Description

TECHNICAL FIELD

[0001] The present application relates to the field of new energy vehicle application technology, in particular to a pure electric vehicle comprehensive energy consumption and endurance evaluation method, device, equipment and medium. BACKGROUND

[0002] In recent years, new energy vehicles have developed rapidly. It is crucial to reasonably evaluate the energy consumption and endurance level of pure electric vehicles, which not only provides important performance data reference for consumers to purchase vehicles, but also lays a foundation for the overall energy consumption improvement of the automobile industry.

[0003] At present, the energy consumption and endurance declaration data of domestic pure electric passenger cars are tested according to the national standard GB / T 18386.1-2021. The test condition refers to GB / T 38146.1-2019 Chinese Automobile Driving Cycle Part 1: Light Duty Vehicle, referred to as CLTC condition, and the test temperature is set to 23℃. The energy consumption calculation puts more than 90% of the proportion in the third and fourth hot engine cycles at the end of the test. The discharge capacity of the vehicle battery is cut off when the vehicle cannot follow 100km / h.

[0004] The above test method provides a unified test specification for the energy consumption and endurance declaration of domestic pure electric vehicles, but the test condition, test temperature and vehicle power usage boundary are relatively single, and cannot represent the usage level under the wide temperature range, different conditions and travel habits of domestic users. In the actual vehicle driving process, the high and low temperature limit environment deviating from 23℃ will lead to the increase of vehicle air conditioning power consumption; under the condition of low temperature in winter and even extremely low temperature in northeast China, the battery power will be significantly reduced; the cold state energy consumption data of the vehicle in daily short distance travel is also quite different from the hot state energy consumption level under standard test, and this difference is more obvious in winter; different travel scenarios also lead to certain differences between actual driving conditions and standard conditions; the actual power usage window of users is usually lower than 80% or even 70%. The foregoing factors will all cause a large gap between the actual usage energy consumption and endurance of users and the nominal data, causing complaints and anxiety of users in the actual driving process.

BRIEF DESCRIPTION OF DRAWINGS

[0037] Figure 1 is a flowchart of the pure electric vehicle comprehensive energy consumption and range evaluation method of the first embodiment of the present application. DETAILED DESCRIPTION

[0038] The application will be further described in connection with the specific embodiments. It should be understood that these embodiments are only used to illustrate but not to limit the scope of the application. Furthermore, it should be understood that after reading the content of the present application, those skilled in the art can make various modifications or changes to the application, and these equivalent forms also fall within the scope defined by the appended claims.

[0039] The first embodiment of the present application relates to a method for evaluating the comprehensive energy consumption and the cruising range of a pure electric vehicle, as shown in the following steps: Figure 1

[0040] Step 1, collect the vehicle driving information of the user under different travel conditions, and form the road spectrum information of different travel conditions.

[0041] In this step, the travel conditions are divided into urban travel conditions, suburban travel conditions and high-speed travel conditions according to the differences of the travel conditions. The vehicle driving information of the user under each travel condition is collected, including travel time, travel distance, travel speed, battery power usage interval, annual travel temperature, etc., and the data collection frequency is not less than 10Hz. According to the information collected under each travel condition, the universal urban condition road spectrum curve, the suburban condition road spectrum curve and the high-speed condition road spectrum curve are formed; wherein the horizontal coordinate of the road spectrum curve is the travel time t (unit: s), the vertical coordinate is the travel speed v (unit: km / h), and the data interval is 1s.

[0042] Step 2, determine the different temperature range of energy consumption test, and define the vehicle test boundary.

[0043] In this step, according to the influence degree of temperature on energy consumption, it is divided into five temperature ranges, which are: spring and autumn season range, summer season range, ordinary winter season range, cold winter season range and extremely cold winter season range. In this embodiment, the temperature interval of the spring and autumn season range is 10℃~30℃, i.e. [10℃, 30℃); the temperature interval of the summer season range is 30℃ or more, i.e. [30℃, +∞); the temperature interval of the ordinary winter season range is 0℃~10℃, i.e. [0℃, 10℃); the temperature interval of the cold winter season range is -10℃~0℃, i.e. [﹣10℃, 0℃); and the temperature interval of the extremely cold winter season range is -10℃ or less, i.e. (﹣∞, ﹣10℃).

