Technical Field

[0001] The present application belongs to the field of battery management technology, and specifically relates to a battery charging method and charging device, electronic equipment and storage medium. Background Art

[0002] In the related art, when an electronic device charges its internal battery, it generally uses a fuel gauge to record the amount of electricity during the charging process to ensure that the reported battery power is 100%, i.e. fully charged, when charging is completed. The fuel gauge determines whether the reported power is fully charged based on the charging current or voltage.

[0003] When the battery ages, it needs to be charged through a long period of low-current charging to depolarize the battery before it can be fully charged. After the low-current charging process begins, the fuel gauge will immediately report that the battery is fully charged when it detects that the charging current is decreasing, but the battery is not actually fully charged at this time, which will cause the battery discharge capacity to be less than the actual remaining battery capacity, and the battery discharge capacity will be significantly reduced. Summary of the invention

[0026] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited.

In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0028] The battery charging method and charging device, electronic device and storage medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0029] In some embodiments of the present application, a battery charging method is provided. Figure 1 A flowchart of a battery charging method according to some embodiments of the present application is shown. Figure 1 As shown, the method includes:

[0030] Step 102: Control the battery to charge based on a preset current value.

[0031] In the embodiment of the present application, the preset current value is the charging current value of the battery in the current charge and discharge cycle. When the battery is charged, the battery is charged with the above preset current value.

[0032] Step 104 : when the current charging current of the battery is less than or equal to the full-charge current threshold, obtain the current battery capacity of the battery.

[0033] In the embodiment of the present application, the full-charge current threshold is the current threshold when the battery's fuel gauge reports a charge of 100%. Exemplarily, when the battery is in a healthy state, such as for a brand new battery, when it is not fully charged, the charging current remains at a preset current value. When the battery is fully charged, the charging current decreases, and when the charging current decreases to a value equal to or less than the full-charge current threshold, the fuel gauge reports that the battery charge has reached 100%, and the electronic device will display that the battery is fully charged.

[0034] As the number of battery charge and discharge cycles increases, the battery cells will gradually age. When the battery ages, the battery capacity will decrease compared to a brand new battery. In each charge and discharge cycle, when the battery charging is terminated, the current battery capacity of the battery is obtained to obtain the current cumulative capacity CAP2 of the battery. Assuming that the battery capacity when the battery is brand new is CAP1, CAP2 will be less than CAP1.

[0035] Step 106, determining the current capacity ratio of the battery according to the current battery capacity and the initial battery capacity of the battery.

[0036] In the embodiment of the present application, when the battery is aged, it needs to pass a long period of small current to depolarize the battery in order to fully charge the battery. Once the small current triggers the full charge current threshold of the fuel gauge, the fuel gauge will report 100% of the power in advance, while the battery is not yet fully charged. This causes the battery discharge power to be less than the actual battery power.

[0037] To address this problem, this application obtains the current battery capacity at the end of each charge, and calculates the current capacity ratio based on the current capacitance and the initial capacity of the battery. The current capacity ratio is the discharge capacity of the battery when the power meter reports 100% power, while keeping the current full-charge current threshold unchanged. The current capacity ratio can be used to determine whether the discharge capacity of the battery when the power meter reports 100% power is less than the actual remaining capacity of the battery.

[0038] For example, after the battery is charged for the first time, the battery capacity obtained is CAP1, which is the initial battery capacity of a new battery. Assuming that the current battery capacity obtained after the current charging is terminated is CAP2, the current capacity percentage of the battery can be calculated by the following formula:

[0039] ΔCAP=(CAP2-CAP1)÷CAP2;

[0040] Among them, ΔCAP is the current capacity percentage, CAP2 is the current battery capacity, and CAP1 is the initial battery capacity.

[0041] Step 108, based on the comparison result between the current capacity percentage and the capacity percentage threshold, reduce at least one of the full-charge current threshold and the preset current value.

[0042] In the embodiment of the present application, the capacity percentage threshold is the preset battery capacity percentage when the fuel gauge reports a target power of 100%. If the current capacity percentage is less than the capacity percentage threshold, it means that the discharged power of the battery when the fuel gauge reports a power of 100% is less than the actual maximum power of the battery. Otherwise, it means that the discharged power of the battery when the fuel gauge reports a power of 100% matches the actual maximum power of the battery.

[0043] Each time the battery completes a charge, the current battery capacity of the battery is dynamically acquired to determine the current capacity ratio of the battery, that is, the maximum remaining capacity of the current battery relative to when it was new. Based on the current capacity ratio, the full charge current threshold of the battery or the charging current of the battery is dynamically adjusted, such as lowering the charging current threshold or lowering the charging current of the battery, to avoid the problem that when the battery enters the charging process of small current depolarization, the fuel gauge mistakenly thinks that the battery is fully charged and reports 100% of the power, causing the charging to terminate prematurely. The problem of the actual discharge capacity of the battery being reduced due to the fuel gauge reporting the full charge in advance after battery aging is avoided, so that the power display capacity of the battery after aging can always match the actual remaining capacity.

[0044] In some embodiments of the present application, based on the comparison result of the current capacity share and the capacity share threshold, at least one of the full-charge current threshold and the preset current value is lowered, including: when the current capacity share is less than or equal to the capacity share threshold, the full-charge current threshold is reduced by a first current value.

