目前,在充电技术领域,待充电设备主要采用有线充电方式进行充电。具体地,以手机为例,当需要为手机充电时,可以通过有线线缆(如通用串行总线(universal serial bus,USB)线缆)将手机与电源提供设备相连,并通过该充电线缆将电源提供设备的输出功率传输至手机,为手机内的电池充电。
对待充电设备而言,有线充电方式需要使用充电线缆,导致充电准备阶段的操作繁琐。因此,无线充电方式越来越受到人们的青睐。
但目前的无线充电装置无法识别快充适配器,使得目前的无线充电方式仅限于标准充电方式,具有快速充电功能的待充电设备也只能在标准充电方式下进行无线充电,充电时间较长,导致用户体验较差。

下面将结合附图,对本申请实施例中的技术方案进行描述。
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***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120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。
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。
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,无线充电装置只适用标准的电源提供设备,只能对待充电设备提供标准的无线充电电压和电流(如QI标准中的5W充电模式),使得充电时间过长。而在电源提供设备具有快充功能时,例如电源提供设备为快充适配器,由于待充电设备无法识别其快充功能时,仍然只能对待充电设备提供标准的无线充电方式,这样不能充分利用该快充功能进行无线充电,从而导致用户体验较差。
为了解决上述问题,本申请实施例提供了一种无线充电装置,在该无线充电装置未连接待充电设备时,也可以识别该无线充电装置连接电源提供设备的类型,例如,该电源提供设备是否为快充电源提供设备,这样,在该无线充电装置识别出具有快充功能的电源提供设备时,可以选择采用快充的充电方式对待充电设备进行充电。
图2示出了根据本申请实施例的无线充电装置200的示意性框图。如图2所示,该无线充电装置200包括:通信控制模块210。具体地,该无线充电装置200可以与电源提供设备相连,例如,可以通过充电接口与电源提供设备相连,该通信控制模块210用于:当电源提供设备处于休眠状态时,控制该电源提供设备进入唤醒状态;并与处于该唤醒状态的该电源提供设备通信,以确定该电源提供设备的类型,其中,该电源提供设备的类型包括快充类和非快充类,该快充类的电源提供设备的最大输出功率大于或者等于预设值,该非快充类的电源提供设备的最大输出功率小于所述预设值。
在本申请实施例中,无线充电装置200可以通过充电接口与电源提供设备相连,该无线充电装置200中有电源供电时,即该无线充电装置200中有电流通过,则可以确定充电接口210连接有电源提供设备。
应理解,为了降低功耗,电源提供设备在没有连接负载时,输出电流比较小,即小于预设值,即该电源提供设备处于休眠状态。具体地,在该无线充电装置200连接了电源提供设备时,若该无线充电装置200未向待充电设备充电,该电源提供设备输出电流较小,该电源提供设备处于休眠状态,其中,电源提供设备的输出电流小于预设值。可选地,该预设值可以根据实际应用设置,例如,该电源提供设备在没有负载时,输出电流通常小于100mA,由于该电流不稳定,考虑到波动或误差因素,对应地,一般可以该预设值设置为大于100mA,例如可以设置为300mA。
当该电源提供设备处于休眠状态时,为了获取该电源提供设备的类型,无线充电装置200可以通过通信控制模块210控制该电源提供设备退出该休眠状态,进入唤醒状态,以便于该通信控制模块210确定该电源提供设备的类型,即确定该电源提供设备为快充电源提供设备或非快充电源提供设备。
具体地,该通信控制模块210可以通过增加负载电流,使得该电源提供设备的输出电流大于或者等于预设值,从而使得处于休眠状态的电源提供设备进入唤醒状态。例如,该无线充电装置200可以包括负载电路,通信控制模块210与该负载电路相连,该通信控制模块210控制该负载电路断开时,即使得电源提供设备没有连接该负载电路时,则该电源提供设备处于休眠状态;当通过该通信控制模块210控制闭合负载电路时,即电路提供设备连接该负载电路,使得该电源提供设备的输出电流大于或者等于预设值,则电源提供设备从休眠状态进入唤醒状态。
可选地,该负载电路可以包括电阻,还可以包括开关,该通信控制模块210通过控制该开关断开或闭合该负载电路与电源提供设备之间的连接,其中,该电阻的大小可以根据实际应用设置,例如,该电阻可以为12Ω。
应理解,该通信控制模块210将电源提供设备从休眠状态唤醒后,可确定该电源提供设备的类型。具体地,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。
以无线充电装置200与电源提供设备之间可以通过充电接口210连接以及通信为例,该充电接口210可以为USB接口或lightning接口,以该充电接口210为USB接口为例,该无线充电装置200与电源提供设备之间通过USB连接线上的数据线进行通信。
例如,无线充电装置200的通信控制模块210通过USB连接线上的数据线(D+和/或D-线),询问电源提供设备的类型是否为快充电源提供设备,若得到电源提供设备的正确回复,则确定该电源提供设备为快充电源提供设备;若的到错误回复或者没有回复,则确定该电源提供设备为非快充电源提供设备。具体地,无线充电装置200可以向电源提供设备发送询问信息,若接收到该电源提供设备发送的正确的回复信息,即该回复信息指示该电源提供设备为快充类的电源提供设备,例如可以将正确的回复信息设置为“01”,则接收到回复信息为“01”时表示该电源提供设备的类型为快充类;相反的,若没有接收到该电源提供设备发送的回复信息或接收的回复信息错误,即该回复信息指示该电源提供设备为非快充类的电源提供设备,例如可以将正确的回复信息设置为“01”,则接收到回复信息不是“01”时表示该电源提供设备的类型为非快充类。
