In the above method, the first time is adjusted to the second time, so that the electronic device can determine that the charging chip is stopped to be charged once in the subsequent steps, and it can be understood that the fact that the charging chip is stopped to be charged once indicates that the first battery is fully charged.
And the charging path of the first battery can be disconnected, so that the first battery is prevented from being charged again when the subsequent charging chip is charged again; in the second charging stage, since the charging path of the first battery is in a disconnected state, the charging chip does not charge the first battery any more, and only charges the second battery, so that the second battery can be fully charged in the second charging stage.
When the electronic equipment is in the off-screen state, the charging channel of the first battery is disconnected, so that the situation that the electronic equipment is large in power consumption and unstable in operation due to the fact that related operations such as disconnection of the charging channel of the first battery are executed when the electronic equipment is in the on-screen state can be avoided.

In addition, when the electronic equipment is disconnected from the charger, the charging passage of the first battery may be in a disconnected state, so that when the electronic equipment is disconnected from the charger, the electronic equipment can also control the charging passage of the first battery to be connected, and the charging passage of the first battery can be in a communicated state when the electronic equipment is connected with the charger next time, thereby ensuring that the next charging chip can normally charge the first battery.
It should be appreciated that disconnecting the electronic device from the charger may occur at any time. For example, when the charging path of the first battery is in a disconnected state and the charging chip charges the second battery, if the step of controlling the charging path of the first battery to be connected is not performed, the charging path of the first battery is in a disconnected state when the electronic device is connected with the charger next time, and the charging chip cannot charge the first battery.

In the charging process of the electronic equipment, the MOS is equivalent to a control switch, and has two working states, namely disconnection and connection. If the MOS is disconnected, a charging passage between the charging chip and the first battery is disconnected, the current of the charging chip cannot flow to the first battery, and the charging chip cannot charge the first battery; if the MOS is connected, a charging channel between the charging chip and the first battery is connected, the current of the charging chip can flow to the first battery, and the charging chip can charge the first battery.

"and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a alone, a and B together, and B alone, wherein a, B may be singular or plural. The character "/" generally indicates that the context-dependent object is an "or" relationship. "at least one of" or the like means any combination of these items, including any combination of single item(s) or plural items(s). For example, at least one (one) of a, b, or c alone may represent: a alone, b alone, c alone, a combination of a and b, a combination of a and c, b and c, or a combination of a, b and c, wherein a, b, c may be single or plural. Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
The electric quantity of the electronic equipment is equal to the life line of the electronic equipment, as the functions of the electronic equipment are increased, the screen is increased, the endurance time of the electronic equipment is shortened, and the charging problem of the electronic equipment is a problem of important attention of users, in particular to the electronic equipment such as a folding screen mobile phone.
The folding screen electronic device of the inward folding type shown in fig. 1 and the folding screen electronic device of the outward folding type shown in fig. 2 are large in screen, consume a large amount of electricity and have short endurance.
Currently, in order to improve the endurance time of an electronic device, two batteries may be disposed in the electronic device, and the two batteries may be charged respectively through two charging chips, or may be charged simultaneously to the two batteries through one charging chip.
However, when two batteries are charged simultaneously by one charging chip, the charge speed and the final full charge capacity of the two batteries are affected by the capacity of the two batteries, the impedance of the charging path, and the like, and it is difficult to fully charge both batteries in one charge, resulting in capacity loss.
Specifically, as shown in fig. 3, one charging chip is connected to the battery 1 and the battery 2, and the one charging chip simultaneously charges the battery 1 and the battery 2 (the battery 1 may be a small battery, and the battery 2 may be a large battery). The battery 1 has small capacity, the charging link from the charging chip to the battery 1 is short, the path impedance is small, the charging current value of the battery 1 is larger than that of the battery 2 during charging, and the charging voltage of the battery 1 increases rapidly. The judging condition of the cut-off charging of the charging chip is that the charging voltage value of the battery is larger than or equal to a set threshold A, meanwhile, the charging current output by the charging chip is smaller than or equal to a set threshold B, and the charging current of the battery 1 is large and small in capacity, so that the charging voltage value of the battery 1 reaches the threshold A first, when the current output by the charging chip is smaller than B, the charging is stopped, at the moment, the charging voltage value of the battery 2 is smaller, the threshold A is not reached, and when the charging is stopped, the electric quantity of the battery 2 is not full, and capacity loss is caused.
