池电芯为例，单个电芯的充电截止电压一般为4.2V)时，变换电路132(例如Buck降压电路)可对无线接收电路131的输出电压进行降压处理，以使得降压后得到的充电电压满足电池133所预期的充电电压需求。
作为又一示例，以无线接收电路131输出5V恒定电压为例，当电池133包括相互串联的两节或两节以上电芯(以锂电池电芯为例，单个电芯的充电截止电压一般为4.2V)时，变换电路132(例如Boost升压电路)可对无线接收电路131的输出电压进行升压处理，以使得升压后得到的充电电压满足电池133所预期的充电电压需求。
变换电路132受限于电路转换效率低下的原因，致使未被转换部分的电能以热量的形式散失。待充电设备130的设计空间和散热空间都很小(例如，用户使用的移动终端物理尺寸越来越轻薄，同时移动终端内密集排布了大量的电子元器件以提升移动终端的性能)，这不但提升了变换电路132的设计难度，还会导致聚焦在待充电设备130内的热量很难及时移除，进而引发待充电设备130的异常。
例如，变换电路132上聚集的热量可能会对变换电路132附近的电子元器件造成热干扰，引发电子元器件的工作异常。又如，变换电路132上聚集的热量，可能会缩短变换电路132及附近电子元件的使用寿命。又如，变换电路132上聚集的热量，可能会对电池133造成热干扰，进而导致电池133充放电异常。又如变换电路132上聚集的热量，可能会导致待充电设备130的温度升高，影响用户在充电时的使用体验。又如，变换电路132上聚集的热量，可能会导致变换电路132自身的短路，使得无线接收电路131的输出电压直接加载在电池133两端而引起充电异常，如果电池133长时间处于过压充电状态，甚至会引发电池133的爆炸，危及用户安全。
为了解决上述问题，本申请实施例提供的无线充电系统可以不同于传统的无线充电系统，该无线充电系统中的无线充电装置可以与待充电设备之间进行无线通信。且该无线充电装置的发射功率可以基于待充电设备的反馈信息进行调节，使得无线充电装置的发射功率与待充电设备内部的电池当前所需的充电电压和/或充电电流相匹配(或与待充电设备内部的电池当前所处的充电阶段相匹配)。无线充电装置的发射功率与电池当前所需的充电电压和/或充电电流相匹配可以指：无线充电装置对电磁信号的发射功率的配置使得该电磁信号被无线接收电路接收之后，无线接收电路的输出电压和/或输出电流与待充电设备内部的电池所需的充电电压和/或充电电流相匹配(或无线接收电路的输出电压和/或输出电流满足待充电设备内部的电池的充电需求)。这样一来，在待充电设备中，无线接收电路的输出电压和/或输出电流就可以直接加载在电池的两端，为电池进行充电(下文将待充电设备的这种充电方式成为直充)，从而可以避免上文描述的变换电路对无线接收电路的输出电压和/或输出电流进行变换而引发的能量损失、发热等问题。
下面先结合图2，对直充的无线充电方式进行介绍。
如图2所示，无线充电系统包括电源提供设备210，无线充电装置220以及待充电设备230。其中电源提供设备210例如可以是适配器，无线充电装置220例如可以是无线充电底座，待充电设备230例如可以是终端。
无线充电装置220可以包括：无线发射电路221和第一通信控制电路222。第一通信控制电路222中的控制功能例如可以通过微控制单元(micro control unit，MCU)实现。
电源提供设备210与无线充电装置220连接之后，会将电源提供设备210的输出电流传输至无线充电装置220。无线充电装置220可以通过内部的无线发射电路221将电源提供设备210的输出电流转换成电磁信号(或电磁波)进行发射。例如，该无线发射电路221可以将电源提供设备210的输出电流转换成交流电，并通过发射线圈或发射天线(图中未示出)将该交流电转换成电磁信号。
第一通信控制电路222可用于在无线充电的过程中与待充电设备230进行无线通信。具体地，第一通信控制电路222可以与待充电设备230中的第二通信控制电路235进行通信。本发明实施例对第一通信控制电路222和第二通信控制电路235之间的通信 方式，以及第一通信控制电路222和第二通信控制电路235交互的通信信息不做具体限定，下文会结合具体的实施例进行详细描述。
