NOVEL NEXT Chapter 92
The result of the first puncture test shocked everyone!
The expected burning, large amounts of smoke… and even explosion did not happen!
The solid-state ion battery in front of them was too stable! So stable that they could not believe it!
You know, their blade battery, which was specially designed for needle puncture tests and had enhanced safety, could not do this.
It still released a certain amount of heat during puncture, and a lot of smoke came out!
“Change position and continue puncture……”
Wang Chuanfu was a little bit unconvinced.
For the sake of rigor, he asked the two to change to a more tricky position.
This time, the alloy steel needle with a length of one meter was pulled out from the center of the battery pack.
Then he began to adjust the position.
The two engineers aimed at the upper left corner of the solid-state ion battery pack.
This part is the location of the built-in integrated chip management circuit of the entire battery pack.
Once damaged, the impact will be much greater than other places.
Thermal runaway will also come faster.
Sizzle!!
Another sound of metal penetration.
However, the result was no different from before.
The solid-state ion battery pack that was penetrated from bottom to top only emitted a wisp of light smoke, and then there was no movement again!!
“”It’s so stable! Incredible!”
Looking at the two large holes, all the senior R&D executives at BYD were stunned!
Hongqi really didn’t lie.
The super battery pack they produced not only has an incredibly high energy density, but also has world-class safety!
“Acupuncture test passed perfectly”
“Next, let’s try the squeeze experiment.……”
Wang Chuanfu stared at the solid-state ion battery and took a deep breath.
The executives and R&D personnel were stunned for a moment.
Then, they also took a deep breath!! 16 They knew in their hearts
“The highlight is coming!!
“The”extrusion test” can be said to be the most difficult problem to solve for new energy vehicle batteries at present.
Even car companies that claim to have high safety cannot guarantee that the battery pack will not experience thermal runaway and explosion under severe extrusion deformation.
If the needle puncture test is to pierce a hole in the entire battery pack.
Then the extrusion test is equivalent to forcibly using external force to squeeze the square battery pack into deformation, or even dent the entire battery pack and bend it completely, which is much more difficult than the former…
When a car is in a serious car accident.
The chassis is hit and squeezed by huge external forces. This is the case.
Once the battery pack explodes after a car accident, the life of the owner is in danger, and it may become a problem if it was nothing!
This is also a point that most people worry about.
Although serious car accidents are low-probability events.
But who can guarantee that they will not encounter them at all?
In order to avoid this situation, most new energy vehicle companies can only work hard on the strength of the car body and the protection of the battery pack embedded in the shell, and further strengthen it to avoid such extreme accidents.
“Come on!”
Two R&D engineers operated the machine with great caution.
They also wanted to see the limit of Hongqi’s”super battery pack”.
“The first step is to simulate chassis extrusion and intrusion 10%……”
As the words fell, a huge steel plate appeared on the side of the platform that fixed the battery pack, pushing in with great mechanical pressure.
The moment it touched the battery pack shell, an uncomfortable metal squeezing sound was heard.
The side of the entire solid-state ion battery pack was squeezed and deformed in an instant, but the area of this squeezing was just controlled at about 10% vertically.
The damaged battery pack continued to emit light smoke.
“Is it going to catch fire?
Everyone was extremely nervous! However
, the damaged battery pack only emitted a little smoke for a while.
Just like before, there was no further reaction!!
“Continue, simulate pressure%……”
Wang Chuanfu said.
BYD can also prevent spontaneous combustion if the compression is 10% to 20%.
But if the degree of damage is higher, it is completely unreliable.
The side compression area of the solid-state ion battery is increased again.
But the result is the same as before.
The two R&D engineers looked at each other and began to operate more boldly.
“30%……”
“40%……”
“50%……”
The degree of extrusion damage continued to increase.
Finally, when the extrusion damage area reached 60%, the entire solid-state ion battery was twisted and deformed beyond recognition, like a chocolate that was crushed by the squeeze. With a puff, a lot of thick smoke began to come out!!
“The heat is out of control!!”
“It’s burning……”
Everyone exclaimed!
As a large amount of smoke and the internal charge balance were destroyed, the internal heat began to be released crazily, and flames began to emerge from the squeezed and shattered cracks!
“”Okay, that’s enough!”
Wang Chuanfu called a halt.
The result of this experiment was too shocking!!
The safety of Hongqi’s solid-state ion battery reached an appalling level.
The entire battery pack was squeezed and damaged by 60% of its area before it began to burn due to thermal runaway.
You know, the battery packs of ordinary pure electric vehicles are laid on the chassis, and the front and rear sides are wrapped and protected to the greatest extent.
What does it mean that thermal runaway occurs only when the degree of squeezing damage reaches 60%?
Whether it is the front or the side, it is equivalent to crashing half of the car and the chassis. Those who can cause this degree of damage are extreme cases in extreme car accidents. In this case, the owner has no chance of survival, and there is no need to consider the problem of thermal runaway of the battery.
The faces of many BYD executives have become completely excited!!
With this battery pack,
BYD is fully confident to enter the high-end market.
“Boss, can we bring forward our high-end model plan?”(To read the exciting novels, go to Faloo Novel Network!)”
Vice President Zhao Longping couldn’t help but say.
BYD now occupies most of the market of hybrid pure electric vehicles below 200,000 yuan.
