The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art without any inventive work based on the embodiments in the present application are within the scope of protection of the present application.
Fig. 1 is a schematic flow chart illustrating a battery charging method according to an embodiment of the present disclosure. The battery charging method is applied to electronic equipment, wherein the electronic equipment can be computer equipment such as a smart phone, a PDA and a tablet personal computer. It should be noted that the battery charging method according to the embodiment of the present application is not limited to the steps and the sequence in the flowchart shown in fig. 1. Steps in the illustrated flowcharts may be added, removed, or changed in order according to various needs. As shown in fig. 1, the battery charging method includes the steps of:
And 102, judging whether the battery is in a constant current charging state. If the battery is in the constant current charging state, step 103 is executed. If the battery is not in the constant current charging state, the process returns to step 102.
And 103, detecting the charging voltage of the battery in real time.
As shown in fig. 2, the charging process of the battery is generally divided into a pre-charging phase I, a constant current charging phase II, and a constant voltage charging phase III. In the pre-charging stage I, the battery voltage value Ubat(i.e., charging voltage) and battery current value Ibat(i.e., the charging current) rapidly climbs, and the charging duration is short; after the pre-charging stage I is finished, entering a constant current charging stage II (a rapid charging stage); in the constant current charging stage II, the charging voltage is slowly increased, and the charging current is kept unchanged; when the charging voltage reaches the cut-off voltage UmaxAnd entering a constant voltage charging stage III, wherein the charging voltage is kept unchanged and the charging current is gradually reduced until the battery is fully charged.
In the constant current charging process, the battery can be charged quickly due to the adoption of larger current for charging, so that the charging time of the battery is saved. In the constant voltage charging phase III, since the charging current of the battery is small and the charging current becomes smaller as time goes on, the charging speed in the constant voltage charging phase III is slow. In order to increase the charging speed of the battery, it should be required to extend the time for constant current charging and/or shorten the time for constant voltage charging.
Since the charging current of the battery remains unchanged during the constant-current charging phase II, the charging voltage generally reaches a peak value at the end of the constant-current charging phase II, and the charging power of the battery is equal to the product of the charging current and the charging voltage, as shown by a curve P1 in fig. 3, the charging power of the battery also reaches a peak value at the end of the constant-current charging phase II. It can be seen that, in most of the time of the constant-current charging phase II, the characteristics of the battery and the output capability of the charging device are not fully utilized, and the charging power of the battery has a certain promotion space, for example, the charging power can be promoted to an ideal value as shown by the curve P2.
In the embodiment of the application, the charging current mainly aiming at the constant current charging process is gradually adjusted, and the charging power of the battery is improved in the constant current charging stage, so that the energy absorbed by the battery in the constant current charging stage is increased, the energy required to be absorbed in the constant voltage charging stage can be reduced, the constant voltage charging time is shortened, the total charging time can be shortened, and the charging speed is improved.
And 104, judging whether the detected charging voltage reaches the safe cut-off voltage of the battery. If the charging voltage of the battery does not reach the safety cut-off voltage, step 105 is executed. If the charging voltage of the battery reaches the safe cut-off voltage, step 106 is executed.
In this embodiment, the safe cut-off voltage is a cut-off voltage set when the battery enters a constant current charging, and the safe cut-off voltage is generally smaller than the safe voltage of the battery. The safe voltage of the battery is determined by the cell material of the battery, for example, the safe voltage of the battery may be 4.3V, 4.4V, 4.5V, etc. according to the cell material. It is understood that, in order to secure the safety of the constant voltage charging, the safety cut-off voltage is generally set to be less than the safety voltage of the battery, for example, the safety cut-off voltage may be 50 Millivolts (MV) less than the safety voltage of the battery.
And 105, adjusting the charging current of the battery to enable the actual charging power of the battery to reach a preset maximum threshold value. The flow returns to step 103 to continue to detect the charging voltage of the battery in real time.
In some embodiments, the maximum threshold value of the charging power of the battery may be determined according to the output capability of a charging device, such as an adapter, a charging line, and the endurance capability of the battery. The maximum threshold of the charging power of the battery may be obtained according to factory test data of the battery.
It is understood that, during the constant current charging, since the charging voltage is gradually increased while the maximum threshold of the charging power of the battery is fixed, in order to make the actual charging power of the battery reach the maximum threshold as much as possible, it is necessary to gradually adjust the charging current according to the charging voltage which is continuously changed. Fig. 4 shows a diagram of the charging current versus the charging voltage of a battery in an ideal state during constant-current charging.
And 106, carrying out constant-voltage charging on the battery at the safe cut-off voltage.
According to the battery charging method provided by the embodiment of the application, the charging current is adjusted in the constant current charging stage to improve the charging power of the battery in the constant current charging stage, so that the energy absorbed by the battery in the constant current charging stage is increased, the energy required to be absorbed in the constant voltage charging stage can be reduced, the constant voltage charging time is shortened, the total charging time can be shortened, and the charging speed is improved.
In some embodiments, the step 105 may include: and adjusting the current charging current according to the maximum threshold value of the charging power of the battery, the current charging voltage of the battery and the corresponding relation between the charging current and the charging power and the charging voltage, so that the current charging power of the battery reaches the maximum threshold value.
Specifically, in the first embodiment, referring to fig. 5, the step 104 may include:
It is understood that, in order to make the current charging power of the battery reach the maximum threshold value as much as possible, the preset time interval should be shortened as much as possible, for example, the preset time interval is set to be 5 seconds, 10 seconds, 30 seconds, 1 minute, etc., so that the current charging voltage of the battery can be sampled as much as possible.
