技术领域

背景技术
目前，市面上日常使用的电池可大致分为两种:铅酸电池、锂电池；其中，铅酸电池较具有价格低、安全可靠、放电稳定的优点，因此具有良好的市场应用范围，广泛用作车载电池。铅酸电池的总容量是电池剩余电量计算的基础，而铅酸电池的剩余电量(SOC)能直观地显示电池状态，会直接影响用户对车辆和电池的使用，所以有必要提高电池总容量的准确性，以提高电池剩余电量的计算精度，从而提升用户体验并提高电池的使用效率。但铅酸电池受制作工艺、温度变化、电池老化等问题影响，电池的实际总容量变化较大与标称容量不符，且较难确定。
传统的电池总容量标定采用恒流放电的方法，即对一组电池使用0.5C电流进行恒流放电，直到电压降低到截止电压，在此过程中释放的总容量为电池总容量；但实际应用场景中电池的放电电流不断变化，同时由于铅酸电池电压与电流的特性关系--放电电流越小到达截止电压时所能释放的容量越多；导致恒流工况下标定的电池总容量无法匹配实际工况，电池释放的总容量与标称的容量差异较大，电池总容量数据错误会导致剩余电量(SOC)的计算出现异常；容易出现显示剩余电量较高时电池无法放电、剩余电量较低时电池仍能持续长时间放电、或者充满电后剩余电量仍显示较低的现象，导致用户在日常使用中未能对电池及时充电或者电池充满电后持续充电，引起对电池的过放、过充问题，严重影响电池寿命及使用安全。

其中，待测电池是指需要测算总容量的电池；输入的电池电流是指待测电池充电输入电能时待测电池的回路的电流值，输出的电池电流是指待测电池放电输出电能时待测电池的回路的电流值。由于待测电池可能处于充电或放电的不同状态，因此，根据待测电池状态的不同，实时获取输入待测电池或者所述待测电池输出的电池电流。获取电池电流的方式有多种，例如在待测电池的充电回路或是放电回路中连接电流表等，在此不对获取电池电流的方式做具体限定，只是举例说明。
S120、基于所述电池电流确定在所述预设时长输入所述待测电池或所述待测电池输出的电池容量。
其中，输入的电池容量是指待测电池充电时接收的电量，输出的电池容量是指待测电池放电时给其他用电器可以放出的电量。根据当前电池电流的不同，相应的输入或输出的电池 容量也会相应的不同，因此，可根据电池电流确定不同情况下预设时长输入所述待测电池或所述待测电池输出的电池容量。
S130、获取所述待测电池的老化补偿信息、温度补偿信息以及当前剩余电量。
其中，老化补偿信息是指反映待测电池老化程度的信息。温度补偿信息是指反映待测电池的当前温度情况的信息。待测电池的当前剩余电量(SOC，State of Charge)是代表电池剩余可用容量占总容量的百分比，是电池管理系统中最为重要状态之一，为电动汽车的电池安全管理、充放电控制、整车能量管理等功能提供重要参考。确定当前剩余电量的方法可为多种，例如开路电压法、安时积分法、内阻法、卡尔曼滤波法、神经网络法等，在此不对确定当前剩余电量的具体方式做限定。
S140、基于所述待测电池的老化补偿信息、温度补偿信息、输入或输出的电池容量和当前剩余电量确定所述待测电池的电池总容量。
其中，由于电池的当前总容量通常与输入或输出的电池容量和当前剩余电量相关，同时，电池的老化程度和当前温度情况也会影响电池的总容量的计算精度，因此，基于待测电池的老化补偿信息、温度补偿信息、输入或输出的电池容量和当前剩余电量确定的待测电池的电池总容量较为精准，能够较为准确的反应电池的当前总容量。
上述方案，通过获取输入待测电池或者所述待测电池输出的电池电流；并基于所述电池电流确定在所述预设时长输入所述待测电池或所述待测电池输出的电池容量；然后获取所述待测电池的老化补偿信息、温度补偿信息以及当前剩余电量；最后基于所述待测电池的老化补偿信息、温度补偿信息、输入或输出的电池容量和当前剩余电量确定所述待测电池的电池总容量，从而无需进行电池总容量标定的繁琐步骤，实时获取待测电池在充放电过程中的电池电流，针对电池运行状态及使用工况的变化，能及时刷新输出的电池总容量，可降低电池老化、温度变化对总容量计算带来的影响，计算出较为精准的总容量。
在本申请的示例实施例中，所述获取所述待测电池的老化补偿信息，包括：
获取当前时刻的所述待测电池的电池内阻Ri和当前时刻所述待测电池的使用总时间t，所述当前时刻为获取所述电池电流对应的时刻；
所述待测电池的老化补偿信息通过下式确定：
Figure PCTCN2022102667-appb-000001
其中，R0为预设电池内阻最小值，t0为预设电池允许使用时长最大值，Kr为老化补偿信息，Ri为当前电池内阻，α＞0、β＞0。
其中，当前时刻的所述待测电池的电池内阻是指电池在此刻的工作状态下，电流流过电池内部所受到的阻力，它包括欧姆内阻和极化内阻，极化内阻又包括电化学极化内阻和浓差极化内阻。当前时刻所述待测电池的使用总时间是指待测电池从开始使用到此刻的处于工作状态的时间，预设电池允许使用时长最大值是指预设的待测电池的最长寿命。
α和β为实验测得的工程系数，当前电池使用总时间t越大、当前电池内阻Ri越大，老化程度越严重，Kr越小；当Ri＞2*R0，或t＞t0时，待测电池已深度严重老化，此时令Kr＝0。 因此，通过知晓当前时刻的所述待测电池的电池内阻Ri和当前时刻所述待测电池的使用总时间t，可方便的计算出待测电池的老化补偿信息，老化补偿信息的计算较为方便精准。
在上述实施例的基础上，所述获取所述待测电池的老化补偿信息之前，包括：
确定所述电池内阻Ri是否大于2倍的预设电池内阻最小值R0；或所述使用总时间t是否大于t0。
响应于确定所述电池内阻Ri大于2倍的预设电池内阻最小值R0；或所述使用总时间t大于t0，老化补偿信息为0。
其中，电池都有一定的寿命，使用总时间越大以及电池内阻越大，说明电池老化程度越严重。预设电池内阻最小值是指提前预设的待测电池电阻处于初始使用状态时电池的内阻值，当电池内阻Ri大于2倍的预设电池内阻最小值R0或使用总时间t大于预设电池允许使用时长最大值t0时，说明电池已深度严重老化，故此时可执行电池已深度老化，令老化补偿信息为0的步骤，及时得知待测电池的老化情况。
在本申请的示例实施例中，所述获取所述待测电池的温度补偿信息，包括：
获取当前时刻的所述待测电池的当前温度Ti，并通过下式确定所述待测电池的温度补偿信息。
Figure PCTCN2022102667-appb-000002
其中，T0为预设电池运行温度，Ti为电池当前温度，Kt为温度补偿信息。
其中，电池当前温度是指电池处于当前工作状态时的温度，预设电池运行温度是指电池处于正常运行情况时的温度。当电池当前温度大于预设电池运行温度时，说明电池温度在升高，电池总容量增加，当电池当前温度小于预设电池运行温度时，说明电池温度在降低，电池总容量减少，因此，根据电池当前温度和预设电池运行温度能够方便的确定所述待测电池的温度补偿信息。
当Kt＞1，代表电池温度升高，电池总容量增加；当Kt＜1，代表电池温度降低，电池总容量减少，故根据上述公式能够方便的得到待测电池的温度补偿信息。

