[0040] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other. The steps shown in the flowcharts can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowcharts, in some cases, the steps shown or described may be performed in a different order than that shown here.

[0041] The technical solution of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] Figure 1 This is a flowchart illustrating the control method for the electronic device in this application. Figure 1 ,like Figure 1 As shown, it includes:

[0043] Step 101: Determine the internal temperature parameters of the battery based on the battery status information of the electronic device;

[0044] Here, the battery's state information includes, but is not limited to, the battery's surface temperature parameters, battery impedance parameters, and current parameters. By detecting the battery's state information, the electronic device can obtain at least the battery's surface temperature parameters, battery impedance parameters, and / or current parameters. Based on these parameters, a prediction model can be established, and the battery's current internal temperature can be predicted to determine its internal temperature parameters.

[0045] Here, during the battery manufacturing process, internal temperature parameters are detected by placing a temperature sensor inside the battery, while external temperature sensors detect surface temperature, impedance, and current parameters. Based on the relationship between these internal and external temperature parameters, a predictive model is established to predict the battery's internal temperature parameters. This model can be: Tcore = f(Tsurface, R, Ipeak, t); where Tcore represents the battery's internal temperature parameter, Tsurface represents the battery's surface temperature parameter, R represents the cell impedance, Ipeak represents the peak current parameter, and t represents time. This predictive model allows for the prediction of the battery's internal temperature parameters during post-manufacturing use, thereby protecting the battery and ensuring the electronic equipment operates at high performance.

[0046] Step 102: Determine the peak current parameters that the battery can support within a preset temperature range based on the internal temperature parameters.

[0047] Here, the preset temperature can be a range value. The electronic device determines the first usage time of the battery. Based on the internal temperature parameter, the first peak current parameter of the battery corresponding to the first usage time within the preset temperature can be determined. The first peak current parameter is used by the electronic device to adjust power consumption.

[0048] In one implementation, the electronic device can compare the internal temperature parameter with a preset value of the preset temperature; if the comparison result indicates that the internal temperature parameter is less than the preset value, a first peak current parameter of the battery corresponding to the first usage time within the preset temperature is determined.

[0049] Here, the preset value can be the upper limit of the preset temperature or any value of the preset temperature, which can be set according to actual needs.

[0050] Here, the preset temperature can also be a specific value. When the electronic device determines the first usage time of the battery, it can compare the internal temperature parameter of the battery with the temperature value corresponding to the preset temperature. If the comparison result indicates that the internal temperature parameter is less than the temperature value corresponding to the preset temperature, then the first peak current parameter of the battery corresponding to the first usage time within the preset temperature is determined.

[0051] Here, if the temperature difference between the internal temperature parameter and the preset value is less than a first threshold, the first peak current parameter is less than or equal to the current parameter; if the temperature difference between the internal temperature parameter and the preset value is greater than or equal to the first threshold, the first peak current parameter is greater than the current parameter.

[0052] For example, if the predicted internal temperature of the battery is 65 degrees Celsius, the surface temperature is 25 degrees Celsius, and the preset temperature is 70 degrees Celsius, by comparing 65 and 70, it is determined that the internal temperature is lower than the preset temperature, and the temperature difference between the internal temperature and the preset temperature is less than a first threshold of 10. In this case, the supported first peak current parameter must be lower than the current parameter. For example, if the original current parameter was 10 amps, the supported first peak current parameter could now be 5 amps. This can represent the predicted first usage time of the battery in the future, such as 10 minutes. If discharged at a current intensity of 2 amps, it can discharge for 10 minutes; if discharged at a current intensity of 5 amps, it can discharge for 5 minutes.

[0053] Here, if the internal temperature parameter of the battery is compared with a preset value of a preset temperature, and the comparison result indicates that the internal temperature parameter is greater than or equal to the preset value, and the temperature difference between the internal temperature parameter and the preset value is less than a second threshold, then the electronic device is controlled to output a high temperature alarm signal; or, if the comparison result indicates that the internal temperature parameter is greater than or equal to the preset value, and the temperature difference between the internal temperature parameter and the preset value is greater than the second threshold, then the electronic device is controlled to perform a shutdown operation.

[0054] Here, the electronic device can also dynamically adjust the preset temperature based on the current battery status information (such as charging and discharging current value). For example, when the current is low, the preset temperature can be 40 degrees Celsius, and when the current is high, the preset temperature can be 30 degrees Celsius to ensure battery safety.

[0055] Step 103: Control the power consumption adjustment of the electronic device based on the peak current parameter.

