具体实施方式
为了便于清楚描述本申请实施例的技术方案,在本申请的实施例中,采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。例如,第一目标功能的界面和第二目标功能的界面是为了区分不同的响应界面,并不对其先后顺序进行限定。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定,并且“第一”、“第二”等字样也并不限定一定不同。
需要说明的是,本申请中,“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其他实施例或设计方案更优选或更具优势。确切而言,使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
本申请中,“至少一个”是指一个或者多个,“多个”是指两个或两个以上。“和/或”,描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B的情况,其中A,B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达,是指的这些项中的任意组合,包括单项(个)或复数项(个)的任意组合。例如,a,b,或c中的至少一项(个),可以表示:a,b,c,a和b,a和c,b和c,或a、b和c,其中a,b,c可以是单个,也可以是多个。
本申请实施例提供的技术方案可以应用于电子设备反向充电的场景中。在长时间外出的场景中,电子设备可能因长时间无法充电而关机,这为用户造成不便。目前,大多数的电子设备使用大容量的电池进行供电,并且电子设备中可以有支持反向充电的硬件,例如,手机中的升压电路和降压电路。这样,可以将电子设备作为电源为其他电量较低的电子设备进行反向充电,为用户提供一种电子设备充电的应急方案。
一种实现中,手机A在向手机B无线充电时,手机A可以通过升压电路进行升压,并基于升压后的电压向外辐射无线充电信号,手机B接收该无线充电信号,并将接收的无线充电信号转换为输入电压为手机B的电池充电,从而实现手机A为手机B无线充电,使得手机B的电量得到及时的补充,使得手机B不会因电量低而关机,为用户造成不便的情况。
但是,上述实现中,是将手机A的电压升压一定倍数后,再由手机B降压一定倍数,手机B降压后的电压并不一定符合手机B的电池电压的情况,例如可能大于或小于手机B的电池电压,导致充电过程存在较多损耗,充电效率较低。
基于现有技术反向充电效率较低的问题,本申请实施例提供了一种反向充电系统,该反向充电系统中,第一电子设备为供电设备,第二电子设备为充电设备。在第一电子设备为第二电子设备充电的过程中,第一电子设备利用升压后的第一电压值为第二电子设备充电,第二电子设备能够将第一电子设备输出的第一电压值调整到第二电子设备的第二电池电压,并利用第二电池电压实现充电,这样,第二电子设备在充电时,可以实现电池电压与充电电压高度匹配,从而能够提升反向充电的效率。
示例性的,图1为本申请实施例提供的一种反向充电系统的应用场景示意图。如图1所示,应用场景中可以包括第一电子设备和第二电子设备。其中,第一电子设备显示的界面中可以包括时间、天气以及多个应用程序控件。本申请实施例仅以第一电子设备显示如图1的界面进行示例说明,该示例并不构成本申请实施例的限定。
如图1所示,第一电子设备当前的剩余电量为80%,第二电子设备当前的剩余电量为10%,当第一电子设备和第二电子设备之间有线连接时,第一电子设备可以为第二电子设备充电。
示例性的,本申请实施例提供的反向充电系统可以实现手机向耳机进行反向充电,或者手机向手机进行反向充电。由于耳机具有便携的特性,体积小,且电池容量通常小于手机的电池容量。因此,在耳机电量较低的情况下,可以将手机作为电源为耳机充电,能够为用户提供较大的便利。

下面以具体地实施例对本申请的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以独立实现,也可以相互结合,对于相同或相似的概念或过程可能在某些实施例中不再赘述。
示例性的,以第一电子设备和第二电子设备均为手机进行示例说明,图3为本申请实施例提供的一种反向充电系统内部架构示意图。如图3所示,第一电子设备200为供电设备,第二电子设备300为充电设备。第一电子设备200中可以包括第一协议模块201、第一片上系统202(system on chip,SOC)、第一电池203以及升压电路204。第二电子设备300中可以包括第二协议模块301、第二SOC302、第二电池303以及降压电路304。
