The picture below shows the Korean EV declared by BYD in the Ministry of Industry and Information Technology. With Han DM.
According to the above appearance statement diagram and other appearance information, we can find that:
1.？ Han series is the first time BYD has adopted EV/DM? Different front faces, EV? A closed grille is adopted, DM? It is similar to the current family dragon face;
2.？ The new car adopts a hidden door handle, which can reduce wind resistance. Through a series of measures including it, it makes? EV？ The drag coefficient of the model is only? 0.23;
3.？ You can see the cameras under the rearview mirror and above the license plate frame, EV? Millimeter wave radar can be seen in front of the model. Considering the configuration of BYD's current models, the new car will definitely be equipped? 360 panoramic image, ACC, AEB? And other functions;
4.？ New car 45/50 optional? R 18 and 245/45? R 19？ Two different styles of wheels are equipped with panoramic sunroof as standard.
There is only a rendering on the side, but it can also be seen that Han used something similar to Audi? Sportback？ Design style, that is, slip back design.
There is no official picture inside, but we found the design and a spy photo.
About the interior:
1.？ The overall style of the interior is similar to the current dynasty series, which is simple and scientific, and the rotating large screen and full LCD instrument will not be absent;
2.？ Through the diamond pattern at the door panel, leather seats, wood grain materials and piano painting process, the interior adds a sense of luxury;
3.？ The left and right air outlets and the air outlet in the central control area are designed in matrix, which has not appeared in other models of the family; ? The design uses two flat-bottomed steering wheels. Do you still use Song Pro for spy photos? The newly designed steering wheel may be replaced in the future;
4.？ Is the block equipped with Song Pro? Similar to "Smart Heart" component, but with fewer physical buttons; ? The interior gives a close-up of the audio, and we guess that brand audio may be used in the future. BYD has never had brand audio before.
In terms of body size, Han EV? And Han DM? Same size, same length, same width, same height? 4980/ 19 10/ 1495? Well, what is the wheelbase? 2920? Mm, in view of the fact that medium and large cars are generally the positions of luxury brands, we speculate that Han will still compete with medium-sized cars, and we will talk about it later.
The following figure is still the declaration information of the Ministry of Industry and Information Technology. We can see:
1.？ Korea is equipped with lithium iron phosphate battery, which is obviously different from a large number of ternary lithium products on the market at present. It is reported that NEDC's cruising range will exceed? 600? Kilometers;
2.？ Han EV? This single motor (163? KW) and dual motors (front? 163? KW, after that? 200? KW)2 power types; This is also the first time BYD has used front and rear dual motors in cars. Before Tang used the front and rear ordinary motors? 180? kW？ Double motors.
3.？ Han DM? The model is made of? 2.0T？ Turbocharged engine+permanent magnet synchronous motor hybrid power system, in which the maximum power of the engine is? 14 1? KW, what is the maximum power of the motor? 180? Kilowatt
■? Three questions. Understand? IPB
Another highlight about Han is that it is equipped with Bosch "IPB Intelligent Integrated Braking System" for the first time. Through three simple questions, we have a preliminary understanding of this new technology:
1. What is IPB?
IPB？ what's up Comprehensive? Power? Brake? Chinese abbreviation for "Integrated Brake Control System".
Second, IPB? What is the function of?
IPB？ It's actually Bosch's? iBooster？ And then what? ESP？ Highly integrated electro-hydraulic braking solution. Function is a combination of the two.
First of all, its first "component"? iBooster？ The function and principle are as follows: the traditional vacuum-assisted braking mechanism is cancelled and electronic braking assistance is adopted. It can realize the functions of driving mode selection, energy recovery, active braking and so on. Want to know more, click here to see.
IPB？ The regenerative braking rate can be greater than 86%; In urban areas, it can be more than 90%, and in most cases, it can be braked by motor. The wear of the brake disc and the brake pad can be reduced.
then what ESP，ESP？ It is a body stability system, actually a combination of electronic brake distribution system (EBD), ABS, traction control system (TCS) and vehicle dynamic control system (VD).
Besides, where are BYD and Bosch? IPB？ Developed a new function based on CST, Comfort? Stop, a comfortable parking function, allows new drivers to achieve the same smooth and comfortable parking effect as old drivers as long as they step on the accelerator. BYD engineers eliminated the deceleration impact by precisely controlling the braking pressure, digested the energy absorbed by the suspension in advance, and made the whole parking process smooth.
Third, why use it? IPB？
Because Han's strength is too fierce, it must be matched with an excellent braking system. Therefore, in the early stage of product definition, Han set two goals:
Fast braking response, braking system response time? TTL (time? Where to? Lock) to < <150 ms; ; ? The braking limit should be high, such as better lateral control when cornering.
Faced with such a goal, BYD gave the choice of three key components: the first IPB? The second is a Braber caliper, and the third is a high-performance tire.
