Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

It should be noted that the terms "first," "second," and the like in the description, the claims, and the description of the drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

The first embodiment is as follows:

in order to solve the problem that when a rechargeable battery is charged, the rechargeable battery is directly charged to full capacity, and when the charging cannot be stopped in time, the rechargeable battery is in a high-potential state for a long time, and the service life of the battery is reduced, an embodiment of the present invention provides a charging method, as shown in fig. 1, including:

s101: and monitoring the electric quantity of the battery to be charged when the battery to be charged is determined to be connected with the charging power supply.

S102: and controlling the electric quantity of the battery to be charged not to be less than a second electric quantity threshold value and not to exceed a first electric quantity threshold value according to the monitoring result.

It should be noted that, before step S102, it may also be determined that the charging of this time is charging longer than a preset time period, where the "charging of this time is charging longer than the preset time period" means that the charging time period of this time is longer than the preset time period, and optionally, the preset time period may be 10 hours, 9 hours, 3 hours, 4 hours, and the like. Specifically, the terminal including the battery to be charged may pre-determine the charging time of the current charging, for example, when it is determined that the battery to be charged is connected to the charging power supply, the terminal including the battery to be charged may obtain historical behavior operation data of the user on the terminal, and pre-determine the charging time of the current charging based on the historical behavior operation data, for example, the terminal may determine a most likely time point when the user falls asleep and a most likely time point when the terminal starts to sleep according to the historical behavior operation data, if the current time point when the battery to be charged is connected to the charging power supply is right after the time point when the user falls asleep, it may be determined that the user is falling asleep, and pre-determine the charging time of the current charging as a time difference between the time point when the user starts to sleep and the current time point, if the time difference is greater than the preset time, it should be stated that the current charging is, when the terminal determines the getting-up time point, the terminal can also determine in combination with an alarm clock set by a user. For example, the set alarm clock ringing time can be used as the waking time point. In some embodiments, after the battery to be charged is connected to the charging power supply, a charging end time input interface may pop up on a display interface of the terminal including the battery to be charged, and the user may input the time for pulling out the battery to be charged from the charging power supply based on the charging end time input interface, for example, the user may input the time for pulling out the battery to be charged from the charging power supply on the terminal according to the time for getting up, the time for going out, and the like, and the terminal may determine the charging duration based on the time input by the user and the time for connecting the battery to be charged to the charging power supply. It should also be noted that, when it is determined that the current charging is not the charging longer than the preset time, the battery to be charged may be charged in a normal charging manner, without limiting the electric quantity of the battery to be charged, and the electric quantity of the battery to be charged is directly fully charged.

In the above embodiment, a scheme for limiting the charging electric quantity of the battery to be charged after determining that the charging time of the current charging is longer than the preset time is introduced. It should be noted that, in some other embodiments, whether the limitation of the charging capacity of the battery to be charged is needed may be determined directly according to the time point when the battery to be charged is connected to the charging power supply. For example, when the time point of connecting the battery to be charged to the charging power supply is determined to be the time point within the preset time range, step S102 is executed again to limit the charging electric quantity of the battery to be charged, where the preset time range may be a time range from nine pm to eight am, when the user connects the battery to be charged to the charging power supply within the time range, it indicates that the user is likely to fall asleep, and at this time, limiting the charging electric quantity of the battery to be charged can prevent the user from damaging the battery to be charged because the user cannot timely unplug the battery to be charged during sleep, but the preset time range may also be flexibly set by developers, and may also support user-defined setting.

The second electric quantity threshold in step S102 is smaller than the first electric quantity threshold, and the first electric quantity threshold is smaller than the electric quantity value of the battery to be charged when the battery is fully charged.

It should be noted that, in some embodiments, the second charge threshold and the first charge threshold may be set in advance by a developer, for example, the second charge threshold may be set based on a standard capacity of the battery to be charged, for example, a product of the standard capacity of the battery to be charged and x may be used as the first charge threshold, and a product of the standard capacity of the battery to be charged and y may be used as the second charge threshold, where x may be any one of 65% to 80%, and y may be any one of 40% to 55%. In still other embodiments, the first and second charge thresholds may be fixed after the setting is complete.

