Detailed Description
In order to make the present application better understood by those skilled in the art, the following description will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. The components of the embodiments of the present application generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the application, as presented in the figures, is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application. All other embodiments, which can be made by a person skilled in the art without making any inventive effort, are intended to be within the scope of the present application.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only to distinguish the description, and are not to be construed as indicating or implying relative importance.
And a battery, which converts the chemical energy stored in the battery into electric energy. The battery has the characteristics of stable voltage, stable current, long-time stable power supply and the like, plays an important role in various aspects of life in modern society, and occupies a large proportion in the use of electric energy. Batteries can be classified into those according to their operational properties and storage modes: primary batteries such as zinc-manganese dry batteries and the like; secondary batteries such as nickel-metal hydride batteries and the like; fuel cells such as hydrogen-oxygen fuel cells and the like; storage cells, such as silver-magnesium cells, and the like. The secondary battery is a battery which can be repeatedly used for a plurality of times, and has wide application due to the advantages of being capable of being repeatedly used, accords with the economical and practical principle. Currently, lead-acid batteries are stably taken up in the secondary battery market.
For lead-acid batteries, the discharge working voltage is stable, the lead-acid batteries can be discharged with small current or large current, the working temperature range is wide, the battery technology is mature, the cost is low, and the following load output characteristic is good, so that the lead-acid batteries are not lost as important products in storage batteries. However, this battery has significant disadvantages such as a large weight and a low specific energy by mass, while the LA battery has a theoretical specific energy of 240Wh/kg, actually only (10 to 50) Wh/kg, and a slow charging speed. And lead-acid batteries can age under long-term shelf, overcharging, overdischarge, etc., affecting the use of equipment powered by such batteries. Specifically, taking the storage battery car as an example, most vehicles are parked outdoors for a long time, and the user maintenance behaviors are less, the vehicle battery is easy to age, the aged vehicles are easy to start and flameout, and the like, so that the current travel plan of the user is greatly influenced, and meanwhile, the user is easy to correlate the influence with the brand of the vehicle, so that the public praise of the brand is influenced. Therefore, it is necessary to detect the aging state of the battery, and it is important to take measures before it has a large influence.
Further, it is not enough to detect the aging degree, and more accurate detection is required, and when the detected aging degree does not coincide with the actual situation of the battery, a misjudgment or a situation that the battery has aged and failed but is not early-warned in time may occur. When misjudgment occurs, the battery is not aged and no countermeasures are needed, but corresponding countermeasures are taken due to misjudgment, so that the burden of a user is increased, and meanwhile, energy waste is caused; when the aged battery fails and early warning cannot be performed in time, particularly, the requirement of important applications such as telecommunication power and the like on the battery is very high, the battery must be replaced as long as the capacity is lower than a certain index, and the high-efficiency safe operation of a power system can be influenced once the detection early warning is not performed in time, so that the problem to be solved when the aged state of the battery is detected is not solved at all, and the problem is not different from the problem when the aged state is not detected. Therefore, a more accurate battery aging state detection method is required.
Currently, the battery aging degree is detected by calculating the voltage of the battery when the battery is powered to detect the aging state of the battery, and by monitoring the voltage of the battery when the battery is powered, the aging degree of the battery is detected from the current voltage state of the battery.
However, the inventors found in the study that the detection of the aging degree of the battery according to the current voltage state of the battery is not accurate enough. Firstly, the voltage is unstable when the battery is powered, the numerical value is larger, secondly, the calculation precision of the battery voltage is integer digital, the precision is lower, so that the aging detection of the battery is not consistent with the actual situation, the error is larger, and the situation that misjudgment or the aging fault of the battery is not early-warned in time can occur.
