The disclosure relates to the field of charger design, and in particular, to a method and an apparatus for controlling output current of a charger.
Background
In the early days, people usually adopt a charger to charge when using large current, which causes the charger to generate heat seriously and affects the charging efficiency. People in later period use double chargers to charge so as to relieve the serious heating condition of one charger.
In the related art, in the constant current charging stage, the output currents of the main charger and the sub charger are each half of the total output current. And the primary charger, in contrast to the secondary charger, supplies power to the end load in addition to charging the battery.
The temperature difference between the two chargers is too large due to the fact that the main charger supplies extra power to the terminal load, and the main charger and the auxiliary charger are located at different positions on the circuit board, so that the terminal is locally overheated.
Disclosure of Invention
The disclosure provides a charger output current control method and device. The technical scheme is as follows:
according to a first aspect of the embodiments of the present disclosure, there is provided a charger output current control method, which is applied to a terminal including a first charger, a second charger and a battery, the method including: when the first charger and the second charger charge the battery, acquiring the temperature of the first charger and the temperature of the second charger; calculating a difference between the temperature of the first charger and the temperature of the second charger; and when the absolute value of the difference is larger than a preset difference threshold value, adjusting the output current of a charger with high temperature in the first charger and the second charger to be low, and adjusting the output current of a charger with low temperature in the first charger and the second charger to be high, wherein the sum of the output current of the first charger and the output current of the second charger is equal to a constant total output current.
The temperature difference value of the first charger and the second charger is calculated in real time, when the absolute value of the difference value is larger than the preset difference value threshold value, the output current of the charger with higher temperature is reduced, the output current of the charger with lower temperature is increased to reduce the temperature difference between the first charger and the second charger, the technical problem that the terminal is locally overheated due to the fact that the temperature difference between the first charger and the second charger is too large during parallel charging is solved, and the technical effect of keeping the temperatures of the first charger and the second charger close is achieved. Because the sum of the output currents of the first charger and the second charger is equal to the constant total output current, the problem that the battery is lost due to the overhigh total output current when the output currents of the first charger and the second charger are controlled is avoided, and the problem that the charging efficiency of the battery is reduced due to the overhigh total output current is also avoided.

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 charger output current control method according to an exemplary embodiment, which is applied to a terminal including a first charger, a second charger and a battery, as shown in fig. 1, and includes the following steps.
In step 101, the temperature of the first charger and the temperature of the second charger are acquired while the first charger and the second charger charge the battery.
In step 102, a difference between the temperature of the first charger and the temperature of the second charger is calculated.
In step 103, when the absolute value of the difference is greater than a predetermined difference threshold, the output current of the charger with a high temperature of the first charger and the second charger is adjusted to be low, and the output current of the charger with a low temperature of the first charger and the second charger is adjusted to be high, wherein the sum of the output current of the first charger and the output current of the second charger is equal to the constant total output current.
In summary, according to the charger output current control method provided in the embodiment of the present disclosure, the temperature difference between the first charger and the second charger is calculated in real time, and when the absolute value of the difference is greater than the predetermined difference threshold, the output current of the charger with a higher temperature is decreased, and the output current of the charger with a higher temperature is increased to reduce the temperature difference between the first charger and the second charger, so that the technical problem that the terminal is locally overheated due to an excessively large temperature difference between the first charger and the second charger during parallel charging is solved, and the technical effect of keeping the temperatures of the first charger and the second charger similar is achieved. Because the sum of the output currents of the first charger and the second charger is equal to the constant total output current, the problem that the battery is lost due to the overhigh total output current when the output currents of the first charger and the second charger are controlled is avoided, and the problem that the charging efficiency of the battery is reduced due to the overhigh total output current is also avoided.
In practical application, when the terminal adjusts the output currents of the first charger and the second charger, the magnitude of the amplitude needs to be definitely adjusted, and at this time, in order to ensure that the sum of the adjusted output current of the first charger and the adjusted output current of the second charger is always equal to the constant total output current, the adjustment amplitudes of the output currents of the first charger and the second charger must be equal, and the adjustment amplitudes should be smaller than the constant total output current.