Of course, in other embodiments, the magnitudes of the first power threshold and the second power threshold at the current time may be determined before step S102. Specifically, the current charge state parameter of the battery to be charged may be obtained through the electricity meter, the magnitudes of the first electricity threshold and the second electricity threshold are determined according to the charge state parameter, and step S102 is executed after the magnitudes of the first electricity threshold and the second electricity threshold are determined, it should be understood that, at this time, the magnitudes of the first electricity threshold and the second electricity threshold in step S102 are also the magnitudes of the second electricity threshold of the first electricity threshold determined according to the charge state parameter before this step. For such an example, the charging state parameter of the battery to be charged may be changed at different charging times, so that the first power threshold and the second power threshold may also be changed correspondingly.

The charge state parameter in the present embodiment includes, but is not limited to, at least one of the following parameters: the battery management system comprises a battery real capacity parameter, a battery aging degree parameter, a current limiting parameter, a power consumption parameter and a charging current parameter.

In a first example, the first electric quantity threshold and the second electric quantity threshold may be determined according to a battery real capacity parameter, where the battery real capacity parameter represents an electric quantity value when the battery is fully charged, it should be understood that, as the battery is continuously used, the real capacity of the battery is often lower than a standard capacity and may be continuously reduced, in this example, a first proportional parameter a and a second proportional parameter b may be preset on a terminal including the battery to be charged, where 0< b < a <1, and the specific step of determining the magnitudes of the first electric quantity threshold and the second electric quantity threshold according to the charging state parameter may be: the product of the battery real capacity parameter and the preset first proportional parameter a is used as a first electric quantity threshold, and the product of the battery real capacity parameter and the preset second proportional parameter b is used as a second electric quantity threshold, where the preset first proportional parameter and the second proportional parameter in this embodiment may be arbitrarily set by a developer, for example, may be as follows: a is more than or equal to 65 percent and less than or equal to 80 percent, b is more than or equal to 40 percent and less than or equal to 55 percent. Preferably, the first proportional parameter in this embodiment may be 70%, and the second proportional parameter may be 50%, so that when the electric quantity of the battery to be charged is controlled between the first electric quantity threshold and the second electric quantity threshold, it may be ensured that the aging speed of the battery is slow at this time, and the service life of the battery is prolonged.

In the second example, the magnitudes of the first electric quantity threshold and the second electric quantity threshold may be determined according to the battery aging degree parameter, and in general, the battery aging degree parameter is a ratio of the actual battery capacity to the standard battery capacity.

In a third example, the first electric quantity threshold and the second electric quantity threshold may be determined according to a power consumption parameter, where the power consumption parameter may represent a power consumption situation of a terminal including the battery to be charged, and the larger the value of the power consumption situation, the larger the power consumption situation, so when the power consumption parameter is larger, the larger the values of the first electric quantity threshold and the second electric quantity threshold determined are than the values of the first electric quantity threshold and the second electric quantity threshold determined when the power consumption parameter is smaller. Specifically, a correspondence table between each power consumption range and the electric quantity threshold may be preset on a terminal including the battery to be charged, where the correspondence table includes a correspondence between each power consumption range and each first electric quantity threshold and each second electric quantity threshold, each power consumption range has a fixed first electric quantity threshold and a fixed second electric quantity threshold corresponding thereto, a size of the first electric quantity threshold corresponding to the high power consumption range is larger than a size of the first electric quantity threshold corresponding to the low power consumption range, and a size of the second electric quantity threshold corresponding to the high power consumption range is larger than a size of the second electric quantity threshold corresponding to the low power consumption range. In this example, when the terminal acquires the power consumption parameter of the battery to be charged, the acquired power consumption parameter may be substituted into the corresponding relationship table between the power consumption range and the electric quantity threshold value for matching, so as to match a first electric quantity threshold value and a second electric quantity threshold value corresponding to the current power consumption parameter.

