Episode 288

Tesla’s net profit from selling a single car is about three times that of Toyota. The prevailing analysis was that high profits would be achieved through a combination of revenue from providing software updates and an aggressive vehicle price increase strategy.

I knew this from Elon, but I turned to Sylvie to get some more confirmation.

“What is Tesla’s net profit per model series?”

“If we look at it specifically, the net profit per Tesla vehicle is estimated at around $7,000. Of course, this is a rough estimate, so it is not certain. Even at this moment, Chairman Musk’s various savings plans are being passed.”

Silveiro was none other than Tesla’s engineer. It was Musk’s recommendation that allowed them to attract the talented Silveiro.

‘I don’t know what Musk is thinking.’

Despite the awkwardness between us over Dogecoin, Musk didn’t take it out on me, instead telling me about various electric vehicle infrastructures and even recommended a few talented Tesla engineers to join him.

I thought this was what it was like to live as a businessman in America.

“hmm.”

“Toyota and Daimler follow, but when it comes to quarterly gross profit, it’s hard to compare them to Tesla.”

Silvi analyzed that Tesla’s high profits are generated from sales of software required for autonomous driving in addition to vehicle sales. They monetized wireless software updates using the Internet and provide updates such as autonomous driving, and receive monthly income from drivers.

It appears that raising vehicle prices based on confidence in being the world’s best electric vehicle company also contributed to the increase in net profits.

However, I do not like Musk’s policy.

‘The introduction of a monthly subscription fee for connectivity services is truly an innovation.’

The idea of ​​collecting membership fees by selling cars was something I couldn’t understand. I also wondered if they would provide the kind of after-sales service they did.

I knew better than anyone else how much domestic consumer backlash Korean cars were receiving, so I couldn’t do anything about it.

‘Because there is such a huge difference between the domestic and foreign versions.’

In the case of Korean cars, there were cases where the mid-priced models overseas were cheaper than the base models in Korea.

It’s nothing but consumer fraud.

The reason why my heart towards Korean automobiles has changed like this is entirely due to the arrogance of Vice Chairman Jeong In-seok.

“It is important to increase profitability as well as safety. Of course, to do this, I think we need to learn how Tesla makes profits. However, we need to increase safety even if it means taking a little less profit.”

“So, what you’re wondering about, Chairman, is the concern about electric vehicles exploding?”

“Yes.”

The electric car debate is not something that started yesterday or today. It is still going on, and especially once electric cars start to catch fire, they are unstoppable.

The driver is trapped and dies.

What’s even more absurd is that once water starts flowing, there are many cases where people die because the electric car’s doors won’t open.

I think that while the reason for driving a car is convenience, the desire to buy one only arises when it can be backed up by a level of safety.

“Tesla fires occur at a rate of one per 250 million miles. So, I think they’re pretty safe.”

Perhaps it was because I was proud of my work at Tesla. I responded to Silvi’s words with a face devoid of emotion.

“It’s just Tesla’s report. I don’t blindly believe it.”

According to global scientific journals, the results of a comparative analysis of the fire risk of electric vehicles and internal combustion engine vehicles concluded that electric vehicles are much safer than internal combustion engine vehicles. They also said that the fact that the two types of vehicles have a big difference in history should be taken into account. Considering that vehicle safety has been brought to the fore recently due to the GM recall incident, this statement seems to have some basis.

Even so, I was the owner of Mate Ka.

‘I find it disgusting that people are burning to death in cars I build.’

I may not be able to tolerate myself.

Even in the case of Korean automobiles, they put cheaper products into internal combustion engine vehicles just because they are a few thousand won cheaper, but I never thought of doing that.

“Well, that’s true. It’s true that the risk of electric vehicle fires is receiving a lot of attention, but it’s a misunderstanding to think that only electric vehicles have a fire risk. In fact, the fire risk of internal combustion engine vehicles using diesel or gasoline is 11 times higher than that of electric vehicles.”

I had no intention of caring about Silvi’s feelings whatsoever.

“Is there an alternative?”

“In order to reduce the risk of fire in the battery to zero, the best thing to do is to make the battery chemistry and cell structure safe.”

I saw Silvi’s gaze glance towards me.

