Just like the fuel consumption of fuel vehicles, endurance is one of the most critical performances of new energy models. We did not add one here because the mileage can not only reflect the hard power of the vehicle's continuous driving ability, but also reflect the soft power of the vehicle's electronic control system. At the same time, most consumers are often the first concern when choosing new energy models: "How many kilometers can this car run?" "Although charging conditions in many cities and regions are becoming more and more convenient, they are still inadequate compared to the amount of ownership. Moreover, if it is the kind of situation that charges for 10 hours and talks for 5 minutes, I believe that no amount of charging piles is enough, so in the final analysis, new energy models still rely on battery life to justify their own name.
Volkswagen is one of the most profound brands in the field of automobile manufacturing, and it is needless to say that in terms of traditional fuel vehicles, it is in a leading position in terms of development history and technical strength. This time, Volkswagen has extended its deep foundation in car manufacturing to the field of pure electric vehicles, and the birth of the ID brand is not only the rise of a new electric family, but also a manifestation of the brand's accumulation. This time, let's test the endurance strength of a star model ID4 X under the ID brand, the examination room is arranged in the light emission energy-saving room of the China Automobile Center, which is the endurance test laboratory of new energy models with top test equipment and test level in China, and the examination question it faces is the most reasonable working conditions and the most comprehensive CTLC China working conditions.
Here we briefly introduce the CLTC China working conditions, and the previous well-known electric vehicle endurance NEDC working conditions are different, CTLC is based on the actual road conditions in China to develop a series of cycle test standards, including low, medium and high three different speed cycle conditions in a stable environment, as well as isozoic conditions test items. The test process covers and simulates almost all the road environments used daily by domestic drivers, so the mileage results tested according to CLTC China conditions are more instructive and reference value for Chinese consumers.
The model used in this test is SAIC Volkswagen ID4.X 2021 Pro Jizhi long-lasting version, and the official data given by the battery is: NEDC has a range of 555km, a ternary lithium battery capacity of 83.4kWh, and a 100-kilometer power consumption of 16.2kWh. The motor equipped with this model is a permanent magnet/synchronous motor, with a maximum power of 150kW and a maximum torque of 310Nm, which can be described as full of vitality from the data point of view. Of course, the focus of this endurance test is endurance, and the battery capacity and mileage are far beyond the same level of models from the book, which makes the results of this CTLC working condition test more exciting.
Before the start of the cyclic working condition test, the tester will be the vehicle power full and placed in the test equipment, the environmental warehouse for the constant temperature and humidity setting, so that the battery, motor and other electronic control equipment work in the best state, to ensure the maximum degree of accuracy of the test results to the millimeter. According to the procedures of the CTLC test method, due to the large battery capacity of ID4.X, it is suitable for CTLC shortening method testing, so that the test conditions can be guaranteed in the same test cycle more times, the test sample is more complete, and the results obtained are more accurate, just like a light microscope, meticulous, and deeply excavate the endurance limit of ID4.X.
During the test, in order to compare the mileage of the table display, that is, the accuracy of the vehicle's own calculation of the remaining mileage, the instrument will record each interval of a certain mileage. At the end of the test, the actual remaining mileage at each record can be calculated by adding up each actual travel interval. In short, the table mileage has been subtracting, and the actual remaining mileage is to add each interval mileage after the test and accumulate it in reverse. The test began to record when the remaining 472km of endurance on the table, and after 32 interval recordings, the actual endurance was 466.68km, and the accuracy reached 98.87%! It should be known that in the initial state, the judgment of the vehicle's own endurance has been calculated according to the estimated power consumption of the previous best driving operation, and in the process of calculation, it does not know that it is in the strict CTLC test cycle, experiencing repeated tests of different speeds and different working conditions, which shows that ID4.X is the real "table" and "inside".
There is also a very interesting comparison in the interval record, the test interval is generally 15km, and in the first few intervals of the record, the number of kilometers reduced by the remaining mileage is about 3-4km higher than the actual number of kilometers traveled. However, with the increase of the driving distance, when the remaining mileage of the table is 182km, the actual remaining mileage is 182.55, reaching a state of infinite proximity. From the next recording interval, the number of meter miles began to be less than the remaining mileage, forming a "reverse difference", popularly speaking, that is, the endurance began to be rich, and then each interval record such a "reverse difference" will increase, until the table shows that the remaining mileage is 0, the actual endurance has more than 14km of power reserves. If you encounter extreme situations, this part of the endurance reserve is likely to allow the vehicle to travel to a position where it can be charged.
Finally, after all the conditions of the cycle test, ID4. X's driving range figure is fixed at 624km, and the electrical energy consumption per kilometer is only 0.139kWh! This extreme performance is almost perfect for a pure electric SUV model, not only needs a strong power reserve, but also requires the careful calculation of the motor, although it is the endurance test results obtained in the extreme economic state, but this performance is enough to cure the consumer's battery life anxiety.
ID4. X handed over a nearly full score in the circular working condition, and then, as the "improvement class" of CTLC's test project, the recommended test speed specified in the test standard for the isumetric test is 100km/h, which means that the tested vehicle must always be in a high-speed state. Maintaining driving at such a speed is tantamount to the vehicle has been in a state of running at a high speed, the test of the whole motor is maintained in a high output working mode, and the working intensity of the power consumption speed is not to be said.
We often hear electric vehicle owners say: "At high speed, the battery life will be discounted by half." "In this way, models with a range of less than 300km are struggling to drive at high speed and long distances." However, our concerns are obviously redundant, and after constant speed testing, ID4. X finally ran a high-speed endurance score of 438km and calmly walked out of the examination room, such a high-speed endurance performance is enough for consumers to break through the psychological barrier of long-distance driving again.
ID4. X can accept and perfectly perform itself in the CTLC test, in fact, in order to tell everyone its own excellent endurance, and behind the results is the support of excellent battery, motor, electronic control technology, as well as the overall performance of body structure, wind resistance optimization, chassis adjustment, etc. Finally, don't forget that ID4. X's fast charging time is only 40min, simply imagine, the high-speed 2-hour driving distance is about 200 kilometers, and then into the high-speed rest area for rest adjustment time can easily fill the battery, so ID4.X can meet a walk-and-go trip. Real endurance, strong enough!