In view of the above, the present application may provide a battery charging control method, an electronic device, a chip system, a computer readable storage medium, and a computer program product, in which, since the charge amount of the battery 1 is full and the charge amount of the battery 2 is not full when the charging chip is charged for the first time, the charging path between the charging chip and the battery 1 may be disconnected after the charging chip is charged for the first time, and the state of the charging chip may be reset to be the charging state, so that the charging chip charges the battery 2 again until the charging chip is charged for the second time, at which time the charge amount of the battery 2 is full, and the charging path between the charging chip and the battery 1 may be connected; in this way, in one-time charging, the electric quantity of the battery 1 and the electric quantity of the battery 2 are guaranteed to be full, and the use experience of a user is guaranteed.

S11, the charging management module receives information of the connection charger.
It should be appreciated that when the electronic device is connected to the charger, the charge management module in the electronic device may receive information to connect to the charger.
The electronic device may be connected to the charger in a plurality of ways, that is, may receive information of the connection to the charger in a plurality of ways.
In some embodiments, the charger is a wired charger, and the charge management module may receive information to connect the charger when the charger is plugged into the charging interface of the electronic device through the charging interface of the charger.
In other embodiments, the charger is a wireless charger, the wireless charger includes a charging coil, the charging is performed by using an electromagnetic induction principle, and when the electronic device is placed at the charging coil of the wireless charger, the charging management module may receive information of connecting the charger.
S12, the charging management module charges the charging chip and writes the cut-off voltage value, the cut-off current value and the charging current value into the charging chip.
The charging chip in the electronic device may be a BUCK chip. The application does not limit the type of the charging chip.
When the charging management module receives the information of the connection charger, the charging management module can enable the charging chip to charge a battery connected with the charging chip in the electronic equipment.
Wherein the cut-off current value and the cut-off voltage value are preset; the off-current value is a charging current value when the charging chip is fully charged to the battery 1 and/or the battery 2, and the off-voltage value is a charging voltage value when the charging chip is fully charged to the battery 1 and/or the battery 2.
For example, the off-current value may be 200mA and the off-voltage value may be 4.8V.
The cut-off current value and the cut-off voltage value are used for determining the charging condition of the battery, and when the charging voltage value of the charging chip reaches the cut-off voltage value (the charging voltage value is greater than or equal to the cut-off voltage value) and the charging current value reaches the cut-off current value (the charging current value is less than or equal to the cut-off current value), the charging chip can determine that the battery is fully charged.
Thus, when the charging chip determines that the battery in the electronic device is charged, the charging of the battery connected with the charging chip in the electronic device can be stopped, and the charging state of the battery can be updated to be charged.
Based on this, the charging chip can determine whether or not the charging needs to be stopped by the cutoff voltage value and the cutoff current value.
The charging current value is an output current value of the charging chip, namely, a current value for charging a battery in the electronic equipment when the charging chip starts charging.
Based on this, the charge management module writes the charge current value to the charge chip, and the charge chip can be facilitated to charge the battery 1 and the battery 2 in the electronic device based on the charge current value.
And S13, the charging chip charges the battery 1 and the battery 2.
The charging chip may charge the battery 1 and the battery 2 in the electronic device based on the charging current value written to the charging chip by the charging management module.
It will be appreciated that when the charging chip charges the battery 1 and the battery 2, a current is present in the charging path between the charging chip and the battery 1, and a current is also present in the charging path between the charging chip and the battery 2.
And S14, when the charging voltage value of the charging chip reaches the cut-off voltage value and the charging current value reaches the cut-off current value, the charging of the battery 1 and the battery 2 is stopped, and the charging state is updated to be the charging completion.
Wherein the charging state includes two states of being charged and being charged.