S210、获取输入待测电池或者所述待测电池输出的电池电流。

响应于确定所述容量补偿信息超出预设容量补偿范围，执行步骤S250，响应于确定所述容量补偿信息没有超出预设容量补偿范围，执行步骤S260和S270。
其中，所述容量补偿信息为K＝ε*Kr+γ*Kt；其中，γ＞0、ε＞0。
电池老化程度越高，电池总容量会越低，电池温度升高，电池总容量增加，电池温度降 低，电池总容量减少。故电池的老化程度和温度情况均会对实际的电池总容量造成影响，容量补偿信息是指补偿电池的老化程度和温度情况对实际的电池总容量造成偏差的信息。
γ和ε为根据电池特性，实验测试所得的补偿系数权重。通过上述公式，在知晓老化补偿信息Kr和温度补偿信息Kt的情况下，能够方便精准的得到容量计算补偿信息，进而使输出的电池总容量可信度高。
预设容量补偿范围的指电池总容量可信时容量补偿信息的波动范围。
S250、将所述历史电池总容量作为电池总容量输出。
S260、通过电池总容量计算公式计算所述电池总容量。

Figure PCTCN2022102667-appb-000003
其中，SOC为当前剩余电量，K为容量补偿信息，Ci为输入或输出的电池容量，C为所述电池总容量。
总容量计算公式是指能够反应如何通过容量补偿信息、输入或输出的电池容量和当前剩余电量得到电池计算总容量的具体算法，通过上述的电池总容量计算公式，在知晓容量计算补偿信息、输入或输出的电池容量和当前剩余电量的情况下，能够方便精准的计算得到电池总容量。
S270、输出所述电池总容量。
其中，当容量补偿信息超出预设容量补偿范围，说明此时计算得到的电池总容量值不可信，例如在一个示例实施例中，预设容量补偿范围为[Kmin，Kmax]，容量补偿信息K满足K＞Kmax或K＜Kmin时，认为此时计算的电池总容量不可信，保持历史电池总容量数值；此时将所述历史电池总容量作为电池总容量输出。当容量计算补偿信息未超出预设容量计算补偿范围，说明此时计算得到的电池计算总容量值可信，从而将通过电池总容量计算公式计算出的电池总容量作为电池总容量输出。故能够使输出的电池总容量较为精准。
图3为本申请另一实施例提供的一种电池总容量计算方法的流程图，本申请实施例在前述实施例的基础上进行细化。如图3所示，所述方法包括：
S310、获取输入待测电池或者所述待测电池输出的电池电流。
S320、基于所述电池电流确定在所述预设时长输入所述待测电池或所述待测电池输出的电池容量。

