Su Han said: "I just want the style of a sports car. I want a car that is younger, sportier and more technological. Our new energy vehicles are the latest type of automobiles, and they will lead the trend and the changes of the times in the future. Such an awesome car does not have a bright and blind appearance, and it is embarrassing to say that it is a new energy vehicle. Look at the cars you've designed! It's unappetizing to look at it, and you still want users to pay? Isn't there something wrong with the brain of whoever buys such an ugly car? ”

Nie Anbang didn't know what to say.

Originally, he thought that Su Han would be very satisfied with the models he designed, but he didn't expect to be degraded by the other party for nothing.

But the problem is that this model is the most cost-effective one.

Processing costs are also minimal.

If it's all by the standards of a sports car, how much does it cost?

Nie Anbang said: "Mr. Su." If we all design according to the standards of sports cars. I'm afraid the cost is not low! ”

Su Han said: "What cost? We are a new energy vehicle, there is neither an engine, nor a gearbox, not even a transmission and a fuel tank. At most, the battery pack and power plant. The outer shell is also stamped and molded in one piece. You tell me what the cost can be? I don't think your mind has jumped out of the box of the original car design.

You look at the cars that you designed, and the front grille also has it. We are electric cars and we don't have engines. What do you want the grille for? Why can't you just close it up and look a little cleaner.

Wouldn't the pneumatic shape be better in this way?

I just want this look that is very smooth and clean.

The interior is the same, don't have the cumbersome interior of a traditional car, and the interior should be clean and tidy. When the time comes, the integrated integral stamping will not only make the body stronger, but also save money. After speaking, Su Han took out a disc and said, "This is a model I designed." Take a look! That's what I wanted. Don't get those outdated classic cars to come to the lake and mess with me. ”

Nie Anbang hurriedly put the disc into the CD drive and exported the file.

The surrounding designers also came over.

It seems that they all want to see how awesome the car designed by the boss himself is.

When the file is loaded successfully.

Everyone was stunned.

The shape of this car is too awesome!

The sleek shape is like a car that can only exist in a science fiction movie.

Since Su Han used Longhan CAD software to design the car, it is natural to see a lot of details.

It was only when these self-proclaimed professional designers zoomed in on the details that they found out.

Su Han's design details are many and varied, and they are very amazing.

Covers almost every step of the car's shape.

As some professional car design people, knowing so many details represents a lot of work.

Such an awesome car was actually designed by the boss himself.

It's incredible.

Nie Anbang said: "Mr. Su, the car you designed is too beautiful. Have you studied automotive design before? ”

Su Han said: "I've just read a few design textbooks. ”

Nie Anbang couldn't say anything when he heard this.

After reading a few textbooks, you can design such a beautiful car.

No wonder he is a double doctor from Mushui University.

The national prefix key project has won many awards!

The legendary super genius turned out to be so awesome.

Su Han said: "Although you are a professional car designer, your past experience and ideas are bound by too many rules and regulations, and the products you design have no soul and a sense of the future at all. If you can only design what is in this world. And how to lead this era forward?

Our company is an epoch-making company. Our products are also epoch-making products. And you are the designers who are about to change this era. We must let everyone know that the strength of the Chinese people is not only in production capacity, but also in terms of design ability. In any case, you have to design the best car in the world, so that all the people in the world can drive our car, and everyone will praise our car. ”

Everyone suddenly became excited when they heard this.

It seems that designing the best car in the world is the dream of all professional designers.

If you can design a good car that sells well all over the world.

Then it is definitely the honor of a professional designer's life.

Su Han left a new task for the Design Power Department.

The design of three completely new models had to be completed.

When the time comes, check it yourself.

……

The group then moved on to the power plant department.

The power plant department is the department with the largest number of people in the entire R&D center.

Because the interior of an electric vehicle is mainly divided into two major components.

Battery packs and power units.

The power plant of electric vehicles is still a completely new field for automotive designers today.

Since it had never been seen before, there was no template to draw from, so everything had to be started from scratch.

Nie Anbang asked people to call up the powertrain design drawings at this stage, and then showed Su Han one by one.

Although in Su Han's opinion, the powertrain they designed was very simple.

But I can see a lot of new and strange ideas, and it seems that the other party is still very attentive, but it just needs enough time to precipitate.

Nie Anbang said: "The biggest problem with the power plant now is the style of the motor. The energy consumption of mainstream induction motors is relatively large, and excessive consumption will seriously affect the cruising range. And the starting torque of the induction motor is not strong enough. When the speed is high, the torque will decrease sharply at the same time, and there is not so much power.

As for the design of the permanent magnet synchronous DC motor you mentioned, after laboratory testing, it was found that the heat generation was too large, and the heat was large, and the magnet would be demagnetized. To solve the problem of demagnetization, the problem of heat dissipation must be solved. But there's no good way to do it yet. ”

Su Han nodded and said, "I've also thought about what you said. In fact, the main heat source of the motor comes from electromagnetic induction. I gave you a concept that you can think differently, such as making a slot in the core and putting a permanent magnet in the slot. In this way, the interaction between the magnetic field of the permanent magnet and the electronic coil can be reduced, and the heat source can be greatly reduced.

Of course, this also raises a new problem. That is, the permanent magnet is wrapped in the iron core, and at high speed, it will cut the magnetic inductance line, generating a back electromotive force to cancel out the driving voltage of the stator input.

If you want to solve this problem, you can't solve it with hardware design.

I think it is possible to design a micro-controlled circuit board and a set of algorithms to solve the problem of driving voltage and back EMF. ”

Nie Anbang was stunned! "Algorithm! But the algorithm is used on a computer! We don't have any experience with that. ”
