图3为本发明实施例提供的一种电池寿命检测方法的流程示意图,如图3所示,该方法可以包括如下步骤:FIG. 3 is a schematic flowchart of a method for detecting battery life according to an embodiment of the present invention. As shown in FIG. 3, the method may include the following steps:
301、获取电子设备最近一次被使用时对应的使用时间和使用温度,其中,使用温度包括如下至少一种:电池温度、环境温度。301. Obtain the use time and use temperature corresponding to the last time the electronic device was used, where the use temperature includes at least one of the following: battery temperature and ambient temperature.
302、根据使用时间和使用温度确定电子设备最近一次被使用时对应的电池寿命消耗值。302. Determine the battery life consumption value corresponding to the last time the electronic device was used according to the use time and the use temperature.
303、根据电池寿命消耗值确定电池的剩余寿命。303. Determine the remaining life of the battery according to the battery life consumption value.
其中,可以理解的是,上述环境温度可以是通过图1所示实施例中的第一温度传感器采集的,上述电池温度可以是通过图2所示实施例中的第二温度传 感器采集的。It can be understood that the above-mentioned ambient temperature may be collected by the first temperature sensor in the embodiment shown in FIG. 1, and the above-mentioned battery temperature may be collected by the second temperature sensor in the embodiment shown in FIG. 2.
相对于当前想要使用电子设备的时刻,电子设备最近一次被使用的情形是指上一次使用电子设备的时候。Compared with the current time when the electronic device is intended to be used, the last time the electronic device was used refers to the last time the electronic device was used.
从而,对于使用时间来说,自上一次电子设备被上电开机开始到断电关机为止所经历的时间即可以认为是上一次电子设备被使用时所对应的使用时间。可以理解的是,电子设备在每次被使用的过程中,自上电开机开始,可以触发一个计时器开始计时,直到本次使用结束,被断电关机为止,从而可以获得本次使用电子设备的使用时间。Therefore, for the use time, the elapsed time from the last time the electronic device was powered on to the power off and turned off can be regarded as the use time corresponding to the last time the electronic device was used. It is understandable that every time the electronic device is used, a timer can be triggered to start counting from the power-on and start-up, until the end of this use and the power is turned off, so that the electronic device used this time can be obtained. Time of use.
对于使用温度来说,可选地,获取电子设备最近一次被使用时对应的使用温度,可以实现为:获取电子设备最近一次被使用时与起始使用时刻对应的使用温度。也就是说,每当电子设备被开机以触发工作时,通过第一温度传感器和/或第二温度传感器采集当前时刻的环境温度和/或电池温度,作为本次电子设备被使用时所对应的使用温度。确定本次电子设备被使用时所对应的使用温度的方式可以有多种。可选的,当环境温度与电池温度差异较大时,电池比较容易达到环境温度,取环境温度作为使用温度。可选的,当环境温度与电池温度差异不大时,取电池温度作为使用温度。可选的,同时获取环境温度、电池温度,根据环境温度、电池温度共同确定使用温度。For the use temperature, optionally, obtaining the use temperature corresponding to the last time the electronic device was used may be implemented as: obtaining the use temperature corresponding to the initial use time when the electronic device was last used. That is to say, whenever the electronic device is turned on to trigger work, the current ambient temperature and/or battery temperature are collected through the first temperature sensor and/or the second temperature sensor, as the corresponding value when the electronic device is used. Operating temperature. There are many ways to determine the corresponding use temperature when the electronic device is used. Optionally, when the ambient temperature and the battery temperature are significantly different, the battery is easier to reach the ambient temperature, and the ambient temperature is taken as the use temperature. Optionally, when the ambient temperature is not much different from the battery temperature, the battery temperature is taken as the use temperature. Optionally, obtain the ambient temperature and battery temperature at the same time, and determine the use temperature according to the ambient temperature and battery temperature.
