Description

[Technical Field]

[0001] The present invention relates to the technical field of motors, and in particular to the calculation of carbon emissions of moving vehicles. [Background technology]

[0002] Currently, carbon emissions from electric vehicles are estimated primarily based on the electrical energy consumed by the battery during operation. There are two common methods for measuring battery power. The first is to directly measure the battery unit's voltage externally. The second is to measure the voltage using a battery management system built into the battery unit. However, if the load suddenly increases (if the output current increases), the battery voltage drops, potentially leading to an inaccurate determination of remaining battery capacity based solely on voltage. Furthermore, after a battery is used for a certain period of time, repeated charging and discharging can cause the battery cells to deteriorate, increasing their internal resistance and potentially leading to an inaccurate determination of remaining battery capacity. To address the aforementioned battery cell degradation issue, lithium-iron batteries, which can be charged and discharged more frequently, are now being used. However, due to the characteristics of lithium-iron batteries, the voltage change during the charging and discharging process is small, making it difficult to accurately estimate the remaining battery capacity.

[0003] In other words, if the remaining battery capacity is estimated incorrectly, the amount of power used by the battery will also be estimated incorrectly, and the carbon emissions of each trip of the electric vehicle will also be estimated incorrectly. In addition, conventional carbon emission calculation methods are limited by issues such as transmission bandwidth, speed, and server capacity, and only the distance traveled by the electric vehicle and the remaining battery capacity at the start and end of each trip can be used as the basis for calculating the carbon emissions of the trip, leaving room for fraud. As a result, it is not possible to truly accurately calculate carbon emissions. Therefore, how to solve the above problem is an objective of the present invention. Summary of the Invention [Problem to be solved by the invention]

[0004] The present invention aims to provide a method for calculating carbon emissions based on the power energy consumption of the motor of a mobile vehicle, which uses high-frequency measurement, edge computing, and cumulative calculation technologies to significantly improve the accuracy of calculating carbon emissions for each trip, thereby enabling everyone to make effective use of environmentally friendly mobile vehicles, enabling the efficient trading of carbon credits, and creating a sharing economy in the carbon credit market.

[0005] Another object of the present invention is to provide a method for calculating carbon emissions based on the power consumption energy of a motor in a mobile vehicle, which can verify the actual usage status of the motor by using high-frequency measurement to confirm whether the motor current and voltage input by the control module correspond to the fluctuations in position information, thereby reducing the fraud of carbon emissions and ensuring fair trading of carbon credits, thereby ensuring the reduction of greenhouse gases.

[0006] Another object of the present invention is to provide a method for calculating carbon emissions based on the power energy consumption of a motor in a moving vehicle, which can use edge computing technology to reduce the bandwidth load when uploading to the cloud and improve the upload speed, thereby further reducing the load of calculation, data storage, and data processing on the cloud server. [Means for solving the problem]

[0007] The method for calculating carbon emissions based on the power consumption energy of a motor in a mobile vehicle of the present invention can be used in a control module that operates and controls a battery unit in a mobile vehicle and drives the motor, and the control module at least includes a central processing unit, a storage unit connected to the central processing unit, a motor control unit that operates and controls the motor, at least one sensor unit that detects the voltage and current of the battery unit, a timer unit, a GPS module that is connected to at least one external positioning satellite system, and a communication unit that transmits data to at least one external cloud server, wherein the storage unit further includes an accumulation calculation unit and a data collection and analysis unit.

[0009] As shown in FIG. 1, the present invention is applied to a control module 100 for controlling a motor 50 and a battery unit 60 in a mobile vehicle. The control module 100 includes a motor control panel 10 and a communication control panel 20. The motor control panel 10 includes a central processing unit 11, a memory unit 12 connected to the central processing unit 11, a motor control unit 15, at least one sensor unit 16, and a first transmission unit 18. The central processing unit 11 executes and processes programs, data, and commands. The memory unit 12 stores programs, power consumption (hereinafter referred to as "energy consumption") calculation formulas, measurement information, and cumulative calculation results. The memory unit 12 also includes an accumulation calculation unit 14 that can accumulate multiple energy consumption calculation results during the same trip. The motor control unit 15 is connected to an external motor 50 to control the operation of the motor 50. Furthermore, the plurality of sensor units 16 can be connected to an external battery unit 60 for supplying power to the control module 100, thereby measuring the current and voltage input from the battery unit 60 when the control module 100 drives the motor 50. The timer unit 17 can set and operate the plurality of sensor units 16 to measure the voltage and current input from the battery unit 60, thereby calculating the cycle of power consumption. The first transmission unit 18 is used to transmit data between the motor control panel 10 and the communication control panel 20. According to various embodiments, the central processing unit 11, the memory unit 12, the motor control unit 15, the timer unit 17, and / or the first transmission unit 18 can be integrated semiconductor devices.

