Chapter 1472 Live Test!

After Lin Yu announced that there would be a live test, the popularity of the livestream room soared again.

In any case, the words "live test" immediately filled the press conference with entertainment value.

Whether the live test was a success or a complete failure, it was bound to generate a lot of buzz!

For fans and haters of Shenhua and Strafer Motors alike, this was a rare opportunity.

The screen switched to the test site, starting with needle penetration and crushing tests at Strafer Motors' battery research center.

In the needle penetration test, the results of needle penetration tests on three types of power batteries were compared: ternary lithium batteries burned violently during the needle penetration process, with a surface temperature exceeding 500 degrees; lithium iron phosphate batteries produced no open flame but emitted smoke during the penetration process, with a surface temperature of 200-400 degrees; while the blade battery produced no open flame or smoke, with a surface temperature of 30-60 degrees!

Next was the crushing test. A whole blade battery pack was removed from a K1 prototype on site. The PDU power distribution box on the battery pack was removed and placed on the side for data collection and testing. Then, the 28 blade batteries protruding from the upper layer were removed, leaving only the 150 blade batteries in the lower part, forming a flat surface.

Afterward, this flat surface was placed in a depression on the road surface, and repeatedly crushed by a pure electric heavy truck equipped with counterweights, with a total weight of 46 tons!

Although the lens showed that the surface of the battery had a slight depression and recovery process during the rolling, the battery pack was still intact when observed at close range after the pure electric heavy truck drove away!

Of course, this "intact" means that its appearance was not damaged, but if you look closely, the top aluminum plate was still slightly deformed.

However, this deformation had no effect on the performance of the battery cells. The test data showed that the single-cell voltage, total voltage, insulation resistance, and battery temperature were consistent with those before the test, with almost no change.

Immediately afterward, the on-site engineers put the blade battery back into the Jifeng K1. After it was installed, the car actually drove away successfully!

This test stunned all the viewers in the livestream room.

Because it was hard to believe that the blade battery could achieve this level!

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

The main reason was that other new energy vehicle manufacturers were too good at hyping, each boasting about their unique technology. The battery technology sector had already gone through several rounds of "bullshit competitions," and viewers were a little desensitized to hearing people brag about their battery technology.

Even though Strafer started with batteries, viewers were a little skeptical.

But the live test used intuitive images to force viewers to believe it!

In the past, one of the more concerning aspects of new energy vehicles was the unreliable stability of the batteries, which were prone to catching fire and spontaneously combusting in the event of a car accident.

Many small electric scooters use inferior ternary lithium batteries, which often catch fire and spontaneously combust, burning out in just a few seconds and posing a significant fire hazard. Even regular batteries can catch fire and spontaneously combust after a severe collision.

The danger may be relatively small when placed on electric scooters, as long as they don't spontaneously combust in the elevator, there's not much of a problem outdoors, and at least it usually doesn't lead to fatalities. But new energy vehicles are different. Once a collision occurs, the driver may be knocked unconscious and unable to escape in time, and the rapid fire of the battery may directly cremate the driver, all in one step.

There have been many cases abroad of electric vehicles catching fire and cremating the drivers after collisions. Although there are fewer such cases in China, they have happened.

If the battery problem is not solved, what's the point of doing well in the crash test for electric vehicles? The car shell can withstand the impact and absorb energy, but if the battery catches fire, isn't it all for nothing?

But after watching the needle penetration and crushing tests of the blade battery, all viewers had a very intuitive understanding of the battery's safety.

Coupled with Strafer Motors' consistently good reputation for collision safety, the safety of this Jifeng K1 became quite trustworthy.

The direction of the barrage had already changed somewhat.

"Awesome, the blade battery is simply crushing the ternary lithium battery! The improvement in safety is more important than anything else. It's not a big deal to drive a few dozen more kilometers, being able to save your life at a critical moment is the real deal!"

"Strafer's technology is indeed solid, there's no denying that. If it weren't for the weak brand power, it wouldn't have been priced so low."

"But the real test is only just beginning now. This test of the blade battery must have been done many times, and the conditions of each test are basically the same, so it can be guaranteed that there will be no problems, so the livestream didn't fail. But autonomous driving is different, the road conditions are different every time, what if the intelligent vehicle system suddenly has a program problem and freezes? It's hard to say."

"Maybe they'll send some people ahead of time to evacuate the vehicles and pedestrians on the road? It's too confident to just do an on-road test. If it were a prerecorded video, it would be fine, but a live failure can't be undone!"

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

Lin Yu did not blow his own horn for five minutes after one test was completed before moving on to the next test, as other manufacturers did, but directly entered the autonomous driving technology test phase.

