Original title: Index | winter survey of new energy vehicles found that the temperature is lower than 10 degrees, and endurance and battery problems begin to appear concentrated
Sales record high endurance is still a short board, nearly half of the new energy owners said that they have never driven to the official notification mileage
The market penetration rate of new energy vehicles continues to reach new highs, but battery life, charging and safety issues are still important factors affecting their consumer confidence. Recently, the authoritative data agency J.D. Power (Jundi) and Zhichedi jointly released a winter new energy vehicle user survey report, whether it is a new energy vehicle owner or a potential buyer, they have expressed great concerns about winter battery life. A total of 4330 valid samples were collected in this survey, and nearly 50% of the respondents believed that the endurance attenuation was acceptable at low temperatures by up to 10%.
2021 is coming to an end, from the first 11 months of data, China's new energy vehicle sales are close to 3 million, the market has entered a stage of explosive growth. Compared with the hot market, the winter use anxiety of new energy vehicle users is still widespread, and this survey focuses on the winter car concerns of Chinese new energy vehicle owners and potential customers. The data shows that the actual driving range is lower than the official data is the main cause of endurance anxiety, nearly half of the owners have never driven to the official mileage, especially in winter, the mileage is greatly affected by temperature.
The report pointed out that when the temperature is lower than 10 °C, the endurance and battery problems of new energy vehicles begin to appear in a concentrated manner, and the vehicle starting power is insufficient, the remaining mileage suddenly drops, and the charging becomes slower. In addition, air conditioning is the main "killer" of winter battery life, and most people believe that warm air cannot maintain the ideal temperature in low temperatures.
In the survey, users generally said that the first 5 to 10 kilometers of cold car start driving, the power is less than 50%, and the subsequent voyage decline is significantly accelerated. In the case of a sudden drop in power, it is necessary to charge in advance to avoid anxiety. When charging, -9 °C ~ 10 °C is the most common scenario affecting the charging speed, even if there is fast charging, 41% of car owners also think that "not fast".
The braking ability of the brake is also a problem that users are more concerned about in winter. Some new energy vehicle owners expressed concern that the single-pedal mode is easy to misoperate. "Drivers in single-pedal mode are not familiar with braking methods, and it is easy to use kinetic energy recovery as brakes, causing misoperation in emergency situations."
J.D． Pei Lin, director of automotive digital user experience at Power (Jundi) China, said that whether it is a new energy car owner or a potential car buyer, the primary concern for new energy vehicles is still focused on battery life and charging, especially the battery life shrinkage caused by non-freeze resistance needs to cause industry vigilance. In the next few years, technological progress and iteration in batteries will continue to be the focus of the automotive industry, especially to enhance the vehicle endurance in the common winter temperature (-10 °C to 10 °C) scenario. Major car companies need to take the actual experience of consumers as the basis to enhance the "adaptability" of new energy vehicles in different scenarios, thereby promoting the better development of the entire industry.
At present, China's new energy vehicles generally adopt the NEDC (new standard European cycle test) working condition endurance standard, because the driving habits, on-board electrical appliances, kinetic energy recovery and other actual conditions are not considered, the endurance shrinkage is more common. Many respondents also suggested that there should be more objective actual endurance tests to provide users with references for use in different scenarios and increase the true understanding of new energy vehicles of various brands.
