As the earliest domestic heavy truck manufacturer to obtain new energy vehicle production and product access, Shaanxi Auto has been trying to gain new growth points in order to win the initiative in the low-carbon economy and continuously increase the research and development of new energy vehicles.
At the communication and coordination meeting of the National Mobility Sector 2012 863 Plan Concise Project Framework held recently, Shaanxi Automobile Group Corporation applied for an item increase program for the evaluation of the development and storage of pure electric heavy commercial vehicles by 80.9 points, which is in the key technical topics of leading-edge technology vehicles. Ranked No. 7 and received state allocation of 9 million yuan. 
This is in September 2006, Shaanxi Automobile LNG heavy-duty truck development project was nominated for the 11th Five-Year National 863 High-Tech Research Project, which won a state grant of 1.73 million yuan. After the acceptance in 2010, it was re-entered the 863 program.
This is not only the full recognition of Shaanxi's new energy auto R&D projects by Shaanxi, it is also more conducive to the strategic development of Shaanxi Auto and the formation of new growth points as soon as possible.
The SX4186ZG331N heavy-duty pure electric tractor independently developed by Shaanxi Auto had been awarded the National Key New Product Plan for 2010 by the Ministry of Science and Technology. This is Shaanxi Automobile's first model to be awarded a national-level key new product in the field of new energy automotive products. The car was developed for the first time at home and abroad, filling the gap in the field of heavy-duty vehicles for new energy electric vehicle products in China, realizing the application of pure electric technology in heavy-duty tractors, and adjusting the industrial structure of China's automobile industry, especially heavy-duty trucks. And technological progress in the industry has played a huge role in promoting and leading role.
This heavy-duty pure electric tractor adopts the pure electric technology route. Its innovation is reflected in the following technologies: 1 vehicle layout and vehicle control technology; 2 load-carrying body and torsion-proof frame technology; 3 high-power motors and their control Technology; 4 super capacitor power supply system matching and application; 5 electric steering, braking, air conditioning system in the field of heavy truck matching and application; 6 heavy truck vehicle insulation technology. 
The super capacitor power system matching technology and high-power motor and its control technology used in this model are developed independently domestically. Other key technologies such as vehicle matching and control technology are independently developed by Shaanxi Steam. This heavy-duty pure electric tractor has won eight national patent technologies and applied for a national standard, which is the first time in the heavy truck industry.
Shaanxi Auto's heavy-duty pure electric tractors have the advantages of large starting torque, high speed accuracy, high system efficiency, easy maintenance, low operating cost, good environmental protection, and obvious energy saving effects. Tests show that compared with the traditional heavy-duty tractor, the standard coal energy consumed by the product is about 1/3 of the fuel vehicle, and the operating economic cost is saved by nearly half, and the energy-saving effect is significant. It has obvious advantages in the transport of goods from port yards with short transportation distances, fixed operating ranges, low-speed heavy-duty, and continuous working characteristics. It is of great significance for the establishment of conservation-friendly green ports and has a strong market in the cargo transport tools of port yards. Competitiveness. It is believed that the continuous development and application of new energy heavy trucks, especially pure electric heavy trucks, will set off a new round of storms in the heavy truck market.
