Photoelectric measurement! How long is the Benz EQC?

Posted 2020-09-02 00:00:00 +0000 UTC

EQC was launched by Beijing Benz. It is an original German luxury electric vehicle with a length of 4774mm. The high-end model was put on the market in the first stage. The manufacturer's suggested retail price is 5798-622800 yuan. As for the one just issued on April 23, it was announced on the same day that from now on to June 30, 2020, the original quota of 16000 yuan will continue to be enjoyed for purchasing EQC, and the price after subsidy will be 5638-606800 yuan. So, what is the endurance strength of this car? Recently, electric colt used EQC to test its endurance strength from multiple angles. Next, take a look at the results. Daily driving in downtown area: how long does it take to get to Puwo? First look at the basic data of EQC: the group capacity is 79.2kwh, the vehicle weight is 2.4t, and the NEDC has a endurance of 415km. Note that the 79.2kwh battery is available power, in addition to which there is reserve power in the battery. Even if the remaining instrument endurance is zero, it can still drive about 20km, which is enough to make you reach the nearest in the urban area. At 12.27 noon, the remaining endurance of the instrument is 374km, and the remaining power is 7 / 8 (about 87%). As shown above. See here you may ask, 79.2kwh battery pack, the temperature outside the window is 27 degrees, why the endurance is only 374km? In this introduction, the endurance of Benz EQC is a dynamic endurance display, rather than a simple display of the endurance mileage determined under the NEDC standard. The principle of normal NEDC endurance display is very simple, that is, after full charge, the NEDC endurance value is as much as the meter shows km. Dynamic endurance is not the case. According to the factors such as temperature, driving habits, last driving characteristics, air conditioning size, etc., it dynamically calculates the endurance number, which is displayed on the instrument panel, giving the driver the most actual endurance information. Therefore, the dynamic endurance display number will be smaller than the NEDC endurance display number. For example, model 3 is a dynamic endurance display mode. After full charge, the instrument displays 480-500km, but NEDC endurance is 600 + km. The dynamic endurance of long endurance version is about 450km, but the endurance of NEDC is 575km. To get back to the point, take a look at the results of the whole course and section of the photoelectric test of Benz EQC. The photoelectric test was carried out on the Fifth Ring Road in Beijing. The total length of Wuhuan road is 98.58km. For the convenience of calculation, it is calculated as 99km. Here are the results of each circle. The first lap results can be seen from the table: the performance in this circle is quite awesome, which has consumed 75KM's endurance and actually runs 99km. The true rate of endurance is 132%! Maybe because the temperature is gradually rising, the driving speed is relatively stable. When the computer calculates the remaining endurance, it gives an optimistic prediction. The figure above shows the instrument display when starting, and the figure below shows the instrument display after driving five circles (99km). The figure below shows that the power consumption per 100 km is 15.9kwh/100km, which is lower than the officially announced power consumption of 19.9-20.1kwh/100km. The second lap result is more awesome, which has consumed the 79km mileage, actually 99km, and the real rate of life is 125%. The reason is the same. The driving mode is stable and the ambient temperature is high. Computer calculation is optimistic. As shown in the figure below, the 100km power consumption of this circle is 15.7kwh/100km, lower than that of the previous circle. In the third lap, the result consumed 96 km of endurance, and actually drove 99 km. The real endurance rate still exceeded 100%, reaching 103%. However, the result is lower than the first two laps. It may be related to the low temperature and the decrease of battery power. There is not much food left, and the calculation of the computer is becoming cautious and conservative. It's a bit like a central bank governor. However, the power consumption level in this circle is still 15.7kwh/100km. The fourth lap results the fourth lap results have some changes. The actual driving distance is 99 km, and the real endurance rate is 86%. There may be three reasons: first, the temperature drops further at 5-6 p.m.; second, the battery power consumption is fast running out, and the computer calculation is more conservative; third, the arrival of the evening peak, frequent start and stop increases the power consumption. Of course, the arrival of the evening peak also makes this test more close to the real use scenario and more able to detect the real endurance strength of EQC. After driving four laps on the Fifth Ring Road from the start to 0, brother Dianju drove EQC into Wangjing and drove on the urban road until the endurance mileage changed to 0. I'm not afraid to go to 0, because it has a reserve of electricity and can drive some distance. Finally, when the endurance is 0, the total mileage is 402km. As shown above. The following table shows the total results of the whole journey from departure to endurance: from the perspective of the whole journey test, the real endurance rate of EQC is 107%, which consumes 374km of endurance and actually drives 402km when the total power is seven eighths (about 87.5%). It was more than expected. This is the charm of dynamic endurance display mode, which will not falsely report results, and then quickly power down and throw you on the road. It will tell you the real endurance strength and avoid half lying on the ground. Therefore, this kind of endurance display has become a trend. How far can I travel from 0 to lie in nest? As mentioned above, backup power is reserved in EQC battery. The EQC can still drive for several kilometers even when the indicated endurance is 0. So, how many kilometers can it travel? Brother Dianju decided to challenge. In the evening, on the road where people and cars are rarely to reach, the electric colt drove the EQC with the remaining endurance of 0, and carried out a lie down test. At first, brother Dianju drove cautiously for fear of breaking down in the middle of the road. As a result, if you wait left and right, you will not lie in the nest. Later, the speed was increased. Finally, after 20 km driving, at 10.14 p.m., the EQC meter showed that the high-voltage battery was out of power, and then lost power. I followed the inertia to park it in the roadside parking space. During this period, the vehicle speed is 15-60km / h. As shown in the figure above, it starts from 0 endurance and ends in complete prostration. The driving mileage of EQC has changed from 402km to 422km, with