Rebirth 2004: I can make money by writing.

Over the next two days,

Hao Qiang examined the market price and performance of every component of the electric motorcycle in order to more accurately grasp the market situation of electric motorcycles.

他还亲自买了零配件，花了260元买一个800w电机，花750元买一组60v20ah铅酸电池。

Then he bought other spare parts.

包括后平叉50元、实心方向柱100元、减震一对100元、刹车线刹车把30元、前后轮挡泥板35元、后减震50元、二手后轮刹碟刹60元、车篮子15元、坐垫17元、控制器1500瓦100元、二手前轮总成80元以及其他杂项近百元……

The frame was second-hand, and he also bought a lot of tools such as a grinder and an electric drill and assembled it himself.

After a few days of hard work, the car was finally assembled.

Although this car looks a bit out of place, it performs well and is easy to drive.

But no matter what, after all this trouble, he has a clearer understanding of the market prices of electric motorcycle structural components, which provides a valuable reference for his future business decisions.

"Hey, they look good, but they're usually useless!"

Hao Qiang comforted himself and felt a sense of accomplishment.

When he happily rode the electric motorcycle he assembled himself into the campus, many students showed surprised expressions.

Someone asked curiously, "Boss Hao, where did you find this second-hand electric motorcycle?"

Hao Qiang smiled a little embarrassedly: "Actually, I pretended it myself."

"Only a ghost would believe you!"

"I don't believe it either, haha."

"He doesn't drive a good Porsche, but a shabby used car."

Hao Qiang smiled and said, the Porsche is just a second-hand car!

After walking around the campus, he rode his electric scooter back to his rental community.

Back at the rented house, Hao Qiang opened the writing system and the technology store.

He went straight for electric motorcycle frame technology.

No longer hesitate.

【Confirm the technology! 】

In an instant, a warm current rushed into Hao Qiang's brain, and a lot of relevant knowledge about electric motorcycle frames flowed into his mind like a trickle of water.

[Steel pipe material: No. 20 steel, welding method: double-container welding, welding materials: solid wire ER50-6 or equivalent grade welding materials, welding machine: 400A or 500A grade, welding current and voltage: see welding diagram for details...]

Including CAD drawings and 3D drawings of several new types of vehicle frames, he learned to read drawings in one go.

Awesome, you have knowledge of mechanical drawing.

For example, why is No. 20 steel used as the material for steel pipes? The main reason is that the carbon equivalent of this material is low, only about 0.20%, and in fact it is even lower than about 0.16%. Therefore, it has good welding performance and plasticity, and good plasticity makes it easy to cold bend.

Of course, the downside is that both the yield strength and tensile strength are low, with the yield strength being 245 MPa.

If No. 45 steel is used, the carbon equivalent is about 0.45%, and the welding performance is poor, that is, the weld is easy to fall off and the plasticity is not good, but the yield strength can reach more than 355 MPa.

Hao Qiang learned that welding performance is closely related to the carbon equivalent of the material, which feels quite mysterious.

He didn't know this knowledge before.

The frame is made of steel and is mainly made by welding. Hao Qiang has absorbed this technology and integrated a lot of related knowledge.

Of course, he can understand CAD drawings, but the system does not give him the actual operation skills of CAD, which is different from what he has learned so far.

Similarly, the system taught Hao Qiang some welding knowledge, but did not allow him to learn welding operations or how to compile specific welding processes. It just let him know that such a thing existed.

However, this is enough.

Relying on this basic knowledge, Hao Qiang can recruit relevant technical personnel, let mechanical design engineers draw the drawings, and let welding process engineers compile welding processes and guide production.

Now, he can understand CAD drawings, machining processes, welding processes, painting processes and other processes, and roughly know whether the frame design, process and production are reasonable.

It can be said that after integrating this technology, it is equivalent to being a motorcycle frame workshop director who has worked for many years.

Next, Hao Qiang chose charging technology.

After selecting these two technologies, the fourth area of ​​the third-level technology store was extended and expanded, with a lot more electric motorcycle technologies than the second-level technology store.

However, Hao Qiang has decided to choose the field of power battery technology.

After absorbing the charging technology, he then chose the manufacturing and process of ternary lithium batteries and lithium iron phosphate batteries.

Start merging.