[0045] In the embodiment of the present application, if the current capacity percentage is less than or equal to the capacity percentage threshold, it means that when the current charging current threshold is used as the standard, at the time when the power meter reports 100% power, the battery has not actually been charged to the maximum power. At this time, the full charge current threshold is adjusted to reduce the first current value, wherein the first current value is a preset current value, and the first current value is a constant.

[0046] Exemplarily, assuming that the full-charge current threshold before adjustment is C, and the first current value is ΔC, the full-charge current threshold after adjustment is C-ΔC.

[0047] Figure 2 A schematic diagram showing the correspondence between the full-charge current threshold and the capacity ratio in some embodiments of the present application is shown, such as Figure 2 As shown in the figure, when the battery is in a brand new state, the initial full charge current threshold is C0, and then whenever the current capacity ratio is less than or equal to the capacity ratio threshold, the full charge current threshold is reduced to obtain C1, C2, C3, C4, C5, etc., where the current full charge current is C. This ensures that the discharge capacity after charging matches the actual remaining capacity of the battery, and avoids the problem of the actual discharge capacity of the battery being reduced due to the fuel gauge reporting the full charge in advance after the battery is aged.

[0048] In some embodiments of the present application, after adjusting at least one of the full-charge current threshold and the preset current value based on the comparison result of the current capacity proportion and the capacity proportion threshold, the charging method also includes: when the current capacity proportion is not less than the capacity proportion threshold and the full-charge current threshold is less than the charging current threshold, increasing the full-charge current threshold by a first current value.

[0049] In an embodiment of the present application, if the current capacity percentage is greater than the capacity percentage threshold, it means that when the current charging current threshold is used as the standard, when the power gauge reports 100% power, the battery has reached or is close to the maximum power, and there is no need to reduce the full charge current threshold.

[0050] On this basis, it is determined whether the full-charge current threshold is less than or equal to the charging current threshold. Among them, the charging current threshold is the threshold of the inefficient charging current. When the full-charge current threshold is less than the charging current threshold, the charging capacity is too small in the same charging time, which will affect the battery charging efficiency. Therefore, the full-charge current threshold is relaxed, and the full-charge current threshold is increased by the first current value. For example, assuming that the full-charge current threshold before the current adjustment is C, and the first current value is ΔC, the adjusted full-charge current threshold is (C+ΔC).

[0051] By increasing the full-charge current threshold when the time node when the fuel gauge reports 100% of the power is reasonable, the charging efficiency can be improved and the charging time can be optimized.

[0052] In some embodiments of the present application, based on the comparison result of the current capacity proportion and the capacity proportion threshold, at least one of the full charge current threshold and the preset current value is lowered, including: when the current capacity proportion is less than the capacity proportion threshold, the preset current value is reduced by a second current value.

[0053] In the embodiment of the present application, the preset current value is the charging current when the battery is charged. Under the same charging current, the capacity ratio when the current reaches 100% of the power reported by the fuel gauge is different. As the battery ages, the charging current of the battery will also increase. The battery will be more easily polarized due to the aging of the battery and the high charging current. Therefore, it takes a longer time to charge with a small current to depolarize the battery. This results in the actual discharge capacity of the battery being smaller when the full charge current threshold is triggered.

[0054] Figure 3 A schematic diagram showing the relationship between charging current and capacity ratio in some embodiments of the present application is shown, such as Figure 3 As shown, I max is the maximum charging current of the battery, I 充电 is the preset current value, I min is the minimum charging current of the battery, I 100％ is the full charge current threshold, I截止 The current threshold at which charging of the battery is stopped.

[0055] Therefore, when the current capacity share is less than or equal to the capacity share threshold, reducing the preset current value during charging can effectively alleviate the problem of battery polarization, thereby reducing the depolarization time through small current charging, and further reducing the impact of small current charging triggering the full charge current threshold on the battery capacity.

[0056] Exemplarily, assuming that the preset current value before adjustment is I and the second current value is ΔI, the preset current value after adjustment is I-ΔI.

[0057] Exemplarily, after adjusting and lowering the preset current, the full-charge current threshold may also be adjusted simultaneously, thereby avoiding the problem of a reduction in the actual discharge capacity of the battery due to the fuel gauge reporting full charge in advance after battery aging.

[0058] In some embodiments of the present application, after adjusting at least one of the full-charge current threshold and the preset current value based on the comparison result of the current capacity proportion and the capacity proportion threshold, the charging method also includes: when the current capacity proportion is not less than the capacity proportion threshold and the maximum value of the preset current value is less than the maximum charging current value, increasing the maximum value of the preset current value by a second current value.

[0059] In an embodiment of the present application, if the current capacity percentage is greater than the capacity percentage threshold, it means that when the current charging current threshold is used as the standard, when the power gauge reports 100% power, the battery has reached or is close to the maximum power. At this time, there is no need to reduce the charging current value, that is, the preset current value.

[0060] On this basis, it is determined whether the maximum value of the preset current value is less than or equal to the maximum charging current value. The maximum charging current value is the upper limit of the charging current allowed by the battery. If the maximum value of the preset current value is less than the maximum charging current value, the battery charging efficiency has not reached the highest. At this time, the maximum value of the preset current value is adjusted to increase the second current value, thereby improving the charging efficiency. For example, assuming that the current preset current value is I and the second current value is ΔI, the adjusted preset current value is (I+ΔI).

[0061] By increasing the charging current value when the time node when the fuel gauge reports 100% of the power is reasonable, the charging efficiency can be improved and the charging time can be optimized.