[0010] 1, 3 and 4, when the present invention is actually used, the control module 100 can perform high-frequency measurements while the vehicle is traveling, and edge computing technology is used to calculate the power consumption energy when the battery unit 60 drives the motor 50. The total power consumption energy generated during the traveling is accumulated, and the carbon emissions for the traveling converted from the power consumption energy for the traveling are uploaded, allowing for carbon credit trading. Before using the present invention, the operation control of each item in the program executed by the central processing unit 11 in the motor control panel 10 of the control module 100 and the processing core unit 21 in the communication control panel 20 can be set in advance. The settings include at least a trigger condition (the time for the instantaneous voltage value when the battery unit 60 supplies power to the control module 100 at startup, e.g., 0.1 seconds), a measurement period setting (e.g., measuring once when the rotation angle of the output shaft reaches 10 degrees), a position information reading period setting (the time interval for reading the position and distance, e.g., reading once every 10 seconds), and an upload time setting (the time interval for uploading data, e.g., uploading once every 60 seconds). The process of the method for calculating carbon emissions based on the power consumption energy of the motor in a mobile vehicle of the present invention is as follows.

[0011] In process (a) of turning on the power of a mobile vehicle and starting it to run, when the mobile vehicle starts preparing to run a trip, the mobile vehicle is first powered on, and then data related to the start of running of the mobile vehicle stored in the motor control panel 10 and the memory unit 12 and storage unit 22 of the communication control panel 20 is transmitted to the cloud via the communication unit 27 of the communication control panel 20. The data includes, but is not limited to, accumulated power consumption energy, location information, etc. Furthermore, after the user externally starts the motor 50 and waits for the mobile vehicle to start running, process (b) is executed.

[0012] In process (b) of initiating calculation of driving power consumption energy, when a user turns on the power supply of the mobile vehicle and externally starts the motor 50 to drive the mobile vehicle via the output shaft, the motor 50 is driven by the input current of the battery unit 60 via the control module 100. As soon as the sensor units 16 of the motor control panel 10 detect that the duration of an instantaneous voltage rise when the battery unit 60 supplies power to drive the motor 50 reaches the set value (0.1 seconds) of the timer unit 17, execution of process (c) is initiated internally. The central processing unit 11 of the motor control panel 10 calculates the externally started power consumption energy of the motor 50 using the power consumption energy program stored in the memory unit 12. The externally started power consumption energy is defined as the starting power consumption energy and is temporarily stored in the memory unit 12.

[0013] In process (c) of acquiring unit period measurement parameters during running at a set period, when the mobile vehicle is started and driven, the communication control panel 20 of the control module 100 uses the GPS module 24 to read the position information of the mobile vehicle based on the period (e.g., every 10 seconds) set by the timer unit 23, and temporarily stores the position information of each unit period in the storage unit 22. Furthermore, the plurality of sensor units 16 of the motor control panel 10 measure the current and voltage parameters of the control module 100 input from the battery unit 60 based on the period (e.g., every 0.1 seconds) set by the timer unit 17, and temporarily stores the current and voltage parameters of each unit period in the buffer area of ​​the memory unit 12. Then, process (d) is executed.

[0014] In the process (d) of calculating the unit power consumption energy per unit period, after the unit period measurement parameters are obtained, the power consumption energy program in the central processing unit 11 of the motor control panel 10 calculates the unit power consumption energy of the motor 50 for each unit period based on the above-mentioned current and voltage parameters, and temporarily stores each unit power consumption energy in the memory unit 12 one by one. Then, the process (e) is executed.

[0015] In process (e) of accumulating the unit power consumption energy during driving, generating the accumulated power consumption energy, and uploading it to the cloud, once the calculation of a plurality of unit power consumption energies is completed, the calculations that have already been completed are accumulated according to the upload time setting and conditions, for example, once every 60 seconds, and the unit power consumption energies that have not yet been accumulated are generated as accumulated power consumption energies, and the accumulated power consumption energy and location information in the memory unit 12 and storage unit 22 are uploaded to the specified cloud server 80 via the communication unit 27 of the communication control panel 20. At the same time, once the upload is completed, the location information that has already been uploaded in the storage unit 22 is cleared, and process (f) is executed.

[0016] In process (f), which determines whether a trigger to end the trip has been received, once the upload of each cumulative power consumption energy has been completed, the system determines whether a trigger to end the trip has been received. If the system has not received a trigger to end the trip, it loops through processes (c) to (e), and conversely, if a trigger to end the trip has been received, it executes process (g).

[0017] In process (g) of ending a trip, when the system receives a trip end trigger, for example, when the battery unit 60 of the mobile vehicle stops inputting current to the control module 100, the communication unit 27 of the communication control panel 20 uploads the final data stored in the memory unit 12 and storage unit 22 of the motor control panel 10 and the communication control panel 20 to the designated cloud server 80. The final data includes, but is not limited to, accumulated power consumption energy, location information, etc. At the same time, upon completion of the upload, the location information uploaded in the storage unit 22 is cleared and the trip is ended. Thereby, the designated cloud server 80 converts the starting power consumption energy, the accumulated power consumption energy, and the location information uploaded during the trip of the mobile vehicle into carbon emissions, and sums them to calculate the total carbon emissions for one trip, allowing for subsequent carbon credit trading.

