Introduction | PHEV dispute
Last week, the car gathered an article about 100,000 yuan.
From the official introduction, this system compares the actual driving needs, which will have obvious competitiveness in the existing PHEV market, but still need to observe reliability. The article has been enthusiastic, and the extreme criticism of a large number of Di powder has been received, but also has received a lot of real users.
So the car gathers the iron, take the two sets of current autonomous hybrid systems, come with everyone to talk about the development of existing mixed technology.
At present, the domestic hybrid market is mainly divided into two major blocks, which is based on BYD, the public. The represented PHEV market and the HEV market dominated by Toyota, Honda.
The state’s attitude is also very clear. Although the two are not good to say from the perspective of technology, the Phev model is listed as a new energy model, you can enjoy the national subsidy, or you can go green. brand. The HEV model has been excluded from the subsidy list because most patents have been held by Japanese car companies.
From January to December 2020, only 5 PHEV models have more than 10,000 annual sales. Note that the annual sales volume, PHEV sales in the first ten models of 2020 accumulated sales is 125,398 units. As a comparison, Honda China’s sales of HEV models in 1999, and Toyota’s number should be more, because it is equally put on the A-class car in Corolla early, Lei Ling, is equipped with a mixing system.
Why do you have a green card, free purchase tax, but it’s nothing but the two-field mixed car sold by the fuel truck? There are two aspects of the answer, one is the price, and the other is the actual needs of the user.
First, the price of PHEV models is of course very simple, and the state regulations must reach a hard pure battery life mileage to subsidize, so they must be equipped with a large power battery.
Take the highest sales volume of the BMW 5 Series PHEV for example, its battery capacity is 17.7 kWh, this piece has spent nearly 20,000 costs, plus The two sets of systems are parallel, not only with motor, but also more complicated by the control system, so it is more expensive than ordinary fuel gifelings. 
So, although expensive, but true, and has the advantage of green cards and subsidies, the PHEV model should be very popular. However, the actual results are large, mainly because of the second point, that is, it is contrary to the actual needs of users.
For ordinary users, if I have charging conditions, then I prefer pure tram type. Although long-distance continuity is not, in the main situation of urban area, the pure tram type is obvious: Direct, accelerate linear, NVH excellent, lower use, and lower maintenance, after all, three items Two big things.
This is the embarrassment of the PHEV 1.0 era.
Do you say that car companies don’t work? It is not. After all, BYD did the Tang DM to get from 0-100km / h to speed 4.3 seconds.. But it is indeed limited, and the market of PHEV has not been warm. In 2020, the new energy sales broke out, which has greatly increased the pure electric car, and the PHEV relationship is not large.
Second, PHEV 2.0, add yourself “hematopoietic” army
Although it can eat subsidies, the sales volume of models that spend greatly developed is limited, for car companies The resulting profit is also limited. Therefore, major cars also seek changes, the core ideas are better, but they also meet the needs of users.
That is that the PHEV model has to learn from “hematopoietic” in addition to “power consumption”. Let the user can not charge, and enjoy the fun of the oil and electricity. This idea and Toyota, Honda are like, but the way to achieve is different, the first thing that is first in Toyota and Honda is not the same.
Toyota’s thinking is still based on engine, and dynamic coupling of a set of planetary gear systems it is designed, allowing the motor to intervene, “Help” Take a high fuel consumption.
Honda’s ideas is the main motor, through a set of power shunt systems, in most cases motor driver, the engine is specially powered, only high-speed flow, and When the acceleration and ultra-high speed are combined with the motor.
Toyota’s design is more complex, but from the results, the fuel consumption of the two is similar, Honda has realized oil through multi-purpose electricity and multi-power generation, and the power performance is more excellent.
I saw someone saying that Honda’s I-MMD system is “plagiarism” BYD’s F3DM in 2008, and the car gathered to take the information of this car.
The overall completion degree of F3DM is relatively low, and the core components are not associated with DM-I. The part of the engine and the motor cooperates more confusing, so this car is rooted. Didn’t sell, even the technology route is also interrupted, saying that it is still because it is not easy. It is said that there is not much basis for it.
Of course,It is said that the DM-I and the Great Wall DHT of BYD are not. As if the double clutch speed box, the public is just to avoid Toyota’s patents adopted a new idea, and the configuration of them is not the same. So the public can build, the Great Wall, BYD, Geely can also create, no one click who said.
The mixed system of BYD and the Great Wall is also the same, but they only increase the “hematopoietic” capability for the mixing system, thus getting rid of the restrictions of the charging pile, itself is implemented and the Toyota, Honda is also different, not talking Plagiarize.
