具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
在本申请中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他 性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
本申请提供一种电池电量的检测方法，以解决现有技术在获取便携式电子产品的剩余电量时，需要在其电池端集成电量计芯片而带来的成本过高的问题。
请参见图1，该电池电量的检测方法，主要包括以下步骤：
S101、分别获取电池的环境温度和电池所属终端的当前工作状态。
其中，对于获取电池的环境温度的方式不做具体限定，如果电池所属终端中设置有环境温度的传感器，则可以直接获取环境温度；而如果电池所属终端中仅设置有检测工作器件温度的传感器，则可以通过对这一传感器的温度采集结果进行修正，得到环境温度。
实际应用中，电池所属终端中的温度采集结果可以是设置于所属终端内任一温度传感器对相应工作器件温度采集得到的结果，本申请对温度采集结果获得的方式不作具体限定，无论采用何种方式获得，均属于本申请的保护范围。
在实际应用中，若电池为对讲机内的电池，则该电池的所属终端为对讲机；该对讲机内一般为其射频器件设置有相应的温度传感器，所以可以采用该射频器件的温度采集结果进行修正，以得到环境温度。若电池为其他移动终端中的电池，则该电池的所属终端为相应的移动终端，其内部的关键工作器件也一般设置有温度传感器，均可以实现对于环境温度的获取。
需要说明的是，移动终端可以是现有技术中任何设有电池的便携式电子产品，本申请对电池的移动终端的类型不作具体限定，均属于本申请的保护范围。
在电池所属终端的状态发生改变时，所属终端或者所属终端中的软件会进行相应的纪录，因此能够直接通过所属终端或者所属终端中的软件，实时获取得到该电池所属终端的当前工作状态。
当电池的所属终端为对讲机时，按照电池所属终端的工作状态进行划分， 该电池所属终端的当前工作状态一般包括：发射状态、接收状态及待机状态。
S102、从预存的不同温度状态组合下的电池充放电曲线中，确定与环境温度和终端的当前工作状态存在对应关系的电池充放电曲线，作为目标曲线。
发明人经研究发现，环境温度和电池所带负载的状态，均对电池充放电的特性有影响，也即，不同环境温度和电池所带负载的状态下，应该有不同的电池充放电曲线；而电池所带负载的状态又与电池当前工作状态密切相关，所以，在实际应用中，可以通过模拟实验或者实际测量的方式，得到电池在不同环境温度和不同电池状态下的多种充放电曲线。然后将其预置于执行该检测方法的设备中。
因此，预存的不同温度状态组合下的电池充放电曲线为：电池在多个不同环境温度和多个不同电池状态下的多种电池充放电曲线；视其实际应用环境，可以对其全部可能工作范围内的多种环境温度和电池状态分别进行测量，以增大检测范围；并且，还可以根据实际应用需要，来对环境温度和电池状态的取值颗粒进行设置，以在满足检测需要的情况下，提高检测结果的准确性。
S103、获取电池的当前电压。
现有的各种带电池的便携式电子产品中，一般均设置有相应的电池电压检测设备；所以，可以通过这些原有的设备，获取得到电池的当前电压。
当然，还可以通过现有的其他方式，获取得到电池的当前电压，本申请对获取电池当前电压的方式不作具体限定，均属于本申请的保护范围。
S104、结合与目标曲线对应的电压电量关系表，确定当前电压对应的电池电量值。
该电压电量关系表可以在预置有充放电曲线之后，将全部充放电曲线一一对应转换成相应的电压电量关系表，以备后续调用。所以，当确定环境温度、终端的当前工作状态及当前电压之后，即可通过相互相应的电压电量关系表确定电池电量值。
在本实施例提供的检测方法中，首先获取电池的环境温度和电池所属终端的当前工作状态；进而从预存的不同温度状态组合下的电池充放电曲线中，确定与环境温度和终端的当前工作状态存在对应关系的电池充放电曲线，作为目标曲线；然后以获取得到的电池当前电压，结合与目标曲线对应的电压电量关 系表，确定出当前电压所对应的电池电量值；由于环境温度、当前工作状态及当前电压，均能够通过电池所属终端中的原有设备采集得到，因此本方法通过原有设备的采集信息，结合预存的电池充放电曲线即可确定出剩余电量，而无需在电池端集成电量计芯片，相较于现有技术能够降低制造成本；并且，还能避免使用电量计芯片而带来的电池功率损耗，延长电池的续航时间。
