The charging state control method, the charging state control apparatus, the electronic device, and the readable storage medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

The charging state control method may be applied to the terminal, and may be specifically executed by hardware or software in the terminal.

The terminal includes but is not limited to a portable communication device such as a mobile phone or a tablet computer. It should also be understood that in some embodiments, the terminal may not be a portable communication device, but a desktop computer.

In the charging state control method provided in the embodiment of the present application, an execution main body of the charging state control method may be an electronic device or a functional module or a functional entity capable of implementing the charging state control method in the electronic device, the electronic device mentioned in the embodiment of the present application includes, but is not limited to, a mobile phone, a tablet computer, a camera, a wearable device, and the like, and the charging state control method provided in the embodiment of the present application is described below with the electronic device as the execution main body.

As shown in fig. 1, the state-of-charge control method includes: step 110 and step 120.

Step 110, acquiring a real-time electric signal of the powered device;

in this step, the real-time electrical signal may include: real-time charging current, real-time charging power, real-time charging voltage, etc., which are not limited herein.

The real-time electric signal is an electric signal extracted from the power supply equipment and can be embodied on the power supply signal of the power supply equipment.

It will be appreciated that the same technical effect can be achieved by replacing the current criterion with a power criterion or by assisting with the voltage criterion. Similarly, the same technical effect can be achieved by replacing the power criterion with the current criterion.

In the actual execution process, the real-time electric signals corresponding to the current power receiving equipment at the current acquisition time can be acquired at each acquisition time, and the acquired real-time electric signals are stored in a local or cloud database and can be called as required in the follow-up process.

For example, a real-time electrical signal during a time period T is acquired and recorded, wherein T > 0, as a window.

And step 120, determining that the powered device enters a charging suspension state and controlling the access module to enter a normally open state under the conditions that the real-time electric signal is smaller than the first electric threshold, the duration that the real-time electric signal is smaller than the first electric threshold exceeds the first time threshold and the real-time electric signal meets the jump starting detection condition.

In this step, the first electrical threshold and the first time threshold are both preset values.

The values of the first electrical threshold and the first time threshold may be user-defined.

Wherein the type of the electrical signal of the first electrical threshold should be consistent with the type of the real-time electrical signal.

The following describes a determination method for determining that the real-time electrical signal satisfies the detection condition of the jump start from two different implementation angles.

1. Determination based on change of front and back electric signals

In some embodiments, the determination that the real-time electrical signal satisfies the hop-on detection condition may be as follows: and determining that the real-time electric signal meets the jump starting detection condition under the condition that the change degree of the real-time electric signal is larger than the target range.

In this embodiment, the target range is a preset value.

The target range values may be user-defined.

The type of electrical signal corresponding to the target range should be consistent with the type of real-time electrical signal.

The variation degree is used for representing the maximum variation value of the real-time electric signal in the target time period, and the maximum variation value is used for representing the variation condition of the real-time electric signal in the target time period.

The target time interval is a time interval formed by forward pushing for a certain time length by taking the current acquisition time as an endpoint after the powered device is connected to the charging device.

In some embodiments, the degree of variation may be determined by:

the degree of change is determined based on a difference between the real-time electrical signal corresponding to the first target time and the real-time electrical signal corresponding to the second target time.

In this embodiment, the first target time and the second target time are acquisition times within the target time period, respectively.

When the second target time is the current acquisition time, the first target time may be any acquisition time before the current acquisition time in the target time period.

Or, when the second target time is the current collecting time, the first target time may be the collecting time corresponding to the largest real-time electrical signal in the target time period.

Or, the first target time may be the acquisition time corresponding to the largest real-time electrical signal in the target time period, when the second target time is the acquisition time corresponding to the smallest real-time electrical signal in the target time period.

The following describes a specific manner of determining the degree of change from the above three cases.

First, the change degree may be a change degree between a real-time electrical signal corresponding to the current acquisition time and a real-time electrical signal corresponding to a first target time, where the first target time is any acquisition time before the current acquisition time within a target time period.

In this embodiment, the target time is any one of the acquisition times within the target period.

