In the field of new energy vehicles, Dongfeng Motor Company is not a high profile company.
However, the Dongfeng Motor (600006) company's new energy sedan recently entered the harvest season. On June 10, the Dongfeng Fengshen New Energy Sedan E30 officially began mass production. In order to publicize and promote this new energy sedan, the E30 was the main trolley type of Dongfeng Motor Company at the 2013 Wuhan International Auto Show and the 2014 Beijing International Auto Show. In the words of Huang Zhaoqin, Director of Dongfeng Motor’s New Energy Vehicle Business Platform, it is said that “the spread of sound is to have a purpose. It is necessary for consumers to understand brands and products and help market developmentâ€.
Different from Dongfeng Motor Company, some domestic automobile enterprises are very high-profile. Even if the products have not yet been developed, new energy vehicles are made up and refitted, and they are also vigorously publicized. The starting point is to make consumers more easily accept new energy vehicles, but often It was a high-profile appearance but it was still weak. According to industry sources, the purpose of propaganda for car companies is to make the company's share price perform better.
In fact, Dongfeng Motor Company began to develop new energy automotive technology in 1997, mainly pure-electric minibuses, fuel cell minibuses, and pure electric cars. Huang Zhaoqin told reporters.
After the establishment of a new energy auto business platform in 2010, Dongfeng Motor Corporation has entered the "fast track" for the comprehensive promotion of new energy vehicles. The entire company's new energy vehicle project has been integrated into the platform for unified and coordinated management. Subsequently, Dongfeng Motor Company announced that it will invest 3 billion yuan in the "12th Five-Year Plan" period for the development of new energy vehicles.
Accumulation
Dongfeng Motor Company entered the field of new energy vehicles very early.
During the "Ninth Five-Year Plan" period, Miao Wei, the then general manager of Dongfeng Motor Corporation, was named Xu Guanhua, Minister of Science and Technology, to discuss his thoughts on electric vehicles. Miao Wei’s plan was supported by Xu Guanhua: “If you can, I will support you on behalf of the Ministry of Science and Technology.â€
do as promised. In 2001, Miao Wei co-formed Dongfeng Electric Vehicle Co., Ltd. with Wuhan, Hubei Province, Wuhan Development Zone, Wuhan University, Huazhong Institute of Technology, and Wuhan University of Technology. This year, Miao Wei took over as general manager of Dongfeng Motor Company for the third year. He led Dongfeng Motor Co., Ltd. to achieve profitability, with a profit of 1.38 billion yuan in 2000. At that time, Dongfeng Motor Corporation was headquartered in Shiyan City, Hubei Province. This is an industrial city that is more than 400 kilometers away from Wuhan and is buried deep in the Qinba Mountains. However, electric vehicle companies have settled in Wuhan directly.
Who is responsible for the day-to-day work of this company? Miao Wei decided to openly recruit the general manager of the electric vehicle company within the company. After a written test, an interview, and finally a TV reply. At that time, Dongfeng Motor Company had its own closed-circuit television, on-site and off-site interaction during the television reply, and each contestant had to go up and talk for half an hour. Then he accepted questions from all employees and several shareholders took aside to score. Finally, Huang Zhaoqin, who graduated from Tsinghua University, served as the first general manager.
Of the seven shareholders, although Dongfeng Motor Co. only accounts for more than 30% of the shares, Miao Miao is determined to do a good job of electric vehicles. He said with Xu Guanhua: “With new mechanisms and new systems for R&D and industrialization, we must mobilize the enthusiasm of all R&D personnel and use our valuable funds to spend every penny on R&D.â€
Crouching
It takes 3 to 5 years from the development to the launch of a new model. Dongfeng Motor Co. does not want to fight for an electric car on the market. At the end of 2011, Dongfeng Fengshen E30 project was handed over to the company’s deputy chief engineer Wang Yunzhong.
The team responsible for the development of the E30 project has 50 to 60 members. Li Rui is an engineer in the Product Development Department of the Technology Center. In an interview with reporters, he said: "As a new model, before the development, we must not only consider the overall design of the car itself, but also consider if the concept is turned into a product after the market, the degree of acceptance and necessity of users. This includes models. Dimensions, powertrain parameters, body comfort design, vehicle selling points, etc., must all be determined through rigorous evaluation."
