The "four consecutive increases" in oil prices and the cruel reality of No. 92 gasoline breaking through 8 yuan have made many people begin to re-examine their car purchase needs. Of course, under the bug that the charging inconvenience and mileage anxiety of pure electric vehicles can still not be effectively solved in the short term, hybrid vehicles seem to have become "fragrant" overnight.
With the hot sales of plug-in hybrid models, in the past Two months, BYD has become the top brand sales champion in China with more than 90,000 units – of which the DM-i model (plug-in hybrid model) sold 44,000 units, compared with 2288 units last year.
Dm-i model sales soaring behind two reasons, one is that DM-i models enjoy purchase tax reduction and green card, plug-in hybrid models of green cards in some areas are unlimited, the degree of freedom of use has been greatly improved; second, DM-i models fuel consumption is basically about 5L, and the price is extremely close to the same level of traditional fuel models, even if users in unlimited areas face continuous increases in oil prices, they will involuntarily have a "just need" idea for fuel-efficient DM-i.
Since last year, Great Wall Motors has also begun to develop hybrid models, and unlike BYD, Great Wall Motors is a parallel route of DHT-PHEV plug-in hybrid in hybrid technology.
BYD DM-i starts with a pure electric endurance of 51 kilometers, and DHT-PHEV starts from a pure electric endurance of 110 kilometers, attracting high-end users in first- and second-tier cities with the difference point of long endurance. The DHT gasoline-electric hybrid model uses cost-effectiveness to achieve "suppression" of traditional fuel vehicles.
GAC did not "idle", directly through the "take-ism" way, from Toyota to get the THS hybrid system, and directly loaded into the second generation of GS8.
On March 1, Weipai once again launched the MOCHA DHT-PHEV with a pure electric range of more than 204 kilometers. At this point, Weipai's models have achieved full hybridization. On the second day of the launch of the Mocha DHT-PHEV, Chery's plug-in hybrid Xingtu Wind Chasing ET-i was also listed in Hangzhou, with a pure electric endurance of 105 kilometers. Coupled with the pure electric 100 km Tiggo 8 Kunpeng e+ listed in January this year, Chery Automobile has also made a certain breakthrough in the field of plug-in hybrids.
In addition to BYD, the Great Wall and Chery, the Hoshikoshi L, which has released a pre-price at the end of last year, equipped with the Thor hybrid, seems to have encountered some kind of situation and has not yet been officially listed. Interestingly, in the case of the hybrid Star Yue L "thunder and heavy rain point small", the plug-in hybrid Changan UNI-K will be officially listed on the evening of March 10.
The essence of competition in the automotive industry is technological competition, and it is cost competition on the basis of technological competition. There are indications that under the wave of electrification and rising oil prices, hybrid vehicles will most likely become an alternative to "pure fuel vehicles", especially plug-in hybrids.
To put it bluntly, without plug-in hybrid technology, it will soon be "mixed" in the automotive market.
For example, in terms of February data, in terms of passenger car sales, BYD even surpassed the "SAIC Volkswagen" that had always been high - which was unexpected by many people. But this is the huge effect of technology, market trends, and the "superposition" of consumer demand.
Technology is only the "ticket" to participate in the competition, and the quality of technology is the key factor in whether it can win. So, in addition to the mature Toyota THS brought by GAC, who is better than BYD DM-i, Great Wall DHT, Chery Kunpeng DHT, Geely Zhiqing Thor Hi-X and Changan iDD?
Realistically speaking, the hybrid power that Chinese brands concentrate on is the result of "borrowing" the logic of Japanese hybrid power.
The biggest difference from parallel hybrid is that the hybrid technology route realized by Chinese brands now has an exclusive hybrid transmission. Although this hybrid gearbox has the title of a gearbox, it is more of a differential, without traditional gearing, but through the differential principle, the two sets of power output of the engine and the motor are coupled into a power output like "kneading dough", corresponding to a separate drive shaft, and then form a hybrid architecture of the hybrid.
Of course, not all of China's brand hybrid technology is a relatively advanced "hybrid architecture", and Changan iDD is the P2 parallel architecture of "single motor". The biggest drawback of the P2 parallel architecture is that it is impossible to achieve the maximum efficiency of the engine and electric motor.
Unfortunately, the P2 architecture performs well at full power, but in the feeder state, the engine condition deteriorates extremely, and fuel consumption soars. Some insiders have calculated the data of plug-in hybrid UNI-K currently released, and its feed is really fuel consumption of more than 8 liters per 100 kilometers. The feeder of the product under the mixed structure is basically about 5-6 liters per 100 kilometers.
In the Chinese market, European brands have long launched a number of plug-in hybrid models, basically P2 single motor architecture, product reputation is very bad, so it also leaves a "power is a dragon is a worm" in the market.
The comparison in this article is the mixed architecture, so the Changan P2 single motor architecture is naturally not within the scope of our discussion - the P2 single motor architecture and the dual motor hybrid architecture are completely not on a horizontal line.
After talking about Changan iDD, then we will talk about the mixed architecture of several other brands. In fact, there are many influencing factors that affect the indicators of the hybrid system, such as power management system, hybrid logic and so on.
One of the simplest examples, Toyota's THS hybrid system has used nickel-metal hydride batteries for so many years, and it has not seen the same as Tesla's lithium-ion batteries now, which can decay at every turn - it is reasonable to say that nickel-metal hydride batteries with memories should be the existence of "the most crotch"--but this is not the case.
However, all hybrid hybrids have to solve a core problem, that is, the power coupling of the engine and the electric motor. From a common point of view, the coupling logic of BYD DM-i, Great Wall DHT, Chery's Kunpeng DHT and Geely Lei's Intelligent Engine Hi.X are similar to the Honda i-MMD hybrid system.
At the heart of their power coupling is a multi-chip clutch-type mechanism. This principle is somewhat similar to the sliding clutch of the motorcycle, through which the output of the engine and the electric motor is coupled through the sliding membrane of the clutch. In this process, the electric motor plays the role of a comprehensive auxiliary engine.
The difference is that these sets of hybrid systems are slightly different in the corresponding deceleration mechanism, and the BYD DM-i super hybrid system only has one level of deceleration, so in this process, the speed regulation dimension of the motor will be much larger. The Great Wall DHT uses a two-speed reducer, that is, a two-speed gearbox, so that the power after the coupling of the engine and the motor will also change the speed ratio of the first-stage transmission, and the speed regulation pressure of the motor is smaller, and the power performance of the vehicle can also be better under the premise of consistent engine output.
The Geely Ray Divine Intelligence Engine Hi.X distinguishes between the configuration of the 1st gear DHT and the 3rd gear DHT Pro, corresponding to the normal and more powerful power output versions. Chery Kunpeng DHT is also in the third gear. So talking about this will find that the hybrid system of the Chinese brand has used the gearbox to stir up and go out of the circle - too internally coiled - has risen from low fuel consumption to the height of both energy saving and performance.
Of course, under the premise of technology, the next step of competition will involve "cost control", that is, the same technology and products, whose price will be lower, who can occupy an absolutely dominant position in market competition. Technology and cost, one can not be less.
Written in the back: In hybrid technology, the rapid development of Chinese brands has left European brands far behind, and has the stage of grabbing the market with traditional fuel vehicles at lower prices.
For consumers, buying a fuel-efficient, good-performing Chinese brand hybrid model or buying a joint venture brand traditional fuel vehicle is no longer a choice.
Brands that do not have "good hybrid technology" are becoming more and more "mixed".