In a fourth example, the magnitudes of the first electric quantity threshold and the second electric quantity threshold may be determined according to the charging current parameter, at this time, similarly, a corresponding relation table between each charging current range and the electric quantity threshold may be preset on a terminal including the battery to be charged, each charging current range has a corresponding fixed first electric quantity threshold and second electric quantity threshold, and since the smaller the charging current is, it is described that the electric quantity consumption speed of the terminal may be greater than the electric quantity charging speed of the terminal, the magnitude of the first electric quantity threshold corresponding to the high charging current range in this example is smaller than the magnitude of the first electric quantity threshold corresponding to the low charging current range, and meanwhile, the magnitude of the second electric quantity threshold corresponding to the high charging current range is smaller than the magnitude of the second electric quantity threshold corresponding to the low charging range. In this example, when the terminal obtains the charging current parameter of the battery to be charged, the obtained charging current parameter may be substituted into the corresponding relationship table between the charging current range and the electric quantity threshold for matching, so as to match a first electric quantity threshold and a second electric quantity threshold corresponding to the current charging current parameter.

In a fifth example, the first and second charge thresholds may be sized according to a real battery capacity parameter and a power consumption parameter. Specifically, a corresponding relation table between each power consumption range and an electric quantity threshold value can be preset on a terminal containing the battery to be charged, the corresponding relation table comprises corresponding relations of power consumption ranges and strategies for calculating the sizes of the first electric quantity threshold value and the second electric quantity threshold value, each power consumption range is provided with the strategy for calculating the first electric quantity threshold value and the second electric quantity threshold value, the strategy for calculating the first electric quantity threshold value is to multiply a preset first proportion parameter and the real capacity of the battery, the strategy for calculating the second electric quantity threshold value is to multiply a preset second proportion parameter and the real capacity parameter of the battery, each power consumption range is provided with the corresponding first proportion parameter and second proportion parameter, the first proportion parameter corresponding to the high power consumption range is larger than the first proportion parameter corresponding to the low power consumption range, and the second proportion parameter corresponding to the high power consumption range is larger than the second proportion parameter corresponding to the low power consumption range. In this example, as shown in table one below, assuming that the power consumption parameter of the battery to be charged is P, as can be seen from table one, the power consumption range is from low to high from left to right, and 65% of the first proportional parameter corresponding to the lowest power consumption range is smaller than the first proportional parameters corresponding to the remaining high power consumption ranges, such as 70% and 75%; the second proportion parameter 45% corresponding to the lowest power consumption range is smaller than the second proportion parameters such as 50% and 55% corresponding to the rest high power consumption ranges;

watch 1

In this example, when the terminal acquires the power consumption parameter of the battery to be charged, the acquired power consumption parameter may be substituted into the corresponding relation table between the power consumption parameter range and the electric quantity threshold value to perform matching, a policy for calculating the first electric quantity threshold value and the second electric quantity threshold value corresponding to the current power consumption parameter is obtained by matching, and then the acquired current battery real capacity parameter is multiplied by the first proportional parameter and the second proportional parameter respectively to obtain the size of the first electric quantity threshold value and the size of the second electric quantity threshold value.

It should be noted that the examples listed herein are merely illustrative of how the first and second charge amount thresholds are determined, and are not limiting on the manner in which the first and second charge amount thresholds are determined, and in other embodiments, the first and second charge amount thresholds may be determined in combination with the various charge state parameters described above.

In this embodiment, the electric quantity of the battery to be charged may be controlled not to be less than the second electric quantity threshold and not to exceed the first electric quantity threshold by the following method:

and stopping charging the battery to be charged when the monitored electric quantity of the battery to be charged is not less than the first electric quantity threshold value, and recovering the charging of the battery to be charged when the monitored electric quantity of the battery to be charged is not more than the second electric quantity threshold value.

It should be noted that, for one charging process of the same battery to be charged, the first electric quantity threshold and the second electric quantity threshold in the charging process may be dynamically changed, for example, in the process of controlling the electric quantity of the battery to be charged between the first electric quantity threshold M and the second electric quantity threshold N, the charging state parameter of the battery to be charged may be obtained at every preset time interval T1, the magnitudes of the first electric quantity threshold and the second electric quantity threshold are re-determined according to the newly obtained charging state parameter, if the magnitudes of the first electric quantity threshold and the second electric quantity threshold determined here are different from the previously determined first electric quantity threshold M and second electric quantity threshold N, the magnitudes of the first electric quantity threshold and the second electric quantity threshold need to be updated to the newly determined values, and the updated values are used as a comparison reference, for example, the newly determined first electric quantity threshold is P, the second charge threshold is Q, the charge of the battery to be charged should be controlled between P and Q. The preset time interval T1 in the present embodiment can be arbitrarily set by the developer, and can be set to 5 minutes, 10 minutes, etc,

S103: and judging whether the battery to be charged currently meets a preset unlimited direct charging condition, if so, turning to S104, and otherwise, turning to S102.

