Since entering 2021, the development of domestic hybrid technology has entered an explosive period. Great Wall released lemon hybrid DHT technology, and Geely launched Thor Hi · X hybrid technology, Chery and Changan also launched Kunpeng DHT hybrid and blue whale iDD hybrid respectively.
Why do so many domestic head car companies want to "get together" to push hybrid technology? In fact, if you look at the insurance data of the PHEV model in November, you can know that BYD has already gained fame and fortune one step earlier.
In November's PHEV model top 5, BYD occupied four seats, three of which were DM-i models, which completed the "three arrows" in March this year, and in the top ten models in the upper insurance volume, BYD also occupied five seats. However, there are also "fish that slipped through the net", that is, the ideal ONE and Cyrus SF5 as new forces, but also successfully broke into the top ten.
What are the characteristics of these hybrid models? Let the kung fu car take everyone to see it together.
(1) BYD DM-i, fast, provincial, quiet, smooth, green
There is no doubt that BYD's DM-i super hybrid system is the biggest winner in the hybrid market this year. Song PLUS DM-i and Qin PLUS DM-i have become well-deserved blockbusters, and their sales in November have exceeded 10,0002, and they are still in the production capacity climbing period.
In contrast, the total number of PHEV passenger cars in 2020 is about 208,000 units, which means that normally, the annual sales of these two cars have exceeded the sales of all previous PHEV models combined. This is no longer the concept of a winner in the market competition, which is to create a new market.
The reason for the success of DM-i hybrid is not complicated, in fact, it is the five characteristics of official publicity, fast, provincial, quiet, smooth and green. Needless to say, take Qin PLUS DM-i as an example, it is equipped with a 145kW permanent magnet synchronous motor, the maximum torque of the optical motor reaches 325Nm, not to mention that the dm-i architecture can also synchronize with the motor, the new car completes 0-100km/h acceleration time of 7.3 seconds, absolute steel gun level. And because 99% of the urban area is pure electric drive, it is naturally smooth enough and strong enough.
Its province and green are actually complementary, because Qin PLUS DM-i is equipped with a high-performance blade battery, which can achieve a pure electric endurance of 110km, which can not only be on the green card, but also ensure that the new car is "oilable and electric", and the cost of the car is naturally greatly reduced. At the same time, even in the "feed-in" state, the power generation is generated by the Xiaoyun-plug-mixed special 1.5L high-efficiency engine with a thermal efficiency of more than 43%, and the electric drive is still used, which can achieve a "feed- " fuel consumption of 3.8L/100km, which is also saved to the extreme.
And the price of BYD DM-i models is not expensive, like the price of Qin PLUS DM-i is 10.58-14.58 million, and it can be exempted from purchase tax, which is still cheaper than Japanese hybrids.
The key bydir is that BYD's hybrid system has basically achieved the ultimate in traditional oil-electric hybridization. The engine efficiency is extremely high, the motor drive efficiency is extremely high and the performance is powerful, the battery technology is mature, and there is no gearbox, whether it is cost control, or technical architecture, whether it is fuel saving or performance play, it is currently very advanced.
With the launch of the destroyer 05 and subsequent Models such as the Han DM-i, IT is foreseeable that BYD's advantages will be further expanded.
(2) BYD DM, which is about to upgrade DM-p
BYD has two DM models that have reached the top ten in sales, namely Han DM and Tang DM. This shows that although the market performance of DM technology is not as good as DM-i, the influence is still good.
The biggest feature of dm system is that the performance is stronger than DM-i. Taking the Han DM as an example, it is equipped with a 2.0T engine, and the Song PLUS DM-i, which is equivalent in weight year-on-year, is equipped with a 1.5L or 1.5T engine. In the actual driving process, the DM system will implement the strategy of "electricity first and then oil", that is, the starting and low speed stages are driven by the motor to ensure that the acceleration is smooth and quiet, once the power demand is larger, such as the need for floor oil to start or accelerate overtaking, the engine will intervene and the motor synchronous drive to obtain a stronger power output. The system also retains the gearbox, which is used to complete the coupling of the two powertrains.
