The Black Technology Era of Xueba

Possibly influenced by Xiao Ming, the employees of Pangu Technology had a soft spot for Bidi Auto during this period.

Since the boss has put down his body to buy a bidi, then the employees can also drive it! It's fashionable to drive the same car as the boss.

The salesmen of the 4S store in Jiangcheng Bidi have also been a little confused recently. The sales of Tang series electric vehicles, which were not well sold, have soared. This is the contribution of the employees of Pangu Technology.

Xiao Ming bought the bidi electric car not because he was low-key or because he wanted to drive it, but because of modification.

Since Pangu Technology wants to make its own car, it must first understand electric cars. Xiaguo Auto's best Bidi electric car is the best template.

A temporary factory in the Science and Technology Park, where employees of Pangu Technology are dismantling the electric car Tang.

These employees were hired by Pangu Technology a year ago and come from mechanics in after-sales repair shops in major 4S stores across the country.

These mechanics used to work exclusively for Pangu Technology's cars, doing routine repairs and maintenance of cars, etc. Now they have been transferred, and their future work will be to build a new generation of micro-nucleus electric vehicles for Pangu Technology.

Tang's battery is located in the upper right part of the engine compartment, and uses the latest lithium battery from Pangu Technology.

Like Tesla, Tang's uses a battery pack composed of lithium cells.

First of all, the mechanic tested Tang's performance, whether it was acceleration, stability or endurance, it did meet the requirements of participating in the promotion.

Overall, the workmanship of Bidi cars is good.

But in terms of driving experience and riding experience, there is a big gap compared to the more than 200,000 car joint ventures.

And when charging, Pangu Science and Technology Park is reluctantly more convenient because there are places where charging piles can be installed. If you live in a residential area, it will be troublesome. Not every residential area has its own parking space, and not all parking spaces. are allowed to install charging piles.

And even with Pangu Technology's latest lithium battery technology, it still takes five hours to fully charge the battery, and one hour for fast charging.

The car is a means of transportation, and it is used immediately when you need to go out, instead of waiting for the battery to be fully charged.

Imagine that the user's work place is a certain distance from the residence, and he needs to drive every day, and his own home does not have a charging pile, which is very troublesome.

He needs to drive the car to a gas station with charging piles to charge, and then wait for the battery to be fully charged. After a long toss, he can drive away and use it. Since then, the vehicle has lost the meaning of a tool.

This is the reason why pure electric vehicles cannot be promoted, and those who buy plug-in hybrid vehicles will use pure electric power very little in their later use. Most of the time, they still use gasoline power, and plug-in hybrid vehicles are used as For use in pure gasoline vehicles.

The structure of electric vehicles is much simpler than that of fuel vehicles, but the weight of the battery is not small.

Taking Tang as an example, the weight of the whole vehicle is 2.4 tons, which is much heavier than gasoline vehicles of the same level, and the weight of the battery is about 600 pounds.

This design has half the advantages and disadvantages.

The large-volume battery pack can give the electric vehicle enough power, and the weight of the body can also increase the stability and grip of the electric vehicle.

The disadvantages are also obvious. The large-volume battery itself has potential safety hazards.

Whether it is a Bidi electric car or a Tesla electric car, there have been accidents of lithium battery explosions.

The odds of such an accident are not individual, but occur every year.

Once an explosion or natural occurrence occurs, for a single consumer, it may be a car crash.

In addition, the large volume of the battery reduces the space of the electric vehicle, making the whole electric vehicle relatively bulky.

The mechanics dismantled the lithium battery of Pangu Technology. Although the latest lithium battery was developed by Pangu Technology, Xiao Ming himself did not like it.

The mechanics then removed Don's motors and controllers, among other things.

Bidi's permanent magnet motor is indeed a bit distinctive, with a combined maximum power of 180KW and a maximum torque of 330Nm.

The concept of torque is popularized here, that is, the force F multiplied by the force arm S. The greater the torque, the faster the motor rotates, and the faster the motor, of course, the faster the electric vehicle runs.

Then compare Tang's parameters with Tesla's better-selling Model 3, and you can also know Tang's performance.

The Model 3 is equipped with two motors in the front and rear. Both motors have a power of 220KW and a maximum torque of 416Nm.

Because the Tang is an urban SUV, and the Model 3 is similar to a coupe, there is only such a simple comparison between the two, which cannot be qualitatively analyzed.

However, it can also be seen that Tesla's technology is indeed better than Biddy.

Xiao Ming instructed the mechanics to operate on the spot.

After learning about the structure of Bidi Tang, Xiao Ming asked the mechanics to put all the parts except the lithium battery back into the car.

Now it is necessary for the micronuclear battery department of the new material division to develop a supporting micronuclear battery pack for electric vehicles.

Because it is a micronuclear battery, the battery of the battery pack has no battery capacity, and the performance of the battery is expressed in terms of life. The only parameter that measures the metric is the consumption rate of the SiC semiconductor material.

When radiation continuously hits silicon carbide, silicon carbide will also be consumed, and its consumption mainly refers to the consumption of electron color centers that can be captured in the crystal.

The current life of micronuclear batteries is about three years, and the laboratory needs to achieve five years.

The battery is replaced every five years, and the life of a car is about fifteen years, and the battery is replaced about twice.

This is the future of electric vehicles and new energy development.

As for whether the voltage and current output of the battery pack can meet the requirements of the motor, this is a small technical issue.

And based on the current performance of a single (half a fingernail size) micronucleus battery, the volume and weight of the battery pack will be much smaller than that of a lithium battery, which is easy to install and disassemble.

A group of new technical talents also emerged in the experiment. Among them, Zhang Derui, a mechanic from Xiaguo Dongfeng Motor Repair Factory, became the leader of the experimental group because of his technical ability and quick thinking.

Zhang Derui repairs not ordinary cars but armored vehicles, and the mechanical complexity is much more complicated than that of family cars.

Xiao Ming convened the experimental team and the company's senior management to arrange specific tasks.

"We must first make the micronuclear battery an energy source for electric vehicles, and then we will make our own motors, and study our own electric vehicles and driving assistants."

This is obviously a big plan, because Xiao Ming is also preparing to separate the micronucleus battery department from the new material hardware business department.

He said: "The company plans to reorganize Pangu Technology Company into Pangu Technology Group, and become a dedicated future energy company. Future Energy Company will be a wholly-owned subsidiary of Pangu Technology Group, which is mainly responsible for the development of micronuclear batteries and the research and development of future vehicles. "

Xiao Ming took a deep look at Zhang Derui, Zhang Derui raised his chest in high spirits, and finally had his own stage! (I have something to do temporarily, there is only one chapter today, sorry!)
