The Black Technology Era of Xueba

Due to the friendly application of relevant local departments in Jiangcheng, some laboratories of Pangu Science and Technology are open to students of primary and secondary schools during the summer vacation.

Xiao Ming agrees with this idea. Only by letting the students see and hear it can they be inspired.

Maybe the elementary school student will be inspired to become a great scientist after seeing the biological laboratory of Pangu Technology.

The summer is very hot, but the students still visit the next lab, one lab, one factory, one factory with the staff of the Science and Technology Park.

This time, Pangu Technology has opened a total of two laboratories, one experience point and one factory - a chip laboratory, a life science laboratory, a virtual reality experience point of the Future Products Division and a cultivation fruit production factory.

In the factory that cultivated fruit, the students also tasted the fruit cultivated by Pangu Technology, and many students praised that this is the purest fruit that they have eaten in their life.

Students wearing sun hats lined up in an orderly line, excitedly discussing the situation of the scene they just visited.

The scenes of the laboratory and the virtual reality experience point have given the students a strong touch.

"Fantastic! This is the number one technology company in Xia! No no no! No. 1 in the world!"

"I have never used Pangu Technology's products before, but this time I visited their laboratory and factory, and now I understand why Pangu Technology is successful! It must be powerful to be able to beat Intel and Google."

At this moment, a white shadow flashed by, and the visitors looked sideways.

"Something ran just now, how could I feel a gust of wind."

"It seems to be a car, but why is there no figure."

"No way, the cars in the park run so fast!"

This is officially the modified version of the Biditang electric vehicle that Pangu Technology has just established under the Tianhe Micronucleus Electric Vehicle Department of Future Energy Company.

Pangu Technology has set up a project for a micronucleus electric vehicle earlier today, named Tianhe.

"Really! It's really a car!" The visiting students saw a white shadow on the field not far away, and Tang's form slowed down.

There is no car in the entire science and technology park. Tang can be so arrogant in the park, which is even more demanding.

Someone saw the sign of the car with the high-powered camera of the Huawei mobile phone and exclaimed: "Guess what car this is? It's actually driving at such a fast speed in the park."

"Ferrari or Porsche?" a student replied.

"It's Bidi Tang!"

"No way! It should be the boss or the executive's car that can drive freely in the park. How can the executive's car be a Bidi car? I'm sure I'm not mistaken."

It is true that the modified Biditang electric car entered the garage after the test. Zhang Derui snuffed out the cigarette butt in his hand and instructed the workers to drive Tang on the operating table.

The battery compartment of this Bidi has been modified to create a slightly modified micronucleus battery pack. The entire battery pack weighs 100kg and can provide a voltage of 400V for the permanent magnet motor, which can fully meet the full load operation of the motor. .

Zhang Derui prepared to start the violent test according to the test steps.

The so-called brute force test is to jump the speed of the motor to the highest and let it consume the energy of the micronucleus battery all the time. There are three purposes for this.

One is to check whether the micronucleus battery can stably provide energy to the motor during long-term operation, the other is to check the performance of the Bidi electric vehicle motor, and finally the heat dissipation of the motor and the battery is observed.

Electric vehicles are not only a means of transportation, but also related to the safety of users' lives. Only by violently testing the entire device can the degree of cooperation between the battery and the motor be accurately tested.

At this time, the overhead Tang speed reaches the best 230KM/h, only the pure electric version is this speed, and the plug-in hybrid top speed is only 180KM/h.

The test has been going on for three hours, and if the speed is multiplied by the time, the Tang has already covered 690 kilometers.

300 kilometers is a watershed for Xiaguo's domestic pure electric vehicles.

The battery life of most second-tier manufacturers' pure electric vehicles can barely reach 300 kilometers, and 600 kilometers is also a watershed. In the world, only Bidi electric vehicles can have a battery life of 600 kilometers after replacing the lithium battery of Pangu Technology, and the battery life of Tesla is only 400 kilometers. less than 500 kilometers.

At present, the modified Tang equipped with the micronucleus battery has gone crazy for 600 kilometers, which fully demonstrates the powerful performance of the micronucleus battery pack.

Biditang's permanent magnet motor still has good performance and can run for 600 kilometers without failure.

However, the monitors of the experimental group still found some problems.

The temperature of the motor is rising sharply, and Tang is equipped with a liquid cooling system. It stands to reason that this cooling method is very suitable for permanent magnet motors.

It may be that the motor has not experienced such a crazy run. After the mileage reaches a thousand, the average stability of the motor has only improved by one degree compared to safety.

Xiao Ming did not stop in the laboratory too much and let the experiment continue. This kind of violent experiment, at least continuous testing of more than 10,000 kilometers, can really explain the problem.

Unfortunately, Xiao Ming waited for less than 10,000 kilometers. After 5,000 kilometers of continuous high-speed driving, the permanent magnet motor failed and burned out due to overheating. The experiment had to be terminated.

If the engineers of Bidi Automobile knew that Pangu Technology used this method to test the motor, they would definitely vomit blood.

When did Tang's motor undergo a violent test of 5,000 kilometers? According to Tang's settings, it ran out of power after 600 kilometers and had to be charged. While charging, the motor also got a rest.

"The performance of the motor has dropped sharply." Xiao Ming got the news from the laboratory.

"Burned?"

"It's not so bad if it burns, even if the magnetism changes, and the performance is greatly reduced."

This is also the disadvantage of the existing electric motor. Few engines will fail after driving for 5,000 kilometers continuously, but the motor will really have problems if it does not rest and continue to work.

In fact, the problem is not the motor of Bidi electric car, but the experimental method of Pangu Technology.

Using the micronucleus battery to supply sufficient energy to allow the motor to travel 5,000 kilometers at full load is actually quite good.

"The motor doesn't work," Xiao Ming said.

Zhang Derui covered his forehead and said, "Boss, even a Tesla motor can't do a violent test like yours."

Xiao Ming did not agree with Zhang Derui's opinion. He said: "The power of the battery will become larger and larger, and our requirements for the motor will also increase. Remember, the electric vehicle made by the Tianhe project will be charged in the future. To prepare users for long-distance and long-term use of electric vehicles, we want to minimize the failure rate."

Prior to this, Future Energy has networked a large number of mechanical talents from all over the world, and they will find ways to improve the motor.
