hear battery,

Wang Fan's heart moved, as if he thought of something, but there was still a little doubt in his heart:

"What functions does the small aircraft you designed have? How come an ordinary power supply cannot support it within 1/3 of the time?"

"Even if the aircraft's consumption is relatively high, this is a bit abnormal."

"Let me think about it, it's a little more."

Tao Wei clasped his fingers and counted items one by one:

"Ultrasonic sensor, this is used to measure distance."

"Laser sensor, like ultrasonic, has precise distance."

"Optical sensors, transmit images, and establish remote sensing pictures."

"…………"

Tao Wei popped out eight sensors from his mouth in succession, and explained the application of each sensor on the aircraft.

After hearing this, Wang Fan felt numb and the answer came out.

good guy,

No wonder the power supply is insufficient.

The question of love is here.

Eight sensors were directly attached. Even the silly son of a landlord would not dare to do this.

Such a large energy consumption,

It's strange that ordinary power supplies can be used. It even scolded the owner of a Taobao store, who didn't even know what was wrong.

Generally speaking,

Small Bishu aircraft like this are equipped with only two sensors and a driving system, just like ordinary Bishu small aircrafts.

And Tao Wei's is obviously not ordinary, it is clearly the plus version.

eight sensors,

Even if it is a group of four, two types of drivers must be used.

After all, sensors such as optical and ultrasonic, remote sensing and ranging, belong to two completely different types, and the gap is too big.

If you use the same set of driver systems, it is possible. It is just a matter of adding more interfaces to the program. However, the overall control system, that is, the stm32 microcontroller, will face a very large operating load and will easily crash midway.

"That won't work either."

Tao Wei listened to Wang Fan's words and said plausibly:

"It cost me more than 100 yuan. My boss assured me that there will be no problem with my graduation project. If I fail, I will be fined 10 yuan. I have to have a good argument with him."

"I'm not saying that the energy density of current batteries is just not good enough."

"Too low!"

Tao Wei extended the topic, as if he was worried about the country and the people:

"Take the most advanced DJI drones and BYD cars in China that use batteries as the main energy source. The former and best series of drones can only fly for 55 minutes when fully loaded."

"Although the latter one has a blade battery as a load, the battery life still cannot exceed 700 kilometers. If it encounters extremely cold weather, it has to be discounted from the original basis. A 400-kilometer range from 700 kilometers is considered good."

After complaining a few words, Tao Wei patted Wang Fan:

"Wang Fan, you are in the energy materials business, so I have to rely on you from now on."

"When will a new material be developed that can solve all the above problems at once?"

"I see that the research direction of your graduation project is very good. With materials of that level, once there are results, it will be a world-class discovery. By then, I will be able to get some light from behind."

The more Tao Wei talked, the more energetic he became. In the end, he imitated the character in the TV series Water Margin and clasped his fists: "We want to be rich and noble, but don't forget each other."

Wang Fan: "Dogs are rich and noble, and they bark at each other!"

Then, Wang Fan walked into the room, and under Tao Wei's somewhat unclear gaze, he took out a silicon carbon negative electrode material battery:

"Try this."

"See how long it can run?"

Tao Wei's face was full of doubts. He looked at the dark stone-like thing on the table:

"What's this?"

"Don't tell me this is a battery."

"Congratulations, you got the answer right!"

"It's really a battery. I've never seen such a strange battery in my four years of college."

Tao Wei was a little surprised and a little unexpected.

But it’s not his fault. The handmade battery really doesn’t look good. It looks like freshly cooked black charcoal, with white lines on it. People who don’t know it think it’s garbage somewhere.

"Where did you get such a strange battery?"

"Don't ask where it came from."

"If I have time later, record its usage data."

"Maybe I can still use it."

Wang Fan said with a smile, using Tao Weihui as a tool.

"Will this work?"

"Don't connect it to the power supply. It will be embarrassing if it can't even move the propeller of the plane."

"I might as well not save the 100 yuan and buy a new one."

Tao Wei was a little doubtful.

Wang Fan patted Tao Wei on the shoulder: "Believe me, it will surprise you. Remember, record the usage data."

Listening to Wang Fan's words, Tao Wei took the battery back that night, plugged it into his small plane, and started doing experiments.

What he never expected was that,

From the time we boarded the plane at eight o'clock until eight thirty.

The performance of the aircraft is still fully loaded.

"Awesome, Brother Fan."

"Where did you make the battery? If the energy density is calculated based on unit volume, it has almost caught up with the domestic first-class level."

After testing for a while,

Tao Wei took out his cell phone and made a call.

Wang Fan: “How is the data?”

"It's been testing for half an hour, and it's still in full performance."

“The condition has never been better.”

Tao Wei replied immediately.

"ok!"

"Remember to send me the data before the end of the night."

"You can continue to do it." Wang Fan was not surprised at all by this result. Judging from the actual performance, it only took half an hour to get anything.

"Can we continue to do this?"

When Tao Wei heard this, he was even more surprised. Then he took a private look and found that no one was there. He lowered his voice and asked secretly:

"Did you get it from the scientific research results of one of the teachers in the research group?"

"Don't let such excellent data be discovered by then."

"We both have to suffer!"

Wang Fan smiled and said with certainty: "Don't worry, nothing will happen."

“Use it with confidence!”

"I'll tell you if anything happens."

The voice fell,

After being given a shot of cardiotonic, Tao Wei had nothing to worry about.

Listening to Wang Fan's affirmative tone,

He even wanted to play something big.

"Brother Wang, lend me your data port."

"what?"
