Chapter 1472 Live Broadcast Test!

After Lin Yu announced that he would conduct a live broadcast test, the popularity of the live broadcast room rose again.

Anyway, as soon as the words "live test" came out, the press conference was immediately full of program effects.

Whether it is a successful live test or a rollover in the live test, it will definitely be full of topics!

For the fans and sunspots of Shenhua and Steffer Motors, this is a once-in-a-lifetime opportunity.

The big screen switched to the test site. First, acupuncture tests and rolling tests were carried out in the battery R&D center of Steffer Motors.

In the acupuncture test, the acupuncture comparison results of three kinds of power batteries were made: 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 unidentified, smokeless, and the surface temperature is 30~60 degrees!

Followed by the rolling test, the whole blade battery was removed from a K1 prototype car, and then the PDU distribution box on the battery pack was removed and placed on the side for data collection and testing. The 28 blade batteries that come out are removed, and only the lower 150 blade batteries are kept to form a plane.

Then, place this plane in a depression on the road, and use a pure electric heavy truck with a counterweight and a total weight of 46 tons to repeatedly crush it!

Although during the rolling process, the surface of the battery can be seen through the lens to be slightly dented and restored, but after the pure electric heavy truck is driven away, the battery pack is still intact!

Of course, this kind of intact means that its appearance is not damaged, but if you look closely, the aluminum plate on the top layer is still slightly deformed.

However, this deformation has no effect on the performance of the battery cell. It can be seen from the test data that the single-cell voltage, total voltage, insulation resistance and battery temperature of the battery are consistent with those before the test, and there is almost no change.

Immediately afterwards, the on-site engineer put the blade battery back on the Jifeng K1. After installing it, the car drove away successfully!

This test stunned the audience in the live broadcast room.

Because it is hard to believe that the blade battery can do this!

In fact, at the press conference, Lin Yu had already introduced the performance parameters of different batteries, but the response was relatively flat.

The main reason is that other new energy auto manufacturers are too good at bragging, and all of them boast that their own technology is unique. The battery technology has also gone through several rounds of "bragging competition", and the audience hears someone bragging about their own battery technology. , I don't have a cold anymore.

Even if Steffer started with batteries, the audience was a little bit unconvinced.

But the field test passed the intuitive picture, so that the audience had to believe it!

One of the more worrying things about new energy vehicles in the past is that the stability of the battery is not reliable, and it is easy to catch fire and spontaneous combustion in the event of a car accident or collision.

Many small battery cars use relatively inferior ternary lithium batteries, which often catch fire and spontaneously ignite, and burn out in just a few seconds, posing a major fire hazard. And even a regular battery will catch fire and spontaneously ignite after a violent collision.

It may be relatively less harmful to put it on a battery car. As long as it does not ignite spontaneously in the elevator, it will not be a big problem in the open air, at least generally it will not kill people. But new energy vehicles are different. Once a collision occurs, the owner may be knocked out and have no time to escape immediately, and the rapid fire of the battery may directly cremate the owner, all in one step.

There have been many cases of electric vehicles spontaneously igniting after crashing and cremating their owners in foreign countries. Although there are fewer cases in China, they have also happened.

If the battery problem is not resolved, what if the crash test of the electric car is done well? The car shell has withstood and absorbed energy, but if the battery burns up, isn’t it still free?

But after watching the needle test and rolling test of the blade battery, all the audience have a very intuitive understanding of the safety of this battery.

Coupled with Steffer Motors' good reputation for collision safety, the safety of this Jifeng K1 has become quite trustworthy.

The wind direction on the barrage has changed somewhat.

"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. It doesn't make much sense to run dozens of kilometers. It is serious to save your life at critical moments!"

"Steffer's technology is indeed excellent, and there is nothing wrong with it. If it weren't for the brand's strength, the price would not be so low."

"But the real test is only now beginning. The test of the blade battery must have been done many times. The conditions of each test are basically the same, and it can be guaranteed that there will be no problems. Therefore, there is no rollover in the live broadcast. But automatic driving is different. The road conditions of each test are different, what if the smart car machine system suddenly has a program problem and gets stuck? It’s hard to say.”

"Maybe some people will be dispatched in advance to evacuate the vehicles and pedestrians on the road? It's too confident to just go on the road for a test. If the recording and broadcasting are okay, there is no way to recover the rollover of the live broadcast!"

After the successful test of the blade battery, the audience's concerns shifted to Shenhua's autonomous driving technology.