Therefore, in order to overcome the above-mentioned drawbacks, the embodiments of the present application provide a battery aging detection method, apparatus, electronic device, and computer readable storage medium, which are based on the characteristics that the charging duration of the target battery charging target percentage power of different remaining available capacities is stable, and the aging degree of the target battery can be accurately reflected, and by comparing the charging durations of the battery to be detected and the target battery charging target percentage power, the accuracy of determining the aging analysis result of the battery to be detected according to the comparison result is higher.
Referring to fig. 1, fig. 1 shows a flowchart of a battery aging detection method according to an embodiment of the present application, for an electronic device, where the method includes:
S101, acquiring a plurality of preset durations corresponding to a plurality of target batteries, wherein each preset duration refers to a charging duration of charging a target battery corresponding to the preset duration by a target percentage of electric quantity, and the residual available capacities of the target batteries corresponding to different preset durations are different.
It should be noted that the available capacity refers to a capacity that can be actually released during a use process of the battery, and in the actual use process, the available capacity is smaller than a maximum capacity of the battery due to an internal resistance of the battery, so that the battery can reach a discharge termination voltage earlier when discharging. The remaining usable capacity refers to the usable capacity actually remaining after the battery is used for a certain period of time, and the remaining usable capacity of the new battery is the same as the usable capacity.
As an implementation manner, the plurality of target batteries may be the same type batteries, specifically, 100% full charge test is performed on all the target batteries, at least charge current and charge amount data are collected and recorded in the whole test process, a charging model of the batteries is built, residual available capacities corresponding to the plurality of target batteries are obtained, and preset time lengths corresponding to the target batteries with different residual available capacities are obtained based on the battery charging model.
The aging state of the battery represents the durability of the battery, the remaining available capacity of the battery can intuitively represent the durability of the battery, and a plurality of preset time durations obtained based on the charging model are theoretically only related to the remaining available capacity of the battery, so that the preset time durations can reflect the durability of the battery, namely the aging state of the battery, one preset time duration can represent the limit of the primary aging state, specifically, the charging time duration is smaller than the preset time duration to be an aging state, the charging time duration is greater than or equal to the preset time duration to be an aging state, and the aging analysis result of the battery to be detected can be more accurately determined through the preset time duration setting.
As an implementation manner, the target percentage Of electricity may be a specified percentage Of electricity, and the remaining amount Of electricity (SOC) refers to a proportion Of the available electricity in the battery to the nominal capacity, which is generally expressed as a percentage, and the target percentage may be 1%, or may be selected according to the requirement, which is not described herein in detail. Because the batteries of the same type have certain tolerance in design, production and assembly, although the marking parameters on the batteries of the same type are the same, the tolerance can lead to different actual parameters, so that the charging time lengths of a plurality of target batteries with the same residual available capacity can be the same or different, and the charging time lengths of the target batteries with the same residual available capacity are called as test preset time lengths. If all the preset time lengths of the tests with the same residual available capacity are used as the preset time lengths corresponding to the residual available capacity, the results obtained later lack consistency, so that a characteristic value capable of representing all the preset time lengths of the tests needs to be selected as the preset time length under the current residual available capacity.
In some embodiments, processing all the obtained data of different testing preset time lengths with the same residual available capacity, wherein the preset time lengths can be the average number of the data, so that the obtained preset time lengths are related to the testing preset time lengths of the target batteries with the same residual available capacity, and the actual conditions of all the target batteries are fully considered; the preset duration can be the median of the test preset duration data, and the median can just reflect the centralized trend of all the test preset durations of the same residual available capacity target battery; the preset time length can be the mode of the test preset time length data, when a plurality of times of repeated data exist in the data, the mode of the data can often represent the whole data, and further, the value of the preset time length can be set according to the actual use requirement. That is, the preset time period can represent the overall level of the target battery charging target percentage charge time period of the same remaining available capacity, and further, the preset time periods corresponding to different target batteries of the same remaining available capacity are the same.
S102, acquiring target charging duration of the battery to be detected, wherein the target charging duration refers to charging duration of a target percentage of electric quantity of the battery to be detected.
