Fig. 5 is a schematic diagram of a system module of a charging control method according to an embodiment of the present application.

Referring to fig. 5, the system includes a scene recognition module, a control module, and a system power consumption calculation module.

In this embodiment, the scene recognition module is deployed in the application layer shown in fig. 4 in the form of an application, and the scene recognition module communicates with the kernel layer through a hardware abstraction layer interface definition language (HAL interface definition language, HIDL) interface, or the JNI interface communicates with the application layer. The scene recognition module is used for acquiring various target parameters.

The system power consumption calculation module is arranged in the kernel layer, and can acquire charging parameters of the electronic equipment, such as charger input current, charger input voltage, input voltage of a battery, input current and the like, through the kernel layer. The system power consumption calculation module can calculate the system power consumption according to the charging parameters and transmit the system power consumption to the scene recognition module through the HIDL interface. The scene recognition module can match corresponding scenes according to the target parameters, and transmits charging strategies corresponding to the scenes to the control module through Java local interfaces (Java Native Interface, JNI).

And controlling the charging power through the HIDL interface according to the calculated charging parameters.

The following describes a charging control method provided by the embodiment of the present application by taking an example that the charging control method is applied to the electronic device 100 shown in fig. 1 or fig. 2 as a mobile phone, where a hardware architecture of the electronic device 100 may refer to fig. 3, a software architecture may refer to fig. 4, and a system module may refer to fig. 5.

Fig. 6 is a flowchart of a charging control method according to an embodiment of the present application.

Referring to fig. 6, the charge control method includes:

s601, determining that the electronic equipment is in a bright screen state and is in a charging state.

In a possible implementation manner, referring to the system module shown in fig. 5, the scene recognition module may acquire the target parameter once every preset time period. When the charging state identifier in the target parameter indicates that the electronic equipment is in a charging state and the bright screen state identifier indicates that the electronic equipment is in a bright screen state, the electronic equipment can be determined to be in the bright screen state and the charging state. The preset duration may be 1 second, 3 seconds, 5 seconds, or 10 seconds, which is not limited herein.

Or if the target parameter does not include the charging state or the screen-bright state, the electronic equipment can be determined to be in the screen-bright state by whether the foreground application can be acquired or not. For example, if the foreground application can be acquired, the application indicating that the foreground is active may determine that the electronic device is in the bright screen state.

If the charging current or the charging voltage is detected in the received system power consumption calculation module, the electronic equipment can be determined to be in a charging state. That is, if there is a foreground application and there is a charging current or charging voltage, it may be determined that the electronic device is in both the on-screen state and the charged state.

S602, acquiring target parameters, and determining a target charging strategy according to the target parameters.

In some possible implementations, the acquisition of the target parameters may be implemented by a scene recognition module shown in fig. 5.

Fig. 7 is a schematic structural diagram of a scene recognition module according to an embodiment of the present application.

In one possible implementation, referring to fig. 7, the target parameter may include at least one of a type of foreground application, a first temperature of the electronic device, and a system power consumption of the electronic device. Alternatively, a load of a System On Chip (SOC), a current power, an ambient temperature, a charger type, and the like may be included. The first temperature of the electronic device, the system power consumption of the electronic device, the load of the SOC, the current electric quantity, the charger type, and other parameters may be acquired by the scene recognition module from the kernel layer through the HIDL interface. Parameters such as the type of foreground application, the ambient temperature and the like can be acquired after the scene recognition module JNI interface is communicated with the application program layer.

By way of example, the types of foreground applications may include video class (denoted type 1), browser class (denoted type 2), instant messaging class (denoted type 3), game class (denoted type 4), and so forth. The first temperature of the electronic device may be a temperature of a processor of the electronic device, a front case temperature (case temperature), or a battery temperature, etc. The charger type may include wired charging, wireless charging, quick charging, and the like. The front shell temperature refers to the temperature of a mobile phone screen.

For example, the front shell temperature of the electronic device is acquired, and the temperature data can be acquired through at least one temperature sensor arranged around the screen of the electronic device. When a plurality of temperature sensors are disposed around the screen of the electronic device, the front case temperature of the electronic device may be an average value of a plurality of temperature data acquired by the plurality of temperature sensors.

For another example, the ambient temperature may be acquired by a temperature sensor provided by the electronic device itself, or may be acquired by an intelligent device connected to the electronic device. If the electronic equipment is connected with the intelligent air purifier, the intelligent air conditioner and other equipment through a network, the electronic equipment can acquire the ambient temperature acquired by the intelligent air purifier or the intelligent air conditioner as the ambient temperature of the electronic equipment.

It should be noted that, since the battery voltage in the mobile phone is unchanged, the change of the system power consumption and the current are in a linear relationship, and the system power consumption can be represented by the current. In the present application, system power consumption is characterized by current in milliamp (mA)

In one possible implementation manner, multiple sets of data may be acquired first, where each set of data includes a charging policy and reference information, and multiple reference information and target parameters in the multiple sets of data are used to determine the charging policy.

As an example, the reference information may include at least one of a target type of the foreground application, a temperature interval of the electronic device, and a system power consumption interval of the electronic device.

In one possible implementation, each set of data may correspond to a charging scenario. That is, each charging scenario corresponds to reference information and a charging policy in one set of data, in other words, the reference information and the charging policy in each set of data represent one charging scenario. When multiple sets of data are stored, the data can be stored in the field Jing Yuzhi library in the form of a charging scene.

As an example, the charging scenario may be stored by one JS object profile (JavaScript Object Notation, JSON) file or a fragment of the JSON file. For example, multiple charging scenarios may be recorded in one JSON file, where each charging scenario is a piece of code in the JSON file. Alternatively, a set of data corresponding to each charging scenario may be separately recorded in one JSON file.

As an example, multiple sets of data corresponding to multiple charging scenes may be recorded in one JSON file, where one JSON file included in the scene prefabricated library may be stored locally in the electronic device, or may also be stored in the cloud through a distributed storage system.

In another example, when a plurality of charging scenes are recorded individually in a plurality of JSON files, the scene prefabricated library includes the plurality of JSON files. The JSON file may be stored partially locally on the electronic device and partially in the cloud via a distributed storage system. Alternatively, all JSON files may be stored locally on the electronic device or stored at the cloud.

In a possible implementation manner, according to the target parameter and the multiple sets of data, determining a charging strategy corresponding to the reference information matched with the target parameter in the multiple reference information as a target charging strategy.

As an example, after acquiring the JSON file from the local or cloud, multiple sets of data corresponding to multiple charging scenes may be extracted first.

In one possible implementation, when the target parameter includes a system power consumption of the electronic device, acquiring the system power consumption may first acquire an output voltage and an output current of a charger connected to the electronic device, and an input voltage and an input current of a battery of the electronic device.

Then, the system power consumption of the electronic device can be determined according to the product of the output voltage and the output current of the charger connected to the electronic device, the product of the input voltage and the input current of the battery of the electronic device, and the charging efficiency.

As an example, the system power consumption in the above implementation may be obtained by a system power consumption calculation module.

Fig. 8 is a schematic structural diagram of a system power consumption calculation module according to an embodiment of the present application.

Referring to fig. 8, the system power consumption calculation module includes a charging chip efficiency calculation, a system power consumption collection, and filtering. The efficiency of the charging chip is the ratio of the electric quantity output during the discharging period of the charging chip to the electric quantity required by the charging of the charging chip to restore to the full-charge state. For example, it can be calculated by the following formula:

wherein I is _out For the output current during the discharging period of the charging chip, T _out Is the time to discharge to the off-voltage. I _in For charging current, T _in Is the charging time.

The charging chip efficiency may be calculated from historical charging data of the electronic device. When the historical charge data amount of the electronic device is insufficient, the charge chip efficiency set in advance according to the charge chip model may be used.

The single system power consumption acquisition can firstly acquire the output voltage and the output current of a charger connected to the electronic equipment, and the input voltage and the input current of a battery of the electronic equipment. The system power consumption of the electronic device is the product of the output voltage and the output current of the charger connected to the electronic device, and the product of the input voltage and the input current of the battery of the electronic device is subtracted, and then the charging efficiency is multiplied.

In one possible implementation, the system power consumption may be represented by a current, and the system power consumption of the electronic device is the product of the output voltage and the output current of the charger connected to the electronic device, and the product of the input voltage and the input current of the battery of the electronic device is subtracted, divided by the input voltage of the battery of the electronic device, and then multiplied by the charging efficiency.

In this embodiment, the single system power consumption acquisition may be calculated by the following formula:

the VBUS is an output voltage of the charger connected to the electronic device (i.e., a voltage of the charger input to the electronic device), and IBUS is an output current of the charger connected to the electronic device (i.e., a current of the charger input to the electronic device). VBAT is the input current (i.e., charging current) of the battery of the electronic device, IBAT is the input voltage (i.e., charging voltage) of the battery of the electronic device.

In one possible implementation, the system power consumption cannot be accurately expressed due to possible errors in a single system power consumption acquisition. Therefore, the system power consumption can be obtained by adopting a preset filter to filter the system power consumption of the electronic equipment acquired for multiple times in a preset period.

As an example, the filter may be an infinite impulse response (Infinite Impulse Response, IIR) filter, a moving average filter, or the like.

For example, when a moving average filter is used and the period is 10, the system power consumption is set to x, and the system power consumption collected 10 times historically is [ x ] _n-9 ，x _n ]The system power consumption can be calculated by the following formula:

in a possible implementation manner, after the target parameter is obtained, the reference information corresponding to each charging scene is obtained, the target parameter is compared with each reference information, when the target parameter is completely matched with one reference information, the charging scene corresponding to the reference information is determined to be the target charging scene, and the charging strategy of the target charging scene is the target charging strategy.

Through the charging scene that a plurality of target parameters match, the charging strategy that current electronic equipment needs can be accurate judgement, the temperature of control electronic equipment that charges according to this charging strategy can be more accurate, charging efficiency is guaranteed simultaneously.

In some possible implementations, the target charging policy may include a target temperature of the electronic device, a range of first charging parameters, a temperature control mode, a first threshold.

When the first charging parameter is obtained by the control module target charging strategy, the target charging strategy may be input to the control module. In this case, the target charging policy may also include module configuration parameters. The module configuration parameters are used to configure the control module.

As an example, when the control module is a proportional-integral-derivative (PID) module, the target temperature of the electronic device is the temperature maintained by the electronic device after the PID control module intervenes. The first threshold is the upper temperature limit of the electronic device, namely the highest temperature reached by the electronic device after the intervention of the PID control module, and when the temperature of the electronic device is greater than or equal to the upper temperature limit, the current charging strategy is not applicable any more. The range of the first charging parameter is a limitation of the PID module to output the first charging parameter, so as to prevent the first charging parameter output by the PID module from being too large or too small. The module configuration parameters comprise module operation time length and proportion adjustment parameters K _p Integral regulating parameter K _i Differential adjustment parameters. The temperature control mode may then comprise a step or a linear type.

For example, the target parameters include foreground application type (type 1), system power consumption (700 mA), current power (35%), shell temperature (27 ℃) and ambient temperature (25 ℃).

And 3 charging scenes are acquired, namely a charging scene 1, a charging scene 2 and a charging scene 3. The charging scene 1 comprises reference information 1 and a charging strategy 1, the charging scene 2 comprises reference information 2 and a charging strategy 2, and the charging scene 3 comprises reference information 3 and a charging strategy 3.

As an example, the reference information is specifically:

reference information 1: the shell temperature is less than or equal to 35 ℃, and the application types of the foreground are type 1, system power consumption [600, 700] mA, battery power [0, 20]%, and environment temperature [0, 33 ℃.

Reference information 2: the shell temperature is less than or equal to 35 ℃, and the application type of the foreground is type 2, the system power consumption is 300, 600 mA, the battery power is 0, 40 percent, and the environment temperature is 0, 33 ℃.

Reference information 3: the shell temperature is less than or equal to 35 ℃, and the application types of the foreground are type 1, system power consumption [600, 800] mA, battery power [0, 40]%, and environment temperature [0, 30] ℃.

Wherein, the target parameter can be matched with a plurality of reference information in sequence. For example, the target parameter is compared with the reference information 1, and the comparison result is that the battery power in the target parameter is not matched with the reference information 1. And then comparing the target parameter with the reference information 2, wherein the comparison result is that the foreground application type and the system power consumption range in the target parameter are not matched with the reference information 2. Finally, the target parameter is compared with the reference information 3, and the comparison result is a complete match. Then charging scenario 3 is the target charging scenario and charging strategy 3 is the target charging strategy.