For example, the change degree of the real-time electrical signal may be represented by a difference between the real-time electrical signal corresponding to the current collecting time and the real-time electrical signal corresponding to any previous collecting time, such as the change degree = Pi-Pcur; pi is a real-time electric signal corresponding to the first target moment; and Pmur is a real-time electric signal corresponding to the current acquisition moment.

Secondly, the change degree of the real-time electric signal can also be represented by the difference between the real-time electric signal corresponding to the current acquisition time and the maximum real-time electric signal in the target time period, such as the change degree = Pmax-Pcur; wherein Pmax is the largest real-time electric signal in a target time period; pcur is a real-time electrical signal.

Thirdly, the change degree of the real-time electric signal can also be represented by the difference value between the maximum real-time electric signal and the minimum real-time electric signal in the target time period, such as the change degree = Pmax-Pmin; wherein Pmax is the largest real-time electrical signal in a target time period; pmin is the smallest real-time electrical signal within the target time period.

Of course, in other embodiments, other manners of obtaining the variation degree of the real-time electrical signal may be adopted, and the present application is not limited herein.

The following describes an implementation of step 120 by taking the real-time electrical signal as the real-time charging power as an example.

And when the powered device is detected to be switched in or starts to be charged, acquiring and recording the real-time charging power Pcur in the period with the time length T as a window (namely the target time interval).

And if the real-time charging power Pcur at a certain acquisition moment is not less than the first electric threshold value P1, returning to the real-time charging power acquisition step.

If the real-time charging power Pcur at a certain collection time is smaller than the first electrical threshold P1, further determining whether the change degree of the real-time electrical signal is greater than a target range, for example, by a formula:

Pi–Pcur>P2

pi is a real-time electric signal corresponding to the target moment, namely the real-time electric signal corresponding to the real-time charging power target moment at any acquisition moment acquired during a window period with the current acquisition moment reverse duration being T; p2 is the target range.

And if the Pi-Pcur > P2 is not satisfied, returning to the real-time charging power acquisition step.

If Pi-Pcur > P2 is satisfied, it is further determined whether the real-time charging power Pcur is less than a first electrical threshold P1 and the duration of the maintenance exceeds a first time threshold t1.

If the current power jump condition of the powered device is determined to exist if the current power jump condition is less than a first electrical threshold P1 and the maintaining time exceeds a first time threshold t1, determining that the powered device is in a charging suspension state, and controlling the access module to be normally open.

And if the duration which is not less than the first electrical threshold P1 is not satisfied exceeds the first time threshold t1, returning to the step of collecting the real-time charging power.

Of course, in other embodiments, the three determination steps of the real-time electrical signal being smaller than the first electrical threshold, the duration of the real-time electrical signal being smaller than the first electrical threshold exceeding the first time threshold, and the change degree of the real-time electrical signal being greater than the target range may be performed simultaneously, or may be performed sequentially in any order, which is not limited herein.

It should be noted that only when all of the above three determination conditions are satisfied, it is determined that the powered device is in the charge suspension state, and the control path module is normally open.

2. Time-based determination

In some embodiments, the determination that the real-time electrical signal satisfies the hop-on detection condition may be as follows:

and determining that the real-time electric signal meets the jump starting detection condition under the condition that the continuous times that the real-time electric signal is greater than the sixth electric threshold are greater than the threshold.

In this embodiment, the sixth electrical threshold and the threshold are both preset values.

The values of the sixth electrical threshold and the threshold may be user-defined.

The following describes an implementation of this embodiment by taking a real-time electrical signal as a real-time charging power as an example.

As shown in fig. 5, the device accesses the real-time electrical signal collected after the charging is started, and the power jump detection function is in an off state.

When the real-time charging power > the sixth electrical threshold P3 is satisfied, the internal Counter starts counting;

when the real-time charging power > the sixth electrical threshold P3 is not satisfied, the internal Counter value is cleared.

And when the count of the internal Counter is greater than the threshold value N1, determining that the jump starting detection condition is met, and starting the power jump detection function at the moment.

After the power jump detection function is started, whether the real-time charging power is smaller than a first electric threshold value or not is judged, and the duration of the real-time charging power smaller than the first electric threshold value exceeds a first time threshold value.