[0056] Here, the electronic device can detect the current voltage of the battery to obtain the current voltage parameters of the battery, determine the peak discharge power parameters currently supported by the battery based on the voltage parameters and the peak current parameters of the current battery, and control the electronic device to adjust the power consumption based on the peak discharge power parameters.

[0057] The peak discharge power parameter is Ppeak (=Ipeak*V), where Ipeak represents the peak current parameter and V represents the voltage parameter.

[0058] In this application, when an electronic device obtains the current peak discharge power parameter of the battery, it can send the peak discharge power parameter to the control unit of the electronic device, so that the control unit controls the electronic device to adjust the power consumption based on the peak discharge power parameter.

[0059] Here, the control unit of the electronic device can be an embedded controller (EC). The electronic device can obtain the usage parameters of its central processing unit (CPU) and graphics processing unit (GPU), compare the CPU and GPU usage parameters with preset values ​​respectively, and reduce the CPU's power consumption through the EC if the CPU's usage parameters are greater than or equal to the preset value, and reduce the GPU's power consumption through the EC if the GPU's usage parameters are greater than or equal to the preset value. Power consumption adjustment of the electronic device is not limited to the CPU and GPU; it can also include components with power consumption requirements such as memory, SSD, and fans. During power consumption adjustment, the current scenario of the electronic device can be obtained to ensure the power consumption requirements of high-priority components are met while reducing the power consumption of components with high power consumption requirements. For example, in a game scenario, the GPU consumes more power and has a higher priority, so the power consumption of other components is reduced, thereby ensuring the overall power consumption adjustment of the electronic device.

[0060] Here, the electronic device can reduce power consumption by shutting down unused applications, processes, or threads within a preset time period.

[0061] Here, when the peak discharge power parameter is greater than or equal to the preset parameter, the power consumption of the CPU and GPU can be reduced simultaneously; when the peak discharge power parameter is less than the preset parameter, the power consumption of the corresponding components can be adjusted according to the comparison results of the GPU and CPU with the preset values.

[0062] In this application, when the electronic device sends the peak discharge power parameter to the control unit, it can send it to the control unit of the electronic device in real time, or it can send the peak discharge power parameter to the control unit of the electronic device at preset intervals.

[0063] The control method for electronic devices provided in this application determines the internal temperature parameters of the battery by detecting the battery's state information, determines the peak current parameters that the battery can support within a preset temperature based on the internal temperature parameters, and controls the electronic device to adjust power consumption based on the peak current parameters. This is a scheme that presets the internal temperature of the battery based on the battery state information, calculates the maximum current that the battery can support within the preset temperature based on the relationship between the internal temperature of the battery and the peak current, and ensures that the battery always operates under safe temperature conditions, thereby maximizing the peak performance of the electronic device.

[0064] Figure 2 This is a flowchart illustrating the control method for the electronic device in this application. Figure 2 ,like Figure 2 As shown, the method includes:

[0065] Step 201: Real-time detection of battery surface temperature parameters, cell impedance parameters, and peak current parameters;

[0066] Here, electronic devices can establish a predictive model for predicting the internal temperature of a battery based on the relationship between the battery's surface temperature parameters, cell impedance parameters, peak current parameters, and internal temperature parameters.

[0067] Step 202: Predict the internal temperature parameters of the battery within the next t seconds under the current peak current parameters based on the prediction model.

[0068] Here, the internal temperature parameter Tcore = f(Tsurface,R,Ipeak,t);

[0069] Step 203: Set the preset temperature corresponding to the battery's internal temperature based on the battery's current state information;

[0070] Here, the internal temperature of the battery, Tcore, is lower than the corresponding preset temperature, T0.

[0071] Step 204: Calculate in real time the peak discharge current that the battery can support within the preset temperature range in the next t seconds;

[0072] Here, the peak discharge current Ipeak = g(Tcore,R,t);

[0073] Step 205: Calculate the maximum supported discharge power based on the peak discharge current and report it to the current system of the electronic device every t seconds in real time;

[0074] Here, the maximum discharge power Ppeak = Ipeak * V.

[0075] Step 206: The system dynamically adjusts the power limit of the electronic device according to the received maximum discharge power, so that the system power consumption is always less than or equal to the maximum discharge power.

[0076] Here, electronic devices dynamically adjust system power consumption by receiving the maximum peak discharge power that the battery can support in real time. This allows electronic devices to achieve maximum performance while ensuring the safety of the battery's internal temperature, guaranteeing battery safety and system stability, and preventing safety risks caused by excessive battery temperature and power failures that lead to shutdowns.