In some embodiments, upon determining that charging of the battery in the electronic device is complete, the charging chip may write an identification to a status register of the charging chip that identifies the completion of charging.
For example, the charging chip writes an identifier "0" into a status register of the charging chip, and the identifier "0" indicates that the charging status is charging completion.
Based on the above description, when the charge voltage value of the charge chip to charge the battery 1 and the battery 2 reaches the cutoff voltage value and the charge current value reaches the cutoff current value, it may be determined that the cutoff condition is satisfied, and thus, the charge chip may stop charging the battery 1 and the battery 2.
It will be appreciated that when the charging of the battery 1 and the battery 2 is stopped by the charging chip, no current is present in the charging path between the charging chip and the battery 1, and no current is present in the charging path between the charging chip and the battery 2.
It should be understood that the electronic device includes two batteries, namely, battery 1 and battery 2, and then the charging chip needs to charge both battery 1 and battery 2; referring to fig. 3, the battery 2 is connected between the charging chip and the battery 1, the charging link from the charging chip to the battery 1 is short, and the path impedance is small, so that the charging current value of the battery 1 is larger than the battery 2, the voltage of the battery 1 increases faster, the charging current value of the battery 1 is large, the charging voltage value of the battery 1 reaches the off-voltage value faster (the charging voltage value of the charging chip is larger than or equal to the off-voltage value), and the charging current value of the charging chip reaches the off-current value faster (the charging current value of the charging chip is smaller than or equal to the off-current value).
Then, when the charging chip detects that the charging voltage value reaches the cut-off voltage value for the first time and the charging current value reaches the cut-off current value, the charging of the battery 1 and the battery 2 is stopped, and the charging state is updated to be the charging completion, at this time, the battery 1 is actually fully charged, and the battery 2 may not be fully charged.
S15, the charging management module reads the charging state from the charging chip.
The charging management module may periodically read the charging state from the charging chip after receiving the information of the charger.
For example, the charge management module may read the state of charge from the charging chip every 1 s.
Based on this, the charge management module reads the state of charge from the charge chip, and can prepare data for the charge management module to perform the next operation according to the state of charge.
S16, the charging management module receives the charging state.
Based on S15, the charge management module may receive the charge state read from the charge chip.
S17, the charging management module judges whether the charging state is charging completion or not, and whether the charge interception times are 0 or not.
The charge stop times are times when the charging chip stops charging the battery connected with the charging chip.
Since the charging state includes both the charging-in state and the charging-out state, if the charging chip is charging the battery 1 and/or the battery 2, the charging state is charging at this time; if the charging chip stops charging the battery 1 and the battery 2, the charging state is completed at this time.
When the charging state is charging completion and the charge cutoff times are 0, the charging management module determines that the charging chip detects that the primary charging voltage value reaches the cut-off voltage value and the charging current value reaches the cut-off current value, and stops charging once, and the updated charging state is charging completion once.
When the charging state is not charging completion and the cut-off number is 0, the charging management module determines that the charging chip is charging the battery 1 and/or the battery 2.
When the charging state is charging completion and the charge cutoff frequency is 0, the charging management module may execute S18; when the state of charge is not charging completion, the charge management module waits for the next execution S15 and S16.
S18, the charging management module updates the charge interception times to 1.
Since the charging state is charging completion and the charge cutoff frequency is 0, it means that the charging chip has detected that the charging voltage value reaches the cutoff voltage value once and the charging current value reaches the cutoff current value, and stops charging once, and the updated charging state is charging completion once, that is, the charge cutoff frequency is cutoff once, so that the charge cutoff frequency can be updated to 1.
And S19, the charging management module judges whether the electronic equipment is in a screen-off state.
Wherein S19 is an optional step.
The charging management module can judge whether the electronic equipment is in a screen-off state or not in various modes.
In some embodiments, the charging management module may determine whether the electronic device is in an off-screen state by receiving an on-screen event sent by the power management service module.
