What is the impact of long coldness on agriculture spraying UAV batteries and how to deal with it?

Drone technology is constantly evolving with time. In ancient times, the drone was only used for search and rescue, but now the uses of the drone are constantly expanding. Drones are used to deliver items, firefighting, videography, and more. On top of all, they are used in the agriculture sector. Drones are commonly used for spraying in agriculture. But they are also used as seeds and feeds in the agriculture field.

We know you are tense about the drone battery performance in prolonged, cold weather. Yes, you are right, cold batteries drastically impact UAV batteries. But what are they, and how would you deal with them?

If you wish to know the answer to these common questions, you must read this article. This article will give in-depth information about the low-temperature impact on drone batteries and how to cope with this impact. This article will also give other helpful information about drone spraying technology.

What are the advantages of drone spraying in agriculture?

Drones are powerful tools for farmers and agronomists because they can inform them about the health of their crops. Besides, drone spraying holds several more benefits, increasing their demand in agriculture. Below are the top advantages of using drone spraying in agriculture-

1. Increased Efficiency

The first advantage of using drone spraying in agriculture is that it can increase your efficiency. They can quickly cover a large land area, making it easier and quicker for farmers to monitor and manage their crops. Drones can fly over areas difficult for a human to access, like flooded fields or steep slopes.

2. Provide Better Data and Cost Savings. 

Before drone technology, farmers relied on satellite imagery to get insight. But the problem in this image was they could typically zoom in so far, and it could take a few weeks to get the images. The drone can provide high-quality images in less time. They could offer more insight compared to satellite images. Farmers and ranchers can better utilise data provided by drones to picture crop growth, health, and soil moisture, allowing them to make better decisions.  Flying drones multiple times on a field is comparatively cheaper than satellite imagery.

3. Reduced Environment Impact

Spraying drones can also reduce the environmental impact by reducing the number of chemicals released into the environment through traditional spraying. It can also decrease the risks of pollution and environmental damage.

Farmers can apply inputs more precisely and in smaller quantities with drones, decreasing the total amount of chemicals used. This can assist in protecting soil health, reduce water pollution risk, and reduce the impact on nearby ecosystems.

What are the challenges of using drones in agriculture?

Indeed, using drones in the agriculture sector holds several advantages. But you might face a few challenges while using these drones. Below are the top challenges of using a drone in agriculture:

1. Regulatory  Barrier 

Several countries like India have put regulatory barriers on the use of drones. Farmers might have to take permission for the use of drones. This makes it challenging to use this technology.

2. Lack of Knowledge

Most farmers are comparatively less literate than those working in other professions. They did not do the same trick of using drones in their field because they needed proper knowledge and training to use them. This can make it challenging for farmers to adopt this technology because they need more confidence in using these drones.

3. Cost 

Drones come with high prices that people with less earnings cannot afford. Most farmers need more financial assets to invest in drones. The high price of these drones is still stopping farmers from using this technology.

What batteries are used in agricultural drones?

Agriculture drones commonly use rechargeable lithium-ion batteries. This battery is also called a plant protection battery. Both high and low temperatures affect these types of batteries. Apart from lithium-ion batteries, drones are also equipped with lithium polymer batteries, which have a variety of benefits, like lightweight, compact, high energy density, and more.

What is the impact of long coldness on Agriculture Spraying UAVs Batteries?

As mentioned earlier, most drones are equipped with high-rate lithium-ion batteries. The direct effect of low temperature on this battery is that the discharge performance of this battery will simply be decayed.

This happens because low temperature reduces the lithium-ion activity inside the battery. It also slows down the overall chemical reaction inside the battery, which results in a slower power conversion rate. The low temperature also reflects the charging energy storage.

Remember, electrodes and electrolytes are the heart of every battery. If the temperature becomes low, the electrode's reaction rates will also drop with the temperature. Moreover, the battery power input also decreases as the temperature goes down. While lithium-ion diffusion in the carbon cathode slows as the temperature drops, lithium precipitation is also more accessible in cold weather.

You'll be surprised to learn that standard lithium-ion batteries are unable to charge below 0 degrees C. Usually, it shows regular charging, and there will be precipitation of the lithium metal on the surface of the metal. If frequent low-temperature charging harms batteries and reduces battery safety, metallic lithium develops and deposits more while charging. This can degrade battery life and potentially cause short circuits.

How to deal with General Agriculture Spraying UAVs Batteries in long cold winter

After reading about the overall impact of low temperatures on the drone battery, you might be afraid. But the best part is that you can reduce these impacts by following the steps below-

●While keeping the plant protection drone batteries in a subzero low-temperature condition for an extended period of time, it is strongly recommended that they be stored in a tightly sealed explosion-proof box with a temperature environment of 10 °C 25 °C.

●You must avoid charging directly in the cold weather. You can use physical heating or wait until the temperature goes above 10’C.

●You must take these batteries lightly and avoid corrosion and extrusion. If you do not do that, it will significantly damage the internal battery cell.

Conclusion 

Drones can provide significant benefits to the farmers and agriculture sector. But low–temperatures can have a significant impact on drone batteries. If you want to protect your battery from these impacts, you must use these drones when temperatures become under control.
