The embodiments described below by referring to the drawings are exemplary only for the purpose of explaining the embodiments of the present application, and are not to be construed as limiting the embodiments of the present application.
Referring to fig. 1 and fig. 3, a charging control method is provided in an embodiment of the present disclosure. The charging control method comprises the following steps:
01: acquiring a preset charging parameter set corresponding to the charging grade;
02: acquiring the current voltage of the battery and the current temperature of the battery 20;
03: acquiring a target current and a temperature fluctuation curve of the battery 20 according to the current voltage, the current temperature and the charging parameter set; and
04: and setting a real-time charging current according to the target current and the temperature fluctuation curve within a preset time period, and charging the battery 20 by using the real-time charging current.
Referring to fig. 2, the present embodiment further provides a charging control apparatus 200, where the charging control apparatus 200 includes a first obtaining module 211, a second obtaining module 212, a third obtaining module 213, and a charging module 214. The first acquiring module 211, the second acquiring module 212, the third acquiring module 213, and the charging module 214 are respectively configured to execute the methods in 01, 02, 03, and 04. That is, the first acquiring module 211 is configured to acquire a preset charging parameter set corresponding to the charging level. The second obtaining module 212 is used for obtaining the current voltage of the battery and the current temperature of the battery 20. The third obtaining module 213 is used for obtaining the current voltage of the battery and the current temperature of the battery 20. The charging module 214 is configured to set a real-time charging current according to the target current and the temperature fluctuation curve within a preset time period, and charge the battery 20 with the real-time charging current.
Referring to fig. 4, the present embodiment further provides a charging control apparatus 100, where the charging control apparatus 100 includes a battery 20, one or more processors 30, and an internal memory 50. The charging control apparatus 100 and the charging control device 200 can be applied to the terminal 1000 shown in fig. 3. One or more processors 30 are used to execute the methods in 01, 02, 03, and 04. That is, the one or more processors 30 are configured to obtain a preset set of charging parameters corresponding to a charging level; acquiring the current voltage of the battery and the current temperature of the battery 20; acquiring a target current and a temperature fluctuation curve of the battery 20 according to the current voltage, the current temperature and the charging parameter set; and setting a real-time charging current according to the target current and the temperature fluctuation curve within a preset time period, and charging the battery 20 by adopting the real-time charging current.
Wherein the current temperature of the battery 20 may be the temperature of the battery 20 itself, such as the temperature of the battery 20 measured directly by a battery fuel gauge. The current temperature of the battery 20 may also be a temperature measured laterally by measuring the case temperature of the terminal 1000 in which the battery 20 is installed. Factors that affect the case temperature of terminal 1000 include the temperature of battery 20 itself, the temperature of the charging-related electronics, and the heat dissipation characteristics of terminal 1000, among others. Of these factors, the temperature of the battery 20 itself contributes a significant proportion to the case temperature, and therefore the current temperature of the battery 20 can also be measured by the current case temperature side of the terminal 1000.
Terminal 1000 includes cell-phone, panel computer, notebook computer, teller machine, intelligent wrist-watch, intelligent bracelet, intelligent household electrical appliances, game machine, first apparent equipment etc.. These terminal devices are often charged by using a fixed charging strategy, and sometimes it is difficult to achieve the effect desired by the user. For example, a user may desire a faster charging rate just before going out to charge the terminal device to an abundant amount of power before going out. Further, for example, when the user plays a game while charging, it may be more desirable that the temperature of the terminal device is not too high to affect the performance of the electronic product when charging. Currently, for the same terminal equipment product, its charging strategy is already determined at the time of departure, so it is difficult to correspondingly implement different charging strategies according to the needs of users.