If the charging management module receives the information of the connection charger and then receives the screen-off event, or the electronic equipment is in the screen-off state when receiving the information of the connection charger, and the charging management module does not receive the screen-on event, the charging function module can determine that the electronic equipment is in the screen-off state; when the information of the connection charger is received, the electronic equipment is in a bright screen state, and after the information of the connection charger is received, the charging management module does not receive a screen-off event, and then the charging functional module can determine that the electronic equipment is not in the screen-off state.
In some embodiments, the electronic device may register a monitor screen-off event during a startup or a restart process, and when monitoring that the display screen of the electronic device is off, the power management service module may send the screen-off event to the charging management module to notify the charging management module that the electronic device is off.
In other embodiments, an off-screen application is included in the electronic device, and the off-screen application is capable of sending an off-screen event to the charge management module to notify the charge management module that the electronic device has been off-screen when the electronic device is off-screen.
It should be understood that, when the user uses the electronic device, the electronic device is usually in a bright screen state, if the electronic device is in a bright screen state, the operation of turning off the MOS is performed, and the battery 2 is continuously charged, at this time, only one battery of the electronic device is charged, and when the user uses the electronic device to cause the power consumption of the electronic device to be large, the electronic device is easy to generate a heat phenomenon.
Therefore, the charging management module can judge whether the electronic equipment is in the off-screen state, so that when the electronic equipment is in the off-screen state, the operation of switching off the MOS after the execution can be conveniently performed, and the situation that when the electronic equipment is in the on-screen state, the MOS is switched off and the battery 2 is continuously charged can be avoided, so that the power consumption of the electronic equipment is larger.
When the electronic device is in the off-screen state, the charging management module may execute S20; when the electronic device is not in the off-screen state, the charge management module may perform S21.
S20, the charge management module turns off the MOS to turn off the charge path of the battery 1.
Among them, metal-oxide-semiconductor (MOS) field effect transistors, abbreviated as metal-oxide-semiconductor field effect transistors.
Referring to fig. 3, in the electronic device, a MOS is provided in a charging path through which a charging chip is connected to a battery 1.
In the starting-up process of the electronic equipment, the MOS is equivalent to a slide rheostat, and the charging voltage values of the battery 1 and the battery 2 can be controlled by adjusting the MOS, so that the charging voltages of the battery 1 and the battery 2 are kept balanced.
In the charging process of the electronic equipment, the MOS is equivalent to a control switch, and has two working states, namely disconnection and connection. If the MOS is disconnected, a charging path between the charging chip and the battery 1 is disconnected, the current of the charging chip cannot flow to the battery 1, and the charging chip cannot charge the battery 1; if the MOS is connected, a charging path between the charging chip and the battery 1 is connected, and a current of the charging chip can flow to the battery 1, and the charging chip can charge the battery 1.
In short, the charging management module may disable the charging chip from charging the battery 1 by turning off the MOS; the battery 1 can be charged by connecting the MOS so that the charging chip can charge the battery.
It will be appreciated that when the charge management module turns off the MOS, even if the charge management module controls the charging chip to start charging, no current is present in the charging path between the charging chip and the battery 1.
In some embodiments, after updating the number of times of charge interception to 1, the charge management module directly turns off the MOS without determining whether the electronic device is in the off-screen state, so that the charging path of the battery 1 is turned off.
In other embodiments, after updating the number of times of charge interception to 1, if it is determined that the electronic device is in the off-screen state, the charge management module turns off the MOS, so that the charging path of the battery 1 is turned off.
Based on the above, when the electronic equipment is in the off-screen state, the charge management module executes the operation of disconnecting the MOS, so that the charging path of the battery 1 is disconnected, the use of the electronic equipment by a user can be not influenced, and the use experience of the user is ensured.
S21, judging the charging state and the cut-off times.
Based on the above description, when the electronic device is not in the off-screen state, that is, in the on-screen state, the charging management module turns off the MOS to continue charging the battery 2, and the power consumption of the electronic device is large.
Therefore, when the electronic equipment is not in the screen-off state, the charging management module can end judging the charging state and the number of times of intercepting charging, and start normal charging, so that the situation that when the electronic equipment is in the screen-on state, the MOS is disconnected and the battery 2 is continuously charged, and the power consumption of the electronic equipment is larger can be avoided.
