本申请涉及电子设备领域,并且更具体地,涉及一种无线充电的方法、设备以及***。
无线充电技术可以方便电子设备充电。当电子设备的充电线圈与无线充电器对齐后,无线充电底座发射的磁信号可以使该充电线圈产生感应电流,进而可以为电子设备的电池充电。
在无线充电技术的基础上又发展出无线反向充电技术。也就是说,具有无线充电功能的电子设备可以为其他具有无线充电功能的电子设备充电。例如,电子设备1的电池1可以为充电线圈1供电并产生磁信号,电子设备1的充电线圈1可以与电子设备2的充电线圈2对齐,从而充电线圈1产生的磁信号可以使电子设备2的充电线圈2产生感应电流,进而电子设备1可以为电子设备2的电池2充电。作为提供电能的一方,电子设备1的无线充电性能应当被关注。
发明内容
本申请提供一种无线充电的方法、设备以及***,目的是提升电子设备的无线充电性能。
第一方面,提供了一种无线充电的方法,包括:
供电设备通过无线充电芯片,向电力接收设备发送充电状态请求数据包,所述充电状态请求数据包用于请求所述电力接收设备的n个充电状态信息;
所述供电设备通过所述无线充电芯片,从所述电力接收设备接收充电状态反馈数据包,所述充电状态反馈数据包包括所述n个充电状态信息,
其中,所述n个充电状态信息包括以下至少一项:充电电压、充电电流、充电内阻、当前电量、充电输入功率、充电温度、电池健康指数、当前工作频率、电池总容量、充放电循环次数、无线充电能效比、设备标识,n为大于或等于1的整数。
在本申请中,供电设备可以通过无线充电芯片与电力接收设备交互该电力接收设备的充电状态信息,有利于减少在供电设备与电力接收设备交互过程中涉及到的硬件数量,有利于减小无线充电过程中不必要的耗能。另外,供电设备获取到电力接收设备的充电状态 信息,有利于合理调整无线充电模式,进而有利于提升供电设备的使用性能以及电力接收设备的充电性能。
结合第一方面,在第一方面的某些实现方式中,在所述电力接收设备的充电状态信息满足第一预设条件的情况下,所述方法还包括:
所述供电设备降低充电输出功率。
在本申请中,供电设备可以根据电力接收设备的充电状态信息,判断是否有必要为电力接收设备无线(反向)充电,或者可以判断电力接收设备的电池是否可能存在充电隐患。供电设备可以通过逐级减小充电输出功率的方式,提升无线反向充电的安全性,进而有利于兼顾无线反向充电功能以及无线反向充电安全。逐级减小充电输出功率的方式通常可以具有相对较强的灵活性。
结合第一方面,在第一方面的某些实现方式中,在所述电力接收设备的充电状态信息满足第一预设条件的情况下,所述方法还包括:
所述供电设备停止为所述电力接收设备无线反向充电。
在本申请中,供电设备可以根据电力接收设备的充电状态信息,判断是否有必要为电力接收设备无线反向充电,或者可以判断电力接收设备的电池是否可能存在充电隐患。供电设备可以通过自动停充的方式,提升无线反向充电的安全性,进而有利于兼顾无线反向充电功能以及无线反向充电安全。自动停充的方式通常可以具有相对较高的安全性。
结合第一方面,在第一方面的某些实现方式中,所述第一预设条件包括以下至少一项:
所述电力接收设备的当前电量大于预设停充电量;
所述电力接收设备的充电温度大于预设充电温度;
所述电力接收设备的无线充电能效比小于预设能耗比;
所述电力接收设备的电池健康指数小于预设健康分数;
所述电力接收设备的设备标识属于设备黑名单。
在电力接收设备的剩余电量相对足够的情况下,电力接收设备的待机时间可以相对较长。通过关闭无线反向充电功能或降低充电输出功率,可以降低供电设备的耗电量,进而有利于提升供电设备的待机时间。
如果电力接收设备的充电温度越高,电力接收设备的电池342存在充电隐患的概率越大。通过关闭无线反向充电功能或降低充电输出功率,有利于兼顾无线反向充电功能以及无线反向充电安全。
“无线充电能效比小于预设能耗比”可以对应“反向充电输出功率与充电输入功率的差值大于预设功率”。如果反向充电输出功率与充电输入功率的差值大于预设功率,可以意味着无线反向充电过程中的电能损耗相对较大,可能的原因例如可以是漏电等,即可能存在安全隐患。通过关闭无线反向充电功能或降低充电输出功率,有利于提高无线反向充电的安全性。另外,在一些可能的场景中,电力接收设备向供电设备反馈功率,目的通常是指示供电设备提供合适的无线反充功率,例如在电力接收设备电量即将充满时,电力接收设备可以向供电设备发送功率指示信息,指示供电设备降低输出功率。但是这一功率指示信息并不能反映电力接收设备实际接收到的功率,也无法反映无线反向充电过程中是否存在安全隐患。
如果电池健康状态对应的分数低于预设健康分数,则供电设备可以判断电力接收设备 的电池当前处于非健康充电状态。通过关闭无线反向充电功能或降低充电输出功率,有利于提高无线反向充电的安全性。
电力接收设备的充电性能可能会严重影响供电设备的使用性能。通过判断电力接收设备的设备标识是否属于设备黑名单,有利于维持供电设备的使用性能。

结合第一方面,在第一方面的某些实现方式中,所述方法还包括:

当蓝牙耳机放置在耳机盒内时,蓝牙耳机通常处于关机状态,蓝牙耳机通常无法通过蓝牙通信模块与周围设备交互。通过无线充电芯片交互蓝牙耳机的充电状态信息,使得用户可以通过供电设备获知蓝牙耳机的充电状态,进而有利于提高蓝牙耳机在无线充电过程中的用户体验感。