“Thermal runaway is inevitable. It is a phenomenon in which the temperature rises rapidly due to abnormal movement or destruction, right?”

“You mean the fire broke out?”

“That’s right. Stress at the design stage starts with defective parts due to design errors. Manufacturing defects, installation negligence, and overuse also play a part, but ultimately, the off-gas from thermal runaway is the most dangerous. It is the gas emitted due to an abnormal reaction of the battery, and it is when flammable gas explodes.”

A deep sigh was heard from Silvi.

“Fire from a car crash is a problem, but fires can also start from manufacturing errors or from cells that were previously impacted when the battery is in a resting state after charging. Have you seen it, Boss? A perfectly good car suddenly burns out in the parking lot.”

“I saw it.”

Musk showed this on Facebook once before. It was a perfectly good electric car burning up, and funny enough, it was a Korean car.

“If a fire starts in a cell, it will never be extinguished until the cell in which the thermal runaway occurred is completely consumed.”

“Even if we use a fire extinguisher or water?”

“Of course, the best digestive medicine is water.”

“Preemptive blocking is necessary. Lithium-ion batteries are vulnerable, right?”

“Lithium-ion batteries are not the answer. Lithium-ion batteries are inherently susceptible to fire and explosion.”

Lithium-ion batteries are self-combusting, meaning they burn without being supplied with oxygen from outside.

It is a battery that produces electricity through a chemical reaction of lithium, and it is composed of a cathode made of lithium oxide, a cathode made of graphite, an electrolyte that acts as a passage for ions, and a separator made of synthetic resin such as PE. It is light and small in size, yet highly efficient and can be reused at least dozens of times, so it is used in almost all secondary battery markets such as mobile phones, laptops, and electric vehicles.

However, when thermal runaway occurs, lithium-ion batteries have the characteristic of not turning off easily.

This is because the electrolyte, which acts as a passage for electrons, must use a volatile solvent that is easily ignited. If a blocking phenomenon occurs inside the battery and the temperature suddenly rises, there is a risk of ignition, fire, or even explosion. In particular, lithium-ion batteries made in large quantities are more vulnerable to fire.

It is impossible to extinguish a fire with a regular powder fire extinguisher. The only way to extinguish it is to continuously spray water for several hours and block the oxygen supply, which is extremely difficult.

Even Tesla is preparing as much as possible for a task that it cannot solve. This was a destiny.

“The best suppression method to date is to cool the battery pack so that the thermal runaway does not spread to adjacent cells.”

“Then, wouldn’t it be possible to install a cooling device directly on the battery pack and inject it with water?”

“How did you know that?”

I tried to control my expression at the surprised look in Silvi’s eyes.

“As a consumer, this is only common sense.”

“Well, if you put a cooling device inside the battery pack and inject it with water, it could be effective. It would be like hitting the battery that hasn’t exploded yet and putting it out. However, if a thermal runaway occurs, the temperature can reach as high as 1,000 degrees. You mentioned preemptive blocking, but that’s very inefficient. You need to make an inlet so that the coolant can circulate throughout the pack, and to do that, you need a groundbreaking idea from the battery designer level.”

“Is it impossible? Looking at the recent case of a Korean car, there was a case where the battery management system did not work properly and the high voltage caused the car to burn down.”

“Well, that’s a bit of a rare phenomenon. I think you’re talking about the Ioniq 5, but this is a phenomenon that no electric vehicle can avoid.”

It was a difficult task.

In the case of electric vehicles that catch fire while stopped or running, the fire usually starts in one cell and spreads to the next cell, eventually spreading to the entire vehicle.

In the case of the EV6 alone, there were about 400 cells installed.

In other words, it’s like running with 400 risk factors.

Even Tesla has had its share of vehicle fires, including one in the United States.

“If you need to install highly explosive battery cells, time is the answer.”

“What does that mean?”

I hardened my expression.

“The focus should be on strengthening the safety assessment of Mate Kaman’s own batteries and improving the management system. International standards are being updated to ensure the safety of electric vehicle batteries, but these are just test evaluations. It is safe to say that there is currently no evaluation under abnormal conditions such as traffic accidents.”

“Boss, it looks like you’ve done a lot of research.”

Although it was Silvio’s way of speaking that was not kind, that was still Silvio’s original personality.

I have solidified the principles and reason that are overflowing in my eyes.

“It is impossible to prevent fires from occurring in the first place, and in order to secure the golden time for rescue and minimize damage, tests under abnormal conditions such as thermal runaway are necessary. In other words, in order to buy time for escape, the walls surrounding the cells must be made thicker, and the battery pack structure and vehicle passive safety must be continuously improved.”

“The boss is right.”

“We need to control the performance of batteries that are basically installed in electric vehicles to a near-perfect level. Even if the failure rate of electric vehicle batteries is significantly lower than that of regular cars, if a fire breaks out, the driver’s death is a foregone conclusion. So if we can’t make the risk of fire zero, we need to buy golden time.”

“How about strengthening the battery management system that comes standard in electric vehicles?”

“Of course. We need to strengthen and mandate the BMS function much more than it is now. In addition to the original purpose of battery management, let’s make it mandatory to add functions such as battery abnormality detection range and warning functions, and evacuation alarm functions in case of fire to our Mate Car.”

Every word I poured out so boldly was the truth.

Silvi’s eyes shook violently as she looked into those eyes.

“We need to improve the manual that consumers need to be careful about when using electric vehicles. In particular, accidents often occur during charging. For example, it would be better to lower the charging rate a little, even if it means losing some of the driving range on a single charge. This is because the risk of fire increases when charging as much as possible or when charging rapidly. Also, if a fire occurs, we must make it easy to open and close the electric vehicle manually. We must not repeat the problems of Korean automobiles and Tesla.”

“That’s right. The handles of electric cars are powered by electricity, after all. But that’s the biggest problem: the production cost will go up even more.”

“It doesn’t matter. We are a startup and a latecomer. Automobiles are ultimately directly related to life. Unlike investments like Mate Coin or Mate Alpha V, this is a matter directly related to life, so let’s thoroughly focus our innovation on safety.”

“The boss is really great.”

I’ve always been rational, but now my emotions are showing themselves.

Silvi stared at me in front of her with an expression that seemed more unfamiliar than ever.

“What are you talking about?”

Silvio clicked his tongue hard.

“Boss is a person who is more sincere to the consumers than Elon Musk. I originally had some prejudice against Boss, but now that doubt has been resolved. I will do my best to design safety in the future.”

I nodded and stared blankly at Silvi for a moment before asking a question.

“But what kind of preconceptions did you have?”

Silvio tilted his head for a moment, then shook his head.

“no.”

“I’m curious.”

“actually.”

Taking advantage of the slight confusion, Silvi slyly replied.

“I thought the boss was more money-crazy than Elon Musk.”

My mind was blown. What should I say next?

In the past, I would have ignored Silvi’s opinion on Elon Musk, but not anymore.

‘Just look at Dogecoin and you’ll get the answer.’

Elon Musk advocates innovation, but I could agree with Silvi’s statement that he at least indirectly encouraged Dogecoin to buy and then quietly pulled out when the decline came to realize profits.

I looked straight into Silvi’s eyes.

“It’s true that I’m crazy about money. But at least I’m going to live a life where I make money with substance.”

To put it briefly, as expected, Silvi spoke hesitantly.

“This means I have one more person to respect in my life.”

I don’t think I’m a person worthy of respect.

Vice Chairman Jeong In-seok waited anxiously.

After a while, Hayes, the capable secretary who serves Seong-in, appeared.

“You don’t have a prior engagement?”

“Yes, but I absolutely must see the Chairman.”

I could only say this.

But Hayes bowed his head deeply.

“Unfortunately, the Chairman has decided to go meet with Vice President Todd Young. He said he would be willing to meet with him again if we reschedule the next appointment.”

Vice Chairman Jeong In-seok bowed his head deeply, feeling as if he was being treated well.

As the person who will become the chairman of Korea Automobile, I cannot see Chairman Seo even for a moment because I do not have a prior engagement, even though I am the vice chairman of a global automobile company.

‘I brought this upon myself.’

As the stock price of Korean automobile companies begins to plummet, shareholders are pouring out criticism.

Nevertheless, Vice Chairman Jeong In-seok’s heart burned as he was unable to meet Chairman Seo.
