The present application provides an electronic device control method, which can be used to control various electronic devices. The electronic devices that can be used to control include but are not limited to: mobile energy storage batteries, mobile phones, computers, cars, etc.

Specifically, the electronic device control method provided in the present application is applied to a main control module in an electronic device. The main control module can be any one or more combinations of processors such as a microcontroller unit (MCU), an application processor (AP) and/or a neural-network processing unit (NPU). When the above-mentioned electronic device is provided with a battery management system (BMS), the above-mentioned main control module can be arranged on the BMS of the above-mentioned electronic device.

Referring to FIG1, a schematic diagram of the organizational structure of the internal modules of an electronic device in an embodiment of the present application, the electronic device of the present application includes a battery module and a plurality of working modules in addition to a main control module. The working module may include a power conversion module of the electronic device, a wireless network module of the electronic device, a storage module of the electronic device, or other types of modules, which are not limited here. In this embodiment, the working module refers to a module that can realize a preset function and needs to consume power. The battery module is connected to the main control module in communication and accepts the control scheduling of the main control module. Each working module is also connected to the main control module in communication and accepts the control scheduling of the main control module.

Referring to FIG. 2 , which is a flow chart of a device control method in an embodiment of the present application, the device control method provided by the present application includes:

Step S110: obtaining an initial power parameter value of the battery module.

In the embodiment of the present application, the initial power parameter value of the battery module is mainly used to describe the power value at the time when the device is powered on (also referred to as the initial moment). It should be noted that the battery module always has a minimum power value during the discharge or charging process. The battery module will not release the power to 0 when discharging, and it will stop discharging after releasing to the minimum power value. Among them, the initial power parameter value of the battery module can be the remaining power corresponding to the time when the device is powered on, or it can be the state of charge SOC (State of Charge) at the time when the device is powered on, that is, the ratio between the remaining power and the full power of the battery module. For example, in the scenario where the energy storage power supply is charged by the mains, the above-mentioned initial power parameter value can be the state of charge displayed by the energy storage power supply when it is connected to the mains for charging. Powering on an electronic device usually means that the device is in the on state, at which time the electronic device can be in working state or in sleep state.

Step S120: in each preset period, the accumulated power parameter value independently calculated by each working module is obtained through communication.

In the embodiment of the present application, each working module independently calculates the corresponding module power parameter value. The cumulative power parameter value is configured to characterize the total power flowing into or out of the working module after the working module is powered on, that is, from the initial moment. The cumulative power parameter value can be directly the cumulative power calculated by the working module through the ampere-hour integration method, or it can be the ratio of the cumulative power to the power of the battery module at full power.

The length of the preset period can be set as needed, for example, according to the sampling period of each working module. The preset period can be greater than the sampling period of each working module, or can be equal to the sampling period of each working module. Usually, the preset period can be set to millisecond level.

In each preset cycle, the main control module establishes communication with each working module, and then obtains the cumulative power parameter value independently calculated by each working module. Since the working module can monitor its own status in real time and will not be interfered by other factors, such as data loss due to communication anomalies, which will affect the accuracy of the cumulative power parameter value. Therefore, as long as the main control module can establish communication with the working module normally, what is obtained must be the accurate cumulative power parameter value measured by the working module during the cumulative metering cycle. The main control module will not be unable to obtain accurate power parameter values due to communication anomalies in the middle, so it has stronger timeliness and data accuracy.

In the related technology, the electronic device obtains the instantaneous current parameter value on each working module in real time through the main control module, and then calculates the remaining power or charge state based on the instantaneous current parameter value. Once there is a communication abnormality between the main control module and the corresponding working module, the instantaneous current parameter of the abnormal device cannot be obtained, so that the remaining power or charge parameter calculated by the main control module will have a large deviation from the actual value, and cannot be automatically calibrated after the communication is restored. In this embodiment, each time what is obtained is the cumulative power parameter value calculated independently by each working module. Even if there is a communication abnormality in a certain period of time, resulting in a certain calculation deviation of the main control module, it can be restored to the actual power value after the communication is restored, thereby improving the reliability and accuracy of the data.