可选地,获取电子设备最近一次被使用时的使用时间和使用温度,还可以实现为:获取电子设备最近一次被使用时与不同时刻对应的使用温度,根据不同时刻对应的使用温度确定至少一个目标使用温度以及至少一个目标使用温度对应的使用时间。在该方式中,并非以上次电子设备被使用时的起始时刻对应的电池温度和/或环境温度作为电子设备最近一次被使用时对应的使用温度,而是考虑整个使用过程中的温度变化情况。考虑整个使用过程中温度也可能发生变化,这样可以得到更精确地寿命估计结果。Optionally, obtaining the use time and use temperature of the electronic device when the electronic device was last used can also be implemented as: obtaining the use temperature corresponding to different moments when the electronic device was last used, and determining at least one of the use temperatures corresponding to the different moments. The target use temperature and the use time corresponding to at least one target use temperature. In this method, the battery temperature and/or ambient temperature corresponding to the initial time when the electronic device was used last time is not used as the corresponding use temperature when the electronic device was last used, but the temperature change during the entire use process is considered. . Consider that the temperature may also change during the entire use process, so that a more accurate life expectancy can be obtained.
为便于描述,结合图4来示例性说明。其中,图4中是以电池温度为例来进行说明,环境温度同理。在图4中,假设电子设备最近一次被使用时的使用时间由起始时刻T1和结束时刻T2界定。在电子设备被使用过程中,通过温度 传感器以设定的采样频率对电池温度进行采集,得到不同时刻对应的电池温度。根据不同时刻对应的电池温度的变化情况,可以将T1至T2的时间划分为一个或多个时间段,每个时间段对应于一个电池温度值,不同时间段对应的电池温度值之间的差值大于设定阈值。比如图4中示意的划分为三个时间段:t1、t2和t3,这三个时间段对应的电池温度值分别为C1、C2和C3。此时,这三个电池温度值将作为电子设备最近一次被使用时对应的至少一个目标使用温度。For ease of description, an exemplary description is given in conjunction with FIG. 4. Among them, the battery temperature is taken as an example in FIG. 4 for illustration, and the ambient temperature is the same. In FIG. 4, it is assumed that the use time of the last time the electronic device was used is defined by the start time T1 and the end time T2. When the electronic device is in use, the battery temperature is collected by the temperature sensor at a set sampling frequency to obtain the battery temperature at different times. According to the change of the battery temperature at different times, the time from T1 to T2 can be divided into one or more time periods, each time period corresponds to a battery temperature value, and the difference between the battery temperature values corresponding to different time periods The value is greater than the set threshold. For example, Figure 4 is schematically divided into three time periods: t1, t2, and t3. The battery temperature values corresponding to these three time periods are C1, C2, and C3, respectively. At this time, the three battery temperature values will serve as at least one target use temperature corresponding to the last time the electronic device was used.
基于此,根据使用时间和使用温度确定电子设备最近一次被使用时对应的电池寿命消耗值,将实现为:根据该至少一个目标使用温度以及至少一个目标使用温度对应的使用时间,确定该至少一个目标使用温度各自对应的电池寿命消耗值,从而,最终累加该至少一个目标使用温度各自对应的电池寿命消耗值,以得到电子设备最近一次被使用时对应的电池寿命消耗值。Based on this, determining the battery life consumption value corresponding to the last time the electronic device was used according to the use time and use temperature will be realized as: determining the at least one target use temperature and the use time corresponding to the at least one target use temperature The battery life consumption value corresponding to each target use temperature, so that the battery life consumption value corresponding to the at least one target use temperature is finally accumulated to obtain the battery life consumption value corresponding to the last time the electronic device was used.
