s102, if the charging and discharging cycle number of the rechargeable battery is larger than a preset cycle number threshold value and the current state information of the rechargeable battery meets a first preset condition, performing complementary charging on the rechargeable battery so as to charge the voltage of the rechargeable battery to a preset cut-off voltage and charge the current of the rechargeable battery to a preset cut-off current; the preset cut-off voltage is smaller than or equal to the initial cut-off voltage, and the preset cut-off current is smaller than or equal to the initial cut-off current.
In the embodiment of the invention, based on the method that the current state information of the rechargeable battery is judged to meet the first preset condition under the condition that the charging and discharging cycle number is judged to meet the preset cycle number threshold value, and then the rechargeable battery is subjected to supplementary charging, the phenomenon that the mobile terminal is not fully charged due to the polarization of the battery in the later use stage is effectively avoided on the basis of ensuring the charging speed, so that the use experience of a user is improved.
Specifically, as shown in fig. 2, if the number of charge/discharge cycles of the rechargeable battery is greater than the preset number of cycles threshold and the current state information of the rechargeable battery meets the first preset condition in step S102, performing the supplementary charging on the rechargeable battery to charge the voltage of the rechargeable battery to the preset cut-off voltage and charge the current of the rechargeable battery to the preset cut-off current, specifically including:
s1021, judging whether the charging and discharging cycle number of the rechargeable battery of the mobile terminal is larger than a preset cycle number threshold, wherein the preset cycle number threshold is set to be related to the battery capacity in the initial state of the battery, and when the charging is finished and the battery capacity is detected to be a certain preset battery capacity at the moment, setting the currently detected charging and discharging cycle number N as the preset cycle number threshold;
for example: when the initial battery capacity of a certain rechargeable battery is 3300mAh, the preset battery capacity is 80% of the initial battery capacity, namely 2640mAh, and when the charging is finished and the battery capacity is 2640mAh at the moment is detected, taking the detected charging and discharging cycle number 400 as a preset cycle number threshold, in the subsequent charging and discharging process, comparing the detected charging and discharging cycle number with the preset cycle number, and judging whether the charging and discharging cycle number of the rechargeable battery of the mobile terminal is greater than the preset cycle number or not;
if not, executing S1023 to determine that the charging of the rechargeable battery is finished;
if yes, executing S1022, and determining whether current state information of the rechargeable battery meets a first preset condition, where the current state information of the rechargeable battery includes a power consumption current and a current charging voltage; the first preset condition is that the power consumption current of the rechargeable battery is smaller than a preset current threshold, and when the power consumption current is smaller than the preset current threshold, the charging voltage after standing for a preset time is smaller than a preset open-circuit voltage threshold; specifically, if the current state information of the rechargeable battery is judged to meet a first preset condition when the charging and discharging cycle number of the rechargeable battery of the mobile terminal is judged to be larger than a preset cycle number threshold, determining that the rechargeable battery of the mobile terminal is not fully charged;
for example: presetting a current threshold value as 100mA, an open-circuit voltage OCV threshold value as 4.32V and standing for a preset time of 3 min; when the charging and discharging cycle number of the mobile terminal is detected to be 402 and is larger than the preset cycle number 400, comparing the detected power consumption current with a preset current threshold, if the detected power consumption current is 90mA and is smaller than the preset current 100mA, standing the rechargeable battery for 3min, detecting the charging voltage of the rechargeable battery at the moment, and if the detected charging voltage of the rechargeable battery at the moment is 4V and is smaller than a preset open-circuit voltage OCV with the threshold value of 4.32V, determining that the first preset condition is met;
if not, executing S1023, determining that the charging of the rechargeable battery is finished, and finishing the charging operation of the rechargeable battery, specifically, determining that the charging of the rechargeable battery is finished and finishing the charging operation of the rechargeable battery if the current state information of the rechargeable battery is judged not to meet the first preset condition when the charging and discharging cycle number of the rechargeable battery of the mobile terminal is judged to be greater than the preset cycle number threshold; for example: if the power consumption current is detected to be 110mA which is larger than the preset current of 100mA, determining that the mobile terminal does not meet the first preset condition, and finishing charging the rechargeable battery; or when detecting that the power consumption current is 95mA and is smaller than the preset current 100mA, after the rechargeable battery is kept still for 3min, detecting that the charging voltage of the rechargeable battery is 4.6V at the moment and is larger than the preset open-circuit voltage OCV with the threshold value of 4.32V, determining that the mobile terminal does not meet the first preset condition, further determining that the charging of the rechargeable battery is finished, and finishing the charging operation of the rechargeable battery.
