具体实施方式
相关技术中，通常有两种方法确定电池的显示电量，并将确定的显示电量进行显示，第一种是通过电量计，准确地统计电池的电量，根据统计结果，确定电池的显示电量，从而显示电池的电量。第二种是根据充放电曲线，确定在充电和放电时不同电压对应的电量。在实际应用中，通常采用第二种方法确定电池的显示电量。充电芯片中均标定有充电截止电压，在充电过程中，当充电芯片的电池引脚达到充电截止电压的时候，认定此时电池处于满电状态，由于各种原因，在标定的充电截止电压相同的情况下，不同的充电芯片对应的实际充电截止电压有0.05V的误差范围，例如，在显示无线耳机的电量的时候，由于无线耳机的制造厂商比较多，不同的制造厂商之间制造的无线耳机中配置的充电芯片不同，不同的充电芯片对应的充电截止电压不相同，可能导致一对TWS耳机左右耳机显示的电量存在差异。当出现充电芯片对应的实际充电截止电压与标定的充电截止电压不同的情况下，仍使用基于标定的充电截止电压建立的电压与电量的对应关 系来确定电池的显示电量的时候，会出现确定的电池的显示电量与电池的实际电量不同的情况，从而不能根据显示的电量准确地判断电池的用电量，导致对电池进行多次的充电行为，从而缩短电子设备的电池的使用寿命，影响用户使用。
基于此，本申请实施例提供了一种显示电量的确定方法，图1示出了本申请实施例提供的显示电量的确定方法的实现流程。如图1所示，所述方法包括：
S101：基于充电芯片的第一引脚确定第一电压；所述第一电压表征电池处于满电状态时所述第一引脚的电压；所述第一引脚为所述充电芯片的电池引脚。
这里，充电芯片是可以对电池进行充电控制的芯片，在充电芯片对电池进行充电的时候，当电池达到满电状态时的电压，在充电芯片的电池引脚采集到的电压是充电芯片的充电截止电压。第一引脚为充电芯片的电池引脚，充电芯片是通过第一引脚与电池进行连接，向电池提供充电电流和电压，通过检测充电芯片的第一引脚的电压，能够确定电池处于满电状态的第一电压。如图2所示，图2示出了一种充电芯片的示意图，图2中的BAT引脚是充电芯片的电池引脚，也就是第一引脚，在电池达到满电的状态时，BAT引脚的电压是电池处于满电状态的第一电压。例如，在电池处于满电状态时，检测到充电芯片的第一引脚的电压为4.3V，可以确定第一电压为4.3V。在实际应用中，由于制造的工艺等各种原因，可能会出现基于充电芯片的第一引脚确定的第一电压，与充电芯片标定的充电截止电压出现不同的情况，通过检测电池处于满电状态时充电芯片的第一引脚的电压，能够确定充电芯片的实际截止电压。例如，充电芯片标定的充电截止电压为4.3V，通过充电芯片的第一引脚确定的第一电压为4.25V。
在一个实施例中，所述基于充电芯片的第一引脚确定第一电压，包括：
在所述充电芯片的第二引脚表征所述电池处于完全充电状态时，检测所述第一引脚的电压，并将检测结果确定为所述第一电压；其中，
所述第二引脚表征所述电池的充电状态；
所述根据所述第一电压确定第一关系，包括：在所述第一电压与所述充电芯片标定的充电截止电压不相同的情况下，根据所述第一电压确定第一关系。
这里，充电芯片的第二引脚是漏极开路输出的充电状态指示端，能够通过第二引脚的输出电压表示电池的充电状态，当第二引脚表征电池处于完全充电状态时，表示电池已经处于充满电的特定状态，继续充电已不能使电池充电反应持续进行，在实际应用中，可以根据第二引脚输出电压的变化而确定电池是否处于完全充电状态。例如，在某些充电芯片中，电池处于完全充电状态时，充电芯片的第一引脚的电压代表着电池处于满电状态时的电压，检测充电芯片的第一引脚的电压，将检测结果确定为第一电压。在根据第一电压确定第一关系的时候，将第一电压与充电芯片标定的充电截止电压进行比较，在第一电压与充电芯片标定的充电截止电压不相同的时候，说明电池处于满电状态时，充电芯片对应的第一引脚的电压为第一电压，而不是充电芯片标定的充电截止电压，根据第一电压确定第一关系，从而能够确定电池处于满电状态时的显示电量。