Daily maintenance and emergency response of drone batteries

A drone is a type of drone composed of flight platforms, navigation and flight control. With the help of ground remote control or navigation and flight control, it can achieve various operations, aerial surveys, inspections, monitoring, and assistance in agriculture. Compared to traditional operation methods, using drones for operations has advantages such as high accuracy, good maneuverability, low cost, high safety, and high efficiency. However, it is well known that in order for drones to complete efficient work tasks, they need lithium polymer batteries with multiple obvious advantages such as high energy density, miniaturization, ultra-thinness, lightweight, high safety, and low cost to provide power sources, From this, it can be seen that the importance of drone battery modules to drones is self-evident. Therefore, it is very important to carry out daily maintenance of drone batteries and correct handling in case of emergencies.

The general maintenance method is to regularly inspect the battery body, handles, wires, and power plugs, and check the appearance for damage. Deformation, corrosion, discoloration, peeling, and whether the plug between the plug and the aircraft is too loose. After each operation, the appearance of the battery and the power plug must be wiped with a dry cloth to ensure that there are no impurities such as dust left and to avoid battery corrosion. After flight, the battery temperature is too high, and it needs to be charged after the battery temperature drops below 40 ℃ (the optimal temperature range for battery charging is 5 ℃~40 ℃). Charging the battery after the external temperature drops can greatly improve its service life. The temperature is relatively high in summer, it is best not to expose the battery to sunlight. After discharging the battery in winter, useful insulation methods (such as using an insulation box) should be used to ensure that the battery temperature is maintained above 5 ℃, and the battery life is significantly shortened in low temperature environments.

Drone batteries may encounter different emergency situations during use. For example, when the battery catches fire during the charging process, first cut off the equipment power, use asbestos gloves or clips to remove the burned battery, place it on the ground or in a fire sand bucket, cover the burned lithium battery with asbestos blanket, and use fire sand to cover the asbestos blanket to block air and suffocate it. If it is necessary to discard the depleted battery, please thoroughly immerse the drone battery in salt water for more than 72 hours to ensure complete discharge, and then dry it before scrapping. Using carbon dioxide to extinguish the fire will not pollute the environment or corrode the machine, but can only achieve an instant suppression effect on the flames. It needs to be used together with sand and asbestos blankets to block suffocation, which is the best way to handle lithium battery incineration. Drones are generally expensive. If a fire is found, other personnel should be immediately notified for support to minimize property damage and personal injury.

The above is an introduction to the daily maintenance and emergency response methods of drone batteries. Mastering the knowledge of daily maintenance and emergency response methods of drone batteries is a necessary lesson for every drone operator. It can greatly improve the cycling life of drone batteries, enable drones to better play their role, reduce operation and maintenance costs, and increase profits.
