Introduction: Starting from the second half of 2021, the hybrid technology of the domestic automobile market is slowly blossoming, no longer a monopoly or that each technology is similar, and the unique technology with brand characteristics has gradually emerged, such as Nissan's e-POWER, the GREAT Wall system's DHT, Geely Raytheon Power, BYD DMi, etc., all of which make people shine, so what are the different shining points of these new technologies?
Many friends may have a question, why in the past year or so, major independent brands have mushroomed and listed their own new "super hybrid system", what is the reason for the promotion? After all, in the first two years, because of the traditional plug-in mix, the problem of high fuel consumption and expensive price made it more and more "unpopular", and the market performance continued to decline, why did it suddenly break out?
National policy becomes the strongest "catalyst"
Some people will think that because of the DM-i hybrid system launched by BYD, the market response is too good, so major brands have also followed the trend, thinking that the process of turning fuel into pure electricity cannot be omitted. But we should also take into account that the hybrid systems released by major brands are all "black technology", and it is obviously unrealistic to launch them in such a short period of time. Therefore, it has little to do with the popularity of BYD DM-i, but the new policy of the state.
In October 2020, the state officially released the "Energy-saving and New Energy Vehicle Technology Roadmap 2.0", which put forward the development plan for the development of the mainland automobile industry in 2035, and the carbon emissions of the mainland automobile industry will reach a peak in advance of the national carbon reduction commitment around 2028, and by 2035, the total carbon emissions will drop by more than 20% compared with the peak.
Seeing this, you may still have doubts, don't the major manufacturers we are familiar with "plug-in hybrid" claim that the fuel consumption of 100 kilometers is as low as 1L or 2L? Such performance seems to be fully able to meet the policy needs of the country. It is true, but as mentioned earlier, it is still very harsh to achieve such a low fuel consumption condition, first of all, to be fully charged, the test standard is not uniform, and most of the friends who want to choose these plug-in models are not often charged this condition, which also leads to the fact that in the state of power loss, its fuel consumption will even be higher than that of pure fuel. Therefore, after everyone understands its "habits", the plug-and-mix market is becoming more and more "unpopular".
Everyone does not want to charge, is not there still 48V light mix this option, which is also a direction that many brands are vigorously developing. But we also know that the 48V light mix system on the improvement of fuel consumption is not obvious, through the BSG or ISG motor, more is to make the start smoother, the driving texture has improved, the theoretical fuel saving rate of this technology is only 14-17%, so it can not meet the requirements of the "Energy Saving and New Energy Vehicle Technology Roadmap 2.0".
Therefore, for brands, in order to meet the national policies and launch a hybrid system that allows users to accept their favorite, it is necessary to come up with some real skills, and the "Energy-saving and New Energy Vehicle Technology Roadmap 2.0" has become a "catalyst" for the mushrooming of major brands of hybrid systems.
What "super hybrid systems" should we pay attention to?
Although in 2021, major brands have launched their own "super mixing system", they have their own very distinctive names, and the technical highlights are different, but the effect they achieve is indeed surprisingly consistent, that is, the ultra-long endurance, the feed state is still low fuel consumption, pure electric endurance characteristics.
At present, we are most familiar with BYD's DM hybrid technology, also known as DM-i super hybrid system. Indeed, BYD in the domestic whether it is hybrid or pure electric market are in an absolute leading position, its DM insertion and mixing system although in the first two years of the market decline is more obvious, but more importantly, the popularity has increased a lot, this time can more quickly launch the DM-i hybrid system, and a large number of promotions, are related to their own strong technical strength.
This hybrid system is mainly composed of a hybrid special engine + a two-speed reducer + two motors + a clutch + a motor controller + a power battery. The Great Wall has also planned three sets of powertrains for this set of powertrains, namely 140 ~170kW, 180~240kW, and 320kW, which are suitable for models of different levels of size.
Chery Group also recently officially listed its first model equipped with star core power ET-i full engine supermix - Star Trail Wind Chase ET-i, star core power ET-i full engine super hybrid is composed of fuel engine + full-featured DHT gearbox, according to the official said that it has the technical advantages of 3 engine 3 gear 9 mode 11 speed, transmission efficiency can reach 97.6%, the comprehensive fuel consumption under full power condition can be as low as 1L/100km, even in the feed condition fuel consumption is only 4.8L/100km, The overall performance is also very good.
After that, the Geely brand's Thor Power is also a high-profile debut, and in comparison, it brings us much more things, because it has to take into account a variety of hybrid forms, so Geely also adopts modular output, including efficient engine, efficient transmission, Thor Intelligence Engine Hi · X and E drives. Recently, the more popular Star Yue L has become the first one equipped with Thor's Intelligence Engine Hi · Models of the X system.
summary
Therefore, the factors that can make the domestic hybrid system mushroom like mushrooms are two factors, one of which is the national policy, and the other is the user's usage habits. And with the advancement of time, I believe that other domestic brands will also launch a hybrid system that meets the national policy, let us wait and see. Regarding the hybrid systems that have been announced, in the next period of time, the author and my colleagues will also introduce them in detail for you, their technical highlights and market advantages, please continue to pay attention to them.
