Chedong march 17 news, "breaking the situation double carbon" 2022 vehicle power system international summit forum held today, a number of experts jointly discussed the dual carbon target of China's vehicle energy structure and development direction, and carried out the carbon neutral vision of energy reform and internal combustion engine fuel development and other keynote speeches.
Among them, Li Xiaozhe, vice president of Zhejiang Geely Powertrain Research Institute, conducted the "Geely Lei Divine Intelligence Qing Hi · X Hybrid System Brief Analysis" shared, according to him, Gilly Lei Divine Intelligence Hi · X hybrid system engine thermal efficiency of up to 43.32%, higher than other competitors, but also the world's first 3-speed hybrid electric drive transmission DHT Pro, can achieve 3-speed speed increase torque function, in the 4 working modes of free switching, while ensuring low-noise driving of the car.
In addition, it is equipped with the Thor God Spirit Hi · X hybrid system Geely Star Yue L Thor Hi · X once ran 1426.1km with a tank of fuel in the race, exceeding the 1300km marked by the official website, and has opened reservations today.
First, 5 platform advantages 6 major hybrid technology 3 gear variable speed 4 working modes
As a modular intelligent hybrid platform, RayTheos Hi· In addition to the five platforms of global high-end power platform, expandable hardware space design, expandable electrification drive platform and evolvable power platform, X also has six major hybrid technologies.
These six major hybrid technologies are the 43.32% engine thermal efficiency, 3-speed DHT Pro, hybrid system FOTA upgrade and up to 20 intelligent driving modes, full hybrid systems that can be matched with different models of A0-C class and adapted to heV/PHEV/REEV, and 148 key NVH technology optimizations.
Li Xiaozhe, vice president of Zhejiang Geely Powertrain Research Institute, introduced that based on the four advanced technologies of supercharged intercooling, high-pressure direct injection, Miller cycle and low-pressure EGR, Geely's 1.5TD hybrid special engine achieved a thermal efficiency of 43.32%, setting a record for the highest thermal efficiency of the world's mass-produced hybrid engine.
In addition, Thor's Mind Ishi · X hybrid system adopts the world's first 3-speed hybrid electric drive transmission DHT Pro, which integrates 1 power generation motor and 1 drive motor, 2 motor controllers and 3-speed ratio variable speed increasing torque mechanism, which can realize pure electric drive, oil-electric hybrid drive, intelligent power generation, intelligent energy distribution four working mode switching and 3-speed variable speed torque increase function, the maximum output torque of up to 4920N·m.

It is understood that Ray's mind is in the air. The X hybrid system is also compatible with Geely's intelligent electrical and electronic architecture GEEA 2.0, which can be upgraded and updated by FOTA, and it is also the first hybrid system that can achieve FOTA upgrade.
With the help of intelligent architecture, Hi· X will be able to identify the driver's driving habits, road congestion, to achieve driving mode adaptation, self-learning and self-adjustment and other 20 intelligent working modes, to bring users a smarter and more efficient driving experience, making driving easier.
In order to meet the needs of different consumers for intelligent hybridization, Ray God Intelligence Qing Hi · The X hybrid system can be matched with different models of A0-C class, and is suitable for full hybrid systems such as HEV/PHEV/REEV. In addition, in order to improve the riding experience and reduce the noise in the car, the developers have also optimized 148 points related to the power of the system.
With the help of these five platforms and six major hybrid technologies, Ray's Mind Qing Hi · The X Hybrid System drives through intelligent energy management, calculating the most economical mode, making driving more fuel-efficient, powerful, smarter and more comfortable.
In addition, Thor's Mind Ishi · X's system highlight also includes full-speed domain parallel mode. At a speed of more than 20km per hour, the system can enter the parallel mode, when starting, the 3-gear DHT Pro through the clutch sliding, matching the 1st gear large speed ratio, to achieve ejection start, 80 ~ 120km / h acceleration, release 60% of the reserve power, quickly achieve high-speed overtaking.
Second, the new car is less than 200,000 yuan 100 kilometers accelerated by 7.9 seconds
Geely's research and development of hybrid technology has a long history, and after a long period of exploration and exploration, it finally locked in the existing planetary gear electromechanical coupling system. Currently, it is equipped with the Thor God Intelligence Engine Hi · System X's Gilli Star Yue L Thor Hi · X is on pre-sale and is priced at 173,000 yuan.
According to the information on the official website of Geely, Geely Star Yue L Thor Hi · X is free of charge, long endurance and extendable range as the selling point, in the acceleration performance of 80-120km/h, it exceeds the Japanese hybrid by 30%, the maximum torque performance of the system is 1.5 times that of the Japanese equivalent hybrid, and matches the 3-speed hybrid electric drive transmission (DHT Pro), which saves fuel and power. In a state of full oil, Gilly Star crossed the L Thor Hi · X's maximum cruising range can reach 1300km, which greatly reduces range anxiety, NEDC 100 km fuel consumption of 4.3L, in the oil price climbing today can also save money.
Previously, Geely Star Yue L Thor Hi · X once ran 1426.1km with a tank of fuel in the challenge, which was much higher than the 1300km marked, while the fuel consumption of 100 km was only 3.9L, which fully demonstrated that Hi · Low fuel consumption of the X-hybrid system.

Conclusion: Domestic hybrid vehicles are catching up
Geely said that in the next three years, it will also provide a variety of power combinations including strong mix, long-endurance plug-in hybrid and extended range hybrid, and install them on more than 20 models of Geely, Lynk & Co and other brands. After that, Geely will continue to follow the "new four modernizations of power" strategy of power efficiency, drive electrification, energy diversification and intelligent control, and build a full-dimensional diversified and cleaner travel ecology.
In the past, hybrid technology has been controlled by Nissan enterprises, like Geely willing to sink their hearts and seriously overcome the high-tech technology of local enterprises out of the reality is valuable, I believe Geely will soon catch up with the pace of competitors in terms of sales. In the future, there may be more domestic manufacturers in the hybrid market, and Geely will bring consumers more diverse choices and a better driving experience.