Step S130: Obtain a first state of charge of the device according to the initial power parameter value and each accumulated power parameter value.

In the embodiment of the present application, after the main control module obtains the initial power parameter value of the battery module and the cumulative power parameter value of each working module in each preset cycle, it combines the initial power parameter value and the cumulative power parameter value to obtain the first state of charge of the device. Since the cumulative power parameter value of each preset cycle obtained by the working module independently calculated has a stronger timeliness and can more timely and accurately reflect the power value of the working module in each preset cycle, the first state of charge of the electronic device obtained on this basis also has a stronger timeliness, so that it can more timely and accurately reflect the state of charge of the electronic device in each preset cycle.

Step S140: When the absolute value of the difference between the first state of charge acquired in the current cycle and the first state of charge acquired in the previous cycle is greater than a first preset threshold, it is determined that there is an abnormality in the communication connection between at least one working module and the main control module.

It is understandable that when the device is working normally, the first state of charge usually does not change suddenly. For example, when the device is stably loaded, the power consumed or transmitted by each working module in each preset cycle is stable, so the absolute value of the difference between the first state of charge obtained in two adjacent cycles will satisfy such a stable relationship, which can be reflected by the first preset threshold value, so that when the absolute value of the difference is less than the first preset threshold value, it can be considered as a smooth change, not a sudden change. When the electronic device suddenly increases the load or suddenly increases the power supply, the current of the electronic device will not change suddenly, but will gradually increase from small to large through strategies such as slow start. And the preset cycle belongs to the millisecond level, so it can also ensure that the first state of charge finally obtained will not change suddenly. The first state of charge is also a smooth change process, but the slope of the change is steeper than that of light load or no load, but it will not change suddenly. In addition, when a certain working module switches from the working state to the standby state or the non-working state, its communication with the main control module is still in the normal communication state, so that the working module will still report the accumulated power parameter value to the main control module, so that no sudden change will occur.

If the first state of charge changes suddenly, it means that the communication connection between the main control module and some working modules is abnormal, resulting in the main control module being unable to receive the accumulated power parameter value of these working modules. Since the accumulated power parameter value is a value accumulated from the initial moment, the accumulated power parameter value is much larger than the amount of power change in each preset cycle, resulting in a large deviation in the calculation of the first state of charge. Therefore, a first preset threshold value can be pre-set for the absolute value of the difference between the first state of charge obtained in the current cycle and the first state of charge obtained in the previous cycle. If the absolute value of the difference is greater than the first preset threshold value, it means that the first state of charge obtained in the current cycle has changed suddenly, and then it is determined that there is an abnormality in the communication connection between at least one working module and the main control module.

Among them, the first preset threshold should be reasonably set by those skilled in the art, and the setting of the first preset threshold must be greater than the change value of the smooth change of the first state of charge. For example, if the power currently carried by the electronic device has not changed, the operation of each working module and the communication between each working module are also normal, the change value of the first state of charge of the electronic device in each preset cycle is 0.1%, then the first preset threshold can be set to 0.3% or 0.5%, so that the abnormal communication situation can be accurately judged, and the sudden change of the load of the electronic device can also meet the situation where the first state of charge fluctuates to a certain extent. The first preset threshold can be a fixed value, or it can be set according to the operating state of the electronic device. For example, the main control module can determine the power consumption of each working module in a normal state in a preset cycle according to the current charging and discharging state, the power supply capacity of the power supply, or the required power of the load, and determine the corresponding first preset threshold according to the power consumption. It can be understood that the setting of the above first preset threshold is only for example, and is not limited to the scope of protection of this application.

