Description

电池的安全预警方法及装置 技术领域
本申请实施例涉及智能汽车技术领域,更具体地,涉及电池的安全预警方法及装置。
背景技术
近年来,在节能减排的大环境下,电动汽车在我国得到了快速发展。但是,伴随着电动汽车的快速发展,电动汽车的自燃事件也逐渐增多,往往导致车毁人亡的安全事故。研究表明,电动汽车自燃的大部分原因与电动汽车中的电池发生热失控有关。因此,对电动汽车中电池的安全预警成为研究热点。
目前,对电动汽车中的电池的安全预警主要有两种方式。在第一种实现方式中,由于电池在发生热失控的最初阶段会有电池冒烟、排放气体,电池内的压强增大等特点,因此通过对电动汽车增设传感器来对电池的烟雾、气体、压力等特征进行探测来识别早期的热失控现象,以实现对电池的安全预警。在第二种实现方式中,通过在电动汽车的电池管理系统(battery management system,BMS)中设定电压阈值或者温度阈值,然后当电池的电压值触发到电压阈值或者温度值触发到温度阈值时就触发报警,以做到对电池的安全预警。
然而,在第一种实现方式中,由于电池发生热失控的最初阶段距离电动汽车自燃的时间一般时间很短,例如从电池冒烟、排放气体到电动汽车自燃的时间间隔可能只有十几分钟时间,因此,通过传感器识别早期的热失控现象可以保证安全预警的准确性,但同样是由于时间间隔很短的问题,导致安全预警的时间已经很晚。而在第二种实现方式中,由于电池的电压值触发到电压阈值或者温度值触发到温度阈值,并不代表电池就一定发生了热失控,因此,在使用电压值或者温度值进行电池安全预警时,虽然能够保证提前安全预警,但无法保证安全预警的准确性。
因此,如何提升安全预警的准确性成为亟待解决的技术问题。

第三方面,本申请提供一种电池的预警方法,应用于电池预警系统,所述方法包括:
获取目标车辆电池的N个性能值,N个性能值与目标车辆电池的N个性能一一对应,N个性能包括以下性能中的M个性能:电压偏差下降速度、绝缘下跌速度、静置压差、绝缘平均水平、循环平均温度、循环温升速率,M为正整数,N为大于或等于M的正整数;将与N个性能值中每个性能值均具有预设映射关系的电池预警信息确定为目标车辆的电池预警信息。
本实施例中,由于是将与N个性能值中每个性能值均具有预设映射关系的电池预警信息确定为目标车辆的电池预警信息的,即在确定目标车辆的电池预警信息时,是基于目标电池的N个性能值,而该N个性能值与目标电池的N个性能一一对应。此时,若N大于1,即获取到的用于描述目标电池性能的参数更全面,此外,由于获取的信息是能够用于描述目标电池的热失控的参数,相比仅获取电池的电压性能或者温度性能参数,本申请实施例中获取的目标电池的性能能够更深层次的反映出目标电池在热失控方面的状态,因此,不论是在N等于1时还是N大于1时,都能够提升电池的安全预警的准确性。
结合第三方面,在一种可能的实现方式中,将与N个性能值中每个性能值均具有 预设映射关系的电池预警信息确定为目标车辆的电池预警信息,包括:根据N个性能中每个性能的取值与取值所属的取值区间之间的预设映射关系,确定N个性能值中与每个性能对应的性能值所属的性能取值区间;将与N个性能值中每个性能值所属的性能取值区间均具有预设映射关系的电池预警信息确定为目标车辆的电池预警信息。
该实现方式中,是将与N个性能值中每个性能值所属的性能取值区间均具有预设映射关系的电池预警信息确定为目标车辆的电池预警信息的。即,在确定目标车辆的电池预警信息时,考虑的是N个取值区间,而该N个取值区间与N个性能一一对应。因此,在确定目标车辆的电池预警信息时能够更加准确。
结合第三方面,在一种可能的实现方式中,所述每个性能的取值所属的取值区间基于所述每个性能对应的预警阈值对每个性能的预设取值范围划分所得,每个性能对应的预警阈值与所述每个性能的多个历史取值满足映射关系。
本实施例中,由于每个性能对应的预警阈值不是凭借经验选取的,而是与每个性能的多个历史取值满足映射关系。因此,选取的预警阈值会更加准确,进一步地,通过该预警阈值划分出的预警区间会更加准确,从而进一步提升电池的安全预警的准确性。
结合第三方面,在一种可能的实现方式中,将与N个性能值中每个性能值的性能取值区间均具有预设映射关系的电池预警信息确定为目标车辆的电池预警信息,包括:根据N个性能中每个性能的取值区间与为每个性能划分的预警等级的之间的预设映射关系,确定N个性能值中与每个性能对应的性能值所对应的预警等级;将与N个性能值一一对应的N个预警等级中每个预警等级均具有预设映射关系的电池预警信息确定为目标车辆的电池预警信息。
