Horizontal knife immediately? Strong China characteristics.
Han is a rare special case in recent years in which the technical attention is higher than the model itself. People pay more attention to "blade batteries". This is indeed the most noteworthy place for Han.
Making batteries is definitely BYD's old line, and lithium ferrous phosphate is one of its specialties. As early as five or six years ago, BYD e6 got on NEDC with a battery pack with energy density of 1 17Wh/kg and total energy of 82kWh. In the highland of 400km, you should know that BAIC's ternary lithium electric vehicle was still hovering at 260km. Coupled with the better actual endurance performance of lithium ferrous phosphate, no one can compare with e6 except Tesla in running far.
Unfortunately, however, the development of lithium iron phosphate batteries soon encountered bottlenecks, while ternary lithium batteries made rapid progress. The forced market forced BYD to adopt ternary lithium batteries in the subsequent Dynasty series and E series models, and lithium ferrous phosphate only stuck to its position in the field of commercial vehicles that didn't care much about the size of battery packs.
However, Xueba is Xueba after all. After many years of dormancy, BYD showed his sword in one fell swoop and offered a blade battery. This way of de-modularizing makes the volume utilization rate of the whole battery pack increase by 50%, and the energy density of the battery pack exceeds 1.40 Wh/kg. Lithium ferrous phosphate again in the second spring.
On the Korean model, the most intuitive performance is as follows.
First, the car is easier to drive. With the improvement of energy density and the progress of group technology, the weight of the whole battery pack is greatly reduced. The feeling of dragging a lead pendant on the e6 car is gone forever. The handling, flexibility and braking stability of the whole vehicle have been greatly improved.
Second, the passability of cars is better. The volume utilization rate is improved, and the shape of the blade battery strip makes the whole battery pack thinner. The e6 chassis is punched off the ground, and the embarrassment of worrying about the bottom will be gone if you are not careful.
Third, the car runs farther. Korean EV is divided into two versions: long battery life and four-wheel drive high performance. NEDC has a battery life of 607km and 550km respectively. Breaking through the endurance level of 600km, although from the intuitive NEDC data, there is still a certain gap with most models using NCM8 1 1 ternary lithium batteries. However, considering the low cruising water content in lithium ferrous phosphate, if it is used in cities, it can basically reach more than 85% or even more than 90% of NEDC mileage, while lithium ternary can only reach 75%. Calculated, the actual cruising range is also on a horizontal line.
Yan value design? Break through again
As always? Dragon? Korean EV, the epitome of face design language, shows BYD's profound skills in design modeling. Although it is known as "Shuanglong Parallel Performance Aesthetics", in contrast, China DM really lacks a little flavor.
Without the large-size mesh air intake grille, the front face of Han EV is more complete and full, connecting the thick chrome trim strips of headlights on both sides, with a huge "Chinese" logo engraved in the middle. Different from the unique characters in its model, the left side of "Han" comes from the radical of "Sanshui Point" of Dazhuan, while the right side of "You" is a completely self-made word. Finally, a logo with easy recognition and strong memory is synthesized.
The same "Han" logo also appears on the hidden door handle, which is quite ceremonial at the moment when the handle pops out of the car body.
Han's interior has a good texture and is worthy of the price of more than 200 thousand. The air outlet of air conditioner is the place where designers show Chinese aesthetics. It is said that the inspiration comes from the Big Wild Goose Pagoda. This completely independent air guide mechanism is still rare on other models.
Liquid crystal display, 15 inch rotatable central control large screen, these are not available in the Han dynasty. There are various intelligent driving assistance systems. Di Piro has two parts: Didas and Di Trena. In addition to the driver assistance system that comes with the system, the coaching mode can also customize some auxiliary items according to the driving habits and behaviors of the owner.
Han's car system adopts BYD's latest DiLink? 3.0 Intelligent networking system provides many intelligent networking functions, including the perfect mapping of mobile phone functions. But I think the entertainment function can be found in the car, but safety should be the bottom line. Han's car system can dial king of fighters 97, and even support handle access, but the game is still going on when the car is driving, which is a bit out of line. Some people will say, "The system must have the function of automatically turning off videos or games when driving, right?" Yes, although I didn't read it carefully, this function definitely exists in theory. But you should know that in international brand cars, the front video will be turned off when driving, and there is no switch on. This is the sense of responsibility for safety. Independent brands can't meet the needs of consumers blindly, but they still have their own judgments and bottom lines.
Although we only got the long-lived version of the Korean EV, the dynamic performance of the vehicle is still good, especially in the middle section, with strong acceleration, sensitive braking system and no obvious brake nodding problem. It should be in order to better support the heavy body, the suspension system is set hard, and many subtle road bumps will be fed back to the car, lacking comfort.
The horizontal benchmark models of BYD Korea EV include Tucki P7 and Tesla Model3. Generally speaking, Han EV is more like. The layout of the buttons in the car keeps the convention of the fuel car, and there is even a start/stop switch, which is also related to its DM fuel version. Competing products have greatly simplified the physical buttons in the car. Except for the physical buttons on the steering wheel, almost all functions are completed by large-screen touch or voice control. These are also two different ways of thinking. Therefore, the sense of science and technology of Korean EV obviously lags behind the two competing products.
The advantages of Korean EV are more manifested in the leaf battery of lithium ferrous phosphate, after solving the problems of volume, energy density and charging efficiency. Blade battery brings us more accurate battery life calibration and more reliable battery safety, which is exactly what electric car owners need.
In my opinion, the most worthwhile thing to start with is Han EV? The entry-level model of 229,800 yuan, the actual cruising range of more than 500km, the wheelbase space of nearly 3m, excellent design and luxurious interior can all be obtained. On the other hand, it can be expected that blade batteries will be applied to other lower-end models in the future, which will bring great satisfaction in battery life. It is believed that with the lithium ferrous phosphate blade battery, BYD will surely usher in another wave of EV sales.
