Industrial motors cannot be used in electric vehicles.

Electric vehicles have to be blown by wind and rain, exposed to the sun and rain, and subjected to continuous vibration, as well as frequent shutdown and starting. If there are no special modifications, it will be over in two months at most.

There are many industries and materials involved in modifying motors.

The first is the coil.

Copper coils are the only option.

However, there are many models in the copper coil.

High-end copper coils still rely on imports.

This is another weakness.

The best quality ultra-fine transmission copper alloy cable, originated from the French company Axon. The supply is very small and extremely expensive.

Fortunately, Wang Bu'an has the No. 8 machine.

Machine 8 is capable of producing a wide range of copper wires with excellent performance.

With high-quality copper wire, the next question is the stator and rotor. This requires the use of a special alloy:

High magnetic inductance oriented silicon steel.

The product has the characteristics of high magnetic induction strength and low iron loss, and can achieve significant energy saving and emission reduction effects in the application of the power industry, China is the world's largest importer of oriented silicon steel, accounting for more than 10% of the world's total annual import.

Well, that's another huge weakness.

The high-end products are mainly from Toei Nippon Steel NSC and Kawasaki Steel. There are also AKs of the US imperialists, Posco of South Korea, and thyssenkrupp of Germany.

These companies, all of them are giants. They have a complete monopoly on the international high-end market.

The market capacity is hundreds of billions of dollars.

Only Baosteel and Shougang Qiangang can produce part of it in China.

"That's it!"

"That's it!"

Niu Erlang couldn't bear it at first.

If you don't have the best, then use the ordinary one.

It was not easy to find the right stator and rotor, plus the copper coil, which can be assembled and used.

The rest of the materials are barely enough.

Otherwise, I'm afraid the final cost will be very amazing. It can't be sold at all.

Finally, three days later, the first prototype was released.

Niu Erlang drove the sample car, turning around the factory, accelerating, slowing down, braking sharply, turning, and reversing......

The speed of the prototype was limited to 40 kilometers per hour.

This is what Wang Bu'an strongly demands.

This is an electric car, not a motorcycle.

Almost no one who drives an electric car has a driver's license.

In other words, none of these people have received professional driving training, and once the speed is too fast, they are prone to accidents.

Originally, according to Wang Buan's requirements, the speed should be limited to less than 25 kilometers per hour. Because that's what the national standard is. But Niu Qinghai and Niu Erlang strongly objected. Their arguments are also very strong. At present, none of the electric vehicles comply with this standard. Otherwise, it is a fool, and there is definitely no market.

Besides, 25 kilometers per hour is simply a waste of such an advanced technology as hydrogen storage alloys. With the strong power of the hydrogen storage alloy, there is no problem in running 125 kilometers per hour.

In the end, after heated discussions, the two sides forcibly limited the speed to 40 km/h. In case of speeding, cut off the power immediately.

Wang Bu'an didn't want to become a murderer as soon as the hydrogen storage alloy came out.

There is no problem with normal driving.

Next up is the ability to climb hills.

It's easy to experiment. Niu Qinghai, Niu Erlang, father and son went together.

The two of them combined, at least four hundred catties. plus the 100 catties of the electric car itself, a total of 500 catties.

They need to conquer a slope of thirty degrees.

It's the slope.

Not angles.

Every 100 meters of elevation of 30 meters is a slope of 30 meters.

The electric car went uphill smoothly.

The power is incredible.

Niu Erlang then proposed to try a slope of forty-five. It's a very steep slope too.

Not to mention electric cars, even motorcycles are struggling.

However, electric vehicles are still a strong and successful climb. It's just that the front of the car wants to be cocked a little.

This is caused by the overall structure of the electric vehicle. The front is light and the back is heavy.

Of course, a slope of 45 degrees is not found in ordinary places.

The average road, with a slope of thirty, is already the limit. If you exceed 30, you will need to design an S-bend.

During the test, something went wrong.

The chain broke.

The strength of the conveyor chain cannot support such a strong power.

An electric car is not the same as a gasoline engine.

At the time of start-up, the torque of the electric car is very high.

In daily life, you can actually see that the starting speed of electric vehicles is extremely fast, and the acceleration is also very fast.

Normally, the average gasoline engine vehicle cannot keep up with the starting speed of the electric vehicle.

However, if the torque is too high, the consequence is that the chain breaks.

Ordinary electric cars with a voltage of up to 80 volts.

