Coquettish Rebirth

Jia Hongjian quickly approved such a plan, and he will not be required to do the next thing. The children below will contact the corresponding manufacturers soon to see if they can design a corresponding robot, and See how much it will cost to produce robots by then.As for Jia Hongjian himself, he has other things to pay attention to for the time being—now Ding Haitao is making an international long-distance call to his master Guo Konghui, and is using all kinds of exaggerated language to describe the electric SUV they experimented with! "Master Emma, ​​that car is amazing! We haven't done any optimization, but relying on the electric control provided by Tesla and the 1 with more than 18650 knots, the battery life is almost 400 kilometers! Then The accelerator is coming fast, and there is no sound! When driving, there is only tire noise and wind noise, and the buzzing sound of the electric motor is much quieter than that of the engine..."

In Ding Haitao's description, this electric car is really cool!It's really cool. Although Ding Haitao, as a car practitioner, has long known the characteristics of the electric motor, such as fast speed increase and low noise, but he really didn't know the difference until he tried it himself!For example, when an ordinary car stops and waits for a red light, although the car stops, the engine is still idling, so in fact, the car still vibrates slightly at such a time, but everyone is used to it. Realize it.But when I switched to an electric car, I stopped the car and waited for the red light, but I could clearly feel that the car didn't vibrate at all!Even when starting, stopping or running, the car didn't vibrate at all!At most, there is a thin humming sound unique to the electric motor when the car is driving, just like the sound of an amplified electric car when it is driving!

Compared with the engine noise of a gasoline engine car running, such a sound is so silent!At the same time, the electric motor accelerates much faster than the gasoline engine. There is no optimization at all, and there is no special customization for the electric motor.As a result, the acceleration from 7.8 kilometers to 6 kilometers for such a suv temporarily modified with a van chassis unexpectedly reached [-] seconds in less than eight seconds!If we go back and optimize it, redesign the chassis, and then redesign the car shell, and even take the car shell to the blower hole to create a shape with less wind resistance, can the acceleration from [-] kilometers be increased quickly?Can the data of acceleration from [-] kilometers to [-] seconds be more than [-] seconds?At that time, the acceleration is absolutely exaggerated!Like a Mercedes-Benz S-Class.Acceleration data is just such a level!It can be said that if it is changed to an electric motor, Huaxia Hi-Tech, which is far inferior to foreign giants such as BMW and Mercedes-Benz in terms of engine technology, can at least reach the same level as the other party in an instant-although the electric motor is still outsourced, but At least we can buy it!For example, if we want to make a gasoline engine, if we want to buy a good Mercedes-Benz engine, no one will be willing to sell it to us, okay?

After all, Mercedes-Benz makes cars and researches engines by itself. Of course, they are not willing to sell engines to potential competitors!But for a brand like Tesla that buys electric motors, Wanwan Tomita only makes electric motors.Not a car!So people sell motors to anyone!Even when people saw that we were going to use their electric motors to make cars, they rushed over to curry favor with us!Because we are big customers!Even in the future, it is not impossible to actively develop and tackle related technologies according to our needs, and actively develop new products that meet our requirements!At that time, the data will be better if it is not good?And they will never get stuck on us!Even when the time is right, it is not difficult to acquire this company, or at least acquire a part of the shares!

Originally, Guo Konghui and the older generation didn't quite believe that electric cars could be handled in such a simple and child's play these days.Because it was originally the 90s.That's when the first gasoline-electric hybrid car appeared!According to the truth, after more than ten or 20 years of development time.The future should be the time when gasoline-electric hybrid vehicles show their prowess, right?After all, according to the understanding of ordinary people, technological progress should be gradual and should come step by step.After a pure gasoline engine, it should be a gasoline-electric hybrid, and after a major breakthrough in battery technology, it will be a pure electric vehicle!After all, the biggest problem in modern technology is battery technology.Although lithium batteries and other things have appeared, the energy density of batteries has not yet broken through, which has caused batteries to be the bottleneck of many new products in many cases!

