In order to explain the technical solution described in the present application, the following description will be given by way of specific examples.
The embodiment of the application aims at the condition that the charging time length is shorter, a primary protection mode can be started after the charging is fully charged for the first time, and the charging enabling is started and closed at the moment, so that the electric quantity of the battery is circularly recharged (for example, the electric quantity is circulated between 100% and 90%) between full charge and a higher electric quantity (first electric quantity) lower than the full charge. And recording the number of recharging cycles or the starting time of the primary protection mode. Each recharging cycle may have a range of durations, such as 30-60 minutes, that are related to the power consumption of the device.
And aiming at the condition that the charging time length far exceeds the standard charging time length, after the number of cyclic recharging times reaches the preset number of cyclic times N (or the starting time of the primary protection mode reaches a certain time) in the primary protection mode, judging that the charging is carried out for a very long time and a secondary protection mode is started. After the secondary protection mode is started, the charging enable switch is controlled, and the electric quantity can be subjected to recharging circulation in two ranges of lower electric quantity. The setting of the upper and lower limit values of the electric quantity in the secondary protection mode depends on the safe electric quantity range of the battery, and can be set according to the battery parameters. The upper and lower limit electric quantity values of the secondary protection mode are generally smaller than the lowest value (first electric quantity) of the primary protection recharging quantity. Such as between 60% and 80%. After entering the secondary protection mode, the system can also send a warning prompt of long-time charging to the user through the UI.
Fig. 1 is a schematic flow chart of an implementation process of a battery charging protection method provided in an embodiment of the present application, and as shown in the figure, the method may include the following steps:
step S101, when the battery is charged, the battery stops being charged after being fully charged for the first time in the charging process, and the battery is repeatedly charged in a primary protection mode, wherein the electric quantity of the battery in the primary protection mode is larger than or equal to the first electric quantity.
In the embodiment of the present application, if the mobile terminal without the charging path management is directly plugged in the charger, the system will always consume the electric quantity of the battery, and continue to charge the battery after the electric quantity of the battery is consumed by a part, so that the battery will always be in a high-potential charging and discharging cycle, and actually, the number of times of charging and discharging the battery at the high potential is limited, for example, a battery cell is repeatedly charged between 4.1V and 4.2V, and has a life value, for example, the life value of battery recharging between 4.1V and 4.2V is 6000 times. Without limiting this number, cycling the battery at such a high potential often quickly depletes the battery of its life and performance. Therefore, it is necessary to control the number of times the battery is recharged between 4.1V and 4.2V. If a user is used to insert a charger for charging for a long time, the voltage corresponding to the lower limit value electric quantity which can be set is lower, for example, 4.0V, the electric quantity during recharging is cyclically recharged between 4.0V and 4.2V, which is equivalent to prolonging the recharging time for one time, and assuming the same charging time, the number of recharging times is reduced, and the number of recharging times of the battery is also prolonged, which is equivalent to prolonging the service life of the battery. The electric quantity value of the battery corresponding to the lower voltage limit during recharging can be called as a first electric quantity, so that the battery can be controlled to be cyclically recharged between the first electric quantity and the full electric quantity.
It should be noted that 4.0V, 4.1V, 4.2V and 6000 times in the above examples are merely examples of one type of battery, and are not meant to represent the case of all types of batteries in practical use.
Step S102, after a trigger event for switching a protection mode is detected, repeatedly charging a battery in a secondary protection mode, wherein the electric quantity of the battery in the secondary protection mode is less than or equal to a second electric quantity, and the second electric quantity is less than the first electric quantity.
In the embodiment of the application, even if the service life of the battery can be prolonged to a certain extent by reducing the first electric quantity, the high-potential recharging not only influences the service life and the performance of the battery, but also brings risks to the use safety of the battery. Therefore, the embodiment of the application also sets a secondary protection mode. A trigger event may be set and when the trigger event is detected, a switch is made to the secondary protection mode in which the battery is recharged. The selection of the critical value of the electric quantity in the secondary protection mode is also determined according to the life value of the battery cell in which range of recharging cycle times, and generally the cycle life value of the low-voltage interval is much larger than that of the high-voltage interval, for example, if the life value of the battery cell used in the cycling recharging between 3.7V and 3.9V is 20000 times, the electric quantity values corresponding to the two voltage parameters can be found by referring to the two voltage parameters, so as to set the second electric quantity and the third electric quantity. The service life of the battery is greatly prolonged by low potential recharging, and the safety of the battery is higher.
As another embodiment of the present application, the trigger event for switching the protection mode includes:
in the primary protection mode, the time for recharging the battery is greater than a first time threshold.