可选的,第一协议模块201可以为第一协议芯片,第二协议模块201可以为第二协议芯片。升压电路204可以为第一SC charger或boost升压电路,降压电路304可以为第二SC charger。第一协议模块201和第二协议模块301之间可以进行通信。其中,第一协议模块201和第二协议模块301进行通信时使用的充电协议包括但不限于快速充电协议(fast fharger protocol,FCP)、超级快充协议(super charge protocol,SCP)、快充协议(quick charge,QC)、第一快速充电协议(Programmable Power Supply,PPS)、充电协议(Power Delivery,PD)、第二充电协议(adaptive fast charge,AFC)、VOOC闪充协议等。
当第一电子设备200和第二电子设备300之间有线连接时,第一电子设备200中的第一协议模块201可以通过与第二协议模块301之间的通信接收来自第二协议模块301的充电需求指令,该充电需求指令中可以携带充电功率,电压上限值,等。第二协议模块301可以通过IIC将充电需求指令发送给第一SOC202。第一SOC202基于该电压上限值控制升压电路204将第一电池电压升压到第一电压值,并利用第一电压值为第二电子设备300进行反向充电。其中,第一电压值小于电压上限值。第一电子设备200的第一电池电压随着第一电子设备200供电时长的增加而减小。
第二电子设备300中的第二协议模块301通过IIC将充电功率发送给第二SOC302。第二SOC302可以控制降压电路304将第一电压值调整到第二电子设备300的第二电池电压,并利用第二电池电压实现充电。
可以理解的是,第二电子设备300的第二电池电压随着第二电子设备300充电时长的增加而增大。其中,随着第二电子设备300充电时长的增加第二电池电压在0V至截止电压之间不断增大,例如,随着充电时长的增加,第二电子设备300的第二电池电压可以从3V升高到4.5V。当第一电子设备200为第二电子设备300充电的过程中,当第二电子设备300的第二电池电压达到截止电压,则第二电子设备300的第二电池电压不再增大。
例如,第一电子设备200通过boost升压电路2042将第一电子设备200的第一电池电压升压到9V,并向输出9V 1A给第二电子设备300,第二电子设备300通过降压电路304将9V 1A转换为5V 2A给第二电池303充电。
示例性的,第一电子设备200为第二电子设备300充电可以有以下图4-图6所示的三种可能的实现方式。下面,结合图4-图6三种可能的实现方式,对第一电子设备200为第二电子设备300进行反向充电的过程进行示例说明。图4为本申请实施例提供的一种反向充电系统的电路示意图一。图5为本申请实施例提供的一种反向充电系统的电路示意图二。图6为本申请实施例提供的一种反向充电系统的电路示意图三。
可能的实现方式中,如图4所示,第一电子设备200中的升压电路204可以为第一充电芯片,该充电芯片可以为第一SC charger2041。第一电子设备200可以包括第一协议芯片2011、第一电池203、第一SOC202、第一SC charger2041,第二电子设备300可以包括第二协议芯片3011、第二电池303、第二SOC302、降压电路304。其中,降压电路304是连续可调的降压电路。
可以理解的是,SC charger在电源转换过程中具有较高的转换效率,SC charger的电源转换效率能够达到较高的比例,例如,SC charger的电源转换效率可能达到97%。因此,使用SC charger进行反向充电,能够减少功率的损耗,提升反向充电的效率。
示例性的,当第一电子设备200和第二电子设备300之间有线连接,且确定第一电子设备200为第二电子设备300反向充电时,第一协议芯片2011通过与第二协议芯片3011之间进行通信,第一协议芯片2011可以接收来自第二协议芯片3011的电压上限值,并基于接收到的电压上限值和第一电池电压确定向第二电子设备300反向充电的电压值为X倍的第一电池电压,X为大于1的正整数。其中,X倍的第一电池电压小于电压上限值,且为了进一步提升反向充电的效率X倍的第一电池电压可以是电压上限值内允许的最大电压值。