该实现方式中,还可以为不同的取值区间划分预警等级,即确定不同的取值区间与预警等级之间的映射关系,然后再将与N个性能值中每个性能值均具有预设映射关系的电池预警信息确定为目标车辆的电池预警信息时,只需要将与N个性能值一一对应的N个预警等级中每个预警等级均具有预设映射关系的电池预警信息确定为所述目标车辆的电池预警信息即可。该方式中,由于预警等级能够反映出取值区间对电池的安全程度的影响,对于电池预警系统,可以通过某个性能对应的预警等级更快地确定出该性能对电池的安全程度的影响的程度。
结合第三方面,在一种可能的实现方式中,所述目标车辆的电池预警信息包括以下预警信息中的至少一种:一级预警信息、二级预警信息或者三级预警信息。
结合第三方面,在一种可能的实现方式中,所述一级预警信息指示所述目标车辆可继续使用,所述二级预警信息指示所述目标车辆需要进行功能故障维修操作,所述三级预警信息指示所述目标车辆需要进行紧急处理操作。
结合第三方面,在一种可能的实现方式中,电池预警系统中存储不同的安全预警等级与不同的处理设备对应的处理策略之间的映射关系,所述方法还包括:从所述映射关系中获取目标处理设备在所述目标车辆的电池预警信息下对应的目标处理策略;向所述目标处理设备发送所述目标处理策略信息和所述目标安全预警等级信息。
示例性地,所述目标处理设备包括以下一种:所述目标车辆、充电桩、换电站和手机。
该实现方式中,电池预警系统可以根据不同的安全预警等级自动分配处理措施, 可以实现保障同一个车辆、同一个电池在不同处理设备之间的处理措施得当、步调一致。
第四方面,本申请提供一种处理设备,该处理设备包括用于执行如第一方面其中任意一种可能的实现方式所述的模块。
第五方面,本申请实施例提供一种电池的安全预警装置,该装置包括用于执行如第二方面或其中任意一种可能的实现方式所述的方法的模块,执行如第三方面或其中任意一种可能的实现方式所述的方法的模块。

具体实施方式
近年来,在节能减排的大环境下,电动汽车在我国得到了快速发展。但是,伴随着电动汽车的快速发展,电动汽车的自燃事件也逐渐增多,往往导致车毁人亡的安全事故。研究表明,电动汽车自燃的大部分原因与电动汽车中的电池发生热失控有关。因此,对电动汽车中电池的安全预警成为研究热点。
图1为本申请一个实施例提供的应用场景的示意图。如图1所示,该场景中包括车辆100和电池预警系统101。
其中,车辆100中包括电池,该电池的电能可以驱动车辆100行驶。一般情况下,电池安装在车辆100的底盘上。可以理解的是,在电池的充放电过程中,电池可能发生热失控,导致电池起火,甚至会引起整车的燃烧,从而造成安全事故。
因此,为了降低关于车辆的安全事故的发生率,通常使用电池预警系统101对车辆100中的电池进行安全预警,例如,当安全预警系统101确定车辆100中的电池可能马上发生热失控时,就触发车辆100中的报警器进行报警,以确保车辆100以及车辆100中的电池的安全性。
在此说明的是,本申请实施例电池预警系统101的具体部署方式不做限定。例如,电池预警系统101可以部署在车辆100的内部,或者也可以部署在服务器,服务器包括本地服务器或云端服务器。
目前,在图1所示的应用场景中,电池预警系统101在对车辆100中的电池进行安全预警时主要有两种方式。在第一种实现方式中,由于电池在发生热失控的最初阶段会有电池冒烟、排放气体,电池内的压强增大等特点,因此通过在车辆100中增设传感器来对车辆100中的电池的烟雾、气体、压力等特征进行探测来识别早期的热失控现象,然后当识别到热失控现象后,例如可以触发车辆100中的报警器进行报警,以实现对电池的安全预警。在第二种实现方式中,通过在车辆100中的电池管理系统(battery management system,BMS)中设定电压阈值或者温度阈值,然后当电池的电压值触发到电压阈值或者温度值触发到温度阈值时就触发车辆100中的报警器进行报警,以做到对电池的安全预警。
但是,在第一种实现方式中,由于车辆100中的电池发生热失控的最初阶段距离车辆100自燃的时间一般时间很短,例如从电池冒烟、排放气体到车辆100自燃的时间间隔可能只有十几分钟时间,因此,通过传感器识别早期的热失控现象可以保证对电池的安全预警的准确性,但同样是由于时间间隔很短的问题,导致安全预警的时间已经很晚。示例性地,车辆100中的电池已经发生了热失控现象才去进行安全预警。
而对于上述第二种实现方式,由于车辆100中的电池的电压值触发到电压阈值或者温度值触发到温度阈值,并不代表辆100中的电池就一定发生了热失控,例如,通过检测车辆100中的电池的电压进行预警时,由于电池发生热失控时,其电压变化较小,与正常电池的电压变化相混淆,区分困难。因此,通过使用电压值或者温度值进行安全预警时,虽然能够保证提前安全预警,但无法保证安全预警的准确性。