Fig. 2A is a flowchart illustrating a charger output current control method applied to a terminal including a first charger, a second charger, and a battery according to another exemplary embodiment, as shown in fig. 2A, including the following steps.
In step 201, according to the charging parameter of the first charger and the charging parameter of the second charger, a first initial output current is configured for the first charger, and a second initial output current is configured for the second charger, and the charging parameter reflects the charging capability and the heat dissipation performance of the charger.
In consideration of the current production cost of the terminal, the parameter configurations of the first charger and the second charger used for parallel charging in the terminal may be different, and generally, the configuration of one charger is relatively high, so that in addition to the function of charging the battery, the other charger may also provide electric energy for other devices of the terminal, and the other charger may be used only for charging the battery, so as to improve the charging efficiency of the battery and reduce the charging time of the battery. The first charger and the second charger in the present application may have respective charging parameters that may reflect the maximum output current of the charger, the heat dissipation efficiency per unit time, and the like. Therefore, in the initial stage of parallel charging, the first charger and the second charger can fully utilize the charging performance of the first charger and the second charger according to the charging parameters of the first charger and the second charger, reasonably configure the initial output current, and keep the temperature values of the first charger and the second charger in a relatively reasonable range.
Optionally, a charger with stronger charging capability and better heat dissipation performance is usually configured with higher output current, and a charger with weaker charging capability and poorer heat dissipation performance is usually configured with lower output current.
In another alternative, the terminals may equally configure the initial output currents of the first charger and the second charger.
When the first charger and the second charger charge the battery at the same time, the sum of the output current of the first charger and the output current of the second charger is used as the input current of the battery, that is, the output current of the first charger is used as one part of the input current of the battery, and the output current of the second charger is used as the other part of the input current of the battery.
In step 202, the first charger is controlled to charge the battery according to a first initial output current, and the second charger is controlled to charge the battery according to a second initial output current, wherein the sum of the first initial output current and the second initial output current is equal to a constant total output current.
After the initial output currents of the first charger and the second charger are reasonably configured according to the charging parameters of the first charger and the second charger, if the first charger and the second charger are simultaneously required to charge the battery, the terminal can simultaneously control the first charger and the second charger to charge the battery according to the respective configured initial output currents, and in the process, the sum of the output currents of the first charger and the second charger is a constant total output current.
The constant total output current can ensure the stability of charging the battery, so in order to ensure the stability of charging the battery, the constant total output current can be maintained in the whole regulation process.
In step 203a, the temperature of the first charger and the temperature of the second charger are acquired at predetermined time intervals while the first charger and the second charger charge the battery.
Because the first charger and the second charger can generate partial energy loss in a heating mode when the batteries are charged in parallel, and the first charger and the second charger are arranged at different positions of the terminal, when the temperature difference value of the first charger and the second charger is too large, the terminal can be locally overheated, and the terminal needs to acquire the temperature values of the first charger and the second charger in real time.
The temperature of the first charger and the temperature of the second charger are obtained at predetermined time intervals, which means that the temperature collection frequency of the terminal on the first charger and the second charger is kept unchanged.
In the actual charging process, the temperature of the first charger and the temperature of the second charger are acquired by the temperature sensor in real time and are transmitted to the terminal for real-time monitoring, and when a preset time interval is reached, the terminal can acquire the monitored temperatures.
In a possible implementation manner, a first temperature sensor is arranged in a central area of a first charger, a second temperature sensor is arranged in a central area of a second charger, the first temperature sensor collects the temperature of the central area of the first charger in real time and reports the temperature to a processor or a memory of the terminal, and the second temperature sensor collects the temperature of the central area of the second charger in real time and reports the temperature to the processor or the memory of the terminal.
When the temperature of the first charger and the temperature of the second charger need to be acquired, the processor acquires the acquired temperatures reported by the first temperature sensor and the second temperature sensor at the same time, or reads the acquired temperatures reported by the first temperature sensor and the second temperature sensor from the memory at the same time.