If yes, executing S1024, and performing complementary charging on the rechargeable battery to charge the voltage of the rechargeable battery to a preset cut-off voltage and charge the current of the rechargeable battery to a preset cut-off current, wherein the preset cut-off voltage is less than or equal to the initial cut-off voltage, and the preset cut-off current is less than or equal to the initial cut-off current; specifically, when the charging voltage reaches the initial cut-off voltage and the charging current reaches the initial cut-off current, the initial charging is completed, at this time, the initial cut-off current is reduced to 0A, and the initial cut-off voltage is gradually reduced; when the rechargeable battery meets the first preset condition, performing complementary charging on the rechargeable battery so as to charge the voltage of the rechargeable battery to a preset cut-off voltage and charge the current of the rechargeable battery to a preset cut-off current; wherein the preset cut-off voltage can be the known charge cut-off voltage of the batteryThe predetermined cutoff current may be a known charge cutoff current of the batteryWherein,the value range is [4.2V, 4.45V]，The value range is [0.02C, 0.1C]。
Specifically, before the step S1024 of performing the supplementary charging on the rechargeable battery to charge the voltage of the rechargeable battery to the preset cut-off voltage and charge the current of the rechargeable battery to the preset cut-off current, the method further includes:
the method comprises the steps of firstly, judging whether the power consumption current of a rechargeable battery is smaller than a preset current threshold value, specifically, judging whether the power consumption current of the rechargeable battery is smaller than the preset current threshold value in order to ensure that the rechargeable battery is effectively charged in a supplementing manner under the condition that the charging and discharging cycle number of the rechargeable battery meets the preset cycle number threshold value and prevent a larger power consumption condition in the supplementing charging process;
step two, if the judgment result is no, determining that the charging of the rechargeable battery is completed, and ending the charging operation of the rechargeable battery, specifically, for example: the initial capacity of the rechargeable battery is 3300mAh, when the charging is completed, the battery capacity is 2640mAh, it is known that the battery capacity is nearly 660mAh under the polarization of the battery at the later stage of the service life of the battery, if the charging current I at the momentStop blockThe current is 500mA, the preset current threshold value is 100mA, the detected power consumption current is 50mA, the detected power consumption current is smaller than the preset current threshold value and is 100mA, the effective current actually charged into the rechargeable battery is 450mA, the above conditions are met, and according to a formula Q ═ It, wherein Q represents the capacity, and the unit is mAh; i represents the effective current in mA; t represents the time required to be charged and has the unit of h; it was also found that the battery was fully charged in approximately 1.5 hours; if the detected power consumption current is 400mA, which is greater than the preset current threshold value and is 100mA, the effective current actually charged in the rechargeable battery is 100mA, and It can be known that almost 6.6 hours are needed according to the formula Q ═ It, so that when the detected power consumption current is greater than the preset current threshold value, the charging time is prolonged in the process of performing the complementary charging on the detected power consumption current, which affects the user experience.
Step three, if the judgment result is yes, detecting the voltage of the rechargeable battery after the rechargeable battery is kept still for a preset time, specifically, when the power consumption current of the rechargeable battery is judged to be smaller than a preset current threshold, keeping the rechargeable battery still for a period of time, for example: the preset time is 3min, and after 3min, the first detected charging voltage is the detected voltage V of the rechargeable batterybat；
Step four, judging whether the voltage is smaller than a preset open-circuit voltage threshold value or not;
step five, if the judgment result is yes, determining that the current state information of the rechargeable battery meets a first preset condition;
and step six, if the judgment result is negative, determining that the current state information of the rechargeable battery does not meet the first preset condition, and finishing the charging operation of the rechargeable battery.
Specifically, for example: the preset open-circuit voltage OCV is 4.32V, and after the circuit is static for 3min, the charging voltage V detected for the first timebatIf the current state information of the rechargeable battery is 4V, determining that the current state information of the rechargeable battery meets a first preset condition; if the battery is kept still for 3min, the charging voltage detected for the first time is VbatAnd if the current state information of the rechargeable battery is 5V, determining that the current state information of the rechargeable battery does not meet the first preset condition, further determining that the rechargeable battery is charged, and finishing the charging operation of the rechargeable battery.
