Chapter 430: Brute force test

Due to the friendly application of the relevant departments of Jiangcheng, during the summer vacation, some of the laboratories of Pangu Science and Technology were open to primary, middle and primary school students.
Xiao Ming agrees with this idea. Only by letting students see and hear can they be inspired.
Maybe that elementary student wants to become a great scientist after seeing Pangu Technology's biological laboratory.
The summer is very hot, but the students still visit the next laboratory, a laboratory, a factory, and a factory in the science park.
This time, Pangu Technology opened a total of two laboratories and an experience point and a factory-a chip laboratory, a life science laboratory, a virtual reality experience point for the future product division and a fruit production plant.
In the fruit cultivation factory, the students also tasted the fruit cultivated by Pangu Technology. Many students praised that this is the most pure fruit in this life.
The students, wearing sun hats, 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 given students a strong touch.
"Great! This is Xia Guo's number one technology company! No no no! World No. 1!"
"I have never used Pangu's products before, but this time I visited their laboratories and factories, and now I understand why Pangu is successful! It is definitely capable to beat Intel and Google."
At this moment, a white shadow flashed, and the visitors looked sideways.
"Just passed something, how could I feel a gust of wind."
"It looks like a car, but there is no figure."
"No, the cars in the park run so fast!"
This officially Pangu Technology has just established the Tianhe Micronuclear Electric Vehicle Division of Future Energy Company, which is an experimental modified version of BiDi Tang electric vehicle.
Pangu Technology has initiated a project on micronuclear electric vehicles earlier today and named it Tianhe.
"Really! Really a car!" The visiting students saw white shadows 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, it is even more demanding.
Someone used the high-power camera of the Warwick mobile phone to see the logo of the car and exclaimed: "Guess what kind of car is this? Actually driving in the park at such a fast speed."
"Ferrari or Porsche?" Some students answered.
"It's Bidtang!"
"No, it's the car of the boss or the executive who can drive freely in the park. How can the executive's car be a Bidi car? Make sure you read it right."
Indeed, I read it right. After the modified Bidi Tang electric car entered the garage after testing, Zhang Derui extinguished the cigarette butts in his hand and instructed the workers to drive Tang on the operating platform.
This Bidi battery compartment has been modified to create a slightly modified micro-core battery pack. The entire battery pack weighs 100 kg and can provide a voltage of 400V for a permanent magnet motor, which can fully meet the motor's full load operation. .
Zhang Derui prepared to start the violent test according to the test steps.
The so-called violent test is to jump the speed of the motor to the highest level and let it always consume the energy of the micro-core battery. There are three purposes for doing so.
One is to check whether the micro-core battery can stably provide power to the motor during long-term operation, the other is to check the performance of the Bidi electric vehicle motor, and finally to observe the heat dissipation of the motor and battery.
Electric vehicles are not only a means of transportation, they are also related to the safety of the user's life. Only by performing a violent test on the entire device can the accuracy of the battery and motor be tested.
At this time, the overhead Tang speed reached the best 230KM / h. Only the pure electric version has this speed. The maximum plug-in speed is only 180KM / h.
The test has lasted three hours. If speed is multiplied by time, Tang's driving journey has reached 690 kilometers.
300 kilometers is the watershed for Xia Guo's domestic pure electric vehicles. The battery life of most second-tier manufacturers can barely reach 300 kilometers. 600 kilometers is also a watershed. Only the Bidi electric vehicle in the world can have 600 kilometers after replacing Pangu Technology's lithium battery. Tesla's battery life is only 400 kilometers and less than 500 kilometers.
At present, the modified Tang equipped with a micro-core battery has run madly for 600 kilometers, which fully illustrates the powerful performance of the micro-core battery pack.
Bidi Tang's permanent magnet motor still has good performance and can not fail after 600 kilometers of gallop.
However, the monitor of the experimental group found some problems.
The temperature of the motor is rising sharply. Tang is equipped with a liquid cooling system. It is reasonable to say 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 reached one thousand, the average stability of the motor has only increased by one degree than the safety.
Xiao Ming did not stay too much in the laboratory, allowing the experiment to continue. This kind of violent experiment has to be continuously tested for at least 10,000 kilometers to be able to really explain the problem.
Unfortunately, UU reading www. uukanshu.com Xiao Ming waited less than 10,000 kilometers. After 5000 kilometers of continuous high-speed driving, the permanent magnet motor malfunctioned and burned out due to overheating. The experiment had to be terminated.
If Bidi's engineers knew that Pangu Technology would test the motor in this way, it would definitely spit blood.
When did Tang's motor experience a 5,000-kilometer violent test, according to Tang's setting, running for 600 km would run out of power and must be recharged. While charging, the motor also had a rest.
"The performance of the motor has dropped sharply." Xiao Ming got the news from the laboratory.
"Burned?"
"It won't burn it, even the magnetic properties will change, and the performance will be greatly reduced."
This is also a disadvantage of the existing electric motors. Few engines will fail after 5,000 kilometers of continuous driving, but the motors continue to work without rest and really have problems.
In fact, the problem is not with the motor of Bidi's electric vehicle, but with the experimental method of Pangu Technology.
Using micro-core batteries to supply sufficient energy to allow the motor to travel 5,000 kilometers at full load, this performance is actually quite good.
"The motor doesn't work," Xiao Ming said.
Zhang Derui covered his head and said, "Boss, a violent test against you, not even Tesla's motor."
Xiao Ming did not agree with Zhang Derui. He said: "The power of the battery will increase, and our requirements for the motor will also increase. Remember that the electric vehicle made by the Tianhe project will be recharged in the future. Ready users to use electric vehicles for long distances and long hours, we want to minimize the failure rate. "
Prior to this, the future energy company has networked a large number of mechanical talents from all over the world, and they will find ways to improve the motor.
