Chapter 199 Batteries and Cells

"Domestic new energy vehicles are mainly trams now?" Guo Yuan continued to ask.

Mr. Lei shook his head when he heard the words: "Don't think that the trams are very popular at this stage, but in fact there are still more hybrids.

Mr. Guo, you are from Bingzhou. Your Bingzhou is the first city in the country to replace new energy taxis. This kind of taxi is mainly for charging, but they are not complete trams, but hybrid electric vehicles.

The Tang DMI series currently promoted by BYD is also a hybrid electric vehicle. BYD internally refers to this technology as a super hybrid electric vehicle. "

Guo Yuan was a little surprised when he heard the words. He also knew that the most luxurious SUV on BYD's production line at this stage is the Tang series.

He always thought that this car was a pure electric car, but he didn't expect it to be a hybrid electric car.

Guo Yuan didn't know anything about super hybrid technology, but Mr. Lei must be clear about it because he entered the car manufacturing industry. He explained to Guo Yuan what a super hybrid electric car is.

"Mr. Guo, the so-called super hybrid technology appeared as early as 100 years ago.

This technology once competed with fuel vehicles for the market, but the batteries at that time were only lead-acid batteries, which were large in size and weight, and low in energy density, so they could not be popularized, and eventually lost to ordinary fuel vehicles.

After the 80s, battery technology advanced by leaps and bounds. The emergence of nickel-cadmium batteries and nickel-hydrogen batteries allowed Toyota and Honda in the island country to create two different models of hybrid technology based on this.

Toyota is a planetary gear, and Honda is an extended-range hybrid.

BYD's hybrid technology should be similar to Honda's extended-range hybrid. "

"Then what is the extended program hybrid?" Guo Yuan continued to ask.

"The so-called extended-range hybrid means that the motor drives the wheels, the motor is driven by the battery, and the power of the battery comes from an independent engine without a gearbox.

Mr. Guo, you should have driven a car too, right?Anyone who has driven a car knows that the fuel consumption of the car is not high at high speeds, and the opposite is true at low speeds. This is because the combustion efficiency is the highest when the engine speed is high.

The extended-range hybrid can keep the engine running at high speed, so it is very fuel-efficient, and because of the electric drive, the driving experience is also very good.

And Honda's hybrid can also make the engine directly intervene to provide kinetic energy at high speeds.

That's why I say that BYD's hybrid principle is similar to Honda's. "

After listening to Mr. Lei's words, Guo Yuan tentatively asked again: "Mr. Lei, won't Honda cause trouble for BYD because of this technology patent?"

"Haha! Mr. Guo is right. At the beginning, Xiaori cough cough! Honda did find trouble with BYD, but then BYD found a way to bypass this patent.

BYD deliberately uses a battery with a greater energy density. The battery alone can drive the car for 50-100 kilometers, which allows people to freely choose the kinetic energy mode.

Pure electricity is enough for this battery life when you go to work to buy groceries or travel nearby, but when you go out, you can use oil to generate electricity, and there is no "battery battery life worry" problem of pure electric vehicles.

Moreover, BYD's pure electric mode has a stronger battery life than Honda's pure electric mode. In terms of technology, BYD has a slight advantage, and Honda can't talk about it anymore. "

After listening to Mr. Lei's words, Guo Yuan suddenly realized that the so-called super hybrid electric vehicle, to put it bluntly, uses the extended-range hybrid technology to use electricity for short distances and oil for long distances.

Moreover, BYD has gone further in this technology than the inventor Daoguo, and Daoguo has no way to say more about the patent.

"Mr. Guo has heard so much, are you optimistic about the hybrid model?" Mr. Lu asked.

Guo Yuan only understands the principle of the hybrid model, but he is not clear about the market prospect.

Fortunately, Guo Yuan had a narration, and the voice of the narration sounded in his mind: 【Hybrid technology is indeed a very good new energy vehicle technology, but this technology is not so easy to realize. Anyone who knows a little about the principle can explain it clearly , but whether it can be built and done well is another matter. 】

Guo Yuan repeated the words of the narration.

Mr. Lei was calm on the surface when he heard the words, but in his heart he had a little admiration for Guo Yuan.

This young man's gaze is really vicious.