As an implementation manner, the battery to be detected is a battery matched with the target battery, the matching of the battery to be detected and the target battery may mean that the battery to be detected and the target battery may be the same type battery, the rated capacity of the battery to be detected and the rated capacity of the target battery are the same, the remaining available capacity of the battery to be detected may be the same as the remaining available capacity of the target battery, the remaining available capacity of the battery to be detected may also be different from the remaining available capacity of the target battery, the charging conditions of the battery to be detected and the target battery are the same, and the charging duration of the charging target percentage electric quantity is the same. The target charging duration refers to the charging duration of the battery to be detected for charging the target percentage of electric quantity, and the target charging duration can reflect the current aging state of the battery to be detected.
S103, determining a comparison result of the target charging duration and a plurality of preset durations;
S104, determining an aging analysis result of the battery to be detected according to the comparison result.
As an embodiment, the target battery and the battery to be detected may be lithium batteries, the target battery and the battery to be detected may be lead-acid storage batteries, and the target battery and the battery to be detected may be the same type of battery.
From the foregoing, it can be seen that the preset duration can reflect the aging state of the target battery, the target charging duration can reflect the current aging state of the battery to be detected, and by setting the preset duration and comparing the target charging duration with the preset duration, the aging analysis result of the battery to be detected can be determined according to the grade limit of the aging state represented by the preset duration, so that the problems of large error of data reading and inaccurate prediction caused by unstable electrochemical devices of the battery are avoided, and the accuracy of battery aging detection is improved.
Taking a vehicle as an example, the accuracy of battery aging prediction is improved, vehicle faults of users are reduced to a certain extent, complaints of users are reduced, the public praise of vehicle quality is guaranteed, meanwhile, battery aging data are provided for automatic power supply, load management and the like of the whole vehicle low-voltage energy management module, functions of the whole vehicle low-voltage energy management module can be optimized, battery use and maintenance reminding is carried out, battery aging is slowed down, and the use cost performance of the storage battery is improved.
In this embodiment, the durability of the battery is represented based on the aging state of the battery, and the remaining available capacity of the battery can intuitively represent the durability of the battery, so that the charging duration of the target battery charging target percentage capacity of different remaining available capacities is stable, thereby accurately reflecting the aging degree of the target battery, and according to the charging duration of the battery charging target percentage capacity to be detected and the charging duration of each target battery, the determined comparison result can accurately reflect the relationship between the battery to be detected and the target battery, and further, the accuracy of the aging analysis result of the battery to be detected is higher.
In addition, the charging current and the charging time length also have influence, and the larger the charging current of the battery is, the smaller the charging time length is. The larger the charge current of the battery, the thicker the chemical crystal particles generated on the electrode plate, and the lower the ability to store and discharge. Because the coarser the chemical crystal particles generated, the smaller the surface area of the participating discharge crystals, and the greater the internal resistance of the battery. The storage and discharge capacity of the battery is represented by the available capacity of the battery, and the measured battery charging time at a large current is inaccurate to indicate the storage and discharge capacity of the battery, so that the influence of the charging current on the detection of the aging state of the battery needs to be overcome.
Referring to fig. 2, fig. 2 shows a flowchart of a battery aging detection method according to another embodiment of the present application, for an electronic device, where the method includes:
s201, acquiring a plurality of preset durations corresponding to a plurality of target batteries, wherein each preset duration refers to a charging duration of charging a target battery corresponding to the preset duration by a target percentage of electric quantity, and the residual available capacities of the target batteries corresponding to different preset durations are different.
The description of S201 refers to the description of S101 above, and is not repeated here.
S202, charging a battery to be detected, and monitoring the charging current of the battery to be detected;
And S203, when the charging current of the battery to be detected is smaller than the target current, acquiring the charging duration of the charging target percentage electric quantity of the battery to be detected as the target charging duration.
