Reborn Xiangjiang Tycoon Growth
Chapter Eighth White Seventy-One New Car Research and Development 2
In order to adapt to the needs of modern field operations, the U.S. military requires vehicles to be equipped with micro-generators. They also have strong power storage capabilities, which can satisfy a light bulb for 72 hours of lighting without any power; that is, they must store more than 36 degrees of electrical energy.
This is definitely a challenge. Once developed successfully, the safety will be greatly improved when performing tasks in the wild. Small generator technology is relatively simple. After all, humans have been using electricity for more than a hundred years, so it can be said that they are very comfortable with it.
The difficulty lies in the storage of electrical energy. Traditional liquid batteries meet the requirements. However, the weight and size are really appalling, so it is okay for self-driving travel.
Now, American soldiers are driving out to fight, equipped with liquid batteries, which are no different from living targets. General Motors and Ford know that it is difficult to achieve with the existing technology. These requirements are more to make manufacturers including Heiyun Motors give up.
If they withdraw, they can then take the opportunity to ask the US Department of Defense to lower their technical requirements, but Bao Zixuan doesn't think so.
Traditional liquid batteries are not good, so Heiyun Group, which is unique in lithium battery technology, can take over this task. It can even be customized for Heiyun Motors. After all, in terms of lithium batteries, even Japanese manufacturers are technically superior.
Not with the Black Cloud Group.
The U.S. military, and of course the two automakers General Motors and Ford, are destined to shoot themselves in the foot.
Bao Zixuan has been prepared for a long time. Heiyun mobile phone lithium battery department has been seconded to the automobile factory and needs them to work here for a period of time.
The algorithm application of lithium batteries in Heiyun mobile phones is more reasonable, even better than that in the notebook computer department. It is all the credit of Yule Engel; this great figure from Bell Labs is exerting his brilliance in Heiyun Group.
In order to show the importance attached to this military vehicle order, Oblak, the actual head of the mobile phone department, personally led the team. The purpose is self-evident, which is to prove the degree of importance attached.
Bao Zixuan: "Dr. Oblak, these people are all good at developing cars. But when it comes to batteries, especially in the field of lithium batteries, they are blind. You are an expert in this field, let me introduce it to everyone."
Oblak knew all about the teacher's painstaking efforts in arranging for him to come here. Logically speaking, an ordinary engineer could complete it. But why did the teacher send him here? Of course, it was to communicate with Bao Zixuan and let the boss know more about him.
The Heiyun mobile phone department was handed over to him, but I was too young, so this was not the most important thing. I communicated with Bao Zixuan, and the meeting time was too little, and even if I had talent, it was not fully discovered. It is evident that I took advantage of this opportunity.
Yoel Engel also has good intentions.
Engineers, especially top engineers, are just not good at specializing in research. If they were dedicated to being humane and sophisticated, no one in the world could compare with them.
Another point is that true gold is not afraid of fire, and Yoel Engel has absolute confidence in his protégé. Working with Bao Zixuan will definitely allow the boss to fully see Oblak’s technology, organization, and coordination abilities.
Oblak stood up and said: "You are all seniors, and you are absolutely authoritative in the field of car manufacturing. However, this time the US military has requirements for power supply equipment, and our mobile phone company happened to have conducted in-depth research on lithium batteries. We think we can achieve it.
Technical requirements, please correct me if there is anything wrong.”
This is more of a polite statement. No one will take the initiative to challenge other people's authority. Heiyun Mobile Phone is definitely the most profitable company in the group, and it can even be said that there is no other company. Not only does it have the highest market share, but it is also the most expensive.
In this era, mobile phones are regarded as luxury goods. Customers do not pay special attention to price when purchasing. They pay more attention to product performance and services provided. Heiyun has put a lot of effort in this aspect. It even hired fashion designers to design the appearance, which is definitely beyond the times.
.
Oblak: "According to the technical requirements put forward by the U.S. military, traditional liquid batteries simply cannot meet the technical requirements. Because that would require an increase of at least one ton of weight, and the combat performance will be greatly reduced."
"The group has conducted in-depth research and development of lithium batteries three years ago and has now achieved revolutionary breakthroughs."
"Based on the ternary lithium battery used in mobile phones, a lithium iron phosphate battery was developed."