如图3所示，图3示出了一种充电芯片的各个引脚的连接示意图，其中，芯片的BAT引脚为第一引脚，芯片的CHG引脚为第二引脚，能够表示电池的充电状态，芯片的CHG引脚与处理器连接，处理器能够记录芯片的CHG引脚的变化情况，处理器在检测到芯片的CHG引脚表征电池处于完全充电状态，能够检测芯片的BAT引脚的输出电压，从而确定第一电压。例如，当检测芯片的BAT引脚的输出电压为4.25V，可以确定第一电压为4.25V。在实际应用中，根据充电芯片的种类、制造商等的原因，当第二引脚的输出电压为高电平时，代表着电池处于充电状态，当第二引脚的输出电压为低电平的时候表征电池处于完全充电的状态，在第二引脚由高电平转换为低电平，处于完全充电状态的时候，检测第一引脚的电压；还存在着另一种情况，当第二引脚的输出电压为低电平时，代表着电 池处于充电状态，当第二引脚的输出电压为高电平的时候，代表着电池已经处于完全充电状态，在第二引脚由低电平转换为高电平，处于完全充电状态的时候，检测第一引脚的电压。
在一个实施例中，如图4所示，所述基于充电芯片的第一引脚确定第一电压，包括：
S401：在所述电池的充电过程中，检测所述第一引脚的电压，得到检测结果。
这里，在电池的充电过程中，分为三个阶段，分别为预充阶段、恒流阶段和恒压阶段，在不同阶段中，充电芯片的第一引脚的电压会发生变化，检测第一引脚的电压，得到对应的检测结果。
S402：在所述检测结果表征所述第一引脚处于恒压状态的情况下，将所述恒压状态对应的电压确定为所述第一电压。
这里，在电池的充电过程中，最后阶段为恒压阶段，当进入到恒压阶段的时候，电池的充电电压是保持恒定的，并且，在恒压阶段的电池的充电电压通常可以看作为充电芯片的充电截止电压。在得到电池的充电过程中第一引脚的检测结果后，对检测得到的电压进行分析，当检测结果表明第一引脚处于恒压状态的情况下，说明电池处于充电过程中的恒压阶段，将恒压状态对应的电压确定为第一电压，也就是充电芯片的截止电压，其中，恒压状态可以通过检测到的结果进行确定，具体地，当连续检测到不同时刻的第一引脚的电压都相同的情况下，可以认为第一引脚处于恒压状态，例如，当检测到不同时刻的第一引脚的电压分别为3.5V，4.0V，4.25V，4.25V，4.25V，由于在检测结果中多次出现4.25V的电压值，并且在一段时间内保持不变，可以确定第一引脚已经处于恒压状态，且4.25V为第一电压。在实际应用中，可以在充电的过程中，设置检测第一引脚的时间周期，例如每30s检测第一引脚的电压，当出现不同时刻的第一引脚的电压相同的时候，可以在一段时间内观察第一引脚的电压是否保持不变，例如，可以设置观察2min内的第一引脚的电压。通过在电池处于充电过程中的恒压阶段，确定电池芯片的第一电压，从而不用在电池完成充电的时候才能确定电池芯片的第一电压，能够快速地确定电池芯片的第一电压。
S102：根据所述第一电压确定第一关系；所述第一关系表征所述第一引脚的电压与所述电池的电量的对应关系。
这里，在确定第一电压之后，根据第一电压确定第一关系，第一关系可以是以第一关系表的形式进行表示，通过第一关系表记录第一引脚的电压与电池的电量的对应关系，也可以是以计算公式的形式进行表示，通过第一关系式计算第一引脚的电压对应的电池的电量。例如，当确定的第一电压为4.25V的时候，由于第一电压对应的是电池处于满电状态时的电压，在建立关系表的时候，可以确定4.25V的电压对应的电池的电量为100％，并根据第一电压，确定电池在不同电量对应的电压，从而建立第一关系表。
在一个实施例中，如图5所示，所述根据所述第一电压确定第一关系时，所述方法包括：
S501：确定第一差值；所述第一差值表征所述第一电压与第二电压之间的差值；所述第二电压表征所述电池维持电子设备正常工作时所需的最小电量对应的所述第一引脚的电压。
