Start with a blacksmith shop

In terms of the appearance of the car, I chose a model that was designed in advance. Just from the appearance, I can tell that this car is a hard-core SUV.

The target audience is young tough guys. Of course, it is not possible for all tough guys to drive. Nowadays, some petite and exquisite little girls also like to drive big cars.

Since it is positioned as an SUV, 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 placed in front of him, the rest of the matter will be easier to talk about, and the structure of the car will be determined.

Using a configuration of one motor in the front and two in the rear, the front motor is responsible for the rotation of two wheels on one axle, while one motor on the rear axle is responsible for one wheel.

After the car layout is decided, there is another important direction that needs to be determined later, and that 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.

Both types of 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 by the stator winding and the magnetic field induced by the current in the rotor winding interact physically with each other to generate electromagnetic torque drive to drive the rotor to rotate.

To put it simply, we can think of it as the simplest Audi double-diamond motor, with only a stator and a rotor. Of course, the Audi double-diamond 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 a simple structure, high reliability and easy cost control. It also has good high-speed performance and can accelerate to 100 kilometers faster.

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

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

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

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

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

As for its shortcomings of low efficiency, is it still a problem after having wires containing graphene materials? Super large capacity battery, just splurge.

Need an efficient and sophisticated cooling system? It’s still graphene, but in the end it doesn’t have an advantage in terms of volume and weight. He chose to build a large SUV. Is the volume and weight still a problem?

With the research direction, everything is easy to say. Isn't it just a hack to upgrade this kind of motor?

As long as the shortcomings of this induction motor are made up and upgraded, this motor will undoubtedly be the most suitable for the electric car he is about to build.

Then he started researching this kind of asynchronous AC motor. The first thing was the bearing, and he still used a unique air bearing.

Afterwards, for the production of the stator and rotor, the winding enameled wire chosen was his specially made graphene copper wire.

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

As he researched, this induction motor was upgraded. Of course it was also produced by him.

There are two kinds of motors in total, one for the front axle and one for the rear axle. The front axle motor is relatively more powerful than the single one used for the rear axle, but the total power is not as high as the two motors for the rear axle combined. big.

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

When he took out the three-day motor, he was shocked. Why?

It may not be intuitive to say kilowatts. When converted into horsepower, 1,280 watts is more than 1,522 horses. Do you know how much horsepower Kyushu's current 99 main battle has? Around 1,500 horsepower.

That is the power that can move a tank weighing more than fifty tons, but now he can achieve it with only three electric motors.

Let’s not talk about the hardships involved. Anyway, electric motors have once again derived many new materials.

At this time, he was also thinking that he should choose a dual-motor configuration for this car. The three-motor layout he originally thought of was indeed hasty.

In fact, this kind of configuration can be used in his dream car, and it seems that the distance between him and Aslada has become one step closer.

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

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

At this moment, the total power of this car has been truly determined, 800 kilowatts, and the final horsepower is 1,087 horses, which is also an extremely abnormal figure.

With all these things in place, it’s time to design the battery pack.

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

In other words, the car he came out with can drive 3,500 kilometers from the Peking runway as long as it is fully charged.

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

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

It was also during this period that he was not just sitting and researching in the virtual laboratory. In reality, he also dismantled the electric cars he bought back to pieces one by one.

No car was left safe from the murderous hands. Of course, the one who had the most objectionable opinion was none other than Liu Xiaodong, who went to buy a car with him.

This fat man looked at so many new cars and went on Huangquan Road before even having fun on the road. Who wouldn't feel sad when he saw this?

It was also under his strong suggestion that Li Zhenhua added another task during the day, which was to assemble all these cars.

After these cars were reinstalled, Liu Xiaodong used them as company vehicles and distributed them as benefits to the company's middle and senior managers.

This is also the first time that a car has been allocated to middle and high-level people. Previously, each person was allocated a top-spec White Tiger 7.

Of course, the suture monster Gaohe that Li Zhenhua used was still placed in his workshop.

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

What's left is the car's interior, as well as adding various human-machine systems.

So next he plans to get an electric motor and supporting batteries and other things in reality first.

First, he used his old Poussin as an experiment and modified it from a fuel vehicle to an electric vehicle.

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

Just think about it, who would bother to convert an old Poussin from the last century into an electric car?

But this kind of magical thing happened to him, which was completely a sign of powerlessness.

Starting from the manual preparation of graphene, we started working on batteries, motors and other components one by one.

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

The next step was to start with his Poussin. At this time, he got into the virtual laboratory again and dismantled his second-hand old Poussin.

Looking at the rusty and rotten chassis of Poussin that appeared in the laboratory, he was speechless.

This situation was something he didn't expect. He originally wanted to modify the car, but this situation occurred in the virtual laboratory. Fortunately, he had not touched the old car in reality.

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

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

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

Calculating conservatively based on 6 tons, he can completely transform such a Poussin into a bulletproof vehicle.

What started out as a temporary idea to experiment with batteries and motors led him to make it bigger and bigger.

Then, all the new materials that had been produced before were revealed in front of his eyes, and the one with the lightest weight and the strongest strength was selected from them to use as the car shell.

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

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

In addition, non-Newtonian fluid theory was used to create a liquid bulletproof material using special materials in the middle of each layer, filling the only gaps in the layers.

The average thickness of the entire car shell reached three centimeters, and the thickest door reached a terrifying fifteen centimeters.

In this way, he replaced everything inside the car. Even the tires and wheels were specially made. The curb weight of the entire car reached 5 tons.

Of course, all the power systems inside have been replaced with batteries, motors and other things he made, and the battery pack sacrificed part of the trunk space.

And lathe glass can no longer be called glass at this 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.

He finally got the whole car out. It didn't look any different from the outside, but it changed a lot on the inside.

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

The original total weight of the car was only 1.1 tons, but now it has reached a total weight of 5 tons. However, due to the thickness of the car shell, the total space inside the car has taken up three millimeters.

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