鉴于此,本申请实施例提供一种电池的安全预警方法及装置。本申请提供的方法中,电池预警系统在确定目标车辆的电池预警信息时,首先获取目标车辆电池的N个性能值,然后将与N个性能值中每个性能值均具有预设映射关系的电池预警信息确定为目标车辆的 电池预警信息。此外,在确定出目标车辆的电池预警信息后,能够基于不同的安全预警等级与不同的处理设备对应的处理策略之间的映射关系,向目标处理设备发送目标处理策略信息,相应地,目标处理设备在接收到目标处理策略信息后可以根据目标处理策略信息的指示执行相应地操作。该技术方案中,可以提升电池的安全预警的准确性,并且还能够实现电池预警系统与多个目标处理设备之间的协同。
图2为本申请一个实施例提供的电池的安全预警方法的流程性示意图。如图2所示,本申请实施例的方法包括S201和S202。本申请中的方法可以由图1中的电池预警系统101执行。
S201,获取目标车辆电池的N个性能值,所述N个性能值与所述目标车辆电池的N个性能一一对应,所述N个性能包括以下性能中的M个性能:电压偏差下降速度、绝缘下跌速度、静置压差、绝缘平均水平、循环平均温度、循环温升速率,M为正整数,N为大于或等于M的正整数。
其中,电压偏差下降速度是指车辆在静置状态时电池中的电芯的电压在某个时段内偏离车辆在静置状态时电池中的电芯的平均电压的速度。
其中,静置状态可以认为是电池的电流被限制在某个范围内时的车辆的状态。例如车辆在等待红灯或者车辆停在路边时对应的电池的电流都很小,此时,可以认为车辆在等待红灯或者停在路边时的状态为静置状态。
绝缘下跌速度是指车俩在行驶状态或者静置状态下时电池的绝缘水平在某个时段内的下降速度,例如电池的绝缘水平在每小时下的下降速度。
静置压差是指车辆在静置状态时电池中的电芯的电压与车辆在静置状态时电池中的电芯的平均电压之差。在此说明的是,本实施例对如何获取电池中的电芯的平均电压不做限定。例如在一种可能对实现方式中,可以总共获取M个车辆的静置压差,该M个车辆属于同一个车型和属于相同的运营模式、且均在同一个地区,然后通过对获取到的该M个车辆的静置压差值计算平均值,以获得静置状态时电池中的电芯的平均电压。
绝缘平均水平是指车辆在行驶状态或者静置状态时的电池在某个时段的绝缘平均水平。
循环平均温度是指车辆在某个时段内的电池的平均温度。
循环温升速率是指车辆在某个时段内使用的平均温升速率。
可以看出,电压偏差下降速度、绝缘下跌速度、静置压差、绝缘平均水平、循环平均温度和循环温升速率这6个性能中的任意一个性能若发生异常,都可能影响电池发生热失控现象。因此,本申请中,在对目标车辆电池进行安全预警时,可以获取目标车辆电池在的上述6个性能中的任意M个性能的性能值,例如可以全部获取,又或者可以将上述6个性能按照影响目标电池的安全性的重要程度进行排序,然后选取前面几个比较重要的性能。
此外,本实施中,获取的N个性能值还可以是关于目标车辆电池的其他性能对应的性能值,即不是上述6个性能中的任意一个性能的性能值,即N大于M。例如还可以包括目标车辆电池的温度值。本申请实施例对此不做限定。
在此说明的是,为了便于描述,本申请中也将目标车辆电池称为目标电池,不构成对本申请实施例的限制。
S202,将与N个性能值中每个性能值均具有预设映射关系的电池预警信息确定为目标车辆的电池预警信息。
其中,电池预警信息用于指示车辆电池的安全程度。示例性地,可以对电池预警信息划分等级,例如当电池预警信息为一级预警信息时,认为车辆电池相对安全,不会引起热失控,当电池预警信息为二级预警信息时,认为车辆电池可能会引起车辆电池的热失控,此时可以发送报警信息,当电池预警信息为三级预警信息时,认为车辆电池已经很不安全,一定会引起车辆电池的热失控,此时也可以向用户或者车辆发送提示信息。
可以理解的是,电压偏差下降速度、绝缘下跌速度、静置压差、绝缘平均水平、循环平均温度、循环温升速率中的任意一个性能发生异常都可能影响电池发生热失控现象,即影响电池的安全,而某个性能是否发生异常可以根据该性能的性能值反映出来。因此,本实施例中,可以在电池预警信息中存储N个性能值与电池预警信息之间的预映射关系,然后对于目标车辆电池,当获得了目标电池的N个性能值之后,可以根据预映射关系确定出该目标车辆中的目标车辆的电池预警信息。
作为一种示例,在N=1时,即获取的是一个性能值,现以获取的是循环平均温度为例,假设认为电池正常时的循环平均温度为0度到40度,电池异常时的循环平均温度为大于40度,即循环平均温度在0度到40度时认为电池安全,大于40度时认为电池不安全,此时就可以在电池预警系统中存储以下预映射关系:若电池的循环平均温度在0度到40度,对应的电池预警信息为一级预警,若电池的循环平均温度大于40度,对应的电池预警信息为二级预警。在这种情况下,现假设电池预警系统获取到的目标车辆的目标电池的循环平均温度为60度,此时就可以基于电池预警系统存储的上述预映射关系确定出目标电池的电池预警信息为一级预警。更进一步地,可以向用户或者车辆输出提示信息,提示当前电池的安全预警信息为一级预警。