这里，电子设备可以是指通过电池供电的设备，其中电池可以是可充电电池。例如无线耳机、音箱、手机、平板电脑、笔记本电脑等设备。在确定第一电压之后，确定第一电压与第二电压之间的差值，得到第一差值，第二电压是指维持电子设备正常工作时所需的最小电量对应的所述第一引脚的电压，例如，第二电压可以是电池的显示电量为0％的时候，电池芯片的第一引脚的电压。当电子设备的电池的剩余电量达到维持电子设备正常工作所需的最小电量时，设置电子设备停止工作，且电子设备停止工作时刻显 示的电量为0％。为了避免因电池电量反复耗尽而可能对电池使用寿命带来的负面影响，在实际应用中，可以对维持电子设备正常工作所需的最小电量进行设置，以使得电子设备显示的电量达到0％的时候，电子设备的电池还存余一些电量。可示的，当电池处于满电状态时，电源芯片的第一引脚对应的电压为第一电压，当电池的显示电量为0％的时候，电源芯片的第一引脚对应的电压为第二电压，例如，当电池处于满电状态时，对应的第一电压为4.25V，电池的显示电量为0％时，对应的第二电压为3.3V，可以确定第一差值为0.95V。
S502：确定第二差值；所述第二差值表征所述第一引脚的电压与所述第二电压的差值。
这里，第一引脚的电压表征电池对应的实测电压，确定第一引脚的电压与第二电压的差值为第二差值。第一电压为电池处于满电状态时第一引脚的电压，第二电压为电池的电量耗尽时第一引脚的电压，第一电压与第二电压确定了第一关系中的电压取值范围，因此，电池在不同电量下对应的第一引脚的电压都落入到第一电压与第二电压确定的电压范围内。例如，第一电压为4.25V，第二电压为3.3V，第一电压和第二电压确定了第一关系中的电压取值范围为[3.3V，4.25V]，可以确定第一引脚的电压为[3.3V，4.25V]范围内的电压值，例如第一引脚的电压为3.4V，那么可以确定第二电压3.3V和第一引脚的电压3.4V对应的第二差值为0.1V。
S503：根据第一差值与所述第二差值的比例关系，确定所述第一关系中所述第一引脚的电压与电量的对应关系。
这里，根据第一差值与第二差值的比例关系，能够确定在第一电压和第二电压确定的电压范围内的第一引脚的电压对应的电池的电量，从而确定第一关系。在实际应用中，第一关系可以是第一关系表，也可以是第一关系式，只要能表征第一引脚的电压与显示电量的关系即可，例如获取显示电量的第一关系式可以表示为：
Figure PCTCN2021096046-appb-000001
其中，P表示第一引脚的电压对应的电量，通过百分数的形式表示电量的大小，D 1表示第一差值，D 2表示第二差值，通过电量的算法表达式，能够确定第一引脚的电压对应的电量，从而能够确定第一关系中电量与电压的对应关系。例如，第一电压为4.25V，第二电压为3.3V，第一引脚的电压为3.4V，可以确定第一差值为0.95V，第二差值为0.1V，根据
Figure PCTCN2021096046-appb-000002
能够确定第一引脚的电压为3.4V时，对应的电量为11％。当然，也可以根据上述关系式，通过检测不同的第一引脚的电压，能够确定不同第一引脚的电压对应的电量，生成第一关系表，表1为根据第一差值与第二差值的比例关系建立的第一关系表。

在一个实施例中，如图6所示，所述根据所述第一电压确定第一关系，包括：
S601：确定设定的第二关系；所述第二关系中第一电量对应的电压为第三电压；所述第一电量表征所述电池的满电电量；所述第三电压表征所述充电芯片标定的充电截止电压。
这里，确定设定的第二关系，第二关系是基于第三电压确定的电压与电量的对应关系，第三电压代表充电芯片标定的截止电压，在实际应用中，存在着不同规格的充电芯片，充电芯片的不同主要包括充电芯片标定的充电截止电压不同，在选择充电芯片的时候，通常根据电池的种类和电池的参数，选择合适的标定的充电截止电压的充电芯片，从而能够更好地管理电池。在第二关系中，第一电量对应的电压为第三电压，第一电量是指电池的满电电量，也就是说，电池电量为100％时对应的电压为第三电压。在实际应用中，电子设备可以在出厂前已经配置了基于标定的充电截止电压确定的电压与电量的对应关系，即第二关系，从而根据第二关系中电压与电量的对应关系，显示电池的电量。第二关系可以是第二关系表的形式，也可以是第二关系式的形式等，例如，以第二关系表为例，当充电芯片标定的截止电压为4.3V，表2示出了设定的第二关系表。在表2中，电池的满电电量对应的电压为第三电压。