It should be noted that, since the temperature of the charger may change continuously during the charging process, in order to obtain the temperature difference between the first charger and the second charger, the temperature of the first charger and the temperature of the second charger need to be obtained at the same time. Obviously, the first timing of acquiring the temperature of the first charger and the second timing of acquiring the temperature of the second charger may be limited to a very short period of time depending on the capability of the terminal.
In step 203b, when the first charger and the second charger charge the battery, the time length corresponding to the time interval is adjusted down in real time according to the charging time length, the temperature of the first charger and the temperature of the second charger are obtained according to the time interval after the adjustment down, and the charging time length and the time length corresponding to the time interval are in negative correlation.
Generally speaking, the temperature collection of the terminal for the first charger and the second charger may be collected according to a predetermined time interval, or the time interval of the temperature collection may be changed with the charging duration, and the time interval and the charging duration have a negative correlation, where the negative correlation refers to: the longer the charging period, the shorter the determined time interval, whereas the shorter the charging period, the longer the determined time interval. In practical implementation, the functional relationship between the time interval and the charging time period may be linear or non-linear.
In one possible implementation, the time interval of the temperature acquisition varies regularly with the charging duration, and the relationship between the two may be represented by an inverse proportional function, see fig. 2B in particular.
As shown in fig. 2B, the time interval of temperature acquisition is set as a dependent variable f (x) corresponding to the ordinate, the charging time is set as an independent variable x corresponding to the abscissa, and the functional expressions of the two are:
in practical use, k and c in the function expression can be arbitrarily assigned within the constant range according to actual needs.
In the initial charging stage, the charging time length x is small, and the time interval f (x) of temperature acquisition is large. Generally speaking, in the initial stage of parallel charging, the first charger and the second charger reasonably configure the initial output current according to their charging parameters, so that the temperature difference between the first charger and the second charger is not too large, in this case, the temperature of the first charger and the temperature of the second charger can be collected by using a lower frequency, and therefore the temperature collection time interval at this time is larger.
As the charging time period x becomes larger, the time interval f (x) of temperature acquisition also increases. In practical application, due to the positive correlation between power consumption and time, the charger can generate more heat energy along with the extension of charging time, the temperature difference between the first charger and the second charger is gradually increased due to different loads of the first charger and the second charger, and at the moment, the high-frequency acquisition of the temperature of the first charger and the temperature of the second charger are required, so that when the temperature difference between the first charger and the second charger exceeds a preset difference threshold, the terminal can timely adjust the output current of the first charger and the second charger so as to control the temperature difference between the first charger and the second charger.
In step 204, a difference between the temperature of the first charger and the temperature of the second charger is calculated.
After the terminal acquires the temperature of the first charger and the temperature of the second charger in real time, the temperature difference between the first charger and the second charger needs to be calculated to evaluate whether the temperature difference is within a reasonable range, and when the temperature difference exceeds the reasonable range, the terminal is locally overheated due to the fact that the first charger and the second charger are different in position in the terminal.
In step 205, a predetermined adjustment value corresponding to an absolute value of the difference is calculated in a predetermined manner, the absolute value having a positive correlation with the predetermined adjustment value, wherein the predetermined adjustment value is less than the constant total output current.
And the terminal monitors whether the difference value is in a reasonable range in real time according to the difference value between the temperature of the first charger and the temperature of the second charger, when the temperature difference value exceeds the reasonable range, the terminal can adjust the output currents of the first charger and the second charger according to the difference value, and the adjusted amplitude is the preset adjustment value.
When the temperature difference between the first charger and the second charger is large, the output currents of the first charger and the second charger can be regulated and controlled within a short time by increasing the adjustment amplitude, so that the temperature between the first charger and the second charger is balanced, and therefore, the preset adjustment value can be set to change along with the absolute value of the temperature difference in the embodiment.