Taking Han DM as an example, its time to complete 0-100km/h acceleration is 4.7 seconds, which is definitely a supercar level, and this data is still underestimated, and the previous media measurements have easily run to 4.38 seconds. Therefore, the biggest feature of the DM system is actually that it is powerful, so it sells better on high-end models such as Han and Tang, because the performance needs of users at this level are stronger.
Of course, this system also has disadvantages. That is, although it also has a HEV model, it does not perform as well as the DM-i model in the "feeder" state, after all, the latter is designed for "feeder" to some extent.
Before the Guangzhou Auto Show, bydir Tang DM-p spy photos have been exposed, but unfortunately it did not appear at the Guangzhou Auto Show. This is a new set of technologies developed by BYD on the basis of the current DM technology, and its biggest feature is the performance of the existing DM technology, while also greatly improving the performance of "feed". There is a powerful performance output, but also no longer worry about performance when there is no power.
According to the previous information, the 0-100km/h acceleration of Tang DM-p can be achieved in 4.1 seconds, and the "feed-in" fuel consumption is as low as 6.5L/100km, although it is a little more than the fuel consumption of Tang DM-i, but the speed is nearly half faster, and it is still a very fuel-efficient type in the same level.
It is conceivable that when the DM-p technology is covered, BYD's super hybrid performance car will shine again.
(3) The extender hybrid shines brightly, is it really on the road to Jane?
In addition to BYD's continued popularity, there are two new forced range extender hybrid models, the Ideal ONE and the Cyris SF5, which also entered the top ten. In the past, everyone's concept, range extender hybrid is actually an old technology, why has it risen in recent years? In fact, it still has to start from how it works.
The extender hybrid architecture should be the simplest of all hybrid architectures, in short, the engine is only responsible for generating electricity, and the electric motor is only responsible for driving. The engine generates electricity to the battery, and then drives the motor through the battery, which is equivalent to making the battery small, but attaching an engine to supply it with backup energy.
There are actually many advantages in this way, first of all, it must solve the mileage anxiety, and the power is not enough to the top of the engine. The second is 100% motor drive, the driving experience is also absolutely smooth, fast acceleration, the engine is only responsible for generating electricity, can always run in an efficient range. Of course, the disadvantages are also obvious, that is, from the direct drive of the engine to such a complete set of energy transmission, there is inevitably energy loss in the middle.
Judging from the technological development in recent years, manufacturers have put new ideas into practice. The engine can directly drive the motor, turning the battery into an energy pool, which is only used to take over the excess electricity when driving, and then help drive when necessary. In this way, the load on the battery becomes smaller and the energy transfer is simpler.
The most typical is the ideal ONE, although it is an electric vehicle produced by the new forces, it is reasonable to have little engine technology accumulation. But it purchased a Mitsubishi 1.2T engine, and through the relatively simple architectural coupling of the range extender, it is even more fuel-efficient than the same level of fuel vehicles. Moreover, it makes the battery bigger and becomes oilable and electric, which basically solves the user's commuting car needs.
Judging from the hot sales of the ideal ONE and the Xilix SF5, it is of course better to be able to support the direct drive of the engine like BYD, at least at high speed. But taking the extender hybrid route, the architecture is simpler, the control is simpler, and the urban area is enough, which is actually quite good.
Perhaps, range extender hybridization will usher in a new wave of development in the future.
(4) Kung Fu shooting
In fact, there is no backward technology, only suitable technology. BYD's DM-i, the upcoming DM-p, the biggest advantage is actually the demand for cars for the target group, the key price is still appropriate, and naturally it stands out. The relatively simple range extender hybrid is enough for many people, and the Ideal ONE sells well as the Cyris SF5.