[Knowledge about ternary lithium batteries, including solid-phase method, battery packs, energy density improvement technology, electrolyte ratio and manufacturing, lithium ore and lithium clay, etc., also includes the design drawings, design specifications, calculation books, process data, etc. of the three types of battery packs, covering design drawings, production and process]

Under mass production conditions, the technical level of mass energy density of ternary lithium battery cells has reached 150wh/kg!

By 2022, Ningde Era will be 220-300Wh/kg.

In comparison, there is a big difference.

However, in this day and age, achieving 150wh/kg in mass production is already very impressive, and the system evaluation is at the domestic first-class level. Hao Qiang believes that it has reached the top level in the country, which makes him a little surprised.

Of course, this is because there are no competitors in the ternary lithium industry at this time.

If Hao Qiang's ternary lithium battery technology remains stagnant in more than a decade, it will not even be considered domestically first-class.

In addition, compared with other batteries, ternary lithium batteries are a wasteland, and the number of related patents is relatively small. Hao Qiang does not have to worry so much when applying for patents in this area of ​​research and development.

Otherwise, the patent coverage issue will cause him a headache, and similarly, it will also cause headaches for his competitors.

Next, Hao Qiang integrated lithium iron phosphate battery technology, and the single cell energy density reached 90Wh/kg.

Hao Qiang estimates that his technical level will not be much different from that of Biyadi at this time.

BYD has been focusing on lithium iron phosphate batteries and is at the leading level in China in this field. In the future, the company will develop high-energy-density lithium iron phosphate batteries with an energy density of up to 150Wh/kg.

In 2002, BYD became NOKIA's first Chinese lithium-ion battery supplier; in May of the same year, it obtained QS-9000 certification.

Currently, the first new car F3 will roll off the production line in April this year.

In those years, people have been complaining about BYD cars, thinking they are rubbish.

Unexpectedly, more than a decade later, most of those who once complained about BYD are no longer able to afford its high-end models. Domestic cars are no longer a shame, but are gradually coming to the fore.

Hao Qiang currently has no experience in the battery industry, and it is impossible for him to compete with BYD.

His greatest advantage is that he knows the future development trends. If his development pace is too slow, then this advantage of foresight will disappear.

So, there is not much time left for him.

In 2008, the demonstration application of new energy vehicles in my country began, which was called the "first year of new energy vehicles in China";

Since 2009, new energy vehicles have entered the industrialization stage. The country has introduced a series of policy support, including vehicle purchase subsidies and purchase tax exemptions, and my country's new energy vehicles have entered a rapid development track.

From 2010 to 2015, China made important breakthroughs in battery technology, motor technology, and electronic control technology, laying a solid foundation for the popularization of new energy vehicles in China.

On March 31, 2016, Tesla announced the release of Model 3;

On July 10, 2018, Tesla entered the business world and truly took off.

If Hao Qiang was interested in entering the new energy vehicle field, the best time would be around 2008.

At that time, new energy vehicles were in the initial stage of demonstration application and had huge market potential.

He needs to establish a solid foundation before 2015 so that he can gain an advantageous position before international giants such as Tesla enter the domestic market, or even prevent them from entering the domestic market.

If Tesla is allowed to enter China smoothly for development as it did in the previous life, the country will have a strong competitor, which will undoubtedly intensify market competition.

At the same time, this also provides Musk with a lot of financial support for developing the Starlink project, which is something Hao Qiang does not want to see.

No one wants to have so many low-Earth satellites overhead, but there is nothing we can do about it.

Hao Qiang didn't like them either and once fantasized about using a hammer to knock them down one by one.

Of course, Musk is an entrepreneur that Hao Qiang admires very much.

However, they are from different camps and have conflicting interests, so they can only meet on the battlefield.

If Tesla's development can be stopped, most of Musk's funding sources can be cut off, making his rocket dream out of reach.

It can be said that Musk is one of Hao Qiang's most powerful potential opponents in the future.

Hao Qiang has plug-ins, but Musk has the support of the entire United States.

Thinking of this, he did not feel afraid, but instead it aroused Hao Qiang's excitement to confront a powerful opponent.

It’s just like playing Honor of Kings. The opponent is too weak and it feels really boring to win by bullying them.

After more than ten minutes, Hao Qiang completed the fusion technology.

He is full of confidence in manufacturing electric motorcycles and looks forward to creating an excellent product.

Looking back at the electric motorcycle he had assembled in the past few days, he found many shortcomings and it was as unsightly as a pile of dog shit.

Next, Hao Qiang will start leasing a factory and setting up a new company, taking solid steps towards realizing his electric motorcycle dream.