In one possible implementation, the predetermined adjustment value is positively correlated with an absolute value of a temperature difference between the first charger and the second charger, where the positive correlation is: the larger the absolute value of the temperature difference is, the larger the predetermined adjustment value is determined to be, and similarly, the smaller the absolute value of the temperature difference is, the smaller the predetermined adjustment value is determined to be. In practical implementation, the relationship between the predetermined adjustment value and the absolute value of the temperature difference may be linear or non-linear, and the relationship between the predetermined adjustment value and the absolute value of the temperature difference may be represented by a monotonically increasing asymptotic function, as shown in fig. 2C.
As shown in fig. 2C, the predetermined adjustment value is a dependent variable f (x) corresponding to the ordinate, and the absolute value of the temperature difference is an independent variable x corresponding to the abscissa, and the function expression of the two is:
in practical use, k in the functional expression can be within the constant range according to practical requirementsAnd (4) arbitrarily assigning.
T shown in fig. 2C represents the upper limit of the above-described reasonable range of temperature difference, i.e., the predetermined difference threshold. When the absolute value of the temperature difference value of the first charger and the second charger exceeds T, the terminal can calculate the size of the corresponding preset adjusting value at the moment in real time and carry out real-time regulation and control on the output current of the charger.
It should be noted that the predetermined adjustment value does not mean that the terminal can adjust the output current of the charger without an upper limit, and the predetermined adjustment value must be smaller than the constant total output current due to the limitation of the constant total output current during the charging process, where I shown in fig. 2C is the constant total output current.
It should be added that, after the initial output currents of the first charger and the second charger are both set to I/2, the predetermined adjustment value calculated by the terminal for the first time should be smaller than I/2.
In step 206, when the absolute value of the difference is greater than the predetermined difference threshold, the output current of the charger with higher temperature of the first charger and the second charger is decreased by a predetermined adjustment value, and the output current of the charger with lower temperature of the first charger and the second charger is increased by the predetermined adjustment value, wherein the sum of the output current of the first charger and the output current of the second charger is equal to the constant total output current.
When the absolute value of the temperature difference between the first charger and the second charger is larger than the preset difference threshold value, the terminal distinguishes the charger with higher temperature and the charger with lower temperature according to the temperature data transmitted by the temperature sensor in real time, reduces the output current of the charger with higher temperature by a preset adjustment value calculated in real time to reduce the temperature of the charger, and increases the temperature of the charger by the preset adjustment value by the sensor with lower temperature to increase the temperature of the charger, so that the effect of reducing the temperature difference between the first charger and the second charger is achieved.
Generally, when adjusting the output current of the charger, in order to maintain the charging stability of the battery, the sum of the output currents of the first charger and the second charger needs to be always equal to the above-described constant total output current to ensure the charging efficiency. Therefore, when the terminal adjusts the output currents of the two chargers, the adjustment amplitudes of the output currents of the first charger and the second charger need to be equal, so as to ensure that the sum of the adjusted output currents of the first charger and the second charger is still equal to the constant total output current, and therefore the output currents of the first charger and the second charger can be controlled on the basis of not affecting the charging efficiency to achieve the effect of reducing the temperature difference between the first charger and the second charger.
In addition to the above situation, when the absolute value of the temperature difference between the first charger and the second charger is smaller than the predetermined difference threshold, the terminal does not adjust the output currents of the first charger and the second charger, and the first charger and the second charger keep the current output current and continue to charge the battery.
In summary, according to the charger output current control method provided in the embodiment of the present disclosure, the temperature difference between the first charger and the second charger is calculated in real time, and when the absolute value of the difference is greater than the predetermined difference threshold, the output current of the charger with a higher temperature is decreased, and the output current of the charger with a higher temperature is increased to reduce the temperature difference between the first charger and the second charger, so that the technical problem of local overheating of the terminal due to an excessive temperature difference between the two chargers during parallel charging is solved, and the technical effect of keeping the temperatures of the two chargers close is achieved. Because the sum of the output currents of the first charger and the second charger is equal to the constant total output current, the problem that the battery is lost due to the overhigh total output current when the output currents of the first charger and the second charger are controlled is avoided, and the problem that the charging efficiency of the battery is reduced due to the overhigh total output current is also avoided.