结合第一方面,在第一方面的某些实现方式中,所述方法还包括:
所述供电设备向监控设备发送所述电力接收设备的充电状态信息以及所述供电设备的充电状态信息;
所述供电设备从所述监控设备接收指示信息,所述指示信息指示所述供电设备调整充电输出功率,或停止为所述电力接收设备无线反向充电。
用户可以通过监控设备获知供电设备与电力接收设备之间的无线充电状况。这样有利于减少无线充电被打断的次数(因为用户不需要切断供电设备与电力接收设备之间的无线充电关系,就可以了解当前无线充电状态)。另外,还有利于减少供电设备、电力接收设备在无线充电过程中的电量消耗。并且,用户可以通过监控设备控制供电设备调整无线充 电模式,具有较强的灵活性。
结合第一方面,在第一方面的某些实现方式中,在所述供电设备的充电状态信息满足第二预设条件的情况下,所述方法还包括:
所述供电设备降低充电输出功率,或停止为所述电力接收设备无线反向充电。
在本申请中,供电设备可以根据供电设备的充电状态信息,判断是否有必要为电力接收设备无线反向充电。供电设备可以通过自动停充或降低充电输出功率的方式,提升供电设备的待机时间,也有利于维持供电设备的其他元器件的正常工作。
结合第一方面,在第一方面的某些实现方式中,所述第二预设条件包括以下至少一项:
所述供电设备的当前电量达到或小于本机停充电量;
所述供电设备的单次耗电量达到或大于单次耗电限量。
在供电设备自身的剩余电量不足的情况下,供电设备可以通过关闭无线反向充电功能或降低充电输出功率,来降低自身的耗电量,进而有利于提升供电设备的待机时间。
在供电设备自身电量消耗过大的情况下,供电设备可以通过关闭无线反向充电功能或降低充电输出功率,来降低自身的耗电量,进而有利于提升供电设备的待机时间,也有利于维持供电设备的其他元器件的正常工作。
结合第一方面,在第一方面的某些实现方式中,所述方法还包括:
所述供电设备显示第二参数控件;
所述供电设备响应作用于所述第二参数控件的操作,修改以下任一项参数:所述本机停充电量、所述单次耗电限量。
显示界面可以包括参数控件。用户可以通过作用在参数控件上的一系列手势操作,调整供电设备降低充电输出功率或自动停充的预设条件。本申请提供的方法具有相对较优的用户体验感。
结合第一方面,在第一方面的某些实现方式中,所述充电状态请求数据包包括与所述n个充电状态信息一一对应的n个命令符,所述n个命令符承载于所述充电状态请求数据包的报头或报文中。
通过约定与充电状态信息对应的命令符,有利于节省无线充电数据包的开销。

通过约定与某一类充电状态信息对应的命令符,有利于节省无线充电数据包的开销。
结合第一方面,在第一方面的某些实现方式中,所述第一类充电状态信息为动态充电状态信息或静态充电状态信息。
在一次无线充电过程中,静态充电状态信息通常不会发生明显的变化,因此将静态充电状态信息与动态充电状态信息区分开,有利于节省无线充电数据包的开销。
结合第一方面,在第一方面的某些实现方式中,所述充电状态请求数据用于指示目标周期,所述目标周期为所述n个充电状态信息的反馈周期。
通过约定充电状态信息的反馈周期,有利于节省无线充电数据包的开销。
结合第一方面,在第一方面的某些实现方式中,所述充电状态请求数据包、所述充电 状态反馈数据包均为无线充电Qi协议的数据包。
无线Qi协议与蓝牙协议、无线局域网协议不同。在供电设备为电力接收设备无线反向充电的过程中,供电设备与电力接收设备之间始终需要通过无线Qi协议进行交互,以维持正常的无线充电状态。而蓝牙协议、无线局域网协议对于供电设备、电力接收设备而言不是必须使用的。如果电力接收设备不具有蓝牙功能、无线局域网功能,电力接收设备将无法通过蓝牙协议或无线局域网协议,向供电设备提供电力接收设备的充电状态信息。那么,供电设备的使用性能可以被降低。
另外,开启短距离通信功能的数量越多,电子设备的耗电量也就越大(需要时刻维持蓝牙链接或无线局域网链接),这样更加难以兼顾耗电量与无线充电性能。
并且,通过蓝牙协议、无线局域网协议等传输充电状态信息,会涉及到多个模块(例如蓝牙射频模块、存储器、处理器、无线充电芯片、电池等模块)之间的交互、配合(例如需要将蓝牙协议的数据包转换为无线Qi协议的数据包)。这可能会占用较多的数据处理资源。

如图3中的(d)所示,无线反向充电场景可以包括平板电脑307、手写笔308。其中,平板电脑307、手写笔308均可以具有无线充电功能。平板电脑307还可以开启无线反向充电功能。在手写笔308的无线充电区域与平板电脑307的无线充电区域对准后,手机可以给手写笔308无线充电。手写笔308可以不具有无线反向充电功能,或者,手写笔308可以暂不开启无线反向充电功能。
应理解,本申请实施例可以不限定无线反向充电场景中电子设备的具体类型。例如,供电设备(开启无线反向充电功能并给其他设备无线充电的电子设备)例如可以为手机、平板电脑、笔记本电脑等便携式电子设备。电力接收设备(被供电设备无线充电的电子设备)例如可以为手机、手环、手表、耳机、键盘、手写笔、电动牙刷等便携式电子设备。
下面结合图4阐述无线充电的工作原理。
