In the recently concluded
At the 2024 Beijing International Automobile Exhibition
Produced by NAC Jiangbei New District Base
New SUV model RWD D5X DMH unveiled
As the first SUV of the "D Family", the D5X DMH is equipped with the new 1.5T DMH super hybrid system, which is matched with the super hybrid-specific 1.5T engine, the DHT-2 hybrid-specific transmission, and the 21.4kWh super hybrid-specific long-range battery."The RWD D5X DMH has successfully challenged CACR's 'Extreme Safety Crash Test' three times, in addition to having the 'D Family's' standard Cloud Residence Intelligent Cockpit, which comprehensively upgrades the driving experience. " The relevant person in charge of NAC Group introduced.
NAC Jiangbei New District Base.
Automobile industry is a pillar industry in Nanjing. In recent years, Nanjing seizes the opportunity of new energy vehicle development, adheres to the direction of electrification, network connectivity, intelligent development, and accelerates to build a new energy vehicle industry cluster development highland.
As one of the important supports of the city's automobile industry, Jiangbei New District has formed a complete industrial chain from covering vehicle-grade chips, motors, batteries and other key components manufacturing, vehicle production and manufacturing, intelligent network system, vehicle-circuit coordination to terminal consumption.
Material innovation, technology upgrade
When evaluating whether a car is good or not, the key criterion is "whether the materials used are sufficient". Material is one of the key factors in determining the quality of a car in the manufacturing and assembly of the whole car.
One of the advantages for new energy vehicles is a smooth and quiet ride.Nanjing Jurong Technology Co.Relying on the self-developed "three-step" dynamic vulcanization technology, we have developed thermoplastic elastomer products such as motor soundproof cover materials for new energy vehicles and sealing materials for telecommunication equipments, so that new energy vehicles can be upgraded in terms of vibration damping, noise reduction and soundproofing.
"In addition to this, we have set up the 'Automotive Lightweight Composites Joint Innovation Laboratory' with SAIC Passenger Vehicle Center Laboratory and Donghua University to jointly promote the application of lightweight composites in automotive parts; and the 'SAIC Volkswagen -Nanjing Julong Joint Innovation Laboratory', to jointly strengthen the research and development and application cooperation in the fields of new materials, new technologies and new processes." Nanjing Julong staff introduced.
Focus on lithium batteries, overcome diaphragm difficulties
The energy efficiency of lithium batteries used in new energy vehicles is directly related to the range, service life, charging rate and safety of the vehicle. The four main materials of lithium battery - positive electrode, negative electrode, electrolyte and diaphragm, which together determine the performance and cost of the battery.As the first domestic manufacturer to successfully develop diaphragm materials for lithium batteries, Yangzi Petrochemical produces ultra-high-molecular-quality polyethylene (UHMWPE) battery diaphragm materials, one of the diaphragm materials with the best overall performance in the domestic market at present.
YPC Research Institute started the research and development of polyethylene lithium-ion battery diaphragm material 10 years ago and successfully produced polyethylene YEV-4500 for lithium-ion battery diaphragm for the first time in 2017, and the performance of this product has reached the quality standard of imported products after analysis and testing.
This is the first successful development of polyethylene special material for lithium-ion battery diaphragm, which fills the domestic gaps and guarantees the safety of the domestic new energy vehicle battery material industry chain and supply chain.
With the domestic new energy vehicle industry getting red-hot day by day, YPC's product range is also being enriched and making breakthroughs in the market.Nowadays, the production and sales volume of YPC's polyethylene lithium battery diaphragm material has increased significantly. In the first quarter, the output of lithium battery diaphragm material increased by 1,47% year-on-year, and the sales volume increased by 1,83% year-on-year.
Automotive Chips for the Road
Run fast, but also run safe, run smart, so a smart and clever "brain" is essential, as the command center of new energy vehicles, automotive chip determines the upper limit of a car.
"Focusing on the automotive chip track, we have deepened our product layout, and our core team has successfully developed two new products, which have made new breakthroughs both in the functional performance of the products themselves and in the application scenarios." Introduced by the person in charge of Nanjing Yingruichuang Electronic Technology Co.These two new products are general-purpose sensing chips SNU511 and SNU101, which have the advantages of high precision, fast response speed, and a wide range of categories, and have passed the AEC-Q100 automotive standard certification, which can meet a variety of application scenarios.Not long ago, Inritron brought these two chips to the International Sensor and Application Technology Exhibition.
In this exhibition, the USI general-purpose sensing chip of Inritron has also received high attention. The chip is suitable for application scenarios such as vehicle air conditioning, brake booster, vacuum booster, light and rain sensing, etc., and has already entered the supply chain of many domestic and foreign vehicle manufacturers.
Jiangbei New Area, as one of the city's four new energy automobile industry base, is constantly improving the industrial layout, encouraging technological innovation, optimizing industrial support services, to "new" to promote, to "wisdom" to improve the quality of the new energy automobile development tide to consolidate the advantages, and continue to enhance the The core competitiveness of the company has been continuously improved.
