? Compared with ordinary lithium batteries, the performance of graphene batteries has indeed made a big leap forward. No wonder these technicians who are usually very calm are so excited, as if they have won a battle.
? Graphene¡¯s electrical conductivity is unparalleled in the world. Let¡¯s not talk about this. Its energy density has increased by 4 times.
What is this concept?
An electric vehicle with a range of 500 kilometers has four times the electrical energy storage of the same size and a range of 2,000 kilometers.
??????????? ?????????????????????????????????????????????????????????????????????????????????????????????????????????? When I¡¯m running back and forth from Zhonghai to Beijing, I almost don¡¯t need to charge it.
There is nothing to worry about on the battery side. The brothers on the team will take care of it. Now, Chen Yao and Zhang Zhenhong go to the car factory to have a look.
The automobile factory is located near the battery factory, covering an area of ??more than 3 million square meters. It is divided into three phases of construction. The first phase of the factory has been completed.
Relevant local departments attached great importance to it and obtained the right to use this industrial land at a very low price.
It is almost impossible for fuel vehicles to defeat foreign car manufacturing giants, and all countries around the world have introduced plans to withdraw fuel vehicles. In about twenty or thirty years, fuel vehicles will be completely replaced by electric vehicles.
This is a great era. Whether domestically produced cars can achieve overtaking in corners depends on electric cars, and we attach great importance to them from top to bottom.
Chen Yao and Zhang Zhenhong walked into the factory and saw a driverless car approaching at first sight.
?You can see through the glass window that it is empty and there is no driver. He is driving forward along the designated route, turning and avoiding obstacles.
The speed was not very fast, so Chen Yao walked over and stood in front of the car, and the car swerved around it very intelligently.
"Yes, the car is quite intelligent." Chen Yao smiled and nodded.
The team that develops driverless cars is from the AI ??Automotive Institute of Shenzhen University. They have very good technical capabilities in making driverless systems. The team is led by Zhong Guoqiang, a well-known artificial intelligence professor in China.
"Thank you for your hard work, Professor." He walked towards him, and Chen Yao handed him a bottle of ice spring.
On this hot day, instead of staying indoors and blowing on the air conditioner, he went outdoors to do tests. The old scientist is really a model worker.
Zhong Guoqiang took the ice spring, unscrewed the bottle, took a sip, looked at the car that was driving unmanned, and said: "The driverless system has been built, and the test data in all aspects are good, but there are still many problems. question."
Chen Yao thought for a while and asked: "Have you achieved L4?"
Self-driving cars are divided into five levels, from L1 to L5. Most of the self-driving cars on the market have only reached L2, which is the assistance level, and cannot yet replace human driving.
The L3 is better, but the L3 autonomous vehicle has not yet been mass-produced, and even if it is, it still requires human participation.
If you want to achieve true driverless driving, you must at least reach L4, and the most awesome one is L5.
When you go out in the morning and lie down in the car to sleep, and the car takes you downstairs to the company, you are still safe. No matter how complicated the road conditions are, no one is required to drive the whole journey.
At present, no company in the world has been able to build the L5 self-driving car. It is just a beautiful black technology that only remains in fantasy.
If you want to realize driverless driving, there are two main modules, one is the sensor and the other is the intelligent algorithm.
But sensor technology has come to an end, and there are no big breakthroughs at present. Whether it is lidar, ultrasonic radar, millimeter wave radar, or infrared, they all have their own advantages and disadvantages.
Moreover, the disadvantages are very obvious and there is no good solution.
For example, an autonomous car is driving on the road and suddenly a red plastic bag blows over.
The laser radar senses that this is an obstacle and it will immediately brake urgently.
But it¡¯s obviously just a plastic bag. Why don¡¯t you put a bird egg in it?
If a human being can tell it, isn¡¯t it just a plastic bag? There will be no problem if you just drive past it.
But the sensor is so rigid. It cannot judge whether the object in front of it is dangerous like the human brain can?
Even Tesla President Musk said that if you want to dismantle lidar, the actual effect of this thing is not obvious, and it is high cost and bulky.
There are many problems with sensors, so the second option is to use cameras to collect road scenes and then analyze them with intelligent algorithms.
This method is relatively close to human driving, and the cost is extremely low. It only requires a camera, but the problem is that there are still many problems.
¡°In addition to convenience, self-driving cars are more importantly for safety,¡±??There will be times when judgments are wrong when driving. It is unreliable to rely solely on cameras to collect scene calculations to ensure driving safety.
Zhong Guoqiang took a sip of ice water and said: "Currently, what we have achieved is only l3, and l4 is still in the theoretical stage."
Chen Yao pursed his lips and thought for a while: "It's not bad to be able to achieve L3. Mass production of it is better than many autonomous vehicles on the market."
The driverless system is not planned to be implemented in one step, nor can it be implemented in one step. The most critical thing at present is to mass-produce electric vehicles and launch them on the market as soon as possible.
Many companies that make electric vehicles have made little noise and have been working on them for many years without even a single mass-produced vehicle.
The first generation of legendary electric vehicles focused on hardware, quickly seizing the market with powerful hardware performance.
Zhang Zhenhong smiled and said: "Professor, I have good news for you. Our graphene battery has made a major breakthrough and will be mass-produced soon!"
"Really?" Zhong Guoqiang's old face showed a look of joy.
The core competitiveness of electric vehicles lies in the battery. A breakthrough in battery technology is a major victory. Even a new brand can get a large number of orders.
"Yes, it's done." Chen Yao told him with certainty.
"Okay, I know there's nothing you can't handle." Zhong Guoqiang laughed happily.
The electric car circled around the green belt, then slowly drove back and stopped in front of the three people.
In front of the front of the car, there is only the word "legend".
Zhong Guoqiang asked: "Is your car called Legend Car?"
Chen Yao shook his head slightly: "I haven't thought of a name yet. Do you have any good suggestions?"
Zhang Zhenhong blurted out: "Why don't we call it 'Chen Yao Automobile'. You are the founder of the automobile company, so let's name it after you."
Isn¡¯t there a Xpeng Automobile in China? It¡¯s the founder¡¯s name.
Chen Yao shook his head and immediately rejected it: "No, change it."
I always feel that using one¡¯s own name to name something is more like what foreigners do. This naming method is actually not good for the company¡¯s brand.
??Chinese culture is vast and profound, and there are so many words that can be combined, so why bother learning from foreigners?
Zhong Guoqiang asked: "Then what name do you think is suitable?"
Chen Yao picked up a piece of chalk and wrote four big characters on the front of the car. (Remember the website address: www.hlnovel.com