However, the output of the hydrogen storage alloy is 380 volts.

This is the design that Niu Jiro insists on. He just likes the feeling of flying.

He just likes to drive an electric car, and when he starts at the green light, he can leave all the other cars far behind. I guess there are many people who like it too.

To intensify the start-up speed, he insisted on outputting 380 volts. Thus, the chain and gear are tragic.

The terrifying torque can easily tear the chain and even the gear to break.

Is there anything that can be corrected?

Use high-quality chains and gears.

This requires the use of high-quality hard alloys, or high-temperature corrosion-resistant alloys.

Well, the problem is that such a chain, such a gear, is not produced in our country. Domestic specifications cannot meet such high requirements. Must be dependent on imports.

In fact, in China's automobile industry, the chains or steel belts used in CVT continuously variable transmissions are basically imported.

In Wang Buan's hands, there are high-quality cemented carbide. But there are no processing companies!

He also couldn't turn carbide into chains or steel belts.

This needs to be matched by downstream enterprises.

A small electric car involves so many industries and so many raw materials, which Wang Buan couldn't imagine before.

It was such a small electric car that made him discover so many manufacturing shortcomings.

Rubber, Chemical, Metal, Ceramics...... There is still a long way to go!

By the way, I forgot one.

Glass.

Including glass-ceramic, float glass, specialty glass, ultra-thin flat glass, laminated glass, etc.

Finally, there are LED phosphors.

It's just that a car lamp, and it involves a huge gap.

Good quality lights can be used for more than five years. If it's of poor quality, it's probably over in two or three months.

Among them, the most critical material is LED phosphor.

Well, that's another weakness.

Wang Buan felt that he couldn't remember so much.

How do you feel so much weakness?

Fortunately, it finally came out in the end.

It took a week to finally get the prototype out.

After the test, the quality is still relatively reliable.

Of course, it also comes at a high cost.

Originally, hydrogen storage alloy could save a lot of costs, but it was raised by the cost of other parts.

The final raw material cost of each car is more than 2,000 yuan.

This is already very expensive for a two-wheeled electric bike.

If you are calculating depreciation, labor, taxes, advertising, factory rent, etc., the cost is even higher.

Midnight Cowherd wanted to back down several times.

His budget is grossly inadequate.

Who knew there would be so many things that needed to be changed.

For a hydrogen storage alloy unit, it feels like the entire electric car has been redesigned.

Fortunately, there is Wang Buan's strong support.

Wang Buan is not short of money.

What he lacks is the opportunity to show.

He needed to take this opportunity to officially launch the hydrogen storage alloy on the market.

Moreover, through the transformation and assembly of electric vehicles, he is also deeply aware of the shortcomings of China's manufacturing industry. In the future, when you come into contact with the shock wave, you can choose the industry or machine in a targeted manner. As long as there is an industry that can rob the foreign market, he wants it all.

"Success. ”

"Very successful. ”

Niu Qinghai was very satisfied with the preliminary test results. Next, we are ready to invite dealer representatives to come over and experiment together.

Wang Buan reminded that you can call a few media reporters. If you can't afford the print media, you can ask the online platform. Anyway, it is necessary to increase the exposure as much as possible, so that everyone knows that there is now a new energy source called hydrogen storage alloy. As long as you keep this selling point in mind, you can rubbish everything else.

Frankly speaking, except for hydrogen storage alloy, Zunchi electric vehicles have no characteristics.

Niu Qinghai is still counting on selling at a sky-high price of 4999 yuan!

Wang Buan felt that he was dreaming.

Of course, he won't pour cold water on it for the time being.

Maybe I miscalculated?

"Live broadcast?Internet celebrity?" Niu Erlang suddenly became energetic, "I'll ask a few Internet celebrity girls to come over." ”

"Do it yourself. "Wang Buan doesn't care.

It doesn't matter what method you use.

As long as you can make it popular, it's a good way.

Internet celebrities too.

Live broadcast.

He felt exhausted.

This week, he ate and lived in the factory, which was really unprecedented.

However, there is no way, the relevant technical information, except for him, no one else understands at all. If he wasn't there, there was no way to deal with it.

Now it's finally over. He was going back to the presidential suite at the Dynasty Hotel and had a good rest.

He had already secured the presidential suite at the Dynasty Hotel. 30,000 yuan per night.

However, the ideal is beautiful and realistic skinny.

He can't go yet.
