Description

Technical Field

[0001] This invention relates to the field of battery technology, and more particularly to a charging method, apparatus, electronic device, and readable storage medium. Background Technology

[0002] Depending on the charging current value, constant current charging can be divided into different stages. During the constant current charging process, the battery is switched between different constant current charging stages based on the duration of each stage. The charging current and duration of each constant current charging stage are predetermined.

[0003] To increase charging speed and ensure a large charging current even when the battery is in a high-charge state, the initial charging current is typically high. Resuming charging immediately after stopping during the initial charging phase essentially keeps the battery in the initial charging stage. Prolonged high-current charging can negatively impact battery performance and shorten its lifespan. Summary of the Invention

[0007] When the charging capacity is greater than or equal to the first threshold, the first preset current and the first preset duration are adjusted to obtain the first charging current and the first charging duration of the first charging stage. The first charging current is less than the first preset current and / or the first charging duration is less than the first preset duration. The first preset current is the reference charging current of the first charging stage, and the first preset duration is the reference charging duration of the first charging stage.

[0008] At the first moment, the battery is charged with constant current based on the first charging current and the first charging duration of the first charging phase.

[0010] When the first charging duration is 0, the first charging stage is skipped and the battery is charged with constant current based on the second preset current and the second preset duration of the second charging stage.

[0011] The second charging phase is adjacent to the first charging phase, the second preset current is the reference charging current of the second charging phase, the second preset duration is the reference charging duration of the second charging phase, and the second preset current is less than the first charging current.

[0013] The average charging rate is calculated based on the charging capacity and the time interval between the first and second moments.

[0014] If the average charging rate is greater than or equal to the second threshold, the first charging duration is determined to be 0, and the first charging current of the first charging stage is determined to be the first preset current.

[0015] Optionally, adjusting the first preset current and the first preset duration to obtain the first charging current and the first charging duration when the charging capacity is greater than or equal to the first threshold includes:

[0016] When the charging capacity is greater than or equal to the first threshold, the first preset duration is determined as the first charging duration, and the first preset current is reduced to obtain the first charging current.

[0017] Wherein, the first charging current is greater than the second preset current, and the second preset current is the reference charging current for the second charging stage.

[0018] Optionally, adjusting the first preset current and the first preset duration to obtain the first charging current and the first charging duration when the charging capacity is greater than or equal to the first threshold includes:

[0019] When the charging capacity is greater than or equal to the first threshold, the first preset current is determined as the first charging current, and the first preset time is shortened to obtain the first charging time.

[0020] Optionally, shortening the first preset time to obtain the first charging time includes:

[0021] The target duration is determined based on the charging capacity and the first preset current;

[0022] The first charging time is obtained by shortening the first preset time based on the target time.

[0023] Optionally, after obtaining the battery's charging capacity between the first and second time points, the method further includes:

[0024] If the charging capacity is less than the first threshold, the battery is charged with constant current at the first moment based on the first preset current and the first preset duration of the first charging phase.

[0025] In a second aspect, embodiments of the present invention provide a charging device, comprising:

[0026] The acquisition module is used to acquire the battery charging capacity between a first moment and a second moment, wherein the second moment is before the first moment;

[0027] The adjustment module is used to adjust the first preset current and the first preset duration when the charging capacity is greater than or equal to the first threshold, so as to obtain the first charging current and the first charging duration of the first charging stage, wherein the first charging current is less than the first preset current and / or the first charging duration is less than the first preset duration, the first preset current is the reference charging current of the first charging stage, and the first preset duration is the reference charging duration of the first charging stage.

[0028] The first charging module is used to perform constant current charging on the battery at the first moment based on the first charging current and the first charging duration of the first charging stage.

[0030] Fourthly, embodiments of the present invention provide a readable storage medium for storing a program, which, when executed by a processor, implements the steps of the method described in the first aspect.

[0031] In this embodiment, the battery's charging capacity between a first moment and a second moment is obtained. If the charging capacity is greater than or equal to a first threshold, a first preset current and a first preset duration are adjusted to obtain a first charging current and a first charging duration for the first charging stage. At the first moment, the battery is charged with constant current based on the first charging current and the first charging duration of the first charging stage. Through this method, based on the charging history within a certain period before charging begins, it is determined whether the charging duration and / or charging current of the first charging stage need to be adjusted. This increases the charging current at the start of charging, improves the charging speed, reduces the risk of lithium plating failure, and extends the battery's lifespan.