电子设备每次被使用时所对应的使用时间和使用温度会存储下来,以便下一次使用电子设备时能够读取获得电子设备最近一次被使用时所对应的使用时间和使用温度。例如,可以将电子设备每次被使用时所对应的使用时间和使用温度存储在一存储单元中,该电子设备每次被使用时所对应的使用时间和使用温度可以被读取,以便用在寿命估计和/或异常检测等场景。The usage time and usage temperature corresponding to each time the electronic device is used are stored, so that the next time the electronic device is used, the usage time and usage temperature corresponding to the last time the electronic device is used can be read. For example, the use time and use temperature corresponding to each time the electronic device is used can be stored in a storage unit, and the use time and use temperature corresponding to each time the electronic device is used can be read for use in Scenarios such as life estimation and/or anomaly detection.
以该电子设备为无人飞行器为例,假设当前时刻想要使用无人飞行器执行某种飞行任务,那么无人飞行器最近一次被使用即为上一次控制无人飞行器飞行的时候。从而,上一次无人飞行器的飞行时间即为无人飞行器最近一次被使用时所对应的使用时间。可选地,上一次无人飞行器起飞时刻所对应的环境温度和/或电池温度即为无人飞行器最近一次被使用时所对应的使用温度。无人飞行器每一次飞行时,电池的使用温度可能不同,甚至差距很大,因此,按照每次飞行记录使用时间以及使用温度,可以准确的进行寿命估计。Taking the electronic device as an unmanned aerial vehicle as an example, if you want to use the unmanned aerial vehicle to perform a certain flight task at the current moment, the last time the unmanned aerial vehicle was used is the last time the unmanned aerial vehicle was controlled to fly. Therefore, the last flight time of the unmanned aerial vehicle is the use time corresponding to the last time the unmanned aerial vehicle was used. Optionally, the ambient temperature and/or battery temperature corresponding to the last take-off time of the unmanned aerial vehicle is the operating temperature corresponding to the last time the unmanned aerial vehicle was used. Every time an unmanned aerial vehicle flies, the temperature of the battery may be different, or even vary greatly. Therefore, according to the recorded use time and temperature of each flight, the life expectancy can be accurately estimated.
综上,不管是以哪种方式获得的电子设备最近一次被使用时对应的使用时间和使用温度,在使用温度包含环境温度和/或电池温度的情况下,步骤302中根据使用时间和使用温度确定电子设备最近一次被使用时对应的电池寿命 消耗值的实现方式可以包括如下两种可选方式:In summary, no matter which method is used to obtain the corresponding use time and use temperature of the electronic device when it was last used, if the use temperature includes the ambient temperature and/or the battery temperature, step 302 is based on the use time and use temperature. The method for determining the battery life consumption value corresponding to the last time the electronic device was used may include the following two optional methods:
在一种可选方式中,根据电子设备最近一次被使用时对应的使用时间和使用温度确定电子设备最近一次被使用时对应的电池寿命消耗值,可以实现为:若电池温度以及环境温度满足预设条件,则根据使用时间和电池温度确定电子设备最近一次被使用时对应的电池寿命消耗值;否则,根据使用时间和环境温度确定电子设备最近一次被使用时对应的电池寿命消耗值。In an optional manner, the battery life consumption value corresponding to the last use of the electronic device is determined according to the use time and use temperature of the last use of the electronic device, which can be implemented as follows: if the battery temperature and the ambient temperature meet the expected If the conditions are set, the battery life consumption value corresponding to the last use of the electronic device is determined according to the use time and battery temperature; otherwise, the battery life consumption value corresponding to the last use of the electronic device is determined according to the use time and ambient temperature.
在该方式中,电池温度和环境温度只使用一种。上述预设条件可以包括:电池温度与环境温度的差值满足参考阈值范围。比如,当电池温度与环境温度的差值大于设定阈值时,只用环境温度或电池温度,反之,如果电池温度与环境温度的差值小于设定阈值,则只用电池温度。In this method, only one of battery temperature and ambient temperature is used. The foregoing preset condition may include: the difference between the battery temperature and the ambient temperature satisfies the reference threshold range. For example, when the difference between the battery temperature and the ambient temperature is greater than the set threshold, only the ambient temperature or battery temperature is used. Conversely, if the difference between the battery temperature and the ambient temperature is less than the set threshold, only the battery temperature is used.