Qin Xinwu, the head of the technical department of the technical center, described to reporters that the E30 R&D process includes seven links. As the person in charge of vehicle body design, he also has to continuously communicate with Li Rui’s vehicle design and project management. Every R&D has to do a lot of work. Because the frame was changed from steel to aluminum, the powertrain was changed from a conventional engine to an electric motor, and the fuel was changed from gasoline to high voltage. Li Rui believes that most people are concerned about the electric car is safety, so "how to make the body The fact that the framework meets the requirements for collision safety while ensuring the insulation safety requirements of high-voltage electricity is a top priority.â€
In order to meet the national requirements for collision regulations, the first collision test was conducted in 2012. Qin Xinwu recalled: “After our first round of experiments, the deformation of the door frame exceeded the requirements.†As the Dongfeng Motor Company EJ project is the first body in China to use all aluminum alloy materials at the same time, domestic aluminum alloy material manufacturing and molding The level of technology is still far behind that of foreign countries. The fluctuation of raw material properties and the influence of aluminum alloy forming and welding on the overall strength of the car body have become the main factors of this loss.
Therefore, through repeated testing of aluminum alloy raw material production and molding process, they ensure that the aluminum alloy material achieves a stable performance range, and the formed parts also meet the performance requirements of the structure, and finally passed the verification of regulations.
Debut
4 years of hard work, finally harvested.
On April 20, 2014, in the Dongfeng Motor Company Pavilion at the Beijing International Auto Show, Liu Weidong, deputy general manager of Dongfeng Motor Co., which was in charge of the new energy vehicle, delivered the keys to the first batch of 30 auto customers of the Dongfeng Fengshen E30.
From a distance, the Dongfeng Fengshen E30 is born with a lovely appearance, which is in line with the theme of the “Moe†nowadays. The two-door design and the compact body are conducive to smooth traffic in urban traffic. The multiple choices of two seats and four seats can satisfy more personalized demands.
In close view, Dongfeng Fengshen E30 matched 25kW permanent magnet DC motor and 18kWh lithium iron phosphate battery pack to provide power and energy reserve for the vehicle. The maximum speed can reach 80km/h and the cruising range can reach 160km. Charging, slow charge to 7 hours, fast charge half an hour to complete.
This is a brand new electric car. Liu Weidong, who is standing on the stage of the Dongfeng Pavilion, said: “Dongfeng Fengshen E30 pure electric car is a brand new platform pure electric car that integrates many new materials, new technologies and new technologies. It is the latest research independently developed by Dongfeng Company over 4 years. The results are also the most important strategic models for Dongfeng’s new energy vehicles '12th Five-Year Plan'.â€
In order to make the E30 vehicle lighter and make the battery more fully used, its frame uses an all-aluminum product rather than a conventional steel frame. Huang Zhaoqin introduced that the quality of the four-seat E30L vehicle is only 1025 kg, and that of the two-seat E30 is only 920 kg. The lightest conventional steel body car also has 1.1 tons, even up to 2 tons.
Liu Weidong is very proud of this model: “Over the years, from key components to complete vehicles, from hybrid to pure electric vehicles, the company has mastered core technologies in multiple fields, accumulated experience, and has done a good job Preparation for the industrialization of models."
The E30 is the most important model of Dongfeng New Energy Vehicle. However, the performance of the entire Dongfeng New Energy Vehicle made Liu Weidong happy. Dongfeng Motor has acquired more than 40 new energy vehicles in the national announcement and has already demonstrated the operation of new energy vehicles in cities such as Wuhan, Shenyang, Guangzhou, Zhengzhou and Dalian. In delivering the E30 key to customers, he also said: "In the future, Dongfeng Motor Corporation will continue to focus on pure-electric vehicles as a medium- and long-term strategic focus, autonomously mastering core assembly technologies and resources, innovating business models, and accelerating the promotion of Dongfeng New Energy Vehicles. development of."
