Compared with the method that whether the charging current is reduced to the fixed charging cut-off current is used as the basis for judging whether to stop charging or not, when the charging capacity is larger than or equal to the set capacity, whether the charging capacity increment in the preset time length is smaller than or equal to the preset capacity increment is used as the basis for judging whether to stop charging or not, the influence of the internal resistance change of the electric energy storage unit on the charging current in the charging process is fully considered, the influence of the internal resistance change of the electric energy storage unit on the determination of whether to stop charging or not is reduced, the charging time length is ensured to be short, and meanwhile, the fact that the actual charging capacity of the electric energy storage unit meets the user requirements each time of charging is guaranteed.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure.

Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a flowchart illustrating a charging control method according to an exemplary embodiment, which is applied to an electronic device including an electric energy storage unit, as shown in fig. 1, and includes the steps of:
s100: monitoring the real-time charging capacity of the electric energy storage unit in the charging process;
s110: when the real-time charging capacity is larger than or equal to the set capacity, monitoring the charging capacity increment of the electric energy storage unit within a preset time;
s120: and when the increment of the charging capacity in the preset time length is less than or equal to the preset capacity increment, stopping charging.
The real-time charging capacity may be used to represent the total amount of power currently stored by the electrical energy storage unit. Illustratively, in step S100, the real-time charging capacity of the electrical energy storage unit may be monitored in real time by the fuel gauge.
The set capacity may be determined according to a rated capacity of the electric energy storage unit. For example, the set capacity may be less than or equal to a rated capacity of the electrical energy storage unit. Here, the rated capacity of the electric energy storage unit may be set according to a user input. The rated capacity is determined for a particular electrical energy storage unit.
Illustratively, the set capacity and the preset capacity increment are obtained by performing charge and discharge test training on the sample electric energy storage unit at a preset temperature.
It should be noted that, when the real-time charging capacity of the electric energy storage unit is greater than or equal to the set capacity, it can be considered that the electric quantity stored in the electric energy storage unit at this time can meet the design requirement of the electric energy storage unit. I.e. the set capacity, can be regarded as the minimum capacity that needs to be charged when charging the electrical energy storage unit.
When the implemented charging capacity of the electrical energy storage unit is greater than or equal to the set capacity, the electrical energy storage unit may continue to be charged by trickle charging. It can be understood that by continuing to use trickle charge, the electric energy storage unit can be actually saturated when the charging is stopped, so as to prolong the time that the electric energy storage unit can be used after completing one charging. However, the trickle charge method requires a small charging current, and when the trickle charge method is used until full charge, a long charging time is required.
During charging, the internal resistance of the energy storage unit becomes larger as the charging time increases. In the trickle charge stage, the increase of the internal resistance of the electric energy storage unit can cause the further reduction of the charging current, so that the charging time is prolonged, and the user experience is influenced.
In the related art, the charging time can be shortened by increasing the charge-off current, and specifically, when the current in the trickle charge phase is reduced to be equal to the charge-off current, the charging is immediately stopped. However, as the internal resistance of the electric energy storage unit gradually increases, the charging current in the trickle charging stage further decreases, so that when the charging current decreases to the charging cutoff current to stop charging, the amount of electricity stored in the electric energy storage unit is not saturated, thereby shortening the service time of the electronic device powered by the electric energy storage unit after the charging is completed, and affecting the user experience.
Therefore, compared with the method that whether the charging current is reduced to the fixed charging cut-off current is used as the basis for judging whether to stop charging, the embodiment of the disclosure uses the charging capacity increment in the preset time length as the condition for judging whether to stop charging after the real-time charging capacity is larger than or equal to the set capacity, reflects the change of the charging speed through the charging capacity increment in the preset time length, reduces the influence of the internal resistance change of the electric energy storage unit on the determination of whether to stop charging, and is favorable for ensuring that the actual charging capacity of the electric energy storage unit meets the requirements of users when the charging is finished each time while ensuring that the charging time length is short.
In some embodiments, the method further comprises:
and adjusting the values of the set capacity and the preset capacity increment according to the cycle number of the electric energy storage unit.
One charge and one discharge over the cycle life of the electrical energy storage unit is referred to as completing one cycle. Here, the cycle life is the total number of cycles that the electric energy storage unit can endure in a certain charging/discharging manner before the available capacity of the electric energy storage unit decreases to a predetermined value.
With the increase of the cycle number of the electric energy storage unit, the electric energy storage unit may have an aging phenomenon, which results in the decrease of the available electric quantity of the electric energy storage unit, so that a user obviously feels that the available time of the electronic device powered by the electric energy storage unit is decreased after completing one-time charging.