值得说明的是,当基于上文的介绍确定出的使用温度包括多种环境温度与多种电池温度时,可选地,可以求取多种环境温度的平均值以及多种电池温度的平均值,这两个平均值的差值如果大于设定阈值,则确定采用多种电池温度进行电池寿命消耗值的计算,反之,确定采用多种环境温度进行电池寿命消耗值的计算。It is worth noting that when the operating temperature determined based on the above introduction includes multiple ambient temperatures and multiple battery temperatures, optionally, the average value of multiple ambient temperatures and the average value of multiple battery temperatures can be obtained. If the difference between the two average values is greater than the set threshold, it is determined that multiple battery temperatures are used to calculate the battery life consumption value, otherwise, it is determined that multiple environmental temperatures are used to calculate the battery life consumption value.
在另一种可选方式中,根据电子设备最近一次被使用时对应的使用时间和使用温度确定电子设备最近一次被使用时对应的电池寿命消耗值,可以实现为:根据该使用时间、电池温度和环境温度确定电子设备最近一次被使用时对应的电池寿命消耗值。在该方式中,电池温度和环境温度均被使用。In another optional manner, the battery life consumption value corresponding to the last time the electronic device was used is determined according to the corresponding use time and use temperature when the electronic device was last used, which can be implemented as follows: according to the use time and battery temperature And the ambient temperature determine the battery life consumption value corresponding to the last time the electronic device was used. In this way, both the battery temperature and the ambient temperature are used.
综上,不管确定电子设备最近一次被使用时对应的电池寿命消耗值时所采用的使用温度是上述提及的哪种,概括来说,步骤302中根据使用时间和使用温度确定电子设备最近一次被使用时对应的电池寿命消耗值的具体实现过程可以参见图5来实现。In summary, no matter which of the above-mentioned use temperatures are used to determine the battery life consumption value corresponding to the last time the electronic device was used, in a nutshell, in step 302, the last time the electronic device is used is determined according to the use time and use temperature. The specific realization process of the corresponding battery life consumption value when being used can be realized by referring to FIG. 5.
图5为本发明实施例提供的一种确定电子设备最近一次被使用时对应的电池寿命消耗值的流程示意图,如图5所示,可以包括如下步骤:FIG. 5 is a schematic flowchart of determining the battery life consumption value corresponding to the last time an electronic device was used according to an embodiment of the present invention. As shown in FIG. 5, it may include the following steps:
501、确定与使用温度对应的电池寿命影响因子,电池寿命影响因子对应电池完成一次充放电周期所损失的寿命。501. Determine the battery life impact factor corresponding to the use temperature, and the battery life impact factor corresponds to the life lost by the battery after completing a charge and discharge cycle.
本发明实施例中,不同使用温度会对应于不同的电池寿命影响因子,由电池寿命影响因子的上述含义可知,这就意味着不同使用温度下,电池完成一次充放电周期所损失的寿命是不同的。In the embodiment of the present invention, different use temperatures correspond to different battery life influencing factors. From the above meaning of the battery life influencing factors, this means that the battery life lost by completing a charge and discharge cycle is different at different use temperatures. of.
举例来说,假设在第一使用温度下,电池的循环使用次数为N次,意味着电池的使用寿命对应于N次充点电周期,从而,可选地,该第一使用温度对应的电池寿命影响因子可以设定为:1/N。同理,假设在第二使用温度下,电池的循环使用次数为M次,从而,该第二使用温度对应的电池寿命影响因子可以设定为:1/M。For example, assuming that the number of cycles of use of the battery is N times at the first use temperature, it means that the service life of the battery corresponds to N charging cycles, so that, optionally, the battery corresponding to the first use temperature The life impact factor can be set as: 1/N. In the same way, it is assumed that at the second use temperature, the number of cycles of use of the battery is M times, and thus, the battery life impact factor corresponding to the second use temperature can be set as: 1/M.