再例如,该充电接口还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,本申请实施例并不限于此。
应理解,本申请实施例对电源提供设备的种类不作具体限定。例如,电源提供设备可以是适配器、移动电源或电脑等设备。具体地,电源提供设备的类型可以包括两类,一种可以对应第一无线充电模式的快充类,该快充类电源提供设备的最大输出功率大于或者等于预设值;另一种可以对应第二无线充电模式的非快充类,该快充类电源提供设备的最大输出功率小于预设值。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,该快充适配器支持快充功能,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电脑的USB接口,该标准适配器不支持快充功能。
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。
在本申请实施例中,无线充电装置200通过该通信控制模块210获得该电源提供设备的类型之后,由于该无线充电装置200还未连接待充电设备,因此可以控制该电源提供设备的输出电流小于预设值,使得该电源提供设备退出唤醒状态,重新进入休眠状态,从而降低功耗。具体地,该无线充电装置200可以令负载电路断开,使得电源提供设备的输出电流降低至小于预设值,进入休眠状态。
进一步的,图3示出了根据本申请实施例的无线充电装置的另一示意性框图,如图3所示,在本申请实施例中,该无线充电装置200还可以包括充电接口220,还可以包括无线发射电路230,具体地,无线充电装置200获取该电源提供设备的类型后,在该无线充电装置200连接待充电设备时,该无线发射电路230可以用于:当该电源提供设备为快充电源提供设备时,在第一无线充电模式下发射电磁信号,以对待充电设备的电池进行充电;或当该电源提供设备为非快充电源提供设备时,在第二无线充电模式下发射电磁信号,以对该电池进行充电;其中,该无线发射电路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发射电路在该第二无线充电模式下对该电池的充电速度。
另外,在无线充电装置200识别到电源提供设备的类型之后,进一步地,无线充电装置200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。
需要说明的是,在本申请实施例中,该无线充电装置200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,其中,无线充电装置200在第一无线充电模式下对待充电设备的充电速度大于无线充电装置200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装置来说,工作在第一无线充电模式下的无线充电装置200充满相同容量的待充电设备中的电池的耗时更短。
应理解,当电源提供设备为非快充电源提供设备时,也就是该非快充电源提供设备的最大输出功率小于预设值时,对应的第二无线充电模式可为称为普通无线充电模式。相对的,当电源提供设备为快充电源提供设备时,也就是该快充电源提供设备的最大输出功率大于或者等于预设值时,对应的第一无线充电模式可为快速无线充电模式。
应理解,该预设值可以根据实际应用进行设置,本申请实施例并不限于此。
在本公开的一实施例中,如图4所示,无线充电装置200还包括:电压转换电路240。该电压转换电路240用于在提供给无线发射电路230的电流的电压不满足预设条件时,对提供给无线发射电路230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230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230的电压可以达到无线发射电路230对输入电压的电压需求,可以省去电压转换电路240,以简化无线充电装置的实现。无线发射电路230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230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230的需求电压,或者,该电压高于无线发射电路的需求电压。例如,无线充电装置200识别电源提供设备的类型为非快充类,若该无线充电装置200仍然采用前述第一充电模式进行无线充电,由于这种充电模式对无线发射电路230的输入电压要求较高(如电压需求为10V或20V)。如果提供给无线发射电路230的电压无法达到无线发射电路230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240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230的电压需求。
相反的,若无线充电装置200识别电源提供设备的类型为快充类,若该无线充电装置200仍然采用前述第二充电模式进行无线充电,也就是电源提供设备的输出电压超过无线发射电路230的电压需求,电压转换电路240可以对输入电压进行降压,以使得降压后的电压达到无线发射电路230的电压需求。
由此,在电源提供设备为非快充电源提供设备时,通过电压转换电路240依然可实现采用第一充电模式对待充电设备进行充电;或者,电源提供设备为快充电源提供设备时,通过电压转换电路240依然可实现采用第二充电模式对待充电设备进行充电,这样,即可以提高充电速度,也使得无线发射装置200的兼容性。
其中,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,对应的非快充类的电源提供设备的最大输出功率可以设置为该固定功率,或者将非快充类的电源提供设备的发射功率设置为该固定功率,例如设置为小于15W,常用的可以设置为5W或10W,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,对应的快充类的电源提供设备的最大输出功率可以设置为较大的功率值,例如设置为大于15W的值,例如可以设置为20W。具体地,可以将快充类的电源提供设备的发射功率设置为可调的功率,或者将快充类的电源提供设备的发射功率设置为固定的功率。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。
