In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments These are a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments, and are not intended to limit the present invention.

The embodiment of the present invention provides a method for detecting battery life. The method for detecting battery life can be applied to any electronic device. The electronic device can be a handheld pan/tilt, unmanned aerial vehicle, pan/tilt car, mobile phone, computer, and electric vehicle. , Electric bicycles, etc. The battery life detection method can be executed by a battery provided in the electronic device, and the battery can be provided inside or outside the electronic device.

Take the unmanned aerial vehicle as an example. Figure 1 shows the structure of the unmanned aerial vehicle. As shown in Figure 1, the unmanned aerial vehicle can include a fuselage, a pan-tilt 1 and a camera 2 on the fuselage. . Specifically, the camera 2 can be set on the pan-tilt 1. The camera 2 can be moved relative to the body through the pan/tilt 2. The unmanned aerial vehicle may also include a power system 3. The power system may include an electronic governor, one or more rotors, and one or more motors corresponding to the one or more rotors. Other devices (not shown in the figure) such as an inertial measurement unit may also be provided on the unmanned aerial vehicle, which are not listed here.

Optionally, the unmanned aerial vehicle may also be provided with a first temperature sensor 4 for detecting the ambient temperature of the environment in which the unmanned aerial vehicle is located.

In addition, in order to ensure the normal operation of the unmanned aerial vehicle, the unmanned aerial vehicle also includes a battery 5, through which the battery can provide power support for many devices on the unmanned aerial vehicle.

As shown in FIG. 2, the battery 5 includes a battery core 51 and a battery protection board 52 electrically connected to the battery core 51. Wherein, the number of battery cores 51 may be one or more. One or more processors 53 are provided on the battery protection board 52, and the one or more processors 53 work individually or collectively.

In addition, optionally, as shown in FIG. 2, a second temperature sensor 54 may be provided on the battery protection board 52 to detect the battery temperature. The battery temperature can be understood as the surface temperature of the battery cell. The second temperature sensor 54 may be provided on the surface of the cell 51. The second temperature sensor 54 is electrically connected to the processor 53. The execution process of the battery life detection method will be described in detail below in conjunction with the following embodiments. The battery life detection method provided in the following embodiments may be executed by one or more processors 53 in the embodiment shown in FIG. 2. In addition, when the electronic device described below is used, the battery shown in FIG. 2 is provided in the electronic device for powering the electronic device.

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. 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. 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. Determine the remaining life of the battery according to the battery life consumption value.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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:

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.

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.

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.

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.

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.

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. 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.

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.

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.

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. Determine the correspondence between the use time and the battery life time corresponding to the use temperature.

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.

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. 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.

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).

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.

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.

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.

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.

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.

Wherein, the battery life impact factor corresponding to any battery temperature and ambient temperature of the battery may be the reciprocal of the number of cycles measured at the battery temperature and ambient temperature of the battery.

The description in this embodiment is the case where the battery temperature and the ambient temperature are used as the use temperature at the same time.

Furthermore, the ambient temperature is updated, and the battery temperature is changed at the updated ambient temperature to test the battery life and the number of cycles of use corresponding to different battery temperatures at the updated ambient temperature.

Let's take the following table 3 as an example.

25	25	300	30
45	-10	150	25

Table 3 gives examples of the number of cycles and endurance measured under three different battery temperatures and ambient temperatures.

Based on the indications in Table 3, taking the electronic equipment as an unmanned aerial vehicle as an example, suppose that during a flight of the unmanned aerial vehicle, the ambient temperature experienced successively is 25℃ and -10℃. When the ambient temperature is 25℃, When the ambient temperature is -10°C, the battery temperature is 45°C, and the battery temperature is 25°C for 9 minutes, and the battery temperature is 45°C for 10 minutes, and the remaining battery life is assumed to be 1. After this flight, the remaining life of the battery in the UAV is:
