Average power consumption acquisition method, device, medium and electronic equipment

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application No. 202311230198.8, filed on September 21, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates to the technical field of electric vehicles, and in particular to a method, device, medium and electronic device for obtaining average power consumption. Background Art

[0004] A hybrid vehicle is a vehicle whose drive system is composed of two or more single drive systems that can operate simultaneously. The vehicle's driving power is determined by whether it is provided by a single drive system alone or by multiple drive systems together, depending on the actual driving state of the vehicle.

[0005] Hybrid vehicles generally fall into three categories: series hybrid vehicles, parallel hybrid vehicles, and parallel-parallel hybrid vehicles. A series hybrid vehicle primarily consists of an engine, generator, and drive motor connected in series to form the HEV (Hybrid Electric Vehicle) powertrain. A parallel hybrid vehicle's engine and drive motor are both powertrains, and the power of the two powertrains can be combined or output independently. A parallel-parallel hybrid vehicle is an electric vehicle that combines both series and parallel structures, primarily consisting of an engine, motor-generator, and drive motor.

[0006] The average power consumption of a hybrid vehicle can be used to evaluate its electricity economy. However, the method of calculating the average power consumption of a hybrid vehicle in related technologies fails to take into account the incremental power provided by the engine when connected in series or parallel, resulting in the power consumption displayed on the instrument panel being greater than the actual power consumption of the vehicle, which is not conducive to accurately calculating the average power consumption of the hybrid vehicle.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0026] Figure 1 shows a flow chart of a method for obtaining average power consumption according to some embodiments of the present disclosure, which can be executed by a device with computing and processing capabilities. Referring to Figure 1 , the method for obtaining average power consumption includes at least steps S1 to S5.

[0027] In step S1 , the power consumption and charge amount of the battery pack within a preset period of time, as well as the first driving mileage of the vehicle within the preset period of time are obtained.

[0028] In some embodiments, the power consumption of the battery pack within a preset time period can be obtained through a dashboard or a battery management system.

[0029] In the case of a series hybrid electric vehicle, the amount of charge to the battery pack during the preset period is the amount charged by the charging pile. In the case of a parallel-parallel hybrid electric vehicle, the amount of charge to the battery pack during the preset period is the sum of the amount charged by the charging pile and the amount of power generated by the vehicle's engine, where the amount of power generated by the engine-driven generator is the amount of power generated.

[0030] In some embodiments, the first mileage of the vehicle within a preset time period can be obtained through the instrument panel.

[0031] In step S2, the incremental power of the vehicle within a preset time period and a second driving mileage corresponding to the incremental power are obtained.

[0032] In some embodiments, the incremental power of the vehicle within a preset time period can be obtained based on the power consumption of the battery pack during a specific time period, wherein the specific time period can be a time period when the hybrid vehicle is in a series state, a time period when the hybrid vehicle is in a parallel state, or a time period when the hybrid vehicle is in an engine-starting state.

[0033] In step S3, the power consumption of the vehicle during the preset period is obtained based on the incremental power, and the power consumption and charge amount of the battery pack during the preset period.

[0034] The power consumption of the vehicle during the preset time period is calculated according to the above steps S1 to S3, eliminating the influence of the incremental power, so that the subsequent calculation of the average power consumption is more accurate.

[0035] In step S4 , a third driving mileage of the vehicle within a preset period is obtained based on the first driving mileage and the second driving mileage. The third driving mileage is a driving mileage corresponding to the power consumption of the vehicle within the preset period.

[0036] In step S5 , the average power consumption of the vehicle in the preset period is obtained according to the power consumption of the vehicle in the preset period and the third driving mileage.

[0037] In some embodiments, the power consumption of the vehicle during the preset period is obtained based on the incremental power, and the power consumption and charge amount of the battery pack during the preset period, including: calculating the sum of the power consumption and charge amount of the battery pack during the preset period to obtain the power consumption of the vehicle during the preset period; calculating the difference between the power consumption of the vehicle during the preset period and the incremental power to obtain the power consumption of the vehicle during the preset period, so that the calculated power consumption during the preset period excludes the incremental power.

