Technology overlord starts with new energy vehicles

Kyushu Automobile Factory, the time is fast, and a few more days have passed.

The company is operating normally, and Kyushu Suzaku's sales work is also done very well.

In a few days, the Kyushu Suzaku, which originally sold for 10 million units in the Huaxia market, was sold to an average of 23 million units.

The only pity is that these are all one-off deals.

World-renowned auto companies bought it for research, and at most they only sold forty or fifty units.

With Suzaku's current production capacity and the more than ten vehicles that were in stock last month, it will take about two months for all of them to be delivered.

Barely earn more than 22 million units, and the sales of dozens of units are only about one billion.

Kyushu Suzaku, the research and development cost is not even higher than that of Kyushu Taishan and Kyushu Dongting, and it is even said to be much lower.

They are all Kyushu Motors' integration of the existing top technologies, and the application of some laboratory technologies to develop the power to the maximum extent.

The research and development time spent is not long, and the main test is the resource integration ability, but only in this respect, because of the research and development personnel team, Kyushu Motors is definitely the top in the world.

But in terms of production cost, because some technologies have not been mass-produced, the price is slightly higher, reaching a total of more than 800,000!

All in all, it's a small profit.

In addition, Hengxin Battery Factory and Apple's battery supply are also being coordinated and negotiated.

For the lithium iron phosphate battery produced by Hengxin Battery Factory, Apple is naturally very greedy.

In a large conference room in Kyushu Automobile's office building, Nelson Bello, general manager of Apple's Huaguo region, and Feng Hao, president of Hengxin Battery Factory, are discussing battery supply issues.

On the conference table, Feng Hao handed over a few batteries that had been rushed out in the past two days to the other party for careful inspection.

These are several rectangular black batteries, which are built one-to-one according to the iPhone 4 mobile phone batteries sold today.

After Nelson Bello took over the battery, he handed a few pieces to the engineers who came behind him, and kept a piece for himself to examine carefully.

In terms of weight, it is a little bit heavier than the previous Apple mobile phone battery, but the difference will not be very big, it should be within two or three grams, and it will not have a big change in the center of gravity and texture of the overall mobile phone.

While the other party was checking, Feng Hao explained some data about this battery to the other party in detail.

"This is the battery manufactured by our Hengxin Battery Factory. You can compare it carefully."

"In terms of parameters, the size is exactly the same as the battery of the previous iPhone 4 mobile phone, the battery voltage is 3.8V, and the stable output of voltage and current is guaranteed.

In terms of power, it has been upgraded from your previous 1420mAh battery capacity to 3000mAh, which is more than twice the previous battery capacity. "

Generally speaking, mobile phone batteries mostly use polymer batteries, which means that they are soft-packed and have strong shape plasticity. The positive electrode material is cobalt-lithium. Compared with ordinary lithium iron phosphate batteries that do not contain precious metals, the capacity per unit volume is higher. .

However, Kyushu Automobile is not an ordinary battery production company.

Although the battery technology of Kyushu Motors focuses on the development of sodium-ion batteries, some technologies have the same goal by different routes and can also be used on lithium iron phosphate batteries.

In addition, in addition to the lack of R\u0026D personnel in Kyushu Motors in the early stage, after a large recruitment expansion, there is no shortage of R\u0026D personnel.

When developing sodium-ion batteries, a part of the workforce can also be allocated to update and iterate the existing lithium iron phosphate battery technology with new technologies.

This has led to the battery technology of today's Kyushu Automobile Factory, which far exceeds those battery suppliers at this time node.

Not on a level at all!

Listening to Feng Hao's introduction, including Nelson Bello and a group of Apple engineers behind him, there is no doubt.

After a brief inspection, nothing could be seen, Nelson put down the battery in his hand, and answered Feng Hao seriously.

"Mr. Feng, your company's production and manufacturing technology in lithium iron phosphate batteries is top-notch in the world!"

"Especially the second-generation and third-generation lithium iron phosphate batteries, the performance is far better, even better than ternary lithium, lithium manganese oxide, cobalt lithium and other batteries!"

It is not an exaggeration to say that the mass production technology of precious metal lithium batteries, which are more capable of accommodating electrons, is the best in the world.

Regarding the battery technology of this battery factory, they have done a lot of homework before Apple came, and have investigated the batteries equipped in low-speed electric vehicles and even Kyushu Dongting.

If the performance is not really much better than their original mobile phone batteries, and this new product will not be released until next year, they can't wait to come here to discuss battery supply.

Some engineers use the simple equipment in their hands to conduct a simple test on the battery.

Someone even took out an iPhone 4 mobile phone for the first time, and after disassembling it, replaced it with a battery from Hengxin Battery Factory for testing.

Seeing that this group of people are very interested in this battery.

Feng Hao smiled and continued.

"You guys are very discerning!"

"Our Kyushu Automobile Factory, which made its fortune with battery technology, has always paid great attention to the research and development and improvement of batteries.

Looking around the world today, there is no second battery supplier with the same volume and capacity.

At the same time, in terms of battery cycle performance, considering that it is used as a mobile phone battery, the capacity is not very large, and some people consume relatively more power when using it because of playing games and so on.

Let the mobile phone that can be used normally for a day only be able to play games for seven or eight hours.

There may be a situation where it needs to be charged twice a day, and it cannot be guaranteed that there will be no major attenuation for ten years like a low-speed electric vehicle.

But we can guarantee that the attenuation will not exceed 10% within three years. If it is used lightly, the battery will not have a large power attenuation for five or even ten years. "

When Feng Hao said this.

Nelson Bello, who was sitting across from him, frowned and interrupted.

"In the case of heavy use, can it be used for three years? It is enough, and even a little too much!"

"The replacement cycle of mobile phones is different from that of cars. There will be a major upgrade in about two years. Sometimes the cycle performance is too good, which is not a good thing, and it is not conducive to the sales of mobile phones."

After thinking about it, Nelson Bello went on to say: "If the next cooperation is reached, I wonder if you can let your company's R\u0026D personnel optimize the battery.

I think that the heavy use of mobile phones will not have a major attenuation within one and a half years. After that, the power will attenuate to less than 70%. Light use will also attenuate significantly for up to three years. "

After a short pause, Feng Hao nodded: "... There should be no major problems, but I can't guarantee success, I can only say that I will do my best."

Nielsen reiterated again: "If possible, please be sure to meet our request, we can pay part of the research and development costs."

"no problem!"

Only then did Nelson Bello smile.

After briefly chatting about the problem of battery attenuation, Feng Hao continued: "In addition to the cycle performance of the battery, we also have unique technology in terms of the high and low temperature resistance of the battery.

The third-generation lithium iron phosphate battery can guarantee that the battery capacity will not drop below 80% at minus 20 degrees.

And even if it is 80% of the battery capacity, it is still much higher than your original battery capacity. "

Nielsen said happily: "This is very good. In this way, in some colder regions, the sales and use of mobile phones will be liked by more people.

Our previous battery supplier could not guarantee the long-term discharge of the battery at minus 20 degrees. "

Feng Hao: "We pay great attention to the safety performance of the battery. This is the third generation lithium iron phosphate battery, and the safety performance can be guaranteed.

This battery cell is also the battery we use on Kyushu cars. From the first generation of lithium iron phosphate battery to the third generation of lithium iron phosphate battery today, there has not been a single accident caused by the battery in two years. accident.

Whether it's an ordinary acupuncture experiment, crushing or even throwing it into a fire, it won't explode! "

"Well, this point is also very important. Safety is an attribute that all commodities must have. Even guns can bring a sense of security to those who use them, and only then can they be loved by consumers!"