And if the real-time charging power is continuously smaller than a first electrical threshold value P1 and the maintaining time exceeds a first time threshold value t1, determining that power jump occurs, and determining that the powered device is in a charging suspension state.

With continued reference to fig. 5, in some embodiments, the power jump detection function is turned off when the real-time charging power is continuously less than the seventh electrical threshold P7 and the duration of the hold time exceeds the eighth time threshold t 8.

Wherein the first time threshold t1< the eighth time threshold t8, the sixth electrical threshold P3 ≧ the seventh electrical threshold P7> the first electrical threshold P1.

According to the charging state control method provided by the embodiment of the application, whether the jump starting detection condition is met or not is judged through the continuous times that the real-time electric signal is greater than the sixth electric threshold, a large amount of data does not need to be recorded, the data storage space is saved, and the calculation efficiency is improved.

The inventor finds that, in the related art, the detection is mainly achieved by detecting output current/output voltage/output power, and if the output current/output voltage/output power is smaller than a certain threshold and lasts for a certain time, the device is considered to be full or not with power demand, so that an output path is closed. However, this technique has the following problems:

1) When the charging power is high, the environment temperature is high or the heat dissipation effect is poor, the over-high temperature of the powered device can cause the powered device to stop receiving energy, and the energy supplied by the power supply device can not be continuously received until the temperature of the powered device drops; during over-temperature, the output current/output power is almost zero.

2) Currently, part of powered devices are equipped with an intelligent charging mode, namely, the charging habit of a user is learned, and when a charging source is accessed for a long time, the time for receiving energy is intelligently distributed until the powered devices are fully charged; for this mode, the output current/output power is almost zero during the time the powered device stops accepting energy.

3) There are currently intermittent electrical devices, the energy supply required for their operation also being intermittent; the output current/output power is also almost zero when the powered device is in a suspended operation.

For the above situations, if the above method is still used to determine whether the powered device is fully charged or in a non-power demand, because the powered device is in a charging suspension state or an intermittent power consumption state, the output current/output power is almost zero, at this time, the device is erroneously identified as the fully charged/non-power demand, so that the output path is closed, the powered device is finally not fully charged or cannot be restarted, the charging effect is affected, and the user experience is also affected.

In the application, whether the jump starting detection condition is met is judged by comparing the change degree of the real-time electric signal with the second threshold value or by comparing the continuous times that the real-time electric signal is greater than the sixth electric threshold value, jump detection is started under the condition that the jump starting detection condition is determined to be met, and whether jump occurs is further detected.

When whether jumping occurs is detected, whether jumping occurs is judged based on the duration time that the real-time electric signal is smaller than the first electric threshold, the reduction condition of the electric signal caused by jumping or full power (in the constant-voltage charging stage, along with the rising of the electric quantity of the powered device, the charging current is in a slow reduction trend) can be effectively distinguished, and therefore whether jumping occurs in the electric signal is detected to distinguish that the powered device enters a full-charge state or enters a pause-charge state.

Under the conditions that the jump starting detection condition is met and jump occurs, the powered device is controlled to enter a charge suspension state, the influence of acquisition errors existing in the acquisition process on the result can be eliminated, and the detection is sensitive and high in detection precision.

According to the charging state control method provided by the embodiment of the application, the real-time electric signal of the powered device is judged by integrating multiple conditions such as whether the powered device meets a jump starting condition and whether the power device jumps or not, the suspended charging state and the full-power state of the powered device can be effectively distinguished, so that the accuracy and the precision of a judgment result are improved, and the method is suitable for intermittent power utilization equipment and has wide use scenes.

As shown in fig. 2, in some embodiments, after determining that the powered device enters the suspend-to-charge state, the method may further include:

determining that the powered device exits the charge suspension state under the condition that the real-time electric signal is greater than a second electric threshold and the duration is not less than a second time threshold;

a real-time electrical signal of the powered device is acquired.

In this embodiment, the second electrical threshold and the second time threshold are preset values.

The values of the second electrical threshold and the second time threshold may be user-defined.

Wherein the type of the electrical signal of the second electrical threshold should be consistent with the type of the real-time electrical signal.

