Hey this car circle has been very lively recently, the steering column is different at home and abroad, which makes many people have a headache, it is not easy for me to buy a car, how can the routine be so deep? In fact, the main information is not equal, let alone parts, this ancient fuel vehicle 100 kilometers fuel consumption virtual standard, now there are new energy vehicle mileage in the silly indistinguishable ah!
People who have bought a tram may have a deep understanding, when buying said that the maximum endurance is 500 kilometers, the comprehensive endurance is 350 kilometers, and the result is actually a good guy, 250 kilometers! Provincial travel seconds to suburban travel and seconds to commute to work! This makes people more anxious, ah, today we come to popularize the three major routines of the mileage of new energy vehicles! Maybe one day you will buy a car and use it!
First of all, let's see, now the promotion of electric vehicle mileage is generally two indicators, one is called constant speed endurance, one is called comprehensive working conditions, many signs EV500 km of these cars, in fact, is the data of constant speed endurance, you look at this time charge here the number of distances is very far, but do you know what this means? What does it mean that the car runs in circles around the field at a uniform speed of 60 kilometers per hour until the car runs out of electricity? No traffic light parking start, no acceleration overtaking, no mutual civilization with other cars on the road, that is equivalent to our salary into 3000, and then said I can save 36,000 a year! So ah, this number of constant speed endurance you just listen to, don't take it seriously.
So what's the main thing to look at? Look at the overall working conditions. This comprehensive working condition is relatively more reliable, but it is not so perfect, after all, it is only a test, and there is always a difference between the actual use, the key is the size of the difference. Now there are two mainstream working condition tests, one is NEDC and the other is CLTC. First, let's look at how this NEDC is measured.
NEDC is measured on the shelf, the car is first fixed to a treadmill, this treadmill simulates a series of operations in urban areas, suburbs, including acceleration and deceleration on the high speed, and then put a hair dryer on the front of the car to simulate wind resistance. But ah, the test inside the people put what air conditioning, sound, headlights, heated seats, etc., in short, all the electricity things for you to turn off, all for you to save. Therefore, nedc test results are still an ideal state, and this is still the introduction of European standards, road conditions and temperatures and the like are also different from the domestic.
In addition, the CLTC, which is our own domestic research and development standard, collected the driving data of a large number of cars in more than forty cities in China, but this test method is almost copied from THEDC, so the test results are almost exactly the same, and even many times the data will be higher. For example, the original NEDC mileage of the new energy vehicle measured 525 kilometers, and the result was tested by the CLTC, 545 kilometers! The conclusion is that these two test results are not outrageous, but there is a deviation from the actual mileage, and at most the data looks better when everyone advertises the product.
The most reliable thing is that after you buy a car, the mileage displayed on the display screen of this car instrument, this mileage is in accordance with the EPA standard, what is the EPA standard? It is the U.S. Environmental Protection Agency's standard, which is by far the closest standard to the actual driving mileage, how close? Probably that is, the mileage displayed on the screen is a 90% discount, which is the actual mileage.
That business advertises two sets of standards, there is a set of standards in the car, and the actual use is another set, is this not a nesting doll? So, our Ministry of Industry and Information Technology came out and said, saying that we have to be unified, we have to actually stipulate that by 2025, all new energy vehicles in the country will be unified with a standard called WLTC working condition test, so what is this? This is actually the use of NEDC test methods, combined with domestic road conditions, temperatures and traffic jams, the test speed is crazy to add and subtract brake stops, and the test time is extended by ten minutes, so the space for moisture is much smaller. However, in addition to these, there is an additional height test link, the test speed is more than 130 kilometers per hour, but the maximum speed limit of our domestic high-speed is only 120, so the reliability of the overall final test results will still affect a little.
Let's sum up, buy new energy vehicles different working conditions test, constant speed endurance is the most watery, and then EPA test > WLTC test > NEDC test > CLTC test, but how far the car can run, the key depends on the place, Guangzhou hot spot air conditioning open more, northeast cold electricity will be consumed fast, Chongqing mountain city climbing more will also consume electricity, then what to do? In short, if you buy a tram, you want to think that the actual mileage can have 1/3 of the business advertised by the business is already very good!