As an example, when the control module is a PID control module, the target temperature of the electronic device, the module configuration parameter, the temperature control mode, the upper temperature limit of the electronic device, and the like may be included in the charging policy 3. In the module configuration parameters, the operation time of the PID module can be 600 seconds, and the proportion adjustment parameter K _p = 5500.0, integral adjustment parameter K _i =28.0 and differential adjustment parameter K _d =0.0. The temperature control mode can be a step-type temperature rise, the target temperature of the electronic equipment is 37 ℃, and the upper temperature limit of the electronic equipment is 37.5 ℃.

In another example, the target parameters include foreground application type (type 2), system power consumption (400 mA), current power (30%), shell temperature (29 ℃) and ambient temperature (24 ℃). The obtained charging scenario is the same as the above example.

The target parameter may be matched with multiple reference information in sequence. For example, the target parameter is compared with the reference information 1, and the comparison result is that the foreground application type, the battery power and the system power consumption range in the target parameter are not matched with the reference information 1. Then, the target parameter is compared with the reference information 2, and the comparison result is a complete match. Then charging scenario 2 is the target charging scenario and charging strategy 2 is the target charging strategy.

As an example, when the control module is a PID control module, the target temperature of the electronic device, the module configuration parameters, the temperature control mode, the upper temperature limit of the electronic device, and the like may be included in the charging policy 2. In the module configuration parameters, the operation time of the PID module can be 1200 seconds, and the proportion adjustment parameter K _p = 6500.0, integral adjustment parameter K _i =50.0 and differential adjustment parameter K _d =0.0. The temperature control mode can be a step type temperature rise, the target temperature of the electronic equipment is 36 ℃, and the upper limit of the temperature of the electronic equipment is 37 ℃.

In yet another possible implementation, when the field Jing Yuzhi library is stored in the cloud, the electronic device may upload the target parameters to the cloud, where the target charging policy is matched according to the target parameters. The electronic device may then receive the target charging policy sent by the cloud. The method for matching the target charging policy at the cloud according to the target parameter is the same as the method in the above embodiment, and will not be described herein.

S603, according to the target charging strategy, obtaining a first charging parameter through the control module and charging the electronic equipment according to the first charging parameter.

Fig. 9 is a schematic structural diagram of a control module according to an embodiment of the present application.

In one possible implementation, referring to S602 and fig. 9, the control module may be a PID control module. The PID module comprises proportional adjustment, integral adjustment and differential adjustment.

The proportional adjustment is to respond and control the deviation of the PID control module (i.e. the deviation between the feedback and the target) in real time in proportion, and once the deviation is generated in the feedback, the PID control module generates control to reduce the error. When the deviation is 0, the control action is also 0. Thus, the proportional control is adjusted based on the deviation, i.e., there is a differential adjustment.

The integral adjustment can memorize errors, is mainly used for eliminating static differences and improving the no-difference degree of the PID control module, the intensity of the integral action depends on an integral time constant, and the larger the integral time constant is, the weaker the integral action is, and otherwise, the stronger the integral action is.

The differential regulation can reflect the variation trend (variation rate) of the deviation, and can introduce an effective early correction signal into the PID control module before the deviation becomes too large, thereby accelerating the action speed of the system and reducing the regulation time.

When the control module is a PID control module, the scene recognition module can send the target charging strategy to the PID control module through the JNI interface. And after receiving the target charging strategy, the PID control module configures according to the target charging strategy and outputs a first charging parameter.

As an example, the first charging parameter may be a charging current. The feedback of the PID may be a shell temperature of the electronic device acquired after charging the electronic device according to the first charging parameter.

In one possible implementation manner, a charging module corresponding to the charging chip is arranged in the core layer, and the PID control module can transmit the first charging parameter to the charging module in the core layer through the HIDL interface to instruct the charging module to charge the battery according to the first charging parameter.

For example, the first charging parameter output by the PID control module is charging current 4.5A. The PID control module instructs the charging module in the kernel layer to charge the battery with a charging current of 4.5A through the HIDL interface.