作为另一种示例,当N大于1时,即获取的是多个性能值,现以获取的是循环平均温度和循环升温速率为例,假设认为电池正常时的循环平均温度为0度到40度,电池异常时的循环平均温度为大于40度,即循环平均温度在0度到40度时认为电池安全,大于40度时认为电池不安全,而对于循环升温速率,假设认为电池正常时的循环升温速率为小于5摄氏度每分钟,电池异常时的循环升温速率为大于5摄氏度每分钟。此时就可以在电池预警系统中存储以下预映射关系:若电池的循环平均温度在0度到40度且循环升温速率为小于5摄氏度每分钟,则对应的电池预警信息为一级预警信息,若电池的循环平均温度大于40度或者循环升温速率为大于5摄氏度每分钟,则对应的电池预警信息为二级预警信息,若电池的循环平均温度大于40度且循环升温速率为大于5摄氏度每分钟,则对应的电池预警信息为三级预警信息。在这种情况下,现假设电池预警系统获取到的目标车辆的目标电池的循环平均温度为60度,且循环升温速率为10摄氏度每分钟,此时就可以基于电池预警系统存储的上述预映射关系确定出目标电池的电池预警信息为三级预警。更进一步地,可以向用户或者车辆输出提示信息,提示当前电池的安全预警信息为三级预警,即目标车辆中的目标电池很不安全。
其中,有关一级预警信息、二级预警信息和三级预警信息的描述可以参考本实施例中的相关描述,不再赘述。
本实施例中,由于是将与N个性能值中每个性能值均具有预设映射关系的电池预警信息确定为目标车辆的电池预警信息的,即在确定目标车辆的电池预警信息时,是基于目标电池的N个性能,此时,若N大于1,相当于不再是基于单个的电压或者单个的温度来确定目标车辆的电池预警信息,即获取到的关于热失控的性能参数更全面,此外,由于获取的信息是能够用于描述目标电池的热失控的参数,相比仅获取电池的电压性能或者温度性能参数,本申请实施例中获取的目标电池的性能能够更深层次的反映出目标电池在热失控方面的状态,因此,不论是在N等于1时还是N大于1时,都能够提升电池的安全预警地准确性。
作为一个可选的实施例,图2所示实施例中的S202的一种可实现方式包括:根据N个性能中每个性能的取值与取值所属的取值区间之间的预设映射关系,确定N个性能值中与每个性能对应的性能值所属的性能取值区间;将与N个性能值中每个性能值所属的性能取值区间均具有预设映射关系的电池预警信息确定为目标车辆的电池预警信息。
可以理解的是,N个性能中的每个性能都可能会影响电池发生热失控现象,而电池的性能是否发生异常可以根据该性能的性能值反映出来。而在一般情况下,对于某个性能,通常位于某个区间的多个性能值对应的电池的性能大致相同。因此,本实施例中,对于每个性能,可以设定每个性能的取值与取值区间之间的映射关系,然后对于N个性能,将与N个性能值中每个性能值均具有预设映射关系的电池预警信息确定为目标车辆的电池预警信息时,只需要将与N个性能值中每个性能值所属的性能取值区间均具有预设映射关系的电池预警信息确定为目标车辆的电池预警信息即可。
示例性地,以静置压差性能为例,假设静置压差值在区间[-10,-5]和[5,10]这两个区间时,其对电池的影响很大,而在区间[-5,-2]至[2,5]这个区间对应的电池的性能大致相同,则可以确定静置压差的取值与取值区间的映射关系为:静置压差值位于[-10,-5]之内的任意一个取值对应的取值区间[-10,-5],静置压差值位于[5,10]之内的任意一个取值对应取值区间[5,10],静置压差值位于[-5,-2]之内的任意一个取值对应取值区间[-5,-2],静置压差值位于[2,5]之内的任意一个取值对应取值区间[2,5]。
在这种设定了每个性能的取值与取值区间之间的映射关系的情况下,当获取到了目标电池在目标时段的某个性能值时,就可以首先根据设定的每个性能的取值与取值区间之间的映射关系获取到该性能值所属的取值区间。进一步地,对于N个性能值,就会获得N个取值区间。
本实施例中,是将与N个性能值中每个性能值所属的性能取值区间均具有预设映射关系的电池预警信息确定为目标车辆的电池预警信息。即,在确定目标车辆的电池预警信息时,考虑的是N个取值区间,而该N个取值区间与N个性能一一对应。因此,在确定目标车辆的电池预警信息时能够更加准确。
作为一个可选的实施例,每个性能的取值所属的取值区间基于每个性能对应的预警阈值对每个性能的预设取值范围划分所得,每个性能的取值所属的取值区间基于每个性能对应的预警阈值对每个性能的预设取值范围划分所得,每个性能对应的预警阈值与每个性能的多个历史取值满足映射关系。
可以理解的是,在确定N个性能中的每个性能值所属的性能取值区间时,首先应该提供取值区间。而取值区间又是基于单个值(本实施例中称为预警阈值)划分得到 的,因此,在确定每个性能的取值所属的取值区间时,首先应该确定预警阈值。