The charging control method, the charging control device 100, and the charging control apparatus 200 according to the present application can provide a plurality of different charging levels and correspond to different charging strategies. And a preset charging parameter set corresponds to each charging level. The charging control device 100 can obtain a preset charging parameter set corresponding to the charging level, obtain the current voltage of the battery 20 and the current temperature of the battery 20, obtain the target current and the temperature fluctuation curve of the battery 20 according to the current voltage, the current temperature and the charging parameter set, set the real-time charging current according to the target current and the temperature fluctuation curve within a preset time period, and charge the battery 20 with the real-time charging current.
The target current and temperature fluctuation curve are included in a charging parameter set, and the preset charging parameter set is a set of parameter data, obtained through a large number of experiments before the battery 20 leaves a factory, corresponding to the battery 20 under various working conditions. The preset charging parameter sets are different, and the emphasis points during actual charging are also different. For example, the charging manner determined according to the charging parameter set corresponding to the charging level1 may be a charging manner more biased to control the charging temperature in a lower temperature range, and the charging manner determined according to the charging parameter set corresponding to the charging level 5 may be a charging manner more biased to rapid charging with a larger current. Therefore, different charging grades can be selected according to the needs of the user, and different charging strategies can be executed, so that the requirements of the user in different application scenes can be met.
Specifically, the charge control device 100 is able to acquire a preset set of charge parameters corresponding to the charge level. At the first timing, the charge control apparatus 100 can acquire the first voltage of the battery and the first temperature of the battery. The charging control device 100 obtains a first target current and a first temperature fluctuation curve of the battery according to the first voltage, the first temperature and the charging parameter set, sets a real-time charging current within a first preset time interval according to the first target current and the first temperature fluctuation curve, and charges the battery with the real-time charging current within the first preset time interval. The first time is the starting time of a first preset time interval.
The target current is a target charging current value determined in a preset charging parameter set corresponding to a charging level selected by a user according to a current voltage of the battery 20 and a current temperature of the battery 20. I.e. the value of the charging current that is desired to be reached at the present operating conditions. In terminal 1000, the real-time charging current value can be adjusted to change toward the target current value by providing a charging path of terminal 1000, changing a charging voltage of battery 20, or the like. However, as the real-time charging current changes, the real-time temperature of the battery 20 also changes. If the real-time charging current changes dramatically in a short time, the real-time temperature of battery 20 may also change dramatically in a short time, which may affect not only the performance of terminal 1000, but also the service life of battery 20. Therefore, in the process of controlling the real-time current value to change toward the target current value, the temperature fluctuation curve corresponding to the target current in the charging parameter set needs to be referred to, and in the process of increasing the real-time charging current, if the real-time temperature increase range of the battery 20 is large, the real-time charging current is controlled to slow down the increase rate, or the real-time charging current is controlled to stop changing, or the real-time charging current is controlled to decrease, so as to slow down the real-time temperature increase range of the battery 20, so that the real-time temperature fluctuation curve of the battery 20 approaches the temperature fluctuation curve in the charging parameter set. In the process of reducing the real-time charging current, if the real-time temperature decrease range of the battery 20 is large, the real-time charging current is controlled to slow down the rate of reduction, or the real-time charging current is controlled to stop changing, or the real-time charging current is controlled to increase, so as to slow down the real-time temperature decrease range of the battery 20, and make the real-time temperature fluctuation curve of the battery 20 approach the temperature fluctuation curve of the charging parameter set.
Assume that the user selects the first charging level1, and the preset charging parameter set corresponding to the first charging level1 is the charging parameter set V1. At the first time, the current voltage of the battery 20 is the first voltage, and the current temperature of the battery 20 is the first temperature. The target current and the temperature fluctuation curve obtained by the charge control apparatus 100 according to the first voltage, the first temperature, and the charge parameter set V1 are the first target current and the first temperature fluctuation curve. The charge control device 100 sets the real-time charging current within a first preset time interval according to the first target current and the first temperature fluctuation curve, so that the real-time charging current value changes toward the first target current value, and adjusts the change state of the real-time charging current according to the first temperature fluctuation curve.