When the above S1022 determines whether the current state information of the rechargeable battery meets the first preset condition, it is determined whether the power consumption current of the rechargeable battery is smaller than the preset current threshold, and after the rechargeable battery is left standing for the preset time, the order of detecting whether the voltage of the rechargeable battery is smaller than the preset open-circuit voltage threshold is not required, or after the rechargeable battery is left standing for the preset time, it is determined whether the voltage of the rechargeable battery is smaller than the preset open-circuit voltage threshold, and then, it is determined whether the power consumption current of the rechargeable battery is smaller than the preset current threshold;
wherein, in the initial stage of the battery, the battery is a fresh battery, and the polarization is small, so thatBefore charging the voltage of the rechargeable battery of the mobile terminal to the initial cut-off voltage and charging the current of the rechargeable battery to the initial cut-off current in S101, the method further includes:
according to a first calculation formula VStop 0＝VAnti-nor+ Δ V, determining an initial cut-off voltage of a rechargeable battery of the mobile terminal; and the number of the first and second groups,
according to a second calculation formula IStop 0＝kIAnti-norDetermining the initial cut-off current of the rechargeable battery;
wherein, VStop 0Represents the initial cut-off voltage, the delta V represents the voltage compensation value, the delta V is more than or equal to 0, and the value range of the delta V can be [0V, 0.1V ]]；VAnti-norRepresents a preset cut-off voltage of a value of 4.2V, 4.45V]；IStop 0Denotes initial cut-off current, k is constant, k ≧ 1, IAnti-norThe preset cut-off current is represented, and the value range is [0.02C, 0.1C ]]。
Specifically, before determining whether the number of charge/discharge cycles of the rechargeable battery of the mobile terminal is greater than the preset cycle threshold in the above S1021, the method further includes:
determining a battery threshold parameter of the mobile terminal according to the electrochemical characteristics of the battery of the mobile terminal, wherein the battery threshold parameter comprises: at least one of a preset cycle threshold, a preset cut-off voltage, a preset cut-off current, a preset current threshold and a preset open-circuit voltage threshold;
and storing the determined battery threshold parameter into a storage module.
Wherein, in order to avoid appearing overcharging to the in-process that charges rechargeable battery, and cause the damage to the battery, it is less than predetermined cutoff voltage, specific to need to satisfy predetermined open circuit voltage threshold value, for example: the preset open-circuit voltage threshold OCV is 4.32V, and the preset cut-off voltage VAnti-nor4.45V, standing for 3min, and detecting the charging voltage VbatThe voltage is 4V, because the detected charging voltage is smaller than the preset open-circuit voltage threshold value and the preset open-circuit voltage threshold value is smaller than the preset cut-off voltage, under the condition that the power consumption current also meets the preset power consumption current, the complementary charging can be carried out; if the predetermined open-circuit voltage threshold OCV is 5V, the predetermined cut-off voltage VAnti-norAt 4.45V, quietAfter 3min, the detected charging voltage Vbat4.8V, the detected charging voltage is less than the preset open circuit voltage threshold, however, the OCV is greater than the preset cut-off voltage V due to the preset open circuit voltage threshold of 5VAnti-nor4.45V, which causes overcharge and thus damage to the rechargeable battery, and therefore, when the preset open circuit voltage threshold is greater than the preset cutoff voltage, the supplementary charging is not performed.
Specifically, an embodiment of the present invention provides a method for charging a terminal battery, where the method includes: a charging method 1 and a charging method 2, wherein in this embodiment, the charging method of the terminal battery specifically includes:
(1) determining a battery threshold parameter of the mobile terminal according to the electrochemical characteristics of the battery of the mobile terminal, and storing the determined battery threshold parameter into a storage module, wherein the battery threshold parameter comprises: at least one of a preset initial cut-off voltage, a preset initial cut-off current, a preset standing time threshold, a preset cycle threshold, a preset cut-off voltage, a preset cut-off current, a preset current threshold and a preset open-circuit voltage threshold;
(2) charging the voltage of the rechargeable battery to an initial cut-off voltage and charging the current of the rechargeable battery to an initial cut-off current by adopting a charging mode 1;
(3) judging whether the charging and discharging cycle number of a rechargeable battery of the mobile terminal is larger than a preset cycle number threshold value or not;
(4) if the judgment result is negative, the charging is determined to be finished;
(5) if the judgment result is yes, judging whether the current state information of the rechargeable battery meets a first preset condition, wherein the first preset condition is as follows: judging whether the power consumption current of the rechargeable battery is smaller than a preset current threshold value or not; if yes, detecting the voltage of the rechargeable battery after the rechargeable battery is kept still for a preset time; judging whether the voltage is smaller than a preset open-circuit voltage threshold value or not; if so, determining that the current state information of the rechargeable battery meets a first preset condition;
(6) if the judgment result is yes, charging the voltage of the rechargeable battery to a preset cut-off voltage and charging the current of the rechargeable battery to a preset cut-off current by adopting a charging mode 2;
(7) if the judgment result is no, the charging operation is finished for the rechargeable battery.