待充电设备230可以包括：无线接收电路231、电池2352、第二充电通道233、检测电路234以及第二通信控制电路235。第二通信控制电路235中的控制功能例如可以通过微控制单元(micro control unit，MCU)实现，或者可以通过MCU与待充电设备内部的应用处理器(application processor，AP)共同实现。
待充电设备230可以通过内部的无线接收电路231接收无线发射电路221发射的电磁信号，并将该电磁信号转换成无线接收电路231的输出电流。例如，该无线接收电路231可以通过接收线圈或接收天线(图中未示出)将无线发射电路221发射的电磁信号转换成交流电，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231的输出电压和输出电流。检测电路234可用于检测无线接收电路231的输出电压和/或输出电流。需要说明的是，本发明实施例对整形电路的具体形式以及整形电路整形之后得到的无线接收电路231的输出电压和输出电流的形式不做具体限定。在一些实施例中，整形电路可以包括整流电路和滤波电路，无线接收电路231的输出电压可以为滤波之后得到的稳定的电压。在另一些实施例中，整形电路可以包括整流电路，无线接收电路231的输出电压可以为整流之后得到的脉动波形的电压，该脉动波形的电压直接加载到待充电设备230的电池232两端以对电池232进行充电。可以理解是，无线接收电路231的输出电流可以以间歇的方式为电池232充电，该无线接收电路231的输出电流的周期可以跟随输入无线充电系统200的交流电例如交流电网的频率进行变化，例如，无线接收电路231的输出电流的周期所对应的频率为电网频率的整数倍或倒数倍。并且，无线接收电路231的输出电流可以以间歇的方式为电池232充电时，无线接收电路231的输出电流对应的电流波形可以是与电网同步的一个或一组脉冲组成。脉动形式的电压/电流的大小周期性变换，与传统的恒定直流电相比，能够降低锂电池的析锂现象，提高电池的使用寿命，并且有利于降低电池的极化效应、提高充电速度、减少电池的发热，从而保证待充电设备充电时的安全可靠。
第二充电通道233可用于接收无线接收电路231的输出电压和输出电流，并基于无线接收电路231的输出电压和输出电流对电池232进行充电。第二充电通道233可基于无线接收电路231的输出电压和输出电流对电池232进行直充。例如，第二充电通道233可以是导线。又如，在待充电设备232包含多个充电通道的情况下，第二充电通道233上可以设置开关等器件，用于在不同充电通道之间进行切换。
检测电路234可用于检测无线接收电路231的输出电压和/或输出电流。在一些实施例中，检测电路234可以包括电压检测电路和电流检测电路。
电压检测电路可用于对无线接收电路231的输出电压进行采样，并将采样后的电压值传输至第二通信控制电路235。在一些实施例中，电压检测电路可以通过串联分压的方式对无线接收电路231的输出电压进行采样。
电流检测电路可用于对无线接收电路231的输出电流进行采样，并将采样后的电流值传输至第二通信控制电路235。在一些实施例中，电流检测电路可以通过检流电阻和检流计对无线接收电路231的输出电流进行采样。
第二通信控制电路235可用于根据检测电路234检测到的无线接收电路231的输出电压和/或输出电流，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调整无线发射电路221的发射功率，从而使得无线接收电路的输出电压和/或输出电流可以直接加载在电池232的两端。
目前，传统的无线充电技术仅限于标准无线充电方式，也就是说，无线充电装置可以采用如图1所示的无线充电模式对待充电设备进行充电，与无线充电装置相连的电源提供设备输出的是小于预设值且固定的最大输出功率(如QI标准中的5W)，待充电设备在这种无线充电模式下的充电时间过长。
因此，本申请实施例提供了一种无线充电方法。在该无线充电方法中无线充电装置 可以识别电源提供设备的类型，根据不同的电源提供设备的类型采用不同的无线充电模式对待充电设备进行充电。从而在电源提供设备的类型为快充类电源提供设备时能够对待充电设备进行快充，缩短充电时间。
下面将结合图3描述本申请实施例提供的无线充电方法300的示意性框图。如图3所示，该方法300可以由无线充电装置(如图2中的无线充电装置220)执行。该无线充电装置例如可以是无线充电底座，该方法300可以包括以下部分或全部内容：
S310，在无线充电装置与电源提供设备相连后，该无线充电装置识别该电源提供设备的类型。
S320，所述无线充电装置根据所述电源提供设备的类型，在目标无线充电模式下为待充电设备的电池进行充电，所述目标无线充电模式为第一无线充电模式或第二无线充电模式。
其中，所述无线充电装置在所述第一无线充电模式下对所述电池的充电速度大于所述无线充电装置在所述第二无线充电模式下对所述电池的充电速度。
需要说明的是，该电源提供设备的类型包括快充类和普通类，该快充类电源提供设备提供的最大输出功率大于或等于预设值，该普通类电源提供设备提供的最大输出功率小于该预设值。快充类电源提供设备可以指提供的最大输出功率大于或等于预设值的电源提供设备，而普通类电源提供设备可以指提供的最大输出功率小于预设值的电源提供设备。应理解，在本申请实施例中，“快充类”与“普通类”只是通过最大输出功率进行分类的，对电源提供设备的其他特性并不作区分。也就是说，该“快充类”与“普通类”可以等同于“第一类”与“第二类”。例如，可以将最大输出功率大于或等于20W的电源提供设备分类为快充类电源提供设备，而将最大输出功率小于20W的电源提供设备分类为普通电源提供设备。
无线充电装置在该第一无线充电模式下对该电池的充电速度大于该无线充电装置在该第二无线充电模式下对该电池的充电速度。就是说，相较于工作在第二无线充电模式下的无线充电装置来说，工作在第一无线充电模式下的无线充电装置充满相同容量的待充电设备中的电池的耗时更短。
第二无线充电模式可为称为普通无线充电模式。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装置的发射功率(或者输出功率)较小并且输出功率固定(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；而快速无线充电模式可以指无线充电装置的发射功率(或者输出功率)相对较大并且通常输出功率可调(通常大于或等于15W)的无线充电模式。相较于普通无线充电模式而言，无线充电装置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。
应理解，在一些实施例中，输出功率固定不一定是输出功率完全保持不变，其可在一定的范围内变动，例如，输出功率为10W上下浮动0.5W。
在本公开的一实施例中，如图4所示，无线充电装置220还可以包括：电压转换电路223。该电压转换电路223，用于在提供给无线发射电路221的电流的电压不满足预设条件时，对提供给无线发射电路221的电流进行电压变换。如前所述，在一个实施例中，提供给无线发射电路221的电流可为电源提供设备提供的。
当然，可替换地，如果提供给无线发射电路221的电压可以达到无线发射电路221对输入电压的电压需求，可以省去电压转换电路，以简化无线充电装置的实现。无线发射电路221对输入电压的电压需求可根据实际需求进行设置，例如，设置为10V。
在本公开的一实施例中，提供给无线发射电路221的电流的电压不能满足预设条件是指，该电压低于无线发射电路的需求电压，或，该电压高于无线发射电路221的需求电压。例如，无线充电装置220识别电源提供设备的类型为普通类，若该无线充电装置220采用前述第一无线充电模式对待充电设备进行无线充电，由于这种无线充电模式对无 线发射电路221的输入电压要求较高(如电压需求为10V或20V)，而普通类电源提供设备提供给无线发射电路221的电压无法达到无线发射电路221的电压需求，也就是无法达到待充电设备的电压需求，则电压转换电路223可以对输入电压进行升压处理，以使得升压后的电压达到无线发射电路221的电压需求；相反地，若无线充电装置220识别电源提供设备的类型为快充类，若该无线充电装置220采用前述第二无线充电模式对待充电设备进行无线充电，由于这种无线充电模式对无线发射电路221的输入电压要求比较低，而快充类电源提供设备提供给无线发射电路221的电压超过无线发射电路221的电压需求，电压转换电路223可以对输入电压进行降压处理，以使得降压后的电压达到无线发射电路221的电压需求。
因此，在电源提供设备为普通类电源提供设备时，通过电压转换电路，依然可实现采用第一无线充电模式对待充电设备进行充电；或者，在电源提供设备为快充类电源提供设备时，通过电压转换电路依然可实现采用第二无线充电模式对待充电设备进行充电，这样，既可以提高充电速度，也可以提高无线发射装置的兼容性。
在本申请的另一实施例中，该无线充电装置和待充电设备均可以支持第一无线充电模式和第二无线充电模式，并且该第一无线充电模式和第二无线充电模式可以对应待充电设备内的不同充电电路。具体地，可以结合图5进行描述。如图5所示，该待充电设备430包括无线接收电路431、电池432、第一充电通道433、变换电路434、第二充电通道435、检测电路436以及第二通信控制电路437。在第一无线充电模式下，待充电设备可以通过第二充电通道435将无线接收电路431的输出电压和输出电流直接加载到电池432的两端(同图2的工作原理)。
可选地，在一个实施例中，在该第二充电通道435上可设置降压电路。
降压电路，用于对无线接收电路431输出的直流电进行降压处理，得到第二充电通道435的输出电压和输出电流。在一个实施例中，该无线接收电路431输出的直流电的电压值和电流值，符合电池的充电需求，可以省去降压电路，将无线接收电路531直接加载到电池432以简化待充电设备的实现。在本公开的实施例中，降压电路的实现形式可以有多种。作为一个示例，降压电路可以为Buck电路。作为另一个示例，降压电路可以为电荷泵(charge pump)。电荷泵可以由多个开关器件构成，电流流过开关器件产生的热量很小，几乎与电流直接经过导线相当，所以采用电荷泵作为降压电路，不但可以起到降压效果，而且发热较低。作为另一个示例，降压电路还可为半压电路。
在一个实施例中，上述的无线充电装置220的电压转换电路的升压倍数和待充电设备430的降压电路的降压倍数的设置可以与电源提供设备能够提供的输出电压、电池需要的充电电压等参数有关，二者可以相等也可以不相等，本公开实施例对此不做具体限定。
作为一个示例，可以将电压转换电路的升压倍数与降压电路的降压倍数设置为相等。例如，电压转换电路可以是倍压电路，用于将电源提供设备的输出电压提升2倍；降压电路可以是半压电路，用于将无线接收电路的输出电压降低一半。因此，半压电路的输入电压和输出电压的压差固定，可减小半压电路的发热，提高转换效率。
在第二无线充电模式下，待充电设备可以通过第一充电通道433将无线接收电路431的输出电压和输出电流输入到变换电路434，并通过第一充电通道433将变换后的输出电压和输出电流加载到电池432两端(同图1的工作原理)。
本申请实施例中的无线充电装置可以与待充电设备之间进行无线通信。具体地，在电源提供设备与无线充电装置相连之后，该无线充电装置可以识别电源提供设备的类型，进而无线充电装置可以根据识别的电源提供设备的类型采用相应的无线充电模式对待充电设备进行充电。例如，若识别的电源提供设备为快充类电源提供设备，则无线充电装置可以使用第一无线充电模式对待充电设备进行充电；若识别的电源提供设备为普通类电源提供设备，则无线充电装置则可以使用第二无线充电模式对待充电设备进行充电。
可选地，在本申请实施例中，无线充电装置识别电源提供设备的类型可以是无线充 电装置在与电源提供设备相连之后，向电源提供设备发送请求询问指令，例如可以询问该电源提供设备是否为快充类电源提供设备，若无线充电装置接收到该请求询问指令的响应之后，则可以认为与之相连的电源提供设备为快充类电源提供设备，若无线充电装置未接收到该请求询问指令的响应，则可以认为相连的电源提供设备为普通类电源提供设备。应理解，本申请实施例对无线充电装置识别电源提供设备的类型的方式不作限定。
可选地，在一些实施例中，在第一无线充电模式下，该无线充电装置发射的电磁信号的功率与待充电设备内电池当前所需的充电电压和/或充电电流相匹配。
在该无线充电装置进入第一无线充电模式对待充电设备进行充电后，进一步地，该无线充电装置可以与该待充电设备进行无线通信，以便无线充电装置调整无线发射电路的发射功率。换句话说，该无线充电装置的发射功率可以基于待充电设备的反馈信息进行调节。待充电设备可以通过其内部的检测电路实时检测加载在电池两端的充电电压和充电电流是否与当前电池所处的充电阶段是否匹配。若不匹配，可以向无线充电装置反馈，例如，可以反馈充电电压不匹配和/或充电电流不匹配等。
作为一个可选地示例，该待充电设备可以向该无线充电装置发送调整信息，以指示该无线充电装置调整无线发射电路的发射功率。例如，该调整信息可以指示该无线充电装置增大无线发射电路的发射功率；又如，该调整信息可以指示该无线充电装置减小该无线发射电路的发射功率。更为具体地，无线充电装置可以为无线发射电路设置发射功率的多个档位，无线充电装置每接收到一次调整信息，就将无线发射电路的发射功率的档位调整一格，直到待充电设备中的无线接收电路的输出电压和/或输出电流与电池当前所需的充电电流和/或充电电压相匹配。
除了上述通信内容之外，无线充电装置与待充电设备之间还可以交互许多其他通信信息。在一些实施例中，无线充电装置与待充电设备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和无线接收电路之间的功率传输效率)。
例如，当电池的温度过高时，无线充电装置和/或待充电设备可以控制充电回路进入保护状态，如控制充电回路停止无线充电。又如，无线充电装置接收到待充电设备发送的过压保护或过流保护的指示信息之后，无线充电装置可以降低发射功率，或控制无线充电装置停止工作。又如无线充电装置接收到待充电设备发送的功率传输效率信息之后，如果功率传输效率低于预设阈值，可以控制无线充电装置停止工作，并向用户通知这一事件，如通过显示屏显示功率传输效率过低，或者可以通过指示灯指示功率传输效率过低，以便用户调整无线充电的环境。
本申请实施例对无线充电装置与待充电设备之间的无线通信方式不做具体限定。举例说明，无线充电装置和待充电设备可以基于蓝牙(bluetooth)、无线保真(wireless fidelity，Wi-Fi)或反向散射(backscatter)调制方式(或功率负载调制方式)进行无线通信。
电池的充电过程包括涓流充电阶段、恒压充电阶段、恒流充电阶段中的至少一个。
可示例地，在电池的涓流充电阶段，该无线充电装置发射的电磁信号的功率与涓流充电阶段对应的充电电流相匹配。换句话说，在电池的涓流充电阶段，该无线充电装置调整无线发射电路的发射功率，使得无线接收电路的输出电流与涓流充电阶段对应的充电电流相匹配(或者，使得无线接收电路的输出电流满足电池在涓流充电阶段对充电电流的需求)。
以涓流充电阶段对应的充电电流等于1A为例进行说明。当电池处于涓流充电阶段时，待充电设备可以实时检测无线接收电路的输出电流。当无线接收电路的输出电流大于1A时，待充电设备可以与无线充电装置进行通信，以便无线充电装置调整无线发射电路的发射功率，使得无线接收电路的输出电流重新回到1A。
可示例地，在电池的恒压充电阶段，该无线充电装置发射的电磁信号的功率与恒压充电阶段对应的充电电压相匹配。换句话说，在电池的恒压充电阶段，该无线充电装置 调整无线发射电路的发射功率，使得无线接收电路的输出电压与恒压充电阶段对应的充电电流相匹配(或者，使得无线接收电路的输出电压满足电池在恒压充电阶段对充电电压的需求)。
以恒压充电阶段对应的充电电压等于5V为例进行说明。当电池处于恒压充电阶段时，待充电设备可以实时检测无线接收电路的输出电压。当无线接收电路的输出电压低于5V时，待充电设备可以与无线充电装置进行通信，以便无线充电装置调整无线发射电路的发射功率，使得无线接收电路的输出电压重新回到5V。
可示例地，在电池的恒流充电阶段，该无线充电装置发射的电磁信号的功率与恒流充电阶段对应的充电电流相匹配。换句话说，在电池的恒流充电阶段，该无线充电装置调整无线发射电路的发射功率，使得无线接收电路的输出电流与恒流充电阶段对应的充电电流相匹配(或者，使得无线接收电路的输出电流满足电池在恒流充电阶段对充电电流的需求)。
以恒流充电阶段对应的充电电流等于2A为例进行说明。当电池处于恒流充电阶段时，待充电设备可以实时检测无线接收电路的输出电流。当无线接收电路的输出电流低于2A时，待充电设备可以与无线充电装置进行通信，以便无线充电装置调整无线发射电路的发射功率，使得无线接收电路的输出电流重新回到2A。
