It is said to be four or five hundred kilometers, but actually two or three hundred kilometers. The reporter of "Xinhua viewpoint" found that many new energy vehicle manufacturers have advertised "ultra long range", but consumers often find that the range will shrink after buying a car, and some are only half of the nominal range. Complaints about the discount of the range of pure electric new energy vehicles have long been common. (Beijing Youth Daily, March 17) When purchasing new energy vehicles, the majority of consumers attach great importance to the mileage of the vehicle. In recent years, China's new energy vehicle industry has performed brilliantly, with rapid growth in production and sales. The publicity of "super long endurance" of automobile manufacturers has played a great role. However, while the official range is increasing, there have been doubts about the false standard and untrue. According to the user survey of jundi and chedi, a market research and consulting organization, more than half of the surveyed car owners have never actually experienced the mileage told by the manufacturer. For many car owners, the "super long endurance" described by the manufacturer is just "flowers in the water, moon in the mirror". Some car owners even summed up their experience. Taking the mileage claimed by the manufacturer as the base, "30% discount" is the actual mileage at ordinary times, and "50% discount" is the mileage in winter. The analysis of complaints received by the National Consumer Association in 2021 released by the China Consumer Association shows that complaints related to new energy vehicles are gradually increasing. Among them, "the reduction of endurance mileage, especially the fast loss of endurance under low temperature in winter" is one of the main problems of consumer complaints. In March this year, the Beijing Consumer Association released a comparative test on the low-temperature range of electric vehicles. All the 10 sample vehicles tested had a low-temperature "power failure" and a "discount" on the range. At present, the mileage published by new energy vehicle manufacturers generally uses NEDC (new European cycle test) standard test. The test results are obtained under relatively ideal conditions such as temperature and driving habits, which belongs to "rational endurance". However, car companies often avoid this in publicity. In websites and posters, they only use small characters to explain in marginal corners, which is difficult for consumers to notice. According to the law on the protection of consumers' rights and interests, consumers have the right to know the true situation of the goods they buy and use or the services they receive. Business operators shall provide consumers with true and comprehensive information about the quality, performance, purpose and term of validity of commodities or services, and shall not make false or misleading publicity. "Ideal endurance" can not truly reflect the actual situation of new energy vehicles and the actual experience of users, infringe on consumers' right to know and easily mislead consumers. In February last year, the State Administration of market supervision and the State Standardization Administration approved the release of the mandatory national standard for fuel consumption limits for passenger cars (gb19578-2021). Among them, "before 2025, the test conditions of traditional energy passenger vehicles and plug-in hybrid passenger vehicles will be switched from NEDC to wltc". Compared with NEDC, wltc has higher specifications, more complex test methods, and is closer to the actual driving fuel consumption and mileage. Relevant departments should promote wltc working condition test as soon as possible and include pure electric new energy vehicles, so as to provide consumers with more objective mileage data. The majority of automobile enterprises should also realize that the huge gap between "rational endurance" and actual use will virtually aggravate consumers' "mileage anxiety", lose trust in manufacturers' publicity and lose confidence in new energy vehicles, which is not conducive to the long-term development of the industry. On the one hand, new energy vehicle manufacturers should improve their publicity methods and clearly inform consumers about the mileage; At the same time, it is advisable to cooperate with third-party institutions to conduct actual road tests under different road conditions, different seasons and different driving situations, and publish relevant data for consumers' reference. Although these data are not as good-looking as "rational endurance", they are more referential to consumers. (outlook new era)