As an implementation manner, before the target charging time length of the battery to be detected is obtained, the charging current is monitored, and when the charging current of the battery to be detected is monitored to be smaller than the target current, the charging time length at the moment is obtained as the target charging time length, and the aging state of the battery to be detected at the moment is more accurate according to the target charging time length. In some embodiments, the target current may be 0.5A, and a charging duration for charging the battery to be detected by a target percentage charge with a charging current less than 0.5A is used as the target charging duration.
S204, determining a comparison result of the target charging duration and a plurality of preset durations.
S205, determining an aging analysis result of the battery to be detected according to the comparison result.
The descriptions of S204-S205 refer to the descriptions of S103-S104 above, and are not repeated here.
In this embodiment, a target current is set, and when the charging current is less than the target current, the charging duration of the battery to be detected at this time is obtained as the target charging duration, at this time, the electrochemical reaction inside the battery is relatively stable, the internal resistance is relatively stable, and the obtained charging duration is used to represent the internal available capacity of the battery to be detected, so that the aging state of the battery to be detected is relatively accurate.
Referring to fig. 3, fig. 3 shows a flowchart of a battery aging detection method according to still another embodiment of the present application, for an electronic device, the method includes:
s301, obtaining a plurality of target batteries corresponding to the residual available capacities respectively; charging each target battery and monitoring the charging current of each target battery; and when the charging current of the target battery is smaller than the target current, acquiring the charging duration of the target battery for charging the target percentage electric quantity as the preset duration of the corresponding target battery.
In this embodiment, a plurality of target batteries corresponding to the remaining available capacities are obtained first, charging current is monitored before the charging time of the target battery corresponding to the remaining available capacities is obtained, the charging time at the moment is obtained as a preset time when the charging current of the target battery is monitored to be smaller than the target current, the preset time is used as a limit of a primary aging state, and the target charging time is compared with the preset time to show that the aging state of the battery to be detected at the moment is more accurate.
For different preset test durations of the target battery with the same remaining available capacity, the data processing method may refer to the foregoing embodiment, and will not be described herein again, and the value of the target current may refer to the foregoing embodiment, and will not be described again.
Furthermore, considering that one remaining available capacity corresponds to one preset time length, judging the aging state of the battery to be detected only needs to select the preset time length corresponding to the state dividing limit, and all preset time lengths do not need to be considered.
As one embodiment, the method for determining each target battery may include: acquiring preset batteries corresponding to different use time lengths respectively, wherein the preset batteries are matched with the battery to be detected; obtaining the residual available capacity of each preset battery; and acquiring a preset battery with the residual available capacity being the preset residual available capacity as a target battery.
As an implementation manner, the matching of the preset battery and the battery to be detected may mean that the preset battery and the battery to be detected may be the same type battery, and the rated capacities of the preset battery and the battery to be detected are the same. The aging state of the battery to be detected is judged by only selecting the preset time length corresponding to the state dividing limit, namely only selecting the preset battery with the residual available capacity corresponding to the preset time length as the preset residual available capacity as the target battery. For example, the preset remaining usable capacity may be 70%, 50%, 30% of the rated capacity of the preset battery, and the like.
The different use time periods may refer to 1 year, 3 years, 5 years, etc., the preset batteries corresponding to the different use time periods are obtained, the obtained remaining available capacities of the preset batteries are counted, and the preset battery with the remaining available capacity being the preset remaining available capacity is determined as the target battery.
Illustratively, for example, the remaining available capacity is 70% of the rated capacity of the preset battery, the battery 1 whose remaining available capacity is 70% of the rated capacity, the battery 2 whose rated capacity is 80% of the rated capacity, and the battery 3 whose rated capacity is 65% of the rated capacity are acquired, and the battery 1 is determined as the target battery.
S302, acquiring target charging duration of the battery to be detected, wherein the target charging duration refers to charging duration of a target percentage of electric quantity of the battery to be detected.
S303, determining a comparison result of the target charging duration and a plurality of preset durations.
