In 2020, BYD Han was the first heavy car. This is a medium-sized car with a wheelbase close to three meters. After the whole picture was exposed on January 9, it was ready to go on the declaration list of the Ministry of Industry and Information Technology on January 14. At present, some information about this car is gradually revealed in rhythm. Let’s take you to learn more about this heavy model.
The following figure shows the Han EV and Han DM declared by BYD in the Ministry of Industry and Information Technology.
Based on the above appearance declaration drawing and other appearance information, we can find that:
1. Han series is BYD’s first time to adopt EV/DM front face with different shapes, EV adopts closed grille, and DM is similar to the current family dragon face;
2. The new car uses a hidden door handle, which can reduce the wind resistance. Through a series of measures including it, the wind resistance coefficient of EV models is only 0.23;
3. The camera can be seen below the rearview mirror and above the license plate frame, and the millimeter-wave radar can be seen at the front of the EV model. Considering the current configuration of BYD’s models, the new car will definitely be equipped with 360 panoramic images, ACC, AEB and other functions;
4. The new car can be equipped with two different styles of wheels, 45/50 R18 and 245/45 R19, with panoramic sunroof as standard.
There is only one rendering on the side, but it can also be seen that Han used a Sportback design style similar to Audi, that is, the slip-back design.
There are no official pictures of the interior, but we found the design and a spy photo.
About the interior:
1. The overall style of the interior is similar to that of 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 rhombic pattern on the door panel, leather seats, wood grain materials and piano baking paint technology, the interior decoration has added a sense of luxury;
3. The left and right air outlets and the air outlets in the central control area adopt matrix design, which has not appeared in other models of the family; Two steering wheels with flat bottom are used in the design, but the steering wheel of Song Pro is still used in spy photos, and it may be replaced with a new one in the design in the future;
4. The handle area is equipped with a "Wisdom Heart" assembly similar to Song Pro, but with fewer physical buttons; The interior gives a close-up of the audio, and we guess that the brand audio may be used in the future, and BYD has never had a brand audio before.
In terms of body size, Han EV and Han DM have the same size, with the length, width and height of 4980/1910/1495 mm and the wheelbase of 2920 mm respectively. Since medium and large cars are generally the positions of luxury brands, we speculate that Han will still compete with medium-sized cars, which we will talk about later.
The following figure is still the declaration information of the Ministry of Industry and Information Technology. We can see that:
1. Han is carryingLithium iron phosphate batteryObviously different from a large number of ternary lithium products on the market at present, it is reported that the cruising range of NEDC will exceed 600 km；;
2. Han EV declared two power types: single motor (163 kW) and double motor (163 kW before and 200 kW)2 after); This is also the first time BYD has used the front and rear dual motors in cars. Before that, Tang used the dual motors with an average of 180 kW.
3. The Han DM model is equipped with a hybrid system consisting of a 2.0T turbocharged engine and a permanent magnet synchronous motor, in which the maximum power of the engine is 141 kW and the maximum power of the motor is 180 kW.
■ three questions to understand IPB
Another highlight about Han is that it is equipped with Bosch "IPB Intelligent Integrated Brake System" for the first time. We have a preliminary understanding of this new technology through three simple questions:
One,What is IPB?
IPB is the abbreviation of integrated power brake, which means "integrated brake control system" in Chinese.
Second,What is the function of IPB?
IPB is actually a highly integrated electro-hydraulic braking solution of bosch’s iBooster and ESP systems. Function is the combination of the two.
First of all, the function and principle of its first "component" iBooster are as follows:The traditional vacuum-assisted braking mechanism is cancelled, and electronic braking is used to assist..It can realize the functions of driving mode selection, energy recovery and active braking.Want to know more, click here to review.
The regenerative braking rate of IPB can be greater than 86%; In urban conditions, it can be more than 90%, and basically it can be braked by motor in most cases. The wear of the brake disc and the brake pad can be reduced.
Followed by ESP, which is the body stability system, is actually a combination of electronic brake distribution system (EBD), ABS, traction control system (TCS) and vehicle dynamic control system (VD).
In addition, BYD and Bosch have developed a new function on the basis of IPB, CST, Comfort Stop and Comfortable Parking, which enables new drivers to achieve the same smooth and comfortable parking effect as old drivers as long as they pedal. Byd engineers use precise control of braking pressure to eliminate deceleration impact and digest the energy absorbed by suspension in advance, so that the whole parking process becomes smooth.
