After Lin Yu announced that there would be a live broadcast of the test, the live-stream became even more popular.
The moment the words "live broadcast of the test" were mentioned, the news conference was immediately filled with the effect of a program.
Whether the test was a success or a failure, it would definitely be a hot topic!
To the fans and haters of Shenhua and Stefan, this was a once-in-a-lifetime opportunity.
The big screen switched to the test site. First, it was a needle prick test and a rolling test in Stefan's battery research and development center.
During the needle prick test, three types of power batteries were compared. The results showed that the ternary lithium battery burned violently during the needle prick process, and its surface temperature exceeded 500 degrees Celsius. The lithium iron phosphate battery had no flame during the puncture process, but there was smoke, and its surface temperature was 200 to 400 degrees Celsius. The blade battery had no flame, no smoke, and its surface temperature was 30 to 60 degrees Celsius!
Next was the rolling test. A blade battery was removed from a K1 prototype, and the PDU power distribution box was removed from the battery pack. It was placed at the side for data collection and testing. The 28 blade batteries that protruded from the top were removed, and only the 150 blade batteries at the bottom were left to form a flat surface.
After that, this flat surface was placed in a depression on the road, and a pure electric heavy truck with a total weight of 46 tons was repeatedly rolled over!
Although during the rolling process, the camera could see that the battery's surface was slightly dented and then recovered, after the pure electric heavy truck drove away, the battery pack was still intact when observed from a close distance!
Of course, this intact meant that there was no damage on the outside. However, if one looked closely, the aluminum plate on the top layer was slightly deformed.
This deformation did not affect the battery's performance at all. From the test data, it could be seen that the battery's voltage, total voltage, insulation resistance, and battery temperature were all the same as before the test. There were almost no changes.
Immediately after that, the engineers installed the blade battery back into the Jifeng K1. After the installation was done, the car was successfully driven away!
This test stunned all the viewers in the live streaming channel.
It was hard to believe that the blade battery could reach such a level!
Actually, during the news conference, Lin Yu had already introduced the performance parameters of different batteries, but the response was relatively dull.
It was mainly because the other alternative energy vehicle manufacturers were too good at bragging. All of them boasted that their technology was unique. The battery technology had also gone through several rounds of "bragging competitions". When the audience heard someone boasting about their battery technology, they were a little unimpressed.
Even though Steve had started his business with batteries, the audience didn't quite believe it.
However, the audience had no choice but to believe what they saw through the live test!
In the past, one of the more worrying things about new energy vehicles was the unreliability of the battery. Once a car accident occurred, it was easy for the battery to spontaneously combust.
Many small electric scooters would use inferior ternary lithium batteries, which would often spontaneously ignite. It would only take a few seconds for the battery to burn out, which was a major fire hazard. Even a regular battery would spontaneously combust after a violent collision.
Placing it on an electric scooter might be relatively less harmful. As long as it did not spontaneously combust in the elevator, it would not be a big problem if it was placed in the open. At least, it would not be fatal. But renewable energy vehicles were different. Once there was a collision, the owner might be knocked unconscious and unable to escape immediately. The rapid ignition of the battery could directly cremate the owner.
There had been many cases of electric scooters spontaneously combusting and cremating the owner after a collision. Although there were fewer cases in China, it had still happened.
If the battery problem was not solved, so what if the electric scooter did a good crash test? The shell of the scooter could withstand and absorb energy, but if the battery burned, wouldn't it be a waste?
However, after watching the needle test and crushing test of the Blade battery, all the audience had a very intuitive understanding of the safety of this battery.
Coupled with the good crash safety reputation of Steve's cars, the safety of the Blade K1 was quite trustworthy.
The wind direction of the bullet screen had changed a little.
"Amazing, the Blade battery is simply crushing compared to the ternary lithium battery! The safety improvement is more important than anything else. It doesn't make much sense to run a few more kilometers. It's more important to save your life at the critical moment! "
"Steve's technology is indeed excellent, there's no doubt about it. If it weren't for the brand, the price wouldn't be so low. "
"However, the real test has only begun. The Blade battery must have been tested many times. The conditions for each test are basically the same, so there will be no problems. That's why the live-stream did not fail. However, it's different for autonomous driving. The road conditions are different every time. What if the smart car system suddenly has a program problem and gets stuck? That's hard to say. "
"Maybe they'll send some people in advance to evacuate the vehicles and pedestrians on the road? They're too confident just to test it on the road. It's fine if it's recorded, but there's no way to salvage it if it fails in a live-stream! "
After the successful test of the Blade battery, the audience's worry shifted to Shenhua's autonomous driving technology.
Unlike other manufacturers, Lin Yu did not brag for five minutes after one test before moving on to the next. Instead, she went straight to the test of the autonomous driving technology.
