Starting Off With A Blacksmith Workshop

In terms of the appearance of the car, I chose a model that was designed in advance. Just from the appearance, I know that this car is a **** SUV.

The target audience is young tough guys, of course, it doesn't mean that all tough guys drive. Now some petite girls also like to drive big cars.

Now that the SUV is positioned, the option of four-wheel drive must be added, but the attributes of electric vehicles determine that this SUV is only suitable as an urban SUV.

With all the conditions in front of him, it will be easy to talk about the following things, so that the structure of the car will be determined.

The motor configuration of the front one and the rear two is adopted. The front motor is responsible for the rotation of two wheels of one axle, and one motor of the rear axle is responsible for one wheel.

After the car layout is determined, there is another important direction to be determined, which is the type of motor suitable for electric vehicles.

There are two types of motors, one is an induction motor and the other is a permanent magnet motor.

These two motors have their own advantages and disadvantages. Let’s talk about induction motors first. AC asynchronous motors are commonly used in electric vehicles.

It is a type of motor in which the rotating magnetic field formed after the stator winding and the magnetic field of the induced current in the rotor winding physically interact with each other to generate electromagnetic torque drive and drive the rotor to rotate.

To put it simply, we can regard it as the simplest Audi double drill motor with only a stator and a rotor. Of course, the Audi double drill motor is the simplest DC motor.

As for the permanent magnet motor, it is actually very simple. It is to add permanent magnets to the stator to further improve the performance of the motor. This is the main difference between the two motors.

Among them, the induction motor has the advantages of simple structure, high reliability, easy cost control, good high-speed performance, and faster acceleration from 100 kilometers.

The permanent magnet motor has the advantages of small size, light weight, good cruising range, good speed regulation performance, high torque density, power density and efficiency.

These two motors are just opposite in some things. For example, induction motors are not as good as permanent magnet motors in terms of volume and weight.

Induction motors require efficient cooling systems, but permanent magnet motors do not,

However, it is an indisputable fact that the cost of permanent magnet motors is high, it is easy to cause permanent magnet demagnetization in an environment with large temperature changes, and the reliability is poor in complex environments such as high vibration.

After understanding the advantages and disadvantages of the two motors, Li Zhenhua still chose this relatively reliable induction motor with fast acceleration from 100 kilometers and good high-speed performance.

As for his shortcoming of low efficiency, is it still a problem after having a wire with graphene material added? With a super-capacity battery, just splurge.

Need an efficient and sophisticated cooling system? It is still graphene, but in the end it does not have an advantage in terms of volume and weight. He has chosen to make a large SUV. Is the volume and weight still a problem?

With the research direction, everything is easy to talk about, isn't it just to upgrade this kind of motor?

As long as the shortcomings of the induction motor are made up for, after the upgrade, this motor is undoubtedly the most suitable for the electric car he is about to produce.

Then he started research on this kind of asynchronous AC motor, first of all, the bearing, still using the unique air bearing,

After the production of the stator and rotor, the selected winding enameled wire is his special graphene copper wire.

It seems that graphene has become a universal additive since he prepared it. Graphene must be added everywhere in this car.

Following his research, this induction motor was upgraded by him. Of course it was made by him.

There are two types of motors in total, one for the front axle and one for the rear axle. Compared with the two motors on the front axle, the power of the motor on the front axle is higher than that of the single one used on the rear axle, but the total power is not the sum of the two motors on the rear axle. big.

The power of the front axle is 480kw, while the single motor power of the rear axle reaches 320kw, while the total power of the rear axle is 640kw, and the total power of the three motors reaches an astonishing 1120kw.

When he got the three-day motor out, he was stunned, why?

It may not be intuitive to say kilowatts. If 1280 kW is converted into horsepower, it is more than 1522 horsepower. Do you know how much horsepower is the current 99 main battle in Kyushu? Around 1500 horsepower.

That was enough power to drive a tank weighing more than 50 tons, but now he achieved it with only three electric motors.

Not to mention the hardships in the middle, anyway, there are many new materials derived from electric motors again.

At this time, he was also thinking, let's choose a dual-motor configuration for this car. The three-motor layout that he thought of at the beginning was indeed sloppy.

In fact, such a configuration can be used on his dream car, and it seems that the distance between him and Aslada has been brought closer.

The layout was changed again, and the car changed from the original three-motor layout to the front and rear dual-motor layout again.

The power of the front axle was replaced by a 480kw motor, while the rear axle was replaced by a 320kw motor.

At this moment, the total power of this car can be regarded as truly determined. At 800 kw, the final horsepower is also 1087 horsepower, which is also an extremely abnormal figure.