第一SOC202基于第一协议芯片2011确定的反向充电电压值控制第一SC charger2041将第一电子设备200的第一电池电压升压到X倍的第一电池电压,并向第二电子设备300的降压电路304输出X倍的第一电池电压。例如,第一电池电压为Vabtt1,第二电池电压为Vabtt2。当第一电子设备200和第二电子设备300之间有线连接时,第一协议芯片1011确定反向充电的电池电压值可以为可以2倍的Vabtt1,第一电子设备200通过第一SC charger2041将第一电子设备200的Vabtt1升压到2倍的Vabtt1,并利用2倍的Vabtt1为第二电子设备300充电。
可以理解的是,在反向充电过程中,第一电子设备200的第一电池电压随着第一电子设备200供电时长的增加而减小,第一SC charger2041的升压比例随着第一电池电压的减小而增加。
相应的,第二电子设备300中的第二协议芯片3011可以实时向第二SOC302发送第二电池电压。第二SOC302控制降压电路304将X倍的第一电池电压降压到第二电子设备300的第二电池电压,并使用第二电池电压为第二电池303充电。
可以理解的是,在反向充电过程中,第二电子设备300的第二电池电压随着第二电子设备300充电时长的增加而增大,降压电路304不断调整其降压比例,使得降压电路304能够将X倍的第一电池电压降压到第二电池电压。
基于此,第一电子设备200通过第一SC charger2041进行升压,第二电子设备300通过降压电路304进行降压,第一SC charger2041在反向充电时的发热较小,使得第一电子设备200在充电过程中的温度上升速度缓慢,减少了功率损耗,提高了反向充电的功率,能够有效的提升反向充电的效率,提升用户体验。
可能的实现方式中,如图5所示,第一电子设备200中的升压电路204可以为boost升压电路2042,第二电子设备300中的降压电路304可以为第二充电芯片,该充电芯片可以为第二SC charger3041。第一电子设备200可以包括第一协议芯片2011、第一电池203、第一SOC202、boost升压电路2042,第二电子设备300可以包括第二协议芯片3011、第二电池303、第二SOC302、第二SC charger 3041。其中,boost升压电路2042为连续可调的升压电路。
示例性的,当第一电子设备200和第二电子设备300之间有线连接,且确定第一电子设备200为第二电子设备300反向充电时,第一协议芯片2011通过与第二协议芯片3011之间进行通信,第一协议芯片2011可以接收来自第二协议芯片3011的电压上限值和第二电子设备300的第二电池电压,并基于接收到的电压上限值、第一电池电压和第二电池电压确定向第二电子设备300反向充电的电压值为Y倍的第二电池电压,Y为大于1的正整数。其中,Y倍的第二电池电压小于电压上限值。
第一SOC202基于第一协议芯片2011确定的反向充电的电压值控制第一SC charger2041将第一电子设备200的第一电池电压升压到Y倍的第一电池电压,并向第二电子设备300的降压电路304输出Y倍的第二电池电压。例如,第一电池电压为Vabtt1,第二电池电压为Vabtt2。当第一电子设备200和第二电子设备300之间有线连接时,第一协议芯片1011确定反向充电的电池电压值可以为可以2倍的Vabtt2,第一电子设备200通过boost升压电路2042将Vabtt1升压到2倍的Vabtt2,并利用2倍的Vabtt2为第二电子设备300进行反向充电。
可以理解的是,在反向充电过程中,第一电子设备200的第一电池电压随着第一电子设备200供电时长的增加而减小,boost升压电路2042的升压比例随着第一电池电压的减小而不断变化。

可以理解的是,为了第一电子设备的正常运行,第一温度阈值与第二温度阈值之间的温度范围可以为电子设备能够稳定运行的温度范围。例如,第一温度阈值可以为20摄氏度,第二温度阈值可以为40摄氏度,即第一电子设备的温度处于在20摄氏度至40摄氏度之间时,使用图4所示的反向充电电路进行反向充电。
示例性的,若第一电子设备的温度高于第一温度阈值且低于第二温度阈值,且第一电子设备中没有SC charger,第二电子设备有SC charger时,可以通过图5所示的反向充电电路进行充电。若第一电子设备和第二电子设备均没有SC charger时,可以通过图6所示的反向充电电路进行充电。
可能的实现方式中,当第一电子设备的温度低于第一温度阈值,或第一电子设备的温度高于第二温度阈值时,可以使用图6所示的反向充电中的硬件进行反向充电,但在反向充电过程中,第一电子设备可以通过第一SOC控制boost升压电路将第一电子设备的第一电池电压升压到特定电压值,利用特定电压值为第二电子设备进行反向充电。第二电子设备通过第二SOC控制降压电路将特定电压值调整到第二电子设备的第二电池电压。其中,特定电压值为第二电子设备允许的最小充电电压值。