本实施例中,在确定每个性能对应的预警阈值时,是基于预警阈值与每个性能的多个历史取值满足映射关系取得的。
作为一种示例,每个性能对应的预警阈值与每个性能的多个历史取值所满足的高斯分布函数中的参数σ的值之间满足预设关系。
该示例中,每个性能的多个历史取值满足的高斯分布函数中的标准差σ的值确定出来的。即,在本实施例中,每个性能对应的预警阈值与该性能的多个历史取值满足的高斯分布函数中的标准差σ满足预设关系。
在此说明的是,本实施例对多个历史取值如何获取不做限定,例如获取的可以是前一年的历史数据,又或者可以是在前半年的历史数据。
可以理解的是,高斯分布函数一般能够描述大多数随机变量的分布情况。其中,高斯分布函数可以表示成:
Figure PCTCN2021134617-appb-000001
其中,σ表示标准差,μ表示均值,X为随机变量。
还可以理解的是,要确定出每个性能满足的高斯分布,就需要确定出σ和μ。
本实施例中,为了确定出每个性能对应的高斯分布函数中的σ和μ,通过获取该每个性能的多个历史值,然后根据多个历史值对高斯分布函数进行训练,以确定出σ和μ。
一般而言,由于N个性能中的每个性能的实际分布情况更倾向于高斯分布,因此,本实施例中,通过高斯分布确定出的预警阈值更加准确。
示例性地,每个性能对应的预警阈值与每个性能的多个历史取值所满足的高斯分布函数中的参数σ的值之间满足预设关系如下:i*σ,i为2、3或4。如图3所示,图3为本申请一个实施例提供的取值区间的结构性示意图。
如图3所示,其中的曲线表示多个历史取值训练得到的高斯分布函数。图3分别示出了预警阈值为2σ、3σ和4σ时划分的取值区间。如图3所示,该2σ、3σ和4σ划分的取值区间包括6个区间。
本实施例中,由于预警阈值不是凭借经验选取的,而是基于高斯分布选取出来的。而又由于高斯分布更贴合每个性能的性能值的真实分布情况,因此,通过高斯分布选取的预警阈值会更加准确,进一步地,通过该预警阈值划分出的预警区间会更加准确,从而进一步保证预警的准确性。
进一步地,作为将与N个性能值中每个性能值均具有预设映射关系的电池预警信息确定为目标车辆的电池预警信息的一种可实现方式,包括:根据N个性能中每个性能的取值区间与为每个性能划分的预警等级的之间的预设映射关系,确定N个性能值中与每个性能对应的性能值所对应的预警等级;将与N个性能值一一对应的N个预警等级中每个预警等级均具有预设映射关系的电池预警信息确定为目标车辆的电池预警信息。
可以理解的是,某个性能的性能值在不同的取值区间时,其对车辆电池的安全的影响程度可能是不一样的,即对电池造成的影响是有不同等级的。
因此,本实施例中,还可以为不同的取值区间划分预警等级,即确定不同的取值区间与预警等级之间的映射关系,然后对于N个性能,将与N个性能值中每个性能值均具有预设映射关系的电池预警信息确定为目标车辆的电池预警信息时,只需要将与N个性能值一一对应的N个预警等级中每个预警等级均具有预设映射关系的电池预警信息确定为所述目标 车辆的电池预警信息即可。
示例性地,对于图3所示的高斯分布,假设该高斯分布为静置压差性能所符合的高斯分布。为便于描述,将位于高斯分布中心轴左边的2σ、3σ和4σ分别表示成-2σ、-3σ和-4σ。该示例中,假设当取值区间为[-2σ,2σ]时认为电池还较安全,当取值区间为[-3σ,-2σ]以及[2σ,3σ]时认为电池可能不安全,当取值区间为[-4σ,-3σ]以及[3σ,4σ]时认为电池一定不安全。
则在实现时,可以确定取值区间[-2σ,2σ]对应的预警等级为一级,取值区间[-3σ,-2σ]以及取值区间[2σ,3σ]区间对应的预警等级为二级,取值区间[-4σ,-3σ]以及取值区间[3σ,4σ]对应的预警等级为三级。其中,预警等级的级别越高,表示电池越不安全。
上述高斯分布函数仅为示例,还可以为正太分布函数等,本申请实施例对此不作限定。
在该实现方式中,当获得了N个性能值中每个性能值后,就可以先根据N个性能中每个性能的取值区间与为每个性能划分的预警等级的之间的预设映射关系,确定出N个性能值中与每个性能对应的性能值所对应的预警等级;然后再将与N个性能值一一对应的N个预警等级中每个预警等级均具有预设映射关系的电池预警信息确定为目标车辆的电池预警信息。
作为一个可选的实施例,本实施例中的电池预警系统中还可以存储不同的安全预警等级与不同的处理设备对应的处理策略之间的映射关系,所述方法还包括:从映射关系中获取目标处理设备在目标车辆的电池预警信息下对应的目标处理策略;向目标处理设备发送目标处理策略信息和目标安全预警等级信息。示例性地,目标处理设备包括以下任意一种:目标车辆、充电桩、换电站、用户终端。
