I chose the appearance of the car. A model designed in advance was previously known to be a hard-core SUV from the appearance alone.

The people are young and tough guys, of course, they are not sure that they are all tough guys to drive. Nowadays, some petite and delicate little girls also like to drive big cars.

Since 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 a city SUV.

All the conditions are placed in front of him, so the subsequent things will be easy to talk about, so that the structure of the car will be determined.

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

The car layout determines, so there is another important direction to be determined at the back, that is, the type of electric 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, commonly used AC asynchronous motors in electric vehicles.

It is a type of motor that causes the rotational magnetic field formed after the stator winding and the magnetic field that induced current in the rotor winding to physically interact with each other and generates electromagnetic torque drive, and drives the rotor rotation.

Simply put, we can regard it as the simplest structure of Audi double-drill motor, with only the stator and rotor. Of course, Audi double-drill motor is the simplest DC motor.

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

Among them, the induction motor has a simple structure, high reliability and high cost control, and has better maintaining high-speed performance and can achieve faster acceleration of 100 kilometers.

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

These two motors are just the 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, the cost of permanent magnet motors is high, and it is easy to cause permanent magnet demagnetization in environments with large temperature changes, and poor reliability in complex environments such as high-position vibration. These are also indisputable facts.

After understanding the advantages and disadvantages of the two motors, Li Zhenhua still chose this induction motor that is relatively reliable, accelerates rapidly over 100 kilometers, and has good high-speed performance.

As for its shortcomings and low efficiency, is it still a problem after having wires with graphene material added? Just squander the battery with super large capacity.

Need an efficient and complex cooling system? It is still graphene, and in the end he does not have the advantage in volume and weight. He chose to make large SUVs. Is this a problem?

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

As long as all the shortcomings of this induction motor are made up, after upgrading, this motor is undoubtedly the most suitable one for the electric car he is about to get out.

Then he conducted research on this asynchronous AC motor. First of all, it was the bearing, and still chose a unique air bearing.

Afterwards, the stator and rotor were made, and the selected winding enameled wire was specially made by him, graphene copper wire.

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

With his research, he upgraded this induction motor and of course he also made it out.

There are two motors in total, one for the front axle and one for the rear axle. The motors of the front axle are relatively larger than those used for the rear axle, but the total power is not as large as the two motors of the rear axle.

The power of the front axle is 480kw, while the power of the single motor 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 electric motor out of these three days, he was shocked. Why?

It may not be intuitive to say that kilowatts are not very intuitive. If you convert 1280 trunks into horsepower, it is more than 1522 horsepower. I know how much horsepower is in Kyushu's current main battle? It is about 1500 horsepower.

That is the power that can drive more than 50 tons of tank weight, and now he has achieved it with just three electric motors.

I won’t talk about the hardships in the middle, anyway, there are motors that have once again produced many new materials.

At this time, he was also thinking that this car should choose a dual-motor configuration. The three-motor layout I thought about at the beginning was indeed hasty.

In fact, this configuration can be used on his dream model, and it seems that the distance between him and Asrada is one step closer.

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

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

At this moment, the total power of this car was truly confirmed. The final horsepower was 800 kilometres, and the final horsepower was 1,087 horses, which is also an extremely abnormal data.

With all these things in hand, it’s time to design a battery pack.

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

In other words, this car he came out. As long as he can drive 3,500 kilometers, he can run from the Beiping runway west.

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

No matter how perverted the data was, it became common in his eyes.

It was also during this period that he did not just sit in a virtual laboratory to study. In reality, the electric cars he bought were also broken one by one.

No car left can avoid being harmed. Of course, the most objection among them is not someone else. It is Liu Xiaodong who followed him to buy a car.

This fat man looked at so many new cars and had just started playing in the road before he even had fun. Who wouldn’t feel sorry for whom he met?

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

After these cars were reinstalled, Liu Xiaodong distributed cars as a company and distributed them to the company's middle and senior management as a benefit.

This is also the first time that middle and high-rise buildings are equipped with cars. Before, each person has been given a top-end White Tiger 7.

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

And his work in the virtual laboratory has completed most of it.

What is left is the interior of the car, as well as the addition of various human-machine systems and other things.

So he plans to get a motor and a matching battery in reality.

First, he used his old Poussan as an experimental product and changed it from a fuel vehicle to an electric vehicle.

This is not too difficult for him, but to be honest, his illness is also very ill.

Just think about it, who would have worked hard to convert an old Poussan from the last century into an electric car?

But this kind of magical thing happened to him, which was a sign of strength and no place to use.

Start by hand-preparing graphene, and start with the use of batteries, motors and other components one by one.

Two months later, he finally used existing equipment in the laboratory to get all the parts used in the electric vehicle.

The next step was to start his Poussan, and at this time he got into the virtual laboratory again and dismantled his second-hand Poussan.

Looking at the rusty and alkaline-decaying chassis in the laboratory, he was speechless when he looked at it.

This was something he had never expected. He wanted to renovate the car, but this happened in the virtual laboratory. Fortunately, he had never moved this old car in reality.

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

The original Poussan has a displacement of 95 horsepower of 1.8 and can carry a weight of 1.1 tons.

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

The conservative point is calculated based on 6 tons, and he can completely transform such a POSIN according to the standards of bulletproof cars.

It was originally just a temporary idea to experiment with batteries and motors, making him bigger and bigger.

Then, all the new materials that were made before were found, and one of the lightest and most powerful ones was picked out from it. As the car shell,

Under his wild idea, the car's shell is 0.75mm titanium alloy material, and inside it is a newly developed graphene composite bulletproof insert, each piece is 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.

In addition, non-Newtonian fluid theory is used in the middle of these layers to make a liquid bulletproof material using special materials, filling the gaps seen in each layer.

The entire shell was pulled down by him and the average thickness reached three centimeters, and the heaviest and thickest door reached a terrible fifteen centimeters.

In this way, he changed the inside of the car, even the tires and wheels were specially made, and the curb weight of the whole vehicle reached 5 tons.

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

And lathe glass can't be called glass at this moment, because it's 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 out the whole car. He saw that the appearance had not changed at all, but the inside had changed drastically.

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

The car, which originally weighed only 1.1 tons, now has a total weight of 5 tons. The space inside the car consumes three millimeters in total due to the thickness of the car shell.