在无线充电场景中,存在供电设备410和电力接收设备420,其中供电设备410、电力接收设备420均可以具有无线充电能力。供电设备410还可以具有无线反向充电能力。供电设备410例如可以为图3所示的手机301、手机303、第一手机305、平板电脑307。电力接收设备420例如可以为图3所示的手表302、蓝牙耳机304、第二手机306、手写笔308。供电设备410和电力接收设备420的硬件单元和软件结构可以参照图1、图2所示的电子设备100。
供电设备410例如可以包括电池242、无线充电芯片143(无线充电芯片143例如可以对应图1所示的电源管理模块141和/或充电管理模块140),以及无线充电线圈132。电力接收设备420例如可以包括电池342、无线充电芯片243,以及无线充电线圈232。
供电设备410可以通过无线充电芯片143,控制电池242向无线充电线圈132输出电流,从而,无线充电线圈132可以发射高频磁场。在供电设备410的无线充电线圈132与电力接收设备420的无线充电线圈232配对的情况下,该高频磁场可以穿过无线充电线圈232,使得无线充电线圈232上可以产生感应电流。无线充电芯片243可以检测该感应电流,并将该感应电流输入至电池342。
除此以外,通过例如无线充电协议(无线Qi协议),还可以实现无线充电芯片143与无线充电芯片243之间的交互。无线Qi协议的数据包可以通过无线充电线圈132与无线充电线圈232之间的磁场媒介传输。
在一个可能的示例中,电池342的电量不同,电池342的充电功率也可能不同。在电池342处于正常充电状态(在该状态下,电池342的电量尚未充满,且电池342的电量相对较小)时,无线充电线圈232需要产生的感应电流通常相对较大。在电池342处于或接近电量充满状态时,无线充电线圈232需要产生的感应电流通常相对较小。无线充电芯片143可以通过无线充电线圈132,向无线充电芯片243发送无线Qi协议的数据包,该数据包可以用于请求电池342的无线充电功率;无线充电芯片243可以通过无线充电线圈232接收该数据包,并将电池342的无线充电功率通过无线Qi协议反馈给无线充电芯片143。无线充电芯片143可以调整无线充电线圈132的输出功率,以匹配电池342的无线充电功率。
虽然无线充电芯片243可以通过无线Qi协议向无线充电芯片143指示无线充电功率,该无线充电功率可以反映被充电池342的无线充电需求。然而,无线充电功率并不能反映被充电池342的实际的无线充电状态(例如无线充电功率无法反映被充电池342的无线充电状态是否健康、安全)。另外,被充电池342的充电状态也可能影响供电设备410的无线充电性能,进而影响供电设备410的用户体验。为此,本申请实施例提供一种新的无线Qi协议的数据包格式,从而有利于在无线充电场景中实现更加灵活的交互。
下面结合图5,阐述本申请实施例提供的一种无线Qi协议的数据包格式。
无线Qi协议的数据包可以包括前导码(preamble)、报头(header)、报文(message)、校验和(checksum)。前导码可以包括n个比特位,其中例如11≤n≤22。前导码可以用于同步两个电子设备的无线充电芯片,还可以用于确定报头的起始位置。报头可以用于指示无线Qi协议的数据包类型,还可以用于指示报文的数据量或报文的长度。报文可以包括多个字节,可以用于指示数据包的具体内容。校验和可以用于校验数据包是否传输错误。校验和的计算公式例如可以为:
其中,H可以指报头,B0,B1,……,Bn分别为报文中的字节,
可以指异或运算。
下面结合图6,阐述本申请实施例提供的一种无线充电的方法。图6所示的方法可以实现供电设备410与电力接收设备之间的交互。
601,供电设备410向电力接收设备420发送充电状态请求数据包,充电状态请求数据包用于请求n个充电状态信息,n为大于或等于1的整数,所述充电状态请求数据包为无线Qi协议的数据包。
相应地,电力接收设备420从供电设备410接收所述充电状态请求数据包。
结合图4、图5可知,供电设备410例如可以通过无线Qi协议,通过无线充电芯片143,向电力接收设备420的无线充电芯片243发送充电状态请求数据包。该充电状态请求数据包的报头和/或报文可以用于请求电力接收设备420的充电状态信息,其中充电状态信息例如可以包括充电电压(voltage)、充电电流(current)、充电内阻(tbat)、当前电量(capacity,soc)、充电输入功率、充电温度(temperature,tbat)、电池健康状态(例如被充电池342的健康指数)、当前工作频率、电池总容量(full charge capacity,FCC)、充放电循环次数(cycle)、无线充电能效比(ratio)、设备标识等中的一个或多个。充电电压例如可以包括以下至少一项:充电前端电压(vbus)、电池端电压(vbat)。充电电流可以包括以下至少一项:充电前端电流(ibus)、电池端电流(ibat)。设备标识例如可以包括以下至少一项:设备类型、设备子型号。
可选的,所述充电状态请求数据包包括n个命令符,所述n个充电状态信息与所述n个命令符一一对应。
也就是说,供电设备410可以通过n个命令符指示n个充电状态信息。例如,供电设备410与电力接收设备420可以事先约定好充电状态信息所对应命令符。又如,充电状态信息所对应命令符可以通过无线Qi协议规定。
在一个示例中,充电状态请求数据包例如可以包括第一报头、第一报文、第一校验和。充电状态请求数据包的格式例如可以如表一所示。
表一