After the real-time charging current value changes towards the first target current value for a period of time, the current voltage of the battery 20 and the current temperature of the battery 20 may also change and are no longer the first voltage and the first temperature at the first moment, so that the target current and the temperature fluctuation curve need to be readjusted after the first preset time interval elapses, so that the adjusted charging strategy adapts to the working condition of the next time period after the first preset time interval elapses.
At the second time, the current voltage of the battery 20 is the second voltage, and the current temperature of the battery 20 is the second temperature. The target current and the temperature fluctuation curve obtained by the charge control apparatus 100 according to the second voltage, the second temperature, and the charge parameter set V1 are a second target current and a second temperature fluctuation curve. The charge control device 100 sets the real-time charging current within a second preset time interval according to the second target current and the second temperature fluctuation curve, so that the real-time charging current value changes toward the second target current value, and adjusts the change state of the real-time charging current according to the second temperature fluctuation curve. The first preset time interval may be greater than the second preset time interval, or the first preset time interval may be equal to the second preset time interval, or the first preset time interval may be smaller than the second preset time interval.
Therefore, the real-time charging current in the same charging level can determine the target current according to the current voltage of the battery 20, the current temperature of the battery 20 and the corresponding charging parameter value in the current charging level under the working conditions of different time periods, so as to adjust the value of the real-time charging current to change towards the value of the target current and execute the charging strategy in the charging level. The charging control method at the nth time and the nth preset time interval is the same as the above charging control method, and is not described herein again. Wherein N is an integer of 1 or more.

Referring to fig. 2 and 3, in some embodiments, the first obtaining module 211 of the charging control device 200 may include a first processing unit 2111, a second processing unit 2113, and a third processing unit 2115. The first processing unit 2111 is configured to perform the method in 011. The second processing unit 2113 is adapted to perform the method of 013. The third processing unit 2115 is adapted to perform the method in 015.

That is, the one or more processors 30 are further configured to save the charge level input by the user in the first storage space when the user inputs the charge level; receiving the charging level transferred from the first storage space and storing the charging level in the second storage space; and matching the charging parameter set according to the charging level.
Specifically, the internal memory 50 includes a first storage space and a second storage space. In one example, the first storage space is a user space in liunx, and the second storage space is a kernel space in liunx. The charging parameter set includes a plurality of charging parameter sets, such as a charging parameter set V0, a charging parameter set V1, a charging parameter set V2, a charging parameter set V3, and so on, which are not listed herein. After the user enters the charge level, the one or more processors 30 save the charge level entered by the user in the first memory space, awaiting invocation. In one example, the callback function may be used to receive the charge level information transferred from the first storage space and store the charge level information in the second storage space. The one or more processors 30 match the set of charging parameters according to the charging level information in the second storage space. For example, the charging level includes a charging level1, a charging level 2, and a charging level 3, and the charging parameter set includes a charging parameter set V1, a charging parameter set V2, and a charging parameter set V3. When the user selects the charging level1, the charging level1 is matched with the charging parameter set V1 in all the charging parameter sets according to the input of the user. When the user selects the charging level 2, the charging level 2 is matched with the charging parameter set V2 in all the charging parameter sets according to the input of the user. When the user selects the charging level 3, the charging level 3 is matched with the charging parameter set V3 in all the charging parameter sets according to the input of the user.
Referring to fig. 6, in some embodiments, 01: obtain the predetermined charging parameter set that corresponds with the charge level, still include:
017: when the user does not input the charging level, acquiring a default charging level; and
019: and matching the charging parameter set according to the charging level.
Referring to fig. 2 and 3, in some embodiments, the first obtaining module 211 of the charging control device 200 may further include a fourth processing unit 2117 and a fifth processing unit 2119. The fourth processing unit 2117 is configured to perform the method in 017. The fifth processing unit 2119 is for performing the method in 019. That is, the fourth processing unit 2117 is configured to acquire a default charge level when the user does not input the charge level. The fifth processing unit 2119 is configured to match the charging parameter set according to the charging class.