该实现方式中,电池预警系统可以根据不同的电池预警信息自动分配处理措施,可以实现保障同一个车辆、同一个电池在不同终端和角色之间的处理措施得当、步调一致。
下面,结合图4和图5,详细说明本申请实施例的一种可实现方式。
图4为本申请一个实施例提供的一种安全预警的架构示意图。如图4所示,在该架构中,包括电池预警系统401,以及车辆402、充电桩403、换电站404、用户终端405、车企售后部门406和消防机构407中的至少一项。
其中,充电桩403可以给车辆402中的电池进行充电,换电站404可以为车辆402中的电池提供充电和动力电池快速更换。用户设备405中包括能够控制车辆402的应用软件,车企售后部门406能够为服务于车辆402,例如为车辆402进行维护,消防机构407用于在车辆402发生自燃时,对车辆402进行灭火。
本实施例中,电池预警系统401部署于云端服务器中。其用于对车辆402中的电池的安全稳定运行进行监控和故障预警。
具体地,该电池预警系统401中包括数据接收端口,数据解析模块、数据仓库、模型训练模块、实时预警模块、结果耦合模块和处理指令下发模块。
其中,数据接收端口用于按照通讯协议接收车辆402的实时数据,可以理解的是,为了实现车辆402与电池预警系统401之间的通信,就需要车辆402与电池预警系统401符合通信协议,即车辆402要向电池预警系统401发送数据时,其数据封装成协议规定的格式,然后将封装后的实时数据发送给电池预警系统401。同理,若电池预警系统501要向车辆402发送数据,其原理也是一样,此处不再赘述。在此说明的是, 本实施例中的数据接收端口也可以用于接收充电桩403和换电站404中的数据,本实施例对此不做限定。
数据解析模块用于将接收到的数据解析为真实数据。示例性地,假设对于某个电流值,基于通讯协议,车辆402为了实现与电池预警系统401的通信,在发送该电流值时需要将该电流值往右偏移3位。此时,对于电池预警系统401,其接收到的数据就不是真实数据,因此为了得到真实数据,就需要将该电流值向左偏移3位。
数据仓库用于存储数据解析模块已经解析过的真实数据。在此说明的是,本申请实施例对数据仓库存储的历史数据的时段不做限制,例如可以是车辆402在过去一年的数据,又或者可以是过去半年的数据。
模型训练模块,用于基于数据仓库中存储的关于车辆401中的电池的特征信息进行模型训练,以获得预警模型。
实时计算模块,用于基于已经训练完成的预警模型,对实时解析的车辆数据进行处理计算,输出各个特征信息的计算结果。
结果耦合模块,用于将实时计算模块输出的多个特征信息的结果进行耦合,并输出最终的电池预警信息。
处理指令下发模块,用于基于电池预警信息,按照既定的处理逻辑对不同的处理设备下发处理指令。
下面,说明在图5所示的架构中,模型训练模块是如何进行训练的。本实施例以6个特征值为例进行描述。
如图5所示,电池预警系统401首先从数据仓库中确定电压偏差下降速度值、绝缘下跌速度值、静置压差值、绝缘平均水平值、循环平均温度值和循环温升速率值,如图5中的(a)所示,其中,上述6个特征中每个特征都获取M个取值。更具体地,获得的M个电压偏差下降速度值以及M个绝缘下跌速度值都是目标车辆的历史值,而或取的M个静置压差值、绝缘平均水平值、循环平均温度值和循环温升速率值均是电池预警系统401中的数据仓库中包括的与目标车辆为同车型、同地区以及通运营模式的车辆的数据。即,可以认为,通过M个电压偏差下降速度以及M个绝缘下跌速度能够用于描述目标车辆本身的情况。通过同车型、同地区以及同运营模式的车辆的数据可以用于描述同车型、同地区以及通运营模式的特征的分布情况。
然后在获取到上述特征之后,认为每个特征的分布都是符合高斯分布的,因此,通过每一个特征对应的M个特征值训练各自的高斯分布,即通过M个特征值确定出其对应的高斯分布的标准差和均值。之后,针对每一个性能对应的高斯分布,分别取2个标准差对应的取值点作为一级预警的阈值点,取3个标准差对应的取值点作为二级预警的阈值点,取4个标准差对应的取值点作为三级预警的阈值点,如图5(b)所示,为确定的一级阈值点、二级阈值点和三级阈值点的示例性。
基于此,确定出了每个性能对应的阈值点,进一步地,可以基于阈值点为每个特征划分取值区间与预警等级之间的映射关系。其中,取值区间与预警等级之间的映射关系可以参考前述实施例中的描述,此处不再赘述。