In addition, different initial output currents are configured according to the charging performance and the heat dissipation performance of the first charger and the second charger respectively in the initial charging stage, so that the charging performance of the first charger and the second charger can be fully utilized, and the stability of temperature values of the first charger and the second charger in the initial charging stage is ensured. Meanwhile, the sum of the first initial output current and the second initial output current is equal to the total output current, so that the problem of loss of the battery caused by the excessively high total output current in the initial charging stage is solved, and the problem of reduction of the charging efficiency of the battery caused by the excessively low total output current is also solved.
And calculating a preset adjusting value according to the absolute value of the temperature difference of the two chargers and based on a monotonically increasing asymptotic function, so that the effect of rapidly reducing the difference value of the output currents of the two chargers and further rapidly reducing the temperature difference between the first charger and the second charger is achieved.
Meanwhile, the calculation method based on the monotonically decreasing inverse proportional function according to the charging duration is provided, and the acquisition frequency of the terminal on the temperatures of the first charger and the second charger is controlled in real time, so that when the temperature difference between the first charger and the second charger is too large, the terminal can respond in time, and timely and effective output current regulation and control are carried out on the first charger and the second charger, and the effect of timely reducing the temperature difference between the first charger and the second charger is achieved.
It should be added that, in actual implementation, the method is not limited to the steps in fig. 2A, and some of the steps in fig. 2A may also be implemented separately as an embodiment. For example, step 201, step 202, step 203a, step 204 to step 206 may be implemented separately as an embodiment; for example, step 201, step 202, step 203b, step 204 to step 206 may be implemented separately as an embodiment. In other embodiments, the steps in fig. 2A may be replaced, such as replacing step 201 with: the first charger is configured with a first initial output current of I/2, and the second charger is configured with a second initial output current of I/2.
The following are embodiments of the disclosed apparatus that may be used to perform embodiments of the disclosed methods. For details not disclosed in the embodiments of the apparatus of the present disclosure, refer to the embodiments of the method of the present disclosure.
Fig. 3A is a block diagram illustrating a charger output current control device applied to a terminal including a first charger, a second charger and a battery according to an exemplary embodiment, as shown in fig. 3A, the charger output current control device includes but is not limited to: an acquisition module 301, a first calculation module 302 and a regulation module 303.
The acquisition module 301 may be configured to acquire the temperature of the first charger and the temperature of the second charger when the first charger and the second charger charge the battery.
Because the first charger and the second charger can generate partial energy loss in a heating mode when the batteries are charged in parallel, and the first charger and the second charger are arranged at different positions of the terminal, when the temperature difference value of the first charger and the second charger is too large, the terminal can be locally overheated, and the terminal needs to acquire the temperature values of the first charger and the second charger in real time.
The first calculation module 302 may be configured to calculate a difference between the temperature of the first charger and the temperature of the second charger acquired by the acquisition module 301.
After the terminal acquires the temperature of the first charger and the temperature of the second charger in real time, the temperature difference value of the first charger and the temperature difference value of the second charger need to be calculated to evaluate whether the temperature difference value is within a reasonable range, and when the temperature difference value exceeds the reasonable range, the terminal is locally overheated due to the fact that the positions of the first charger and the second charger in the terminal are different.
The regulation module 303 may be configured to, when the absolute value of the difference calculated by the first calculation module 302 is greater than a predetermined difference threshold, regulate the output current of the charger with a high temperature out of the first charger and the second charger low, regulate the output current of the charger with a low temperature out of the first charger and the second charger high,
wherein the sum of the output current of the first charger and the output current of the second charger is equal to the constant total output current.
When the absolute value of the temperature difference between the first charger and the second charger is larger than the preset difference threshold value, the terminal distinguishes the charger with higher temperature and the charger with lower temperature according to the temperature data transmitted by the temperature sensor in real time, and adjusts the output current of the charger with higher temperature to be lower so as to reduce the temperature of the charger, and adjusts the sensor with lower temperature to be higher so as to increase the temperature of the charger. Thereby reach the effect that reduces the difference in temperature of first charger and second charger.