实际应用中,可以预先测定各种使用温度对应的电池寿命影响因子,以便基于此查询确定不同使用温度对应的电池寿命影响因子。In practical applications, the battery life impact factors corresponding to various use temperatures can be determined in advance, so as to determine the battery life impact factors corresponding to different use temperatures based on this query.
502、确定使用时间与使用温度对应的电池续航时间的对应关系。502. Determine the correspondence between the use time and the battery life time corresponding to the use temperature.
本发明实施例中,除了需要测定不同使用温度对应的电池寿命影响因子外,还需要测定不同使用温度对应的电池续航时间。不同使用温度下,电池续航时间是不同的。其中,电池续航时间可以简单地理解为电池从满电到没电所需要的时长。In the embodiment of the present invention, in addition to determining the battery life impact factors corresponding to different use temperatures, it is also necessary to determine the battery life time corresponding to different use temperatures. Under different operating temperatures, battery life is different. Among them, the battery life can be simply understood as the length of time it takes for the battery to go from fully charged to dead.
上述使用时间与某使用温度下的电池续航时间的对应关系比如为:使用时间与该使用温度对应的电池续航时间的比值。假设电子设备最近一次被使用时对应的使用时间为20分钟,上述第一使用温度下对应的电池续航时间为60分钟,则使用时间与该电池续航时间的比值为:1/3。The corresponding relationship between the use time and the battery life time at a certain use temperature is, for example, the ratio of the use time to the battery life time corresponding to the use temperature. Assuming that the last time the electronic device was used, the corresponding use time was 20 minutes, and the corresponding battery life time at the first use temperature was 60 minutes, and the ratio of the use time to the battery life time was 1/3.
503、根据电池寿命影响因子和所述对应关系确定电子设备最近一次被使用时对应的电池寿命消耗值。503. Determine a corresponding battery life consumption value when the electronic device was last used according to the battery life impact factor and the corresponding relationship.
当使用时间与使用温度对应的电池续航时间的对应关系实现为使用时间与使用温度对应的电池续航时间之间的比值时,在上述举例的第一使用温度下,电子设备最近一次被使用时对应的电池寿命消耗值可以是:上述电池寿命影响因子和该比值的乘积,即(1/N)*(1/3)。When the corresponding relationship between the use time and the battery life time corresponding to the use temperature is realized as the ratio between the use time and the battery life time corresponding to the use temperature, at the first use temperature in the above example, the electronic device corresponds to the last time it was used The battery life consumption value of can be: the product of the above-mentioned battery life impact factor and the ratio, that is, (1/N)*(1/3).
综上,在根据电子设备最近一次被使用时对应的使用时间和使用温度确定电子设备最近一次被使用时对应的电池寿命消耗值之后,可以根据该电池 寿命消耗值确定电池的剩余寿命。In summary, after determining the battery life consumption value corresponding to the last time the electronic device was used according to the corresponding use time and temperature when the electronic device was last used, the remaining battery life can be determined according to the battery life consumption value.
具体来说,可以将电池并未被使用(从未被使用)时的电池寿命归一化表示为1,每使用一次电子设备后,更新电池的剩余寿命。以电子设备最近一次被使用时为例,更新方式为:在电子设备最近一次被使用时之前,电池的剩余寿命的基础上减去电子设备最近一次被使用时所导致的电池寿命消耗值。举例来说,假设上次使用电子设备之前,电池的剩余寿命为0.9,上次使用电子设备导致的电池寿命消耗值为0.2,则本次使用电子设备前,电池的剩余寿命为:0.9-0.2=0.7。Specifically, the battery life when the battery is not used (never used) can be normalized as 1, and the remaining life of the battery is updated every time the electronic device is used. Taking the time when the electronic device was last used as an example, the update method is: before the last time the electronic device was used, the remaining battery life is subtracted from the battery life consumption value caused by the last time the electronic device was used. For example, suppose that before the last use of the electronic device, the remaining life of the battery is 0.9, and the battery life consumption value caused by the last use of the electronic device is 0.2, then the remaining life of the battery before using the electronic device this time is: 0.9-0.2 = 0.7.
