Detailed ways

Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the invention. Rather, they are merely examples of apparatus and methods consistent with aspects of the invention as detailed in the appended claims.

FIG. 1 is a flow chart of a battery control method according to an exemplary embodiment. The battery control method is used in a terminal, and the battery of the terminal includes at least two cells. Referring to FIG. 1 , the battery control method may include the following steps.

Step S110, determine that the terminal is in a resting state, where in the resting state the terminal is in a non-charging state and a non-using state;

Step S120: Control the terminal to enter a battery balancing state to balance the power of at least two battery cells.

In step S110, regarding the non-charging state, the terminal may determine whether the terminal is in the non-charging state by detecting whether the charger is in place. If the terminal detects that the charger is not in place, it means that the terminal is in a non-charging state.

Regarding the non-use state, the terminal can set the first setting condition. The first setting condition refers to the condition used to determine that the terminal is in a non-use state. The terminal may determine whether the terminal is in a non-use state by determining whether the first set condition is met. If it is determined that the terminal meets the first set condition, it means that the terminal is in a non-use state.

The first setting condition may be set before the terminal leaves the factory, or may be set after the terminal leaves the factory, and there is no limit to this. Moreover, after the first set condition is set, it can also be modified later to better meet the needs of the user. The first setting condition can be set according to the actual situation, and there is no limitation on this. For example, if it is determined that the duration of the terminal not receiving touch information is greater than or equal to 10 minutes, it can be determined that the terminal meets the first set condition.

In this step, if it is determined that the charger is not in place and the terminal meets the first set condition, it can be determined that the terminal is in a resting state.

In step S120, the terminal can enter the battery balancing state by controlling the balancing circuit to be turned on, thereby balancing the power of each cell in the battery, or the terminal can enter the battery balancing state by other means, thereby balancing the power of each cell in the battery. The amount of electricity is not limited.

Among them, when the battery includes two cells, after the terminal enters the battery balancing state, the power of the two cells can be balanced so that the series voltage difference between the two cells meets the requirements. When the battery includes more than two cells, after the terminal enters the battery balancing state, the power of the above two or more cells can be balanced so that the series voltage difference between any two cells meets the requirements.

In this method, when the terminal is in a resting state, the terminal can also be made to enter the battery balancing state, thereby better avoiding the self-discharge of the battery in the terminal and the static power consumption discharge of the terminal, resulting in a relatively large gap between the two strings of cells. The large series voltage difference can effectively slow down the aging rate of the cells in the battery, extend the overall service life of the battery, and improve the user experience.

In an exemplary embodiment, a battery control method is provided and applied to a terminal. In this method, determining that the terminal meets the first set condition may include at least one of the following:

Condition 1, determine that the current moment is within the first set time interval;

Condition 2: It is determined that the power consumption of the terminal is less than or equal to the first set power consumption;

Condition 3: It is determined that the duration of the terminal in the set state is greater than or equal to the first set duration.

In condition 1, according to the user's usage habits, the user generally does not use the terminal within a specific time interval. Therefore, the above-mentioned specific time interval can be set as the first set time interval. The first set time interval may be a nighttime sleep time interval, a lunch break time interval, or other time intervals, which is not limited. The first set time interval may be determined by the terminal through intelligent learning, or may be preset in advance, and there is no limit to this.

In some embodiments, the first set time interval is a night sleep time interval. The terminal is equipped with an intelligent learning function. When the terminal detects that within 7 consecutive days, between the time interval 22:00 and 8:00 the next day, the charger has been in place for more than or equal to 5 hours for more than or equal to 3 days. , it means that the user of this terminal has the habit of sleeping and charging at night. The terminal's intelligent learning function determines the night sleep time interval. For example, the nighttime sleep time interval determined by intelligent learning is from 23:00 to 6:00 the next day, then the first set time interval is from 23:00 to 6:00 the next day. In this implementation, if it is determined that the current time is between the time interval 23:00 and 6:00 the next day, it means that the terminal satisfies condition 1.

In some embodiments, if the user is accustomed to taking a lunch break from 12:30 to 13:30, the user can set the first set time interval to 12:30 to 13:30. In this implementation, if it is determined that the current time is between 12:30 and 13:30, it means that the terminal meets condition 1.

