As the new energy market enters a new era of fierce competition among the whole people, the demanding degree of consumer demand for cars has also reached a new high.
Everyone is eager for a new car like “Polygon Warrior” on the market, which can bring a car experience suitable for the whole scene.
Of course, looking at the whole market, we have to ask, is there really such a model? It’s not true that there isn’t any.
Especially in the most mainstream car market, many products launched by Chinese car companies led by BYD in recent years actually have such potential.
Previously, various glorious models featuring cost-effective models were able to detonate the market, and many people said that it was because the price was low enough to achieve unprecedented market performance.
But at present, seeing that BYD’s newly launched Qin L DM-i and Seal 06 DM-i have once again aroused a strong response in the market, I think what we still rely on this time is still inseparable from BYD’s support for these two cars in core technology.
On a closer look, I believe that the role played by BYD’s fifth-generation DM technology is unparalleled.
As we all know, with the popularity of new energy vehicles today, most Chinese consumers who take “household” as the main demand for cars, the focus is nothing more than the spatial performance, ride comfort and economy of a car.
In fact, there is no need to say much about some platitudes of projects.
now Chinese car companies are still very good at it.
In contrast, the biggest difference in the product advantages of the major car companies is focused on the economy, that is, the cost of using cars.
Since its release in May, BYD’s fifth-generation DM technology, carried on Qin L DM-i Seal 06 DM-i, has become the key to consumers’ decision to pay for it, which must be strongly related to the momentum of the technology in systematically solving consumer pain points.
To a large extent, this year’s market trend is driven by new energy technologies such as plug-in and extended range.
Not only BYD, but almost all Chinese car companies are using it to build a product moat for themselves.
But on the whole, based on the existing consumer demand, the fifth generation DM technology, which is upgraded from the existing technology, is still more universal.
In fact, in the context of BYD, the original intention of the fifth generation DM technology is to redefine the new height of the plug-in technology with the technological highlights of speed, economy, serenity, smoothness and green.
That falls back to the technology itself, what BYD does is to optimize all aspects of this hybrid technology with its own experience, and finally achieve the goal of making users feel worry-free.
In other words, targeted technological optimization is still different from the uncontrollability brought about by complete technological innovation.
In the face of the largest number of users, this kind of unmistakable evolutionary logic will naturally have the attribute of being close to the people.
After all, at the price range of 10 to 150000, what consumers need is technological progress that can be seen, touched and reflected in the actual car experience.
During the measurement of new cars in Shanghai Railway Station, under the condition of keeping the same driving as usual (the whole air conditioner is automatically turned on at 24 ℃, and the power loss condition of SOC is not less than 15%), after long-distance driving under various road conditions (70% of urban expressways and 30% of urban roads), whether it is Qin L DM-i or Seal 06 DM-i, the true fuel consumption of 100 km feed is within the calibration range given by the manufacturer.
Not only that, this is completely lower than the fuel consumption level of the 3L/100km, and can even give a huge downfall to the Toyota model, which plays the HEV well.
To investigate the reason, I think this is nothing more than due to the fact that the fifth generation DM technology insists on using the electric-based power architecture, full-temperature vehicle thermal management architecture and intelligent electric integrated electronic and electrical architecture, while optimizing the details of each subsystem in the iterative process.
Especially in the engine, thermal management system, batteries and other core components, BYD’s technology improvement is very obvious.
First of all, unlike add-on hybrid cars, a good plug-in hybrid model must have high requirements for the engine.
The excellent degree of its performance often determines how to strike a balance between vehicle power and energy saving.
Therefore, although the new 1.
5L plug-in engine, as the main body of the fifth generation DM technology, is still a naturally aspirated engine, after technical optimization by BYD, despite the fact that the maximum power of the engine is in 74kw, its compression ratio has increased from 15.
5 to 16, and the highest thermal efficiency has reached 46.06%. What is the level of this data in the industry? As a reference, the 41% thermal efficiency of the 2.
0L Atkinson cycle engine used in Toyota’s fifth-generation THS hybrid system is already prominent in the market.
Although optimizing the thermal efficiency of each engine will probably go through the process of optimizing the combustion system, cooling system, lubrication system and ignition system, for a small displacement naturally aspirated engine, a significant improvement in thermal efficiency is necessary for power performance and energy consumption control.
By the same token, BYD uses a similar optimization method for the matching EHS electric mixing technology.
The volume of the new generation drive motor is designed to be smaller, and then the axial length is compressed.
Under this series of operations, the motor speed has increased, the working efficiency of the EHS electric mixing system has directly increased from 87.
6% to 92%, and the power density has increased by 70.28%. Of course, in the field of industrial design, any optimization change in design has always affected the whole body.
When the maximum speed of the new motor reaches 18000r/min, it is bound to generate more heat when it is working.
Well, in order to solve this problem, BYD has added an electronic oil pump to the new motor to carry out coordinated intelligent oil control cooling according to the working conditions and the electronic pump.
At the same time, in view of the fact that the motor adopts the design of ultra-thin silicon steel sheet and sectional magnetic steel, the noise of the whole machine is also further controlled.
As for batteries, the fifth generation DM technology uses a new generation of plug-in special blade batteries.
BYD’s engineering team not only optimized the battery structure, but also increased the energy density of the battery by 15.
9% and the discharge rate by 33% over the previous generation.
More importantly, BYD has also made a deep upgrade to the battery thermal management system this time.
Remember, when the blade battery was released, BYD equipped it with direct cooling technology, but today, the new direct cooling system actually further turns electricity.
The temperature difference within the core is reduced.
In particular, the cooling plate changed from a T-shaped channel to an S-shaped channel can directly control the degree of performance attenuation within a small range, thus ensuring the energy-saving effect of the entire vehicle under high and low temperatures.
Finally, due to the new electronic and electrical architecture, the fifth-generation DM technology integrates the industry’s first plug-in hybrid seven-in-one power domain controller, achieving efficient reuse of functions and increasing power density by 18.3%., In addition, the industry’s first chip integration technology realizes the three-in-one design of VCU (voltage control unit) and dual MCU (motor control unit).
The chip computing power has increased by 146%, greatly improving the integration and performance of the vehicle.
, In fact, driven by technology, based on BYD’s research and development experience in the field of hybrid technology, it must be within everyone’s expectations that it is related to the evolution of DM technology one after another.
However, today, compared with the technical game, for any car company that still wants to expect widespread recognition before the market structure is reshaped, it is necessary to come up with a decent balance between how to cater to consumer demand and how to showcase its skills. plan. This is exactly the case with the fifth generation DM technology.
, As I write here, the article is coming to an end.
Finally, I want to say that this year’s market is particularly “rolling”, which everyone in this industry can clearly perceive.
Even at BYD, the rapid growth in sales must be the result of fully absorbing consumer demand.
However, it is precisely this market environment that makes it clear to the outside world that BYD has almost become a development template for the entire industry in the context of using technology to hunt the market.
After several years of iteration, the fifth-generation DM technology can use the current comprehensive level, allowing Qin LDM-i and Haibao 06DM-i to sell well as soon as they are launched.
This is the best proof.
Of course, the pressure on the existing market is always self-evident, but judging from the existing market trends, it is likely that new energy vehicles that are mixed will still increase their market share.
For BYD, this is an opportunity given by the times, but it also indicates that BYD has now entered a new stage of seeking positive self-development.