Third, the Great Wall DHT, the oil and electricity is more heavy
In the interpretation of the BYD DM-I system, the DM-I system has been mentioned, Honda i-mmd is similar, that is, the electric drive is mainly driven, but further increases the proportion of the electric drive, and is equipped with a larger motor.
What is the Great Wall DHT do? Its practice is just a way to be in Toyota and Honda, ie the use of oil and electricity. 
According to the DHT of the Great Wall, it is still relatively close to I-MMD and DM-I, engine and generators, and drive motor coupling, There is a pure electric drive, a series engine power generation drive, and the parallel drive (at this point can also be automatically driven separately) three drive mode, and energy recovery.
This shows that regardless of the Great Wall or BYD, the relatively simple driver is consistently selected.
A gameplay that cuts into a dozen working conditions like Toyota, really don’t love to play. Therefore, Toyota’s proud is can’t, and it is also an open patent, and it is planning to transfer THS to Guangzhou Automobile, Geely, which is this reason. Everyone doesn’t want to leave this road, I destined that your skill is high and widowed, it is more and more.
The working model of DHT is actually similar, that is, start or low speed creep adopts pure electric drive; medium speed is engine power generation, drive motor drive; high-speed cruise, engine direct drive, urgent acceleration or super High-speed use engine direct drive and motor drive simultaneously.
However, it is also slightly different from Honda, which has been exposed to Haval H6 lemon DHT versions, equipped with 100KW and 130KW two motors, matching 1.5L and 1.5T, two dedicated engines. BYD Song Plus DM-i’s two motors are 132KW and 145KW, respectively, indicating that the dependence of the DHT system should be smaller than DM-I.
Since the motor is smaller, how does DHT make up this? The answer is
It is a set of two gear gear than Honda and BYD
, which is specifically for engine services. We can understand the economic gear and sports. 
That is, its engine can be switched to an economic gear, focusing on power generation, when charging treasure. You can also switch to the motion gear when you need a full engine force, and have a stronger performance. There is also a saying that when it is transformed in the middle, it can also use the engine direct drive, which is more powerful than driving the generator, saving two energy transmission, efficiency can increase 3% -5 percentage.
But the information we can get is limited, and it can only be said that the key point of this system is on its fixed-axis gearbox, which makes this system to achieve the effect of the oil and electricity.
Four BYD uses a larger motor to maximize the proportion of the electric drive, which is probably that its accumulation in the three-electric field is deeper.
The Great Wall DHT uses an oil and electricity to increase, and the mechanical transmission is also increased, mainly because it is more experience in the field of traditional power assembly. 
However, from the results, it seems to be the same.
Great Wall official data, DHT power system comprehensive efficiency is 43-50%, Haval H6 lemon mixing HEV version of the comprehensive fuel consumption of 4.6L / 100km, HEV version fuel consumption is basically equivalent to BYD promotion ” “Fuel consumption, Song PLUS DM-I low-power version promotion has a comprehensive fuel consumption of 4.4L / 100km. Both of them are basically flat, and BYD can be considered a little bit a little bit. According to the Great Wall Official Promotion, Haval H6 Lemon Mixing HEV version of the system power can reach 180kW, 0-100km / h accelerate as long as 7.5 seconds, the official acceleration time of the Song Plus DM-I high-time version is 7.9 seconds. The two are basically flat, or the Great Wall is slightly won.
BYD achieves a lower fuel consumption by employing extreme thermal efficiency engine, as well as more electric drives. The Great Wall has achieved stronger performance by increasing the “role specific gravity” of the engine, including a special transmission. The advantages of both parties were played out, but the gap between the two was basically between Jiefone.
At present, the two systems are still in the “cloud evaluation” stage, and the best is not good, and the car is more willing to believe in their assessment and user real voice. Therefore, it is no longer to conn then.
The doubt of the car is still in that the newly developed super efficient, ultra-high compression ratio engine, how is the carrying performance? And what level can you reach? Before the word of mouth without the real owner, it is a good or singing, and the meaning is not big.
No matter what to say, at least from the perspective of design compared to the PHEV model of 1.0 era, the newly published architecture of BYD and Great Wall is indeed more It meets the actual needs of most users. One power feeling is good, but also the ultimate oil model, no matter how you can go green, it is certainly more powerful than the existing PHEV.
For our users, no matter the black cat white cat, it is a good cat. Don’t bring rhythms by the outside comment, everything is based on actual. Is it a mixed mix or a mixed mix, or a strong mix, it is a good, easy to use, and worry is the king.
