News from this newspaper (Reporter Du Xin) The cruising range marked on the publicity page is 545 kilometers, but the displayed mileage on the car is only 440 kilometers; some new energy vehicles have "discounted" cruising range in winter, and the car marked with 535 kilometers can only run 326 kilometers A reporter from "Workers Daily" recently found that there are at least 3 sets of battery life standards for new energy vehicles on the market.
When the reporter browsed the publicity pages of major new energy car companies, they found that different car companies have different battery life standards. Generally, the corresponding test methods are indicated in a line of small characters below the cruising range, mainly including NEDC (new standard European cycle test) and CLTC. (Chinese light vehicle driving conditions) two.
In addition, the same car company may also use different standards for the mileage marking of different vehicles.
According to public information, NEDC is a European standard, and the test method includes 4 traditional urban road driving conditions and suburban driving conditions.
CLTC uses a large amount of data of Chinese cars on the road, adding a wider range of road conditions, including urban, suburban and high-speed driving conditions.
Industry insiders said that the road conditions, driving habits, and climate conditions in my country are very different from those in Europe. Moreover, because the test method is too simple compared with the actual driving conditions, the test results of NEDC are watery, and the test results of CLTC are quite different. Closer to the actual road conditions in China.
However, from the perspective of new energy vehicles using the CLTC standard, there is still a large gap between the nominal mileage and the actual mileage.
An SUV produced by a foreign car company has a nominal mileage of 525 kilometers for NEDC and 545 kilometers for CLTC under the same battery conditions, while the displayed mileage on the actual vehicle is less than 440 kilometers.
The salesperson of the car company said that in October last year, the cruising range on the promotional page was changed from the NEDC standard to the new CLTC standard, and the displayed mileage on the car adopted the EPA (United States Environmental Protection Agency) standard, which is closer to Actual miles driven.
"One set of standards is used for publicity, and another set of standards is used for real cars. A car has 3 sets of battery life standards, and car owners can't tell the difference. It is difficult to figure out the difference between each set of standards." Mr. Chen, owner of Beijing car To put it bluntly, no matter which set of standards it is, the nominal mileage cannot be achieved in actual driving.
In winter, when the battery is cold, the actual driving range is greatly reduced.
On March 12, the results of the comparison test of the low-temperature cruising range of electric vehicles jointly released by the Beijing-Tianjin-Hebei consumer associations showed that the measured low-temperature cruising range of 10 prototype vehicles was "discounted" compared with the declared value of normal-temperature cruising range.
Among them, the declared value of the normal temperature cruising range of a new energy vehicle is 535 kilometers, and the measured value of the low temperature cruising range is reduced to 326 kilometers.
The standard is not uniform and there is a gap with the actual cruising range, which is easy to make the car owner feel a sense of gap.
In the interview, many car owners admitted frankly that they hope that car companies will stop playing standard routines, exaggerating the cruising range, unify the standard as soon as possible, and give more realistic battery life data in combination with different regions, seasons, road conditions, etc.