第一报头可以用于指示第一报文的数据量(即第一报文所占用的字节数量)、数据包类型。例如,第一报头可以包括命令符“0x18”,“0x18”所指示的数据包类型例如可以为充电状态请求数据包,“0x18”所指示的第一报文的数据量可以为1个字节(1个字节可以包括8位,8位可以分别为b0、b1、b2、b3、b4、b5、b6、b7)。在其他示例中,第一报头还可以使用例如“0x28”、“0x38”、“0x19”、“0x29”、“0x39”等命令符。本申请实施例可以不限定第一报头采用的命令符的具体形式。
第一报文可以用于指示请求电力接收设备420的电池342的充电状态信息。可选的,第一报文可以包括一个或多个命令符(command,cmd),该一个或多个命令符可以与一个或多个充电状态信息一一对应。
例如,第一报文可以包括第一命令符、第二命令符、……、第n命令符,其中第一命令符可以与第一充电状态信息对应,第二命令符可以与第二充电状态信息对应,……,第n命令符可以与第n充电状态信息对应。
第一报文的命令符例如可以由“0xXX”表示,“0xXX”可以取值0x00~0xFF。例如,0x11可以与充电前端电压对应,0x12可以与电池端电压对应,0x13可以与充电前端电流对应,0x14可以与电池端电流对应,0x15可以与充电内阻对应,0x16可以与当前电量对应,0x17可以与无线反向充电输入功对应,0x18可以与充电温度对应,0x19可以与电池健康状态对应,0x20可以与当前工作频率对应,0x21可以与电池总容量对应,0x22可以与充放电循环次数对应,0x23可以与无线充电能效比对应,0x24可以与设备类型对应,0x25可以与设备子型号对应。应理解,本申请实施例可以不限定各个充电状态信息所对应的具体命令符。
充电状态请求数据包的编码方式例如可以为幅移键控(amplitude shift neying,ASN)。可选的,充电状态请求数据包的编码方式还可以为通断键控(On-Off Neying,OON)、频移键控(Frequency shift neying,FSN)和高斯频移键控(Gauss Frequency Shift Neying,GFSN)中的任一种。
602,电力接收设备420根据所述充电状态请求数据包,向供电设备410发送充电状态反馈数据包,所述充电状态反馈数据包包括所述n个充电状态信息,所述充电状态反馈数据包为无线Qi协议的数据包。
相应地,供电设备410从电力接收设备420接收所述充电状态反馈数据包。
在电力接收设备420接收到充电状态请求数据包后,该电力接收设备420可以获取电 力接收设备420的电池342的充电状态,并向供电设备410发送充电状态反馈数据包,以将电力接收设备420的电池342的充电状态反馈至供电设备410。当n的取值等于1时,供电设备410可以向电力接收设备420请求并获取单个充电状态信息。当n的取值大于1时,供电设备410可以向电力接收设备420请求并获取多个充电状态信息。
结合图4、图5可知,电力接收设备420例如可以通过无线Qi协议,通过无线充电芯片243,向供电设备410的无线充电芯片143发送充电状态反馈数据包。该充电状态反馈数据包的报头和/或报文可以用于反馈电力接收设备420的充电状态信息,其中充电状态信息例如可以包括充电电压、充电电流、充电输入功率、充电内阻、当前电量、充电温度、电池健康状态、电池总容量、充放电循环次数、无线充电能效比(即无线充电能量转换效率)、设备标识等中的一个或多个。
在一个示例中,充电状态反馈数据包例如可以包括第二报头、第二报文、第二校验和。充电状态反馈数据包的格式例如可以如表二所示。
表二
第二报头可以用于指示第二报文的数据量(即第二报文所占用的字节数量)、数据包类型。例如,第二报头可以包括命令符“0xnf”,“0xnf”所指示的数据包类型例如可以为充电状态反馈数据包,“0xnf”所指示的第二报文的数据量可以为n个字节(n个字节可以分别为B0、B1、……、Bn-1;每个字节可以包括8位,8位可以分别为b0、b1、b2、b3、b4、b5、b6、b7)。
第二报文例如可以包括电力接收设备420的电池342的一个或多个充电状态信息。如表二所示,第二报文可以包括第一充电状态信息、第二充电状态信息、……、第n充电状态信息。第一充电状态信息、第二充电状态信息、……、第n充电状态信息可以分别占用第二报文的n个字节。
充电状态反馈数据包的编码方式例如可以为频移键控(Frequency shift neying,FSN)。可选的,充电状态反馈数据包的编码方式还可以为通断键控(On-Off Neying,OON)、幅移键控(amplitude shift neying,ASN)和高斯频移键控(Gauss Frequency Shift Neying,GFSN)中的任一种。
可选的,所述充电状态请求数据包用于指示目标周期,所述目标周期为所述n个充电状态信息的反馈周期。
也就是说,供电设备410可以通过充电状态请求数据包,请求电力接收设备420按照目标周期反馈n个充电状态信息。电力接收设备420可以根据充电状态请求数据包,周期性地向供电设备410发送n个充电状态信息。