[0038] In some embodiments, based on the first mileage and the second mileage, a third mileage of the vehicle within a preset time period is obtained, including: calculating the difference between the first mileage and the second mileage to obtain the third mileage of the vehicle within the preset time period, thereby eliminating the second mileage corresponding to the incremental power from the first mileage of the vehicle within the preset time period.

[0039] In some embodiments, the power consumption of the battery pack during a preset period is the difference between the initial power consumption of the battery pack and the final power consumption of the battery pack during the preset period. The initial power consumption of the battery pack during the preset period is the power consumption of the battery pack corresponding to the initial time point of the preset period, and the final power consumption of the battery pack during the preset period is the power consumption of the battery pack corresponding to the final time point of the preset period. For example, the preset period is from 3:00 PM to 6:00 PM on June 20, 2021, with the initial time point of the preset period being 3:00 PM on June 20, 2021, and the final time point of the preset period being 6:00 PM on June 20, 2021.

[0040] In some embodiments, if the vehicle is a series hybrid electric vehicle, the charge level of the battery pack during the preset period is the charge level at the charging station, and the incremental charge level during the preset period is the power consumption of the battery pack during engine operation. The power consumption of the battery pack during engine operation is the difference between the initial and final power levels of the battery pack during engine operation.

[0041] In some embodiments, the average power consumption of the series hybrid electric vehicle during a preset period is calculated according to the following formula:

[0042] , D p is the average power consumption of the vehicle during the preset period, D z is the charging capacity of the charging pile, D c is the initial charge of the battery pack within the preset period, D j is the final charge of the battery pack within the preset period, n is the number of times the engine is started, D fji is the final charge of the battery pack when the engine is started for the i-th time, D fci is the initial charge of the battery pack when the engine is started for the i-th time, L y is the first mileage, L fji is the mileage of the vehicle at the end of the vehicle's travel when the engine is started for the i-th time, D fci is the initial mileage of the vehicle when the engine is started for the i-th time.

[0043] The average power consumption during the preset period calculated according to the above formula (1) is the average power consumption of the series hybrid vehicle when the engine is not started. The incremental power consumption when the engine is started is eliminated, making the calculated average power consumption more accurate and convenient for evaluating the power economy of the series hybrid vehicle.

[0044] In some embodiments, when the vehicle is a parallel-parallel hybrid electric vehicle, the charge amount of the battery pack within the preset period is the sum of the charge amount of the charging pile and the power generation of the engine, and the incremental power within the preset period is the power consumption of the battery pack when it is connected in parallel with the engine.

[0045] In some embodiments, the power consumption of the battery pack when the engines are connected in parallel is the difference between the initial power consumption and the final power consumption of the battery pack when the engines are connected in parallel.

[0046] In some embodiments of the present disclosure, the average power consumption of a series-parallel hybrid electric vehicle within a preset period of time may be calculated according to the following formula:

[0047] D p is the average power consumption of the vehicle during the preset period, D z is the charging capacity of the charging pile, D f is the power generation of the engine, D c is the initial charge of the battery pack within the preset period, D j is the final capacity of the battery pack within the preset period, m is the number of engines connected in parallel, D bji D is the final capacity of the battery pack when the engines are connected in parallel for the i-th time. bciis the initial capacity of the battery pack when the engines are connected in parallel for the i-th time, L y is the first mileage, L bji is the mileage of the vehicle at the end of the journey when the engines are connected in parallel for the i-th time, D bci is the initial mileage of the vehicle when the engines are connected in parallel for the i-th time.

[0048] The average power consumption within the preset period calculated according to the above formula (2) is the average power consumption of the series-parallel hybrid vehicle in the pure electric state. The incremental power when the engine is connected in parallel is eliminated, making the calculated average power consumption more accurate and convenient for evaluating the power economy of the series-parallel hybrid vehicle.

