具体实施方式
下面将结合附图，对本申请实施例进行详细描述。
本申请实施例提供的技术方案可以应用于终端设备领域。终端设备通常需要电池来支持设备的正常使用，因此如何增加终端设备的电池存储容量具有十分重要的研究意义。一方面，可以考虑在终端设备中为电池配置更大的放置空间，以达到通过增大电池的体积来增加电池存储容量，然而鉴于终端设备的硬件结构限制，对电池存储容量的增加是有限的。另一方面，还可以从电池的制备手段方面来进行考虑，通过改进电池的制备方式，以实现相同体积的电池可以具备更大的电池存储容量。
目前终端设备中使用的电池通常为锂离子电池，其中，锂离子电池主要由正极材料、负极材料、电解液、外壳等部分所组成，而主要影响电池存储容量和能量的部分在于电池的正负极材料。凭借石墨具有相对较为稳定且对低压不敏感等特性，当前市场上主流的终端设备一般采用的负极材料为石墨。
在一些示例中，若采用硅作为电池的负极材料，硅负极电池相比于石墨负极电池，在同等条件下可以具有更大的电池存储容量；例如，以电池存储容量为2300毫安时(mAh)的石墨负极电池为例，若将电池的负极材料更换为硅，电池存储容量可增加约140mAh。然而，由于硅负极电池存在放电平台低、低电压时容量衰减增加以及充放电循环时易膨胀等特点，导致硅负极电池无法得到较优的应用。目前的一些研究中，主要考虑采用新的制备方法或者制备材料的混合比例来提升硅负极电池的性能或降低电池膨胀的概率，然而尚未存在较优的制备手段，以使得硅负极电池得到广泛的应用。
有鉴于此，本申请实施例提供一种电池电量状态的确定方法，用以实现对如硅负极电池等电池的控制。本申请实施时，基于采集的一些电池相关使用数据，实现对电池电压数据与电池电量状态的动态映射，进而通过电池电量状态(例如可显示为电量)提供一种新的反映电池电量状态的显示方式。通过该方法，映射后的电池电量状态除了可以反映电池剩余容量的状态，还可以反映电池电压状态。例如，可实现将较低的电池电压，映射为较低的电量，以可触发终端设备的省电模式或提醒用户及时充电等操作；以及，在电池电压低于电压阈值时，可将电池电压映射为无电量的电池状态，以触发终端设备的关机等操作。这样，可防止类硅负极电池等类型的电池较长时间处于低压状态，从而导致电量的快速衰减，避免导致电池膨胀等，以提升电池的稳定性和延长电池的使用寿命等。可以理解，本申请实施例提供的方法可以适用于硅负极电池中，或者还可以适用于未来可能存在的与硅负极电池具有类似特性的其他制备手段的电池，本申请对此不作限定。
可以理解的是，本申请实施例的终端设备可以是诸如手机、平板电脑、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、上网本、智能家居设备(例如，智能电视，智慧屏，智能音箱等)、可穿戴设备(例如，手表、头盔、耳机等)、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、个人数字助理(personal digital assistant，PDA)等设备。可以理解的是，本申请实施例对终端设备的具体类型不作任何限制。

此外，在上述各实施例中，在终端设备重新启动之后，处理器230还可以重新开始采集并统计电池使用数据，一方面可以减轻数据存储的压力，另一方面还可以基于电池最新的使用数据，以得到更为准确的映射后的目标电池电量。可以理解，若终端设备更换电池，处理器230也可以重新开始采样并统计电池使用数据，并且丢弃对原电池采集并存储的电池使用数据。
另一可选的，所述终端设备还可以接收来自其他设备(例如服务器)发送的电池使用数据。其中，所述电池使用数据例如可以为所述其他设备通过其他方式获取的。可以理解，本申请实施例中，对获取所述电池使用数据的方式不进行限定。

可选的，所述预先配置的第一映射关系可用于反映不同的电池使用数据的数值与不同的电池保护电压参数的数值之间的对应关系；或还可用于反映不同的电池使用数据的范围与不同的电池保护电压参数的数值/范围的对应关系。这样，终端设备在采集到电池使用数据之后，可参照所述第一映射关系确定对应的电池保护电压参数。