Specifically, taking the example that the electric energy storage unit is a lithium ion battery, as the cycle number of the lithium ion battery increases, the resistance inside the lithium ion battery increases, which results in the reduction of the electric quantity that can be actually stored by the electric energy storage unit, and may result in the reduction of the electric quantity that is actually discharged after the electric energy storage unit completes charging, and the endurance time is shortened.
When the value of the set capacity is fixed, along with the increase of the cycle number of the lithium ion battery, the time for the lithium ion battery to reach the fixed set capacity can be increased in the charging process, so that the charging time is prolonged. Or the real-time charging capacity of the lithium ion battery may not reach a fixed set capacity, which may result in that it cannot be determined that charging needs to be stopped, so that the lithium ion battery may be continuously charged, and an overcharge phenomenon of the lithium ion battery occurs, which may result in damage to the lithium ion battery or even a safety accident.
When the value of the preset capacity increment is fixed and unchanged, along with the increase of the cycle number, after the real-time charging capacity of the lithium ion battery is greater than or equal to the set capacity, the charging capacity increment in the preset time is gradually reduced in the process of continuously charging the lithium ion battery. And, the increase of the internal resistance of the lithium ion battery further causes the increment of the charge capacity within the preset time to decrease.
Therefore, when the charging capacity increment in the preset time is reduced to the fixed preset capacity increment and the charging is stopped, the actual charging capacity in the lithium ion battery is possibly smaller and cannot meet the requirements of the user, so that the user can obviously feel the shortening of the endurance time of the lithium ion battery, the actual capacity after the charging is stopped each time can be obviously different, and the electric quantity stability in the service cycle of the lithium ion battery is reduced.
In summary, in the whole service cycle of the electric energy storage unit, a fixed value is set for the set capacity and the preset capacity increment, which may result in an extension of the charging time or damage to the electric energy storage unit, or a large difference of the available electric quantity in the electric energy storage unit after each charging is completed, and poor stability of the electric quantity.
Compared with the method for setting fixed values for the set capacity and the preset capacity increment, the method for setting the capacity of the electric energy storage unit can adjust the values of the set capacity and the preset capacity increment in time according to the cycle number of the electric energy storage unit, achieves automatic dynamic adjustment of the charging stopping condition, guarantees that the capacity actually charged in the electric energy storage unit is within a reasonable range when the charging is stopped, guarantees the stability of electric quantity when the charging is stopped every time in the cycle life of the electric energy storage unit, guarantees that the charging time is within a reasonable range, and is beneficial to guaranteeing user experience.
In some embodiments, before the adjusting the values of the set capacity and the preset capacity increment according to the cycle number of the electrical energy storage unit, the method further includes:
and determining the corresponding relation between the cycle number of the electric energy storage unit and the set capacity and the corresponding relation between the cycle number of the electric energy storage unit and the preset capacity increment according to the result of the charge and discharge test training of the sample electric energy storage unit at the preset temperature.
For example, taking the electrical energy storage unit as a battery and the sample electrical energy storage unit as a sample battery, the process of performing the charge and discharge test training on the sample electrical energy storage unit at the preset temperature may include: the sample cell is charged at a preset temperature (e.g., 23 to 27 degrees celsius), a set capacity corresponding to the number of cycles is determined at different numbers of cycles, and a preset capacity increment corresponding to the number of cycles is determined at different numbers of cycles.
And performing function fitting on the corresponding set capacity determined under different cycle times to determine the corresponding relation between the cycle times and the value of the set capacity. Similarly, function fitting is performed on the corresponding preset capacity increment determined under different cycle times, and the corresponding relation between the cycle times and the value of the preset capacity increment can be determined.
For example, the charging and discharging test training may be performed on a plurality of sample batteries to increase the accuracy of the determined correspondence between the number of cycles of the electric energy storage unit and the set capacity and to increase the accuracy of the determined correspondence between the number of cycles of the electric energy storage unit and the preset capacity increment.
In some embodiments, the adjusting the values of the set capacity and the preset capacity increment according to the cycle number of the electrical energy storage unit includes:
and when the cycle number of the electric energy storage unit is increased, the values of the set capacity and the preset capacity increment are reduced.
Illustratively, the value of the set capacity is decreased from a first set capacity to a second set capacity when the number of cycles is increased from a first threshold to a second threshold;
when the cycle number is increased from the first threshold to the second threshold, the value of the preset capacity increment is decreased from a first preset capacity increment to a second preset capacity increment;
the first threshold, the second threshold, the first set capacity, the second set capacity, the first preset capacity increment and the second preset capacity increment are obtained by performing charge and discharge test training on a sample electric energy storage unit at a preset temperature.