例如,供电设备410可以通过充电状态请求数据包1,请求电力接收设备420按照周期1反馈充电电压和充电电流;另外,供电设备410可以通过充电状态请求数据包2,请求电力接收设备420按照周期2反馈当前电量,其中,周期1小于周期2。也就是说,供 电设备410可以通过充电状态请求数据包1,使得电力接收设备420可以按照相对较快的频率,反馈充电电压和充电电流;并且,供电设备410可以通过充电状态请求数据包2,使得电力接收设备420可以按照相对较慢的频率,反馈当前电量。
在其他示例中,供电设备410可以通过其他无线Qi数据包指示目标周期,以请求电力接收设备420按照目标周期反馈该n个充电状态信息。
通过无线Qi数据包指示充电状态信息的反馈周期,有利于减少供电设备410向电力接收设备420发送的信令数量,还有利于灵活调整充电状态信息的反馈频率,进而有利于兼顾供电设备的耗电量和充电性能。例如,在充电状态信息的反馈周期相对合适的情况下,供电设备消耗在处理充电状态信息上的电量、提供给电力接收设备的电量可以相对合适,并且,供电设备可以获得适量的充电状态信息,以实现相对较优的充电性能。
可选的,所述充电状态请求数据包包括第一类命令符,所述第一类命令符用于指示第一类充电状态信息,所述第一类充电状态信息包括所述n个充电状态信息,n为大于1的整数。
相应地,所述电力接收设备420根据所述第一类命令符,向供电设备410发送所述n个充电状态信息。
也就是说,供电设备410可以通过第一类命令符,向电力接收设备420请求第一类充电状态信息。第一类命令符可以用于标识第一类充电状态信息。
在一个示例中,第一类充电状态信息例如可以为动态充电状态信息或静态充电状态信息。
动态充电状态信息可以指在充电过程中通常会发生变化的充电状态信息。例如,动态充电状态信息可以包括充电电压、充电电流、充电内阻、充电输入功率、当前电量、充电温度、电池健康状态等。
静态充电状态信息可以指在充电过程中通常不会发生变化的充电状态信息。例如,静态充电状态信息可以包括电池总容量、充放电循环次数、无线充电能效比、设备标识等。
应理解,多个充电状态信息的分类方式可以有不止一种。本申请实施例可以不限定充电状态信息的具体分类。
在一种可能的情况中,电力接收设备420可以仅反馈第一类充电状态信息的部分充电状态信息。例如,第一类充电状态信息可以包括第一部分充电状态信息和第二部分充电状态信息,电力接收设备420已被授权反馈第一部分充电状态信息,未被授权反馈第二部分充电状态信息,其中第一类充电状态信息可以包括所述n个充电状态信息。
可选的,供电设备410向电力接收设备420发送第二类命令符,所述第二类命令符用于指示第二类充电状态信息,所述第二类充电状态信息包括m个充电状态信息,m为大于1的整数;供电设备410从电力接收设备420接收所述m个充电状态信息,所述第一类充电状态信息与所述第二类充电状态信息之间无交集。
相应地,电力接收设备420从供电设备410接收第二类命令符,所述第二类命令符用于指示第二类充电状态信息,所述第二类充电状态信息包括m个充电状态信息,m为大于1的整数;电力接收设备420根据所述第二类命令符,向供电设备410发送所述m个充电状态信息,所述第一类充电状态信息与所述第二类充电状态信息之间无交集。
可选的,第一类充电状态信息的反馈周期可以与第二类充电状态周期的反馈周期不 同。例如,第一类充电状态信息为静态充电状态信息,第二类充电状态信息为动态充电状态信息。由于静态充电状态信息在充电过程中通常基本不发生变化,供电设备410可以在刚开始无线反向充电时,通过第一充电状态请求数据包,从电力接收设备420获取静态充电状态信息。之后,供电设备410可以向电力接收设备420发送第二充电状态请求数据包,并从电力接收设备420多次获取动态充电状态信息。
对充电状态信息分类有利于减少供电设备410的信令开销,对充电状态信息进行分类也有利于灵活调控供电设备410与电力接收设备420之间的信令传输。
图6所示的实施例通过无线Qi协议,使得在供电设备410与供电设备410之间可以交互充电状态信息。无线Qi协议与蓝牙协议、无线局域网协议不同,在供电设备410为电力接收设备420无线反向充电的过程中,供电设备410与电力接收设备420之间始终需要通过无线Qi协议进行交互,以维持正常的无线充电状态。而蓝牙协议、无线局域网协议对于供电设备410、电力接收设备420而言不是必须使用的。如果电力接收设备420不具有蓝牙功能、无线局域网功能,电力接收设备420将无法通过蓝牙协议或无线局域网协议,向供电设备410提供电力接收设备420的充电状态信息。那么,供电设备410的使用性能可以被降低。
另外,开启短距离通信功能的数量越多,电子设备的耗电量也就越大(需要时刻维持蓝牙链接或无线局域网链接),这样更加难以兼顾耗电量与无线充电性能。
并且,通过蓝牙协议、无线局域网协议等传输充电状态信息,会涉及到多个模块(例如蓝牙射频模块、存储器、处理器、无线充电芯片、电池等模块)之间的交互、配合(例如需要将蓝牙协议的数据包转换为无线Qi协议的数据包)。这可能会占用较多的数据处理资源。
下面结合图7至图19,阐述本申请实施例提供的无线充电的方法。
图7是本申请实施例提供的供电设备410的一种用户界面700。用户界面700例如可以为供电设备410的电池的设置界面。

在一个示例中,用户界面800可以包括本机停充电量的参数控件802。
