On January 7, the "Star Core Power ET-i Full Engine Super Hybrid" technology was officially released, representing the official entry of EXEED Starway into the field of new energy hybrid. It is reported that this technology is one of the key special projects of the "13th Five-Year Plan" national key research and development plan "new energy vehicles", creating a new path for Chinese hybrids with complete intellectual property rights.
In the "Star Core Power ET-i Full Engine Super Hybrid" power architecture announced this time, the engine is equipped with a full-featured DHT transmission, which realizes the core advantages of the industry-leading "3 engine, 3 gear, 9 modes and 11 speed" technology. Combined with the intelligent control system and the power architecture composed of high-performance battery packs, its performance has realized the leap of China's hybrid technology from the 1.0 stage to the 2.0 stage.
The industry's first 3-engine, 3-speed, 9-mode, 11-speed
"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 engine, which can generate 115kW of power and a maximum torque of 230N .m, in addition to this 1.5T engine, Xingtu's hybrid engine also includes 1.5TGDI and 2.0TGDI.
The other "2 engines" are two motors integrated in the DHT box that are 55kW /160N.m and 70kW /155N .m. 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".
"3 gears" refers to the 3 physical gears with the most in the existing hybrid technology, and the more gears also determine that the system can cope with more working conditions, higher efficiency, and can optimally balance power and fuel consumption.
"9 modes" refers to the abbreviation of the unique 9 working modes. Including single motor pure electric, dual motor pure electric, engine direct drive, parallel drive, parking charging, driving charging and other 9 driving modes. They can switch freely 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 Auto engineers, from which 11 gear combinations can cover almost all car scenes, covering driving scenarios that users may encounter, including extreme road conditions for urban commuting and long-distance travel, but also achieving a 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 it is a dual-motor pure electric drive. When the low and medium speeds do not require large torque, the system will automatically select one of the single motors to drive, and to the elevated or ring highway, the overtaking of the middle and high speed range is indispensable, at this time, the 3 engines are on the battlefield, and the output is comparable to the 510N·m of a six-cylinder gasoline engine.
Technology allows fish and bear paws to be combined
The power architecture of "Star Core Power ET-i Full Engine Super Hybrid" combines the four core values of "strong power, ultra smoothness, long endurance and extreme fuel saving", creating a fish and bear paw that can both enjoy 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. And has stepped into the hybrid 2.0 era of "star core power ET-i full engine supermix" technology, the total power of the two-wheel drive version reaches 240kW, the maximum wheel 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 wheelside torque is more than 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. 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 hybrid model "long endurance" and "extremely fuel-efficient" housekeeping skills, the "Star Core Power ET-i full engine supermix" technology naturally has a good performance, 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. On the upcoming "Star Core Power ET-i Full Engine Super Hybrid" technology first model - StarWay Wind Chasing ET-i, the standard version can reach a pure electric driving range of 105km, and a comprehensive driving range of more than 1000km.
The national "black technology" aura is added
At the press conference in the name of "technological awakening", Dr. Wang Zhifu, secretary of the National Engineering Laboratory for Electric Vehicles, said: Hybrid projects due to the long research and development cycle, difficulty in the layout of the whole vehicle, the independent investment in research and development and promotion of enterprises is very difficult, so the national research on hybrid systems in the scientific and technological innovation research and development plans over the years is a key research topic.
As one of the key special projects of "New Energy Vehicles" of the "13th Five-Year Plan" National Key Research and Development Plan, the "Star Core Power ET-i Full Engine SuperMix" project has also achieved "the first DHT that can be driven by dual motors in China; THE DHT with the largest position of chinese brands; the integrated design of MCU and FCL, low cost, and can match multi-platform models" and many other advantages of independent intellectual property technology.