It should be noted that, in the process of controlling the electric quantity of the battery to be charged between the first electric quantity threshold and the second electric quantity threshold, the determining process may be performed once every preset time interval T2, T2 in this embodiment may be different from T1 mentioned above, or may be the same, it is to be noted that, in order to improve the working efficiency of the processor, when T2 and T1 are the same, it is preferable that the determining process be performed first, and when it is determined that the battery to be charged does not currently satisfy the preset unlimited direct charging condition, the first electric quantity threshold and the second electric quantity threshold are determined again.

The unlimited direct charging condition in this embodiment refers to a condition that the electric quantity of the battery to be charged is not limited, and the battery to be charged is directly and normally charged, and this condition can be flexibly set by a developer.

In an embodiment, the process of determining whether the battery to be charged currently satisfies the preset unlimited direct charging condition may be as shown in fig. 2, and includes:

s21: and acquiring historical behavior operation data of the user on the terminal containing the battery to be charged.

S22: and determining a charging stopping time point for stopping charging the battery to be charged according to the historical behavior operation data.

The terminal in this embodiment can predict the charging stop time point when the user stops charging by learning the habit of the user. The historical behavior operation data of the user acquired in this embodiment includes, but is not limited to, the following data:

the user checks the time of the mobile phone for the first time in the morning, such as the time of lighting a screen for the first time, the time of unplugging a charger and the like; if the user sets the alarm clock in the morning, the time set by the alarm clock can be acquired.

The terminal may make a determination in connection with whether the day is a working day, a holiday, what season, etc., when determining the point of time to stop charging from the historical behavior operation data.

It should be noted that in other embodiments, the charging stop time point may also be input by the user.

S23: and when the charging stopping time point is reached and the battery to be charged is in a full-electric-quantity state, correspondingly entering a target time point of a state without limiting the electric quantity of the battery to be charged according to the charging stopping time point and the current charging state parameters of the battery to be charged.

Specifically, the target time point may be calculated from the stop charging time point, the current electric quantity value of the battery to be charged, the current charging current, the terminal power consumption, the battery charging curve, and the like. When the target time point is reached, the terminal enters a state of not limiting the electric quantity of the battery to be charged, and the battery to be charged can be normally charged, so that when the charging stop time is reached, the electric quantity of the battery to be charged can reach the full electric quantity, optionally, in step S23, when the charging stop time point is reached according to the charging stop time point and the current charging state parameter of the battery to be charged, the battery to be charged just reaches the target time point of entering the state of not limiting the electric quantity of the battery to be charged when the full electric quantity state is just reached, so that when the charging stop time is reached, the electric quantity of the battery to be charged just can reach the full electric quantity, the time of the battery at high potential is greatly reduced, and the service life of the battery is prolonged.

S24: and judging whether the current charging time is the target time point, if so, turning to S25, and otherwise, turning to S26.

S25: and judging that the preset unlimited direct charging condition is currently met.

S26: and controlling the electric quantity of the battery to be charged between the first electric quantity threshold value and the second electric quantity threshold value.

In another embodiment, the process of determining whether the battery to be charged currently satisfies the preset unlimited direct charging condition may be as shown in fig. 3, and includes:

s31: and acquiring the current power consumption of the terminal containing the battery to be charged.

S32: and judging whether the power consumption is larger than a preset power consumption threshold, if so, turning to S33, and otherwise, turning to S34.

S33: and judging that the battery to be charged currently meets the preset unlimited direct charging condition.

S34: and judging that the battery to be charged does not meet the preset unlimited direct charging condition currently.

In this example, when the power consumption of the terminal is large, the control terminal enters a state in which the electric quantity of the battery to be charged is not limited, so that the electric quantity of the battery is ensured to be sufficient, and low-power shutdown caused by a high-power state is avoided.