无线接收电路的输出电流变化的原因可能有多种，本申请实施例对此不做具体限定。例如，无线发射电路与无线接收电路之间的电磁信号的传输受到干扰，导致能量转换效率降低，从而导致无线接收电路的输出电流不足2A。
需要说明的是，本申请实施例中提及的恒流充电阶段或恒流阶段并非要求充电电流保持完全恒定不变，例如可以是泛指充电电流的峰值或均值在一段时间内保持不变。实际中，恒流充电阶段通常采用分段恒流的方式进行充电。
分段恒流充电(Multi-stage constant current charging)可具有N个恒流阶段(N为一个不小于2的整数)，分段恒流充电以预定的充电电流开始第一阶段充电，该分段恒流充电的N个恒流阶段从第一阶段到第N个阶段依次被执行，当恒流阶段中的前一个恒流阶段转到下一个恒流阶段后，脉动波形的电流峰值或平均值可变小；当电池电压到达充电终止电压阈值时，恒流阶段中的前一个恒流阶段会转到下一个恒流阶段。相邻两个恒流阶段之间的电流转换过程可以是渐变的，或，也可以是台阶式的跳跃变化。
应理解，本申请实施例中所使用到的待充电设备可以是指终端，该“终端”可包括，但不限于被设置成经由有线线路连接(如经由公共交换电话网络(public switched telephone network，PSTN)、数字用户线路(digital subscriber line，DSL)、数字电缆、直接电缆连接，以及/或另一数据连接/网络)和/或经由(例如，针对蜂窝网络、无线局域网(wireless local area network，WLAN)、诸如手持数字视频广播(digital video broadcasting handheld，DVB-H)网络的数字电视网络、卫星网络、调幅-调频(amplitude modulation-frequency modulation，AM-FM)广播发送器，以及/或另一通信终端的)无线接口接收/发送通信信号的装置。被设置成通过无线接口通信的终端可以被称为“无线通信终端”、“无线终端”以及/或“移动终端”。移动终端的示例包括，但不限于卫星或蜂窝电话；可以组合蜂窝无线电电话与数据处理、传真以及数据通信能力的个人通信系统(personal communication system，PCS)终端；可以包括无线电电话、寻呼机、因特网/内联网接入、Web浏览器、记事簿、日历以及/或全球定位系统(global positioning system,GPS)接收器的个人数字助理(personal digital assistant，PDA)；以及常规膝上型和/或掌上型接收器或包括无线电电话收发器的其它电子装置。另外，本申请实施例中所使用到的待充电设备或终端还可包括移动电源(power bank)，该移动电源能够接收无线充电装置的充电，从而将能量存储起来，以为其他电子装置提供能量。
上文已经指出，本申请实施例提供的无线充电装置能够在第一无线充电模式下的充电过程中不断调整无线发射电路的发射功率，使得无线接收电路的输出电压和/或输出电流与电池当前所需的充电电压和/或充电电流相匹配。本申请实施例对无线发射电路的发 射功率的调整方式不做具体限定。
可选地，作为一个实施例，无线充电装置可以与电源提供设备进行通信，以调整电源提供设备的输出电压和/或输出电流，从而调整无线发射电路的发射功率。将无线发射电路的发射功率调整的控制权分配给电源提供设备，由电源提供设备通过改变输出电压和/或输出电流的方式对无线发射电路的发射功率进行调整。这种调整方式的优点在于无线充电装置需要多少功率，电源提供设备就提供多少功率，不存在功率的浪费。
可选地，作为另一个实施例，无线充电装置可以调整无线发射电路从电源提供设备提供的最大输出功率中抽取的功率量，从而调整无线发射电路的发射功率。也就是说，本申请实施例将无线发射电路的发射功率调整的控制权分配给无线充电装置，无线充电装置能够在接收到待充电设备的反馈信息之后立刻对无线发射电路的发射功率进行调整，具有调节速度快、效率高的优点。
