Great Wall Commercial Vehicle Joins Hands with China Auto Research Institute to Explore Lightweight Technology Innovation of New Energy Commercial Vehicle

Recently，By China Auto Research（China Automotive Engineering Research Institute Company Limited）Organized“Seminar on R & D and Application Technology of Microalloyed High Performance Automotive Steel”Held in Chongqing，Great Wall Commercial Vehicle attended the event as a representative of new energy commercial Vehicle enterprises.，It shared the innovative achievements of its new generation of Great Wall Smart Card in collision safety and lightweight.。

This seminar，It is based on the early stage of Great Wall Commercial Vehicle and China Auto Research Institute.《Development of High Strength and Lightweight Commercial Vehicle Battery Frame》On the basis of cooperative projects，Another important measure to further deepen cooperation。Great Wall Commercial Vehicle has been committed to providing users with new energy commercial vehicle products with international competitiveness.。Relying on the strong support of the forest ecological system of Great Wall Automobile，Its brand-new Great Wall Smart Card has realized many innovative technology applications.。

Especially in collision safety and lightweight technology applications.，Great Wall Smart Card uses a large number of high-strength niobium alloy steel materials and 1500MPaRade high performance hot forming steel。With the Great Wall Smart CardEVVehicle power battery integration framework as an example，It is a double-layer combined structure made of high-strength niobium alloy steel.，Bearing ratio up to 5.5，And has higher bending and torsional stiffness.，It can effectively meet the lightweight and safety requirements of power battery system.，Performance is at the advanced level in the industry。

In addition，Great Wall Smart Card not only uses a large number of high-strength steel materials in the cage body, but also uses a large number of high-strength steel materials.，Moreover, technical improvements and innovations have been made in vehicle protection.。Among，In terms of material technology, the front lower protective assembly adopts 1500 for the first time.MPaRade high performance hot forming steel，In terms of structural technology, transverse reinforcement is added to the stress surface of the front lower protective beam.，It is used to improve the rigidity of the front lower protective beam.，And integrate structures such as a step support and that like.，Simplify design to reduce weight，High quality to achieve lightweight and safety goals of body and protection system。

Through this seminar，Great Wall Commercial Vehicle and China Auto Research and other industry organizations have discussed in depth the development direction of lightweight technology for new energy commercial vehicles.，And looked forward to the future prospects for cooperation.。Research and development of common key technologies of China Auto Research Institute、Deep strength and rich experience in the field of testing and standard certification，It will play a vital role in the follow-up cooperation between the two sides.。Future，Great Wall Commercial Vehicle will join hands with China Auto Research Institute，Constantly explore new technologies、New ideas，Strive to be intelligent in commercial vehicles、Take the lead in the tide of electrification，Jointly promote the development of China's automobile industry，Continue to contribute to the prosperity and progress of the industry。