The following describes an implementation of this embodiment by taking a real-time electrical signal as a real-time charging current as an example.

And under the condition that the powered device is in the charging pause state, if the real-time charging current is greater than a second electrical threshold I1 and the duration is greater than or equal to a second time threshold T2, determining that the powered device exits the charging pause state, and returning to the window data acquisition state taking T as the duration.

According to the charging state control method provided by the embodiment of the application, after the powered device is determined to be in the charging suspension state, changes such as real-time charging current of the powered device are continuously monitored, the state change of the powered device can be timely detected, corresponding steps are executed, the response timeliness is high, and the sensitivity is high.

With continued reference to fig. 2, in some embodiments, after acquiring the real-time electrical signal of the powered device, the method may further comprise:

under the condition that the real-time electric signal is smaller than a third electric threshold, the duration is not smaller than a third time threshold, and the real-time electric signal does not meet the target condition, determining that the powered device is in a full-power state, and controlling the access module to enter a closed state;

In this embodiment, the third electrical threshold and the third time threshold are preset values.

The values of the third electrical threshold and the third time threshold may be user-defined.

Wherein the type of the electrical signal of the third electrical threshold should be consistent with the type of the real-time electrical signal.

The following description will proceed with the implementation of this embodiment by taking the real-time electrical signal as the real-time charging current as an example.

As shown in fig. 2, in the state group 1, if the real-time charging current is smaller than the third electrical threshold I2 for a duration greater than or equal to the third time threshold t3, it is determined that the powered device is fully charged, and the control unit turns off the path module.

It should be noted that the full power detection path in this embodiment should have a lower priority than the power jump detection path.

That is, the full power detection process is executed only when at least one of the three conditions that the real-time electrical signal of the powered device is smaller than the first electrical threshold, the duration of the real-time electrical signal smaller than the first electrical threshold exceeds the first time threshold, and the degree of change of the real-time electrical signal is greater than the second threshold is not satisfied.

For example, when the target condition is satisfied simultaneously with "the real-time electrical signal is smaller than the third electrical threshold and the duration is not smaller than the third time threshold", the powered device should be preferentially controlled to enter the suspend-charging state.

According to the charging state control method provided by the embodiment of the application, whether the powered device enters the full-power state is further judged based on the magnitude, duration and the like of the real-time electric signal under the condition that the powered device is excluded from entering the suspended charging state, and the access module is controlled to be closed in time under the condition that the powered device is determined to enter the full-power state, so that the power consumption of the power supply device can be effectively saved, and the service life of a battery of the powered device is prolonged.

With continued reference to fig. 2, in some embodiments, after determining that the powered device enters the suspend-to-charge state, the method may further comprise:

and under the condition that the real-time electric signal is smaller than the fourth electric threshold and the duration is not smaller than the fourth time threshold, controlling a charging interface of the charging equipment connected with the powered equipment to enter a dormant state.

In this embodiment, the fourth electrical threshold and the fourth time threshold are preset values.

The values of the fourth electrical threshold and the fourth time threshold may be user-defined.

Wherein the type of the electrical signal of the fourth electrical threshold should be consistent with the type of the real-time electrical signal.

For example, when the powered device is in a state of suspending charging, if the real-time charging current is less than the fourth electrical threshold I3 and the duration is greater than or equal to the fourth time threshold t6, the charging interface connected to the powered device is controlled to enter the sleep state.

According to the charging state control method provided by the embodiment of the application, the charging interface is controlled to enter the dormant state when the powered device is determined to be in the state of charging suspension, so that the power consumption of the power supply device can be further saved.

With continued reference to fig. 2, in some embodiments, after controlling the charging interface of the charging device connected to the powered device to enter the sleep state, the method may further include:

In this embodiment, it can be understood that, in a case where different interfaces share the same power supply (including but not limited to direct current-direct current (DC-DC), alternating current-direct current (AC-DC) and low dropout regulator (LDO), and no power is directly delivered to the output interface through other power modules), when multiple interfaces operate simultaneously, there may be a difference in voltage levels of different interfaces requesting the fast charging protocol, and the interfaces cannot operate in the fast charging state simultaneously.