Before, there was a plan to impact the high-end market.
However, it was severely suppressed by pure electric giants such as Tesla and BBA, and there was no confidence to impact upwards.[]
It’s different now.
They have Hongqi’s solid-state ion battery, which has cleared the obstacles for pure electric vehicles to reach the high-end market.
Wang Chuanfu nodded. This is what he meant:
“No problem at all, and the sooner we promote it, the better, and follow the popularity of Hongqi on the Internet to rush to the high-end market.”
It has to be said.
As a domestic car company, Hongqi’s strong rise is also equivalent to an opportunity for domestic cars.
At least the recent online reputation of domestic brands will definitely be viewed with a new eye and will not be so contemptuous.
Before BYD, they were always labeled as taxis.
Although it is true that many people bought BYD to run Didi, in recent years, with the increase in sales and the change in user groups, this has become a bit”bad review”.
Even the most expensive BYD Han is called a”taxi”.
In short, according to the online water army’s attacking remarks, if you buy BYD, you are tied to running Didi!
It made many BYD executives’ noses crooked!!
…………
…………
The next day, the automotive section on the Internet was still immersed in the hot discussion of Hongqi.
As the Hongqi S9 started to be delivered in large quantities, many real Hongqi car owners shared their car picking experience online.
After waiting for more than a month, they finally picked up their”dream car”.
A post:
【Hongqi S9 car sharing, the real feeling of a land tank】
“Let me first say the conclusion: the product strength and cost-effectiveness are unbeatable, and it is full of black technology. It is completely worthy of the price of one million. You may even feel that buying this car for one million is a bargain!”
“Appearance: The Hongqi S9 is invincible and domineering. It is not inferior to the Range Rover and Cullinan in temperament. The real car is tall and mighty, and it also has a touch of traditional cultural elegance! (Photos)”
“Power: Full marks! The 2.6-second 0-100 acceleration is enough to beat ordinary supercars on the street!”
“Quietness: Full marks!”
“Seat comfort: As Hongqi’s first high-end car, I was a little worried at first, but in the end I found that this executive-oriented car is almost perfect in terms of comfort!!”
“Safety: I believe there is no need to say more about this aspect.……”

Reply below
“Damn, I’m crying with envy!!”
“Awesome! Congratulations to Brother Fu for picking up the car!!”
“Damn, we are just talking nonsense, do you really have the money to raise money?”
“In broad daylight, people are drooling with envy!!”
“I have to say, this car is really cool!!”
“Hongqi’s two models, a land tank and a land rocket, are both dream cars. I love them so much, but unfortunately I can’t afford them. It would be great if Hongqi could launch one or two models with a price of three or five hundred thousand, or if domestic cars could have one or two powerful models, that would be great too!!”
Although this car has the highest order volume of over one million.
But with such a large base, there are still only a few people who can spend one million to buy a car.
Most Chinese people only have a budget of 200,000 to 300,000 yuan for buying a car, and cars above 300,000 yuan are generally considered good cars.
Therefore.
Most people in the post were full of envy, saying that it would be great if Hongqi could launch another car with a lower price, or if domestic cars could have one or two powerful models, that would also be great.
Below this reply, someone else posted a reply
“Brother above, if you want to support domestic products, BYD seems to have just announced that it will launch a high-end pure electric model.” When this was said, the poster was stunned.
“What? BYD is also going high-end?!”837
“What is the price?”
“Starting at 300,000 yuan, I don’t know if it’s because of the red flag, BYD’s slogan this time is very explosive, it seems that it is very confident that it can break into this price range”
……
This post received a lot of views.
Many people immediately went online to watch.
BYD’s official account had already released a poster and slogan for a new high-end car.
【Opening a new era of domestic production, the new high-end pure electric brand Denza will help you shine in the future!! 】
On this poster, the outline of a mysterious car is looming.
BYD also took this opportunity to directly play the sub-brand card that it had prepared long ago.
Many people still pay attention to the BYD brand.
Of course, at this time, the most sensitive to the trend of domestic cars are still the joint venture car companies.
The price of 300,000 has already affected the interests of a number of luxury cars.
Tesla headquarters.
During this period,
Zhu Hua, the executive president of Tesla China, felt a sense of anxiety.
Two high-end flagship cars and the top supercars specially shipped from overseas were actually pressed to the ground by Hongqi!!
He almost vomited blood!
This has a huge impact on the image and tone of Tesla, a new energy brand.
The reputation of the world’s number one new energy vehicle brand has been shaken.
There is even public opinion that
Hongqi, a Chinese car company, has mastered more advanced three-electric technology than Tesla.
As soon as this”bad review” appeared on the Internet, he immediately had it removed!
Fortunately, although the Hongqi car company is currently in a strong momentum, it cannot affect their real interests.
In the price range of 200,000 to 400,000, Tesla’s sales are undoubtedly the new energy king!
“The two models”mode13″ and”modey”.
The monthly sales volume is 30,000 to 50,000, with an average price of 250,000-300,000 yuan and a gross profit margin of 32.9%, which is the source of Tesla’s real huge profits.
Even as a 300,000 yuan car, many places save materials to the extreme, and are praised as”unfinished houses”, it still does not affect its sales.
As long as he guards this market, the loss of high-end models is still acceptable, and Hongqi is unlikely to affect this market in such a short time, and they Tesla can still rest assured..