In one embodiment, after obtaining the first state of charge of the electronic device according to the initial power parameter value and each accumulated power parameter value, the method further includes:

When the absolute value of the difference between the first state of charge acquired in the current cycle and the first state of charge acquired in the previous cycle is less than or equal to the first preset threshold, it is determined that the communication connection between each working module and the main control module is normal.

In this embodiment, as mentioned above, when the electronic device is working normally, its first state of charge should change smoothly. Under normal conditions, the absolute value of the difference between the first states of charge in every two adjacent cycles is always less than or equal to the first preset threshold, such as the aforementioned 0.3%.

In some embodiments, when the main control module determines that the communication connection between itself and each working module is normal, it can be considered that the accumulated power value of each working module currently obtained by itself is accurate data, and the first state of charge calculated based on these data is also trustworthy. The main control module will determine the first state of charge obtained in the current cycle as the display state of charge of the current cycle and display it.

In this embodiment, the main control module can determine that the communication connection between each working module and the main control module is normal when the absolute value of the difference between the first charge states obtained in two adjacent cycles is less than or equal to a first preset threshold value, and on this basis, use the first charge state calculated in the current cycle as the display charge state to accurately display the power of the electronic device in the current cycle.

Since the first state of charge of the electronic device has a stronger timeliness, it can more timely and accurately reflect the state of charge of the electronic device in each preset cycle. Therefore, based on the first state of charge, the main control module can more timely and accurately detect the abnormality of the communication connection between the working module and the main control module, so that the electronic device can more timely and accurately respond to the abnormality of the communication connection between the working module and the main control module.

In one embodiment, each accumulated power parameter value refers to the accumulated charge state, that is, the ratio between the accumulated power of each working module and the full power of the battery module, that is, the state of charge _SOCn . At this time, the main control module obtains the state of charge _SOCn output by each working module. Each working module calculates its own module power parameter value according to the following formula:

_SOCn ＝ _Fn /F*100％

Among them, _Fn represents the accumulated power of the nth working module, t represents the current moment, _In represents the current value obtained by the nth working module monitoring itself in real time during the time period of 0 to t (the time period of 0 to t may include one or more preset cycles, and the moment of "0" may represent the power-on moment of the device), _SOCn represents the state of charge of the nth working module, and F represents the full power of the battery module of the electronic device. It should be noted that the current _In is a parameter with a vector direction, so it can be determined whether the working module is currently charging the battery module or consuming the power of the battery module according to its current direction. When the battery module is charged using an external power supply, the direction of the current _In is negative, and vice versa.

Therefore, the initial power parameter value of the battery module obtained by the main control module is also the state of charge SOC _past of the battery module. The state of charge SOC _past represents the remaining state of charge of the electronic device in the past, that is, it can be understood as the remaining state of charge of the electronic device when it is powered on. The main control module calculates the first state of charge SOC _A of the device according to the following formula based on the state of charge SOC _past and the state of charge SOC _n output by each working module:

The sum of the states of charge of each working module output to the main control module is represented. By subtracting the initial state of charge SOC _past from the sum of the states of charge acquired in each preset cycle, the current first state of charge SOC _A of the electronic device can be obtained.

In another embodiment, the accumulated power _Fn calculated by each working module may be directly transmitted to the main control module as the accumulated power parameter value. In this case, the main control module needs to sum the accumulated power of each working module as needed to obtain the total accumulated power F _A of each working module, as shown in the following formula:

After the total accumulated power F _A of each working module is obtained, if the initial power parameter value obtained by the main control module is the initial remaining power F ₀ , the first state of charge SOC _A is calculated by the following formula:

In one embodiment, after determining that there is an abnormality in the communication connection between at least one working module and the main control module, the method further includes:

The working module that has not sent the accumulated power parameter value is detected, and the working module that has not sent the accumulated power parameter value is determined as a communication abnormality module.

