Rebirth 2004: I can make money by writing.

After Hao Qiang's version of "BJ Welcomes You" was released, it attracted widespread attention.

The female voice in the song is pleasant, light and refreshing.

Qiu Yuqing teased, "I thought you found some pretty girl to sing with you, but it turns out you sang with a changed voice. That's hilarious."

"Yeah, what do you think?" Hao Qiang chattered a few words, making Qiu Yuqing burst into laughter.

Qiu Yuqing continued to joke: “This doesn’t sound like the female voice you sing at all. You just said it too seductively. You can hear it if you listen carefully.

But you really can’t tell that the song is sung by a man.”

Hao Qiang smiled and said, "Well, actually I asked the beautiful girl to sing."

On the album, only his name was written as the singer, and no female name was written. Most netizens thought that a female chorus must have been invited, but during the promotion, it was noted that it was a male and female chorus by Hao Qiang.

For Hao Qiang, no matter what the story behind the song is, as long as consumers buy it, it is enough.

If a media reporter interviews him, he can directly answer that it is a chorus of beautiful women, which is harmless.

After the release of "BJ Welcomes You", Hao Qiang shifted his attention to the lithium battery production line.

Since his thinking ability improved, his efficiency in solving technical problems has greatly increased.

Recently, the lithium battery production line has made great progress. Most of the equipment has been installed and debugged, and small-scale production is expected to be tried in early October.

The lithium battery factory has been completed and the production line equipment is now being installed and debugged in an orderly manner.

From the project launch at the beginning of this year to now, the speed of progress has exceeded Hao Qiang's imagination.

If I hadn't personally supervised it, I would have taken many detours and it would probably have taken several years to reach the current progress.

In order to develop the production line, the cost of scrapped equipment alone exceeded one million yuan. If it were not for his review and approval, the waste would probably have increased several times.

Time flies, and it is already November 1st.

In Workshop No. 1 of Galaxy New Energy Company, Hao Qiang and Vice President Wang He stood beside the production line. Lin Yan and Jiang Ying also followed curiously to observe the batch trial operation of this new lithium battery production line.

Last month, the ternary lithium battery production line was installed and small-batch production began.

The energy density of this batch of trial products reached 150wh/kg, meeting the design requirements.

Within a month, multiple rounds of trial production were carried out, with a total production capacity of approximately 2000Wh, enough to equip 1660 electric motorcycles.

According to preliminary statistics, the unqualified rate of primary production of ternary lithium batteries is 2.31%.

Failure to meet the standards does not mean that it cannot be repaired and used, as long as it meets the standards after repair.

However, after being repaired, some batteries were still judged to be scrapped, with a scrap rate as high as 0.38%, far exceeding Hao Qiang's expected four sigma level of 0.00621%, not to mention the stringent six sigma standard of 3.4ppm.

Of course, the applicability of Sigma Law varies for products in different industries.

Hao Qiang checked these scrapped batteries and found that the biggest problems were battery bulging and leakage.

But it is indeed quite difficult to thoroughly investigate the root cause. He can only check while production is in progress and rectify each problem he finds.

In addition, Hao Qiang requested that about 500 battery sets be selected from the qualified products and installed on F1 and F2 models for road tests, and at the same time the production line be optimized and transformed.

During the test drive phase, Hao Qiang rode his own F1 electric car to and from get off work and to campus. The students of CUHK were very surprised to see him riding an electric car instead of driving a luxury car or a Rolls-Royce.

Later everyone found out that Hao Qiang was personally testing the company's new products.

Seeing the boss’s dedication, other management members also joined in the experience.

After several rounds of optimization, the one-time production failure rate has been reduced to 0.22%, and the scrap rate has been controlled at 0.082%, but it still does not meet Hao Qiang's strict requirements.

However, the current level is sufficient for mass production, and in the future we will only need to continue to optimize and improve while production continues.

If we want to achieve the 6210ppm Six Sigma standard before mass production, it may take several years to meet the requirements.

The current pass rate is close to the three sigma level, which is acceptable.

Batch production lasted for over two hours, and there were no major problems. However, Hao Qiang noticed some issues and told Wang He, "The metal impurities in the positive electrode, after the charging reaction, also penetrate the diaphragm, forming black spots on the diaphragm and causing physical micro-short circuits. We need to solve the problem of nickel, cobalt and manganese metal purity from the source of the raw materials..."

Hao Qiang put forward many speculations, which could only be checked one by one.

"In addition, some customized equipment also has defects, which is an important reason for the low pass rate."

Wang He responded solemnly: "Okay, I will test samples of different purities to observe the impact of metal impurities..."

Hao Qiang was communicating with Wang He. Lin Yan heard some of what they were saying, but he just couldn't understand. He secretly sighed that his boss really knew everything.

Well, he was the one who led the development of the lithium battery production line.

A 20-year-old lithium battery expert, no one would believe it if they told him.

After half a day of inspection, Hao Qiang issued the order for formal mass production.

"Mr. Lin, after the ternary lithium battery has been tested for a period of time, if there are no problems, it can be put on the market. We have been delaying it for a long time." Hao Qiang explained.

The cost of ternary lithium batteries is much higher than that of lead-acid batteries, which means that the price of electric vehicles equipped with them will also increase.

Taking a 60V20Ah battery as an example, the purchase cost of a lead-acid battery is about 500 yuan, and the factory price is 700 yuan;

For the ternary lithium battery of the same capacity, the company calculated the comprehensive cost to be 700 yuan, the factory price was 1000 yuan, and the market price was 1300 yuan.

In other words, the original factory price of the F1 was 2900 yuan and the market price was 3500 yuan. After using the ternary lithium battery, the factory price must reach more than 3400 yuan and the market price must reach more than 4100 yuan.

Hao Qiang plans to set the factory price at 3600 yuan and the sales price at 4299 yuan.

In this way, the motorcycle company's gross profit will increase from 900 yuan to 1100 yuan in the future, and the terminal sales gross profit will increase by 100 yuan.

At the same time, Xinghe New Energy Company can have a gross profit of 300 yuan.

In the future, if the energy density of ternary lithium batteries is improved and production technology is optimized, the overall cost of 60V20Ah batteries will drop significantly.

Although the use of lithium batteries makes the F1 model a few hundred yuan more expensive, the battery weight is reduced by nearly 27 kilograms, the range is increased by nearly 20 kilometers, and the battery life is extended.

目前60V20Ah三元锂电池重8公斤，如果能量密度提高到270Wh/kg，重量仅4.5公斤左右。

The use of lithium batteries will greatly improve the convenience of the F2 model for female users.

Lin Yan said with anticipation: "Okay, Chairman, I believe many customers will like the new battery."

"That may not be the case. Price factors have a huge impact. Even if the product is good, some consumers are unwilling to spend hundreds of yuan more." Hao Qiang was a little worried.

"Well, you have a point."

"But let's try to launch it first. After all, we are positioned at the high end, and consumers may be willing to pay for it." Hao Qiang ordered, and decided to officially launch the lithium battery version of the car for sale.

Each model will be available in lead-acid and lithium battery versions, allowing consumers to choose.

He certainly hopes that consumers will choose ternary lithium batteries, which will help promote the company's lithium battery development.

At the same time, Hao Qiang earned more.

As long as the energy density is improved, the comprehensive cost of ternary lithium batteries can be reduced to about 400 yuan, which is cheaper than purchasing lead-acid batteries.

If the price of F1 is still 3999 yuan, the gross profit will increase from 1100 yuan to 1400 yuan, which is completely different.

"Okay, Chairman." Lin Yan is looking forward to the launch of the lithium-ion battery version of the car.