Specifically, based on the system flow diagram of the charging method for the terminal battery, a specific implementation of charging in the mobile terminal is provided; the mobile terminal adopts a half-voltage + PMIC charging mode, and the charging mode of the mobile terminal can be low-voltage charging, high-voltage charging and the like, and is not limited to half-voltage + PMIC charging;
under the condition of 25 ℃, charging the mobile terminal with the same initial state by adopting a 10V/2.25A adapter, wherein the mobile terminal can be in a screen-off state or a screen-on state in a use state and the like in the charging process; the mobile terminal has a battery capacity of 3330mAh and a conventionally known cut-off voltage At 4.38V, the conventional well-known cutoff currentIt was 0.05C. According to the charging method of the terminal battery and the basic electrochemical properties of the terminal battery, the charging method specifically comprises the following steps:
step one, determining a battery threshold parameter of the mobile terminal according to the electrochemical characteristics of the battery of the mobile terminal, and storing the determined battery threshold parameter into a storage module; for example: the battery threshold parameters include: initial charge cut-off voltageAt 4.45V, initial charge cutoff currentIs 600 mA; the preset cycle number threshold N is 400; the preset standing time threshold value is 3min, the preset current threshold value is 100mA, the preset open-circuit voltage threshold value OCV is 4.32V, and the preset cut-off current is0.05C, preset cut-off voltage 4.38V;
step two, charging the voltage of the rechargeable battery to 4.45V of the initial charging cut-off voltage and charging the current of the rechargeable battery to 600mA of the initial charging cut-off current by adopting a charging mode 1;
specifically, in the initial stage of the battery, the battery is a fresh battery, the polarization is small, the voltage of the rechargeable battery is charged to the initial cut-off voltage and the current of the rechargeable battery is charged to the initial cut-off current, the charging speed can be greatly increased while the full charge rate is ensured, for example, after the half-voltage 10V/2.25A charging IC of the mobile terminal detects the initial cut-off voltage, the charging current is reduced by 500mA, and then the charging current is recharged to the initial cut-off voltage, so that the steps are repeated cyclically until the charging current is reduced to 1A, then 1A is charged to the initial cut-off voltage, and the PMIC of 5V/2A is charged until the initial cut-off voltage is 4.45V and the initial cut-off current is 600 mA;
in the using process of the mobile terminal, the battery impedance is increased more along with the aging of the battery, and if the initial cut-off voltage and the initial cut-off current are used as cut-off conditions for completing the charging, the charging capacity is reduced by 5% or more, so after the voltage of the rechargeable battery is charged to the initial cut-off voltage and the current of the rechargeable battery is charged to the initial cut-off current by the charging method 1, the method further includes:
step three, judging whether the charging and discharging cycle number of the rechargeable battery of the mobile terminal is larger than a preset cycle number threshold 400 or not by acquiring the charging and discharging cycle number of the rechargeable battery calculated by the fuel gauge Ic;
step four, if the judgment result is negative, the charging is determined to be finished;
step five, if the judgment result is yes, comparing the detected power consumption current with a preset current threshold, for example, the detected power consumption current is 50mA and is smaller than the preset current threshold 100mA, standing the rechargeable battery for 3min, and entering a supplementary charging logic if the voltage of the rechargeable battery is detected to be 4V and is smaller than the preset open-circuit voltage threshold 4.32V, and starting the PMIC to execute step six;
step six, charging the voltage of the rechargeable battery to a preset cut-off voltage of 4.38V and charging the current of the rechargeable battery to a preset cut-off current of 0.05C by adopting a charging mode 2, and ending the charging;
and step seven, if the judgment result is negative, finishing the charging operation of the rechargeable battery.
By adopting the charging method in the embodiment of the application, on the premise of not losing each performance parameter of the battery, the complementary charging is carried out to ensure the full charging rate in the whole life cycle of the rechargeable battery, table one is the charging condition in the life cycle of the battery, and the table one shows that:
