Geely Automobile is continuing to deepen its cultivation in the field of hybrid technology.
On December 24, after the thunder god He · At the X Hybrid Technology "Live Open Season" event, Hoshigoku L Thor Hi · The X model ran 1426 km with a fuel consumption of 3.9 L/100 km with a tank of fuel. In this way, it demonstrates the technical level of its 3-speed hybrid electric drive system, DHT Pro.
At the same time, Geely opened its Thor PowerED DHT smart micron factory to the outside world for the first time. In the company's view, the plant is an important part of the "strongest system force" for full electrification in the era of Technology Geely 4.0. According to reports, the factory has invested billions of yuan and plans to produce 300,000 transmissions per year in the first phase. The level of automation exceeds 70%.
"Micron-level" is the key word for the plant. According to Geely, the production accuracy of the DHT Pro electric drive system in the production process reaches the "micron level", which is "two levels of accuracy" compared with the traditional transmission manufacturing process. Based on this, the service life of the DHT Pro hybrid electric drive system is expected to reach 350,000 kilometers.
In addition to the production process, the plant also strives for lean management processes. The DHT Pro integrates a 60 bar high-pressure hydraulic system with the valve body assembled in a "separate chamber" in a micron plant.
This chamber can be cycled 25 times per hour for a dust-free assembly workshop that meets IC-class standards. It is worth mentioning that the DHT micron factory also adopts the "0 error" intelligent optional system to achieve micron-level control of the entire assembly process and ensure the quality of the whole life cycle.
According to reports, each DHT Pro offline must go through the "graduation examination" and establish a lifetime file. In this regard, Geely said that the two major test systems of EOL testing and valve body testing, which cost hundreds of millions of yuan to build, can check all functions and NVH performance, and strive to achieve 100% qualified offline.
In the fuel saving challenge, hoshikoshi L Thor Hi · X oil-electric hybrid version, the average fuel consumption of 100 kilometers is about 4.3L, which is lower than the CR-V hybrid, RAV4 hybrid and ideal ONE that travel at the same time.
As the intelligent energy control hub of the entire hybrid system, it can realize the functions of pure motor drive, oil-electric hybrid drive, intelligent power generation, intelligent energy distribution and 3-speed variable speed increase, and the electricity and fuel are "lossless" output, so that the Star-Over L Raytheon Hi · X oil-electric hybrid version becomes a hybrid model that can be paralleled in the full speed domain, with a combined power of 180 kW and a system integrated torque of 540 N·m.
In addition, the car's electric drive system has self-learning capabilities. The 3-speed hybrid electric drive transmission DHT Pro can be fully combined with the cross-domain fusion of intelligent electronic and electrical architecture GEEA 2.0 to achieve a hybrid system FOTA upgrade, which can identify the driver's driving habits, road congestion, and realize driving mode adaptation.
It is clear that Geely is trying to break the field of hybridism that has been dominated by Japanese brands for a long time through self-developed technology. In terms of the performance of this event, the results are indeed remarkable. However, as a new model equipped with new technologies, its durability and stability need to be tested for a longer time before conclusions can be concluded.