And when the cycle number is greater than or equal to the first threshold and is less than the second threshold, setting the value of the capacity as a first preset capacity, and setting the value of the preset capacity increment as a first preset capacity increment. It should be noted that, when the number of cycles is within the range from the first threshold to the second threshold and the value of the number of cycles is not equal to the second threshold, the value of the set capacity may be a fixed first preset capacity, and the value of the preset capacity increment may be a fixed first preset capacity increment.
And when the cycle number is greater than or equal to a second threshold value, the value of the set capacity is a second set capacity, and the value of the preset capacity increment is a second preset capacity increment. It should be noted that, when the number of cycles is greater than or equal to the second threshold, the value of the set capacity may be a fixed second preset capacity, and the value of the preset capacity increment may be a fixed second preset capacity increment.
That is, the first set capacity and the second set capacity corresponding to the threshold intervals in which the number of cycles is different are different, and the higher the average number of cycles corresponding to the threshold interval in which the number of cycles is, the lower the corresponding first set capacity and second set capacity are.
Specifically, taking a lithium ion battery with a cycle life of 400 times and a rated capacity of 2000 ma as an example, the first threshold may be 0, the second threshold may be 200, the first set capacity may be 2000 ma, the second set capacity may be 1900 ma, the first set capacity increment may be 50 ma, and the second set capacity increment may be 30 ma.
At this time, the cycle life may be divided into two intervals, including a first interval ([0,200 ]) and a second interval ([200, 400]), and for the cycle number whose value is in the first interval, the value of the corresponding set capacity is the same, and the value of the corresponding preset capacity increment is also the same. For the cycle times with the values in the second interval, the corresponding values of the set capacity are the same, and the corresponding values of the preset capacity increment are also the same. For the cycle times with the values in the first interval and the cycle times with the values in the second interval, the values of the corresponding set capacities are different, and the values of the corresponding preset capacity increments are also different.
When the cycle number is more than or equal to 0 and less than 200, the values of the set capacities are the first set capacity, namely 2000 milliampere hours; the value of the preset capacity increment may be a first preset capacity increment, i.e., 50 ma-hrs. When the cycle number is more than or equal to 200, the values of the set capacities are all the second set capacity, namely 1900 ma hours; the value of the predetermined capacity increment may be a second predetermined capacity increment, i.e., 30 ma-hrs.
It is noted that a plurality of thresholds may be included in the method provided by this example, such as a first threshold, a second threshold, a third threshold, a fourth threshold, and so on.
When the cycle life is divided by setting a plurality of thresholds, such as a first threshold, a second threshold, a third threshold, a fourth threshold, and the like, a plurality of values are correspondingly set for the set capacity and the preset capacity increment.
It can be understood that, no matter the cycle life is divided into several intervals, when the value of the cycle number increases from one interval range to another interval range, the value of the set capacity decreases, and the value of the preset capacity increment also decreases.
In some embodiments, the method further comprises:
monitoring the real-time charging current of the electric energy storage unit;
and stopping charging when the real-time charging current is less than or equal to a preset cut-off current.
Illustratively, the preset cutoff current is determined according to the preset capacity increment.
For example, after the real-time charging capacity is greater than or equal to the set capacity, the electric energy storage unit may be continuously charged by trickle charging.
As the number of cycles increases, the increase in internal resistance of the electrical energy storage unit results in a decrease in charging current during the trickle charge process described above. When the real-time charging current is reduced to be equal to or less than the preset cut-off current, if the electric energy storage unit is continuously charged, the charging efficiency is low due to the fact that the real-time charging current is small, the charging time is prolonged, and even the electric energy storage unit is damaged.
In the embodiment of the disclosure, by setting the preset cutoff current determined according to the preset capacity increment, after the real-time charging capacity is greater than or equal to the set capacity, the charging of the electric energy storage unit can be stopped in time by monitoring the real-time charging current and stopping the charging when the real-time charging current is less than or equal to the preset cutoff current, so that the charging duration is ensured, the electric energy storage unit can be protected, and the user experience can be ensured.
Example 1
With the development of the fifth Generation mobile communication technology (5th-Generation mobile networks, 5G), more and more life and work can be done through the network. Mobile terminals such as mobile phones are used as mobile internet portals, and increasingly affect various fields of user life. Users are increasingly demanding mobile phones. For example, users require a battery of a mobile phone to have a larger capacity and a faster charging speed.