Under the condition that different interfaces share the same power supply, when the powered device is identified to be in the states of full charge, no power demand or unplugging and the like, the power supply path of the current charging interface can be closed, so that the other charging interfaces can work in the fast charging state to optimize power distribution.

In the application that different interfaces do not share the same power supply, different power supplies may be in different voltage levels, and when it is identified that the powered device is in a state of being full, having no power demand, or being pulled out, the power supply path of the current charging interface may be selected to be closed, and the power is released to the rest of online charging interfaces, or the power is directly released to the rest of online interfaces, so as to optimize power distribution.

The implementation of this embodiment will be described by taking the real-time electrical signal as the real-time charging current as an example.

For example, when the powered device is in a charging suspension state, if the real-time charging current is less than a fourth electrical threshold I3 and the duration is greater than or equal to a fourth time threshold t6, the charging interface connected to the powered device is controlled to enter a sleep state; and then judging whether the charging interface and other charging interfaces share the same power supply.

Under the condition that the power supply is not shared, the charging power occupied by the charging interface can be released to other charging interfaces, so that power distribution is optimized, and the overall charging efficiency is improved.

According to the charging state control method provided by the embodiment of the application, under the condition that different charging interfaces do not share the same power supply, the charging power corresponding to the charging interface entering the dormant state is released to other charging interfaces, so that power distribution can be optimized, and the overall charging efficiency is improved.

and controlling the charging interface to exit the dormant state under the condition that the real-time electric signal is greater than the fifth electric threshold and the duration is not less than the fifth time threshold.

In this embodiment, the fifth electrical threshold and the fifth time threshold are preset values.

The values of the fifth electrical threshold and the fifth time threshold may be user-defined.

Wherein the type of the electrical signal of the fifth electrical threshold should be consistent with the type of the real-time electrical signal.

For example, when the charging interface is in the sleep state, if the real-time charging current corresponding to the charging interface (i.e. the real-time charging current of the powered device connected to the charging interface) is suddenly greater than the fifth electrical threshold I4 and the duration time exceeds the fifth time threshold t7, the charging interface is controlled to exit the sleep state, and the pass module is kept in the normally-on state.

According to the charging state control method provided by the embodiment of the application, after the charging interface enters the dormant state, the real-time electric signal is continuously monitored so as to timely adjust the corresponding control strategy based on the change of the electric signal, and the method has the advantages of higher response timeliness and higher sensitivity.

With continued reference to fig. 2, in some embodiments, after controlling the powered device to enter the suspend-to-charge state, the method may further comprise:

and under the condition that the duration of the charging state is not less than the sixth time threshold, or the duration of the charging interface of the charging equipment connected with the powered equipment entering the sleep state is not less than the seventh time threshold, controlling the access module to enter the closed state.

In this embodiment, the sixth time threshold and the seventh time threshold are preset values.

The values of the sixth time threshold and the seventh time threshold may be user-defined.

For example, when the duration of the powered device being in the charging suspension state is greater than or equal to the sixth time threshold t4, or the duration of the charging interface being in the sleep state is greater than or equal to the seventh time threshold t5, the powered device is considered to be fully charged, the path module is forcibly turned off, the algorithm is reset, and the powered device is waited to be connected again or the powered device is waited to start charging again.

It should be noted that the priority of the timeout determination procedure provided in this embodiment is lower than the determination mechanism for resuming the powered device from the sampling state with the duration T as the window, but higher than the sleep mechanism procedure.

For example, in the case where "the real-time charging current is greater than the second electrical threshold I1 and the duration is greater than or equal to the second time threshold t2" coincides with "the charging suspended state duration > the sixth time threshold t4 or the duration in the sleep state > the seventh time threshold t5", the path "the real-time charging current is greater than the second electrical threshold I1 and the duration is greater than or equal to the second time threshold t2" is preferentially executed;

for another example, when the "real-time charging current is less than the fourth electrical threshold I3 and the duration is greater than or equal to the fourth time threshold t6" and the "duration of the charging pause state > the sixth time threshold t4 or the duration in the sleep state > the seventh time threshold t5" occur simultaneously, the path of the "duration of the charging pause state > the sixth time threshold t4 or the duration in the sleep state > the seventh time threshold t5" is preferentially executed.