[0049] In some embodiments, the above-mentioned average power consumption acquisition method can be implemented through a visual data modeling platform, including the following steps: obtaining the power consumption of the vehicle in the preset period based on the power consumption and charge amount of the battery pack in the preset period, and the incremental power in the preset period; obtaining the third mileage of the vehicle in the preset period based on the first mileage and the second mileage, and the third mileage of the vehicle in the preset period is the mileage corresponding to the power consumption of the vehicle in the preset period; obtaining the average power consumption of the vehicle in the preset period based on the power consumption and the third mileage of the vehicle in the preset period.

[0050] In some embodiments, the visual data modeling platform can obtain the power consumption and charge amount of the vehicle's battery pack within a preset time period and the first mileage of the vehicle within the preset time period through the Greenplum database, and obtain the incremental power within the preset time period and the second mileage corresponding to the incremental power through the Greenplum database. Data is transmitted between the Greenplum database and the vehicle through an intermediate layer. An MQTT client is provided on the vehicle end. The intermediate layer includes an MQTT protocol and Kafka. The MQTT client transmits data to Kafka through the MQTT protocol, and Kafka transmits data to the Greenplum database.

[0051] The average power consumption acquisition method implemented through the visual data modeling platform eliminates the power increment within the preset time period, making the calculation of the vehicle's average power consumption within the preset time period more accurate and facilitating the evaluation of the power economy of hybrid vehicles.

[0052] The present disclosure also provides an average power consumption acquisition device. FIG2 shows a block diagram of the average power consumption acquisition device according to some embodiments of the present disclosure. Referring to FIG2 , the average power consumption acquisition device 100 includes: a first acquisition unit 101, for acquiring the power consumption and charge amount of the battery pack within a preset time period, and a first mileage of the vehicle within the preset time period; a second acquisition unit 102, for acquiring the incremental power of the vehicle within the preset time period, and a second mileage corresponding to the incremental power; a first acquisition unit 103, for acquiring the power consumption of the vehicle within the preset time period based on the incremental power and the power consumption and charge amount of the battery pack within the preset time period; a second acquisition unit 104, for acquiring a third mileage of the vehicle within the preset time period based on the first mileage and the second mileage, the third mileage being the mileage corresponding to the power consumption of the vehicle within the preset time period; and; a third acquisition unit 105, for acquiring the average power consumption of the vehicle within the preset time period based on the power consumption and the third mileage of the vehicle within the preset time period.

[0053] In some embodiments, the first obtaining unit 103 is configured to: calculate the sum of the power consumption and the charge amount of the battery pack during a preset period to obtain the power consumption of the vehicle during the preset period; and calculate the difference between the power consumption and the incremental power of the vehicle during the preset period to obtain the power consumption of the vehicle during the preset period.

[0054] In some embodiments, the first acquisition unit 101 is configured to: when the vehicle is a series hybrid vehicle, use the charging amount of the charging pile as the charging amount of the battery pack within a preset time period, and the incremental power within the preset time period is the power consumption of the battery pack when the vehicle's engine is working.

[0055] In some embodiments, the third obtaining unit 105 is configured to calculate the average power consumption of the vehicle within a preset period according to the following calculation formula:

[0056] D p is the average power consumption of the vehicle during the preset period, D z is the charging capacity of the charging pile, D c is the initial charge of the battery pack within the preset period, D j is the final charge of the battery pack within the preset period, n is the number of times the engine is started, D fji is the final charge of the battery pack when the engine is started for the i-th time, D fci is the initial charge of the battery pack when the engine is started for the i-th time, L y is the first mileage, L fji is the mileage of the vehicle at the end of the vehicle's travel when the engine is started for the i-th time, D fci is the initial mileage of the vehicle when the engine is started for the i-th time.

[0057] In some embodiments, the first acquisition unit 101 is configured to: when the vehicle is a parallel-parallel hybrid electric vehicle, the sum of the charging amount of the charging pile and the power generation of the vehicle's engine is used as the charging amount of the battery pack within a preset time period, and the incremental power of the vehicle within the preset time period is the power consumption of the battery pack when the engine is connected in parallel.