如图9中的901所示,供电设备410可以获取供电设备410的当前电量。如图9中的 902所示,供电设备410可以判断供电设备的当前电量是否大于本机停充电量。在供电设备410的当前电量大于本机停充电量的情况下,供电设备410可以维持开启无线反向充电功能。如图9中的903所示,在供电设备410的当前电量小于本机停充电量,或者,供电设备410的当前电量降低至本机停充电量的情况下,供电设备410可以执行自动停充的操作,即自动关闭无线反向充电功能。
如图8所示,本机停充电量例如可以为40%。也就是说,在供电设备410的当前电量小于40%的情况下,或者,在供电设备410的当前电量降低至40%的情况下,供电设备410可以自动关闭供电设备410的无线反向充电功能。
供电设备410可以响应用户作用在该参数控件802的手势操作(例如点击等),以及后续一系列的手势操作(例如滑动、输入字符等),从而调整本机停充电量。应理解,本申请实施例可以不限定本机停充电量的具体数值。
在供电设备410自身的剩余电量不足的情况下,供电设备410可以通过关闭无线反向充电功能,来降低自身的耗电量,进而有利于提升供电设备410的待机时间。
在一个示例中,用户界面800可以包括单次耗电限量的参数控件803。
如图10中的1001所示,供电设备410可以获取供电设备的单次耗电量。
例如,在一次无线反向充电过程中,供电设备410可以记录开始无线反向充电时的起始电量,并判断供电设备410的当前电量与该起始电量的差值是否大于该单次耗电限量。该当前电量与该起始电量的差值可以反映供电设备410在该无线反向充电过程中消耗的电量,可以简称为单次耗电量。
又如,在一次无线反向充电过程中,供电设备410可以统计消耗在无线反向充电功能上的电量,并判断该电量是否大于该单次耗电限量。在一次无线反向充电过程中消耗在无线反向充电功能上的电量可以被描述为单次耗电量。
如图10中的1002所示,供电设备410可以判断供电设备410的单次耗电量是否大于该单次耗电限量。如果该单次耗电量小于该单次耗电限量,供电设备410可以维持开启无线反向充电功能。如图10中的1003所示,如果该单次耗电量大于该单次耗电限量,供电设备410可以执行自动停充的操作,即自动关闭无线反向充电功能。
如图8所示,单次耗电限量例如可以为20%。也就是说,在单次耗电限量大于20%的情况下,供电设备410可以自动关闭供电设备410的无线反向充电功能。
供电设备410可以响应用户作用在该参数控件803的手势操作(例如点击等)以及后续一系列的手势操作(例如滑动、输入字符等),从而调整单次耗电限量。应理解,本申请实施例可以不限定单次耗电限量的具体数值。
在供电设备410自身电量消耗过大的情况下,供电设备410可以通过关闭无线反向充电功能,来降低自身的耗电量,进而有利于提升供电设备410的待机时间,也有利于维持供电设备410的其他元器件的正常工作。
在一个示例中,用户界面800可以包括对端设备停充电量的参数控件804。
如图11的1101所示,供电设备410可以获取电力接收设备420的当前电量。结合图6可知,供电设备410例如可以通过充电状态请求数据包,从电力接收设备420获取电力接收设备420的当前电量。如图11的1102所示,供电设备410可以判断电力接收设备420的当前电量是否大于该对端设备停充电量。在电力接收设备420的当前电量小于对端 设备停充电量的情况下,供电设备410可以维持开启无线反向充电功能。如图11的1103所示,在供电设备410的电量大于对端设备停充电量,或者,供电设备410的电量升高至对端设备停充电量的情况下,供电设备410可以执行自动停充的操作,即自动关闭无线反向充电功能。
如图8所示,对端设备停充电量例如可以为90%。也就是说,在电力接收设备420的当前电量大于90%的情况下,或者,在电力接收设备420的当前电量升高至90%的情况下,供电设备410可以自动关闭供电设备410的无线反向充电功能。
供电设备410可以响应用户作用在该参数控件804的手势操作(例如点击等),以及后续一系列的手势操作(例如滑动、输入字符等),从而调整对端设备停充电量。应理解,本申请实施例可以不限定对端设备停充电量的具体数值。
在电力接收设备420的剩余电量相对足够的情况下,电力接收设备420的待机时间可以相对较长。通过关闭无线反向充电功能,可以降低供电设备410的耗电量,进而有利于提升供电设备410的待机时间。
在一个示例中,用户界面800可以包括历史充电设备的参数控件805。
例如,结合图6可知,供电设备410可以通过充电状态请求数据包,从电力接收设备420获取电力接收设备420的设备标识。供电设备410可以记录电力接收设备420的设备标识。可选的,供电设备410可以统计电力接收设备420的无线反向充电次数。
供电设备410可以在用户界面800上显示电力接收设备420的设备标识和无线反向充电次数。如图8所示,供电设备410曾经为蓝牙耳机A、手表B、蓝牙耳机C无线反向充电,其中蓝牙耳机A的无线反向充电次数为20次,手表B的无线反向充电次数为15次,蓝牙耳机C的无线反向充电次数为20次。可选的,供电设备410可以响应用户作用在该参数控件805的手势操作(例如点击等),显示供电设备410的无线反向充电记录(即电力接收设备420的列表)。