[0044] The vehicle test boundary in this step includes the temperature test boundary, the power test boundary and the air conditioner usage.

[0045] ​Temperature test boundary: In order to simplify the test process, the representative temperature points in each temperature range are selected as the test energy consumption benchmark. 20°C is selected as the test temperature in spring and autumn, 35°C is selected as the test temperature in summer, 5°C is selected as the test temperature in ordinary winter, -7°C is selected as the test temperature in cold winter, and -20°C is selected as the test temperature in extremely cold winter.

[0046] Vehicle power test boundary: The vehicle test power range is selected as the state of charge range of 50% to 60% (the battery recycling ability is limited when the power is too high, and the power is limited when the power is too low).

[0047] Vehicle air conditioner usage: Considering the actual user scenario, the air conditioner is kept on in the full temperature range of the test specification, and the air conditioner is set to Auto 22°C. Before the test starts, the vehicle is charged to the required power and immersed for 12 hours.

[0048] Step 3: Determine the energy consumption test condition and battery discharge condition based on the road spectrum information of different travel conditions.

[0049] Since the actual user travel time is different, this embodiment defines less than 30 minutes as a cold driving state, and more than 30 minutes as a hot driving condition. In actual contact, the high-speed condition scenario is almost a hot engine condition. In order to fully test the cold and hot energy consumption data of the vehicle under different conditions, two test road spectrums of urban and suburban areas are developed. Since the high-speed condition only carries out hot state test, the high-speed condition test is placed after the urban hot engine condition. The urban condition test cycle consists of three urban cycles and one high-speed cycle. Among them, the first urban cycle represents the energy consumption level of the vehicle under cold state, which means the urban cold engine energy consumption test condition; the second urban cycle represents the energy consumption level of the vehicle under hot engine transition state, and the third urban cycle represents the energy consumption level of the vehicle under hot engine state. The second urban cycle and the third urban cycle mean the urban hot engine energy consumption test condition, and the vehicle energy consumption is equal to the total energy consumption of the energy storage device / the hub travel mileage; the high-speed cycle represents the energy consumption level of the vehicle under high-speed state, which means the high-speed energy consumption test condition. Similarly, the suburban condition test consists of three suburban cycles. The first suburban cycle represents the energy consumption level of the vehicle under cold state, which means the suburban cold engine energy consumption test condition; the second suburban cycle represents the energy consumption level of the vehicle under hot engine transition state, and the third suburban cycle represents the energy consumption level of the vehicle under hot engine state. The second suburban cycle and the third suburban cycle mean the suburban hot engine energy consumption test condition. In order to quickly discharge and shorten the test period, the discharge condition in this embodiment adopts constant speed 100km / h; before discharging, the vehicle is immersed in the test temperature environment for 12h to 15h to ensure that the vehicle battery temperature, oil temperature, and water temperature are consistent with the test environment.

[0050] Step 4, test the vehicle basic energy consumption data in the different temperature ranges and different energy consumption test conditions within the vehicle test boundary, and obtain the basic energy consumption data as shown in Table 1. All energy consumption data is in units of kW.h / 100km, and the results are rounded to two decimal places.

[0051] Table 1 Basic energy consumption data table

[0052]

[0053] Step 5, test the actual power level of the vehicle in different power usage windows in the different temperature ranges and battery discharge conditions.

[0054] The power level is based on the state of charge (SOC) level displayed on the vehicle instrument or entertainment screen. Each 10% interval is recorded as a node, and the test is stopped when the displayed SOC is 0. Therefore, the basic battery power data obtained after completing the test is shown in Table 2. All test power is in units of kW.h, and the results are rounded to two decimal places.

[0055] Table 2 Basic battery power data table

[0056]

[0057] Step 6, calculate the vehicle actual usage scenario energy consumption based on the travel temperature range proportion, travel condition proportion, travel power usage interval, and travel time in the actual usage scenario input, and combine the vehicle basic energy consumption data in the different temperature ranges and different energy consumption test conditions. The vehicle actual usage scenario energy consumption includes single-temperature-zone full-condition comprehensive energy consumption level and all-year all-temperature-zone full-condition comprehensive energy consumption level.