S602：基于所述第二关系，根据所述第一电压确定所述第一关系。
这里，在确定设定的第二关系之后，基于第二关系，根据第一电压，调整第二关系中的电压与电量的对应关系，从而在第二关系的基础上确定第一关系。在实际应用中，可以在第一电压与第二电压不相同的情况下，基于第二关系，根据第一电压确定第一关系，即充电芯片实际的充电截止电压与充电芯片标定的充电截止电压不相同的情况下，根据充电芯片实际的充电截止电压，确定电压与电量的对应关系，生成第一关系，从而能够确定显示电池的显示电量。
在一个实施例中，所述基于所述第二关系，根据所述第一电压确定所述第一关系，包括：
将所述第二关系中第一电量对应的电压更新为所述第一电压，得到所述第一关系。
这里，在基于第二关系，根据第一电压确定第一关系的时候，将第二关系中第一电量对应的电压修改为第一电压，从而能够根据充电芯片实际的充电截止电压，动态调整电压与电池满电电量之间的对应关系，在显示电池的电量的时候，能够准确显示出电池的电量处于满电的状态。例如，以第二关系为第二关系表的形式为例，当第一电压为4.25V，第三电压为4.3V的时候，如果没有调整电压与电量的关系，在确定电池的显示电量时，在设定的第二关系表中确定电池的电量与电压之间的对应关系，由于第一电压为4.25V，代表着当充电芯片的第一引脚的电压为4.25V的时候，电池处于满电状态，电池的电量为100％，在设定的第二关系表中可以确定电压为4.25V时，对应的电池的电量为95％，即确定电池的显示电量为95％，导致显示的电量为95％，并不能准确地显示电池的电量，并且，由于充电芯片的充电截止电压为4.25V，在电压达到4.25V的时候停止对电池进行充电，从而充电芯片的第一引脚的电压是不能达到4.3V的，根据设定的第二关系表确定电池的显示电量的时候，是不会出现显示电池的电量为100％的情况，会让用户误以为电池出现问题。将设定的第二关系表中第一电量对应的电压修改为第一电压，使电量100％时对应的电压为4.25V，在这种情况下，能够根据确定的电池的显示电量，准确地显示电池的满电电量。在实际应用中，可以先确定第一电压与第三电压是否相同，在第一电压与第三电压不相同的情况下，将第二关系中第一电量对应的电压更新为第一电压，得到第一关系，如果第一电压与第三电压相同时，不需要更新第二关系中第一电量对应的电压，可直接根据第二关系确定电池的显示电量。
在一个实施例中，如图7所示，所述基于所述第二关系，根据所述第一电压确定所述第一关系，包括：
S701：确定第三差值；所述第三差值表征所述第一电压与所述第三电压之间的差值。
这里，根据第一电压与第三电压，确定第三差值。当第一电压与第三电压相同时，第三差值为零。当第一电压与第三电压不相同时，可以确定第三差值为大于零的数值，例如，当第一电压为4.25V，第三电压为4.3V，可以确定第三差值为0.05V。
S702：根据所述第三差值，更新所述第二关系内所有电量中的全部或部分电量对应的电压，得到所述第一关系；其中，
所述部分电量包括第一电量。
这里，以第二关系表的形式为例，在确定第三差值之后，根据第三差值，将第二关系表内每个电量对应的电压进行调整，将调整后的电压与电量的对应关系确定为第一关系表。在实际应用中，将第二关系表内每个电量对应的电压进行调整主要是将第二关系表内每个电量对应的电压下调，下调的幅度为第三差值。例如，在设定的第二关系表内电量为0％对应的电压为3.3V，根据第三差值将3.3V下调，更新后的电量为0％对应的电压为3.25V，将设定的第二关系表中每个电量对应的电压进行调整之后，能够得到第一关系表。表3为根据第三差值，基于设定的第二关系表生成的第一关系表。在表3中，在第一关系表中每个电量对应的电压是将设定的第二关系表中的每个电量对应的电压下调第三差值得到的。