I failed a course, and the system became my study supervisor.

Chapter 58 ABS Battery System
But Xu Ling changed his mind and decided that if he wanted to put this battery system into practical use, it would definitely be helpful to have a paper in hand.

On the one hand, publishing in a more influential journal would allow Xu Ling's ideas to be more widely disseminated, potentially attracting the attention of a group's CEO. On the other hand, publication would provide the feasibility of the approach with both recognition and authority.

As for starting his own company with his assets, Xu Ling's vision is not that far-sighted.

So, start writing now!
Without delay, Xu Ling's hands began to tap on the keyboard, and the title of a paper came into being:

ABS Optimization of UAV Flight Life

The so-called "ABS" is the name given to this battery system by Xu Ling himself.

"A" is the first letter of the English word "Add". Xu Ling wanted to express the meaning of fusion and combination, but his English vocabulary was not sufficient and he could not think of words like "merge".

As for the "B" and "S" at the end, they are easy to understand, which are the first letters of the words for battery and system respectively.

Abstract: Drone battery life has always been an important part of drone performance. This paper will discuss a battery system management method that uses existing battery technology to optimize battery life.

Of course, words alone are not enough. Xu Ling understood that his description of the system alone was far from enough, even if the theoretical analysis was rigorous enough. Readers could easily dismiss it as a fantasy rather than a conjecture.

To this end, Xu Ling still needs to conduct relevant experiments to verify that the theory is indeed feasible.

Of course, this experiment can only be a simulation using software such as Matlab. Xu Ling does not have the conditions to actually operate it.

But this problem is very complex, and modeling is not that easy. Xu Ling did not rush it, but simply added this task to his daily routine.

It will be published when it is finished.

I used the battery system problem to avoid reviewing modern history, but the exam was unavoidable.

"Please take out your campus card for inspection. Please also make sure you don't bring any electronic devices with you. You don't need pen and paper for the computer-based exam. It's best if you only have your campus card in front of you."

Xu Ling's history teacher, whom he had barely seen all semester, looked very serious and emphasized the exam discipline in a very strict manner.

Is it really that important? I've never seen a teacher check the campus card before so many exams.

Xu Ling curled his lips.

However, as soon as the exam started, Xu Ling was dumbfounded.

Of the first ten multiple-choice questions, Xu Ling was sure he could answer only one.

No? If you don't test the main events, and only focus on the minor details, what's the point?

The tables in the computer room all had partitions, so when Xu Ling turned his head, he could only see the shiny top of the head of the classmate next to him.

Is this life?
Xu Ling filled in the answers he was not sure about at all with a wry smile, looking sad.

Xu Ling also complained bitterly about the afternoon exam, racking his brains but unable to produce much. Looking at the overflowing papers handed in by other students, Xu Ling's eyes were filled with envy and jealousy.

I shouldn't fail the general education course, right?
This was the only thought in Xu Ling's mind.

Regardless of the outcome, modern history has come to an end, and Xu Ling's focus has returned to physical experiments.

After a few days, Liang Xiuyuan and Huang Yunfeng finished writing the experimental report on juicy solar cells.

Their writing was very interesting, detailing the group's exploration process, including how to resolve unstable voltage and low photoelectric conversion efficiency. It was like writing a narrative essay, and you could even see the language description.

This was quite unusual. Xu Ling was just a little amused and didn't say anything about rewriting it, because the entire experimental report would not be presented when making the report.

"So what experiment shall we do next?"

Qin Qin asked naturally.

The other members of the group also turned their attention to Xu Ling.

"Well, there's not much time left. I roughly calculated that it should only be enough for us to complete one experiment."

Xu Ling pondered for a moment and spoke slowly.

For a moment, the atmosphere grew tense. With only one question to choose from, one had to be extremely cautious.

Ji Yun asked solemnly, "Then how should we choose?"

Xu Ling had a single idea for choosing the topic: pick the one most likely to be chosen.

After hearing what Xu Ling said, the few people did not find their doubts resolved, but became even more confused.

Xu Ling had no choice but to explain: "It's the same idea as when I first chose the topic. I considered the difficulty of experimental operation, the difficulty of experimental optimization, the difficulty of theoretical analysis, and the theoretical value."

Everyone finally reacted and started discussing it.

"Let's go with magnetic levitation. It seems a group has done it before, so we can gain some experience."

Huang Yunfeng muttered.

"Then why don't we just go and get the scriptures first, and then do another experiment?"

Liang Xiuyuan answered without thinking.

"Where's the howling board?"

"."

After half an hour of discussion, Xu Ling finally came to the final conclusion - the problem of shooting rubber bands!

The background of the problem is this: if a rubber band is unevenly stretched when shot, causing it to rotate, it can fly farther. The question requires exploring the underlying principle and the maximum distance under different conditions.

This problem can be said to be completely within Xu Ling's comfort zone, because the aerodynamics it involves are something Xu Ling is relatively familiar with.

As a result, the entire experiment, both theoretical analysis and specific experiments, went smoothly.

The only problems the team encountered were with the rubber bands rather than the experiment itself.

Since ordinary rubber bands are made of very cheap materials and are not strictly controlled for quality, the fluctuation in the quality of each rubber band is unknown, and the impact it causes cannot be ignored like that of ping-pong balls.

To this end, Xu Ling specially purchased rubber bands that were slightly more expensive, and paid great attention to the "fatigue" of each rubber band. Basically, each rubber band only flew once, which controlled the uncertainty below 5%.

Time passed quietly as Xu Ling made intensive preparations.

Finally, on June 10th, the provincial competition finally opened. The schedule was very tight and the final qualifying teams were decided in a few days.

Xu Ling's group and the first group both advanced to the national competition, and the remaining qualifying spot went to Shanghai University of Science and Technology.

Zeng Boyuan and Liu Chunlin, the team leaders, were very pleased. They did not expect that the two groups would actually meet the initial expectations given to them.

As for the teams that failed to advance, it’s not that they are weak, but they were just not as well prepared as Xu Ling and his team.

"Not bad, Xu Ling. Let's meet in the finals then?"

Yu Wenkai said to Xu Ling with some excitement.

"it is good!"

Xu Ling nodded heavily.

"We'll see!"

"come on!"

The two encouraged each other.

National competition?
Xu Ling is determined to win!