[0032] To more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments of the present invention will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0034] Figure 2 This is a schematic diagram of the charging device provided in an embodiment of the present invention;

[0035] Figure 3 This is a schematic diagram of the structure of the electronic device provided in an embodiment of the present invention. Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Unless otherwise defined, the technical or scientific terms used in this invention shall have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains. The terms "first," "second," and similar terms used in this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship also changes accordingly.

[0038] This invention provides a charging method that can be applied to scenarios involving constant current charging of batteries. For example... Figure 1 As shown, an embodiment of the present invention provides a charging method, including:

[0039] Step 101: Obtain the battery charging capacity between the first time point and the second time point, where the second time point is before the first time point.

[0040] The first moment is the start time of this charge, and the second moment is any historical moment. The battery's charging capacity between the first and second moments can be used to characterize the battery's historical charging capacity before the start of this charge. The time interval between the first and second moments can be set according to actual needs; for example, the time interval between the first and second moments can be 3 minutes, 5 minutes, or 1 minute, etc.

[0041] Step 102: When the charging capacity is greater than or equal to the first threshold, adjust the first preset current and the first preset duration to obtain the first charging current and the first charging duration of the first charging stage. The first charging current is less than the first preset current and / or the first charging duration is less than the first preset duration. The first preset current is the reference charging current of the first charging stage, and the first preset duration is the reference charging duration of the first charging stage.

[0042] By setting a first threshold value, it is possible to determine whether the battery has experienced the first charging stage in a short period of time based on the charging history before the start of this charging, and then further determine whether the charging process needs to be adjusted.

[0043] The value of the first threshold is not limited here. In specific implementations, the time interval between the first moment and the second moment may be different, and therefore the value of the first threshold may also be different. For example, in some embodiments, the first threshold is greater than the maximum charging capacity of the battery after a preset charging time, that is, the first threshold is greater than the charging capacity after a preset charging time at the initial moment. The preset charging time is related to the time interval between the second moment and the first moment.

[0044] It should be noted that in practical implementation, constant current charging systems typically predefine at least two charging stages, and the reference charging current and reference charging duration for each stage are predetermined (the charging duration of the last charging stage is determined based on actual conditions). For ease of understanding, the following explanation uses three charging stages as an example.

[0045] In this embodiment, the constant current charging system predefines a first charging stage, a second charging stage, and a third charging stage. The first charging stage can also be called the initial charging stage. After the battery is charged with a constant current based on a first preset current for a first preset duration, the system transitions to the second charging stage. After the battery is charged with a constant current based on a second preset current for a second preset duration, the system transitions to the third charging stage. The battery is then charged with a constant current based on a third preset current until charging is complete.

[0046] In this embodiment, determining the first charging current and the first charging duration of the first charging stage when the charging capacity is greater than or equal to the first threshold can also be understood as adjusting the reference charging current and the reference charging duration of the first charging stage when the charging capacity is greater than or equal to the first threshold.

[0047] Optionally, as an optional implementation, step 102 includes:

[0048] When the charging capacity is greater than or equal to the first threshold, the first preset duration is determined as the first charging duration, and the first preset current is reduced to obtain the first charging current.

[0049] Wherein, the first charging current is greater than the second preset current, and the second preset current is the reference charging current for the second charging stage.

[0050] In this embodiment, the second charging stage is adjacent to the first charging stage, and is the next charging stage after the first charging stage. The reference charging current and reference charging duration of the second charging stage are predetermined. To improve battery performance and extend battery life, the charging current gradually decreases in later charging stages as constant current charging continues.

[0051] In this embodiment, the reference charging duration of the first charging stage is not adjusted; only the reference charging current of the first charging stage is adjusted. Through this method, the charging duration of the first charging stage is a first preset duration, and the charging current of the first charging stage is a first charging current.

[0052] It should be understood that the specific method of reducing the first preset current to obtain the first charging current is not limited here. In specific implementation, the first charging current can be any value that is greater than the second preset current and less than the first preset current, and its specific value can be adjusted according to the actual situation and / or the charging capacity.

