The public account has been in operation for some time, but it has been intermittently updated. Some time ago, I asked a special person to be responsible for the public number. I finally got the original invitation. I applied for the original copy today, and I sent a dry message to the audience.
The application of drones in the power industry is nothing more than two types, one is the line of inspection and the other is the line. Due to many factors, the patrol line has not yet become a mainstream patrol tool, but it is speculated that it will become the mainstream soon. Today's protagonist is the power line drone. I believe that many of the officials will also use the keyword Baidu, but the original article can only be found in the official website of the electric drone I did, not to mention WeChat. What are the prospects, uses, and how to save money for the drones? These are not listed. I believe that most of the officers who can enter this public number have a lot of understanding of the unmanned rack lines.
What should I say?
After thinking about it, I started with some small functions or some small accessories of the drone. I have time to update it. I don't have time to wait, haha, I will try my best to update it.
Today, I will talk about the battery of the lined drone. Is the parallel scheme reliable?
First explain the battery parallel solution, see the picture:

Well, the problem is coming, "Teacher, I didn't learn high school physics." It doesn't matter, look at the picture below:

Understand it, that is, two batteries, through the internal or external parallel circuit, to increase the battery capacity.
Our theme today is that the parallel operation of the lithium battery using the lithium battery is not reliable. Let us first understand the advantages and disadvantages of the parallel solution.
Advantage 1: Quickly expand the battery power in a short time and complete the flight at a longer distance.
Advantage 2: A single battery fails, and another battery supports the drone to return.
Advantage 3: Low-capacity battery has low cost.
Look at the shortcomings again:
Disadvantage 1: The flight efficiency is low, and the battery also has weight. Although the capacity is the same as that of the large battery, the weight is heavier and the battery life is reduced.
Disadvantage 2: The voltage between the parallel batteries is inconsistent, which will cause current backflow. The flight control is affected by the current instability and shut down. Oh, the aircraft is fried.
Three advantages, two disadvantages, seemingly parallel and reliable!
Today is the analysis of the wired application. Is this actually the case?
Come, let's analyze its advantages first:
Advantages analysis: For the products developed by regular manufacturers, there must be performance tests, a corresponding matching large-capacity battery, no problem flying more than 1 km, it is said that I can fly up to 3km in parallel. Actually? Certainly it will not increase linearly, and it will be almost the same for a few hundred meters. The 1000m application is sufficient for most construction requirements, and it is very stable, so increasing the distance in parallel, the advantage is not big, can be ignored.
Advantage 2 Analysis: A single battery fails, and another battery supports the drone to return. A battery is broken, and all the power of the drone is instantaneously handed over to another battery load. It is really a problem that the aircraft can get back. So the advantage does not exist.
Advantage three analysis: low-capacity battery cost is low. I bought tens of thousands of things and still care about these hundreds of pieces?
Let's look at the disadvantages again:
Disadvantage one analysis: low efficiency. Originally, two batteries can fly for one hour and only fly for 35 minutes in parallel. This efficiency is really low.
The second shortcoming analysis: This shortcoming will be the most deadly shortcoming. The lithium battery industry standard has just come out. At present, the lithium-ion battery supplier in the market is profitable. If you want to know that the best lithium battery manufacturers in China are not willing to do parallel schemes easily, Because the consistency requirements of the parallel cells are very high, the cells are inconsistent. As the usage time increases, the voltage loss of each cell will be inconsistent. The catastrophic consequence is that the drone is controlled to shut down and the aircraft is fried. Lithium battery assembly technology is still very simple, so some drone manufacturers buy their own cell assembly in order to pursue profits, and this battery can not be used in parallel.
Having said that, parallel PK parallel connection is not reliable, who won? I believe you should have an answer.
Nani, are you looking at the conclusion? Ok, my conclusion is:
The parallel scheme of the lithium battery of the drone is theoretically a more reliable and safer solution, but the consistency requirement for the battery core is relatively high. At present, the batteries used by most people cannot meet this standard. It has become a gimmick, a potential security risk. So, the lithium battery of the drone is not reliable, or the old and practical large-capacity battery.