In condition 2, when the terminal is not in use, the power consumption of the terminal is generally low. Therefore, it can be determined whether the terminal is in a non-use state by setting the first set power consumption. If it is determined that the current power consumption of the terminal is less than or equal to the first set power consumption, the terminal is considered to meet condition 2.

The first set power consumption can be set according to the actual situation, and the specific value is not limited. The first set power consumption may be set before the terminal leaves the factory, or may be set after the terminal leaves the factory, and this is not limited. In addition, after the first power consumption setting is completed, it can be modified later to better meet the user's needs.

In some implementations, the first set power consumption is A. If the current power consumption of the terminal is less than or equal to the first set power consumption A, it means that the terminal meets condition 2. If the current power consumption of the terminal is greater than the first set power consumption A, it means that the terminal does not meet condition 2. Among them, the first set power consumption A can be set according to actual needs, and there is no limitation on this. For example, the first set power consumption A may be 20mA to 30mA.

In Condition 3, the set state may include a screen-off state, a state in which the terminal detects manipulation information, or other states that may indicate that the terminal is in a non-use state, and is not limited to this. The control information may include touch information or key information, which is not limited.

The first set duration may be set before the terminal leaves the factory, or may be set after the terminal leaves the factory, and there is no limit to this. In addition, after the first set duration is set, it can be modified later to better meet the needs of users. The first set duration can be set according to the actual situation, and the specific value is not limited.

In some embodiments, the set state includes a screen-enabled state, and the first set duration is B. If the duration of the terminal in the screen-off state is greater than or equal to the first set duration B, it means that the terminal meets condition 3. If the duration of the terminal in the screen-off state is less than the first set duration B, it means that the terminal does not meet condition 3. Among them, the first set duration B can be set according to actual needs, and is not limited to this. For example, the first set time period B may be 30 minutes.

It should be noted that determining that the terminal satisfies the first setting condition may include any one of the above three conditions, any two of the above three conditions at the same time, or may include the above three conditions at the same time.

In some implementations, it is determined that the terminal meets the first set condition, including the above three conditions. The first set time interval is the night sleep time interval obtained by intelligent learning from 23:00 to 6:00 the next day. The first set power consumption is A, the first set duration is B, and the set state is the screen off state. In this implementation, if it is determined that the current time is between 23:00 and 6:00 the next day, and it is determined that the current power consumption of the terminal is less than or equal to the first set power consumption A, and it is determined that the terminal is in the screen-off state for If the duration is greater than or equal to the first set duration B, it is determined that the terminal meets the first set condition. Otherwise, it is determined that the terminal does not meet the first setting condition.

In this method, through the setting of the above conditions 1, 2 and/or 3, it can be better determined that the terminal meets the first setting condition, thereby well determining that the terminal is in a non-use state. In order to determine that the terminal is in a resting state Provides reliable support to further enhance user experience.

In an exemplary embodiment, a battery control method is provided and applied to a terminal. In this method, after determining that the terminal is in a quiet state, it may include:

Step S310: Increase the set discharge current threshold by a set value so that the battery's fuel gauge enters a rest mode.

Among them, the fuel gauge is generally set with a discharge current threshold for entering the rest mode, which is recorded as the set discharge current threshold. When the fuel gauge detects that the battery's discharge current is less than or equal to the set discharge current threshold, it can enter the rest mode. According to the characteristics of the battery, generally when the fuel gauge enters the rest mode, the terminal can control the fuel gauge to start the cell balancing function, so that the terminal enters the battery balancing state, and then more accurately measures the power of each battery cell. Balanced processing.

Among them, the set current threshold and set value can be determined according to the actual situation, and their specific data are not limited. For example, the set current threshold can be 60mA, and the set value can be 80mA to 100mA.

In this method, after it is determined that the terminal is in a static state, before controlling the terminal to enter the battery balancing state, the set discharge current value can be increased to the set value, that is, the original set discharge current value is increased so that the new The set discharge current threshold is greater than or equal to the current discharge current of the battery, causing the fuel gauge to enter rest mode. After the battery gauge enters rest mode, the terminal can be controlled to enter the battery balancing state, achieving a more accurate balancing effect and improving the user experience.

In an exemplary embodiment, a battery control method is provided and applied to a terminal. In this method, after the control terminal enters the battery balancing state, it may include:

S410. If it is determined that the series voltage difference between at least two cells is less than or equal to the set voltage difference, the control terminal exits the battery balancing state.

Among them, the set pressure difference can be set before the terminal leaves the factory, or it can be set after the terminal leaves the factory, and there is no limit to this. In addition, after the set pressure difference is set, it can be modified later to better meet the user's needs. The set pressure difference can be set according to the actual situation, and the specific value is not limited. The set voltage difference generally refers to the allowable series voltage difference between the cells of the battery. It should be noted that the set pressure difference can be determined according to the actual situation and is not limited. For example, the set voltage difference may be 3mV to 5mV.

Wherein, after the terminal is in the battery balancing state, it can detect the series voltage difference between at least two cells in real time or periodically, and determine the size of the series voltage difference and the set voltage difference. If it is determined that the series voltage difference is greater than the set voltage difference, it means that there is still a large series voltage difference between the cells, and the battery will continue to be in a balanced state. If it is determined that the series voltage difference is less than or equal to the set voltage difference, it means that the series voltage difference between cells is small enough, and the terminal can be controlled to exit the battery balancing state.

It should be noted that when the battery includes two cells and the terminal is in the battery balancing state, if it is determined that the series voltage difference between the two cells is less than or equal to the set voltage difference, the terminal can be controlled to exit the battery balancing state. state. Otherwise, the control terminal continues to be in the battery balancing state to continue balancing the power and voltage between the two cells.

When the battery includes more than two cells, when the terminal is in the battery balancing state, if it is determined that the series voltage difference between any two cells is less than or equal to the set voltage difference, the terminal can be controlled to exit the battery balancing state. Otherwise, the control terminal continues to be in the battery balancing state to continue to balance the power and voltage between cells with large series voltage differences, thereby better achieving the battery balancing effect, better avoiding cell aging, and better extending the battery life. overall lifespan.

In this method, when the terminal is in the battery balancing state, when the series voltage difference between the battery cells is less than or equal to the set voltage difference, the terminal can be controlled to exit the battery balancing state to avoid unnecessary battery balancing processing. Further improve the user experience.

In an exemplary embodiment, a battery control method is provided and applied to a terminal. This method may include:

Step S410, determine that the terminal is in the charging state, and determine that the terminal meets the second setting condition;

Step S420: The control terminal enters maintenance mode.

In step S410, regarding the charging state, the terminal can determine whether the terminal is in a non-charging state by detecting whether the charger is in place. If the terminal detects that the charger is in place, it means that the terminal is in charging state.

In this step, the second setting condition refers to the condition used to determine that the terminal is in a non-use state. The second setting condition and the first setting condition may be the same or different, and there is no limitation on this. If the terminal determines that it meets the second setting condition, it can determine that the terminal is in a non-use state.

The second setting condition may be set before the terminal leaves the factory, or may be set after the terminal leaves the factory, and there is no limit to this. Moreover, after the second set condition is set, it can also be modified later to better meet the user's needs. The second setting condition can be set according to the actual situation, and there is no limitation on this.

Wherein, the second setting condition may include at least one of the following:

Condition a determines that the current moment is located in the second set time interval;

Condition b, it is determined that the power consumption of the terminal is less than or equal to the second set power consumption;

Condition c determines that the duration of the terminal in the set state is greater than or equal to the second set duration.

In condition a, the setting of the second set time interval may refer to the first set time interval, which will not be described again. It should be noted that the second set time interval may be the same as the first set time interval, or may be different from the first set time interval, which is not limited. For example, the second set time interval may be the user's night sleep time interval: 23:00 of the current day to 6:00 of the next day.

In condition b, when the terminal is not in use, the power consumption of the terminal is generally low. Therefore, it can be determined whether the terminal is in a non-use state by setting the second set power consumption. If it is determined that the current power consumption of the terminal is less than or equal to the second set power consumption, the terminal is considered to meet condition b.

The setting method of the second set power consumption may refer to the first set power consumption, which will not be described again. In addition, the second set power consumption may be the same as the first set power consumption, or may be different from the first set power consumption, and this is not limited.

It should be noted that when the terminal is in a non-use state, the power consumption of the terminal in the charging state is generally greater than the power consumption in the non-charging state. Therefore, the second set power consumption can be set to be greater than or equal to the first set power consumption. For example, the first set power consumption may be 20mA to 30mA, and the second set power consumption may be 30mA to 50mA.

In condition c, the set state may include a screen-off state, a state in which the terminal detects control information, or other states that can indicate that the terminal is in a non-use state, and is not limited to this. The control information may include touch information or key information, which is not limited.