[0058] In some embodiments, the second acquiring unit 102 is further configured to use the difference between the initial power level and the final power level of the battery pack when the engines are connected in parallel as the power consumption of the battery pack when the engines are connected in parallel.

[0059] In some embodiments, the average power consumption of the vehicle during a preset period is calculated according to the following formula:

[0060] D p is the average power consumption of the vehicle during the preset period, D z is the charging capacity of the charging pile, D f is the power generation of the engine, D c is the initial charge of the battery pack within the preset period, D j is the final capacity of the battery pack within the preset period, m is the number of engines connected in parallel, D bji D is the final capacity of the battery pack when the engines are connected in parallel for the i-th time. bci is the initial capacity of the battery pack when the engines are connected in parallel for the i-th time, L y is the first mileage, L bji is the mileage of the vehicle at the end of the journey when the engines are connected in parallel for the i-th time, D bci is the initial mileage of the vehicle when the engines are connected in parallel for the i-th time.

[0061] In some embodiments, the above-mentioned first obtaining unit 103, second obtaining unit 104 and third obtaining unit 105 are implemented through a visual data modeling platform, and are implemented by dragging and dropping on the visual data modeling platform. For example, the data to be used is configured on the data side, and then the data is dragged to the calculation side, and the data is strung together in sequence using a visual operator component, and finally the report data of the average power consumption is generated and written back to the data source. The generated results are visible. It can be seen from the entire calculation process that no native code is written, and the power consumption calculation of hybrid vehicles in different hybrid modes is realized through visual drag operations.

[0062] In some embodiments, the first acquisition unit 101 and the second acquisition unit 102 acquire data through the Greenplum database, and data is transmitted between the Greenplum database and the vehicle (i.e., the vehicle side) through an intermediate layer. An MQTT client is provided on the vehicle side, and the intermediate layer includes the MQTT protocol and Kafka. The MQTT client transmits data to Kafka through the MQTT protocol, and Kafka transmits data to the Greenplum database.

[0063] In some embodiments, when the vehicle and the cloud communicate, due to the problems of network latency and unstable network usage scenarios, it is necessary to use a message protocol to design a short, asynchronously sendable message component. Using MQTT to collect raw data can solve the above problems. After the message is collected from the vehicle and stored in the MQTT client, because MQTT cannot support querying by message generation time and does not support the semantics of exact consumption, Kafka is used for message transfer. Kafka supports distinguishing messages according to the order of time (the business system can customize the time period to pull semaphore data) and provides the semantics of exact consumption (it can ensure that the business system can obtain data and obtain it only once). Therefore, using Kafka here can ensure the data accuracy of the business system and provide the ability to independently select and view signals within a specified time range. Finally, the semaphore is stored in the Greenplum database, rather than the relational databases such as MySQL traditionally used in the industry. The reason is that the Greenplum database provides the ability to read and write billions of data in a distributed manner compared to relational databases. Modern electric vehicles have hundreds of thousands of signal types, and the frequency of signal data generation is very high. Currently, it is known that the time it takes to generate a piece of signal data can be shortened to 50ms. Therefore, as the number of vehicles expands rapidly and the number of vehicle-side domain controllers increases, the signal frequency becomes faster and faster. Traditional relational databases can usually only support hundreds of thousands of data reads and writes per second and lack distributed read and write capabilities. In the real-time computing process for users, it will cause huge delays and read and write performance bottlenecks. By adopting the Greenplum database, it is easy to cope with the updates and developments of the vehicle-side architecture.

[0064] In summary, the hybrid transmission of MQTT and Kafka and the final landing in the Greenplum database effectively solves the pain points of communication between the vehicle and the cloud, such as the unstable vehicle-side network environment, the cloud's inability to accurately consume and independently select any time period to read messages, and data storage performance bottlenecks.