本申请实施例中的无线充电装置200不同于传统的无线充电装置,可以与待充电设备之间进行无线通信。具体地,在电源提供设备与本申请实施例的无线充电装置200相连之后,该无线充电装置200可以识别电源提供设备的类型,进而无线充电装置200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电源提供设备,则无线充电装置200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电源提供设备,则无线充电装置200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,在一些实施例中,在第一无线充电模式下,该无线充电装置200通过无线发射电路230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。本申请实施例对无线发射电路230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200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230的发射功率。将无线发射电路230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230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。
具体地,无线充电装置200可以主动确定是否需要调整电源提供设备的输出电压和/或输出电流。或者,无线充电装置200也可以作为电源提供设备和待充电设备之间通信的桥梁,主要负责在二者之间转发信息。
例如,在无线充电的过程中,通信控制模块210与待充电设备进行通信,以确定是否需要调整电源提供设备的输出电压和/或输出电流;在需要调整电源提供设备的输出电压和/或输出电流的情况下,通信控制模块210与电源提 供设备进行通信,以指示电源提供设备调整电源提供设备的输出电压和/或输出电流。
又如,在无线充电的过程中,无线充电装置200内部的通信控制模块210与待充电设备进行无线通信,获取调整信息,调整信息用于指示对电源提供设备的输出电压和/或输出电流进行调整;通信控制模块210与电源提供设备进行通信,将该调整信息发送至电源提供设备,以便电源提供设备根据调整信息调整电源提供设备的输出电压和/或输出电流。例如,该调整信息可以指示该电源提供设备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电源提供设备减小该无线发射电路的发射功率。更为具体地,电源提供设备可以设置发射功率的多个档位,电源提供设备每接收到一次调整信息,就将其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处的充电阶段相匹配。
可选地,作为另一个实施例,无线充电装置200还可以调整无线发射电路230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230的发射功率。也就是说,本申请实施例将无线发射电路230的发射功率调整的控制权分配给无线充电装置200,无线充电装置200能够在接收到待充电设备的调整信息之后立刻对无线发射电路230的发射功率进行调整,具有调节速度快、效率高的优点。
具体地,在该无线充电装置200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200可以与该待充电设备进行无线通信,以便无线充电装置200根据待充电电池的需求调整无线发射电路230的发射功率。换句话说,电源提供设备的输出功率一定,该无线充电装置200的发射功率可以基于待充电设备的反馈的调整信息进行调节。
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200发送调整信息,以指示该无线充电装置200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200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200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200可以为无线发射电路230设置发射功率的多个档位,无线充电装置200每接收到一次调整信息,就将无线发射电路230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处的充电阶段相匹配。
而在第二无线充电模式下,电源提供设备可以是输出功率固定的普通的电源提供设备,并且无线充电装置200对电源提供设备输出的功率也不作调整,使用固定的发射功率对待充电设备进行充电。
在本申请实施例中,除了上述通信内容之外,无线充电装置200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200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200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***(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***(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),该移动电源能够接受适配器的充电,从而将能量存储起来,以为其 他电子装置提供能量。
