Open a new chapter based on intelligence
Brand-new "JAC" logo for passenger cars of Jiang Qi Group.
In order to quickly respond to market trends and consumer demand, Jiang Qi Group reorganized its brand structure, which is different from commercial vehicles. Passenger cars appeared with a brand-new "JAC" image, adhering to the brand values of "leading intelligence with intelligence" and constantly strengthening the technological innovation of intelligent network.
Xia Fa, General Manager of Group New Energy Passenger Car Company, released the Yttrium brand.
In this regard, Jiang Qi Group also officially released the brand of new energy passenger cars-JAC YWEI, adopting a brand-new logo, which indicates that JAC passenger cars will open a new chapter. "Today, we released the new passenger car standard of Jiang Qi Group, and released the vision, mission and values of passenger cars, which is a concrete action for Jiang Qi Group to seize the development opportunity of intelligent new energy vehicles and practice high-quality development. It is a new declaration of Chinese smart cars, marking that Jiang Qi Group has entered a new era of' no intelligence, no car'. " Xiang Xingchu, Party Secretary, Chairman and General Manager of Jiang Qi Group Holding Company, said. It seems that Jiang Qi Group's passenger cars will be dominated by "JAC" in the future, and JAC Yttrium will become its first brand.
It is the first time to apply 46 series batteries, and the nine-in-one electric drive is highly integrated.
After 17 years of industrial technology accumulation, at the press conference, Jiang Qi Group launched the second-generation pure electric platform-DI platform, which can be described as a riveting enlargement.
Series 46 large cylindrical battery pack
Cellular battery technology with zero thermal diffusion
As for the battery, the monomer adopts 46 series large cylindrical battery, which is the first application of 46 series large cylindrical battery in China. It is reported that it is a 46950 battery, which adopts high-nickel ternary cathode material and full-lug design. Compared with the products of the same level, the battery life can be increased by nearly 30%, the internal resistance of the battery can be doubled, and the charging calorific value can be reduced by more than 40%. Coupled with the efficient and intelligent temperature control system of the battery, it can realize super flash charging, and the battery life is 10 minute, which is twice as high as that of ordinary fast charging. Combined with honeycomb battery technology, the thermal diffusion of 46 series batteries in different life stages, different failure modes and different failure locations is realized through triple protection of thermal isolation, electrical isolation and thermal electrolysis coupling.
Integrated design of CTB body battery
The battery pack adopts the integrated design of CTB body battery, and the capacity of the battery pack is effectively increased by 30%, making Jiang Qi the third vehicle enterprise in China to announce the adoption of CTB battery technology? . Although, like Tesla, the 46 series large cylindrical battery is used in the integrated design of the car body, according to the publicity materials, Jiang Qi integrates the upper cover of the battery pack with the bottom plate of the car body, which is different from the integration of the upper cover, the bottom plate of the car body and the seat beam of Tesla.
Nine in one power system
In terms of electric drive, the 9-in-1 powertrain was loaded for the first time, and the integration level reached a new high, realizing the integration of nine parts, namely motor, electric control, reducer, DC/DC, vehicle charger OBC, external DC/AC, high-voltage distribution box PDU, PTC controller and super flash charging. It is equivalent to adding PTC controller, external DC/AC and super flash charging module on the basis of the traditional six-in-one powertrain (that is, the integration of motor, electronic control, reducer, DC/DC, OBC and PDU). Among them, this super flash charging module is the most mysterious and one of the core highlights of the DI platform. More details need further official disclosure. The 9-in 1 powertrain is small in size and light in weight, with a transmission efficiency of 94%, a mass power density of 5.5kW/kg and a power range of 70- 150kW. In this way, the seating space becomes larger and passengers are more comfortable to sit on; The NVH performance of the nine-in-one powertrain is better, making the car quiet and driving experience better. Combined with the collision force transmission structure integrated with the body battery, the distance between the longitudinal beams of the electric drive cabin can be reduced, the wheel angle can be increased, the turning radius can be effectively reduced, and the vehicle turning is more convenient and flexible.
Global thermal management system
In addition, the DI platform also launched a global thermal management system based on the second generation of heat pump air conditioning, which makes cooling and heating faster and more energy-saving; At the same time, the intelligent entertainment cockpit was upgraded, and yttrium assisted the pilot intelligently. Intelligent driving of passenger cars focuses on L2, and commercial vehicles try to land on L4.
The first model of DI platform came out, pushing four new cars in five years.
Yttrium officially appeared as 3.
Sodium ion battery version yttrium is 3.
At the press conference, the first model of DI platform, Yttrium 3, was officially unveiled. It is reported that there are two versions of new car batteries, of which the lithium iron phosphate battery version is mainly provided by Guo Xuan Hi-Tech, and the ternary lithium battery version is mainly provided by Yiwei Lithium Energy, both of which adopt cellular battery technology. At present, the version of lithium ferrous phosphate has entered the 369 batch announcement catalogue of the Ministry of Industry and Information Technology. The new car redefines the pure electric A-class car, integrates DI platform technology, has more body space, can realize leapfrog enjoyment, has the smallest turning radius in the same class and has a better driving experience. It is expected to be launched in the second quarter. Interestingly, the exhibition area also showed a sodium ion battery version of yttrium 3. It is reported that it is a sodium ion battery jointly built by Jiang Qi Group and Zhongke Haina, and it is currently being loaded and verified.
In the next five years, Yttrium JAC will be used as a new energy pure electric A-class vehicle market, and four heavy products, Yttrium 3, Yttrium X3, Yttrium 5 and Yttrium X5, will be built to meet the demand of increasing purchase and first purchase respectively. Among them, Yttrium is an intelligent pure electric A-class SUV with X3 positioning, Yttrium is 5 and Yttrium is an intelligent pure electric coupe and SUV with X5 positioning. It has a long battery life of 800 kilometers and a super flash charge of 10 minutes, which effectively solves the problem of mileage anxiety. In the face of the most competitive and largest A-class car market, it remains to be seen whether JAC Yttrium, which has many technologies, can break into a world.