Referring to FIG. 4, in some embodiments, one or more processors 30 are also used to perform the methods in 017 and 019. That is, the one or more processors 30 are further configured to obtain a default charge level when the user does not input a charge level; and matching the charging parameter set according to the charging level.
For example, the charging level includes a charging level 0, a charging level1, a charging level 2, and a charging level 3, and the charging parameter set includes a charging parameter set V0, a charging parameter set V1, a charging parameter set V2, and a charging parameter set V3.

The one or more processors 30 match the set of charging parameters at a charging level 0 without any charging level information in the second storage space.
In another embodiment, the user may also actively select the default charging level 0. After the user inputs the charging level 0, the one or more processors 30 store the charging level 0 input by the user in the first storage space, and wait for calling.

Specifically, after the preset charging parameter set corresponding to the charging level is obtained, the current temperature of the battery 20 may be used to match the temperature interval in the charging parameter set, and the current voltage of the battery 20 may be used to match the voltage interval in the charging parameter set in the corresponding charging parameter set, respectively, a corresponding charging parameter unit may be found according to the matching structure, and the target current and the temperature fluctuation curve of the battery 20 may be read from the charging parameter unit.
For example, the currently selected charging level is a charging level1, and the corresponding charging parameter set is a charging parameter set V1. The charging parameter unit V1[ i ] of the charging parameter set V1 is shown in fig. 7, where i is an integer of 1 or more and 7 or less. Assuming that the current temperature of the battery 20 is 15 ℃, falling within the interval [14 ℃,16 ℃) and the current voltage is 4.0V, falling within the interval [3.7v, 4.3v). The current operating condition of the battery 20 can be matched to the charging parameter unit V1[5] and the target current of the battery 20 is read from the charging parameter unit V1[5] as 1.2A and the temperature fluctuation curve as curve 1.5.

041: acquiring initial charging current at an initial moment of a preset duration;
043: gradually increasing the current value by taking the initial charging current as a starting point to obtain a real-time charging current, wherein when the battery 20 is charged by adopting the real-time charging current, the temperature fluctuation of the battery 20 meets a temperature fluctuation curve; and
045: and gradually reducing the current value by taking the initial charging current as a starting point to obtain a real-time charging current, wherein when the battery 20 is charged by adopting the real-time charging current, the temperature fluctuation of the battery 20 meets a temperature fluctuation curve.
Referring to fig. 2 and 3, in some embodiments, the charging module 214 of the charging control apparatus 200 may include a first obtaining element 2141, a first charging element 2143, and a second charging element 2145. The first fetch component 2141 is used to execute the method in 041. The first charging component 2143 is used to perform the method in 043. The second charging assembly 2145 is configured to perform the method of 045. That is, the first obtaining component 2141 is configured to obtain an initial charging current at an initial time of a preset time period. The first charging component 2143 is configured to gradually increase a current value from an initial charging current as a starting point to obtain a real-time charging current, wherein when the battery 20 is charged with the real-time charging current, a temperature fluctuation of the battery 20 satisfies a temperature fluctuation curve. The second charging component 2145 is configured to gradually decrease the current value from the initial charging current as a starting point to obtain a real-time charging current, wherein when the battery 20 is charged with the real-time charging current, the temperature fluctuation of the battery 20 satisfies the temperature fluctuation curve.
Referring to FIG. 4, in some embodiments, one or more processors 30 are also configured to perform the methods of 041, 043 and 045. That is, the one or more processors 30 are further configured to obtain an initial charging current at an initial time of a preset duration; gradually increasing the current value by taking the initial charging current as a starting point to obtain a real-time charging current, wherein when the real-time charging current is adopted to charge the battery 20, the temperature fluctuation of the battery 20 meets a temperature fluctuation curve; and gradually reducing the current value by taking the initial charging current as a starting point to obtain a real-time charging current, wherein when the battery 20 is charged by adopting the real-time charging current, the temperature fluctuation of the battery 20 meets a temperature fluctuation curve.