Lin Yu didn't wait for five minutes after a test, like other manufacturers, before proceeding to the next test, but directly entered the test 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 you to try it. AEEIS' artificial intelligence voice package will definitely bring you different surprises."

Lin Yu's words caused bursts of laughter in the barrage.

"Hahaha, thank you, I have already experienced it! The keyboard has been smashed by me. Fortunately, I haven't bought a car, otherwise the loss will be huge if I smash the car!"

"Nonsense, I have been driving the K1 in the game for a long time, and now my mind is at peace, and I will never get angry again."

In the ridicule of the barrage, the test of automatic driving officially started.

There are three different camera positions for this live broadcast, one is placed in the back seat of the vehicle, directly shooting the steering wheel, the central control screen and the road ahead; the other is a drone, suspended in the upper room of the vehicle, which is a bit like a hologram The same, looking down on the car body and the road; the last one is arranged on the roadside of some complicated road sections, and is shot from the perspective of a bystander.

Soon, the tester drove to the test road section, and then turned on automatic driving.

The audience immediately discovered that the automatic 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 the game should be different from reality. It is similar; secondly, there is no voice in that BB, just driving.

This is also understandable. After all, when AEEIS is released, everyone’s attention will be on AEEIS, and they will no longer pay attention to the performance of automatic driving. The supporting role is really too good to steal the show.

At the beginning, it was just a very common lane change, lane change, car following, etc. The safety officer did not speak, and the road conditions were not complicated, so there was nothing to say, and other autonomous driving technologies can basically do it.

But soon, the road conditions became complicated!

First, he completed an unprotected left turn, which attracted the barrage of amazement.

Because unprotected left turning is a relatively difficult point in automatic driving, it means that automatic driving must be able to recognize traffic lights, zebra crossings, pedestrians, and avoid passing vehicles. Failure to protect the left turn.

During the automatic driving process, as long as the vehicle does not avoid the passing vehicles in the distance, or fails to avoid pedestrians, the safety officer must intervene in the driving at the first time, then the automatic driving will fail.

But K1 is safe and smooth in the process of completing the unprotected left turn. It not only accurately recognizes the traffic lights at the intersection, avoids straight vehicles and pedestrians, but also is always gentle and smooth during the driving process, giving people a sense of calmness. a feeling of.

But the barrage has not had time to be awesome, K1 has come to a more complicated section of the road.

The road itself is not spacious, and there are still a row of cars and a large number of battery cars parked on the side of the road. Many pedestrians on bicycles and battery cars or takeaway guys walk back and forth in it, and even ride on the motorway in the middle.

The cars on the opposite side are also squeezing this way. Sometimes in order to avoid pedestrians, they have to cross the center line and meet each other in very narrow roads.

The barrage was shocked.

"High energy ahead!"

"Fuck, such a complicated road section? Crazy? Let alone automatic driving, I can feel my blood pressure go up when I drive by myself!"

"Can you drive on this kind of road? And it's more stable than mine?"

"It's completely easy...Although the autopilot reminded the driver to take over, the driver just ignored it, and it really drove past!"

"I'm going, that delivery boy is crazy? A battery car overtakes another car from the blind spot from the right rear view and then directly blocks? If I drove, I would have rolled down the window and scolded him!"

"Heh, if you are in such a hurry, you don't look like the little brother who takes out Moyu. The little brothers who take out Moyu are very calm."

"Ghost probes can recognize ghosts, it's awesome! And 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, which is indeed easier to see than humans clear!"

"Yeah, in fact, even if you don't turn on the automatic driving, just glance at the central control screen occasionally, it can also be helpful for driving, and you can better grasp the road conditions!"

After crossing this complex road section, Jifeng K1 drove on a road section with relatively few vehicles, and the speed increased again.

In the case of complex urban road conditions throughout the whole process, Jifeng K1 hovers at a speed of 10KM/H for a long part of the time, but after the road conditions permit, it can drive up to 50KM/H.

Compared with other self-driving models, this speed is already very fast. Because automatic driving must first ensure safety, other vehicles dare not drive so fast.

Although it is still slower than human driving, it has to be said that Jifeng K1's automatic driving will be safer, and there will be no risky stoppage behavior, and the acceleration and deceleration are very smooth, without that sudden One foot on the accelerator or one foot on the brake.

This will obviously be more comfortable for the passengers in the car, and they will not be prone to motion sickness, which is a huge improvement in the riding experience!