According to the charging state control method provided by the embodiment of the application, the access module is controlled to be closed under the condition that the powered device is in the charging suspension state for a long time or the charging interface is in the dormant state for a long time through overtime judgment, so that the power consumption of the power supply device can be effectively saved, and the service life of the power supply device is prolonged.

In some embodiments, with continued reference to fig. 2, in state group 2, if a powered device unplugging is detected, then entering a device unplugged state is confirmed and a return is made to waiting for the powered device to be plugged in or waiting for the powered device to start charging.

The path for detecting the unplugged/unplugged state has the highest priority. That is, when it is determined that the powered device enters the device unplugged state, the current determination is directly ended, and a new execution flow is entered.

In some embodiments, with continued reference to fig. 2, after the control path module enters the shutdown state, the power receiving device may return to the standby state or the standby state, and enter a new execution flow.

The following describes an implementation of plug detection of a powered device.

In some embodiments, the connection state of the powered device and the charging interface may be detected by detecting the connection state of the CC line of the Type-C interface.

In some embodiments, a weak pull-up circuit and a weak pull-down circuit may be disposed on the Type-a interface DPDM line, and detect whether there is an external driver to determine the connection state of the powered device and the charging interface.

In some embodiments, whether the powered device starts charging may also be determined by charging current/charging power/whether there is a fast charge.

Of course, in other embodiments, the plugging detection and the detection of whether the detection device starts charging may be implemented in other manners, which is not limited in this application.

It should be noted that the method for determining whether the condition for detecting the jump-on is satisfied based on the number of consecutive times that the real-time electrical signal is greater than the sixth electrical threshold provided in the embodiments of the present application may be implemented by various means, such as executing the step by software program control, or may be implemented by a hardware circuit, and various changes may be made to the embodiments without departing from the principles and spirit of the present application.

The following describes an implementation manner of this embodiment by taking an example of a hardware circuit to implement the jump-on detection.

Fig. 6 illustrates a circuit configuration for implementing the jump-on detection condition determination.

The circuit is built by taking current as a criterion, and can realize partial algorithm functions.

Fig. 7 illustrates a sampling clock circuit Timer in which the sampling clock circuit generates a 50% duty cycle clock for sample timing.

Fig. 8 illustrates a main sampling circuit, in which the CSPs and CSNs are voltages across current sampling resistors, and this sampling information can be equivalently converted into an output current.

In the first half of the clock, S1 is closed, C1 is charged and the integration of the current will reflect the voltage level at hi _ det. S4 is closed, C2 is discharged, and lo _ det is clamped at 0.

In the second half of the clock, S3 is closed and hi _ det is clamped at 0. S6 is closed, C2 is charged and the integral of the current will be reflected in the voltage at lo _ det.

Fig. 9 illustrates a hi _ det determining circuit, when the voltage at the hi _ det point is greater than a threshold, it is considered that the large current and time required for power jump are satisfied, that is, conditions that the continuous times that the real-time electrical signal is greater than the sixth electrical threshold are greater than the threshold are satisfied, and the jump detecting function is turned on, and hi _ exist is set high.

Fig. 10 illustrates a transition determination enable signal circuit by which the transition detection function is enabled after hi _ exist is set high, and the transition detection signal is set high for a time period t 8. After t8 the transition detection function will be switched off. The real-time charging power is continuously smaller than a seventh electrical threshold P7, the maintaining time exceeds an eighth time threshold t8, and the circuit sets a sixth electrical threshold P3= a seventh electrical threshold P7.

FIG. 11 illustrates an lo _ det decision circuit that considers the low power required for a transition when lo _ det is less than a threshold. When the rising edge of the Timer occurs, the One Shot circuit generates a high level of 500ns, S7 is closed, and the judgment threshold of U2 is switched to a low-power threshold required by corresponding jump. When lo _ det is smaller than the threshold value, the low power required by the jump is considered to be met, namely the real-time electric signal is continuously smaller than a first electric threshold value P1 and the maintaining time exceeds a first time threshold value t1 criterion, the jump is considered to occur, and the powered device is in a charging suspension state.