Referring to fig. 3, fig. 4 and table 1, for example, when the user selects a charging level1 to charge the terminal 1000, at an initial time of a 1 st preset time period, the one or more processors 30 obtain a current temperature of the battery 20, a current voltage of the battery 20, and an initial charging current of the battery 20 at the initial time of the 1 st preset time period. Assuming that the present temperature of the battery 20 is 15 deg.C, the present voltage of the battery 20 is 4.0V, and the thus matched parameter unit is the parameter unit V1[5], the target current obtained is 1.2A, and the temperature fluctuation curve is the curve 1.5.
If the initial charging current of the battery 20 at the initial time of the 1 st preset time period is 1.0A, the current value is gradually increased from the initial time of the 1 st preset time period by using 1.0A as a starting point, so that the real-time charging current value changes toward 1.2A. Since the real-time charging current value is variable and is often difficult to maintain at 1.2A, it is necessary to adjust the real-time charging current value to make the variable real-time charging current value as close to the target current 1.2A as possible. If the real-time temperature of the battery 20 rises too fast to cause the real-time temperature curve of the battery 20 to deviate from the curve 1.5 in the process of changing the real-time charging current value to 1.2A, the current value may be temporarily decreased, or the increase of the current value may be temporarily stopped, or the increase rate of the current value may be slowed down to slow down the real-time temperature rise of the battery 20, so that the real-time temperature curve of the battery 20 approaches the curve 1.5, and the current value may continue to be increased gradually when the real-time temperature curve of the battery 20 approaches the curve 1.5, so that the real-time charging current value changes to 1.2A. When the real-time charging current value exceeds 1.2A, the current value is gradually reduced to change the real-time charging current value toward 1.2A.
If the initial charging current of the battery 20 at the initial time of the 1 st preset time period is 1.4A, the current value is gradually decreased from the initial time of the 1 st preset time period by using 1.4A as a starting point, so that the real-time charging current value changes toward 1.2A. Since the real-time charging current value is variable and is often difficult to maintain at 1.2A, it is necessary to adjust the real-time charging current value to make the variable real-time charging current value as close to the target current 1.2A as possible. If the real-time temperature curve of the battery 20 deviates from the curve 1.5 due to the too fast real-time temperature decrease of the battery 20 in the process of changing the real-time charging current value toward 1.2A, the current value may be temporarily increased, or the increase of the current value may be temporarily stopped, or the decreasing rate of the current value may be slowed down to slow down the real-time temperature decrease of the battery 20, so that the real-time temperature curve of the battery 20 approaches the curve 1.5, and the current value may be continuously decreased step by step when the real-time temperature curve of the battery 20 approaches the curve 1.5, so that the real-time charging current value changes toward 1.2A. When the real-time charging current value is lower than 1.2A, the current value is increased step by step so that the real-time charging current value changes toward 1.2A.
After the 1 st preset duration is over, at the initial time of the 2 nd preset duration, the one or more processors 30 reacquire the operating condition of the terminal 1000, that is, reacquire the current temperature of the battery 20, the current voltage of the battery 20, and the initial charging current of the battery 20 at the initial time of the 2 nd preset duration. The one or more processors 30 match the parameter unit V1[ i ] within the 2 nd preset duration according to the working condition at the initial time of the 2 nd preset duration, and obtain the target current and temperature fluctuation curve within the 2 nd preset duration. Adjusting the initial charging current of the battery 20 at the initial time of the 2 nd preset duration within the 2 nd preset duration, so that the process of changing the initial charging current of the battery 20 at the initial time of the 2 nd preset duration toward the target current value within the 2 nd preset duration is similar to the adjustment process within the 1 st preset duration, which is not described herein again.