而在第二无线充电模式下，作为一个可选地实施例，电源提供设备可以是最大输出功率为固定的电源提供设备，并且无线充电装置对电源提供设备输出的功率不作调整，使用固定的发射功率对待充电设备进行充电。例如，电源提供设备可以输出固定的5W，使得无线充电装置采用固定的5W的功率对待充电设备进行无线充电。作为另一可选地实施例，电源提供设备也可以输出大于5W的最大输出功率，无线充电装置将该电源提供设备提供的最大输出功率变换到固定的5W对待充电设备进行无线充电。无论该无线充电装置是否对电源提供设备输出的最大输出功率进行调整，在第二无线充电模式下，该电源提供设备的最大输出功率都是小于预设值。
在无线充电装置识别到电源提供设备的类型之后，进一步地，无线充电装置可以向待充电设备提供该电源提供设备的类型，进而待充电设备可以根据该电源提供设备的类型进入到相应的无线充电模式。例如，若该电源提供设备为快充电源提供设备，则该待充电设备可以进入第一无线充电模式；若该电源提供设备为普通电源提供设备，则该待充电设备可以进入第二无线充电模式。
可选地，在一些实施例中，可以在无线充电装置与电源提供设备相连后，无线充电装置主动识别该电源提供设备的类型，当无线充电装置检测到待充电设备时，无线充电装置就可以向该待充电设备提供电源提供设备的类型。
可选地，在一些实施例中，可以在无线充电装置与电源提供设备相连后，无线充电装置等待待充电设备的请求指令，也就是说，在待充电设备进入无线充电装置的充电区域后，例如可以在接收到无线充电装置发射的电磁信号后，向无线充电装置发送请求指令，该请求指令用于请求无线充电装置提供电源提供设备的类型，无线充电装置可以根据该请求指令识别电源提供设备的类型，并向待充电设备发送该电源提供设备的类型。
可选地，在无线充电装置检测到待充电设备后，无线充电装置可以先使用第二无线充电模式下对待充电设备进行充电，换句话说，无线充电装置可以先向待充电设备提供标准的无线充电电压和电流(例如QI标准的5W)，在识别到电源提供设备的类型之后，无线充电装置再采用与电源提供设备的类型相匹配的无线充电模式对待充电设备提供无线充电电压和电流。
本申请实施例对无线充电装置与电源提供设备之间的通信方式不作限定。作为一个示例，该无线充电装置可以通过除充电接口之外的其他通信接口与电源提供设备相连，并通过该通信接口与电源提供设备通信。作为另一个示例，该无线充电装置可以以无线的方式与电源提供设备进行近场通信(near field communication，NFC)。作为又一示例，该无线充电装置可以通过充电接口与电源提供设备进行通信，而无需设置额外的通信接口。例如，充电接口可以为USB接口，该无线充电装置可以通过该USB接口中的数据线(如D+和/D-线)进行通信。具体地，无线充电装置可以通过该USB接口中的数据线识别电源提供设备的类型。又如，该充电接口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)，无线充电装置与电源提供设备可以基于PD通信协议进行通信。
应理解，本申请实施例对电源提供设备的类型不作具体限定。例如，电源提供设备可以是适配器、移动电源、车载充电器或电脑等设备。具体地，电源提供设备的类型可以包括两类，一种可以对应上述第一无线充电模式，另一种可以对应上述第二无线充电模式。例如，与第一无线充电模式对应的电源提供设备的类型可以是快充适配器(提供的最大输出功率大于或等于预设值)，而与第二无线充电模式对应的电源提供设备的类型可以是标准适配器或USB接口(提供的最大输出功率小于一定预设值)。
还应理解，电源提供设备的输出电流可以为恒定直流电、脉动直流电或交流电，本申请实施例对此不做具体限定。
还应理解，图2的例子仅仅是为了帮助本领域技术人员理解本申请实施例，而非将本申请实施例限于所例示的具体场景。本领域技术人员根据所给出的图2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申请实施例的范围内。
下面将结合图6描述本申请另一实施例的无线充电方法500。如图6所示，该方法500可以由待充电设备(如图5中的待充电设备)执行。该待充电设备例如可以是终端，该方法500可以包括以下部分或全部内容：
S510，该待充电设备接收该无线充电装置提供的与该无线充电装置相连的电源提供设备的类型。
S520，当该电源提供设备为快充类电源提供设备时，该待充电设备进入第一无线充电模式为该待充电设备的电池充电；当该电源提供设备为普通类电源提供设备时，该无线充电装置进入第二无线充电模式为该电池充电。
