The driving range of new energy vehicles is affected by many factors, such as vehicle weight, battery capacity, driving style, and the power consumption of onboard electrical appliances. Specifically, the power consumption of onboard electrical appliances refers to the electrical components responsible for the vehicle's electrical functions, such as in-car refrigerators, navigation systems, and heaters. Since the power consumption of onboard electrical appliances is a significant factor affecting driving range, real-time monitoring and control of their power consumption is crucial for improving the driving range of new energy vehicles.

[0044] Figure 5 This is a schematic diagram of the structure of an electronic device for monitoring the power consumption of electrical appliances, provided in an embodiment of this application. Detailed Implementation

[0045] As described above, current power consumption monitoring technologies for automotive electrical appliances typically use MOS devices to detect the current flowing through the appliance to determine its power consumption. While this method can monitor the power consumption of each automotive electrical appliance, it requires a separate MOS device for each appliance, and each new appliance requires an additional MOS device for power consumption monitoring, resulting in low power consumption monitoring efficiency.

[0046] To address the aforementioned problems, this application provides a method and related equipment for monitoring the power consumption of electrical appliances. In the real-time power consumption monitoring method provided in this application, the power consumption types of multiple vehicle-mounted electrical appliances are first classified to obtain the power consumption categories corresponding to each appliance. These categories include dynamic appliances and steady-state appliances. A steady-state appliance is one whose power consumption variation is less than a preset threshold under preset operating conditions; a dynamic appliance is one whose power consumption variation is not less than the preset threshold under the preset operating conditions. Then, for a first vehicle-mounted appliance among the multiple appliances, a preset power consumption calculation strategy is determined based on its power consumption category. This preset power consumption calculation strategy represents the power consumption influence factor of the appliance and the power consumption calculation formula based on the influence factor. Finally, the first current power consumption of each of the multiple appliances is determined according to its corresponding preset power consumption calculation strategy. In the above method, a preset power consumption calculation strategy can be determined based on the specific power consumption category of the vehicle's in-vehicle electrical appliances. This preset power consumption calculation strategy reveals the power consumption influence factors of the in-vehicle electrical appliances and the power consumption calculation formula based on these factors. Finally, the first current power consumption of the in-vehicle electrical appliances can be determined based on this preset power consumption calculation strategy. When it is necessary to calculate the current power consumption of an in-vehicle electrical appliance, the current power consumption can be determined by the power consumption influence factors related to that appliance and the corresponding power consumption calculation formula, eliminating the need to obtain the power consumption of the appliance by allocating MOS devices, thus improving the efficiency of power consumption monitoring.

[0047] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0048] See Figure 1 The figure is a flowchart illustrating a method for monitoring the power consumption of electrical appliances according to an embodiment of this application, specifically including the following steps:

[0049] S101: The power consumption types of the plurality of vehicle-mounted electrical appliances are classified to obtain the power consumption categories corresponding to each of the plurality of vehicle-mounted electrical appliances; the power consumption categories include: dynamic electrical appliances and steady-state electrical appliances; the steady-state electrical appliances are electrical appliances whose power change amplitude is less than a preset threshold under preset operating conditions; the dynamic electrical appliances are electrical appliances whose power change amplitude is not less than the preset threshold under the preset operating conditions.

[0050] The power consumption monitoring method for electrical appliances provided in this application is applicable to vehicles that include multiple in-vehicle electrical appliances. Before monitoring the power consumption of in-vehicle electrical appliances, it is necessary to classify the power consumption type of each in-vehicle electrical appliance to obtain the power consumption category corresponding to each appliance individually.

[0051] The power consumption of in-vehicle electrical appliances can be broadly categorized into two types: dynamic electrical appliances and steady-state electrical appliances. Steady-state electrical appliances are those whose power consumption variation is less than a preset threshold under preset operating conditions. These preset operating conditions refer to the pre-defined operating environment provided for the in-vehicle electrical appliances. The operating environment can include various factors such as temperature, humidity, vehicle vibration, electromagnetic interference, and power supply stability. Classifying the power consumption type of electrical appliances by setting uniform preset operating conditions allows for a better understanding of power consumption changes under extreme or relatively harsh environments, and the power consumption category can be defined based on the amplitude of the power consumption variation under these conditions. Steady-state electrical appliances, whose power consumption is less than the preset threshold under preset operating conditions, tend to have relatively stable power consumption and are not easily affected by the environment. Examples include vehicle body electrical appliances, door lock controllers, and infotainment appliances.

[0052] Correspondingly, dynamic electrical appliances are those whose power variation exceeds a preset threshold under preset operating conditions. Dynamic electrical appliances are often more susceptible to external environmental factors such as temperature, vehicle speed, and motor output power, or internal operating conditions. Therefore, the influencing factors for different dynamic electrical appliances often differ. Common dynamic electrical appliances include power controllers, motor and battery cooling controllers, and air conditioning controllers. Dynamic electrical appliances are more easily affected by external environmental factors such as the operating environment. Therefore, in the subsequent calculation of the power consumption of dynamic electrical appliances, it is necessary to determine their power consumption based on the specific power consumption influencing factors of the dynamic electrical appliance.

[0053] S102: For the first vehicle electrical appliance among the plurality of vehicle electrical appliances, a preset power consumption calculation strategy for the first vehicle electrical appliance is determined based on the power consumption category of the first vehicle electrical appliance; the preset power consumption calculation strategy is used to represent the power consumption influence factor of the vehicle electrical appliance and the power consumption calculation relationship based on the power consumption influence factor.

[0054] After classifying the power consumption categories of in-vehicle electrical appliances, a preset power consumption calculation strategy is determined for each specific category. This preset power consumption calculation strategy represents the power consumption influence factors that affect the power consumption of in-vehicle electrical appliances, as well as the power consumption calculation formula based on these factors.

[0055] As mentioned above, the power consumption of dynamic electrical appliances is often more susceptible to external environmental factors, and the influencing factors differ for different dynamic electrical appliances. Although the power consumption of static electrical appliances is less affected by external factors, its specific power consumption is still determined by the appliance's own operating mode. Therefore, in this application, the preset power consumption calculation strategies differ for electrical appliances of different power consumption categories. Next, taking the first vehicle-mounted electrical appliance as an example, we will explain in detail the process of determining its preset power consumption calculation strategy based on its power consumption category. When the first vehicle-mounted electrical appliance is a dynamic electrical appliance, the process of determining its preset power consumption calculation strategy specifically includes the following two steps:

[0056] Step 1: If the power consumption category of the first vehicle electrical appliance is the dynamic type electrical appliance, then obtain the electrical function type of the first vehicle electrical appliance; the electrical function type includes at least one of the following: braking function, steering function, and cooling function;

[0057] Step 2: Based on the electrical function type of the first vehicle-mounted electrical appliance, determine the preset power consumption calculation strategy for the first vehicle-mounted electrical appliance.

[0058] When the power consumption category of the first vehicle-mounted electrical appliance is determined to be a dynamic electrical appliance, the electrical function type of the first vehicle-mounted electrical appliance will be further obtained, and the corresponding preset power consumption calculation strategy will be determined based on the electrical function type of the first vehicle-mounted electrical appliance.

[0059] The power consumption influencing factors differ for different dynamic electrical appliances. Therefore, this application uses the electrical function of the dynamic electrical appliance as the basis for determining the corresponding preset power consumption calculation strategy. Specifically, electrical function types include braking, steering, and cooling functions. Mapping these electrical function types to specific power-type electrical appliances, the dynamic electrical appliances can include: a power controller, a motor and battery cooling water pump, a steering controller, an air conditioning compressor, and a cooling fan, etc. Different dynamic electrical appliances have different power consumption influencing factors. For example, the power consumption influencing factor of the power controller is the dynamic power consumption of torque output; the power consumption influencing factors of the motor and battery cooling water pump are the motor and battery water temperature, motor opening degree, and motor rated power; the power consumption influencing factors of the steering controller are the current vehicle driving mode, steering angle, steering rate, and steering motor output power; the power consumption influencing factor of the air conditioning compressor is the cooling / heating setting; and the power consumption influencing factor of the cooling fan is the air conditioning request pressure, vehicle speed, and cooling fan rated power.

[0060] Among the power consumption influencing factors corresponding to the various dynamic controllers mentioned above, each power consumption influencing factor can constitute the power consumption calculation formula in its preset power consumption calculation strategy. The power consumption calculation formulas formed by different power consumption influencing factors are different. Taking a cooling fan as an example, its corresponding power consumption influencing factors are the air conditioning requested pressure, vehicle speed, and the rated power of the cooling fan. The power consumption calculation formula for the cooling fan is as follows:

[0061] P 风扇 =α*P 额定 ;

[0062] In the formula, P 风扇 P represents the power consumption of the cooling fan, α represents the opening degree of the cooling fan, and P represents the operating power of the cooling fan. 额定 This indicates the rated power of the cooling fan. The relationship between the cooling fan opening degree and the requested air conditioning pressure and vehicle speed is shown in the table below:

[0063]

[0064] The left and top rows of the table represent different vehicle speeds and different air conditioning demand pressures, respectively. The percentage data in the table represents the cooling fan opening value under different air conditioning demand pressures and vehicle speeds. When calculating the cooling fan's power consumption, the fan opening at a specific air conditioning demand pressure and vehicle speed can be determined by looking up the table, and the cooling fan's power consumption can be determined based on the fan opening and the fan's rated power.