"In order to let everyone see the effect of the autonomous driving technology more clearly and intuitively, we will turn off the voice assistant's prompts during the test. Of course, if everyone becomes the owner of the Blade K1 in the future, I strongly recommend that everyone try AEEIS's artificial intelligence voice package. It will definitely give everyone a different surprise. "
Lin Yu's words caused a burst of laughter in the bullet screen.
"Hahaha, thank you. I've already experienced it! I've already smashed the keyboard. Luckily, I haven't bought a car yet. Otherwise, I would have suffered a huge loss! "
"Nonsense. I've been driving the K1 in the game for a long time. My heart is as still as water now. I won't be angry anymore."
The autonomous driving test officially began as the bullet screen ridiculed them.
There were three different cameras in the live-stream this time. One was placed in the back seat of the car and directly filmed the steering wheel, the central control screen, and the road in front. The other was a drone that was suspended in the upper compartment of the car. It was a little like a holographic image, looking down at the car and the road. The last one was arranged at the roadside of some complicated roads and filmed from a bystander's point of view.
Soon, the tester drove to the test section and turned on the autonomous driving.
The audience immediately realized that the autonomous driving situation was exactly the same as in the game!
There were two main differences: First, the size of the central control screen in reality was slightly smaller than in the game. This was because the game was displayed using a monitor after all. The field of view was small. In fact, the actual look in reality and in the game should be similar. Second, there was no voice chattering. It was purely driving.
That was understandable. After all, everyone's attention would be focused on AEEIS once AEEIS was released. They would not pay attention to the performance of the autonomous driving. The supporting actors were too good at stealing the show.
At the beginning, it was very normal to change lines, change lanes, follow cars, and so on. The safety personnel did not say anything. The road conditions were not considered complicated, so there was nothing much to say. The other autonomous driving technologies could basically do it as well.
However, the road conditions soon became complicated!
First, it completed an unprotected left turn, causing the bullet screen to exclaim.
That was because unprotected left turns were relatively difficult to overcome in autonomous driving. It meant that the autonomous driving had to be able to recognize traffic lights, zebra crossings, pedestrians, and avoid straight cars. As long as there was a mistake in any of these, it would cause the unprotected left turn to fail.
During the process of autonomous driving, as long as the car did not avoid straight cars in the distance or did not successfully avoid pedestrians, the safety personnel would have to intervene immediately. Then, the autonomous driving would be declared a failure.
However, when K1 completed the unprotected left turn, it was safe and smooth. Not only did it accurately identify the traffic lights at the intersection and avoid the cars and pedestrians that were going straight, but it was also smooth and steady throughout the entire process. It gave off a feeling that it was calm and unruffled.
However, before the bullet screen comments could say anything awesome, K1 had already arrived at an even more complicated road.
The road itself was not considered spacious. There was a row of cars and a large number of electric scooters parked by the side of the road. Many pedestrians and delivery boys on bicycles and electric scooters passed back and forth. Some even rode to the middle lane.
The cars on the opposite side were also squeezing over. Sometimes, in order to avoid pedestrians, they had to cross the center line and meet the other car in a very narrow road.
The bullet screen comments were shocked.
"High energy ahead!"
"F * ck, such a complicated road? Are you crazy? Not to mention autonomous driving, I can feel my blood pressure rising even when I'm driving! "
"You can drive on such a road? And you're driving more steadily than I am? "
"You're doing it with ease … although the autonomous driving reminded the driver to take over, the driver ignored it and really drove over!"
"Holy sh * t, is that delivery boy crazy? An electric scooter overtook the car from the blind spot on the right rear and then accelerated? If I was driving, I would have rolled down the window and scolded him! "
"Heh, he's in such a hurry. One look and I can tell that he's not a delivery boy from Fish-Catching Take-Out. Fish-Catching Take-Out delivery delivery boys are all very calm. "
"He can even recognize ghosts; he's too awesome! What's more, the big screen is a real-time model. He can accurately distinguish between cars, bicycles, and pedestrians. The more dangerous ones are even marked in red. He can indeed see them more clearly than a human! "
"That's right. Actually, even if you don't turn on autonomous driving, you just have to glance at the central control screen occasionally to help drive. That way, you can better grasp the road conditions!"
After passing through this complicated road, the Jifeng K1 drove onto a road with relatively fewer cars, and its speed increased once again.
Due to the complex urban road conditions, the Jifeng K1 spent most of the time hovering around 10kmh. However, if the road conditions allowed it, it could go as high as 50kmh.
This speed was already very fast compared to other automatic driving vehicles. That was because automatic driving had to ensure safety first. Other cars would not dare to drive so fast.
Although it was still slower than a human driving, one had to admit that the Jifeng K1's automatic driving was safer. It would not take the risk of speeding up or overtaking the driver. What's more, the acceleration and deceleration were very smooth. There would not be any sudden stepping on the accelerator or the brakes.
This would obviously make the passengers in the car more comfortable. It would not be easy for them to get carsick. It was a huge improvement in the riding experience!