可以理解的是,当基于阈值点为每个特征划分取值区间与预警等级之间的映射关系后,便可以基于该映射关系对目标车辆中的目标电池进行安全预警。具体地,电池 预警系统401实时获取目标车辆在目标时段内的电压偏差下降速度值、绝缘下跌速度值、静置压差值、绝缘平均水平值、循环平均温度值和循环温升速率值,然后对于每个特征对应的值,基于取值区间与预警等级之间的映射关系,确定出对应的预警等级。可以理解的是,对于电压偏差下降速度、绝缘下跌速度这两个特征,由于其在训练时,都是通过目标车辆的历史数据进行训练的,因此,对于实时获取的电压偏差下降速度值、绝缘下跌速度值这两个值,基于已经确定的映射关系,可以判断出该目标车辆中的目标电池是否具有恶化趋势。而对于实时获取的静置压差值、绝缘平均水平值、循环平均温度值和循环温升速率值,由于在训练时,是通过同车型、同地区以及同运营模式的车辆的数据进行训练的,因此,对静置压差值、绝缘平均水平值、循环平均温度值和循环温升速率值,基于已经确定的映射关系,可以判断出该目标车辆中的目标电池的分布情况是否异常,即是否与其它车辆存在差异。
进一步地,本实施例中,当基于每个特征对应的取值区间与预警等级之间的映射关系确定了实时获取的每个特征值对应的预警等级后,为了进一步实现预警的准确性,还可以将每个特征值对应的预警等级进行融合,例如对不同的预警等级进行有机组合,以确定出最终的预警等级和处理措施。
示例性地,如图6所示,例如对于每个特征都有三个预警等级,每个特征对应的每个预警等级都可以表达车辆电池的不同信息,具体可参考图6。那么,在进行测试时,每个特征值都会对应预警等级,此时,也可以在电池预警系统401中预设与N个特征值一一对应的N个预警等级中每个预警等级均具有预设映射关系的电池预警信息,然后根据该映射关系确定出最终的预警等级。例如,最终的预警等级也包括三种,分别为一级预警,二级预警和三级预警。当最终的预警等级为三级预警时,可以认为需要高风险紧急处理,当最终的预警等级为二级预警时,可以认为需要功能故障维修处理,而当最终的预警为一级预警时,可以认为影响较小,可以持续观察。
进一步地,当确定了最终的预警等级后,电池预警系统401可以向目标处理设备发送目标处理策略信息和目标安全预警等级信息,其中,目标处理策略信息指示目标处理设备在所述目标安全预警等级信息时执行的操作。
本实施例中,当电池预警系统确定了最终的预警结果时,电池预警系统基于预先制定的故障处理流程,自动下发处理指令动作到目标车辆、充电桩、换电站、用户、车企售后、消防机构,使得各终端和角色在处理同一台车、同一个电池时共享相同的电池信息、预警结果、处理建议,保证处理方法得当、步调一致。
下面,结合图7,说明本申请另一个实施例提供的电池的安全预警方法的流程性示意图。
如图7所示,本实施例的方法可以包括S701、S702、S703和S704。
S701,确定目标车辆电池的目标安全预警等级信息。
其中,有关如何确定目标车辆电池的目标安全预警等级信息的部分可以参考本申请上述实施例中的描述,此处不再赘述。
S702,基于不同的安全预警等级与不同的处理设备对应的处理策略之间的映射关系,确定目标处理策略信息,所述目标处理策略信息指示目标处理设备在目标安全预警等级信息时执行的操作。
示例性地,存储的安全预警等级可以包括已经一级预警、二级预警和三级预警。其中,预警等级程度越高,表示电池越不安全。
示例性地,不同的处理设备例如包括目标车辆、充电桩、换电站和手机。
本实施例中,电池预警系统中存储了安全预警等级与不同的处理设备对应的处理策略之间的映射关系。也就是说,当电池预警系统确定了目标车辆电池的目标安全预警等级信息后,就可以基于存储的不同的安全预警等级与不同的处理设备对应的处理策略之间的映射关系,确定出在目标安全预警等级信息时不同的处理设备对应的处理策略。
作为一种示例,假设安全预警等级与不同的处理设备对应的处理策略之间的映射关系包括:在一级安全预警等级时,目标车辆对应的处理策略为亮故障灯,手机对应的处理策略为通过应用(application,APP)显示故障,在二级安全预警等级时,目标车辆对应的处理策略为亮故障灯与语音提示,手机对应的处理策略为通过APP显示故障并显示处理建议。此时,当确定了目标车辆电池的目标安全预警等级信息为一级预警时,就可以确定目标车辆对应的处理策略为亮故障灯,手机对应的处理策略为通过APP显示故障。
在此说明的是,本实施例中的安全预警等级与不同的处理设备对应的处理策略之间的映射关系仅是一种示例,也可以包括更多的信息,不构成对本申请实施例的限制。
S703,向目标处理设备发送目标处理策略信息和目标安全预警等级信息,相应地,目标处理设备接收目标处理策略信息和目标安全预警等级信息。
本实施例中,在电池预警系统确定了目标安全预警等级信息和目标处理策略信息后,就可以将该目标安全预警等级信息和送目标处理策略信息发送给目标处理设备,相应地,目标处理设备接收目标安全预警等级信息和送目标处理策略信息。
S704,目标处理设备根据目标处理策略信息的指示,在目标车辆电池处于目标安全预警等级信息时执行第一操作。
本实施例中,当目标处理设备接收到目标安全预警等级信息和目标处理策略信息后,就可以基于目标处理策略信息的指示执行相应地操作(即第一操作)。