In a second embodiment, referring to fig. 6, the step 104 may include:
step 601, presetting a charging parameter table, wherein the charging parameter table is used for recording multiple groups of charging parameters of the battery in a constant current charging process, each group of charging parameters comprises charging voltage and charging current, and the product of the charging voltage and the charging current in each group of charging parameters is equal to the maximum threshold value of the charging power of the battery.
In the second embodiment, the preset charging parameter table specifically includes:
detecting a plurality of charging voltages of the battery in a constant current charging process in advance;
respectively calculating the charging current corresponding to each pre-detected charging voltage according to the maximum threshold value of the charging power of the battery, each pre-detected charging voltage and the corresponding relationship between the charging current and the charging power and the charging voltage, wherein the product of each pre-detected charging voltage and the charging current corresponding to the pre-detected charging voltage is equal to the maximum threshold value of the charging power of the battery; and
setting a charging parameter table, and recording a plurality of groups of charging parameters in the charging parameter table, wherein each group of charging parameters comprises a pre-detected charging voltage and a charging current corresponding to the pre-detected charging voltage.
It can be understood that, in the second embodiment, in the initial state of the constant current charging process, if the charging current corresponding to the current charging voltage is not obtained from the charging parameter table, the battery is subjected to constant current charging with a preset initial charging current, and the step 602 is returned to continue to obtain a new current charging voltage of the battery.
It is understood that, after the output current of the current output device is adjusted at least once according to the acquired charging current, if the charging current corresponding to the new current charging voltage is not acquired from the charging parameter table, the previous acquired charging current is continued to control the output current of the current output device, and the step 602 is returned to continue to acquire the new current charging voltage of the battery.
It can be understood that, in the second embodiment, since the charging parameter table records the charging parameters corresponding to the battery at a plurality of times in the constant current charging process, the output current of the current output device can be adjusted only by continuing to call data according to the new current charging voltage in the charging process, that is, by continuing to obtain the corresponding charging current from the charging parameter table according to the new current charging voltage obtained continuously, so that the current charging power of the battery reaches the maximum threshold value.
In a third embodiment, referring to fig. 7, the step 104 may include:
step 701, presetting a charging parameter table, wherein the charging parameter table is used for recording multiple groups of charging parameters of the battery in a constant current charging process, each group of charging parameters comprises charging voltage and charging current, and the product of the charging voltage and the charging current in each group of charging parameters is equal to the maximum threshold value of the charging power of the battery.
Please refer to the detailed description of the second embodiment above for a detailed procedure for setting the charging parameter table.
In the third embodiment, each group of charging parameters corresponds to a charging time, and a preset time threshold is set between two adjacent charging times in the plurality of charging times corresponding to the plurality of groups of charging parameters, for example, as shown in fig. 8, the preset time threshold may be set to Δ t. It will be appreciated that after determining the charging current for each charging instant, the charging current I per unit time Δ t can be determinedbatSuch as shown by the fitted curve I1 in fig. 8. It is understood that when the value of the preset time threshold Δ t is sufficiently small, the charging current trends along the charging time as shown in the curve I2.
Step 702, obtaining a current charging voltage of the battery.
Step 704, adjusting the output current of the current output device according to the obtained charging current, so that the current charging power of the battery reaches the maximum threshold value.
Step 705, after the preset time threshold, continuously obtaining the charging current corresponding to the next charging time from the charging parameter table.
Step 706, readjusting the output current of the current output device according to the charging current continuously obtained, so that the current charging power of the battery reaches the maximum threshold value. The flow returns to the step 705, and the steps 705 to 706 are continuously executed until the charging voltage of the battery reaches the safe cut-off voltage.
It can be understood that, in the third embodiment, since a preset time threshold is spaced between two adjacent charging moments, after the charging current corresponding to the current charging voltage is obtained from the charging parameter table at least once, data is called continuously only by timing in the charging process, that is, after the preset time threshold, the charging current corresponding to the next charging moment is obtained from the charging parameter table continuously, and the output current of the current output device can be readjusted, so that the current charging power of the battery reaches the maximum threshold, and the current charging voltage of the battery does not need to be obtained before the charging current is obtained from the charging parameter table each time.
According to the battery charging method provided by the embodiment of the application, aiming at the defect that the traditional charging method cannot fully utilize the output capacity of charging equipment, such as an adapter, in the constant-current charging stage of the battery, an ideal charging current curve is fitted in a way of configuring the charging current in a segmented and timed mode, and the purpose of constant-power charging is approximately achieved, so that the output capacity of a current output device is utilized to the maximum extent, the energy absorbed by the battery in the constant-current charging process is increased, and the charging speed is further accelerated.

The adjusting module 14 is configured to adjust the output current of the current output device according to the calculated charging current, so that the current charging power of the battery reaches the maximum threshold.
It is understood that, in order to make the current charging power of the battery reach the maximum threshold value as much as possible, the preset time interval should be shortened as much as possible, for example, the preset time interval is set to be 5 seconds, 10 seconds, 30 seconds, 1 minute, etc., so that the current charging voltage of the battery can be sampled as much as possible.
In a second embodiment, the setting module 11 is further configured to preset a charging parameter table, where the charging parameter table is configured to record multiple sets of charging parameters of the battery in a constant current charging process, where each set of charging parameters includes a charging voltage and a charging current, and a product of the charging voltage and the charging current in each set of charging parameters is equal to a maximum threshold of the charging power of the battery.
Specifically, the obtaining module 12 is further configured to obtain a plurality of charging voltages of the battery during the constant current charging process, which are detected in advance by the detecting device.
