After Lin Yu announced that he would conduct a live broadcast test, the popularity of the live broadcast room increased again.
Anyway, as soon as the words "live test" came out, the press conference was immediately full of program effects.
Whether the live test is successful or the live test crashes, it will definitely be full of topics!
For fans and fans of Shenhua and Stauffer Automobile, this is a once-in-a-lifetime opportunity.
The big screen switched to the test site. First, acupuncture tests and rolling tests were conducted at the battery R&D center of Stauffer Automotive.
In the acupuncture test, the acupuncture comparison results of three types of power batteries were done: the ternary lithium battery burned violently during the acupuncture process, and the surface temperature exceeded 500 degrees; the lithium iron phosphate battery had no open flame and smoke during the puncture process.
, the surface temperature is 200~400 degrees; while the blade battery is an unknown fire, smokeless, and the surface temperature is 30~60 degrees!
Next came the rolling test. A whole blade battery was removed from a K1 prototype car on site, and then the PDU distribution box on the battery pack was removed and placed on the side for data collection and testing. The upper convex
Remove the 28 blade batteries that come out, leaving only the 150 blade batteries in the lower part, forming a flat surface.
Then, this flat surface was placed in a depression in the road, and it was crushed repeatedly with a pure electric heavy-duty truck equipped with a counterweight, with a total weight of 46 tons!
Although during the rolling process, you can see through the lens the process of the battery surface being slightly dented and then recovering, but after the pure electric heavy truck drove away, a close inspection of the battery pack revealed that it was still intact!
Of course, this intact means that its appearance is not damaged, but if you look closely, the top aluminum plate is still slightly deformed.
However, this deformation has no impact on the performance of the battery core. It can be seen from the test data that the single cell voltage, total voltage, insulation resistance and battery temperature of the battery remain the same as before the test, with almost no changes.
Immediately afterwards, the on-site engineer installed the blade battery back on the Jifeng K1. After installation, the car drove away successfully!
This test shocked the audience in the live broadcast room.
Because it’s hard to believe that Blade Battery can actually do this!
In fact, at the press conference, Lin Yu had already introduced the performance parameters of different batteries, but the response was relatively lackluster.
The main reason is that other new energy vehicle manufacturers are too good at boasting, and each boasts that their own technology is unique. The battery technology has also gone through several rounds of "bragging competitions". When the audience hears someone bragging about their own battery technology,
I don’t have a cold anymore.
Even though Steffel started out with batteries, the audience still didn't believe it.
But through the intuitive pictures in the field test, the audience had no choice but to believe it!
In the past, one of the more worrying aspects of new energy vehicles was that the battery was unreliable and could easily catch fire in the event of a car accident.
Many small battery cars use relatively inferior ternary lithium batteries, which often catch fire and spontaneously ignite. They burn out in just a few seconds, posing a major fire hazard. And even regular batteries can burn out after a violent collision.
It will catch fire and ignite spontaneously.
Putting it on a battery car may be relatively less harmful. As long as you don't die and spontaneously combust in the elevator, it won't be a problem in the open air. But it is different with new energy vehicles. In the event of a collision, the owner may be knocked unconscious and will not be able to get to the first place in time.
Time escapes, and the rapid fire of the battery may directly spark the car owner, and it can be done in one step.
There have been many cases abroad where electric vehicles spontaneously ignited after crashes and the owners were cremated. Although it is less common in China, it has also happened.
If the battery problem is not solved, what if the electric car does well in the crash test? The car shell holds up and absorbs energy, but if the battery burns up, isn't it still in vain?
But after watching the acupuncture test and crushing test of the Blade Battery, all viewers had a very intuitive understanding of the safety of this battery.
Coupled with Stauffer Automobile's always good reputation for collision safety, the safety of this Jifeng K1 becomes quite trustworthy.
There have been some changes in the direction of the barrage.
"It's amazing. Compared with the ternary lithium battery, the blade battery is simply crushed! The improvement of safety is more important than anything else. Running for dozens of kilometers is of little significance. The most important thing is to be able to save your life at critical moments!"
"Stefer's technology is indeed excellent, and there's nothing wrong with that. If it weren't for the brand's push, the price wouldn't have been set so low."
"But the real test has only begun now. This test of Blade Battery must have been done many times. The conditions of each test are basically the same, which can ensure that there are no problems, so the live broadcast does not overturn. But autonomous driving is different. Every time
The road conditions in each test are different. What if the smart car system suddenly has a program problem and gets stuck? It’s hard to say.”
"Perhaps some people will be dispatched in advance to evacuate the vehicles and pedestrians on the road? It would be too confident to just go on the road for testing. If the recording and broadcast are okay, there is no way to recover the overturn during the live broadcast!"
After the successful test of the Blade Battery, the audience's concerns shifted to Shenhua's autonomous driving technology.
Lin Yu did not wait for five minutes after completing a test before entering the next test like other manufacturers, but directly entered the testing phase of autonomous driving technology.