[0053] In this embodiment, the reference charging time is not adjusted; instead, the first charging current is determined by reducing the first preset current. This method effectively reduces the charging current in the first charging stage, decreasing the initial charging current of the battery during this charge and reducing the duration of continuous high-current charging. This provides some protection for the battery and reduces the risk of lithium plating failure.

[0054] Of course, as another optional implementation, the first charging current can also be equal to the second preset current. In this implementation, it is equivalent to skipping the first charging stage and extending the duration of the second charging stage.

[0055] Optionally, as an optional implementation, step 102 includes:

[0056] When the charging capacity is greater than or equal to the first threshold, the first preset current is determined as the first charging current, and the first preset time is shortened to obtain the first charging time.

[0057] In this embodiment, the reference charging current of the first charging stage is not adjusted; only the reference charging duration of the first charging stage is adjusted. Through this method, the charging current of the first charging stage is a first preset current, and the charging duration of the first charging stage is a first charging duration.

[0058] It should be understood that the specific method for shortening the first preset time to obtain the first charging time is not limited here, and its specific value can be adjusted according to the actual situation and / or the charging capacity. Optionally, in some embodiments, shortening the first preset time to obtain the first charging time includes:

[0059] The target duration is determined based on the charging capacity and the first preset current;

[0060] The first charging time is obtained by shortening the first preset time based on the target time.

[0061] The specific method for determining the target duration based on the charging capacity and the first preset current is not limited here. The target duration can be used to characterize the equivalent duration of the battery in the first charging stage during the previous charging process.

[0062] In practice, the specific method for shortening the first preset duration based on the target duration is not limited here. The duration to be shortened is determined according to the target duration, and the duration to be shortened is shortened based on the first preset duration to obtain the first charging duration, thereby controlling the total duration of the battery in the first charging phase within a short period of time.

[0063] In this embodiment, a target charging time is determined based on the charging capacity and the first preset current; the first charging time is obtained by shortening the first preset time based on the target charging time. In this way, the target charging time determined based on the charging capacity and the first preset current can be used to characterize the equivalent time the battery was in the first charging stage during the previous charging process. Shortening the first preset time based on the target charging time makes the obtained first charging time more reasonable, improving charging speed while reducing the risk of lithium plating failure.

[0064] It should be understood that in some embodiments, the first charging time can be shortened to 0. In this embodiment, it is equivalent to skipping the first charging stage and starting to charge the battery from the second charging stage.

[0065] In this embodiment, the reference charging current is not adjusted; instead, the first charging duration is determined by shortening the first preset duration. This method effectively reduces the charging duration of the first charging phase, shortening the time the battery spends in this phase and reducing the duration of continuous high-current charging. This provides some protection for the battery and reduces the risk of lithium plating failure.

[0066] In the above embodiments, the first charging current is obtained by reducing the first preset current, or the first charging time is obtained by shortening the first preset time, thereby reducing the duration of continuous high-current charging of the battery. This method reduces adjustments to predefined charging regimes while maintaining the flexibility of the charging method, thus improving its convenience.

[0067] Of course, as another optional implementation, the first preset current can be reduced to obtain the first charging current, and the first preset duration can be shortened to obtain the first charging duration, so as to reduce the duration of the battery being continuously in a high-current charging state. The specific implementation method can be found in the foregoing description, and will not be repeated here.

[0068] Step 103: At the first moment, the battery is charged with constant current based on the first charging current and the first charging duration of the first charging phase.

[0069] The first moment is the starting point of battery charging. As an optional implementation, if the first charging duration is not zero, the first charging phase is the initial charging phase of the battery. Constant current charging begins at the first moment; at this time, the battery is in the first charging phase, the charging current is equal to the first charging current, and the duration of the first charging phase is equal to the first charging duration.

[0070] Alternatively, as another optional implementation, step 103 includes:

[0071] When the first charging duration is 0, the first charging stage is skipped and the battery is charged with constant current based on the second preset current and the second preset duration of the second charging stage.

[0072] The second charging phase is adjacent to the first charging phase, the second preset current is the reference charging current of the second charging phase, the second preset duration is the reference charging duration of the second charging phase, and the second preset current is less than the first charging current.