可选地，在实际应用中，若是温度采集结果为电池所属终端中预设工作器件的温度采集值，则对电池所属终端中的温度采集结果进行修正，得到环境温度的具体过程如图2所示，包括：
S201、根据预设的温度补偿方程，确定温度采集值对应的温度补偿值。
其中，若终端为对讲机、预设的工作器件为射频器件，则在射频器件处于发射状态时，预设的温度补偿方程为：
Figure PCTCN2020113689-appb-000003
其中，x表示发射时长，单位为0.1s。
在射频器件处于接收状态时，预设的温度补偿方程为：
Figure PCTCN2020113689-appb-000004
其中，x表示结束发射时长，单位为0.1s。
S202、以温度采集值减去温度补偿值的差，作为环境温度。
下面以一具体实例，对获得预设的温度补偿方程的过程进行详细说明：
假设预设工作器件为电池所属终端中的射频器件，则根据实验观察可知，在射频器件处于工作状态时，射频器件的温度呈逐渐上升的趋势变化；而在射频器件停止工作时，射频器件的温度呈逐渐下降至环境温度的趋势变化。也即，当终端处于发射状态时，温度呈一定的上升趋势，在发射结束后，温度呈一定 的下降趋势。
本申请利用电池所属终端中射频器件的温度与环境温度之间的变化特点，对射频器件的温度进行一定的补偿，以此得到电池的环境温度。
具体的，假设以电池所属终端的室温作为电池的环境温度。可以分别获取电池所属终端在室温为22℃、发射时间少于20s的温度变化曲线(图3)、电池所属终端在室温为22℃、发射时间大于等于20s的温度变化曲线(图4)、电池所属终端在室温为0℃、发射时间小于20s的温度变化曲线(图5)、电池所属终端在室温为0℃、发射时间大于等于20s的温度变化曲线(图6)、电池所属终端在室温为-10℃、发射时间小于20s的温度变化曲线(图7)、电池所属终端在室温为-10℃、发射时间大于等于20s的温度变化曲线(图8)。然后，将图3至图8所得的温度变化曲线进行拟合，就能得到电池所属终端在发射状态下的预设温度补偿方程(1)。
在实际应用中，若是射频器件的发射时间小于20s，则采用方程(1)中的第一个公式进行计算。而射频器件的发射时间大于等于20s，则采用方程(1)中的第二个公式进行计算。
同理，也可以获取电池所属终端在室温为0℃、结束发射时间少于20S的温度变化曲线(图9)、电池所属终端在室温为0℃、结束发射时间大于等于20S的温度变化曲线(图10)。然后，将图9和图10所得的温度变化曲线进行拟合，以得到电池所属终端在结束发射状态下的温度补偿方程(2)。
在实际应用中，若是射频器件的发射结束时间小于20s，则采用方程(2)中的第一个公式进行计算，而射频器件的结束发射时间大于等于20s，则采用方程(2)中的第二个公式进行计算。
需要说明的是，由于假设预设工作器件为射频器件，而该射频器件的温度采集值一般是通过设置于射频器件上的温度传感器采集得到的，对应的是射频器件的温度，不宜直接以射频器件的温度作为电池的环境温度，而通过以上述方式获得温度补偿方程对温度采集结果进行修正，能够使得所得到的环境温度更贴近实际环境温度。同时，也无需对电池所属终端增设任何器件，就能实现对电池的剩余电量检测，并且保证了检测结果的准确性。
可选地，在本申请提供的另一实施例中，请参见图11，执行步骤S102、从预存的不同温度状态组合下的电池充放电曲线中，确定与环境温度和终端的当前工作状态存在对应关系的电池充放电曲线，作为目标曲线的具体过程如下：
S301、将终端的当前工作状态等效成电池所带负载的状态。
其中，若电池的所属终端为对讲机，则将终端的当前工作状态等效成电池所带负载的状态具体如下：
a、若终端的当前工作状态为发射状态，则确定电池当前所带负载的状态为第一状态。
b、若终端的当前工作状态为接收状态或者待机状态，则确定电池当前所带负载的状态为第二状态。
