Agricultural Drone Battery Common Problems ＆ Solutions

During the operation and maintenance of planting agri UAV drones, the intelligent flight drone battery as a key component, its performance and stability are directly related to operational efficiency and flight safety.The following are more common plant protection drone battery faults and their countermeasures:

Drone Battery Discharged or Slow Charging

Failure phenomenon:

After the drone battery is connected to the charger, the charger does not respond or the charging progress is slow.

The time required for the intelli8gent drone battery to be fully charged is much longer than normal.

Solution:

● Check the Charger and Battery Interface: make sure that the charger and intelligent flight battery interface are connected tightly without looseness or oxidation.

● Replace the Charger: try charging with another charger of the same model to troubleshoot the charger.

● Check the Internal Battery: If there is a short circuit or damage inside the battery, you need to contact a professional maintenance personnel for overhaul or replacement.

● Adjust the Charging Environment: Ensure that the charging environment is at a suitable temperature to avoid too high or too low a temperature affecting charging efficiency.

UAV Battery Discharge too Fast

Trouble phenomenon:

Intelligent drone battery in the normal use of the process, the rapid decline in power, can not meet the operational requirements.

The battery discharge curve is abnormal, and the phenomenon of sudden power loss occurs.

Solution: 

● Check the UAV Battery Health Status: use professional equipment to detect the battery health status, if the battery aging is serious, need to replace the new battery.

● Optimise Flight Parameters: adjust the flight parameters of the plant protection UAV, such as lowering the flight speed, reducing the load, etc., in order to reduce the battery discharge rate.

● Avoid High-temperature Operation: operating in a high-temperature environment will accelerate the discharge of the high power UAV battery, and the UAV battery should be used in the appropriate temperature range as much as possible.

● Regular Maintenance of the Battery: Charge and discharge the UAV battery regularly to maintain the battery activity.

Intelligent Flight Battery Expansion or Leakage

Trouble Phenomenon:

The intelligent flight battery case is swollen and deformed, or the electrolyte leakage phenomenon.

Solution:

● Discontinue Use Immediately: when the intelligent flight battery is found to be swollen or leaking, stop using it immediately and keep it away from fire sources and flammable objects.

● Isolation: Place the faulty intelligent flight battery in a safe area and avoid contact with other batteries or electronic devices.

● Contact Professional Repair: Send the faulty intelligent flight battery to a professional repair organisation for treatment, avoid disassembling it by yourself and causing danger.

● Analyse the Cause: Analyse the cause of intelligent flight battery expansion or leakage, such as excessive pressure inside the battery, changes in the composition of the electrolyte, etc., so that preventive measures can be taken in subsequent use.

Drone Battery Fails to Start the Drone

Failure Performance:

After the agri drone battery is installed in the drone, the drone fails to start or maintain flight.

Solution:

● Check the Agri Drone Battery Connection: make sure that the battery is tightly connected to the drone, with no loose or poor contact.

● Check the Battery Level: make sure the agri drone battery is fully charged to avoid the drone failing to start due to low battery level.

● Check the Drone Power System: check whether the drone power system is working properly, such as power module, power line, etc.

● Reset the UAV System: try to reset the UAV system to the initial state and re-perform the flight test.

Drone Battery Memory Effect

Failure Performance:

Drone battery memory effect such as battery capacity decreasing, charging time getting longer, etc. occurs after several times of partial charging and partial discharging.

Solution:

● Periodic Deep Discharge: periodically deep discharge the UAV drone battery to nearly 0% charge and then fully charge it to eliminate the memory effect.

● Avoid Frequent Fast Charging: reduce the number of times you use fast charging and try to use slow charging to prolong the UAV drone battery life.

● Maintain Battery Activity: Regularly maintain the UAV drone battery by charging and discharging to keep the battery active.

● Use Smart Charger: Use a charger with smart charging function to better manage the battery charging process.

Shortened Drone Battery Life

Trouble Manifestation: 

Drone battery life is significantly shortened after a period of time, and it is not able to sustain a long flight even when fully charged.

Solution: 

● Avoid Deep Discharging and Overcharging: minimise the number of deep discharging and overcharging of the battery to prolong the drone battery life.

● Optimise Flight Strategies: adopt more energy-efficient flight strategies, such as lowering flight speeds, reducing loads, etc., to reduce the drone battery discharge rate.

● Regularly Check the Battery Health Status: Use professional equipment to regularly check the battery health status, and find and replace the aged drone battery in time.

Choose High-quality Drone Batteries: when purchasing batteries, choose high-quality, high-performance battery products to improve battery life and safety.

Conclusion

the common failures of plant protection drone batteries include abnormal charging indicator, expansion or leakage, overheating, inability to start the drone, memory effect, and shortened life span. In response to these failures, we can take measures such as checking the charger and battery connections, isolating and treating the faulty battery, optimising the conditions of use, resetting the UAV system, discharging the battery deeply on a regular basis, and checking the battery's health status to cope with them. At the same time, strengthening the daily maintenance and care of batteries and raising awareness of the safety of battery use are also important measures to prevent battery failures.