a total of 20km. This 20km is enough to be found in the city. The results are as follows: from this, the total endurance of EQC can be calculated. That is to say, EQC uses 87% of the electricity and actually drives 422km before it gets to the ground. According to this ratio, if the power is charged to 100%, the driving mileage is about 450km-480km. The officially announced NEDC endurance of EQC is 415km. The comparison between the two shows that under the above conditions, the actual endurance capacity of EQC exceeds its NEDC endurance performance. As a traditional German enterprise, Mercedes Benz has obviously done relatively rigorous, even conservative, in the calibration of endurance. Of course, from another point of view, this "conservatism" also ensures the consistency of its electric vehicle products in the endurance mileage, and ensures that most customers can reach this endurance level in different scenarios, which can solve the problem of users' mileage anxiety. In the actual driving process, in the face of mileage anxiety, whether the mileage of electric vehicles is accurate to 400 km or 500 km, obviously there is no fundamental difference in a more reliable display environment. This is the feature of dynamic endurance display: conservative estimation of endurance mileage, giving the driver the most stable endurance information. However, the problem is that the number of endurance is small. Consumers who don't understand electric cars think the endurance strength of this car is not good when they see that the endurance number is too small. In fact, this kind of car is more honest, to be honest. Summary: how far can EQC run in urban daily driving? First of all, let's compare the differences among the three electric models with similar tonnage. Compared with the above table, it can be found that Benz EQC is equipped with 79.2kwh battery pack and es8 is equipped with 70kwh battery pack, but both of them have the same vehicle weight and NEDC endurance. However, in general, with the increase of vehicle weight, the endurance will be reduced. In addition, EQC and its vehicle weight are almost the same. The battery capacity is only 20 kwh less, but the NEDC endurance of modol x is 160 km more. Under normal circumstances, driving a 2.4 tonnage vehicle, 20kwh power can increase the endurance of 120km. This also shows that: compared with the opponent, EQC's NEDC condition endurance is more solid. In a word, the test has both urban road conditions and late peak road conditions, which is very close to the daily commute of the city as a whole. The endurance of EQC 415km under NEDC condition is enough to meet the daily commute of the city. If urban driving is the main driving mode, the actual driving scenario will be presented to the greatest extent, and the endurance can reach about 450km. If it is "golden feet", the endurance can be longer. In particular, after EQC's endurance is 0, the 20km emergency endurance stored in the battery is enough to find the charging pile in the city, which is more reassuring. How far can EQC run at high speed between cities? In the last photoelectric endurance test, the speed was concentrated around 80km / h, which was not enough to show the overall road condition endurance. It's just time to go to Daxing airport. I tested the high-speed endurance by the way. First look at the results from Yanjiao to Daxing airport. Starting at 3 p.m., go straight to Tongyan Expressway from Yanjiao, take the East Sixth Ring Road and the South Sixth Ring Road, enter Daxing Airport Expressway, and soon arrive at the Star Post charging station of Daxing airport. A total of 106KM of endurance has been consumed, and 82km has been actually driven. According to the calculation of the real rate of endurance, this EQC can drive 341km (443 times 77%). Because the power is not fully charged at the time of departure, if fully charged, it is expected to drive 350km. Then look at the results from Daxing airport to Yanjiao. This time, the electricity was charged to 99%. The range before departure is 447km. After returning to Yanjiao, it consumed 99km of endurance and actually drove 76km. The true rate of endurance is 76.7%. According to this calculation, EQC can drive at high speed after being fully charged, with a endurance of 343km (447 times 76.7%). These two journeys are similar to the speed of the vehicle, and the results are almost the same. From this, it can be calculated that under the above conditions, EQC is mainly driven by daily driving mode and high-speed driving, and the driving mileage after full charge is about 343-350km. If you are a golden foot, drive a little bit more frugal and attentive, and the mileage will be increased. Driving at high speed will reduce the range, especially for the electric SUV with a weight of 2.4 tons. In the past, model X was tested at high speed by electric colt, which drove at high speed from Beijing to Changli, Hebei Province. Some models were worse than this. EQC's score is about 84% of its NEDC endurance (415km). For this tonnage of electric vehicle, it's good to drive at high speed over 80% of NEDC's endurance. Rescue after crouching, please don't imitate! After the last pit test, I experienced the rescue service by the way. Mercedes Benz provides five services for EQC, including star steward, star post, star escort, star accompanying, star assistant, etc. Star escort is free rescue, including towing and charging. That night, I tried star escort first. Press the red SOS emergency call on the top of the car and it will be ready soon. It's 10 o'clock in the evening. The staff on duty are all there. The service attitude is also very good. After I explained the situation, the staff on duty confirmed the model, address, fault, phone number and the owner's situation, and then went to contact the rescue trailer and 4S shop. About 20 minutes later, the trailer and the rescue 4S shop all contacted. However, because of the impact of the new crown epidemic, coupled with the near midnight 12 o'clock, the actual rescue has increased many difficulties. Finally, the rescue workers dragged EQC to Penglong Ruixing Benz 4S store in Laiguangying. However, the trailer will come from west 3rd Ring Road, about 40 minutes. At night, the 4S store staff have been off work. After towing the car, it can only be charged tomorrow. I calculated that it would take 40 minutes for the trailer, 20 minutes for the car, 30 minutes for the journey to the store, and 1-2 hours for the charging. It's 2 a.m. after all. I asked Wei Lai to power on again. Someone called after the software was ordered, the service attitude was also very good, 380 yuan a door-to-door charging. However, due to emission restrictions, the car in the urban area of Weilai is lithium iron phosphate electric vehicle, and there was only one car during the outbreak. When the phone is connected, this rescue