Generally, when adjusting the output current of the charger, in order to maintain the charging stability of the battery, the sum of the output currents of the first charger and the second charger must be always equal to the above-described constant total output current to ensure the charging efficiency. Therefore, when the terminal adjusts the output currents of the two chargers, the adjustment amplitudes of the output currents of the first charger and the second charger need to be equal, so as to ensure that the sum of the adjusted output currents of the first charger and the second charger is still equal to the constant total output current, and thus the output currents of the first charger and the second charger can be controlled on the basis of not affecting the charging efficiency to achieve the effect of reducing the temperature difference between the first charger and the second charger.
In a possible implementation manner, the regulation module 303 may include: a first regulatory submodule 303a and a second regulatory submodule 303B, as shown in fig. 3B.
The first regulating submodule 303a may be configured to, when the absolute value of the difference calculated by the first calculating module 302 is greater than a predetermined difference threshold, lower the output current of the charger with a high temperature by a predetermined adjustment value, and control the charger to charge the battery according to the lowered output current.
The second regulation submodule 303b may be configured to, when the absolute value of the difference calculated by the first calculation module 302 is greater than a predetermined difference threshold, increase the output current of the charger with a low temperature by the predetermined adjustment value, and control the charger to charge the battery according to the increased output current.
In another possible implementation manner, the charger output current control device may further include: a second calculation module 304.
The second calculation module 304 can be configured to calculate a predetermined adjustment value corresponding to an absolute value of the difference calculated by the first calculation module 302 in a predetermined manner, the absolute value being in a positive correlation with the predetermined adjustment value, the predetermined adjustment value being less than the total output current.
The preset adjustment value has a positive correlation with the absolute value of the temperature difference between the first charger and the second charger, wherein the positive correlation refers to: the larger the absolute value of the temperature difference is, the larger the predetermined adjustment value is determined to be, and similarly, the smaller the absolute value of the temperature difference is, the smaller the predetermined adjustment value is determined to be. In practical implementation, the relationship between the predetermined adjustment value and the absolute value of the temperature difference may be linear or non-linear.
It should be noted that the predetermined adjustment value does not mean that the terminal can adjust the output current of the charger without an upper limit, and the predetermined adjustment value must be smaller than the constant total output current due to the limitation of the constant total output current during the charging process, where I shown in fig. 2C is the constant total output current.
It should be added that, after the initial output currents of the first charger and the second charger are both set to I/2, the predetermined adjustment value calculated by the terminal for the first time should be smaller than I/2.
In another possible implementation manner, the obtaining module 301 may include: a first acquisition sub-module 301a, and/or a second acquisition sub-module 301 b.
The first acquisition submodule 301a may be configured to acquire the temperature of the first charger and the temperature of the second charger at predetermined time intervals.
The temperature of the first charger and the temperature of the second charger are obtained at predetermined time intervals, which means that the temperature collection frequency of the terminal on the first charger and the second charger is kept unchanged.
In the actual charging process, the temperature of the first charger and the temperature of the second charger are acquired by the temperature sensor in real time and are transmitted to the terminal for real-time monitoring, and when a preset time interval is reached, the terminal can acquire the monitored temperatures.
And/or the presence of a gas in the gas,
the second obtaining submodule 301b may be configured to adjust a time length corresponding to a time interval in real time according to a charging time length, and obtain the temperature of the first charger and the temperature of the second charger according to the time interval after the adjustment, where the charging time length and the time length corresponding to the time interval have a negative correlation.
Generally speaking, the temperature collection of the terminal for the first charger and the second charger may be collected according to a predetermined time interval, or the time interval of the temperature collection may be changed with the charging duration, and the time interval and the charging duration have a negative correlation, where the negative correlation refers to: the longer the charging period, the shorter the determined time interval, whereas the shorter the charging period, the longer the determined time interval. In practical implementation, the functional relationship between the time interval and the charging time period may be linear or non-linear.
In another possible implementation manner, the charger output current control device may further include: a configuration module 305 and a control module 306.