S22, the charging management module charges the charging chip.
It should be understood that when the MOS is turned off, the current of the charging chip cannot flow to the battery 1, and the charging chip cannot charge the battery 1, so that at this time, the charging management module controls the charging chip to start charging, and the charging chip can only charge the battery 2.
In some embodiments, after the MOS is turned off, the charge management module may detect whether the battery 2 is fully charged, and if not, recharge the charging chip, i.e. set the state of the recharging chip to the charging state.
In other embodiments, after the MOS is turned off by the charging management module, the charging chip may be directly recharged, i.e. the state of the recharging chip is set to be the charging state.
The implementation of charging the battery by the charging chip in S22 is similar to that in S12 in the embodiment shown in fig. 6, and will not be described here again.
And S23, the charging chip continuously charges the battery 2.
As is clear from S22, when the charging chip is charged after the MOS is turned off, the charging chip charges the battery 2 and does not charge the battery 1.
The implementation of S23 to charge the battery 2 by the charging chip is similar to S13 in the embodiment shown in fig. 6, and will not be described here again.
And S24, when the charging voltage value of the charging chip reaches the cut-off voltage value and the charging current value reaches the cut-off current value, the charging chip stops charging the battery 2, and the charging state is updated to be the charging completion.
Since the MOS is turned off, the charging chip charges the battery 2 and does not charge the battery 1, and at this time, when the charging core determines that the charging voltage value charged to the battery 1 and the battery 2 reaches the cutoff voltage value and the charging current value reaches the cutoff current value, it may be determined that the battery 2 is fully charged, and at this time, both the battery 1 and the battery 2 are fully charged, so that the charging chip may stop charging the battery 2.
S25, the charging management module reads the charging state from the charging chip.
The charge management module may periodically read the state of charge from the charging chip.
The implementation of S25 is similar to that of S15 in the embodiment shown in fig. 6, and will not be described herein.
S26, the charging management module receives the charging state.
Based on S25, the charge management module may receive the charge state read from the charge chip.
S27, the charging management module judges whether the charging state is charging completion and whether the charge interception times are 1.
Since the charging state includes both the charging-in state and the charging-out state, if the charging chip is charging the battery 1 and/or the battery 2, the charging state is charging at this time; if the charging chip stops charging the battery 1 and the battery 2, the charging state is completed at this time.
When the charging state is charging completion and the charge cutoff times are 1, the charging management module determines that the charging chip has detected that the charging voltage value reaches the cut-off voltage value twice and the charging current value reaches the cut-off current value, and stops charging twice, and the updated charging state is charging completion twice.
When the state of charge is not charging completion, it indicates that the charging chip is charging the battery 1 and/or the battery 2.
When the charging state is charging completion and the charge cut-off frequency is 1, the charging management module executes S28; when the state of charge is not charging completion, the charge management module waits for the next execution S25 and S26.
S28, the charging management module updates the charge interception times to 2.
When the charging state is charging completion and the charge cutoff frequency is 1, the charging management module determines that the charging voltage value of the battery 1 and the battery 2, which are charged twice, has been detected by the charging chip to reach the cutoff voltage value, and the charging current value has reached the cutoff current value, and stops charging twice, and the updated charging state is charging completion twice, that is, the charge cutoff frequency is updated to 2.
Optionally, after S28, it may further include:
the charging management module judges whether the electronic equipment is in a screen-off state; while in the off-screen state, the charge management module may perform S29 of connecting the MOS to connect the charge path of the battery 1; when the charging management module is not in the screen-off state, the charging management module can end judging the charging state and the charge interception times.
S29, the charge management module connects the MOS devices so as to connect the charge paths of the battery 1.
Based on the description of S24-S28, at this time, the electronic device has stopped charging for the second time, the electric quantity of the battery 1 has been full when the charging is stopped for the first time, and the electric quantity of the battery 2 has been full when the charging is stopped for the second time, so that after the electric quantity of the battery 2 is full, the charging management module may connect the MOS, so that the charging path between the charging management module and the battery 1 is connected, thereby ensuring that the subsequent charging chip can normally charge the battery 1.