除了对第二关系表内所有电量中每个电量对应的电压进行更新之外，还可以将第二关系表内所有电量中的部分电量对应的电压进行更新，得到第一关系表，其中，在对部分电量对应的电压进行更新时，至少更新第一电量对应的电压，从而保证能够显示电池电量处于满电的状态，例如，只更新第二关系表中满电电量(电量为100％)对应的电压以及电子设备不能维持正常工作的电量对应的电压。在实际应用中，当第一电压与第三电压相同时，第三差值为零，由于根据第三差值进行调整后每个电量 对应的电压与第二关系表相同，在此基础上，不需要对第二关系表进行调整生成第一关系表，可直接根据第二关系表确定电池的显示电量，从而能够节省处理时间与终端的功耗。当然，第二关系也可以以第二关系式的形式存在，从而可以在测得第一引脚的电压后根据第三差值计算出对应的显示电量，无需查表获得，计算原理与第二关系表的方式相同，在此不再赘述。

S103：基于所述第一关系，根据所述第一引脚的电压确定电池的显示电量。
这里，通过第一关系，根据第一引脚的电压确定电池的显示电量。第一关系中准确地记录了充电芯片的第一引脚的电压与电池的电量之间的对应关系，当确定了充电芯片的第一引脚的电压之后，通过第一关系，确定充电芯片的第一引脚的电压对应的电量，并将充电芯片的第一引脚的电压对应的电量确定为电池的显示电量，电子设备能够在相应的界面上将显示电量进行显示。例如，以第一关系通过第一关系表进行表征为例，当检测到充电芯片的第一引脚的电压为4.25V，在第一关系表中搜索电压值为4.25V对应的电量，在第一关系表中确定4.25V的电压对应的电量为100％时，可以确定电池的显示电量为100％，根据电池的显示电量，显示当前的电池电量为100％。在实际应用中，可以确定真无线(TWS，True wireless Stereo)耳机的电量、无线鼠标的电量等其他无线设备的电池的显示电量。例如，在实际应用中，一双TWS耳机配备了左耳使用的TWS耳机和右耳使用的TWS耳机，在移动终端(例如手机、平板电脑、智能手表等可与耳机连接的设备)上显示每只TWS耳机的电池电量的时候，TWS耳机根据第一关系表确定TWS耳机的充电芯片的第一引脚电压对应的电量，即TWS耳机的显示电量，通过蓝牙等通信方式，将对应的电量发送到移动终端(一般是TWS耳机中的主耳机与移动终端进行通信，从耳机通过主耳机上传数据给移动终端)，移动终端接收相关信息后，在移动终端的电池电量显示界面上，实时显示TWS耳机的电池电量。TWS耳机的电池电量也可以在充电盒上显示，TWS耳机根据第一关系表，确定TWS耳机的充电芯片的第一引脚的电压对应的电量，将电量通过蓝牙等无线通信方式或触点、接口等有线方式发送到充电盒，充电盒接收到相关数据后，显示TWS耳机电池电量。
本申请实施例中，基于充电芯片的第一引脚确定第一电压，第一电压表征电池处于满电状态时第一引脚的电压，第一引脚为充电芯片的电池引脚，根据第一电压确定第一 关系，第一关系表征第一引脚的电压与电池的电量的对应关系，基于所述第一关系，根据所述第一引脚的电压确定电池的显示电量，能够根据电池处于满电状态时，充电芯片的第一引脚的电压确定电压与电池的对应关系，从而能够确定电池的显示电量，准确地显示电池的电量，能够根据显示的电池的电量准确判断电池的电量的使用情况，应用在TWS耳机上可以减少当左右耳耳机采用了标定充电截止电压(即第三电压)不一样的充电IC时，可能给用户造成的以下影响：1、左右耳机充满后的电量不一样，例如，极限条件下一只耳机充满了，但是另外一只耳机只充到95％情况；2、由于耳机充满时的电量不一样，两只耳机同时使用，显示左右耳剩余的电量也不一样，这样会给用户造成一只耳机耗电快，一只耳机耗电慢的情况，用户可能会以为耳机坏了；3、由于显示电量不准确可能导致用户更频繁的充电，从而影响电池寿命。因此，通过本实施例可以提高用户的体验。
上述实施例示出了电子设备在出厂后，在使用过程中对电池电量显示进行校准，本申请实施例还提供了在出厂前对完成对电池电量显示进行校正的设置方法。需要说明的是，上述出厂后和下述出厂前的方案可以一起应用，即在出厂时按照以下出厂前的方案，保障用户开始使用时电池电量显示的准确性；出厂后实际使用中，按照上述出厂后的方案，保障每次充放电过程中电池电量显示的准确性。