The configuration module 305 may be configured to configure a first initial output current for the first charger and a second initial output current for the second charger according to the charging parameters of the first charger and the charging parameters of the second charger, where the charging parameters reflect the charging capability and the heat dissipation performance of the chargers.
In consideration of the current production cost of the terminal, the parameter configurations of the first charger and the second charger used for parallel charging in the terminal may be different, and generally, the configuration of one charger is relatively high, so that in addition to the function of charging the battery, the other charger may also provide electric energy for other devices of the terminal, and the other charger may be used only for charging the battery, so as to improve the charging efficiency of the battery and reduce the charging time of the battery. The first charger and the second charger in the present application may have respective charging parameters that may reflect the maximum output current of the charger, the heat dissipation efficiency per unit time, and the like. Therefore, in the initial stage of parallel charging, the first charger and the second charger can fully utilize the charging performance of the first charger and the second charger according to the charging parameters of the first charger and the second charger, reasonably configure the initial output current, and keep the temperature values of the first charger and the second charger in a relatively reasonable range.
Generally, a charger with a stronger charging capability and a better heat dissipation performance is usually configured with a higher output current, and a charger with a weaker charging capability and a poorer heat dissipation performance is usually configured with a lower output current.
In addition, the initial output currents of the first charger and the second charger may be equally arranged in the terminal.
The control module 306 may be configured to control the first charger to charge the battery at the first initial output current configured by the configuration module 305, control the second charger to charge the battery at the second initial output current,
wherein the sum of the first initial output current and the second initial output current is equal to the total output current.
After the initial output currents of the first charger and the second charger are reasonably configured according to the charging parameters of the first charger and the second charger, if the first charger and the second charger are simultaneously required to charge the battery, the terminal can simultaneously control the first charger and the second charger to charge the battery according to the respective configured initial output currents, and in the process, the sum of the output currents of the first charger and the second charger is a constant total output current.
The constant total output current can ensure the stability of charging the battery, so in order to ensure the stability of charging the battery, the constant total output current can be maintained in the whole regulation process.
In summary, the charger output current control device provided in the embodiment of the present disclosure calculates the temperature difference between the first charger and the second charger in real time, and when the absolute value of the difference is greater than the predetermined difference threshold, reduces the output current of the charger with a higher temperature, and increases the output current of the charger with a higher temperature to reduce the temperature difference between the first charger and the second charger, thereby solving the technical problem of local overheating of the terminal due to an excessive temperature difference between the two chargers during parallel charging, and achieving the technical effect of keeping the temperatures of the two chargers close. Because the sum of the output currents of the first charger and the second charger is equal to the constant total output current, the problem that the battery is lost due to the overhigh total output current when the output currents of the first charger and the second charger are controlled is avoided, and the problem that the charging efficiency of the battery is reduced due to the overhigh total output current is also avoided.
In addition, different initial output currents are configured according to the charging performance and the heat dissipation performance of the first charger and the second charger respectively in the initial charging stage, so that the charging performance of the first charger and the second charger can be fully utilized, and the stability of temperature values of the first charger and the second charger in the initial charging stage is ensured. Meanwhile, the sum of the first initial output current and the second initial output current is equal to the total output current, so that the problem of loss of the battery caused by the excessively high total output current in the initial charging stage is solved, and the problem of reduction of the charging efficiency of the battery caused by the excessively low total output current is also solved.
And calculating a preset adjusting value according to the absolute value of the temperature difference of the two chargers and based on a monotonically increasing asymptotic function, so that the effect of rapidly reducing the difference value of the output currents of the two chargers and further rapidly reducing the temperature difference between the first charger and the second charger is achieved.
Meanwhile, the calculation method based on the monotonically decreasing inverse proportional function according to the charging duration is provided, and the acquisition frequency of the terminal on the temperatures of the first charger and the second charger is controlled in real time, so that when the temperature difference between the first charger and the second charger is too large, the terminal can respond in time, and timely and effective output current regulation and control are carried out on the first charger and the second charger, and the effect of timely reducing the temperature difference between the first charger and the second charger is achieved.
