Hybrid, the most important new technology battlefield in the next 5 years! Although pure electrification is likely to be the main energy structure in the next few decades, it is still a long way to go in terms of infrastructure construction, battery technology and material physics at this stage, which cannot immediately meet the needs of all Chinese car users.
Hybrid power, on the other hand, not only meets the requirements of the dual-carbon strategy for energy conservation and emission reduction, but also meets the technical indicators of the whole scenario use of basic users. Like Changan, Great Wall, Geely, and GAC have launched powerful hybrid models, EXEED Xingtu as a high-end brand of Chery will certainly not be absent, so there is a star core power ET-i full engine supermix technology.
The power system of "Star Core Power ET-i Full Engine Super Hybrid" is made up of the "Strongest China Core" fuel engine with the full-featured DHT transmission as the basic hardware, which can realize the full-scenario technical advantages of "3 Engines, 3 Gears, 9 Modes and 11 Speeds". The total power of the two-wheel drive version reaches 240kW, the maximum wheel torque exceeds 4000N.m, and the acceleration of 100 km/h is less than 7s; the total power of the four-wheel drive version is 338 kW, the maximum wheel torque exceeds 6300N.m, and the 100 km/h acceleration enters the 4s level.
Here can be said 3 engines, the first engine is a 1.5T hybrid special engine, its performance indicators are 115kW maximum power and 230N .m peak torque. In addition to this 1.5T engine, Xingtu's hybrid-specific engine also includes 2.0TGDI, which is more powerful and suitable for models with higher power requirements.
The other 2 engines of the 3 engines are hidden in the DHT transmission, which are 2 motors of 55kW /160N .m and 70kW /155N .m, and the two motors of the Star Core Power ET-i Full Engine Supermix can be directly involved in the drive. Motor ultra-high density I-PIN flat wire motor technology allows more coil turns under the same volume, realizes the motor volume is smaller, the efficient interval is moved forward, the torque / weight ratio is higher than the predetermined goal, combined with the tooth surface two-way processing, low tow clutch, efficient oil pump, main oil pressure following strategy and other technical measures, so that the maximum transmission efficiency of the system exceeds 97.6%, reaching the same level of Japanese products.
"3 gears" refers to the "Star Core Power ET-i Full Engine Super hybrid" power architecture with the most 3 physical gears in the existing hybrid technology, and more gears also determine that the system can cope with more working conditions, higher efficiency, and can optimally balance power and fuel consumption.
"9 mode" is the abbreviation of the 9 working modes unique to the "Star Core Power ET-i Full Engine Supermix" system. Including single motor pure electric, dual motor pure electric, engine direct drive, parallel drive, parking charging, driving charging and other 9 driving modes. Under the control of the intelligent system, they can freely switch according to different driving scenarios, and match different road conditions with the most suitable and efficient mode. More driving modes naturally have a wider range of adaptation, which is also a strong generation difference advantage of the second generation hybrid system compared with the first generation of hybrid systems.
The "11 speed" here refers to the comprehensive analysis of tens of thousands of data measured by Xingtu Automotive engineers, from which 11 gear combinations can cover all car scenes, covering almost all driving scenarios, and can achieve a perfect balance between power and energy consumption. For example, in the initial stage, this is the stage with the lowest thermal efficiency and the largest energy consumption of the internal combustion engine, so in this stage, we set up a dual-motor pure electric drive. It can not only maintain the economical energy consumption of the vehicle, but also change the inherent perception of the soft start of the hybrid model with the powerful torque generated by the industry's unique dual motor drive.
When the low to medium speed does not require a large torque, the system automatically selects one of the single motors to drive, and our energy consumption is lower than in the start-up stage. On the elevated or ring highway, overtaking in the middle and high-speed sections is essential, and we know that the less time it takes to overtake, the safer it is, and this is when the 3 engines are on the battlefield and output 510NM of torque comparable to a six-cylinder gasoline engine.
"9 mode 11 speed" makes the fuel saving rate of the "Star Core Power ET-i Full Engine Super Hybrid" system is also the world's leading level, and the fuel saving rate of the low power mode > 50%. The fuel saving rate of urban working conditions >55%, and the fuel saving rate of high-speed working conditions > 35%.
Intelligent hybrid control system, so that the 3 engines always work in the best performance range, natural energy consumption is lower; the whole road condition adaptive power mode, the power control system and the navigation system dual core interconnection, in advance to identify the road conditions and intelligently realize the optimal power scheme; the use of CRBS energy recovery system. These high-tech allows Xingtu's new hybrid models to get rid of larger and heavier fuel tanks and batteries.
The result is an industry-leading >90% of the industry's average efficiency of the NEDC condition electric drive. At the same time, the fuel economy of the 1.5T hybrid special engine, intelligent dual motor torque distribution and intelligent hybrid control system, so that the "star core power ET-i full engine super hybrid" transmission efficiency of 97.6%, the comprehensive fuel consumption can reach 1L/100km, feed fuel consumption of 4.8L/100km.

Every Chery conference needs to be digested by the university science and engineering course, and the technical explanation of EXEED StarWay is read through and understood, and I think I can retake the doctoral examination..... As one of the key special projects of the 13th Five-Year Plan "National Key Research and Development Plan" "New Energy Vehicles", Star Core Power ET-i Full Engine Super hybrid will lay the foundation for the "3060" dual carbon target in China's transportation field.