基于此,在本次使用电子设备前,如果确定电池的剩余寿命低于设定阈值,则输出告警信息,以便提示用户当前该电子设备的使用寿命不足,以便用户做出更换电池等响应处理,保证电子设备的正常使用。实际应用中,该阈值可以是0或大于0的数值。Based on this, before the electronic device is used this time, if it is determined that the remaining battery life is lower than the set threshold, an alarm message will be output to remind the user that the current electronic device has insufficient service life, so that the user can make a response such as replacing the battery. Ensure the normal use of electronic equipment. In practical applications, the threshold can be zero or a value greater than zero.
综上,通过考虑使用时间和使用温度对电池寿命的影响,可以使得电池寿命的确定结果更加准确,能够真实地反映出电池的实际剩余寿命。In summary, by considering the influence of the use time and the use temperature on the battery life, the determination result of the battery life can be made more accurate, which can truly reflect the actual remaining life of the battery.
在上述实施例中提到,需要预先确定不同使用温度对应的电池寿命影响因子,下面结合图6和图7所示实施例介绍两种确定电池寿命影响因子的方式。It is mentioned in the above embodiment that it is necessary to predetermine the battery life impact factors corresponding to different use temperatures. The following describes two ways of determining the battery life impact factors in conjunction with the embodiments shown in FIG. 6 and FIG. 7.
图6为本发明实施例提供的一种确定不同使用温度对应的电池寿命影响因子的流程示意图,如图6所示,可以包括如下步骤:FIG. 6 is a schematic diagram of a process for determining battery life impact factors corresponding to different use temperatures according to an embodiment of the present invention. As shown in FIG. 6, it may include the following steps:
601、确定电池在多种使用温度下各自对应的续航时间和循环使用次数,其中,使用温度包括电池温度或环境温度。601. Determine the battery life and the number of cycles of use corresponding to each of the batteries at multiple use temperatures, where the use temperature includes the battery temperature or the ambient temperature.
602、根据电池在多种使用温度下各自对应的循环使用次数,确定电池在多种使用温度下各自对应的电池寿命影响因子。602. Determine the respective battery life impact factors corresponding to the battery at the multiple use temperatures according to the number of cycles of use of the battery at the multiple use temperatures.
本实施例中说明的是使用温度采用电池温度和环境温度中的一种的情况。The description in this embodiment is a case where the use temperature adopts one of the battery temperature and the ambient temperature.
当采用电池温度时,测量在不同电池温度下电池分别对应的续航时间和循环使用次数。此时,电池在不同电池温度下各自对应的电池寿命影响因子可以是在不同电池温度下各自测得的循环使用次数的倒数。When the battery temperature is used, the battery life time and the number of cycles of use corresponding to the battery under different battery temperatures are measured. At this time, the respective battery life impact factors corresponding to the batteries at different battery temperatures may be the reciprocal of the number of cycles of use respectively measured at different battery temperatures.
当采用环境温度时,测量在不同环境温度下电池分别对应的续航时间和 循环使用次数。此时,电池在不同环境温度下各自对应的电池寿命影响因子可以是在不同环境温度下各自测得的循环使用次数的倒数。When using the ambient temperature, measure the battery life and cycle times corresponding to different ambient temperatures. At this time, the respective battery life impact factors corresponding to the batteries at different ambient temperatures may be the inverse of the number of cycles of use respectively measured at different ambient temperatures.
下面结合如下表1和表2举例来说。Let's take the following table 1 and table 2 as examples.
