There is no doubt that since the birth of internal combustion engine , the limit of automobile energy saving ability has been refreshed, but in terms of orders of magnitude, it still needs to be calculated from the support of electric drive in the past two years. For example, the current Xingyue L extended-range electric version has completed a further refresh of the battery life of the extended-range electric SUV. The comprehensive battery life of 1300km is really exaggerated. Of course, the fuel consumption of power loss per 100 kilometers has also dropped to 5.3L, which is quite eye-catching for a compact SUV. So how did the electric drive system enhance the Xingyue L extended-range electric version? How much technical value is there?
This "extended range" is more complicated than
Strictly speaking, the Xingyue L electric version's extended range system is not the "extended range" in the traditional sense, but the "extended range" that is more literally in line with the meaning. First of all, in the traditional sense of extended-range hybrid system, the engine function is only the power source that drives the generator to rotate, and it is completely decoupled from the vehicle driving mechanically. In more sense, the traditional extended-range electric motor is essentially closer to the electric vehicle , and is also the root of the word "tandem".
And the main difference between this hybrid system equipped on the Geely Xingyue L electric version is the three-speed DHT Pro dual-motor hybrid transmission it is equipped with. In addition to allowing the power system to work in pure electric drive, brake recovery, and extended-range power generation, this transmission can also directly drive the wheels through the gear change of the clutch. In order to further reduce fuel consumption, Geely further emphasizes its extended-range attributes. But in any case, Geely's solution not only ensures the experience of electric drive silky driving, but also expands the coverage of application scenarios as much as possible. In summary, the competitiveness is still relatively full.
Energy-saving technology, how much does it cost?
After reading the overall architecture of Xingyue L electric version, let us really take a closer look at the technical core of this set of power in detail, which is also the main bearing point of this car's super long range.
First of all, the Xingyue L electric version is equipped with a 41.2kWh flat battery with a CTP configuration to support a 205km WLTC pure electric battery life. This configuration ensures that the Xingyue L electric version can have the ability to travel in daily cities at low cost, and this large capacity can also minimize the fluctuations of the engine at the working conditions. In most cases, the 1.5T engine equipped with the Xingyue L electric version only needs to work at the highest energy efficiency point.
Xingyue L electric version In addition, we have to mention this hybrid special engine code-named DHE15. This not-so-conspicuous engine actually has a very radical technical support, such as the 13:1 ultra-high compression ratio, such as the Miller cycle, which allows this engine with a maximum power of 110kW, in addition to having a high thermal efficiency of 43.32%, it also has the ability to drive the smooth experience of the whole vehicle. The technical content is relatively high.
architecture foundation, and its ability to reflect
. Among the many characteristics of Thor L electric version, there is another basic point that needs to be emphasized, that is, e-CMA as the architecture foundation.
Overall, this seemingly quite "metaphysical" thing gives Xingyue L electric version powerful expansion performance, in which the built-in neural network system can gradually optimize many control parameters and indicators according to the user's driving habits. Of course, OTA can also provide more functional possibilities for the product in subsequent development. This is an indispensable contribution to the Xingyue L electric version.
In addition, in the high-voltage system architecture, in addition to 6.6kW home slow charging, Xingyue L electric version is also equipped with a DC fast charging capability that supports up to 85kW, shortening the charging time in individual scenarios. At the same time, Xingyue L electric version also has an external discharge capacity of 3.3kW and supports parking power generation, which should be a good advantage and highlight for camping enthusiasts.
Product car sensation:
Overall, the Xingyue L electric version, which is known as "extended range" but is actually not the traditional "extended range" in the sense of "extended range" is the best response to current user needs.On the one hand, the ultra-long battery life can erase the mileage anxiety of long-distance travel. In addition, the pure electric battery life of 200km+ allows daily travel to be extremely low-cost, giving travel freedom and rich experience. The performance of strength is considered clear and realistic.