In charging a battery, in order to reach the saturation of the battery capacity, a fast charging phase is usually performed first, and then a trickle charging phase is performed. The trickle charge stage can be used for compensating the capacity loss of the battery due to self-discharge after the battery is fully charged, and prolonging the service time of the battery.
In the related art, since the charging current in the trickle charging stage is changed in real time, the charging is stopped when the charging current is reduced to be equal to the charge cutoff current. It should be noted that, since the charging current in the trickle phase is small and the charging time is long, in order to meet the requirement of fast charging, in the related art, the charging time can be shortened by increasing the value of the charging off-current.
However, when the value of the charging cutoff current is increased, the trickle charging time is shortened, so that the battery does not reach an electric quantity saturation state when the charging current is reduced to the charging cutoff current, the service life of the battery after being charged once is shortened, and the user experience is influenced.
As the number of charging cycles increases, the internal resistance of the battery also increases, and the charging current in the trickle charge phase further decreases. Therefore, as the number of cycles increases, shortening the charging time by increasing the charge cutoff current results in a smaller actual capacity in the battery when the charging is stopped, resulting in a shorter usage time after the battery has been charged. In addition, the actual capacity of the battery is obviously different when the battery stops charging every time, so that the stability of the available electric quantity of the battery after the battery is charged every time in the service cycle of the mobile phone is reduced.
In order to meet the requirement of a user on quick charging of mobile terminals such as a mobile phone, and ensure that the actual capacity of the mobile phone is within a reasonable range when charging is completed, and normal use of the user is not affected, in this example, an electric energy storage unit is a battery, a charging control method is provided, and the method includes the following steps:
the method comprises the following steps: during the charging process of the battery, the real-time charging capacity (Q) of the battery is accumulated by an electricity meterbat) And determining a real-time charging current (I)t)。
Step two: during the charging process of the battery, when the real-time charging capacity is larger than or equal to the set capacity, the charging capacity increment (Q) in the preset time length (t, t is larger than 0) is monitored in real time through the charging control integrated circuitt). Here, theThe preset duration may include: 1 minute, 3 minutes, or 5 minutes, etc.
Step three: and when the increment of the charging capacity in the preset time length is less than or equal to the preset increment, stopping charging. Or, when the real-time charging capacity is larger than or equal to the set capacity and the real-time charging current is smaller than or equal to the preset cut-off current (I)min) When the charge is stopped, the charge is immediately stopped.
It should be noted that when the charging is stopped because the increment of the charging capacity within the preset time period is small rain or equal to the preset increment of the capacity, the real-time charging current at this moment can be regarded as the preset cutoff current.
Illustratively, the set capacity may be by rated capacity (Q)min) Expressed by the product of the first percentage (A%), the preset capacity increment may be represented by a cutoff capacity increment (Q)op) And the second percentage (B%).
Illustratively, the rated capacity may be equal to the capacity noted on the battery nameplate. When the battery has no nameplate or the battery nameplate has no capacity marked, the rated capacity can be determined by performing experimental tests on the sample battery at a preset temperature.
Illustratively, the cutoff capacity increment and the preset cutoff current may be determined by performing experimental tests on the sample cell under preset temperature conditions.
Specifically, the method of determining the rated capacity, the cutoff capacity increment, and the preset cutoff current may include: performing an experimental test on the sample battery by a standard charging and discharging method within a preset temperature range (for example, 23 to 27 ℃), and determining the rated capacity of the sample battery and the preset cutoff current of the sample; in the stage of charging the sample battery, the real-time charging capacity of the sample battery is obtained through accumulation of the electricity meter, and the real-time charging current of the sample battery is determined. And after the actual charging capacity of the sample battery is greater than or equal to the rated capacity, monitoring the charging capacity increment of the battery within a preset time period, and stopping charging under the condition of sample ending capacity increment with different values.
And selecting the sample cut-off capacity increment, which is in a reasonable range of the actual capacity in the battery when the charging is stopped and the charging time length is also in the reasonable range, as the cut-off capacity increment by comparing the actual capacity and the charging time length in the sample battery when the charging is stopped under the sample cut-off capacity increments with different values.
Here, the standard charge and discharge method may include: for the battery in the lowest electric quantity state, firstly, charging the battery in a constant-current charging mode, then, carrying out constant-voltage charging, and finally, carrying out trickle charging until the electric quantity of the battery is determined to be saturated through an electricity meter; and finally discharging the battery with the saturated capacity to the lowest capacity state.
Here, the time at which the charging is most suitably stopped may be represented as: the actual capacity of the battery is large at this time, and the charging period during which the charging is stopped is also short at this time.
