With the step-by-step clarity and refinement of national and local new energy policies, as well as the opening of new energy vehicle policies in cities such as Beijing and Shanghai, a number of new energy vehicles were also intensively released in 2015, truly entering the market, regardless of imported cars, the joint venture car or self-owned brand, more and more new energy vehicles are available for consumers to choose.

 

Nowadays, new energy vehicles that have appeared in China's market, including those already on the market or coming soon, are mainly pure electric vehicles, such as BYD e6, JAC iEV4, BAIC E150, SAIC Roewe E50, Qichen Chenfeng, Tengshi, BMW, ZINORO, BMW i3 and i8, and Tesla. In addition, there are also some plug-in hybrid vehicles, such as BYD Qin, Volvo S60L plug-in hybrid. Of course, there are more car companies planning to launch more new energy products for the Chinese market in the future.

 

Speed up strategic layout

 

No car company will be willing to be behind. Taking advantage of the new energy vehicle policy, all car companies are taking the lead in market development and occupying a more favorable competitive position.

 

Recently, Volkswagen launched a one-week electric car promotion campaign in the Chinese market, called “e-call”. During the press conference, Volkswagen China President Jochem Heizman said: "In the near future, Volkswagen will supply more than 20 new energy vehicles to Chinese car owners, from small cars to large SUVs, from plug-in hybrids to pure electric." As early as April this year, Volkswagen signed an agreement with its partners in China, FAW Group and SAIC, to jointly develop environmentally-friendly vehicles and new energy vehicles for the Chinese market, including fuel cells and plug-ins with SAIC cooperation in electric hybrid technology, and joint development and production of a new car with outstanding environmental performance.

 

In March 2015, Beijing New Energy Automobile Co., Ltd. was established and became the first joint-stock new energy automobile company in China. As a new development platform for the new energy automobile industry, the company's registered capital of 2 billion Yuan will create an integrated model of research, manufacturing and sales industry chain, and comprehensively help BAIC Group achieve new breakthroughs in industrialization and marketization of new energy vehicles. . This year, BAIC New Energy plans to sell 20,000 pure electric vehicles and build a dedicated new energy sales channel.

 

As Qin has been in a state of short supply, power battery has become the main bottleneck restricting the sales growth of BYD's new energy vehicles. BYD has built a new battery factory this year, with an annual production capacity of 6GWH. The first phase of its plant has been put into operation in September. In addition, BYD has also signed a strategic cooperation framework agreement with the Hebei Provincial Government. It has agreed to build a BYD Chengde new energy vehicle and parts production base project, and build Chengde into an important new energy vehicle R&D and production base. It is understood that BYD Chengde new energy vehicles and parts production base project plans a total investment of 2 billion Yuan, after the completion of the project, it is estimated that the annual output of 5,000 pure electric buses. In the process of project construction, BYD Co., Ltd. will gradually build a production line for electric parts, electric control and power batteries in Chengde City, continuously increase the proportion of local supporting facilities, and gradually form the largest R&D and production base of new energy vehicles in the North.

 

Technology accelerated breakthrough

 

At the same time as the policy is continuously introduced, the industry itself continues to make efforts in technical patents. According to Professor Minggao Ouyang of Tsinghua University, the current energy ratio of China's battery system is about 100 watt-hours per kilogram. It is expected to reach 200 watt-hours per kilometer next year, and it is expected to achieve 300 watt-hours per kilogram by 2020. It is also known that as one of the key inner components in battery technology, lithium battery separator technology has made important progress recently, which will effectively improve the safety performance of power batteries.

 

The situation of lithium iron phosphate in the domestic power battery field will be broken soon. It is understood that at the end of this year, Beiqi's second-generation E150EV will be equipped with a ternary lithium battery system, which has advantages in terms of battery life and price. The fifth-generation electric vehicle of the Jianghuai, which is expected to be listed at the end of this year, will also use a ternary lithium-ion battery. It will require 23 degrees for a full charge and a range of 200 kilometers, an increase of 40 kilometers.

 

The design does not start "old"

 

Many of the new energy models currently on sale have "prototype cars", which are the corresponding gasoline version models. Under the premise of not changing the appearance and size of the vehicle body, according to the new energy vehicle, only the power unit is changed and the core components such as generators and motors are installed, and the cost is relatively reduced. For example, the Beiqi E150EV model is based on the Beiqi E-series gasoline version; the BMW Novo 1E, a pure electric vehicle of BMW Brilliance, is a pure electric version of the “X1”; the JAC and Yuet iEV models are basically derived from the Heyue model. The latest iEV5 front face has been redesigned.

 

Of course, on the other hand, there are more and more new models. Xingchu Xiang, general manager of Jianghuai Automobile (click to view the latest person news), when introducing the fifth generation of electric vehicles in Jianghuai, pointed out that most of the current electric vehicle products in China are based on fuel car models. The fifth generation of Jianghuai electric vehicles is based on the new electric vehicle platform. The small 5-seater pure electric car is equipped with a special chassis for electric cars. In the future, Jianghuai Automobile will use this electric vehicle platform to build electric commercial vehicles and electric trucks. In addition, such as the Roewe E50, the design is directly derived from the E1 concept car, completely unable to find the shadow before SAIC Roewe. The BYD e6 combines the characteristics of SUVs and MPVs and is newly designed for new energy vehicles. The “future” of the BMWi3 design is also strong. As a brand new brand, Tengshi is based on the different genes of Daimler and BYD.

 

After-sales service urgent follow-up

 

Compared with the fuel vehicles that have been developed for many years, the number and coverage of new energy vehicles' service facilities is far behind. However, a comprehensive service system has been established for new energy vehicles that have been on the market, including pre-sales showrooms and staffing, and post-sales support, and are constantly improving.

 

In the early stage of promotion, the manufacturers also provided a considerable supporting service for new energy vehicles. It is reported that most of the pure electric vehicles currently on the market will be free to give consumers charging piles and provide installation services. In terms of after-sales maintenance, BYD e6's three-package is valid for 2 years or 50,000 kilometers, and the battery provides lifetime warranty service; the whole vehicle warranty period is 6 years or 150,000 kilometers, and the manufacturer is within 6 years or 150,000 kilometers. The power battery provides a warranty and replaces the module when quality problems occur. The manufacturer also gave 4 free maintenances.

 

For the Beiqi E150EV, Beiqi New Energy also provides free maintenance of 50,000-100,000 km for the three core components of the motor, battery and electronic control system. In addition, Beiqi New Energy also provided a 24-hour “Zhihui Butler” service within three years. Within 40 minutes after receiving the report, Beiqi New Energy Rescue Vehicle will arrive at the scene for rescue.

 

Tesla offers a four-year or 80,000-kilometer vehicle warranty and a battery pack warranty of eight or 160,000 kilometers for the ModelS currently sold in China.

 

Tengshi has set up 11 service centers and a 24-hour customer service hotline, and will team up with the well-known Allianz Global Rescue to provide 24-hour roadside assistance and customer hotline services. Tengshi also provides a three-year or 80,000-kilometer warranty over the three-pack standard for the entire vehicle, and a six-year or 150,000-kilometer warranty on the battery.