[0065] Taking a motor-cooled water pump as an example again, the power consumption factors of a motor-cooled water pump are motor temperature, motor opening degree, and motor rated power. The power consumption calculation formula for a motor-cooled water pump is as follows:

[0066]

[0067] In the formula, P 电机 This indicates the power consumption of the motor. P indicates the motor's opening degree. 额定 This indicates the motor's rated power. Similarly, the motor's operating degree can be determined by pre-stored relationships between motor operating degree and water temperature, thereby calculating the motor's power consumption. The relationship between motor operating degree and water temperature is shown in the following diagram. Figure 2 As shown, based on Figure 2 The disclosed schematic diagram of the relationship between motor opening degree and water temperature can determine the motor opening degree at different water temperatures, thereby calculating the current power consumption of the motor.

[0068] When the power consumption category of the first on-board electrical appliance is a steady-state appliance, the process of determining the preset power consumption calculation strategy includes the following two steps:

[0069] Step 1: If the power consumption category of the first vehicle-mounted electrical appliance is the steady-state type electrical appliance, then obtain the current working mode of the first vehicle-mounted electrical appliance;

[0070] Step 2: Based on the current operating mode of the first vehicle-mounted electrical appliance, determine the preset power consumption calculation strategy for the first vehicle-mounted electrical appliance.

[0071] Steady-state electrical appliances typically operate with relatively stable performance and are not easily affected by changes in external environmental factors. Therefore, when the power consumption category of the first on-board electrical appliance is steady-state, its power consumption can be directly determined based on the appliance's supply voltage and operating current. However, the supply voltage and operating current differ depending on the operating mode of the steady-state appliance. Therefore, when the first on-board electrical appliance is steady-state, its operating mode is selected, and then the corresponding preset power consumption calculation strategy can be determined based on the appliance's operating mode. The preset power consumption calculation strategy for steady-state appliances includes the operating current and supply voltage of the appliance under different operating modes. By calculating the power of the steady-state appliance, the current power consumption of that appliance can be obtained.

[0072] S103: Determine the first current power consumption of the multiple vehicle electrical appliances according to their respective preset power consumption calculation strategies.

[0073] After obtaining the preset power consumption calculation strategy corresponding to each vehicle electrical appliance, the first current power consumption of multiple vehicle electrical appliances can be determined based on the power consumption influence factor in the calculation strategy and the power consumption calculation relationship formed by the power consumption influence factor, thereby completing the power consumption monitoring of each electrical appliance in the vehicle.

[0074] As an optional implementation, the following step is included before step S101:

[0075] Step 1: Obtain the first total power consumption of the vehicle; the first total power consumption is the sum of the power consumption of all high-voltage electrical appliances and pre-specified low-voltage electrical appliances in the vehicle.

[0076] Before classifying the power consumption types of in-vehicle electrical appliances, we can first obtain the vehicle's initial total power consumption value. This initial total power consumption value represents the sum of the power consumption of all high-voltage electrical appliances and pre-specified low-voltage electrical appliances in the vehicle.

[0077] In vehicle electrical systems, high-voltage electrical appliances refer to those operating at voltages higher than 200V-400V, such as drive motors, generators, and frequency converters. High-voltage appliances often account for a significant portion of a vehicle's electrical energy consumption, and their power consumption varies with the vehicle's driving mode. Low-voltage electrical appliances, on the other hand, operate at voltages below 60V, such as headlights, dashboards, and seat heaters. Because some low-voltage appliances in a vehicle have excessively low voltages, their power consumption cannot be accurately measured. Therefore, the first total power consumption value is the sum of the power consumption of all high-voltage appliances and a subset of pre-specified low-voltage appliances. This first total power consumption value can be used to improve the accuracy of subsequent calculations of appliance power consumption. This first total power consumption value can be obtained using a current sensor. Due to the large proportion of power consumption by high-voltage appliances, using a current sensor to detect the current accurately yields the first total power consumption value comprised of both high-voltage and low-voltage appliances.

[0078] As another optional implementation, after step S103, the following three steps are also included:

[0079] Step 1: Based on the first current power consumption of the plurality of vehicle electrical appliances, calculate the sum of the first current power consumption values ​​of the plurality of vehicle electrical appliances to obtain the second total power consumption value;

[0080] Step 2: Determine the power consumption correction coefficient based on the first total power consumption value and the second total power consumption value;

[0081] Step 3: Correct the first current power consumption of the plurality of vehicle electrical appliances using the power consumption correction coefficient to obtain the second current power consumption of the plurality of vehicle electrical appliances; the second current power consumption represents the power consumption obtained after correcting the first current power consumption.