And then what? IPB, will? iBooster？ And then what? ESP？ The integrated scheme can give consideration to the horizontal and vertical, driving force and braking force while reducing the volume, and give a scheme with shorter response time and better comfort, which can "grab" the strong power of South Korea.
Because? IPB？ The technology is also complicated, and it can be an article of its own. Here is a brief explanation for everyone, just understand what it is and what it does.
■? Two problems about blade electricity.
With what? IPB？ Similarly, "blade battery" is also very popular these days, and some people even think that its appearance has led to the daily limit of BYD's share price. So what is such a powerful thing? We still know through a few questions.
1. What is a blade battery?
Blade battery is a "super lithium iron phosphate battery" developed by BYD. We guess it is named because the single battery is thin and looks like a "blade".
Actually as early as? 20 19? At the BYD Technology Experience Creation Meeting at the end of the year, the news of "Super Lithium Iron Phosphate Battery" came out. According to the published data and mass production time at that time, it should be today's blade battery.
Second, what are the advantages of blade batteries?
BYD officials say this: "Blade battery" has better volume energy density than traditional iron battery? 50%, high safety and long service life. And "Han" will be the world's first model equipped with "blade battery", which is expected this year? 6? Listed in June.
We found the relevant information of this patent on the national patent inquiry website. After reading the literature, we found that the blade battery has the following advantages:
1.？ Without forming a module, the battery becomes directly? Bao, with Contemporary Ampere Technology Co., Ltd.? CTP？ Same;
2.？ Compared with the traditional iron battery, the volume specific energy density is increased by 50%;
3.？ Due to the good structural design, the heat dissipation performance is excellent.
The following figure is the explosion diagram of the battery pack shown in the patent (referring to the three-dimensional assembly diagram, not the battery explosion).
Then, by reducing the size of the battery, the car can put down more batteries and improve the energy density.
One advantage of lithium ferrous phosphate over lithium ternary is that it is safer; The second is the price, and the disadvantage of low energy density has been solved by the "blade" structure. In addition, BYD didn't give up studying lithium ferrous phosphate even when ternary lithium was hot, and the future of blade battery seems to be relatively clear.
■? Who is Han's opponent?
According to the information of the Ministry of Industry and Information Technology, what are the length, width and height of BYD Han? 4980/ 19 10/ 1495? Well, wheelbase? 2920? Mm, from the data point of view, there are no pure electric/plug-in products of similar size on the market at present.
However, the absence of competing products now does not mean that there will be no competing products in the future. Tucki's P7 and Weimar 7 series will be in? 2020? Launched in China and made in China? Models? 3? What's the current price? 29? Wan, there are also rumors that it will be reduced to? 25-20? Wan.
Compare the above core data of pure electric products:
At present, Weimar 7 series only gives? 700? km？ Information such as battery life is unknown, so it is not included in the table.
So, Tucki P7? A variety of power combinations are given, and the size is slightly larger than that of Han. If Han? EV should be positive, and the starting price should not exceed? 30? Wan.
Looking at Han DM again, if we broaden our horizons a little, suppose consumers want to buy a medium-sized car with quality and face, Han DM? The appearance is really stable, suitable for IKEA, and there is no problem of endurance anxiety. Therefore, Han may compete with mainstream products such as Passat and Accord.
Refer to Passat plug-in version, where is the main price? 25? About 10 thousand, top match? 28.69? Ten thousand yuan, but Han also has advantages in performance and size. Aside from the influence of brand power (assuming Passat's brand power has not been affected by the crash test), can BYD's strength rival the gold-lettered signboard of the joint venture brand?
Referring to the domestic Borui GE, what is the price of the hybrid version? 19-20? About 10 thousand, but Han DM? The higher level is obviously superior to Borregg in performance, size and design leadership, so the pricing must be above this.
The real medium and large car market is dominated by Audi A6L, BMW 5 Series, Mercedes-Benz E-Class and other products. Jaguar XFL? Supplemented by niche and unique products, the price is average? 40? More than 10 thousand, more than wheelbase? 3? Rice, which basically belongs to luxury brands, is a brand-new universe that domestic cars have never set foot in. I don't think Han will set a strange high price to bother these cars.
I have confidence in Han. BYD hasn't sold it yet? 30? More than ten thousand products, don DM? Sales prove that domestic brands can turn over? 20? Above the mountains, up? 30? Ten thousand roads. Of course, it also depends on which way BYD wants Han to go. If you want to build a luxury performance flagship, regardless of sales volume, you can set a slightly higher price to reflect brand strength and product strength; If you want to really take the volume, you might as well copy Tang's experience, be neither humble nor supercilious, so that the price and product strength can be balanced with each other, and the brand is upward, so that consumers really want to buy.
■? Bangping branch
A few days ago, we launched a "2020? Who bought the most valuable heavy new car in 2008? Byd Han won the vote. 23%? The proportion of votes also proves that Han is indeed the first in traffic. I hope that Hanergy will live up to expectations and achieve a prosperous generation of Han Dynasty.