In the eyes of the old men, 18650 lithium batteries should not be used as car batteries!Because on the one hand, it's all thousands of batteries put together.Are you kidding me?It's like playing house with a child. Is this safe?Does this effectively solve the consistency problem?They just haven't bothered to fix the consistency issue because they're not into batteries!What they are thinking now is to wait for the emergence of fuel cells or batteries with higher energy density in the industry before preparing for electric vehicles.But who would have thought that such a toy-like electric car that Jia Hongjian and the others just made up casually now would actually work!Although this kind of "really good" does not mean that it can be directly listed, but that it can be driven, and it can pass the test of continuous driving for a week!

This surprised the old men all of a sudden!This immediately made the old men want to try it!After all, they all know that if they can really do this, they will be able to make Huaxia Hi-Tech's own electric car in the future, even if it is hung under the Tesla brand, that would be a big improvement!At that time, it will be able to overthrow the automobile market just as the smartphone made by Huaxia Hi-Tech has overturned the table of the traditional mobile phone market!Even if the power of various giants is too great, and others can learn how to use lithium batteries in this way, it can make Huaxia Hi-Tech's automobile department enter the world's top level all of a sudden!How much progress is this?

So all of a sudden, the domestic automobile department immediately recruited staff and started experimenting.Of course, their experiment is not just like Jia Hongjian and the others in North America, using the chassis of other cars to temporarily install electric motors and batteries to try to run the field. Get a car in order for a car that can be launched!That's right, this time they experimented, that is to redesign from the chassis!This time they redesigned a chassis suitable for suv, leaving the position of the motor and the battery box specially used for storing the battery, and even specially made a titanium alloy armor plate rigidly connected with the chassis on the chassis!In particular, old men like Guo Konghui are very worried that the bad road conditions in the Chinese countryside will cause stones on the dirt road to scratch the chassis and hit the battery, so this armor plate is made into a V-shaped chassis!

The practice of this V-shaped chassis is learned from things like armored vehicles and foreign explosion-proof vehicles!In order to prevent ordinary landmines targeting personnel from causing damage to the chassis of armored vehicles, some armored vehicles and foreign explosion-proof vehicles have a V-shaped armor plate on the bottom of the vehicle to prevent the impact from being too large during blasting. !Of course, such an armor plate is impossible to defend against anti-tank mines, it can only defend against mines aimed at personnel.After all, anti-tank mines have made great progress these years. If nothing else, the principle of rpg and armor-piercing projectiles in tank shells is incorporated into anti-tank mines, so that when anti-tank mines explode, energy is released in a targeted manner. , the energy melts the metal cone placed on the blast surface, turning the metal cone into a fiery molten metal heat flow that is pushed upward by the energy of the explosion. Is this the tank chassis armor that is tens of millimeters thick?Not even mentioning the penetration depth of modern high-tech armor-piercing shells, even the armor-piercing shells a few years after World War II can penetrate more than 300mm of vertical homogeneous steel armor!Otherwise, why would the European tank designers collectively let the Leopard 1 tank and the French tank not be armored?It was because at the time I felt that it was useless to have armor, and I would still be pierced. It would be better to run faster without armor and not get hit!

Of course, the V-shaped chassis is used. Our car is not for mine protection, but for some rural dirt roads with low sides and high middle. In this road condition, the high ground in the middle is still pierced by protruding stones. To cut through the chassis, V-shaped chassis armor is really needed!On the other hand, because our car is not a front engine of a traditional gasoline engine car, there is no need for a long drive shaft under the chassis to transmit power to the rear wheels!In our car, the electric motor is at the position of the fuel tank, in other words, there is actually a gap under the seats where the rear passengers sit, which happens to be located near the top of the rear wheels, so our car does not have a drive shaft .In such a case, the chassis of the car is actually flat!Get a V-shaped chassis armor, the angle does not need to be too big, just like the space occupied by a drive shaft under the chassis of a general car, then it will do!In this way, even if there are sharp stones under the chassis, it will not make the driver who is used to ordinary cars misjudge the passability of the car. Our chassis protrudes a little bit more, and it will be bad if it scratches the chassis.

In addition to the chassis, the designers of Huaxia Automobile also quickly designed a passable-looking SUV body shape, and even designed the interior of the car together.It can be said that everything is to test whether such a suv car can really be manufactured as a commercial car, and whether it can really guarantee safety under various collision conditions!It can be said that it was because Jia Hongjian and the others played around with such an electric experimental car that all the old men who were opposed to electric cars were willing to try it!