在一个实施例中，如图8所示，所述显示电量的确定包括：
S801：在充电芯片的充电功能使能的情况下，对所述充电芯片上电，并采集所述充电芯片的第一引脚外部的第一电压；在采集所述第一电压时，所述第一引脚外部开路；所述第一引脚为所述充电芯片的电池引脚。
这里，充电芯片的充电功能通过充电芯片的使能端控制，使充电芯片可以关闭充电功能，也可以打开充电功能。在充电芯片的充电功能使能的情况下，给予充电芯片外部电源，在第一引脚外部开路的状态下，采集充电芯片的第一引脚的电压，由于第一引脚处于开路的状态，此时采集到的第一引脚的电压可以视作是充电芯片的充电截止电压，其中，第一引脚为充电芯片的电池引脚，与电池端连接的引脚。以图3的充电芯片的示意图为例，充电芯片的EN引脚，是控制充电芯片的充电功能，当EN引脚输入高电平的时候，充电芯片的充电功能关闭，当EN引脚输入低电平的时候，充电芯片的充电功能使能。在测量充电芯片的充电截止电压的时候，需要向充电芯片的EN引脚输入低电平，向充电芯片的VIN引脚接入外部电源，并使充电芯片的BAT引脚处于开路状态，对充电芯片上电之后，采集充电芯片的BAT引脚的电压，将采集到的充电芯片的BAT引脚的电压确定为第一电压，从而能够快速得到第一电压。在实际应用中，在对充电芯片进行装配印刷电路板(PCBA，printed circuit board assembly)端测试的时候，可以通过上述方式采集到充电芯片的BAT引脚在开路状态下的电压。
S802：根据所述第一电压确定第一关系；所述第一关系表征所述第一引脚的电压与所述电池的电量的对应关系，以使电子设备根据所述第一引脚的电压确定电池的显示电量。
这里，在确定了第一电压之后，根据第一电压确定第一关系，第一关系表征第一引脚的电压与电池的电量之间的对应关系，第一关系可以是以第一关系表的形式，也可以是第一关系式的形式，通过第一关系，能够使电子设备可以根据第一引脚的电压确定电池的显示电量。具体地，将第一电压与电池的电量为100％生成对应关系，在确定第一电压与电量为100％的对应关系，可以确定其他电量对应的第一引脚的电压。以第一关系表为例，在实际应用中，为了避免误差，通常确定电量相隔10％时所对应的第一引脚的电压，例如，确定电量为100％对应的第一引脚的电压之后，确定电量为90％对应的第一引脚的电压，从而能够确定第一关系表。对第一关系表进行存储，使电子设备能够 基于存储的第一关系表，根据第一引脚的电压，确定电池的显示电量。
在一个实施例中，如图9所示，所述根据所述第一电压值确定第一关系时，所述方法包括：
S901：确定第一差值；所述第一差值表征所述第一电压与第二电压之间的差值；所述第二电压表征所述电池维持电子设备正常工作时所需的最小电量对应的所述第一引脚的电压。
这里，确定第一电压与第二电压之间的第一差值，第二电压是指电池维持电子设备正常工作时所需的最小电量对应的所述第一引脚的电压，第二电压可以是电池显示的电量为0％的时候，电池芯片的第一引脚的电压。当电子设备的电池的剩余电量达到维持电子设备正常工作所需的最小电量时，设置电子设备停止工作，且电子设备停止工作时刻显示的电量为0％。为了避免因电池电量反复耗尽而可能对电池使用寿命带来的负面影响，在实际应用中，可以对维持电子设备正常工作所需的最小电量进行设置，以使得电子设备的显示电量达到0％的时候，电子设备的电池还存余一些电量。可示的，当电池处于满电状态时，电源芯片的第一引脚对应的电压为第一电压，当电池的显示电量为0％的时候，电源芯片的第一引脚对应的电压为第二电压，例如，当电池处于满电状态时，第一电压为4.25V，电源的显示电量为0％时，第二电压为3.3V，那么第一差值为0.95V。
S902：确定第二差值；所述第二差值表征所述第一引脚的电压与所述第二电压的差值。