示例性地,目标处理设备为目标车辆、目标安全预警等级信息为一级预警信息,目标车辆接收到的目标处理策略信息为亮故障灯,此时,目标车辆就可以执行亮故障灯的操作。
示例性地,目标处理设备为手机、目标安全预警等级信息为一级预警信息,目标手机接收到的目标处理策略信息为通过APP显示故障,此时,目标手机就可以执行通过APP显示故障的操作。
本实施例中,目标处理设备可以基于目标处理策略信息的指示,实现对目标车辆电池的处理。也就是说,发送目标处理策略信息和目标安全预警等级信息的设备(电池预警系统)可以将同一个目标车辆电池的信息以及目标处理设备在目标安全预警等级信息时应该如何对目标车辆电池进行处理的信息共享给目标处理设备,从而使得目标处理设备与电池预警系统之间可以实现同一个电池的信息的共享。
作为一个可选实施例,在目标安全预警等级信息为一级预警信息的情况下,电池预警系统可以确定目标处理策略信息包括以下信息:目标车辆亮故障灯。之后,向目 标车辆可以发送该目标处理策略信息,相应地,目标车辆接收该目标处理策略信息,执行亮故障灯的操作。
该实施例中,在目标车辆接收到一级预警信息和目标车辆亮故障灯的目标处理策略信息时,目标车辆执行亮故障灯的操作,从而实现对车辆电池的安全预警。
作为一个可选实施例,在目标安全预警等级信息为一级预警信息和在目标车辆正在通过目标充电桩进行充电的情况下,电池预警系统可以确定目标处理策略信息还包括以下信息:目标充电桩限制对目标车辆电池的充电功率;相应地,在目标车辆正在通过目标充电桩进行充电的情况下,目标充电桩执行限制对目标车辆电池的充电功率的操作。

示例性地,为便于理解,图8所示为最终的预警结果为一级和二级时的处理示意图。如图8所示,当电池预警系统确定了最终的预警结果为一级时,可以提示车辆亮故障灯,并且还可以根据车辆当前的充电状态以及换电状态确定充电桩和换电站的处理建议,例如,当车辆在充电时,电池预警系统可以提示充电桩限制充电功率,当车辆在换电站进行换电时,电池预警系统可以提示换电站限制换电功率。此外,电池预警系统还可以按照一天一次的频率通知车企售后对目标车辆的维修建议,以及通过用户终端中的APP向用户显示故障提示,并发送处理措施建议。
当电池预警系统确定了最终的预警结果为二级时,由于二级预警表示车辆可能发生安全问题,此时可以相比一级预警,处理建议可以幅度更大一些。例如,可以提示车辆亮故障灯的同时还消息提示限制车辆的使用功率,同理,在为二级预警时,还可以根据车辆当前的充电状态以及换电状态确定充电桩和换电站的处理建议,例如,当车辆在充电时,电池预警系统可以提示充电桩限制充电功率以及限制充电上限,当车辆在换电站进行换电时,电池预警系统可以提示换电站限制换电功率以及换电上限并提示启动电池售后流程。此外,电池预警系统实时通知车企售后对车辆的维修建议, 以及通过用户终端中的APP显示故障提示并发送处理措施建议。
示例性地,图9所示为最终预警结果为三级时的处理示意图。如图9所示,当电池预警系统确定了预警结果为三级预警时,此时代表车辆中的电池发生热失控的程度可能已经很严重,此时对于车辆,除了可以提示车辆亮故障灯外可以进一步进行语音告警,此外,还可以根据车辆的行驶状态进行进一步预警提示。例如,当车辆在行驶时,可以限制目标车辆的使用功率,提醒用户安全停车以及提示用户离开车辆,进一步地,若车辆当前的车速为0,可以解锁目标车辆的车门并语音提示用户离开车辆并启动灭火程序。还可以根据车辆当前的充电状态以及换电状态确定充电桩和换电站的处理建议,例如,当车辆即将充电时,电池预警系统可以提示充电桩拒绝充电并语音告知充电桩中的所有用户启动充电站火灾处理流程,当车辆正在充电时,电池预警系统可以提示充电桩停止充电并语音告知充电桩中的所有用户启动充电站火灾处理流程。当车辆在换电站即将进行换电时,电池预警系统可以提示换电站拒绝换电并语音告知换电站中的所有用户启动换电站火灾处理流程。当车辆正在换电时,电池预警系统可以提示充电桩停止换电并语音告知充电桩中的所有用户启动充电站火灾处理流程。此外,电池预警系统还可以实时通知车企售后以及告知车企售后目标车辆的维修建议,以及通过APP进行语音、短信以及消息警告,或者电话呼入提醒用户离开车辆。可以理解的是,当电池预警系统确定了预警等级为三级时,表明车辆中的电池的热失控现象已经很严重,因此,本实施例中,电池预警系统也可以向消防机构发送预警提示信息。例如通过电话呼入报警系统接口同步提示信息到消防机构。
本实施例中,当电池预警系统确定了预警结果时,可以基于电池预警系统基于预先制定的故障处理流程,自动下发处理指令动作到目标车辆、充电桩、换电站、用户、车企售后、消防机构,使得各终端和角色在处理同一台车、同一个电池时共享相同的电池信息、预警结果、处理建议,保证处理方法得当、步调一致。