"In order to allow everyone to see the effect of the autonomous driving technology more clearly and intuitively, we will turn off the voice assistant prompts during the test. Of course, if you become a Jifeng K1 owner in the future, I strongly recommend that you try Aeeis's AI voice package, which will definitely bring you different surprises."

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

"Hahaha, thank you, I've already experienced it! I've already smashed my keyboard, luckily I haven't bought the car yet, otherwise smashing the car would be a big loss!"

"Nonsense, I've been driving the K1 in the game for a long time, and now I'm calm and collected, and I'll never get angry on the road again."

Amid the banter of the barrage, the autonomous driving test officially began.

This livestream had three different camera positions: one was placed in the back seat of the vehicle, directly filming the steering wheel, center console screen, and the road ahead; another was a drone, hovering above the vehicle, a bit like a holographic image, filming the body and the road from above; and the last was arranged on the side of the road in some complex road sections, filming from an observer's perspective.

Soon, the tester drove to the test section and turned on autonomous driving.

Viewers immediately realized that the situation of this autonomous driving was exactly the same as in the game!

The main differences were two: first, the size of the center console screen in reality was slightly smaller than in the game, because the game is displayed with a monitor after all, and the field of view is small, but the actual viewing experience in reality should be similar to that in the game; second, there was no voice chattering, just pure driving.

This is also understandable, after all, if Aeeis were released, everyone's attention would be on Aeeis, and they would not pay attention to the performance of autonomous driving. The supporting character is just too good at stealing the show.

At the beginning, it was just very ordinary lane changes, lane keeping, following cars, etc. The safety officer didn't speak, and the road conditions were not complicated, so there was nothing to say. Other autonomous driving technologies can basically do it too.

But soon, the road conditions became complicated!

First, it completed an unprotected left turn, which caused the barrage to exclaim.

Because an unprotected left turn is a relatively difficult point to overcome in autonomous driving, it means that autonomous driving must be able to recognize traffic lights, recognize zebra crossings, pedestrians, and avoid straight-moving vehicles. If any link in this process fails, it will cause the failure of the unprotected left turn.

During autonomous driving, as long as the vehicle does not avoid the straight-moving vehicles in the distance, or does not successfully avoid pedestrians, the safety officer must intervene in driving as soon as possible, and then autonomous driving is declared a failure.

But the K1 was safe and smooth in completing the unprotected left turn. It not only accurately identified the traffic lights at the intersection and avoided straight-moving vehicles and pedestrians, but also remained smooth and steady throughout the driving process, giving people a calm and unhurried feeling.

But before the barrage had time to brush up on "awesome," the K1 had already arrived at an even more complicated road section.

The road itself was not wide, and there were also a row of cars and a large number of electric scooters parked on the side of the road. Many pedestrians and delivery guys riding bicycles and electric scooters shuttled back and forth, and even rode on the middle motor vehicle lane.

The cars on the opposite side were also squeezing this way, and sometimes in order to avoid pedestrians, they had to cross the center line and meet the other car in a very narrow road section.

The barrage was shocked.

"High energy ahead!"

"Damn, such a complicated road section? Are you crazy? Don't even mention autonomous driving, I feel my blood pressure rising when I drive myself!"

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

"It's completely at ease... Although autonomous driving reminded the driver to take over, the driver just ignored it, and it really passed!"

"I went, that delivery guy is crazy? An electric scooter overtakes from the blind spot on the right rear and then cuts in directly? If I were driving, I would have rolled down the window and cursed him!"

"Heh, so hurried, it's obvious that he's not a mō yú (lit. touching fish, slacking off) delivery guy. The mō yú delivery guys are all very calm."

"It can recognize pedestrian head pops, too awesome! And the big screen is indeed modeling in real time, cars, bicycles, and pedestrians can be accurately distinguished, and more dangerous ones will be marked in red, which is indeed clearer than people can see!"

"Yes, in fact, even if you don't turn on autonomous driving, just glancing at this center console screen from time to time can help with driving and better understand the road conditions!"

After passing through this complicated road section, the Jifeng K1 drove onto a road with relatively few vehicles, and the speed increased again.

In the case of complex urban road conditions throughout the entire journey, the Jifeng K1 spent a long time hovering at a speed of 10kmh, but when the road conditions allowed, it could reach a maximum of 50kmh.

This speed is already very fast compared to other autonomous driving models. Because autonomous driving must first ensure safety, other vehicles simply do not dare to drive so fast.

Although it is still slower than human driving, it must be said that the autonomous driving of the Jifeng K1 is safer, there will be no risky cutting in, and the acceleration and deceleration are very smooth, and there will be no sudden stepping on the accelerator or stepping on the brakes.

This is obviously more comfortable for the passengers in the car, and it is not easy to get motion sickness, which is a huge improvement in the riding experience!
