"Let's go, let's get over too."

"Pack up your things."

As soon as the three academicians left the laboratory, Wang Fan followed closely and said to all the members.

Hearing this, the members nodded impatiently, and one by one they brought a small notebook and pen to record the content of the report.

Out of the lab.

Wang Fan did not rush to the venue as soon as possible, but waited at the door for a while.

About five or six minutes, Wang's father, who had just finished the exchange before the second round of consultation meetings, walked over with the management staff with a spring on his face.

"You guys go to the scene first, I'll be there later." Coming to Wang Fan, Wang's father waved his hand and motioned for the secretary and management personnel to rush over first.

"Dad, how does it feel to sit at the same table with these multinational giant presidents and chairmen? Tell us about your thoughts. Wang Fan asked with a smile.

Listening to Wang Fan's words, Wang Jun smiled, and then waved his hand:

"Actually, originally, I was quite curious, after all, these are all famous people all over the world, and they are all on the Forbes list, and they can only be seen on TV, the Internet or the news."

"But when I sat down at the table and talked to them, I realized that they were actually the same entrepreneurs I had met before."

"If you have to say that there is any difference between the two, it is nothing more than a matter of worth, and at a deeper level, it may be that the way of looking at things is different, and the rest is nothing."

When Wang Fan heard this, he immediately gave a thumbs up, this is his father's pattern.

No wonder it is a man who can pull a small workshop into a company with hundreds of millions of assets.

It's not simple.

"Go, go, go."

"Still laughing at your dad here." Listening to Wang Fan's words, Wang Jun said angrily, but the smile on his face was very useful.

The two exchanged pleasantries for a while, and then Dad Wang seemed to remember something and regained his seriousness:

"By the way, I almost forgot, there is something to tell you, just when the exchange was about to end, Tesla Mark's secretary specially pulled me aside and gave me a document."

"I said I wanted to hand it over to you, but I haven't opened it yet, you can take a look and see what it is, it's mysterious."

As he spoke, Dad Wang handed over a sealed document.

"Tesla?"

"How are they?"

Wang Fan was stunned for a moment, a little puzzled, and then asked:

"By the way, did they ask for anything when they gave this document?"

Dad Wang shook his head and denied: "He didn't say anything, his secretary just asked me to hand it over to you first, saying that you will know it when you read it." ”

Wang Fan directly opened the sealed document bag, took out the documents inside, glanced at it casually, and when he saw the title on the document, he was slightly surprised, closed the document again, and asked again:

"Dad, are you sure this is the technology given by Tesla?"

Wang Jun nodded, and replied in a very positive tone: "Yes, they gave it, can I still be wrong about this thing, I can guarantee that it was his secretary, it was Mark who signaled his secretary to come and talk to me, and took out this document." ”

"What's wrong?"

"Is there something wrong? What's inside the file? Wang Jun worried.

"It's not a problem, but it's a surprise."

Wang Fan said to himself, explaining to his father:

"Inside the sealed bag is Tsra's BMS."

“BMS？”

"What is this?" Dad Wang was not a new energy practitioner before, so he didn't know much about the technical names within these professions, so he could be said to be a real layman.

"Tesla's battery management system." Wang Fan opened his mouth again to explain.

"Tesla can be the world's first new energy vehicle company, in addition to its own battery materials are better than other car companies, and another very important thing is their management and use of batteries."

"To use a simple analogy, the same battery may be placed in their hands, and it can exert sixty or seventy percent of the effect, but in our domestic enterprises, only forty or fifty percent or even lower."

"An important role in this case is the BMS - battery management system, which can monitor the over-discharge, over-charge, SOC, SOD and temperature of the battery pack, so as to ensure that the entire battery pack is kept in an efficient operating state."

"It is this technology that makes the energy attenuation of their battery pack only 90% after running 300,000 kilometers, which is far from the level that domestic manufacturers are currently far behind."

Listening to Wang Fan's explanation, Wang's father also understood at once.

However, Wang's father soon had a new question: "If you say so, wouldn't this be equivalent to Tesla handing over their core technology?" Then they will ......... in the market later"

Wang Fan nodded and first answered Wang's father's first question:

"It's not necessarily the latest technology, it may be the batch of patents applied for in 11 years, but one thing is for sure, these technical materials are definitely the core of the past, and even now most Tesla cars are still being used."

"So I was a little surprised when I saw it just now, and I asked about it."

"In addition to that, I saw that this battery management system also includes TMS, which is their battery thermal management system."

"Thermal management system?"

Dad Wang is quite qualified as a manager, and he always takes the initiative to ask about things he doesn't know:

"Also a type of battery management system?"

"Yes, it's part of the management system."

"But when the industry talks about the two systems, they usually distinguish between them and don't confuse them."

Wang Fan further popularized science for his father.

"What's the difference?"

"The difference between the two may not sound like much, only one word, but the role of the latter can be said to be more than the former."

"The thermal management system is the key to the battery management system."

"At present, the industry's understanding of Tesla only knows that their thermal management system boldly adopts a serpentine thermally conductive aluminum tube coolant cooling system, in which water ethylene glycol ensures the freezing point at low temperatures, and then uses the efficient thermal conductivity of aluminum to conduct the heat generated by the battery pack into water glycol, so as to ensure rapid cooling of the battery and maintain the normal operation of the battery pack."

Wang Fan continued to flip through the documents and came to a conclusion.

"This is a complete, complete battery management system for Tsla."

"Then they gave this to us, this is ............"

"If I guessed correctly, Mark should want to use this technology as a requirement for more shares of silicon carbon anode material ion batteries."

Wang Fan didn't think about it, and almost instantly thought of the real answer behind it.

Actually, it's not hard to think.

What is Wang Fan's current concern for these multinational giants.

It is nothing more than a silicon carbon anode material ion battery.

But even so, he had to be surprised by Mark's magnanimity.

Regardless of whether this is Tesla's latest core technology or not.

However, as far as the one at hand is concerned, it is already the top in China.

It has considerable scientific research value.

"It's no wonder that this can be the world's No. 1 new energy company, and it's really different."

"At least this courage is something that no one else has."

Wang Fan sighed, and at the same time remembered some rumors about Mark in the market, especially his SpaceX and Starlink plans.

"This is a complete tech maniac."

Wang Fan commented again.

"Do we need to trade with them?"

Dad Wang asked one of the most important questions.

Wang Fan pondered for a while: "In this way, don't be in a hurry to answer them first." ”

"Hang it out."

"I'll ask the above first, I don't know if the above needs this technology."

"I'll make plans after asking."

When the words fell, Wang Fan edited a message and sent it to Fang Tianlei.