统计供电设备410的无线反向充电记录,有利于用户协调供电设备410的耗电方式。例如,在一周内,供电设备410曾为相对较多的电子设备提供无线反向充电功能。这有利于提示用户合理安置该电力接收设备420的充电器,以减少供电设备410的无线反向充电次数。
可选的,供电设备410可以在用户界面800上高亮显示电力接收设备420的设备标识,以便于用户查看当前电力接收设备420的设备信息。
可选的,供电设备410可以响应用户作用在该参数控件805的手势操作(例如点击等),从而将目标设备标识设置在设备黑名单中。也就是说,供电设备410可以从电力接收设备420获取电力接收设备420的设备标识,并判断该设备标识是否属于设备黑名单。如果属于,则供电设备410可以执行自动停充的操作,即自动关闭无线反向充电功能。如果不属于,则供电设备410可以维持开启无线反向充电功能,并为电力接收设备420无线反向充电。
电力接收设备420的充电性能可能会严重影响供电设备410的使用性能。通过判断电力接收设备420的设备标识是否属于设备黑名单,有利于维持供电设备410的使用性能。
图12示出了本申请实施例提供的一种无线充电的方法。图12所示的方法可以应用在图3所示的无线反向充电场景以及其他无线反向充电场景中。
如图12中的1201所示,供电设备410,例如可以通过图6所示的方法,获取电力接收设备420的电池健康状态。电池健康状态可以属于一种充电状态信息。
如图12中的1202所示,供电设备410可以根据电池健康状态,判断电力接收设备420的电池当前处于健康充电状态还是非健康充电状态。
例如,供电设备410可以将该电池健康状态对应的分数,与预设健康分数匹配,从而判断电力接收设备420的电池当前是处于健康充电状态还是非健康充电状态。
如果电池健康状态对应的分数高于预设健康分数,则供电设备410可以判断电力接收设备的电池当前处于健康充电状态。那么供电设备410可以继续为电力接收设备420无线反向充电,并继续监测电力接收设备420的电池健康状态(如图12中的1201所示)。
如果电池健康状态对应的分数低于预设健康分数,则供电设备410可以判断电力接收设备的电池当前处于非健康充电状态。那么,如图12中的1203所示,供电设备410可以主动停止为电力接收设备420无线反向充电。
图13示出了本申请实施例提供的一种无线充电的方法。图13所示的方法可以应用在图3所示的无线反向充电场景以及其他无线反向充电场景中。
如图13中的1301所示,供电设备410可以获取电力接收设备420的充电输入功率,以及供电设备410的充电输出功率。
充电输入功率可以指,供电设备410从电力接收设备420接收到的无线充电功率。充电输出功率可以指,供电设备410在无线反向充电功能上输出的功率,即供电设备410为电力接收设备420无线反向充电而输出的功率。
例如,结合图6可知,供电设备410通过无线Qi协议,通过充电状态请求数据包,向电力接收设备420请求充电输入功率。充电输入功率可以属于一种充电状态信息。
又如,结合图6可知,供电设备410通过无线Qi协议,通过充电状态请求数据包,向电力接收设备420请求充电电流和充电电压。电力接收设备420可以根据电力接收设备420的充电电流和充电电压,确定或估算电力接收设备420的充电输入功率。
如图13中的1302所示,供电设备410可以判断反向充电输出功率与充电输入功率的差值是否大于预设功率。反向充电输出功率与充电输入功率的差值可以反映无线反向充电过程中的电能损耗。
如果反向充电输出功率与充电输入功率的差值小于预设功率,可以意味着供电设备410输出的大部分功率可以用于为电力接收设备420无线反向充电。那么,供电设备410可以继续为电力接收设备420无线反向充电,并继续监测反向充电输出功率与充电输入功率的差值(如图13中的1301所示)。
如果反向充电输出功率与充电输入功率的差值大于预设功率,可以意味着无线反向充电过程中的电能损耗相对较大,可能的原因例如可以是漏电等,即可能存在安全隐患。那么,如图13中的1303所示,供电设备410可以主动停止为电力接收设备420无线反向充电。
在一些可能的场景中,电力接收设备420向供电设备410反馈功率,目的通常是指示供电设备410提供合适的无线反充功率,例如在电力接收设备420电量即将充满时,电力接收设备420可以向供电设备410发送功率指示信息,指示供电设备410降低输出功率。但是这一功率指示信息并不能反映电力接收设备420实际接收到的功率,也无法反映无线 反向充电过程中是否存在安全隐患。图13所示的方法有利于降低无线反向充电安全事故的发生概率。
图14是本申请实施例提供的一种无线充电的方法。图14所示的方法可以应用在图3所示的无线反向充电场景以及其他无线反向充电场景中。

充电温度例如可以是电力接收设备420的电池342的温度。结合图6可知,供电设备410通过无线Qi协议,通过充电状态请求数据包,向电力接收设备420请求充电温度。
如图14中的1402所示,供电设备410可以判断电力接收设备420的充电温度是否大于第一预设充电温度。如果电力接收设备420的充电温度过高,电力接收设备420的电池342可能存在充电隐患。
如果电力接收设备420的充电温度小于第一预设充电温度,可以意味着电力接收设备420的电池342当前可能处于正常充电状态,存在安全隐患的概率相对较小。那么,供电设备410可以继续为电力接收设备420无线反向充电,并继续监测电力接收设备420的充电温度(如图14中的1401所示)。