换言之，在实际应用中，将终端处于发射状态等效为一种电池负载情况，将终端处于接收状态或者待机状态等效为另一种电池负载情况。
例如，可以将终端处于发射状态，等价于电池的当前负载为0.2C时；将终端处于待机状态或者接收状态时，等价于电池的当前负载为0.2A。其中，在待机状态或者接收状态下，等价后电池的电压与电量关系可如图12所示。
当然，终端状态与负载等价的情况并不仅限于上述，无论将终端状态与负载之间如何等价，均属于本申请的保护范围。
S302、依据等效结果以及环境温度，从预存的不同温度状态组合下的电池充放电曲线中，查找与等效结果以及环境温度相对应的电池充放电曲线，作为目标曲线。
其中，将电池的当前工作状态等效成电池所带负载的状态后，就能根据电池所带负载状态和环境温度，从预存的不同温度状态组合下的电池充放电曲线中，查找与当前负载状态和环境温度相对应的电池充放电曲线。
同理，假设将终端处于发射状态时，等价于电池的当前负载为0.2C，并且环境温度为20℃。进而在全部预存的电池充放电曲线中，所查找曲线应该是负载为0.2C、环境温度为20℃对应的曲线，作为目标曲线。
可选地，在本申请提供的另一实施例中，请参见图13，执行步骤S104、结合与目标曲线对应的电压电量关系表，确定当前电压对应的电池电量值的具 体过程为：
S401、依据目标曲线调用相应的电压电量关系表。
由上文可知，电压电量关系表用于表征电池在不同温度状态组合下，电池中电压与电量的对应关系。
其中，电压电量关系表中的各个电压的取值，可以不是将目标曲线根据充放电时间按照传统时间单位进行划分的，而是将目标曲线根据充放电时间进行预设个数的等分后得到的。
具体的，该预设个数可以是100，也可以是其他的正整数，本申请对该预设个数不作具体限定，无论该预设个数取何值，均属于本申请的保护范围。
下面通过一个具体实例，对电压电量关系表中的各个电压的取值，是将目标曲线根据充放电时间进行预设个数的等分后得到的作进一步的解释和说明：
结合图14和图15可知，电池充放电曲线描述的是电压与容量之间的关系。其中，电池处于放电状态时，电压会随着电量的流失逐渐下降。
当电池在环境温度为20℃，负载电流为0.2C时，对应的电池充放电曲线为图14；当电池的环境温度为0℃，负载电流为0.2A时，对应的电池充放电曲线为图15。
如图14和图15所示，可知通过电压能够确定电池的剩余容量，而放电时间t能够依据公式
Figure PCTCN2020113689-appb-000005
得出。其中，C表示电池容量(单位mA.h)，In表示平均负载电流(单位mA)。
此处假设目标曲线为图14所示的充放电曲线，则通过公式
Figure PCTCN2020113689-appb-000006
进行计算，可以得到目标曲线中电压随时间变化的曲线，如图16所示。
若是，将目标曲线根据充放电时间以100份等分的方式进行划分，就能得到该目标曲线对应的电压电量关系表，如图17所示。
需要说明的是，将目标曲线根据其充放电时间按照预设数份，例如上述的100份，进行划分，能够得到预设数份对应的电压电量关系表，该预设数越小，该电压电量关系表中对于时间的划分越精细。依据时间细分后的电压电量关系对电池的剩余电量进行检测，能够有效提高检测结果的准确度。
基于上述原理，就能根据目标曲线对相应的电压电量关系表进行调用。在实际应用中，可以预先将电池中各个电池充放电曲线按照述方式进行计算，提前得到该电池中各个充放电曲线对应的电压电量关系表；当然，也可以在检测电池剩余电量的过程中，对实时获得的目标曲线进行相应计算得到。
需要说明的是，相较于实时对目标曲线进行相应计算获得电压电量关系表的方式，根据目标曲线直接调用电压电量表的方式不仅能缩短检测时间，还能减少电池的能耗。
S402、根据电压电量关系表中电压与电量的对应关系，确定当前电压对应的电池电量值。
实际应用中，以电池的当前电压对电压电量关系表进行查找，就能得到与当前电压对应的电量，以此确定出当前电压对应的电池电量值。