Third, why use IPB?
Because Han’s power is too fierce, it must be matched with an excellent braking system. Therefore, in the early stage of product definition, Han set two goals:
The braking response should be fast, and the response time TTL(Time To Lock) of the braking system should be less than ＜150ms；; The braking limit should be high, such as better lateral control when cornering.
Faced with this goal, BYD gave three key parts choices: the first IPB, the second Brebo caliper and the third high-performance tire.
IPB, which combines iBooster and ESP, can give consideration to both horizontal and vertical, driving force and braking force while reducing the volume, and give a solution with shorter response time and better comfort, which can "grab" Han’s strong power.
Because IPB technology is also more complicated, it can be an article of its own. Here, I will simply explain it to you, and it is good to understand what it is and what it does.
■ Two questions about blade batteries
Like IPB, "blade battery" is very popular these days, and some 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.
One,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".
In fact, as early as the BYD technology experience creation meeting at the end of 2019, the news of "super lithium iron phosphate battery" came out. According to the data released at that time and the mass production time, it should be today’s blade battery.
Second,What are the advantages of blade batteries?
BYD officials say this: "Blade battery" is 50% higher than the traditional iron battery in volume specific energy density, and has the characteristics of high safety and long life. And "Han" will be the world’s first model equipped with "blade battery", which is expected to be listed in June this year.
We found the information related to this patent on the national patent inquiry website. After reading the literature, we found that the blade battery has the following advantages:
1. There is no need to form a module, but the battery core directly becomes a PACK, just like CTP in Contemporary Amperex Technology Co., Limited;
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 shows 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 volume of batteries, the car can put down more batteries and improve the energy density.
One of the advantages of Ferrous lithium phosphate over ternary lithium 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 did not give up studying Ferrous lithium 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, the length, width and height of BYD Han are 4980/1910/1495 mm and the wheelbase is 2920 mm From the data, there are no pure electric/plug-in products of similar size on the market at present.
However, the fact that there are no competing products now does not mean that there will be no competing products in the future. Tucki P7 and Weimar 7 series will be launched in 2020, and the current price of domestic Model 3 is 290,000. There are also rumors that it will be reduced to 250,000-200,000.
Compare the core data of the above pure electric products:
At present, Weimar 7 series only gives information such as 700 km battery life, and other information is unknown, so it is not included in the table.
In this way, Tucki P7 gives a variety of power combinations, and the size is slightly larger than that of Han. If Han EV wants to be rigid, the starting price should not exceed 300,000.
▲ Tucki P7, with a length of 4880 mm, a wheelbase of 2998 mm and a drag coefficient of 0.236, is Han’s opponent in all aspects.
Look at Han DM. If we broaden our horizons a little, suppose consumers want to buy a medium-sized car with quality and face. The appearance of Han DM is really stable and suitable for IKEA, and there is no problem of endurance anxiety. Therefore, Han may compete with mainstream products such as Passat and Accord.
Referring to the Passat plug-in version, the main selling price is about 250,000, and the top matching price is 286,900. However, Han also has advantages in the fields of performance and size. Without the influence of brand power (assuming that Passat’s brand power is not affected by the collision test), can BYD’s strength be equal to the golden signboard of joint venture brand?
Referring to the domestic Borui GE, the price of the plug-in version is about 190,000-200,000, but the Chinese DM is superior to Borui GE in performance, size, design leadership and other aspects, so the pricing must be above this.
The real medium and large car market is dominated by products such as Audi A6L, BMW 5 Series and Mercedes-Benz E-Class, supplemented by niche and unique products such as Jaguar XFL. The price is generally over 400,000, and the wheelbase is over 3 meters. Basically, luxury brands are eligible to enter. It is a brand-new universe that domestic cars have never been involved in. I don’t think Han will set a strange high price to find trouble with these cars.
I have confidence in Han. BYD has not sold more than 300,000 products. The sales of Tang DM prove that domestic brands can climb the mountain of 200,000 and embark on the road of 300,000. 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, neither humble nor supercilious, so that the price and product strength can be balanced with each other, and the brand will be upward, so that consumers really want to buy.
■ State Review
A few days ago, we launched a poll on "Who is the most valuable new car to buy in 2020" on the "Electric State" WeChat WeChat official account, and BYD Han won 23% of the votes, which also proved that Han is really the top traffic. I hope that Hanergy will live up to expectations and achieve a prosperous generation of Han Dynasty.