如果电力接收设备420的充电温度大于第一预设充电温度,可以意味着电力接收设备420的电池342当前可能存在安全隐患。那么,如图14中的1403所示,供电设备410可以降低供电设备的充电输出功率至第一输出功率。在一种可能的场景中,第一输出功率为零或接近零,可以等效成供电设备410自动关闭无线反向充电功能。
可选的,供电设备410可以判断在电力接收设备420的充电温度大于第二预设充电温度的情况下,供电设备410可以降低供电设备的充电输出功率至第二输出功率,第二预设充电温度大于第一预设充电温度,第二输出功率小于第一输出功率。
如果电力接收设备420的充电温度越高,电力接收设备420的电池342存在充电隐患的概率越大。本申请实施例提供的方法可以逐级减小供电设备410的充电输出功率,有利于兼顾无线反向充电功能以及无线反向充电安全。
结合上文的示例可知,在其他场景中,供电设备410可以采用逐级降低充电输出功率的方式,调整无线反向充电模式。例如,在供电设备410的当前电量低于本机停充电量的情况下,和/或,在供电设备410的单次耗电量高于单次耗电限量的情况下,和/或,在电力接收设备420的当前电量高于对端设备停充电量的情况下,供电设备410可以采用逐级降低充电输出功率的方式,调整无线反向充电模式。

2001,供电设备通过无线充电芯片,向电力接收设备发送充电状态请求数据包,所述充电状态请求数据包用于请求所述电力接收设备的n个充电状态信息,其中,所述n个充电状态信息包括以下至少一项:充电电压、充电电流、充电内阻、当前电量、充电输入功率、充电温度、电池健康指数、当前工作频率、电池总容量、充放电循环次数、无线充电能效比、设备标识,n为大于或等于1的整数。
相应地,电力接收设备通过无线充电芯片,从供电设备接收充电状态请求数据包,所述充电状态请求数据包用于请求所述电力接收设备的n个充电状态信息。
结合图6所示的示例,充电状态请求数据包例如可以包括第一前导码、第一报头、第一报文、第一校验和。
第一报头可以用于指示第一报文的数据量(、数据包类型。例如,第一报头可以包括命令符“0xa8”或“0xa9”,“0xa8”或“0xa9”所指示的数据包类型例如可以为充电状态请求数据包,“0xa8”或“0xa9”所指示的第一报文的数据量可以为a个字节。
一个实施例中,所述充电状态请求数据包包括与所述n个充电状态信息一一对应的n个命令符,所述n个命令符承载于所述充电状态请求数据包的报头或报文中。
第一报文可以包括第一命令符、第二命令符、……、第n命令符,其中第一命令符可以与第一充电状态信息对应,第二命令符可以与第二充电状态信息对应,……,第n命令符可以与第n充电状态信息对应。
第一报文的命令符例如可以由“0xXX”表示,“0xXX”可以取值0x00~0xFF。例如,0x11可以与充电前端电压对应,0x12可以与电池端电压对应,0x13可以与充电前端电流对应,0x14可以与电池端电流对应,0x15可以与充电内阻对应,0x16可以与当前电量对 应,0x17可以与无线反向充电输入功对应,0x18可以与充电温度对应,0x19可以与电池健康状态对应,0x20可以与当前工作频率对应,0x21可以与电池总容量对应,0x22可以与充放电循环次数对应,0x23可以与无线充电能效比对应,0x24可以与设备类型对应,0x25可以与设备子型号对应。应理解,本申请实施例可以不限定各个充电状态信息所对应的具体命令符。
一个实施例中,所述充电状态请求数据包包括第一类命令符,所述第一类命令符与第一类充电状态信息对应,所述第一类充电状态信息包括所述n个充电状态信息,所述第一类命令符承载于所述充电状态请求数据包的报头或报文中。
结合图6所示的示例,第一类命令符可以用于标识第一类充电状态信息。
一个实施例中,所述第一类充电状态信息为动态充电状态信息或静态充电状态信息。

一个实施例中,所述充电状态请求数据包、所述充电状态反馈数据包均为无线充电Qi协议的数据包。
无线Qi协议与蓝牙协议、无线局域网协议不同,在供电设备410为电力接收设备420无线反向充电的过程中,供电设备410与电力接收设备420之间始终需要通过无线Qi协议进行交互,以维持正常的无线充电状态。而蓝牙协议、无线局域网协议对于供电设备410、电力接收设备420而言不是必须使用的。如果电力接收设备420不具有蓝牙功能、无线局域网功能,电力接收设备420将无法通过蓝牙协议或无线局域网协议,向供电设备410提供电力接收设备420的充电状态信息。那么,供电设备410的使用性能可以被降低。
另外,开启短距离通信功能的数量越多,电子设备的耗电量也就越大(需要时刻维持蓝牙链接或无线局域网链接),这样更加难以兼顾耗电量与无线充电性能。
并且,通过蓝牙协议、无线局域网协议等传输充电状态信息,会涉及到多个模块(例如蓝牙射频模块、存储器、处理器、无线充电芯片、电池等模块)之间的交互、配合(例如需要将蓝牙协议的数据包转换为无线Qi协议的数据包)。这可能会占用较多的数据处理资源。

第二报文例如可以包括第一充电状态信息、第二充电状态信息、……、第n充电状态信息。第一充电状态信息、第二充电状态信息、……、第n充电状态信息可以分别占用第二报文的n个字节。