In the embodiment of the application, the recharging time of the battery in the primary protection mode is controlled by setting the first time threshold, so that the number of times of the battery in high-potential cycle recharging is controlled, and the service life of the battery is prolonged. The first time threshold may be set according to a specific setting, for example, assuming that the number of times of recharging the battery in the high potential cycle is 6000, the time t of recharging the battery in the high potential cycle may be determined according to the mobile terminal and the performance of the battery, assuming that the user charges the battery once a day, and the expected life of the battery or the mobile terminal for updating is 2 years, the maximum time allowed for charging the high potential per day may be obtained by t/(365 × 2), and the first time threshold may be set to the maximum time, or may be set to the maximum time which is shorter than the maximum time.
As another embodiment of the present application, after detecting a trigger event for switching the protection mode, the method further includes:
and sending out prompt information of overlong charging time.
In the embodiment of the application, after the trigger event for switching the protection mode is reached, the user can be prompted to pull out the charger through the prompt information, and the sound prompt mode and the vibration prompt mode can be used.
According to the embodiment of the application, the battery is repeatedly charged by setting a two-stage protection mode, the electric quantity of the battery is kept above a first relatively high electric quantity in the one-stage protection mode, and after a switching condition is met, the electric quantity of the battery is controlled below a second relatively low electric quantity in the two-stage protection mode; in this way, in the mobile terminal without the charging path management, even though the mobile terminal is charged by a charger, the battery is switched from a high-potential charging and discharging cycle to a low-potential charging and discharging cycle after the switching condition is reached, so that the cycle number of high-potential charging and discharging of the battery is reduced, and the service life of the battery is prolonged.
Fig. 2 is a schematic flow chart of an implementation of a battery charging protection method according to another embodiment of the present application, as shown in the figure, the method may include the following steps:
step S201, when the battery is charged, after the battery is fully charged for the first time in the charging process, the battery is stopped to be charged, and a primary protection mode is started.
Step S202, in the primary protection mode, after the electric quantity of the battery is reduced to the first electric quantity, the battery is charged repeatedly.
Step S203, in the primary protection mode, after the battery is fully charged, stopping charging the battery.
Step S202 and step S203 are executed cyclically.
In the embodiment of the present invention, in the process of executing steps S202 and S203 in a loop, after the number of times of repeatedly charging the battery is greater than the second threshold value, the battery is charged in a trickle charge manner. The second time threshold is smaller than the first time threshold during switching. Of course, if the switching condition is the time threshold, the charging mode for charging the battery is trickle charging after the time for repeatedly charging the battery is greater than the second time threshold. The second time threshold is less than the first time threshold at handover. The second time threshold is less than the first time threshold at handover.
And step S204, under the primary protection mode, when the number of times of repeatedly charging the battery is greater than a first time threshold value, switching to a secondary protection mode.
In the embodiment of the present application, the first count threshold may be set in the following manner:
by the formula
Determining the maximum value of the first time threshold value, and determining the first time threshold value according to the maximum value of the first time threshold value;
wherein N ismaxRepresents the maximum value of the first threshold, n1Representing the number of times the battery has been recharged between the first charge and full charge, t1Represents the predicted service life of the battery, f1Representing the charging frequency of the battery.
Assuming that the number of times of the electric battery when being repeatedly charged between the first electric quantity and the full electric quantity is 6000, the expected service life of the battery (or the time for updating the battery or the mobile terminal where the battery is located) is two years, and the charging frequency of the battery is once per night, the maximum value of the first time threshold value can be calculated by a formula as follows: 6000/(365 × 2) ═ 8.2, 8 times after 8.2 rounding. The first count threshold may be set to a value of 8 or less than 8.
Step S205, in the secondary protection mode, after the electric quantity of the battery decreases to the third electric quantity, the battery is charged repeatedly.
In this embodiment of the application, the switching process of switching the first protection mode to the second protection mode may be: when the number of times of repeatedly charging the battery is greater than the first time threshold value, after the battery is fully charged to the full capacity in the cycle (the first time threshold value +1 time), the battery is switched to the secondary protection mode, so that the battery is directly decreased from the full capacity to the third battery in the secondary protection mode, and a cycle process is performed; or, when the number of times of repeatedly charging the battery is greater than the first time threshold, after the electric quantity is fully charged to the full electric quantity in this cycle (the first time threshold +1 times), the electric quantity of the battery is switched to the secondary protection mode only after the electric quantity of the battery is reduced from the full electric quantity to the second electric quantity, which is not limited herein.
Step S206, in the secondary protection mode, after the electric quantity of the battery increases to the second electric quantity, stopping charging the battery.
Step S205 and step S206 are executed in a loop. And the charging mode for charging the battery in the secondary protection mode is constant current charging.
According to the number of times life when the battery is in recharging between first electric quantity and full electric quantity, estimated service life and charging frequency, the maximum number of times that the circulation is recharged under first protection mode can be calculated to rationally set up the number of times that recharges of battery under the one-level protection mode, prolong the life-span of battery.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
