The new energy vehicle industry is in urgent need of quality improvement

　　Miao Wei, Minister of the Ministry of Industry and Information Technology, recently stated that "the total investment in the entire industry chain of new energy vehicles exceeds two trillion yuan." Wang Chuanfu, chairman and president of BYD Co., Ltd., also commented on the current new energy vehicle market as "rapid development, exceeding expectations."

　　The market is bullish, citizens are enthusiastic about consumption, and the new energy vehicle market is booming. However, a social survey conducted by Sina.com in the first quarter of this year showed that nearly 70% of car owners regretted purchasing new energy vehicles.

　　The latest survey of new energy vehicle owners shows that cruising range and vehicle quality are still the biggest "pitfalls" of new energy vehicles. Nearly 70% of car owners said they regretted purchasing new energy vehicles, and more than 64% of car owners said they would not recommend new energy vehicles to their friends. For potential car owners, not being affected by the last-number driving restriction policy has become the biggest motivation for their purchases, accounting for 50%.

　　"From 2015 to 2018, the number of complaints about new energy vehicles in my country continued to rise, and more than 70% were quality complaints. Among them, battery complaints accounted for 64% and motor complaints accounted for 18%." Li Yang, Executive Secretary of the National Big Data Alliance for New Energy Vehicles This was stated at the framework conference of the "China New Energy Vehicle Evaluation Procedure System" held in February this year.

　　Corresponding to the increasing number of complaints, there are continuous occurrences of spontaneous combustion accidents of new energy vehicles. Statistics from the Shenzhen New Energy Vehicle Application and Promotion Center show that as of September 2018, there were eight spontaneous combustion accidents of new energy logistics vehicles in Shenzhen last year. In addition, the Shenzhen New Energy Vehicle Application and Promotion Center also stated in the "Emergency Notice on Strengthening the Operation Safety of New Energy Pure Electric Trucks" issued on March 17 that "many new energy pure electric truck charging incidents have occurred in Shenzhen recently" and battery thermal runaway accidents during operation."

　　In terms of new energy vehicle recall data, according to data released by the State Administration for Market Regulation, a total of 7 manufacturing companies were urged to recall 121,400 defective vehicles involving 33 models in 2018; the causes of defects were mainly electronic controls, machinery, electrical appliances and Battery system failure.

　　While complaints are increasing, subsidies are declining. According to the plan, new energy vehicle subsidies will be completely phased out by the end of 2020. In 2019, the subsidy policy was significantly reduced, and the sales growth of new energy vehicles slowed down in 2019. As the country relaxes the policy of foreign investment entering my country's new energy vehicle market, many people in the industry have pessimistic about the development of new energy vehicles.

　　Government and enterprises work together to tackle quality problems

　　Although new energy vehicles currently have many technical bottlenecks, they also face many market challenges. From the perspective of ownership, the number of new energy vehicles in 2018 reached 2.61 million, accounting for 1.09% of the total number of vehicles. From a statistical perspective, the number of new energy vehicles has increased by an average of 500,000 units per year in the past five years, showing an accelerating growth trend. According to statistics from Sina.com, 38.1% of consumers choose to buy new energy vehicles mainly because they consider environmental issues. Strong market demand for new energy vehicles still exists.

　　In addition, my country's new energy vehicles are in a favorable development atmosphere, both in terms of policy and technology, and it is more likely that the overall quality and after-sales service experience of new energy vehicles will improve rapidly.

　　In terms of policies, in addition to loosening purchase restrictions, local governments have introduced many policies on defective vehicle recalls, charging pile infrastructure, standardized charging training, and industrial quality development to provide policies for the development of new energy vehicles and related post-purchase services. Assure. Take Shenzhen as an example. On April 26 this year, Shenzhen held the 6th New Energy Vehicle Electronic Control and BMS Technology Seminar, which focused on new energy vehicle active and passive safety technology, new energy vehicle electric drive technology solutions, and new energy vehicle BMS safety. In-depth exchanges were held on a number of topics. In 2018, the Shenzhen Municipal Transportation Commission, Development and Reform Commission, and Planning and Land Commission jointly issued the "Notice on Accelerating the Construction of Taxi Fast Charging Piles and Supporting Facilities in Our City", requiring the city to complete the work in 2018 Construction of 13,400 sets of logistics charging piles. At present, Shenzhen has completed the construction of the world's largest fast charging station, covering an area of 20,000 square meters. It not only effectively alleviates the problem of "difficulty charging", but also explores a replicable development path for perfect charging stations across the country.

　　In terms of technology, new energy vehicle production and R&D companies have also increased research and development efforts to accelerate the improvement of the overall quality of new energy vehicles. For example, BYD has deployed multiple R&D centers around the world. Its global R&D center will be unveiled at its Shenzhen headquarters at the end of June, and its Changzhou R&D center is also under planning and construction. In terms of cruising range, BYD's new energy vehicles currently have a cruising range of more than 300km, which is at the world's first-class level, and their cruising capabilities are still improving. At present, my country ranks third in the world in the number of new energy vehicle patent applications, and the level of power battery R&D and manufacturing has been greatly improved. Some domestic power batteries have certain international market competitiveness in terms of energy density, cycle life, safety performance, etc., and the market The drive to improve technology is increasingly evident.

　　Ma Zhenshan, deputy general manager of FAW-Volkswagen Sales Co., Ltd., said at the "2019 China Automobile Chongqing Forum" held on June 4, "New energy vehicles are a process of reshaping the industry chain. It took decades for gasoline vehicles to be built. , Therefore, the era of new energy smart cars will also take 5 to 10 years to take shape. In this field, we must be prepared for a protracted war."