"Lithium iron phosphate battery is a lithium-ion battery that uses lithium iron phosphate as the positive electrode material and carbon as the negative electrode material. The rated voltage of the cell is 3.2v, and the charging cut-off voltage is 3.6v~3.65v."
"During the charging process, some lithium ions in the lithium iron phosphate are detached, transferred to the negative electrode through the electrolyte, and embedded in the negative electrode carbon material; at the same time, electrons are released from the positive electrode and reach the negative electrode from the external circuit to maintain the balance of the chemical reaction. During the discharge process, lithium
The ions escape from the negative electrode and reach the positive electrode through the electrolyte. At the same time, the negative electrode releases electrons and reaches the positive electrode from the external circuit to provide energy to the outside world."
"Lithium iron phosphate batteries have the advantages of high operating voltage, high energy density, long cycle life, good safety performance, low self-discharge rate, and no memory effect."
"If you use a traditional liquid battery, it will weigh one ton to meet the technical requirements of the U.S. military. If you use a lithium iron phosphate battery, the weight will not exceed 50 kilograms."
Hearing this, everyone showed incredible expressions. This kind of sentiment has directly pushed battery technology forward for 20 years or more.
David Bruce, the person in charge of the assembly and an alumnus of Bao Zixuan's MIT, asked: "Dr. Oblak, with such a small size and such a high energy density, how can safety be ensured? If you are hit by a bullet,
Or direct firing of artillery shells, will it bring catastrophic consequences? By then, the parachute incident during World War II may be the black cloud's turn."
This concern is normal. After all, they provide military products. And they provide products for the United States. If their safety performance cannot be guaranteed, there will inevitably be endless troubles.
If the battery explodes, with such a large capacity density, the explosion of the same mortar bomb is almost the same, wouldn't it be very dangerous for the US military sitting on it. Because there is a problem with the product itself, the entire company, including the group's senior managers, will be severely sanctioned.
Moreover, the parachute story is real, and the U.S. military’s requirements for military equipment can be said to be extremely picky.
This is a true story that happened in the middle of World War II between the U.S. Air Force and parachute manufacturers. At that time, the safety of parachutes was not perfect, and the pass rate was only about 60%. After the manufacturers worked hard to improve, the parachute manufacturers
The yield rate of the parachutes produced has reached 99.9%. It should be said that this yield rate is difficult for many companies to achieve even now.
However, the U.S. Air Force said "no" to the company. They required that the yield rate of the parachutes delivered must reach 100%. So the general manager of the parachute manufacturer went to the flying brigade to discuss the matter to see if this level could be lowered? Because the manufacturer believed that it could
At this level it is close to perfection, there is no need to
Of course, the U.S. Air Force refused flatly because there was no discount on quality. Later, the military requested a change in the method of quality inspection. That is to randomly select one of the parachutes delivered by the manufacturer the previous week and let the person in charge of the manufacturer equip it on the back.
I personally jumped off the fuselage in flight. After this method was implemented, the defect rate immediately became zero.
David Bruce previously worked for Jeep and developed and improved weapons for the U.S. military during the Vietnam War. It can be said that he knows the U.S. military quite well. Putting product performance aside, safety is definitely the first priority. Questions raised
It's normal. It's not directed at anyone, it's just a normal work discussion.
Oblak: "You can rest assured about safety; the electrochemical performance of the cathode material of lithium iron phosphate battery is relatively stable, which determines that it has a stable charging and discharging platform. Therefore, the structure of the battery will not change during the charging and discharging process.
, will not burn or explode, and is still very safe even under special conditions such as short circuit, overcharge, extrusion, acupuncture, etc.”
"Not only that, we will also wrap a layer of metal alloy outside the battery casing. Unless it is directly attacked by artillery with a caliber of 100 mm or more, there will be no safety problems. Even anti-tank mines will not be fatal to it.
harm."
"Although it will increase a certain amount of weight, the overall weight will definitely be controlled within 80 kilograms. With various auxiliary equipment, the overall weight of the power system will not exceed 100 kilograms, which will definitely meet the requirements; it will not hold back the entire project."
Oblak holds a doctorate degree in physics and chemistry, and is a well-known teacher. He has high technical requirements, and his guarantee is very important. Not to say it represents authority, but at least it is convincing. If you have any other doubts, just ask
Can be verified through actual testing.