It can be understood that when the charge management module is connected to the MOS, if the charging chip charges the battery 1, a current exists in a charging path between the charging chip and the battery 1.
Based on the above description, the charge management module may periodically read the state of charge, and correspondingly, the charge management module may periodically perform other steps after reading the state of charge.
In the battery charging control method of the application, the charging chip charges the battery 1 and the battery 2, when the charging chip determines that the charging voltage value of the battery 1 and the battery 2 is larger than or equal to the cut-off voltage value and the charging current value is smaller than or equal to the cut-off current value for the first time, the charging chip stops charging and updates the charging state to be the charging completion, at the moment, the battery 1 is actually fully charged, the battery 2 is possibly not fully charged, so when the charging management module determines that the charging state is the charging completion and the cut-off times are 0, the cut-off times can be updated to 1 and MOS is disconnected, so that the charging channel between the charging chip and the battery 1 is disconnected, and the battery 1 is prevented from being charged again when the subsequent charging chip is charged again; when the MOS is disconnected and recharged, the recharging chip only charges the battery 2 because the recharging chip cannot charge the battery 1, and when the recharging chip determines that the charging voltage value for charging the battery 1 and the battery 2 is greater than or equal to the cut-off voltage value and the charging current value is less than or equal to the cut-off current value for the second time, the recharging chip stops charging and updates the charging state to be the charging completion, and at the moment, the battery 2 is fully charged, namely, the battery 1 and the battery 2 are fully charged; based on this, when the charging management module determines that the charging state is charging completion and the charge cut-off number is 1, the charge cut-off number may be updated to 2; in this way, in one-time charging, the electric quantity of the battery 1 and the electric quantity of the battery 2 are guaranteed to be full, capacity loss is avoided, and charging experience of a user is improved.
And the charging management module can also judge whether the electronic equipment is in a screen-off state, so that when the electronic equipment is in the screen-off state, related operations are conveniently executed, normal running of the charging flow of the charging chip to the battery 1 and the battery 2 in sequence can be ensured, and the situation that when the electronic equipment is in a screen-on state, related operations such as MOS disconnection are executed, and a charging channel of the first battery is in a disconnection state, so that the electronic equipment has larger power consumption and unstable operation can be avoided.
Based on the above description, the following describes in detail the battery charging control method provided by the embodiment of the application with reference to the drawings and application scenarios.
Referring to fig. 7, fig. 7 is a flowchart illustrating a battery charging control method according to an embodiment of the application.
As shown in fig. 7, the method for controlling the charging of the battery according to the embodiment of the present application may be divided into a plurality of stages, wherein one of the stages may be a recharging stage.
The recharging stage can be understood as a stage in which after the electronic device charges the battery 1 and the battery 2 through the charging chip, if the charger is not disconnected, the charging voltage value drops to a preset threshold value, and the charging management module can enable the charging chip to recharge the battery 1 and the battery 2; for example, S31-S34 as shown in FIG. 7.
S31, when the charging voltage value of the charging chip is reduced to a preset voltage value, recharging is started.
It should be understood that, after the charging chip charges the battery 1 and the battery 2, if the charger is not disconnected, the charging voltage value of the charging chip may be reduced to a preset voltage value along with the consumption of the electric quantity of the battery 1 and the battery 2, that is, the charging voltage value is less than or equal to the preset voltage value, so that the charging chip may start recharging again.
And S32, when the charging voltage value of the charging chip reaches the cut-off voltage value, and the charging current value reaches the cut-off current value, the charging of the battery 1 and the battery 2 is stopped, and the charging state is updated to be the charging completion.
The implementation of S32 is similar to that of S14 in the embodiment shown in fig. 6, and will not be described herein.
S33, the charging management module reads the charging state from the charging chip.
The implementation of S33 is similar to that of S15 in the embodiment shown in fig. 6, and will not be described herein.
S34, the charging management module judges whether the charging state is charging completion and whether the charge interception times are 2.