[0073] When the charged capacity is greater than or equal to the first threshold, the first charging time is set to 0. In this case, it can be understood that there is no need to adjust the first preset current, or that the first preset current is set as the first charging current.

[0074] In this embodiment, the charging time of the first charging stage is 0. When charging starts, the first charging stage is skipped and the battery is charged directly from the second charging stage. The battery is charged with constant current based on the second preset current and the second preset duration of the second charging stage. Subsequent charging can be carried out according to the predefined constant current charging stage.

[0075] In this embodiment, when the first charging duration is 0, the first charging stage is skipped, and the battery is charged with constant current based on the second preset current and the second preset duration of the second charging stage. This method eliminates the need to charge the battery based on the first charging current and avoids adjustments to the charging current and / or charging duration of the first charging stage, reducing modifications to the charging stages and improving the feasibility and ease of implementation of this embodiment.

[0076] Optionally, in some embodiments, step 102 includes:

[0077] The average charging rate is calculated based on the charging capacity and the time interval between the first and second moments.

[0078] If the average charging rate is greater than or equal to the second threshold, the first charging duration is determined to be 0, and the first charging current of the first charging stage is determined to be the first preset current.

[0079] The specific value of the second threshold is not limited here. If the average charging rate is greater than or equal to the second threshold, it is considered that the battery has been in the first charging stage for too long in a short period of time. In this case, there is no need to charge the battery in the first charging stage, and the first charging stage can be skipped directly.

[0080] In this embodiment, since the first charging duration is 0, it is equivalent to skipping the first charging stage. In this case, determining the first charging current of the first charging stage as the first preset current is equivalent to not adjusting the reference charging current of the first charging stage, thus improving the ease of operation.

[0081] In this embodiment, the average charging rate is calculated based on the charging capacity and the time interval between the first and second moments. If the average charging rate is greater than or equal to a second threshold, the first charging duration is determined to be 0, and the first charging current of the first charging stage is determined to be the first preset current. In this embodiment, determining whether to skip the first charging stage based on the average charging rate can improve the rationality and accuracy of the determination result.

[0082] Optionally, in some embodiments, after obtaining the battery's charging capacity between the first and second time points, the method further includes:

[0083] If the charging capacity is less than the first threshold, the battery is charged with constant current at the first moment based on the first preset current and the first preset duration of the first charging phase.

[0084] If the charging capacity is less than the first threshold, it can be assumed that the battery is not in the first charging stage for a short period of time. Therefore, it can be charged directly according to the preset constant current charging stage without adjusting the reference charging current and reference charging time of the first charging stage.

[0085] When users frequently plug and unplug the charger, or when the charger has poor contact, it's equivalent to repeatedly starting and stopping the charging process for the battery. For example, if the charger is plugged in for 3 minutes, then unplugged for 3 seconds, and then plugged back in for another 5 minutes, in current technology, each time the battery starts charging, it follows a preset constant current charging phase starting from the first charging stage. This means the battery is actually in the first charging stage for 8 minutes, which could lead to the battery being under high current charging for an extended period, affecting its lifespan and increasing the risk of lithium plating failure.

[0086] In this embodiment, the battery's charging capacity between a first moment and a second moment is obtained; if the charging capacity is greater than or equal to a first threshold, a first charging current and a first charging duration for the first charging phase are determined; and the battery is charged at a constant current based on the first charging current and the first charging duration for the first charging phase at the first moment. Through this method, based on the charging history within a certain period before charging begins, it is determined whether the charging duration and / or charging current of the first charging phase need to be adjusted. This increases the charging current at the start of charging, improves the charging speed, reduces the risk of lithium plating failure, and extends the battery's lifespan.

[0087] For example, if the charging head is plugged in and charged for 3 minutes, then unplugged for 3 seconds and plugged back in, the charging history before the start of this charging can be obtained through the method of this application embodiment. Since the charging capacity is greater than the first threshold, the charging logic of this charging is adjusted. By reducing the charging current of the first charging stage, shortening the charging time of the first charging stage, and skipping the first charging stage, the duration of the battery being in a high-current charging state for a long time is reduced, thereby reducing the risk of lithium plating failure.

[0088] To facilitate understanding, a specific embodiment will be used as an example for illustration below.