"In order to allow everyone to see the effect of autonomous driving technology more clearly and intuitively, we will turn off the prompts of the voice assistant during the test. Of course, if you become the owner of Jifeng K1 in the future, I strongly recommend that you give it a try
AEEIS's artificial intelligence voice package will definitely bring different surprises to everyone."
Lin Yu's words caused a burst of laughter in the barrage.
"Hahaha, thank you, I have already experienced it! I have already smashed the keyboard. Fortunately, I haven't bought a car yet, otherwise the loss will be huge if the car is smashed!"
"Nonsense, I have been driving K1 in the game for a long time, and now I feel calm and will never be angry again."
Amid the ridicule on the barrage, the test of autonomous driving officially began.
This live broadcast has three different camera positions. One is placed in the back seat of the vehicle, directly filming the steering wheel, central control screen and the road ahead; the other is a drone, suspended in the upper room of the vehicle, a bit like a holographic image.
The same, overhead shots of the car body and the road; the last one is arranged on the side of the road in some complicated road sections, shooting from the perspective of a bystander.
Soon, the tester drove to the test road section and turned on autonomous driving.
The audience immediately discovered that this autonomous driving situation was exactly the same as in the game!
There are two main differences: first, the size of the central control screen in reality is slightly smaller than that in the game. This is because the game is displayed on a monitor after all, and the field of view is small. In fact, the actual look and feel in reality and in the game should be different.
It is similar; secondly, there is no voice on the BB, it is just driving.
This is understandable. After all, if AEEIS is released, everyone's attention will be on AEEIS and they will no longer pay attention to the performance of autonomous driving. The supporting roles are really stealing the show.
At the beginning, it was just common things like changing lanes, changing lanes, following cars, etc. The safety officer didn’t say anything, and the road conditions weren’t too complicated, so there wasn’t much to say. Other autonomous driving technologies can basically do it.
But soon, the road conditions became complicated!
First, he completed an unprotected left turn, which attracted a lot of admiration from the barrage.
Because unprotected left turns are a relatively difficult point to overcome in autonomous driving, it means that autonomous driving must be able to identify traffic lights, zebra crossings, pedestrians, and avoid straight-moving vehicles. If there is a mistake in any of these links, it will cause accidents.
Failure to protect left turns.
During the process of autonomous driving, as long as the vehicle fails to avoid distant vehicles traveling straight ahead, or fails to successfully avoid pedestrians, the safety officer must intervene in the driving immediately, and then the autonomous driving will fail.
However, K1 was safe and smooth in completing the unprotected left turn. Not only did it accurately identify the traffic lights at the intersection, it avoided straight-moving vehicles and pedestrians, it was also always gentle and smooth during the driving process, giving people a calm and unhurried feeling.
feeling.
But before the barrage could show off its awesomeness, K1 had already arrived at a more complicated road section.
The road itself is not very spacious, and there are a row of cars and a large number of battery-powered cars parked on the roadside. Many pedestrians on bicycles and battery-powered cars or takeaway guys are walking back and forth among them, and even riding on the motor vehicle lane in the middle.
The cars on the opposite side are also squeezing in this direction, and sometimes in order to avoid pedestrians, they have to cross the center line and meet the other car on a very narrow section of road.
The barrage was shocking.
"High energy ahead!"
"Fuck, such a complicated road section? Are you crazy? Let alone autonomous driving, my blood pressure rises even when I drive by myself!"
"Can you drive on this kind of road? And it's more stable than me?"
"It was completely smooth...Although the autonomous driving reminded the driver to take over, the driver just ignored it and actually drove past!"
"Let me go, is that takeaway guy crazy? A battery car overtook from the blind spot of the right rear view and then blocked the car? If I were driving, I would have rolled down the window and scolded him!"
"Haha, you are in such a hurry. It doesn't look like you are a Moyu takeout guy. Moyu takeout guys are all very calm."
"The ghost detector can recognize it, it's so awesome! Moreover, the big screen is indeed modeled in real time. Cars, bicycles and pedestrians can be accurately distinguished, and the more dangerous ones will be marked in red. It is indeed better than humans can see."
clear!"
"Yes, in fact, even if you don't drive autonomously, just occasionally glancing at this central control screen can be helpful to driving and help you better grasp the road conditions!"
After crossing this complicated road section, Jifeng K1 drove onto a road section with relatively few vehicles, and the speed increased again.
In the case of complex urban road conditions throughout the journey, Jifeng K1 hovered at 10KM/H for a long time, but when the road conditions allowed, it could drive up to 50KM/H.
Compared with other self-driving models, this speed is already very fast. Because self-driving must first ensure safety, other vehicles simply do not dare to drive so fast.
Although it is still slower than human driving, it has to be said that Ji Feng K1's autonomous driving will be safer, and there will be no risk of jumping into traffic, and the acceleration and deceleration will be very smooth, and there will not be any sudden
A foot on the accelerator or a foot on the brake.
This will obviously be more comfortable for the passengers in the car and will make them less prone to motion sickness.
