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

Xiao Ming agrees with this idea, and only by letting students see and hear can they be inspired.

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

The summer was very hot, but the students still visited one laboratory after another, one factory after another, and one factory after another with the help of the staff of the science and technology park.

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

In the fruit cultivation factory, the students also tasted the fruit cultivated by Pangu Technology, and many students praised it as the purest fruit they had ever eaten in their lives.

The students wore sun hats and lined up in an orderly manner, excitedly discussing the situation of the scene they had just visited.

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

"Great! This is the No. 1 technology company in Xia Country! No, 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 beat Intel and Google. ”

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

"Something just ran by, how I felt a gust of wind. ”

"It's like a car, but there's no figure. ”

"No, the car in the park is running so fast!"

This is officially the Tianhe Micro Nuclear Electric Vehicle Division under the Future Energy Company has just been established in the experimental modified version of the Bidi Tang electric vehicle.

Pangu Technology has set up a project for micro-nuclear electric vehicles earlier today, named Tianhe.

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

There is not a single car in the entire science and technology park, and Tang can be so arrogant in the park, which is even more demanding.

Someone saw the logo of the car with the high-powered camera of the Warwick mobile phone and exclaimed, "Guess what kind of car this is? ”

"Ferrari or Porsche?" replied one student.

"It's Biditun!"

"No, it should be the boss's or executive's car that can drive around the park at will, how can the executive's car be Bidi Automobile? ”

Indeed, after reading correctly, the modified Bidi Tang 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 BYD has been modified to create a small micro-nuclear battery pack, the entire battery pack weighs 100 kg, and is able to provide 400V voltage to the permanent magnet motor, so that it can fully meet the full load operation of the motor.

Zhang Derui followed the test steps to prepare to start the violence test.

The so-called brute force test is to jump the speed of the motor to the highest level, so that it can always consume the energy of the micronuclear battery, and the purpose of this is threefold.

One is to check whether the micro-core battery can stably provide energy for the motor in long-term operation, the other is to check the performance of the BYD electric vehicle motor, and finally to observe the heat dissipation of the motor and battery.

Electric vehicles are not only a means of transportation, but also related to the safety of users' lives, only the entire equipment is tested for violence, in order to accurately test the degree of cooperation between the battery and the motor.

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

The test has been going on for three hours, and if you multiply the speed by the time, the Don has already reached 690 kilometers.

300 kilometers is the watershed of domestic pure electric vehicles in Xia, most of the second-tier manufacturers' pure electric vehicle range can barely reach 300 kilometers, 600 kilometers is also a watershed, only BYD electric vehicles can have a range of 600 kilometers after replacing the lithium battery of Pangu Technology, and Tesla's range is only more than 400 kilometers less than 500 kilometers.

At present, the modified Tang equipped with a micro-nuclear battery has been crazy for 600 kilometers, which fully illustrates the powerful performance of the micro-nuclear battery pack.

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

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

The temperature of the electric motor is rising dramatically, and Tang is equipped with a liquid cooling system, which is logically suitable for permanent magnet motors.

It may be that the motor has not experienced such a crazy run, and after the mileage reaches 1,000, the average stability of the motor has only improved by one degree compared to safety.

Xiao Ming didn't stay in the lab too much and let the experiment continue. This kind of violent experiment has to be tested continuously for at least 10,000 kilometers before it can really explain the problem.

However, it is a pity that Xiao Ming waited less than 10,000 kilometers, and after 5,000 kilometers of continuous high-speed driving, the permanent magnet motor failed, burned out due to overheating, and the experiment had to be terminated.

If the engineers of BYD Auto knew that Pangu Technology was testing the motor in this way, they would definitely vomit blood in anger.

When did Tang's motor experience a violent test of 5,000 kilometers, according to Tang's setting, it ran out of power after 600 kilometers, and it had to be charged.

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

"Burned?"

"It's not enough to burn, but the magnetic properties have also changed, and the performance has been greatly reduced. ”

This is also the disadvantage of the existing motor, there are few engines that will fail when driving 5000 kilometers continuously, but the motor does not rest and continues to work There are really problems.

In fact, the problem is not in the motor of BYD's electric vehicle, but in the experimental method of Pangu Technology.

Using a micronuclear 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 head and said, "Boss, a violent test like this to you, even Tesla's motor will not work." ”

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. It is important to remember that the electric vehicles made by the Tianhe project will be charged in the future, and we must be prepared for users to use electric vehicles for long distances and for a long time, and we must minimize the failure rate. ”

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