On December 24, Geely held the Thor God Spirit Hi · X Hybrid Technology "Live Open Season" activity, and synchronously opened the new Raytheon Power DHT Smart Micron Factory, through the form of cloud release to unveil the 3-speed hybrid electric drive DHT Pro quenching road.
In the past, Japanese brands or domestic brands often kept a secret about their hybrid technology. It has been many years since the hybrids of the two fields have entered the country, and most people still do not understand how they work. Remember that there was a debate in the car circle before, and it was difficult for even front-line engineers to say clearly in which state of operation the maximum power of the Honda i-MMD appeared.
But Geely is good, not only all the technical details are revealed, the whole long endurance Open is broadcast live, and even the factory details are released, which is still the first time in the car circle.
Why does Geely choose to play the technical bottom card as a "clear card"? Where does its confidence come from? Let the kung fu car take everyone to see it together.
With the advantages of both fields, Thor Hi · X-hybrid rolls out to new heights
Speaking of oil-electric hybrid, many people will think of Toyota and Honda for the first time, one is the pioneer and promoter, and the other is to break the technical blockade, which can be described as a momentary Yuliang.
Toyota Hybrid pays attention to "peak shaving and valley filling", that is, the motor as a supplement to solve the inefficient part of the engine; Honda Hybrid pays attention to the electric drive, the motor uses more electricity, the engine generates more power, and realizes fuel saving through more electricity.
Both have advantages, but they also have drawbacks. Take the Accord hybrid and Camry hybrid as an example, the Honda i-MMD's low-speed performance is stronger, after all, it is equipped with a larger drive motor, which can maintain the performance output of low and medium speeds, but the high speed is a bit "dew filling", the engine power is small, the speed is not high enough; Toyota THS high speed is stronger, after all, its engine displacement is larger, the advantage of high-speed direct drive is greater, but the motor power is lower, and the acceleration ability of medium and low speed is not as good as Honda.
And Thor Hi · X hybrid, equivalent to taking the advantages of both. It is a system that can achieve full-speed parallel connection, and the engine can intervene at a speed of more than 20km per hour, which makes its medium and low speed acceleration capabilities far exceed that of the Toyota THS, and it is also equipped with the first 3-speed hybrid electric drive transmission, which can play a stronger performance than the i-MMD at high speed.
According to Geely's release of Hi · X hybrid working principle diagram, when the vehicle is driving at a speed of less than 20km/h, or frequent stop-and-go, the vehicle will be completely pure electric driving, and the engine will generate power in the efficient range. When the vehicle speed is mentioned above 20km/h, the 3-speed hybrid electric drive transmission DHT Pro will distribute the power according to the actual working conditions, such as the need for strong performance to match the 1st gear large-speed than the ejection acceleration, and the need for economy to match the 3-speed ratio fuel saving.
At a high speed of more than 80km/h per hour, DHT Pro also has a unique 3-speed variable speed increase torque, which can burst out up to 4920Nm output torque, and the comprehensive performance is 1.5 times that of the Japanese hybrid model of the same class, with super acceleration performance.
Can't say Thor Hi · X Hybrid does not borrow from the Japanese hybrid at all, but from the results, it is indeed better than the Japanese hybrid performance, but also more fuel-saving, after all, it also has 43.32% of the highest thermal efficiency record of the efficient engine support.
But the disadvantages are also obvious, just as everyone knows that 8AT must be more fuel-efficient than 4AT, its structure, control logic is more complex, and the volume is also larger. Geely, however, accomplished this amazing feat by integrating the power generation motor, the drive motor, 2 motor controllers and the 3-speed ratio variable speed increasing mechanism in an axial size of 354mm.
DHT smart micron factory, the bottom line of "Mingpai"
Gillican cut open his system structure and principle for everyone to see, largely because the opponent could not imitate. And it has such a "clear brand" of confidence, largely because of the DHT smart micron factory that has just opened.
The new factory contains two core architectures of micron-level engraving precision manufacturing technology and micron-level management system, which can comprehensively benchmark the manufacturing standards of Europe's top luxury brands. Its "micron-class" pursuit is two levels higher than the accuracy of traditional AT transmissions, giving the DHT Pro hybrid electric drive system a durable quality of 350,000 kilometers and excellent NVH performance.