When the charging state is charging completion and the charge cut-off times are 2, the charging chip detects that the charging voltage value reaches the cut-off voltage value twice and the charging current value reaches the cut-off current value, the charging is stopped twice, and the updated charging state is charging completion twice.
When the charging state is not charging completion, whether or not the number of times of charge cut is 2, it indicates that the charging chip is charging the battery 1 and/or the battery 2.
When the charging state is that charging is completed and the charge interception times are 2, the charging management module does not execute any operation; when the state of charge is not charging completion, the charge management module waits for S33 to be executed again.
In the application, after the charging chip fully charges the battery 1 and the battery 2, if the charger is not disconnected, the charging voltage value of the charging chip can be reduced to a preset threshold value along with the consumption of the electric quantity of the battery 1 and the battery 2, and the charging chip can be re-charged again to ensure that the electronic equipment is completely charged once, and then the charger can be charged again when the charger is not disconnected, so that the electric quantity of the battery is always in a fully charged state, and the charging experience of a user is ensured.
Based on the above description, the following describes in detail the battery charging control method provided by the embodiment of the application with reference to the drawings and application scenarios.
Referring to fig. 8, fig. 8 is a flowchart illustrating a battery charging control method according to an embodiment of the application.
As shown in fig. 8, the method for controlling the charging of the battery according to the embodiment of the present application may be divided into a plurality of stages, wherein one of the stages may be a charging stop stage.
The charging stopping stage can be understood as a stage of connecting the MOS and stopping charging when the electronic equipment is on a screen and the charger is in place and the charging stopping times are 1, and connecting the MOS and stopping charging when receiving the information of disconnecting the charger; for example, S41-S47 as shown in FIG. 8.
S41, the power management service module sends a bright screen event.
The bright screen event is used for indicating that the display screen of the electronic device is bright.
The power management service module may send a bright screen event to the charge management module in a number of ways.
In some embodiments, the electronic device may register and monitor a bright screen event in a process of starting up or restarting, and when the bright screen of the display screen of the electronic device is monitored, the power management service module may send the bright screen event to the charging management module to notify the charging management module that the electronic device is bright screen.
In other embodiments, an off-screen application is included in the electronic device, and the off-screen application is capable of sending an on-screen event to the charge management module to notify the charge management module that the electronic device has been on-screen when the electronic device is on-screen.
It should be appreciated that an off-screen event of the electronic device may occur during a full charge phase or during a recharge phase.
S42, the charging management module judges whether the charger is in place or not.
After the charging management module receives the information of connecting the charger, the charging management module can determine that the charger is in place when the information of disconnecting the charger is not received.
After the charging management module receives the information of connecting the charger and receives the information of disconnecting the charger, the charging management module can determine that the charger is not in place.
While the charger is in place, the charge management module may perform S43; when the charger is out of place, the charge management module does not perform any operations.
S43, the charging management module judges whether the cut-off times are 1.
The implementation of S43 is similar to that of S25 in the embodiment shown in fig. 6, and will not be described herein.
When the charge cut-off number is 1, the charge management module executes S44; when the number of times of charge interception is not 1, no operation is performed.
S44, the charging management module connects the MOS and stops charging.
As can be seen from the description of fig. 6, in the complete charging stage, the charging management module updates the number of times of charge interception to 1, and when the charging management module is in the off-screen state, the step of switching off the MOS can be performed, and then if the electronic device is on-screen, the charger is on site, and if the electronic device is to be charged normally, the MOS is switched off to charge the battery 1.
Therefore, when the electronic device is on the screen, the charger is in place, and the number of times of charge interception is 1, the charge management module can execute the step of connecting the MOS, so that the subsequent electronic device can charge the battery 1 normally.
In addition, when the number of times of charge interception is 1, the charging voltage value of the charging chip has reached the cut-off voltage value, and the charging current value has reached the cut-off current value, the charging of the charging chip is stopped, and the charging state is updated to be the charging completion.