响应于确定所述电池总容量超出预设电池容量范围，执行步骤S350，响应于确定所述电 池总容量没有超出预设电池容量范围，执行步骤S380。
其中，预设电池容量范围的指计算出的电池总容量可信时得到的总容量值的波动范围，当电池总容量超出预设电池容量范围，说明此时计算得到的电池总容量值不可信，例如在一个示例实施例中，预设电池容量范围[Cmin，Cmax]，电池总容量C满足C＞Cmax或C＜Cmin时，认为此时计算的电池总容量不可信，保持历史电池总容量数值；此时将所述历史电池总容量作为电池总容量输出。当电池总容量未超出预设电池容量范围，说明此时计算得到的电池总容量值可信，从而将电池总容量输出。故能够使输出的电池总容量较为精准。
S380、输出所述电池总容量。
在本申请的示例实施例中，所述基于所述电池电流确定在所述预设时长输入所述待测电池或所述待测电池输出的电池容量，包括：

其中，η为充放电效率，i为电池电流，Ci为输入所述待测电池或所述待测电池输出的电池容量。
其中，通过上述公式，能够方便精准的计算出输入或输出的电池容量。
在本申请的示例实施例中，所述获取所述待测电池的当前剩余电量包括：
获取所述电池电流、历史剩余电量和历史电池总容量，并通过下式确定待测电池的当前剩余电量；
Figure PCTCN2022102667-appb-000004
其中，SOC为当前剩余电量，SOC 0为历史剩余电量，C 0为历史电池总容量，i为电池电流。
其中，历史剩余电量是指上一次计算得到的剩余电量，历史电池总容量是指上一次输出的电池总容量。通过上述公式，能够方便的计算出当前剩余电量。
在本申请的示例实施例中，所述方法还包括：
在当时时刻的下一时刻计算重新计算所述电池总容量时，基于当前时刻的电池总容量作为历史电池总容量计算下一时刻的当前剩余电量。
例如，在一个示例实施例中，预设总容量为提前预设的电池的总容量，电池安装在车辆上，当车辆第一次启动时，可通过预设总容量作为C 0计算出当前剩余电量SOC，进而得到第一次输出的电池总容量并将电池总容量输出在车辆的显示设备上，当车辆第二次启动时，将车辆第一次启动计算得到的当前剩余电量SOC作为历史剩余电量SOC 0，将车辆第一次启动输出的电池总容量作为C 0，进而计算出车辆第二次启动时的当前剩余电量SOC。因此，通过上述方式，能够方便精准的计算出当前剩余电量。同时，在日常使用时能实时更新当前剩余电量，进而能实时更新总容量，具有时效性。
在本申请的示例实施例中，所述获取输入待测电池或者所述待测电池输出的电池电流之 后，还包括：
确定所述电池电流是否超出预设电流范围；响应于确定所述电池电流超出预设电流范围，判断电池为故障状态，结束电池总容量计算流程。
其中，预设电流范围是指电池处于正常运行状态下电流的波动范围，例如预设电流范围为[Imin，Imax]，当电池电流I超出该范围时，判断电池此时为故障状态，从而结束总容量计算流程，不再执行后续流程计算出电池总容量。当电池电流未超出预设电流范围，可继续执行计算出电池总容量的步骤。在一个示例实施例中，电池电流超出预设电流范围时可将历史电池总容量作为电池总容量输出。通过此方案，能够避免待测电池在故障时仍计算电池总容量。

实时获取输入待测电池或者所述待测电池输出的电池电压；确定所述电池电压是否超出预设电压范围；响应于确定所述电池电压超出预设电压范围，判断电池为故障状态，结束电池总容量计算流程。
其中，输入的电池电压是指待测电池充电输入电能时待测电池的回路的电压值，输出的电池电压是指待测电池放电输出电能时待测电池的回路的电压值。由于待测电池可能处于充电或放电的不同状态，因此，根据待测电池状态的不同，获取输入待测电池或者所述待测电池输出的电池电压。获取电池电压的方式有多种，例如在待测电池的充电回路或是放电回路中连接电压表等，在此不对获取电池电压的方式做具体限定，只是举例说明。
预设电压范围是指电池处于正常运行状态下电压的波动范围，例如预设电压范围为[Vmin,Vmax]，当电池电压V超出该范围时，判断电池此时为故障状态，从而结束总容量计算流程，不再执行后续流程计算出电池总容量。当电池电流未超出预设电压范围，可继续执行计算出电池总容量的步骤，以便计算出电池总容量。在一个示例实施例中，电池电压超出预设电压范围时可将历史电池总容量作为电池总容量输出。通过此方案，能够避免待测电池在故障时仍计算电池计算总容量。