示例性的，所述预先配置的第一映射关系可以为基于多组实验数据进行配置得到的。从而可以得到较优的第一映射关系。另一示例性的，终端设备还可以基于深度学习得到所述预先配置的第一映射关系，例如可以预先通过实验等方式得到多组电池使用数据与电池保护电压参数的对应关系，然后可以将多组对应关系作为训练样本进行深度学习，以得到所述第一映射关系。可以理解，在终端设备使用过程中基于所述预先配置的第一映射关系得到的电池保护电压参数，也可作为优化深度学习模型的训练样本，以提升第一映射关系的准确性。需要说明的是，本申请实施时不限定预先配置的第一映射关系的获取方式，例如所述第一映射关系也可以为根据实际业务场景自动生成的。
另一可选的实施方式中，终端设备还可以根据电池使用数据结合其他参数确定电池保护电压参数。例如，其他参数可以为终端设备的应用程序运行信息等。
本申请实施时，所述电池保护电压参数用于对与电池电量对应的原始电压参数进行变更，可实施为对原始关机电压或原始满充电压或其他电量对应的电压进行变更。可选的，若所述电池保护电压参数用于变更所述电池的目标关机电压，所述电池保护电压参数可包 括对原始关机电压进行变更的目标关机电压参数。另一可选的，若所述电池保护电压参数用于变更所述电池的目标满充电压，所述电池保护电压参数可包括对原始满充电压进行目标满充电压参数。又一可选的，若所述电池保护电压参数用于变更所述电池的目标关机电压和目标满充电压，所述电池保护电压参数可包括目标关机电压参数和目标满充电压参数。
其中，所述目标关机电压参数和所述目标满充电压参数等目标保护电压参数可具有不同的表现形式。例如，可包括以下表现形式：
(1)用于指示变更值的绝对值。例如，目标关机电压参数可表示为抬升50毫伏(mV)，或者表示为+50mV；目标满充电压参数可表示为降低100mV，或表示为-100mV。
(2)用于指示变更比例的相对值。例如，目标关机电压参数可表示为抬升1％；目标满充电压参数可表示为2％。
(3)用于指示变更之后得到的目标值。例如，目标关机电压参数可表示为3.3V；可以理解目标关机电压参数可与原始关机电压参数不同，原始关机电压参数例如可以为3.2V。目标满充电压参数可表示为4.4V，可以理解目标满充电压参数可与原始满充电压参数不同，原始满充电压参数例如可以为4.5V。
此外，所述电池保护电压参数包含的一个或多个电压参数可以为数值，或者还可以为数值范围。例如所述电池保护电压参数包含的目标关机电压参数可以为3.3V，或者也可以为3.25V～3.35V。示例性的，在终端设备周期性采集或者响应于采集指令采集电池电压时，若确定电池电压属于目标关机电压参数对应的数值范围，则可以触发终端设备的关机。
步骤402、根据所述电池保护电压参数，确定实际电池电量和目标电池电量的第二映射关系。
一种可选的实施方式中，基于第一建模参数，确定所述电池保护电压参数对应的第二映射关系；所述第一建模参数用于指示电池电压和电池电量的对应关系。示例性的，第一建模参数可表示为SOC＝f(V)，其中，SOC可表示电池电量，f(V)可表示电池电量对应的电池电压函数。
可选的，以电池保护电压参数的表现形式为前述绝对值形式作为示例，以下通过公式1-1至公式7可确定实际电池电量和目标电池电量之间的第二映射关系，如下：
100％＝SOC原始满充电量＝f(V原始满充电压)    公式1-1
0％＝SOC原始关机电量＝f(V原始关机电压)    公式1-2
SOC目标满充电量＝f(V原始满充电压-△V降低电压)    公式1-3
SOC目标关机电量＝f(V原始关机电压-△V抬升电压)    公式1-4
假设实际电池电量和目标电池电量之间的第二映射关系通过以下公式1-5来表示：
SOC目标电池电量＝±kSOC实际电池电量±b   公式1-5