When all these things are available, it is time to design the battery pack.

Finally, in order to allow the car to reach a mileage of 3,500 kilometers under extreme conditions, combined with the designed electric motor, the battery pack was finally designed to hold a capacity of 800kwh.

In other words, the car he came out of, as long as it is fully charged and can travel 3,500 kilometers, it can go west from the Beiping runway.

After all these major systems were designed, his heart was completely numb the moment the graphene battery was obtained.

No matter how abnormal the data is, it becomes commonplace in his eyes.

It was also during these days that he didn't just sit and study in the virtual laboratory. He also dismantled all the electric cars he bought in reality.

There is not a single car left that can be spared from the poisonous hands. Of course, the most critical opinion among them is none other than Liu Xiaodong, who went to buy a car with him.

This fat man looked at so many new cars, and he went to Huangquan Road before he was on the road to have fun. Whoever saw him would not feel distressed?

Also under his strong suggestion, Li Zhenhua added another daytime job, which was to assemble all these cars.

After these cars were reinstalled, Liu Xiaodong distributed them as company cars, and distributed them as benefits to the company's middle and high-level managers.

This is also the first time that a car is allocated to the middle and high-level. Before, each person was allocated a top-equipped White Tiger 7.

Of course, the stitching monster Gao He used by Li Zhenhua is still in his workshop.

And most of his work in the virtual laboratory has been completed so far.

What remains is the interior of the car and the addition of various man-machine systems.

So he plans to get a motor and supporting batteries in reality first,

First use his old Poussin as an experimental product, and change it from a fuel car to an electric car.

This is not too difficult for him, but speaking of it, his illness is not serious.

As long as you think about it, who would take the trouble to change an old Poussin from the last century into an electric car?

But this kind of magical thing happened to him, it was completely a manifestation of powerlessness.

Starting from the manual preparation of graphene, one by one for batteries, motors and other components.

After another two months, in the laboratory, he finally used the existing equipment to get all the parts used in the electric car out.

The next step was to attack his Poussin, and it was also at this time that he got into the virtual laboratory again and dismantled his second-hand old Poussin.

Looking at Poussin's rusted and rotten chassis in the laboratory, he was speechless.

This situation was beyond his expectation. He wanted to remodel the car, but this happened in the virtual laboratory. Fortunately, he never touched the old car in reality.

Looking at the car shell and chassis that could no longer be used, a more magical idea came to his mind.

The original Poussin, with a displacement of 1.8 and a horsepower of 95 horsepower, can carry a weight of 1.1 tons.

And his current motor can provide 652 horsepower, which is 6.8 times that of the original, that is to say, he can transform the car into a maximum of 7.48 tons.

Conservatively calculate it based on 6 tons. He can completely transform such a Poussin according to the standard of a bulletproof vehicle.

It was just a temporary idea to experiment with batteries and motors, and he made it bigger and bigger.

Then all the new materials that were obtained before were presented in front of my eyes, and the lightest and strongest one was selected from it as the car shell.

Under his unconstrained ideas, the outer shell of the car is made of 0.75mm titanium alloy material, and the inside is a newly developed graphene composite bulletproof plate, each one centimeter thick,

The inner layer is composed of carbon fiber and aramid fiber. Layer after layer of bulletproof material gradually becomes the composite shell of the car.

And in the middle of these layers, non-Newtonian fluid theory is used to make a liquid bulletproof material with special materials, which fills the gaps in each layer.

The entire car shell was removed by him, with an average thickness of three centimeters, and the thickest part of the door reached a terrifying fifteen centimeters~www.wuxiaspot.com~ In this way, he changed the entire car inside and out, even the tires and wheels are specially made, and the curb weight of the whole vehicle has reached 5 tons.

Of course, the power system inside has been replaced with the battery motor and other things he made, and the battery pack sacrificed part of the trunk space.

And lathe glass cannot be called glass at the moment, because it is not glass at all.

It is a transparent aluminum-magnesium alloy, which is much more reliable than bulletproof glass, and the thickness of this transparent metal reaches five centimeters.

The whole car was finally taken out by him. It looked unchanged from the outside, but the inside was greatly changed.

No one would have thought that such an old model from the 1980s would have a bulletproof electric car inside.

The car originally weighed only 1.1 tons, but now it has a total weight of 5 tons, and the relative space inside the car is 3 millimeters in total due to the thickness of the car shell.

Looking at the no longer ordinary Poussin in the virtual laboratory, he kicked towards the car door fiercely.