The setting method of the second set duration may refer to the first set duration, which will not be described again. In addition, the second set time length may be the same as the first set time length, or may be different from the first set time length, and this is not limited.

For example, the second set duration is the same as the first set duration, and both can be 30 minutes.

It should be noted that determining that the terminal satisfies the second setting condition may include any one of the above three conditions, any two of the above three conditions at the same time, or may include the above three conditions at the same time.

In step S420, in the maintenance mode, if it is determined that the state of charge of the battery reaches a set percentage, the terminal is controlled to enter a battery balancing state to balance the power of at least two cells.

The set percentage may be set before the terminal leaves the factory, or may be set after the terminal leaves the factory, and there is no limit to this. Moreover, after the setting percentage is completed, it can be modified later to better meet the user's needs. The set percentage can be set according to the actual situation and is not limited. For example, the set percentage may be 60% to 80%.

In some embodiments, the battery of the battery control method terminal may include two cells. In this embodiment, the terminal can determine the user's night sleep time interval from 23:00 to 6:00 the next day through intelligent learning, and use the night sleep time interval as the first set time interval.

Among them, if the processor of the terminal determines that the charger is not in place, it means that the terminal is in a non-charging state.

When the processor determines that the charger is not in place, the terminal's processor can continue to determine whether the current time is in the time interval from 23:00 to 6:00 the next day, and determine whether the current power consumption of the terminal is less than or equal to 1. Set the power consumption A, and determine whether the duration of the terminal in the screen-off state is greater than or equal to the first set duration B.

If it is determined that the current time is in the time interval from 23:00 to 6:00 the next day, and it is determined that the current power consumption of the terminal is less than or equal to the first set power consumption A, and it is determined that the duration of the terminal in the screen-off state is greater than or equal to The first set time period B indicates that the terminal is in a non-use state. Therefore, since it has been determined that the terminal is in a non-charging state and a non-use state, it can be determined that the terminal is in a resting state.

After determining that the terminal is in a static state, the set discharge current threshold can be increased by the set value C, so that the discharge current detected by the battery's fuel gauge is less than or equal to the new set discharge current threshold, thereby causing the fuel gauge to enter Rest mode. After the fuel gauge enters the rest mode, the terminal can be controlled to enter the battery balancing state to balance the power of the two cells in the battery.

In addition, when the processor determines that the charger is in place, it means that the terminal is in a charging state. In this case, the processor of the terminal can continue to determine whether the current time is in the time interval from 23:00 to 6:00 the next day, and determine whether the current power consumption of the terminal is less than or equal to the first set power consumption A', And determine whether the duration of the terminal in the screen-off state is greater than or equal to the first set duration B. Among them, the first set power consumption A' is generally greater than or equal to the first set power consumption A. Among them, the first set power consumption A' can be set according to the actual situation, and is not limited. For example, the first set power consumption A' may be 30mA to 50mA.

If it is determined that the current time is in the time interval from 23:00 to 6:00 the next day, and it is determined that the current power consumption of the terminal is less than or equal to the first set power consumption A', and it is determined that the duration of the terminal in the screen-off state is longer than or If it is equal to the first set duration B, it means that the terminal is in a non-use state. Therefore, since it has been determined that the terminal is in the charging state and the non-use state, it can be determined that the terminal is in the static charging state.

After it is determined that the terminal is in a static charging state, the terminal can be controlled to enter the maintenance mode, so that the battery's state of charge (SOC) stops charging to a set percentage (for example, 70%), and then the fuel gauge enters the rest mode. After the fuel gauge enters the rest mode, the terminal can be controlled to enter the battery balancing state to balance the power of the two cells in the battery.

Among them, when the terminal is in the battery balancing state, if it is determined that the series voltage difference between the two cells is less than or equal to the set voltage difference D, it means that the balance of power and voltage between the two cells has been completed. The control terminal exits the battery balancing state.

This method can not only ensure that the terminal is in a static charging state (that is, the terminal is in a charging state and a non-use state), but also control the terminal to enter a battery balancing state, and can also ensure that the terminal is in a static state (that is, the terminal is in a non-charging state and a non-use state). ), the control terminal enters the battery balancing state. This method can better balance the power and voltage between the cells in the battery, thereby better slowing down the aging of the cells, better extending the overall service life of the battery, and improving the user experience.