其中，鉴于公式1-5中的k和b为常数，本申请不限定k和b的符号，因此第二映射关系的设定可以具有多种形式，例如公式1-5中可以包括四种形式。本申请实施例中以SOC目标电池电量＝kSOC实际电池电量-b作为示例进行介绍。可以理解，无论公式1-5中为何种形式，计算得到的第二映射关系的结果是一致的。
若将公式1-3和公式1-4分别与公式1-5组合，可得到以下公式1-6和公式1-7：
SOC目标满充电量＝kSOC原始满充电量-b   公式1-6
SOC目标关机电量＝kSOC原始关机电量-b   公式1-7
其中，SOC目标满充电量可以通过公式1-3获得，SOC目标关机电量可以通过公式1-4获得；SOC原始满充电量为100％，SOC原始关机电量为0％。因此，根据以上公式1-6和公式1-7，可以计算得到k值和b值，从而可以得到公式1-5中的第二映射关系。
另一可选的，若所述电池保护电压参数的表现形式为前述内容中介绍到的相对值形式，在公式1-1和公式1-2的基础上，则以上公式1-3和公式1-4可表示为以下公式2-3和公式2-4：
SOC目标满充电量＝f(V原始满充电压*(1-T1))   公式2-3
SOC目标关机电量＝f(V原始关机电压*(1+T2))   公式2-4
其中，所述T1表示对原始满充电压调整的相对值，例如可以通过百分数来表示，如5％，则公式2-3表示目标满充电压相比于原始满充电压被降低了5％。同理，所述T2表示对原始关机电压调整的相对值，假设为7％，则公式2-4表示目标关机电压相比于原始关机电压抬升了7％。
此外，该实施例中确定实际电池电量和目标电池电量之间的第二映射关系的实现方式可参阅上一实施例，在此不再赘述。
又一可选的，若所述电池保护电压参数的表现形式为前述内容中介绍到的目标值形式，在公式1-1和公式1-2的基础上，则以上公式1-3和公式1-4还可表示为以下公式3-3和公式3-4：
SOC目标满充电量＝f(V目标满充电压)   公式3-3
SOC目标关机电量＝f(V目标关机电压)   公式3-4
可以理解，该实施例中确定实际电池电量和目标电池电量之间的第二映射关系的实现方式也可参阅前述实施例，在此也不再赘述。
此外，第一建模参数还可以结合电池的其他数据信息来反映电池电压和电池电量的对应关系；例如其他数据信息可以包括但不限于：电流信息、温度信息。
其中，所述第一建模参数也可以预先存储在存储器240中。示例性的，第一建模参数可以为基于多组实验数据值得到的，然后预先配置在终端设备中。
另一可选的实施方式中，终端设备还可以根据所述电池保护电压参数结合其他参数，确定实际电池电量和目标电池电量的第二映射关系。例如，其他参数可以为电池温度、电池电流等信息。
步骤403、基于所述第二映射关系和所述电池的实际电池电量，确定所述目标电池电量。
可选的，处理器230可实时采集得到当前的实际电池电量，并根据实际电池电量和上 述公式1-5示出的第二映射关系得到映射后的目标电池电量。例如，处理器230可采集到实际电池电量为30％，经过映射之后得到目标电池电量为16％；可选的，若终端设备开启了电池电量低于20％自动开启省电模式。又例如，处理器230可采集到实际电池电量为10％，经过映射之后得到目标电池电量为0％；此时，终端设备的电源管理系统检测到目标电池电量显示为0，则可触发自动关机流程。
需要说明的是，本申请实施时，获取所述电池的实际电池电量可实施为持续采集用于确定所述实际电池电量的电池参数，然后根据所述电池参数确定所述电池的实际电池电量。其中，所述电池参数例如可以为电池电流、电池电压等参数。或者，还可实施为周期性采集所述电池参数，根据所述电池参数确定所述电池在当前周期的实际电池电量。又或者，还可实施为接收并响应于请求指令采集所述电池参数，根据所述电池参数确定所述电池的实际电池电量；例如，若存在应用程序或进程请求调用电池电量，则处理器230可以响应于所述应用程序或进程获取所述电池的实际电池电量。
此外，可选的，处理器230确定映射后的所述目标电池电量之后，可将映射后的所述目标电池电量传输给显示单元260进行显示，以使用户获取到映射后的目标电池电量。另一可选的，若处理器230接收到其他应用程序或进程获取电池电量的调用请求指令，可以将映射后的所述目标电池电量反馈给所述其他应用程序或进程，以实现终端设备上其他应用程序或进程的调用处理。
参阅图6，为本申请实施例提供的一种电池电量状态的确定方法的另一流程示意图。该方法可应用于终端设备，至少包括以下流程：
步骤401、根据电池使用数据确定电池保护电压参数；所述电池使用数据用于反映所述电池在预设时间段内的使用状态，所述电池保护电压参数用于对与电池电量对应的原始电压参数进行变更。
其中，步骤401的实现过程可参阅前述实施方式中介绍的内容，在此不再重复说明。
步骤402’、根据所述电池保护电压参数，确定实际电池电压和目标电池电量的对应关系。
可选的，基于预先配置的第三映射关系，将第一建模参数切换为第二建模参数；所述第一建模参数用于指示电池电压和电池电量的原始对应关系，所述第二建模参数用于指示电池电压和电池电量的目标对应关系。
其中，假设第一建模参数可表示为SOC＝f1(V)，其中，SOC可表示电池电量，f1(V)表示电池电量对应的第一电池电压函数。
示例性的，终端设备若基于采集到的电池使用数据，确定电池保护电压参数，可以理解，所述第一建模参数指示的原始电池电压和原始电池电量的对应关系已经不再适用，本申请实施时可根据所述电池保护电压参数，确定终端设备使用的第二建模参数。例如，第二建模参数可表示为SOC＝f2(V)，其中，SOC可表示电池电量，f2(V)表示电池电量对应的第二电池电压函数。
可选的，所述电池保护电压参数包括但不限于关机电压目标参数、满充电压目标参数中的一种或组合。以所述电池保护电压参数中包括所述关机电压目标参数作为示例，处理器230可以基于所述关机电压目标参数从预先存储的第三映射关系中查到合适的第二建模 参数。其中，所述预先配置的第三映射关系可用于反映不同的电池保护电压参数的数值与不同的建模参数之间的对应关系；或还可用于反映不同的电池保护电压参数的范围与不同的建模参数之间的对应关系。需要说明的是，终端设备中可预先配置多种不同的建模参数，例如预先存储第一建模参数～第五建模参数共五种。其中，所述电池保护电压参数包括的一个或多个参数可以为参数值，也可以为参数范围。
其中，所述预先配置的第三映射关系可以存储在存储器240中。
步骤403’、基于所述对应关系和所述电池的实际电池电压，确定所述目标电池电量。
示例性的，通过图3中示出的电量计电路302可以采集电池的电压数据、电流数据、电流积分数据等电池数据中的一种或组合，基于所述第二建模参数可以计算得到电池的目标电池电量。可以理解，基于第一建模参数和第二建模参数分别指示的电池电压和电池电量的对应关系不同，因此在电量计电路302采集到电池相同的电池数据时，可以得到不同的电池电量。
通过本申请提供的方法，基于采集到的电池使用数据，为了保护电池，可根据电池的使用情况，设置对应的电池保护电压参数，进而变更电池电压和电池电量之间的映射关系，以确定映射后的电池电量状态。该方法中，不仅可以通过计算目标电池电量和实际电池电量的映射方式来实现电池电压到电池电量的映射；还可以通过变更电池电压和电池电量之间的映射关系，从而可以实现对基于电池电压映射得到电池电量。
因此，映射得到目标电池电量不仅可以反映电池的实际电池电量，还可反映电池的电压情况，从而可实现在电池电压较低时，映射得到较低的目标电池电量，可以及时地提醒用户进行充电以及避免电池更长时间的处于低压状态。因此，通过基于电池电压和电池电量的动态映射，可以较好地避免电池长时间工作在危险电压范围，例如硅负极电池在低压范围内，具有较不稳定的性能，因此在采用硅负极电池时可抬升电池关机电压；或例如若未来存在其他材料电池在其他电压范围(如高压范围)，具有较差的性能，可以通过降低电池满充电压来保护电池，延迟电池寿命。