这里，确定第二差值，第二差值通过第一引脚的电压与第二电压的差值确定，第一引脚的电压表征电池对应的实测电压。在确定了第一电压与第二电压之后，由第一电压与第二电压确定的电压范围是第一关系中不同电量对应的电压的取值范围，第一引脚的电压均落入由第一电压与第二电压确定的电压范围内。例如，当第一电压为4.25V，第二电压为3.3V，第一引脚的电压可以为[3.3，4.25]范围内的一个数值，例如，选择3.6V作为第一引脚的电压，可以确定第二差值为0.3。
S903：根据第一差值与所述第二差值的比例关系，确定所述第一关系中第一引脚的电压与电量的对应关系。
这里，在确定第一差值与第二差值之后，根据第一差值与第二差值的比例关系，能够确定第一引脚的电压对应的电量，从而能够确定第一关系。以第一关系式为例，第一差值与第二差值的比例关系为

其中，P表示第一引脚的电压对应的电量，通过百分数的形式表示电量的大小，D 1表示第一差值，D 2表示第二差值，通过第一差值与第二差值的比例关系，能够确定第一引脚的电压对应的电量。例如，第一电压为4.25V，第二电压为3.3V，第一引脚的电压为3.6V，第一差值为0.95，第二差值0.3，通过第一差值与第二差值的比例关系

能够得到第一引脚的电压为3.6V对应的电量为32％，也就是说当检测到充电芯片的第一引脚的电压为3.6V的时候，显示的电池电量为32％。当然，也可以通过第一关系表的形式表示第一关系，例如根据上述公式，通过确定在第一电压与第二电压确定的电压范围内的第一引脚的电压对应的电量，能够确定第一关系表，从而可以通过查表的方式确定第一引脚的电压所对应的显示电量。
在一个实施例中，如图10所示，所述根据所述第一电压确定第一关系，包括：
S1001：确定设定的第二关系；所述第二关系中第一电量对应的电压为第三电压；所述第一电量表征所述电池的满电电量；所述第三电压表征所述充电芯片标定的充电截止电压。
这里，确定设定的第二关系，第二关系是基于第三电压确定的电压与电量的对应关 系，第三电压代表充电芯片标定的截止电压，可以通过充电芯片的规格确定第三电压。在第二关系中，第一电量对应的电压为第三电压，第一电量是指电池的满电电量，也就是说，电池电量为100％时对应的电压为第三电压。在实际应用中，电子设备可能在出厂前已经配置了基于标定的充电截止电压确定的电压与电量的对应关系，即第二关系，从而根据第二关系中电压与电量的对应关系，确定电池的显示电量。第二关系可以是第二关系表的形式，也可以是第二关系式的形式。
S1002：基于所述第二关系，根据所述第一电压确定所述第一关系。
这里，在确定设定的第二关系之后，基于第二关系，根据第一电压，调整第二关系中的电压与电量的对应关系，从而在第二关系的基础上确定第一关系。在实际应用中，可以在第一电压与第二电压不相同的情况下，基于第二关系，根据第一电压确定第一关系，即充电芯片实际的充电截止电压与充电芯片标定的充电截止电压不相同的情况下，根据充电芯片实际的充电截止电压，确定电压与电量的对应关系，生成第一关系，从而能够确定电池的显示电量，更准确地显示电池的电量。
在一个实施例中，所述基于所述第二关系，根据所述第一电压确定所述第一关系，包括：
将所述第二关系中第一电量对应的电压更新为所述第一电压，得到所述第一关系。
这里，以关系表为例，在基于第二关系表，根据第一电压确定第一关系表的时候，将第二关系表中第一电量对应的电压修改为第一电压，从而能够根据充电芯片实际的充电截止电压，动态调整电压与电池满电电量之间的对应关系，在显示电池的电量的时候，能够准确显示出电池的电量处于满电的状态。对于关系式的情况，可以先确定第二关系式，将第一引脚的第一电压对应第一电量(满电电量)，第一引脚的其他电压仍然采用第二关系式确定对应的显示电量即可。在实际应用中，可以先确定第一电压与第三电压是否相同，在第一电压与第三电压不相同的情况下，将第二关系中第一电量对应的电压更新为第一电压，得到第一关系，如果第一电压与第三电压相同时，不需要更新第二关系中第一电量对应的电压，可直接根据第二关系确定电池的显示电量。在其他实施例中，也可以先判断第一电压与第三电压是否相同，相同就不用更新对应的关系表，不同才需要根据对应的实施例提供的方案进行更新，得到第一关系表。