S104: the electric quantity of the battery to be charged is not limited, and the battery to be charged is directly charged.

The step of not limiting the electric quantity of the battery to be charged in this embodiment means that the electric quantity of the battery to be charged is not limited between the first electric quantity threshold and the second electric quantity threshold, but the battery to be charged is directly and normally charged.

The charging method provided by the embodiment of the invention monitors the electric quantity of the battery to be charged when the battery to be charged is determined to be connected with the charging power supply, controls the electric quantity of the battery to be charged not to be smaller than a second electric quantity threshold value and not to exceed a first electric quantity threshold value according to the monitoring result, wherein the second electric quantity threshold value is smaller than the first electric quantity threshold value, and the first electric quantity threshold value is smaller than the electric quantity value of the battery to be charged when the current full electric quantity of the battery to be charged is determined, and when the battery to be charged is determined to meet the preset unlimited direct charging condition, the electric quantity of the battery to be charged is not limited, and the battery to be charged is directly charged. Thereby reducing the aging speed of the battery and increasing the service life of the battery.

Example two:

Specifically, the long-time charging determining module 54 may pre-determine the charging time of the current charging, for example, when it is determined that the battery to be charged is connected to the charging power supply, the long-time charging determining module 54 may obtain historical behavior operation data of the user on the terminal, and pre-determine the charging time of the current charging based on the historical behavior operation data, for example, the long-time charging determining module 54 may determine a most likely time point when the user falls asleep and a time point when the user gets up according to the historical behavior operation data, if the current time point when the battery to be charged is connected to the charging power supply is right after the time point when the user falls asleep, it may be determined that the user is falling asleep, and pre-determine the charging time of the current charging as a time difference between the time point when the user comes up and the current time point, if the time difference is greater than the preset time, it may be determined that the current, the long time charging determination module 54 may also perform the determination in combination with an alarm clock set by the user when determining the waking time point.

For example, when it is determined that the time point of connecting the battery to be charged to the charging power supply is the time point within the preset time range, the power control module 52 may be notified to control the power of the battery to be charged, where the preset time range may be a time range from nine pm to eight am, and when the user connects the battery to be charged to the charging power supply within the time range, it indicates that the user is likely to fall asleep, and at this time, the limitation on the charging power of the battery to be charged may prevent the user from damaging the battery to be charged because the user cannot timely unplug the battery to be charged during sleep.

Preferably, the power threshold determining module 55 may determine the magnitudes of the first power threshold and the second power threshold according to a battery real capacity parameter, where the battery real capacity parameter represents the magnitude of the power value when the battery is fully charged, it should be understood that as the battery is continuously used, the real capacity of the battery is often lower than the standard capacity and is continuously decreased, in this example, a first proportional parameter a and a second proportional parameter b may be preset on the terminal including the battery to be charged, where 0< b < a <1, the power threshold determining module 55 may use a product of the battery real capacity parameter and a preset first proportional parameter a as the first power threshold, and use a product of the battery real capacity parameter and a preset second proportional parameter b as the second power threshold, where the preset first proportional parameter and the second proportional parameter in this embodiment may be arbitrarily set by a developer, for example, the following values may be taken: a is more than or equal to 65 percent and less than or equal to 80 percent, b is more than or equal to 40 percent and less than or equal to 55 percent.

Specifically, the target time point may be calculated from the stop charging time point, the current electric quantity value of the battery to be charged, the current charging current, the terminal power consumption, the battery charging curve, and the like. When the target time point is reached, the terminal enters a state of not limiting the electric quantity of the battery to be charged, and the battery to be charged can be normally charged, so that when the charging stop time is reached, the electric quantity of the battery to be charged can reach the full electric quantity, optionally, when the charging stop time point is reached according to the charging stop time point and the current charging state parameters of the battery to be charged, the corresponding target time point of entering the state of not limiting the electric quantity of the battery to be charged when the battery to be charged just reaches the full electric quantity state can be determined, so that when the charging stop time is reached, the electric quantity of the battery to be charged just can reach the full electric quantity, the time of the battery at the high potential is greatly reduced, and the service life of the battery is prolonged.