[0018] For example, FIG. 5 is a flowchart illustrating the operation of a preferred embodiment of the method of the present invention. When the mobile vehicle starts moving, the mobile vehicle control module 100 transmits start data, such as the uncleared accumulated power consumption energy in the memory unit 12 and the current location information in the storage unit 22, to the designated cloud server 80. Furthermore, when triggering the start of the motor 50, it determines whether the time for the instantaneous voltage input from the battery unit 60 reaches a preset value. For example, if the preset value is not reached, it continues to wait for the trigger. Conversely, if the preset value is reached, it calculates the start-up power consumption energy and the unit power consumption energy per unit period using the measured instantaneous voltage and instantaneous current. Furthermore, it generates the accumulated power consumption energy by sequentially accumulating the unit power consumption energy, and it continues to determine whether the time for reading the location information has arrived. If the condition is not met, it continues to wait for the next unit period reading time. Conversely, if the unit period reading time arrives, it reads the location information and stores it in the storage unit 22, and it continues to determine whether the time for uploading the data to the cloud has arrived. If the upload time has not yet arrived, it repeatedly determines whether the time has come to measure the instantaneous voltage and instantaneous current and read the location information. Conversely, if the time has come to upload the data, it uploads the data to the cloud. The data includes, but is not limited to, accumulated power consumption energy, location information, etc. Furthermore, when the upload is complete, it clears the uploaded location information, and then it continues to determine whether the trip has ended. If the trip has not yet ended, it repeatedly determines whether the time has come to measure the instantaneous voltage and instantaneous current and read the location information and upload the data. Conversely, if the trip end is triggered, it uploads the final data to the cloud. The final data includes, but is not limited to, starting power consumption energy, accumulated power consumption energy, location information, etc. Furthermore, when the upload is complete, it clears the uploaded location information and ends the trip.

[0019] According to various embodiments, as shown in FIG. 2 , the control module 100 may comprise a motor control panel 30. The motor control panel 30 includes a central processing unit 31, a storage unit 32 connected to the central processing unit 31, a motor control unit 35, at least one sensor unit 36, a timer unit 37, a GPS module 38, and a communication unit 39. The central processing unit 31 executes and processes programs, data, and commands. The motor control unit 35 is connected to an external motor 50 to control and operate the motor 50. The sensor unit 36 ​​is connected to an external battery unit 60 to supply power to the control module 100, thereby measuring the current and voltage input when the battery unit 60 drives the motor 50. The storage unit 32 stores programs, calculation formulas for power consumption, measurement information, and accumulated calculation result data. The storage unit 32 also includes an accumulation calculation unit 34 that adds and accumulates multiple calculated results of electric energy consumption during the same trip, and a data collection and analysis unit 33 that adds, collects, and analyzes the accumulated results of electric energy consumed during a trip, the traveling location, and the distance traveled. The GPS module 38 can read the traveling location and distance by connecting to an external positioning satellite system 70. The communication unit 39 can connect to an external cloud server 80 via the Internet to upload data. The timer unit 37 can set and operate the multiple sensor units 36 to measure the voltage and current input to the battery unit 60, thereby calculating the period for calculating electric energy consumption, the period for the GPS module 38 to read the traveling location and distance from the positioning satellite system 70, and the period for the communication unit 39 to upload data. These timer units can also be used to perform the carbon emission calculation method of the present invention.

[0020] As can be seen from the above, the present invention uses the control module 100 of the present invention to read position information at a high frequency and calculate unit power consumption energy by measuring at a high frequency based on the voltage and current of the control module 100 input by the battery unit 60. Furthermore, once the cumulatively calculated unit power consumption energy becomes the cumulative power consumption energy, all of the cumulative power consumption energy during the journey and the corresponding location information can be uploaded to the cloud, which can then be converted into the carbon emissions of the journey. The high-frequency measurement and cumulative calculation method significantly improves the accuracy of the power consumption energy consumed by the moving vehicle during the journey, preventing erroneous estimation of the carbon emissions of each journey. Furthermore, edge computing technology reduces the bandwidth load when uploading to the cloud and improves the upload speed, further reducing the calculation, data storage, and data processing load on the cloud server. Furthermore, high-frequency measurement can be used to check whether the current and voltage of the motor 50 input by the control module 100 correspond to the fluctuations in the position information, thereby further verifying actual usage conditions. This reduces the scope for fraud and allows the carbon emissions of mobile vehicles to be truly and accurately calculated, which can be used to trade carbon credits for environmentally friendly mobile vehicles, thereby truly solving the problem of greenhouse gas reduction and effectively creating and revitalizing the environmentally friendly mobile vehicle industry.