[0082] As described above, the initial total power consumption of the vehicle obtained before classifying the power consumption of in-vehicle electrical appliances can be used to improve the accuracy of subsequent calculations of appliance power consumption. However, optimizing the current power consumption data of the electrical appliances requires a power consumption correction coefficient.

[0083] In determining the power consumption correction factor, the sum of the power consumption values ​​of all in-vehicle electrical devices is first calculated based on the current power consumption of multiple in-vehicle electrical devices; this sum is the second total power consumption value. Then, the power consumption correction factor is determined based on the previously obtained first and second total power consumption values. The specific formula for calculating the power consumption correction factor is shown below:

[0084] k = (Pz - Pd - Pw) / (Pd + Pw)

[0085] In the formula, k represents the power consumption correction coefficient; Pz represents the first total power consumption value obtained before calculating the current power consumption; Pd represents the total power consumption of dynamic electrical appliances; Pw represents the total power consumption of steady-state electrical appliances; Pd+Pw is the total power consumption of all vehicle electrical appliances.

[0086] The power consumption correction coefficient can be calculated using the above formula. Based on the power consumption correction coefficient, the first current power consumption of the vehicle electrical appliances can be corrected to make its value closer to the actual power consumption value, thereby ensuring the accuracy of power consumption monitoring of the vehicle electrical appliances and obtaining the second current power consumption.

[0087] For details, please refer to Figure 3 The following scheme is further understood by illustrating a schematic diagram of a power consumption display instrument panel.

[0088] As another optional implementation, after step S103, the following three steps are also included:

[0089] Step 1: Obtain the multiple electrical function types of the multiple vehicle-mounted electrical appliances;

[0090] Step 2: Based on the multiple electrical function types, classify and sum the second current power consumption of the multiple vehicle electrical appliances to obtain the third current power consumption corresponding to each of the multiple electrical function types; the third current power consumption is the sum of the second current power consumption of the vehicle electrical appliances belonging to the same electrical function type;

[0091] Step 3: Based on the multiple electrical function types, display the third current power consumption corresponding to each of the multiple electrical function types.

[0092] After calculating the power consumption of each in-vehicle electrical appliance to obtain its initial current power consumption, its specific power consumption needs to be displayed. Since vehicles often have a large number of sophisticated electrical functions, even appliances of the same electrical type may have multiple different appliances. Therefore, when displaying the power consumption of various in-vehicle electrical appliances, showing both the electrical function and its corresponding multiple appliances provides a more intuitive view of the specific power consumption under different electrical functions within the vehicle.

[0093] Therefore, by acquiring the electrical function types corresponding to each of the multiple in-vehicle electrical appliances, and classifying and summing them based on their respective electrical function types, the overall power consumption for different electrical function types can be obtained, namely the third current power consumption. Finally, the third current power consumption is displayed on the instrument panel, which can accurately show the user the specific power consumption of different electrical function types of the vehicle, as well as the specific power consumption of different motors under a single electrical function type. This allows the driver to adjust the working mode of each electrical appliance according to their own needs, thereby ensuring the driver's driving experience.

[0094] This embodiment provides a method for monitoring the power consumption of electrical appliances. In the real-time power consumption monitoring method provided in this application, the power consumption types of multiple vehicle-mounted electrical appliances are first classified to obtain the power consumption categories corresponding to each of the multiple vehicle-mounted electrical appliances. The power consumption categories include: dynamic electrical appliances and steady-state electrical appliances; the steady-state electrical appliance is an appliance whose power change amplitude under preset operating conditions is less than a preset threshold; the dynamic electrical appliance is an appliance whose power change amplitude under the preset operating conditions is not less than the preset threshold. Then, for a first vehicle-mounted electrical appliance among the multiple vehicle-mounted electrical appliances, a preset power consumption calculation strategy for the first vehicle-mounted electrical appliance is determined based on its power consumption category; the preset power consumption calculation strategy is used to represent the power consumption influence factor of the vehicle-mounted electrical appliance and the power consumption calculation formula based on the power consumption influence factor. Finally, according to the preset power consumption calculation strategies corresponding to each of the multiple vehicle-mounted electrical appliances, the first current power consumption of the multiple vehicle-mounted electrical appliances is determined. In the above method, a preset power consumption calculation strategy can be determined based on the specific power consumption category of the vehicle's in-vehicle electrical appliances. This preset power consumption calculation strategy reveals the power consumption influence factors of the in-vehicle electrical appliances and the power consumption calculation formula based on these factors. Finally, the first current power consumption of the in-vehicle electrical appliances can be determined based on this preset power consumption calculation strategy. When it is necessary to calculate the current power consumption of an in-vehicle electrical appliance, the current power consumption can be determined by the power consumption influence factors related to that appliance and the corresponding power consumption calculation formula, eliminating the need to obtain the power consumption of the appliance by allocating MOS devices, thus improving the efficiency of power consumption monitoring.
