Report: Battery life and charging are still the biggest concerns of new energy car owners

People's Daily Beijing, December 14 (Reporter Che Kemeng) Data released by the China Association of Automobile Manufacturers a few days ago showed that from January to November this year, the production and sales of new energy vehicles reached 3.023 million and 2.99 million units, respectively, an increase of 1.7 times year-on-year.

At present, the market penetration rate of new energy vehicles continues to reach a new high, but the endurance, charging and safety issues still affect their consumer confidence to some extent. Recently, the data agency J.D. Power (Jundi) and Zhichedi jointly released a winter new energy vehicle user survey report showing that both new energy vehicle owners and potential buyers have expressed great concerns about winter battery life.

The actual mileage is lower than the official data, which is the main cause of endurance anxiety. A total of 4330 valid samples were collected in this survey, and nearly half of the owners have never driven the official mileage, especially in winter, the endurance 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".

At the same time, 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 about the easy misoperation of the single-pedal mode: "The driver in the single-pedal mode is not familiar with the braking method, and it is easy to use the kinetic energy recovery as a brake, which causes misoperation in an emergency." ”

Pei Lin, director of automotive digital user experience in J.D. 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 endurance and charging, especially the battery is not antifreeze caused by the shrinkage of the battery 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.