Just now Guo Yuan looked like he had never heard of hybrid technology at all. After listening to him explain the principle, Guo Yuan was able to make such an accurate judgment on the market prospect. There is something.

Mr. Lei sighed in his heart and said with a smile: "Mr. Guo is right, the essence of a fuel vehicle engine is to burn gasoline, and our country can't catch up with Western countries after decades.

If it weren't for the rise of electric vehicles, the domestic automobile manufacturing industry would probably remain at the bottom. If you want to overtake on a curve, it is better to use pure electric vehicles. "

"What do you think of BYD's battery?" Guo Yuan asked.

"BYD's batteries must be at the leading level in the world, and Tesla's use of them can explain a lot of problems."

"So Mr. Lei, if there is a battery twice as powerful as BYD's battery in the world, what impact will it have on the market?"

"Is Mr. Guo talking about a semi-solid lithium battery?" Mr. Lei asked tentatively.

"Mr. Lei, do you know?"

"Of course, semi-solid lithium batteries are now widely used in the military, and many military products are using semi-solid lithium batteries. The performance of this battery is about 1 to 1.5 times that of common batteries.

However, due to some technical problems, this kind of battery cannot be mass-produced at low cost. It is not worth the loss to use this kind of battery regardless of the cost.

So Mr. Guo, I think this kind of battery will not be popularized in a short period of time, and your assumption is not very valid.

Of course, regardless of all practical factors, if this kind of battery is popularized, the impact on BYD will not be too great.

Because BYD has the world's largest and most complete car battery production line, even if the technology of semi-solid lithium batteries succeeds, BYD can also stabilize its position through OEM.

Regardless of whether it is domestic or foreign capital, it will take at least five years to establish an automotive battery production line comparable in size to BYD. "

"Is it just a car battery? What about other batteries?" Guo Yuan continued to ask.

"There are too many OEMs for other batteries. Take our rice as an example. Before 1, the batteries for our first batch of mobile phone rice 2012 were produced by Huizhou Desay.

Later, the battery always experienced unstable voltage and restarted, and the rice was changed to Scud production 12 years later, and it has been until today.

Now more than 80% of rice mobile phones use batteries produced by Scud.

Mr. Guo, you are using our Mi 13. If you are interested, you can disassemble the phone. There is a high probability that the words "Scud is produced for Mi phone" are marked on the back of your phone battery. "

"That's it! Which company does Rice use for the cell phone battery?"

"We use LG's batteries." Mr. Lei replied.

"What about the iPhone?" Guo Yuan asked.

"For the iPhone, the battery manufacturers are mainly Desai, Sunwoda, and Simplo, and the battery supply is mainly from LG and ATL, and some models use Sony's batteries.

To be honest, Sony batteries are definitely the best on the market, but the cost is very high. Only the promax model of the iPhone uses Sony batteries, and the others are ATL and LG, but these two companies themselves are actually Does not produce batteries. "

"That is to say, if you want to make mobile phone batteries now, you need to buy batteries from LG, right?" Guo Yuan asked.

"Not necessarily. In addition to LG, ATL can also be chosen. ATL is also a leading company in the battery industry, but LG is cheaper than ATL, so we and the iPhone will use LG on a large scale."

"Then is it possible to make it yourself?" Guo Yuan asked.

"Of course it is possible. BYD can make power battery cells and 3C batteries. They can even continue to provide 3C batteries. The related technologies of batteries are their own research and breakthrough.

However, according to our internal data at Rice, except for certain types of mobile phones, 11% of mobile phone users change every year, 29% change every two years, and 41% change every three to four years. 12%, and a special 1% who have never changed their mobile phones.

Many cars will be driven for more than ten years, and the capacity of car batteries is many times that of mobile phone batteries. The needs of these two batteries are completely different.

The standard of power battery is much stricter than 3C, which is the consensus in the industry.

BYD batteries are famous for their "power lithium iron phosphate battery". The blade iron lithium released in 2020 represents the highest level of power iron lithium in the world. This is also the battery Tesla chose to use.

However, almost no manufacturers choose their mobile phone lithium batteries. "

After listening to Mr. Lei's words, Guo Yuan frowned and asked, "Mr. Lei, you mean that it is easy to make 3C batteries, but it is not so easy to make fine ones, right?"