In this embodiment, after determining that a communication anomaly occurs between the working module and the main control module, the main control module can track the module with the communication anomaly, and determine the module with no communication anomaly by detecting the working module that has not sent the cumulative power parameter value. Because under normal communication conditions, the working module with normal communication will send its own cumulative power parameter to the main control module at a certain interval period. Even if the working module does not work in the current cycle, it will periodically send the last calculated cumulative power parameter to the main control module. For example, the inverter module needs to perform inversion work in the first cycle, but does not need to perform inversion in the next cycle. However, as long as the communication of the inverter module is normal, the cumulative power parameter calculated in the first cycle will still be sent to the main control module in each subsequent cycle. When the communication of the working module is abnormal, that is, it will not send its own cumulative power parameter to the main control module, the main control module will determine the working module that has not received the cumulative power parameter as an abnormal module through investigation.

In some embodiments, when the working module sends its own accumulated power parameters to the main control module, it may be sent in the form of a signal carrying the accumulated power parameters. Therefore, the working module may attach a number pointing to itself when sending the signal. For example, the inverter module is numbered 01, and the heat dissipation module is numbered 02. When the main control module receives a signal carrying the number 01, it believes that there is no communication failure in the inverter module. When it does not receive a signal carrying the number 02, it identifies the heat dissipation module as a communication abnormality module. It is understandable that the way the main control module detects the working module that has not sent the accumulated power parameter value may be other communication judgment methods, and is not limited to the examples in the above embodiments. Those skilled in the art may make appropriate settings according to actual needs, which will not be repeated here.

In one embodiment, after determining that there is an abnormality in the communication connection between at least one working module and the main control module, the electronic device control method provided in the present application further includes: generating prompt information, and the prompt information is configured to prompt that there is an abnormality in the communication connection.

In this embodiment, after determining that there is an abnormality in the communication connection between at least one working module and the main control module, in order to remind the host computer of the electronic device or the user of the electronic device, the main control module generates a prompt message for prompting that there is an abnormality in the communication connection. Among them, if it is to remind the host computer, the main control module can generate an agreed error code as a prompt message in accordance with the agreement with the host computer, thereby reminding the host computer that there is an abnormality in the communication connection. If it is to remind the user, the main control module can generate text or voice as a prompt message, thereby reminding the user that there is an abnormality in the communication connection. The above prompt information can also be embodied in the form of light, vibration, etc., and the embodiment of the present application does not limit the specific form of expression of the above prompt information.

In one embodiment, after determining the working module that does not send the cumulative power parameter value as a communication abnormality module, the method further includes:

The accumulated power parameter value most recently sent by the communication abnormality module is used as the accumulated power parameter value corresponding to the communication abnormality module obtained in the current cycle.

The first state of charge of the current cycle is updated according to the initial power value and each accumulated power parameter value obtained in the current cycle.

In this embodiment, after determining that a communication abnormality module appears in the electronic device, in order not to seriously affect the calculation of the first state of charge of the entire electronic device, after determining that the communication abnormality module is present, the main control module can use the most recently sent cumulative power parameter of the communication abnormality module as the cumulative power parameter value corresponding to the communication abnormality module obtained in the current cycle, even if the cumulative power parameter of the communication abnormality module cannot be obtained temporarily due to a communication failure. For example, after determining that the heat dissipation module is the communication abnormality module in the current cycle, the main control module uses the cumulative power parameter of the heat dissipation module obtained in the nearest cycle as the cumulative power parameter of the heat dissipation module in the current cycle.

In this way, the main control module can have the accumulated power parameters of each working module (including the communication abnormality module) in the electronic device, and calculate the new first charge state based on the initial power value and the accumulated power parameters of the aforementioned working modules (including the communication abnormality module) to update the first charge state in the current cycle.

In this embodiment, by replacing the accumulated power parameters most recently sent by the communication abnormality module with the accumulated power parameters of the communication abnormality module in the current cycle, the gap in data loss caused by the communication abnormality is filled, thereby avoiding the problem of large errors in the main control module calculating the first charge state of the electronic device.