In the complete charging stage, if the charging management module performs the step of disconnecting the MOS and the step of connecting the MOS, if the electronic equipment is on the screen, the charger is on site, and when the number of times of charge interception is 1, the MOS is in a connection state, and the electronic equipment can keep the MOS connection state.
The implementation of S44 is similar to that of S27 in the embodiment shown in fig. 6, and will not be described herein.
S45, judging the charging state and the cut-off times.
The implementation of S45 is similar to that of S20 in the embodiment shown in fig. 6, and will not be described herein.
S46, the charging management module receives the information of disconnecting the charger.
Wherein, S44 or S45 and S46 have no timing relationship.
It should be appreciated that the receipt of the information to disconnect the charger by the electronic device may occur during the full charge phase or during the recharge phase.
The electronic device may receive the information of disconnecting the charger in various manners.
In some embodiments, the charger is a wired charger, the charger is inserted into a charging interface of the electronic device through a charging interface of the charger, and the charging management module may receive information of disconnecting the charger when the charging interface of the charger is disconnected from the charging interface of the electronic device.
In other embodiments, the charger is a wireless charger, the electronic device is placed at a charging coil position of the wireless charger, and the charging management module may receive information to disconnect the charger when the electronic device moves out of the charging coil position of the wireless charger.
And S46, the charging management module updates the cut-off times to 0 and connects the MOS.
When the information of disconnecting the charger is received, the charging is ended, so that the charging management module can update the charge interception times to 0, and the related operation can be continuously executed according to the charge interception times when the next charging is performed.
And when receiving the information of disconnecting the charger, the charging management module can also connect the MOS, so that the charging chip can normally charge the battery 1 when the information of the charger is received next time.
It should be noted that, after the charging management module receives the information of disconnecting the charger, if the electronic device is on the screen, then the electronic device is on the screen, at this time, if the charging management module receives the information of connecting the charger, the charging chip can charge the battery 1 and the battery 2, and when the charging voltage value of the charging chip reaches the cut-off voltage value and the charging current value reaches the cut-off current value, the charging chip determines that the cut-off condition is satisfied, and can stop charging the battery 1 and the battery 2 together.
In addition, when the charging management module receives the information of the connection charger, if the electronic device is in the bright screen state, at this time, the charging chip can charge the battery 1 and the battery 2, and when the charging voltage value of the charging chip reaches the cut-off voltage value and the charging current value reaches the cut-off current value, the charging chip determines that the cut-off condition is met, and the charging of the battery 1 and the battery 2 can be stopped together.
In the application, when a screen-on event is received, the charging management module can determine whether the charger is in place, so that the charging management module can execute related operations when the charger is in place; since the charging management module can update the charge interception times to 1 and disconnect the MOS after the charging chip stops charging for the first time, that is, when the charge interception times are 1, the charging chip stops charging and the MOS is in a disconnected state, therefore, when the electronic equipment is on-screen and the charger is on site, and when the charge interception times are 1, the MOS can be connected, and the situation that the charging chip cannot charge the battery 1 when the electronic equipment is in the on-screen state can be avoided.
In addition, when the information of disconnecting the charger is received, it may be determined that the charging is finished, and the charging chip does not charge the battery 1 and the battery 2 any more, so that the charging management module may update the number of times of charging interception to 0, so that after the information of connecting the charger is received next time, it is possible to continuously execute related information according to the number of times of charging interception.
In addition, when receiving the information of disconnecting the charger, the charging management module can also connect the MOS so that a charging path between the charging chip and the battery 1 is connected, and thus, the charging chip can be ensured to charge the battery 1 normally when the information of the charger is received next time.
Based on the foregoing embodiments, a method for controlling charge of a battery according to the present application is described below.
Illustratively, the present application provides a method of controlling charging of a battery.
For convenience of explanation, the charge control method of the battery of the present application may be performed by the electronic device in fig. 2.
The electronic equipment comprises two batteries, namely a first battery and a second battery, wherein the first battery and the second battery are connected in parallel. The electronic equipment also comprises a charging chip, wherein the charging chip is used for charging the first battery and the second battery; the first battery is connected in series with the charging chip, and the second battery is connected between the first battery and the charging chip.