In some possible embodiments, after the electronic device is charged according to the first charging parameter, the scene recognition module may further reacquire the target parameter every preset time period (e.g. 5 seconds). And stopping charging the electronic equipment according to the target charging strategy when the re-acquired target parameter is not matched with the reference information corresponding to the target charging strategy.

In one possible implementation manner, when the target parameters obtained again for multiple times do not match the reference information corresponding to the target charging policy, charging of the electronic device according to the target charging policy may be stopped.

For example, within 30 seconds, the scene recognition module reacquires 6 sets of target parameters, and if all of the 6 sets of target parameters do not match the reference information corresponding to the target charging policy, the charging of the electronic device according to the target charging policy is stopped.

And when the re-acquired target parameter is not matched with the reference information corresponding to the target charging strategy, indicating that the target charging strategy is not applicable any more. In this case, the charging of the electronic device according to the target charging policy is stopped. Then, the appropriate charging strategy can be continuously matched so as to further ensure that the charging efficiency is optimized under the condition that the equipment cannot overheat.

In a possible implementation manner, after S603, the method further includes:

s604, acquiring a second temperature of the electronic equipment.

In one possible implementation, the second temperature of the electronic device may be a shell temperature acquired after the first charging parameter is obtained by the control module and the electronic device is charged according to the first charging parameter.

S605, inputting a second temperature of the electronic equipment into the control module, and updating the first charging parameter by the control module according to the second temperature of the electronic equipment.

And S606, charging the electronic equipment according to the updated first charging parameters.

In one possible implementation manner, the control module is a PID module, and the second temperature of the electronic device may be used as a feedback to be input into the PID module, where the PID module updates the first charging parameter according to the second temperature of the electronic device, and charges the electronic device according to the updated first charging parameter.

For example, the second temperature of the electronic device is 35.5 ℃, and the PID module updates the first charging parameter to 2A according to the second temperature of the electronic device. Then, the PID control module instructs the charging module in the kernel layer to charge the battery with a charging current of 2A through the HIDL interface.

In a possible implementation manner, after S607, the method further includes:

s607, acquiring a third temperature of the electronic equipment.

In one possible implementation manner, after the electronic device is charged according to the updated first charging parameter, the scene recognition module may further acquire a third temperature of the electronic device at intervals of a preset period (for example, 1 second), where the third temperature of the electronic device may also be a shell temperature of the electronic device.

And S608, stopping charging the electronic equipment according to the target charging strategy when the third temperature is greater than or equal to the first threshold value.

In one possible implementation, when the third temperature of the electronic device is greater than or equal to the first threshold, it indicates that the target charging strategy has not been applied. In this case, the charging of the electronic device according to the target charging policy may be stopped.

For example, the first threshold may be an upper temperature limit (e.g., 37 ℃) of the electronic device. After the electronic device is charged according to the first charging parameter, the scene recognition module obtains that the temperature of the electronic device is 38 ℃. In this case, the charging of the electronic device according to the target charging policy may be stopped.

Or, the third temperature of the electronic device may be re-acquired multiple times, and if the third temperatures acquired multiple times are all greater than or equal to the first threshold, it is determined that the third temperature of the electronic device is greater than or equal to the first threshold. And stopping charging the electronic equipment according to the target charging strategy.

For example, the scene recognition module re-acquires the third temperature of the 5 electronic devices within 5 seconds, and if the acquired third temperatures of the 5 electronic devices are all greater than 37 ℃, the electronic devices are stopped from being charged according to the target charging strategy.

In yet another possible implementation, the third temperature of the electronic device may be determined to be greater than or equal to the first threshold when the average of the third temperatures of the electronic device is greater than or equal to the first threshold multiple times. And stopping charging the electronic equipment according to the target charging strategy.

For example, the scene recognition module re-acquires the third temperature of the 5 electronic devices within 5 seconds, and if the average value of the acquired third temperatures of the 5 electronic devices is 37.5 ℃ and greater than 37 ℃, the scene recognition module stops charging the electronic devices according to the target charging strategy.

When the third temperature of the electronic device is determined to be greater than or equal to the first threshold, the target charging strategy is indicated to be incapable of stabilizing the temperature of the electronic device. In this case, the charging of the electronic device according to the target charging policy may be stopped. And then, continuously acquiring target parameters, and matching a proper charging strategy to further ensure that the charging efficiency is optimized under the condition that the equipment cannot overheat.