值得说明的是，现有技术中还存在另一种检测电池电量的方法，结合图18，该方法根据负载电阻两端的电压值确定当前的工作电流，通过工作电流对纪录有充放电状态下电压与电量的对应关系的电压电量对应表进行插值变换，而获得当前电池的电量值。但是，由于负载电阻会进行分压，阻值越高分压越大，因此该现有方案需要一个极低阻值的电阻作为负载电阻，一般为5-10毫欧，此外，该负载电阻的阻值需要具有一定的高精确性。若是标称为5毫欧的电阻，假设有1毫欧的偏差，依据该偏差所确定的工作电流也会存在20％的偏差，因此该方案误差较大。而本申请提供的方案，无需通过负载电阻两端的电压值确定当前的工作电流，能够避免采用负载电阻自身误差所导致检测结果误差过大的问题，保证了对剩余电量检测的准确度。
并且，该现有方案除了需要高精度、低阻值的负载电阻外，还需要一个极高精度的ADC(Analog-to-digital converter，模拟数字转换器)对负载电阻两端的电压进行采样，而本申请无需额外增设任何器件，即可获取到当前电压对应的电量值，进一步降低了制造所需的硬件成本。再者，使用负载电阻还会消耗一定的电量，降低电池的使用时间，而本申请无需使用负载电阻，还能够进一步延长电池的续航时间。
在实际应用中，由于电池所属终端为对讲机时，其中的射频器件，即RFPA(radio frequency power amplifier，射频功率放大器)，在发射状态或者接收状态时会产生一个较大的电流，导致电池的电压出现压降，进而使得对电池的电压进行检测时，所获得的当前电压比实际值小0.2-0.3V。
也即，电池所属终端处于发射状态或者接收状态时，电池电压均存在抖动情况。具体的，实际的电池电压的变化情况，可分别如图19和图20所示。图19为电池所属终端处于发射状态时，对电池电压进行采集后得到的电压变化曲线图，图20为电池所属终端处于接收状态时，对电池电压进行采集后得到的电压变化曲线图。
对此，在图1的基础之上，请参见图21，本申请另一实施例在执行步骤S103、获取电池的当前电压之后，还用于执行步骤S501，以解决因检测得到的当前电压与实际值存在误差，导致检测结果准确性低的问题。
S501、通过滑动滤波算法，消除当前电压的抖动。
具体的，可以通过滑动滤波算法获取预设个数的电压值，并将所有获取到的电压值中半数且最小的数据去除，再对剩余数据求平均值的方式，消除当前电压的抖动。
例如，可以是每秒采集一次电池的当前电压，并使用滑动窗口连续纪录50个电压数据，去掉其中25个最小的电压数据，对剩余的25个电压数据求平均值，以达到消除抖动的目的。
在本实施例中，在消除当前电压的抖动之后，能够减小因RFPA功率发生突变所导致的当前电压与实际电压之间误差过大的问题，进而能够大幅度提高根据当前电压获得对应电压值的精度，也能够大幅度提升用户的使用体验感，增加客户满意度，提升了产品的竞争力。
还值得说明的是，现有技术还存在一种通过简单测量电池的电池电压，并依据该电池电压进行估算的方式，以获得该电池的电池剩余电量。具体的，此种测量方式主要依据电池在放电过程中，电池的电压会随着电池电量的流失逐渐下降这一特征，得到一个比较简单而有效的电压电量对应关系。一般情况下，此种测量方式通过电池的放电曲线，对时间进行4等份的方式进行电量划分， 就能在电子产品上显示4格电池图标，每格的精度为25％。但是，该种测量方式在使用过程中，依然会受到RFPA的功率发生突变的干扰，导致所获取的电池电压误差过大的问题。
而本实施例提供的上述方案，通过滑动滤波算法，能够消除当前电压的抖动值，减少了当前电压与实际电压之间的误差，避免了上述问题；并且，本方案还能大幅度提升电池电量的显示精度，能够将电池电量的检测精度存在的误差从25％提升至5％以内，进而能够大大提升客户的使用体验感和满意度，也进一步提升了产品的竞争力。
需要说明的是，本方案能够应用于所有设置有电池的便携式电子设备中。并且，在应用于所有未装有电量计的电池对应的产品中时，也即，在应用于所有使用非智能电池的产品中时，无需额外购入电量计芯片，减少了所需成本。
可选地，请参见图22，本申请还提供了一种电池电量的检测装置，主要包括：存储器101和处理器102。
其中，处理器102用于运行存储器101中存储的程序。
处理器102在运行程序时执行包括：如上述任一实施例所述的电池电量的检测方法。