这样,在第一电子设备的温度较低或者较高时,第一电子设备利用第一预设值为第二电子设备反向充电,使得反向充电的功率较小,使得充电过程中的安全性较高。
在本申请实施例中,第一电子设备的温度与第二电子设备的温度和能够影响反向充电电路的选择。例如,当温度和在100℃-150℃之间时,使用功率较低的反向充电电路,即第一电子设备可以通过boost升压电路将第一电子设备的第一电池电压升压到第一预设电压值,利用第一预设电压值为第二电子设备进行反向充电。第二电子设备通过降压电路304将第一预设电压值调整到第二电子设备的第二电池电压。当温度和在50℃-100℃时,使用功率较高的反向充电电路,可以选择如图4-图6所示的充电方案中的任一种。

例如,预设值为第一电子设备的电池容量的45%,在第一电子设备的电池容量与第二电子设备的电池容量相同,且第一电子设备的第一剩余电量为20%,第二电子设备的第二剩余电量为40%,或者第一剩余电量和第二剩余电量均为20%,或者第一剩余电量和第二剩余电量均为60%时,第一电子设备使用boost升压电路将第一电池电压升压到特定电压值,第二电子设备通过降压电路将特定电压值调整到第二电子设备的第二电池电压。
这样,使得电子设备能够运行,提升了用户体验。
在本申请实施例中,在第一电子设备为第二电子设备反向充电时,第一值和第二值的差值,或者第一剩余电量和第二剩余电量的差值可能影响选择的反向充电电路。
示例的,当第一值和第二值的差值大于第一预设差值,或者第一剩余电量和第二剩余电量的差值大于第二预设差值,可以使用功率较高的反向充电电路进行反向充电,例如,使用图4-图6中的任一种;反之,则使用功率较低的反向充电电路进行反向充电,第一电子设备可以通过boost升压电路将第一电子设备的第一电池电压升压到特定电压值,利用特定电压值为第二电子设备进行反向充电。第二电子设备通过降压电路将特定电压值调整到第二电子设备的第二电池电压,并利用第二电池电压实现充电。
可能的实现方式中,在第一电子设备的第一剩余电量大于第二电子设备的第二剩余电量时,第一电子设备可以使用上述图4所示的反向充电电路进行反向充电。
在本申请实施例中,可能存在基于温度确定的反向充电电路和基于电池容量与剩余电量的乘积确定的反向充电电路不同,为了提升用户的体验,优先选择基于温度确定的升压电路和降压电路,使得反向充电的安全性较高。
可能的实现方式中,在第一电子设备的温度低于第一温度阈值或第一电子设备的温度高于第二温度阈值,且第一值大于第二值时,基于温度优先的原则,可以使用图6所示的反向充电中的硬件进行反向充电,但在反向充电过程中,第一电子设备可以通过第一SOC控制boost升压电路将第一电子设备的第一电池电压升压到特定电压值,利用特定电压值为第二电子设备进行反向充电。第二电子设备通过第二SOC控制降压电路将特定电压值调整到第二电子设备的第二电池电压,并利用第二电池电压实现充电。
在本申请实施例中,第一电子设备为第二电子设备反向充电过程中,第一电子设备和第二电子设备可以根据温度和剩余电量的变化对使用的反向充电电路进行切换,以提升用户体验。
可能的实现方式中,反向充电过程中,在第二电子设备的温度高于第二温度阈值,且第一电子设备通过充电芯片第一SC charger将第一电子设备的第一电池电压升压到X倍的第一电池电压时,第一电子设备可以切换为通过第一SOC控制boost升压电路将第一电子设备的第一电池电压升压到Y倍的第二电池电压,利用Y倍的第二电池电压为第二电子设备进行反向充电。第二电子设备可以切换为通过第二SOC控制第二SC charger将Y倍的第二电池电压调整到第二电子设备的第二电池电压,并利用第二电池电压实现充电。其中,X为大于1的正整数,Y为大于1的正整数。
示例性的,当第二电子设备中没有第二SC charger时,可以切换为使用图6所示的反向充电中的硬件进行反向充电,但在反向充电过程中,第一电子设备可以通过第一SOC控制boost升压电路将第一电子设备的第一电池电压升压到特定电压值,利用特定电压值为第二电子设备进行反向充电。第二电子设备通过第二SOC控制降压电路将特定电压值调整到第二电子设备的第二电池电压。其中,特定电压值为第二电子设备允许的最小充电电压值。这样,能够减小反向充电的功率,保护第二电子设备的电池,提升用户体验。
可以理解的是,在第二电子设备的温度降低至高于第一温度阈值且低于第二温度阈值时,第一电子设备可以再切换回之前使用的升压电路,第二电子设备可以切换回之前使用的降压电路。
