In the shape of the car, I chose a model that was designed in advance, and I know that this car is a hard-core SUV just from the appearance.

The positioning crowd is a young tough guy, of course, this may not be all tough guys to drive, and now there are some petite and delicate little girls who 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.

All the conditions are in front of him, then the rest of the things are easy to say, so that the structure of the car is determined,

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.

The layout of the car is decided, so there is an important direction that needs to be determined, that is, the type of electric motor suitable for electric vehicles.

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

These two types of motors have their own advantages and disadvantages, first of all, induction motors, AC asynchronous motors commonly used in electric vehicles,

It is a type of motor that is driven by the rotating magnetic field formed after the stator winding and the magnetic field that induces the current in the rotor winding to produce electromagnetic torque drive and drive the rotor to rotate.

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

As for the permanent magnet motor, in fact, it is very simple, that is, to add a permanent magnet to the stator to further improve the performance of the motor, which is the main difference between the two types of motors.

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

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

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

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

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

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

As for his disadvantages, low efficiency, is it still a problem after having wires with graphene material incorporated? The super-large capacity battery can be splurged.

Need an efficient and sophisticated cooling system? is still graphene, and in the end, it does not have an advantage in volume and weight, he chooses to make a large SUV, this volume and weight is still a problem?

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

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

Then he carried out 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 winding enameled wire selected 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 in this car.

With his research, this induction motor was upgraded by him. Of course, he also made it.

There are two kinds of motors, one for the front axle and one for the rear axle, and the motor on the front axle is relatively larger than the single motor used on the rear axle, but the total power is not as large as the two motors on the rear axle combined.

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

When he got the motor out for three days, he was stunned, why?

It may not be intuitive to say that kilowatts, 1280 watts are converted into horsepower, which is more than 1522 horses, do you know how much horsepower is the current 99 main battle in Kyushu? About 1500 hp.

That's the power to drive the weight of a tank of more than fifty tons, and now he can achieve it with just three electric motors.

Not to mention the hardships in the middle, anyway, there are electric motors that once again derive many new materials.

And at this time, he was also thinking, this car still chooses a dual-motor configuration, and the three-motor layout 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 Aslarda has been shortened by one step.

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 on the front axle has been replaced by a 480 kW motor, while the rear axle has been replaced by a 320 kW motor.

At this moment, the total power of this car can be regarded as really determined, 800 kilometres, and the final horsepower is also 1087 horsepower, which is also a very perverted data.

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

In the end, in order to allow the car to reach a range of 3,500 kilometers in extreme conditions, combined with the designed electric motor, the battery pack was finally designed to hold a capacity of 800 kWh.

That is to say, he came out of this car, as long as it can travel 3,500 kilometers at the full point, it can be stiffened from the west of the Beiping runway.

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

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

It was also during this period that he didn't just sit in the virtual lab and research, but also let him dismantle the electric cars he bought back in reality.

There is no car left that can avoid being poisoned, of course, the most objectionable person in the middle is none other than Liu Xiaodong, who followed him to buy a car.

This fat man looked at so many new cars, and before he went on the road, he went on Huangquan Road, who didn't feel distressed when he saw it?

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

After these cars were reloaded, Liu Xiaodong was used as the company's car distribution and distributed it as a benefit to the company's middle and senior managers.

This is also the first time that a car has been allocated to middle and high-rise buildings, and each person has been issued with a top White Tiger 7 before.

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

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

The rest 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 supporting battery and other things in reality first.

First used his old Poussin as an experiment, and changed it from a fuel car to an electric car.

This is not too difficult for him, but to put it mildly, he is not lightly ill.

You just want to, who would go to the trouble of converting an old Poussin from the last century into an electric car?

But this kind of magical thing happened to him, and it was completely a manifestation of power and nowhere to go.

Starting from the manual preparation of graphene, a pair of batteries, motors and other components began to start.

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

The next thing is to attack his Poussin, and it is at this time that he once again drilled into the virtual laboratory and dismantled his second-hand old Poussin.

Looking at Poussin in the laboratory, the rusty and rotten chassis made him speechless.

This is the general situation that he did not expect, he wanted to transform the car, but this situation happened in the virtual laboratory, fortunately he did not touch the old car in reality.

Looking at the car body and chassis that could no longer be used, a more magical idea sprouted in his heart.

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

And his electric motor now produces 652 horsepower, which is 6.8 times as much, which means that he can transform the car to a maximum of 7.48 tons.

Conservatively, according to 6 tons, he is fully able to transform such a Poussin according to the standard of bulletproof vehicles.

What was originally just a makeshift idea to experiment with batteries and motors made him bigger and bigger.

Then all the new materials that came out before were displayed in front of me, and one of the lightest and strongest materials was selected from it as the shell of the car.

Under his whimsical idea, the shell of the car is made of 0.75mm titanium alloy material, and inside it is a newly developed graphene composite bulletproof insert plate, each with a thickness of one centimeter.

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

And in the middle of these layers, the non-Newtonian fluid theory is also used to make a liquid bulletproof material with special materials, which fills the voids that can only be seen in these layers.

The entire body of the car was brought down by him with an average thickness of three centimeters, and the heaviest door was a terrible fifteen centimeters.

In this way, he changed all the inside of the car, even the tires and wheels were specially made, and the curb weight of the whole car 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 has sacrificed part of the trunk space.

And the lathe glass can't be called glass at the moment, because it's not glass at all.

Rather, 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 brought out by him, and there was no change in appearance on the outside, but on the inside it was very different.

No one would have thought that such an old model from the 80s would be a bulletproof electric car inside.

The car, which originally weighed less than 1.1 tons, now has a total weight of 5 tons, and the space inside the car is three millimeters due to the thickness of the body.

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