在一个实施例中，如图11所示，所述基于所述第二关系，根据所述第一电压确定所述第一关系，包括：
S1101：确定第三差值；所述第三差值表征所述第一电压与所述第三电压之间的差值。
这里，根据第一电压与第三电压，确定第三差值，第三差值是指充电芯片实际的截止电压与充电芯片标定的截止电压之间的差值。当第一电压与第三电压相同时，第三差值为零。当第一电压与第三电压不相同时，例如，当第一电压为4.25V，第三电压为4.3V，可以确定第三差值为0.05V。
S1102：根据所述第三差值，更新所述第二关系内所有电量中的全部或部分电量对应的电压，得到所述第一关系；其中，
所述部分电量包括第一电量。
这里，以关系表为例，在确定第三差值之后，根据第三差值，将第二关系表内每个电量对应的电压进行调整，将调整后的电压与电量的对应关系确定为第一关系表。在实际应用中，将第二关系表内每个电量对应的电压进行调整主要是将第二关系表内每个电量对应的电压下调，下调的幅度为第三差值。例如，在设定的第二关系表内电量为0％对应的电压为3.3V，根据第三差值将3.3V下调，更新后的电量为0％对应的电压为3.25V，将设定的第二关系表中每个电量对应的电压进行调整之后，能够得到第一关系表。在实 际应用中，当第一电压与第三电压相同时，第三差值为零，可直接根据第二关系表显示电池的电量，从而能够节省处理时间与终端的功耗。除了对第二关系表内所有电量中每个电量对应的电压进行更新之外，还可以将第二关系表内所有电量中的部分电量对应的电压进行更新，得到第一关系表，其中，在对部分电量对应的电压进行更新时，至少更新第一电量对应的电压，从而保证能够确定电池的显示电量为100％，显示电池电量处于满电的状态，例如，只更新第二关系表中满电电量(电量为100％)对应的电压以及电子设备不能维持正常工作的电量对应的电压。此外，另一种方案中，第二关系以第二关系式的形式存在，根据第二关系式得到第一关系式，无需生成相应的关系表，而是生成相应的关系式，在检测第一引脚的电压后调用相应的关系式计算出对应的显示电量。
本申请还提供了一个应用实施例。如图12所示，图12示出了真无线(TWS，True wireless Stereo)耳机以及耳机盒的示意图。在实际应用中，一对TWS耳机中，每只TWS耳机的底部均设置有两个金属引脚，用于耳机盒给TWS耳机进行充电或者通讯使用，金属引脚的位置可以设置于TWS耳机的耳机杆的底部，也可以设置于TWS耳机的耳塞的下方，图12示出了位于TWS耳机的耳塞下方的金属引脚。与TWS耳机配套的充电盒可以收纳TWS耳机，充电盒里针对每只TWS耳机设置了两个充电铜柱，图12示出了在充电盒的底部含有两个充电铜柱，与TWS耳机的耳机杆底部的两个金属引脚接触之后，可以通过无线充电的方式为TWS耳机进行充电。在将TWS耳机放置在耳机盒内进行充电的时候，能够在TWS耳机处于满电的状态时，检测对应的充电芯片的第一引脚的输出电压，得到第一电压，根据第一电压确定实际的电量与电压的第一关系，通过检测充电芯片的第一引脚的电压，在第一关系中确定第一引脚的电压对应的电量，实时地显示TWS耳机的电量。TWS耳机的电量可以显示在充电盒上，也可以在与TWS耳机连接的设备上显示TWS耳机的电量。例如，当TWS耳机的电量耗尽的情况下，放进充电盒进行充电，此时，充电盒可以显示TWS耳机在充电过程中的电量。在实际应用中，除了可以显示TWS耳机的电量，还可以显示其他电子设备的电量，例如，显示蓝牙手表的电量。应用在TWS耳机上可以减少当左右耳耳机采用了标定充电截止电压(即第三电压)不一样的充电IC时，可能给用户造成的以下影响：1、左右耳机充满后的电量不一样，例如，极限条件下一只耳机充满了，但是另外一只耳机只充到95％情况；2、由于耳机充满时的电量不一样，两只耳机同时使用，显示左右耳剩余的电量也不一样，这样会给用户造成一只耳机耗电快，一只耳机耗电慢的情况，用户可能会以为耳机坏了；3、由于显示电量不准确可能导致用户更频繁的充电，从而影响电池寿命。因此，通过本实施例可以提高用户的体验。
