On January 7, EXEED Xingtu Automobile released the "Star Core Power ET-i Full Engine Super hybrid" system, officially opening the field of new energy hybrid, which has the "strongest Chinese core" fuel engine with a full-featured DHT transmission, and realizes the industry-leading "3-speed, 3-speed, 9-mode 11-speed" technology core advantages.
According to reports, the E in "Star Core Power ET-i Full Engine Supermix" is taken from the initial letter of EXEED (starway name) + Electric (new energy strategy), T is taken from the initial letter of Technology (technology), and i is taken from the initial letter of Intelligent (intelligence), which represents the gene source, technical support and intelligent drive implied by the technology.
In the future, the first model of "Star Core Power ET-i Full Engine Super Mix" will be the first to be put on the Starway Wind Chasing ET-i, which will soon be sold, which will also herald the official landing of the hybrid technology of Starway Automobile. The standard version of the car can reach a pure electric driving range of 105km, and the comprehensive driving range exceeds 1000km.
The industry's first 3-engine, 3-speed, 9-mode, 11-speed
"Star Core Power ET-i Full Engine Super Mix" industry pioneered "3 Engine 3 Gear 9 Mode 11 Speed", behind the seemingly simple digital sequence, contains the industry's leading "black technology".
"3 engines" refers to the intelligent combination of internal combustion engine and dual drive motor under this power architecture. Among them, the "1 engine" is a 1.5T hybrid special engine, which can produce 115kW of power and a maximum torque of 230N .m, in addition to this 1.5T engine, the hybrid special engine of Xingtu also includes 1.5TGDI and 2.0TGDI, which are more efficient and have better power performance, suitable for models with higher power requirements.
The other "2 engines" are two motors integrated in the DHT cabinet that are 55kW /160N.m and 70kW /155N .m respectively. Compared with the existing hybrid technology, the dual motors that can participate in the drive and the specific power of up to 6.0 kW/kg are the outstanding capital of the "3 Engine". Among them, the ultra-high density I-PIN flat wire motor technology makes the number of coil turns under the same volume more, 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 towing clutch, high efficiency 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. The original FIO fixed-point injection oil cooling technology of Star Core Power adopts multi-point uniform injection + rotor oil-oil-cooling technology when the motor is running, which can effectively control the temperature rise of the motor and prolong the service life, after > 30,000 hours of bench verification accumulation, as well as > 5 million km vehicle verification accumulation, it is confirmed that the motor can reach 1.5 times the average service life of the industry.
"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.
"11 speed" 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 use scenarios, covering almost all driving scenarios that users may encounter, including extreme road conditions such as urban commuting and long-distance travel, but also achieving a perfect balance between power and energy consumption. This "11 speed" can be said to be the essence of the best of the best through the accumulation and analysis of big data. It is understood that the fuel saving rate of the "9-mode 11-speed" system makes the "Star Core Power ET-i Full Engine Supermix" system 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%.
From the perspective of demand, we will create 4 core value points
The progress of technology is to make everyone's life more convenient, more comfortable and more relaxed. The "Star Core Power ET-i All-Engine Super Hybrid" power architecture has "3 engines, 3 gears, 9 modes and 11 speeds" and is closely related to the interests of users, and the four core values of "strong power, ultra smooth, long endurance, and extreme fuel saving" are combined, creating a fish and bear paw can both get scientific and technological benefits.
From the beginning of the development of hybrid technology, energy saving is its core purpose. The power performance of hybrid models, especially the "strong power" in the high-speed range, has always been a luxury that cannot be combined. The "Star Core Power ET-i Full Engine Supermix" technology that has stepped into the hybrid 2.0 era, the total power of the two-wheel drive version reaches 240kW, the maximum wheel side torque exceeds 4000N.m, the acceleration of 100 kilometers is less than 7s, the total power of the four-wheel drive version is 338kW, the maximum wheel side torque exceeds 6300N.m, the 100 km acceleration enters the 4s level, the torque of the big six cylinder is opened, and the acceleration of the performance car becomes a matter of course.
Especially in the high-speed range, the power reserve and acceleration capability are particularly prominent, which is also a performance advantage with the generation difference with 1.0 technology. At the same time, with the blessing of TSD dual-shaft drive technology, there is no power interruption and power loss during the shifting process, and the driving smoothness feels "super smooth", comparable to pure electric models.
Returning to the housekeeping skills of hybrid models "long endurance" and "extremely fuel-efficient", the design of the "Star Core Power ET-i Full Engine Super hybrid" technology "blindly pursues high data and starts from the actual needs of users", which also fully reflects the more mature technical ideas in the 2.0 era.
Is it necessarily better to have a range of 2,000 kilometers than 1,000 kilometers? Or is it more scientific to design according to the actual daily needs of users? The intelligent hybrid control system adopted by "Star Core Power ET-i Full Engine Supermix" makes the 3 engines always work in the best performance range, and the natural energy consumption is lower; the full road condition adaptive power mode, the power control system and the navigation system are interconnected, the road condition is identified in advance and the optimal power scheme is intelligently realized; and the CRBS energy recovery system is adopted. The application of these high-tech technologies has allowed hybrid models to gradually get rid of the initial mode of increasing energy portability to improve data in the 2.0 era, and also let The new hybrid models of Xingtu Automobile get rid of larger and heavier fuel tanks and batteries. The average efficiency of the NEDC electric drive also achieves an industry-leading > of 90%.
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. Let the user's oil and electricity advantages be fully occupied, and the province can afford to use.
