Cultivate a black technology god

Chapter 120 How can your battery be enough to run a thousand kilometers?

Zhixia Automobile Department under the name of Zhixia Technology, after the launch of the self-driving algorithm, became an independent company in full swing, and started the road of expansion and production expansion.

Everyone in the field of electric vehicles did not start early. Although Spyker of Zhixia Motors just started to develop, more than ten years later than other car companies, but with the escort of the parent company Zhixia Technology, it is just around the corner to become a leader in the industry.

What's more, Zhixia Technology has taken the lead in the autonomous driving industry.

Therefore, Zhixia Automobile Company has a smoother road than any subsidiary of Zhixia Technology.

There is no need for the HR department to work hard to recruit people.

Talents in this field all over the world are jumping to Zhixia Automobile.

No shortage of people, no shortage of money, no errands, and the speed of development is frightening.

After discussion by the company's department, Spyker's battery can't be expected to do a little research on its own. At this stage, it is more reliable to buy it directly.

Xia Zhi's office.

In front of Xia Zhi were the cooperation plans of major battery manufacturers.

This proposal was sorted out by secretary Xiaomei and operation officer Sun Shiliang working overtime, and it was waiting for Xia Zhi to make a decision on which manufacturer to cooperate with.

Xia Zhi looked at the thick pile of documents, frowned and said:
"Old Sun, tell me what you think."

Sun Shiliang has done enough homework in this area before, and now he will open his mouth to express his opinion:

"When it comes to making electric vehicles, Japan's Toyota was the first. They launched hybrid models in the 80s. So far, they have more than 700 patents on batteries. There is nothing to say about the technical reserves, and then GM, but the market The highest evaluation on the Internet is Tesla abroad, as well as domestic BYD, Ningde era, etc. Needless to say, Tesla, BYD used to make a fortune in batteries.”

Sun Shiliang gave an eloquent introduction for more than ten minutes, but at the end he didn't say which one was better.

In summary, each has its own advantages.

In the end, Xia Zhi chose domestic BYD.

BYD has recently been worrying about overseas sales channels.

If you hold the thigh of Zhixia Technology, you can say anything.

It just so happens that there is a battery processing plant built by BYD in Jinling.

Xia Zhi took Sun Shiliang to drive there.

The BYD battery factory came to meet Xia Zhi with the director of the factory, his secretary and the chief engineer of the factory.

Under the leadership of the chief engineer, Xia Zhi and the others visited BYD's battery factory.

Seeing that Xia Zhi was quite satisfied, the factory manager smiled and said:

"Our BYD is different from Ningde era. We generally do not cooperate with other manufacturers, but for Zhixia Technology, we have great enthusiasm and look forward to cooperating with your company. We can not only provide batteries, but also in other automotive technologies, BYD I am also willing to give my all.”

Xia Zhi was a little surprised. He glanced at the factory manager and asked:

"You, a small factory manager, can make this decision?"

The factory manager said with a smile:

"Since the chairman of the company sent me to entertain you, he naturally greeted you in advance."

Xia Zhi lamented that these manufacturers were too generous.

However, considering the current influence of Zhixia Technology, other manufacturers either choose to follow or be eliminated. It seems that there is no other way to choose.

Xia Zhi nodded and said:

"Your production line is very formal. Take me to see your latest battery products."

The factory manager hurriedly asked the chief engineer to lead the way, and at the same time introduced to Xia Zhi:
"The blade battery that our factory is currently researching, the nearly 1-meter-long pole piece, can achieve tolerance control within ±0.3mm, and the accuracy and speed of single-chip stacking efficiency at 0.3s/pcs, which is the first of its kind in the world. This kind of lamination uses equipment and cutting solutions completely independently developed by BYD, which cannot be copied by anyone else."

While talking, they came to the product department.

Xia Zhi asked the person in charge here:
"How long is the service life of your new product, and will the cruising range decrease with the increase of the number of years? There are also battery maintenance issues, please introduce them to me."

As he spoke, he glanced at the technician he had brought over.

Instruct them to take notes.

After all, Xia Zhi himself does not understand battery technology.

The person in charge of the product responded to Xia Zhi's question:

"First of all: we use 80-degree lithium iron phosphate batteries. In the case of fast charging twice a day, the attenuation will reach 2% in about 3 years and must be replaced. A lot of slow charging, a small amount of fast charging, after 40 years, The battery attenuation is about 3%-15%. It is expected to reach 20% in about 5 years.

Our quality assurance policy is: "The main components of the electric system are repaired for 8 years or 15 kilometers, mainly including power motors, drive motor controllers, DC assemblies and batteries (except for batteries). The batteries are guaranteed for life .

Moreover, lithium batteries have attenuation, and the life cycle is determined according to the number of times the battery is charged and discharged.The cruising range will decrease as the battery decays.

As for maintenance, the power lithium battery does not need to be maintained, and there is no need to change the oil or spark plugs.It is the charge and discharge test, and then see if there is any appearance damage.The maintenance of new energy vehicles is to refresh the program, read the data, and check the tire and brake pads.We maintain a certain new energy vehicle under our name, and we can maintain one in 15 minutes. "

After Xia Zhi listened to the introduction, he glanced at the technicians he had brought.

They nodded.

Xia Zhi didn't ask any more questions, and proposed to take BYD's products back to study.

Normally, no battery manufacturer would agree to such an unreasonable request.

But the factory manager was very enthusiastic and asked the chief engineer to pack the product according to Xia Zhi's request, and personally delivered it to Xia Zhi's car.

In addition to products, there are materials for technical explanations.

In addition to the BYD battery factory that Xia Zhi went to personally, Zhixia Technology also brought battery samples from various factories in the market for testing.

The test is not in a laboratory. This kind of car battery still has to be put in the car and driven on the road.

Xia Zhi asked Sun Shiliang to arrange manpower and vehicles, install batteries from various manufacturers, and then hit the road.

There are test vehicles for various road conditions, such as urban roads, smooth and traffic jams, highways, and country roads.

After a week of testing, Xia Zhi got the test report from the technicians and called the BYD factory manager:

"How can your battery run a thousand kilometers?"

The factory director quickly explained:

"This is the peak time that can be reached under the most suitable conditions. Normally, it is [-] kilometers to [-] kilometers."

Xia Zhi had a few words with the factory manager, and then asked his technicians to negotiate with them.

No matter what, you still have to choose the purchasing manufacturer in the end.

However, Xia Zhi felt that their battery technology was too backward and the development speed was unsatisfactory.

He couldn't keep up with the smart city plan he had planned, so he decided that the battery technology should be made by Xia Technology.

Xia Zhi can accept three system tasks at the same time.

What is being done now is the traffic dispatching algorithm activated after the completion of the automatic driving algorithm, and the operating system that has been working.

The third task option, after finishing the game engine before, has been empty.

Now it is just used to brush battery technology.

Thinking of this, Xia Zhi accepted the task, and a third task panel appeared in his mind:
[Mission in progress: battery technology. 】

[Development time: 0 days]

[Energy input: 0 points]

[Investment funds: 0 points]

[External assistance: 0 points]

[Total mission points: 0 points]

[Note: The minimum points required to enable system assistance: 100 task points. 】