[0089] The reference charging time for the first charging stage is preset to 1.5 minutes, and the reference charging current for the first charging stage is 4.7C. The reference charging time for the second charging stage is preset to 2.5 minutes, and the reference charging current for the second charging stage is 3.5C. The reference charging current for the third charging stage is 3C. That is, in this embodiment, when t ≤ 1.5 minutes and U ≤ 4.53V (where 4.53V is the protection voltage), the charging current I = 4.7C; when 1.5 minutes < t ≤ 2.5 minutes and U ≤ 4.53V, the charging current I = 3.5C.

[0090] Before charging begins, the battery's charging capacity between the first and second moments is acquired at the first moment. If the charging capacity is greater than or equal to a first threshold, the first charging current and the first charging duration for the first charging phase are determined.

[0091] In one implementation, the first charging current I1 = 4.7C is maintained, and the charging time of the first charging stage is shortened, resulting in a charging time of less than 1.5 minutes and greater than 0. Charging begins at the first moment based on the first charging current I1 = 4.7C. When the charging time of the first charging stage reaches the first charging duration, the process jumps to the second charging stage. The charging current of the second charging stage satisfies I2 = 3.5C. When the charging time of the second charging stage reaches 2.5 minutes, the process jumps to the third charging stage. The charging current of the third charging stage is I3 = 3C. When the battery voltage rises to 4.53V, the 0.4C stage is cut off.

[0092] In another embodiment, the first charging time is maintained at 1.5 minutes, and the charging current in the first charging stage is reduced, resulting in a charging current in the first charging stage that is less than 4.7C and greater than or equal to 3.5C. Charging is performed based on the first charging current at the first moment. When the charging time of the first charging stage reaches 1.5 minutes, it jumps to the second charging stage. The charging current in the second charging stage satisfies I2 = 3.5C. When the charging time of the second charging stage reaches 2.5 minutes, it jumps to the third charging stage. The charging current in the third charging stage is I3 = 3C. When the battery voltage rises to 4.53V, the 0.4C stage is cut off.

[0093] In another implementation, the charging time of the first charging stage can be set to 0, thus skipping the first charging stage and directly starting charging from the second charging stage at the first moment. The charging current of the second charging stage satisfies I2 = 3.5C. When the charging time of the second charging stage reaches 2.5 minutes, it jumps to the third charging stage. The charging current of the third charging stage is I3 = 3C. When the battery voltage rises to 4.53V, the 0.4C stage is cut off.

[0094] In the first charging stage, the charging current I1 = 4.7C. When the charging time of the first charging stage reaches 1.5 minutes, it switches to the second charging stage. In the second charging stage, the charging current I2 = 3.5C. When the charging time of the second stage reaches 2.5 minutes, it switches to the third charging stage. In the third charging stage, the charging current I3 = 3C. When the battery voltage rises to 4.53V, the 0.4C stage is cut off.

[0095] Please see Figure 2 ,like Figure 2 As shown, this embodiment of the invention also provides a charging device 200, which includes:

[0096] The acquisition module 201 is used to acquire the battery charging capacity between a first time point and a second time point, wherein the second time point is before the first time point;

[0097] The adjustment module 202 is used to adjust the first preset current and the first preset duration when the charging capacity is greater than or equal to the first threshold, so as to obtain the first charging current and the first charging duration of the first charging stage, wherein the first charging current is less than the first preset current and / or the first charging duration is less than the first preset duration, the first preset current is the reference charging current of the first charging stage, and the first preset duration is the reference charging duration of the first charging stage.

[0098] The first charging module 203 is used to perform constant current charging on the battery at the first moment based on the first charging current and the first charging duration of the first charging stage.

[0099] Optionally, the first charging module 203 is specifically used for:

[0100] When the first charging duration is 0, the first charging stage is skipped and the battery is charged with constant current based on the second preset current and the second preset duration of the second charging stage.

[0105] Optionally, the adjustment module 202 is specifically used for:

[0106] When the charging capacity is greater than or equal to the first threshold, the first preset duration is determined as the first charging duration, and the first preset current is reduced to obtain the first charging current.

Through this method, based on the charging history within a certain period before charging begins, it determines whether the charging duration and / or charging current of the first charging stage need to be adjusted. This increases the charging current at the start of charging, improves the charging speed, reduces the risk of lithium plating failure, and extends the battery's lifespan.