For example, for a sample cell rated at 2000 ma-hrs, the minimum capacity may be 2000 ma-hrs, the preset duration may be 5 minutes, the cutoff capacity increment may be 50 ma-hrs, and the preset cutoff current may be 100 ma.
It is understood that the reasonable range of the actual charging capacity and the reasonable range of the charging duration can be specifically set according to the user's requirement and the product location of the battery.
For example, for a sample battery with a rated capacity of 2000 ma, since redundancy is provided to the capacity of the battery during the battery design process, a reasonable range of the actual capacity of the battery at the time of completing the charging may be considered to include: 1600 ma-hr to 2100 ma-hr, or 1800 ma-hr to 2200 ma-hr, etc. When the capacity of the battery after charging is within a reasonable range, the capacity stored in the battery after one-time charging can be considered to meet the requirements of users.
As another example, for a sample battery rated at 2000 ma-hrs, it may be considered that a reasonable range of charge time periods required to fully charge the 2000 ma-hrs battery may include: 20 minutes to 40 minutes, e.g., 25 minutes, 30 minutes, or 35 minutes, etc.
It is to be noted that, in determining the rated capacity, a completely new battery, that is, a battery having a cycle number of 0 may be used as the sample battery. For a battery with a cycle number of 0, the sample battery performance can be considered to be maintained at factory settings, and no loss occurs due to cyclic charge and discharge.
It can be understood that the performance and kind of the sample battery are the same as those of the battery actually required to be subjected to the charge control.
In some embodiments, the set capacity comprises a product of a rated capacity of the electrical energy storage unit and a first percentage;
the preset capacity increment comprises a product of a cutoff capacity increment of the electric energy storage unit and a second percentage;
the adjusting the values of the set capacity and the preset capacity increment according to the cycle number of the electric energy storage unit comprises:
adjusting down the values of the first and second percentages as the number of cycles of the electrical energy storage unit increases;
and the rated capacity, the cut-off capacity increment, the corresponding relation between the cycle number and the first percentage and the corresponding relation between the cycle number and the second percentage are determined by performing charge and discharge test training on the sample electric energy storage unit at a preset temperature.
For example, the values of the first percentage and the second percentage may be adjusted according to the number of cycles of the battery.
For example, when the number of cycles is N1When the first percentage takes on a value of1% and the value of the second percentage may be B1Percent; when the number of cycles is N2When the first percentage takes on a value of2% and the value of the second percentage may be B2Percent; …, respectively; when the number of cycles reaches NkWhen the first percentage takes on a value ofk% and the value of the second percentage may be Bk% of the total weight of the composition. Wherein N is1≤N2≤…≤Nk，100≥A1≥A2≥…≥Ak＞0，B1≥B2≥…≥Bk＞0。
For another example, when the number of cycles is greater than or equal to 0 and the number of cycles is less than 200, the first percentage may be 100% and the second percentage may be 100%. When the number of cycles is greater than or equal to 200 and the number of cycles is less than 400, the first percentage may be 95% and the second percentage may be 60%.
It should be noted that the correspondence between the number of battery cycles and the values of the first percentage and the second percentage may also be determined by performing experimental tests on the sample battery.
According to the method, firstly, the rated capacity, the charge cut-off capacity, the preset cut-off current, the relation between the cycle number and the first percentage value and the relation between the cycle number and the second percentage value of the battery are determined through experimental tests, then in the charging process, after the real-time charge capacity reaches the set capacity, the increment of the charge capacity in the preset time is used as the basis for judging whether to stop charging, and the set capacity and the preset capacity increment are dynamically adjusted according to the cycle number, so that the automatic dynamic adjustment of the charge stop condition is realized, the actual charge capacity of the battery is ensured to be in a reasonable range, the stability of the electric quantity when the charging is stopped in the cycle life of the battery is ensured, the charge duration is also ensured to be in a reasonable range, and the user experience is favorably ensured.
In addition, this example can guarantee that the capacity of battery keeps in certain range in the later stage of battery cycle life through distinguishing the different cycle number of battery, according to the cycle number adjustment settlement capacity of battery and predetermine the capacity increment, improves user's use and experiences.
In addition, because the internal resistance of the battery is constantly changed in the charging process, compared with the case that a fixed cut-off current is adopted as a basis for judging whether to stop charging in the whole cycle life of the battery, in the example, after the real-time charging capacity is greater than or equal to the set capacity, the charging capacity increment in the preset time duration is used as a basis for judging whether to stop charging, the real-time change of the charging cut-off current can be realized, the purpose of ensuring the battery capacity is achieved, the probability of overlow charging capacity caused by the fixed cut-off current is reduced, and the user experience is facilitated.