In one embodiment, displaying the first state of charge acquired in the current cycle includes:

Get the displayed state of charge for the last cycle.

When the absolute value of the difference between the first state of charge acquired in the current cycle and the displayed state of charge in the previous cycle is less than or equal to the second preset threshold, the first state of charge acquired in the current cycle is determined as the displayed state of charge in the current cycle and displayed.

The second preset threshold is set to provide users with a better user experience, so that the state of charge is displayed in a stable linear relationship instead of a sudden change. For example, the second preset threshold can be set to 1%, that is, during the charging or discharging process of the electronic device, the absolute value of the difference between the two adjacent cycles of the displayed state of charge is allowed to have an error of only 1%.

As mentioned above, the first state of charge is only the cumulative power parameter value of each working module that can be obtained. When there is a communication abnormality, it is necessary to obtain the cumulative power parameter values that have been recently obtained in sequence by the working modules with the communication abnormality, and then correct the first state of charge before displaying it. Of course, it can also be corrected by other correction methods to make the final displayed state of charge have higher accuracy. Therefore, by comparing the first state of charge directly obtained with the displayed state of charge of the previous cycle, it can also be determined whether an abnormality has occurred. If the absolute value of the difference between the two is less than the second preset threshold, it can be determined that the communication is normal, so that the first state of charge can be directly displayed as the displayed state of charge without correcting it.

In one embodiment, when the absolute value of the difference between the first state of charge acquired in the current cycle and the displayed state of charge of the previous cycle is greater than a second preset threshold, the displayed state of charge of the current cycle is determined and displayed based on the displayed state of charge of the previous cycle and a preset adjustment value.

Specifically, after calculating the first state of charge of the current cycle, the main control module temporarily stores the first state of charge in the memory for calculation and comparison in the next cycle, and determines and displays the displayed state of charge of the current cycle according to the preset adjustment value and the displayed state of charge of the previous cycle.

In one embodiment, the electronic device control method provided by the present application further includes: obtaining the sampled current value of each working module in each preset cycle. Calculating the second state of charge of the device according to each sampled current value and the initial power parameter value. When the absolute value of the difference between the first state of charge and the second state of charge is less than a preset threshold, determining and displaying the display state of charge of the device according to the first state of charge and the second state of charge.

In this embodiment, the sampled current value of the working module refers to the current value obtained by the working module sampling its own current. In each preset cycle, the main control module establishes communication with each working module, and then obtains the sampled current value of each working module. Then the main control module can calculate the accumulated power parameter value of each working module according to each sampled current value, and then calculate the second state of charge of the device in combination with the initial power parameter value of the battery module.

It should be noted that the cumulative power parameter value of the working module used to calculate the first state of charge is calculated independently by each working module. The cumulative power parameter value of the working module used to calculate the second state of charge is calculated by the main control module based on the sampled current values of each working module.

If the absolute value of the difference between the first state of charge and the second state of charge is less than the preset threshold, it means that both can be used to reflect the state of charge of the device at the current moment. Therefore, in order to improve the rationality of the state of charge displayed by the device, the first state of charge and the second state of charge are combined to determine the state of charge that the device should display at the current moment (i.e., the displayed state of charge of the current cycle). For example, the first state of charge and the second state of charge are weighted averaged to obtain the power to be displayed.

In one embodiment, the main control module calculates the second state of charge of the device according to the following formula:

Among them, _FB represents the total power value of n working modules calculated by the main control module according to the sampled current values _I'n of n working modules, that is, the main control module first obtains the current value of each working module, and obtains the total power value of n working modules through ampere-hour integration according to the sum of the current values of each working module. t represents the current moment, _I'n represents the sampled current value of the nth working module in the time period of 0 to t (the time period of 0 to t may include one or more preset cycles, and the moment "0" may represent the power-on moment of the device), SOC _B represents the second state of charge, _F0 represents the charge capacity value corresponding to the initial power parameter value of the battery module, and F represents the total charge capacity value of the device.