Taking its vacuum quenching process as an example, it can control the depth fluctuation of the hardening layer in the range of ±0.1mm, and the deformation of the gear shape is less than 8 microns, the real internal toughness and external rigidity, which is twice as high as the industry standard; the EMA automatic water-cooled quenching machine is called "the wall breaker to prevent deformation", which can control the deformation of the planetary ring gear shape after heat treatment within the range of ±8 microns, and also allows the small amount of honing processing process after heating to be applied, which also breaks the status quo of the industry's internal ring gear heating.
The DHT micron factory also uses the "0 error" intelligent selection system, which can achieve fine grouping without difference, control the entire assembly process to the micron level, and ensure excellent quality throughout the life cycle.
The micro factory also prepared the most stringent "graduation examination" for the DHT Pro hybrid electric drive system, spending hundreds of millions of yuan to build a valve body test and EOL test two major test systems, all testing links more than 100 steps, and is 100% automatic detection, must achieve 100% qualified of the line. And like the college entrance examination, the DHT Pro hybrid electric drive system test will also establish a lifetime file.
Of course, there is also the first world-class virtual simulation AI laboratory with full simulation, full coverage and full development, such as the NVH laboratory with noise control at 8 decibels, the top climatic environment simulation chamber that can simulate the range of 5 meters to 5000 meters, the temperature range of -40 °C to 60 °C, and the high-performance laboratory that can clone the North Circuit of New York.
They are the biggest secret of Geely, not afraid of imitation, not afraid of stealing, because this powerful manufacturing ability is impossible to copy directly.
Facing the challenge head-on, Hoshikoshi L Thor Hi · X oil-electric hybrid version to be a subversive again?
When Hoshikoshi L debuted, the slogan was SUV subversive, and the reality is true, its emergence broke the barrier between the joint venture SUV and the domestic SUV.
And Hoshikoshi L Thor Hi · The X-Oil-Electric Hybrid Edition is clearly ready to be a hybrid SUV disruptor.
Geely's approach is simple and rude, directly allowing Hoshikoshi L Thor Hi · X oil-electric hybrid version to participate in the "extreme challenge", the debut of the challenge of 1300km ultra-long endurance, this mileage is considered to be the previous oil-electric hybrid car endurance ceiling.
What's more, Geely's challenge activity was broadcast live throughout the whole process, and invited authoritative media and users to participate together, and like the previous technical "bottom", it once again offered the "ming card" playing style. After completing the 22-hour trek in the convoy, Hoshigoku L Thor Hi The X hybrid version successfully completed the challenge and refreshed this record to 1426.1km, which is also the new limit of the hybrid.
The most crucial thing is the Star-Over L Thor Hi · The X fuel-electric hybrid version has a fuel consumption of only 4.3L/100km and a minimum fuel consumption of 3.9L/100km, which also refreshes the minimum fuel consumption record of the current large five-seat hybrid SUV, and also makes the new car the lowest fuel consumption HEV model in the same class.
In addition to hoshikoshi L Thor Hi · In addition to the X-electric hybrid version, the CR-V hybrid, RAV4 hybrid and the ideal ONE also participated in the challenge, and their fuel consumption was generally higher.
This shows that the strength of the world's first mass-produced 3-speed hybrid electric drive transmission DHT Pro is indeed quite strong, although the structure is complex, but it is too large for fuel consumption control. Moreover, the new car's 180kW system power and 540Nm system torque are also the strongest in the same class. It is foreseeable that the hybrid market is really going to change.
Summary of the President
On December 25, Hoshikoshi L Thor Hi · The X oil-electric hybrid version officially opened pre-sale, and its addition has caused a huge impact on the current HEV market. From the performance and fuel consumption performance, it has shown the strength to surpass the two fields, as a "long-range extendable range hybrid model without charging", it can be more tempting than the ideal ONE. And its DHT smart micron factory gives it the confidence of "ming brand".
How will the Star Elyse L Hybrid Edition disrupt the market?
