Jiuzhou Automobile Factory, time passed quickly, and a few days passed.

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

Within a few days, Kyushu Suzaku, which was originally priced at 10 million units in the Chinese market, sold for an average of 23 million units.

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

The world's leading automobile companies bought it for research, but the sales volume was only forty or fifty units at most.

With the current production capacity of Suzaku, plus the more than ten vehicles in stock last month, all deliveries can be completed in about two months.

It barely makes more than 22 million yuan per unit, and the sales volume of dozens of units is only over 1 billion.

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

They are all Jiuzhou Automobile's integration of existing top technologies, application of some laboratory technologies, and development of power to the maximum extent.

The research and development time spent is not long, and the main test is the ability to integrate resources. But in this aspect, because of the team of R&D personnel, Kyushu Automobile is definitely the best in the world.

In terms of production costs, 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 was a small profit.

In addition, Hengxin Battery Factory and Apple are also coordinating and negotiating for battery supply.

Apple is naturally very coveted for the lithium iron phosphate batteries produced by Hengxin Battery Factory.

In a large conference room in the Jiuzhou Automotive office building, Nelson Bello, Apple's general manager for China, and Feng Hao, president of Hengxin Battery Factory, are discussing battery supply issues.

At the conference table, Feng Hao handed several batteries that had been worked on in the past two days to the other party for closer inspection.

These are several rectangular black batteries, made one to one according to the batteries of Apple's four mobile phones sold today.

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

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

While the other party was checking it, Feng Hao carefully explained some data about this battery to the person opposite.

"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, the battery voltage is 3.8V, and the voltage and current output are guaranteed to be stable.

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

Generally speaking, most mobile phone batteries 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, they have a higher capacity per unit volume. .

But unfortunately, Kyushu Automobile is not an ordinary battery production company.

Although Kyushu Automobile's battery technology focuses on the development of sodium-ion batteries, some technologies have the same goal but can also be used in lithium iron phosphate batteries.

In addition, in addition to the lack of R&D personnel at Kyushu Automobile in the early days, after a large expansion of recruitment, there is no shortage of R&D personnel.

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

This has led to the current battery technology of Jiuzhou Automobile Factory to far exceed that of battery suppliers at this point in time.

Not on the same level at all!

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

After a brief inspection, he couldn't see anything. Nelson put down the battery in his hand and answered Feng Hao seriously.

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

"Especially the second and third generation lithium iron phosphate batteries, their performance is even better, even better than ternary lithium, lithium manganate, cobalt lithium and other batteries!"

The performance of some inferior materials can surpass this era. The mass production technology of precious metal lithium batteries that can better accommodate electrons cannot be said to be the best in the world.

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

If it weren't for the fact that the performance of their original mobile phone batteries wasn't so much better, they wouldn't have been so eager to discuss battery supply when this new product won't be released until next year.

An engineer used a simple device to conduct a simple test on the battery.

Some people even took out an iPhone 4 for the first time, took it apart and 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 are very discerning!"

“Our Jiuzhou Automobile Factory started out with battery technology and has always attached great importance to the research and development and improvement of batteries.

Nowadays, if we look around the world, we cannot find a second battery supplier with the same size 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. Some people consume relatively much power when using it because of playing games and so on.

A mobile phone that could originally last a day under normal use can only be used for playing games for seven or eight hours.

There may be situations where it is necessary to charge twice a day, and it cannot be guaranteed that there will be no major degradation for ten years like low-speed electric vehicles.

But we can guarantee that the attenuation will not exceed 10% in three years. If it is used lightly, the battery will not experience major power attenuation in five or even ten years. "

When Feng Hao said this.

Nelson Bello, who was sitting opposite, frowned and interrupted.

"With heavy use, it can last for three years. It's enough, 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 is not conducive to the sales of mobile phones."

After thinking about it, Nelson Bello continued: "If the next cooperation is reached, I wonder if your company's R&D personnel can be allowed to optimize the battery.

I think that heavy use of a mobile phone will not cause significant degradation within one and a half years. After that, the battery power will decline to less than 70%, and light usage will also decline significantly for up to three years. "

After a slight pause, Feng Hao nodded: "... There shouldn't be any big problems, but I can't guarantee success. I can only say that I will do my best."

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

"no problem!"

Nelson Bello then smiled.

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

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

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

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

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

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

This battery is also the battery we use in Kyushu cars. From the first generation lithium iron phosphate battery to the current third generation lithium iron phosphate battery, in two years, there has not been a single battery-related accident. accident.

Whether it is an ordinary acupuncture experiment, crushing, or even throwing it into a fire, there will be no explosion! "

"Well, this is also very important. Safety is an attribute that all products must have. Even if it is a gun, it can bring a sense of security to the people who use it, so that it can be loved by consumers!"
