6 consejos para proteger drones UAV Baterías de litio

junio 23, 2020

Tanto las baterías de UAV como las baterías de teléfonos celulares son baterías de litio, que son la fuente de energía del equipo y requieren un mayor rendimiento de seguridad. Pero hay una diferencia entre los dos, La relación entre la batería del UAV y la batería del teléfono móvil tiene una característica importante: descarga, La batería del UAV debe descargarse, so as to meet the requirements of UAV use in different environments, such as aerial photography, if encountered a strong wind, then the need battery can achieve high current discharge to make corresponding compensation, to ensure the position of the UAV. Because of the different use requirements, the life of UAV battery is relatively short.

6 consejos para proteger drones UAV Baterías de litio:

Do not over discharge

The discharge curve of the battery shows that when the discharge starts, the voltage drops faster, but the discharge is between 3.9~3.7 V, and the voltage drops less quickly. But once dropped to 3.7 V, the speed of voltage drop will be accelerated, poor control will lead to overplay, light damage battery, heavy voltage is too low to cause explosion machine. Some mold friends because the battery is less, so each time will overplay, such a battery is very short life. The strategy is to fly as little as one minute as possible, to fly a cycle more life, would rather buy two more batteries, not each time to fly the battery beyond the capacity limit. To make full use of the battery alarm, an alarm should land as soon as possible.

Do not over charge

1. use a dedicated charger. this charger can be lithium ion or lithium polymerization special charger, both are very close. Some mobile phone chargers can be used to charge lithium polymer batteries. This will not damage the battery.

2. accurately set the number of cell monomers in the battery pack. For the first few minutes of charging, you must carefully observe the charger’s display screen, which will show the number of batteries in the battery pack. If you are not clear, you should not charge or use a charger that you are familiar with.

3. charge a new lithium battery group for the first time, check the voltage of each cell unit in the battery pack, and the same should be done every 10 charge and discharge later. This is absolutely necessary, and a battery pack with an unbalanced voltage will still burst when the number of cells is selected to charge correctly. If the cell cell voltage varies by more than 0.1 volts, you should charge each cell voltage to 4.2 volts to make it equal. If the battery cell voltage difference after each discharge is more than 0.1 volts, it means that your battery has failed and should be replaced.

4. don’t charge without care

5. use a safe position to place the charged battery and charger.

6. generally do not have a manufacturer’s special instructions, charging current should not exceed 1 do. Batteries that now support high current discharges also support more than 1 C of current charging. But it will greatly shorten the life of the battery, buy 3 batteries to charge alternately than buy a battery and have to charge quickly is more cost-effective.

Do not store the battery with full charge

Full battery, can not be fully stored for more than 3 dias, if more than a week does not release, some batteries will be directly bulging, some batteries may not drum for the time being, but after several full storage, the battery may be directly scrapped. Por lo tanto, the correct way is to recharge after receiving the mission, if there is no mission within 3 days after the battery is used, please charge the monolithic voltage to 3.80~3.90 V save. The battery should be discharged to 3.80~3.90 V within 3 days after charging. If the battery is not used within three months, keep the battery after charging and discharging once, que puede prolongar la vida útil de la batería. El almacenamiento de la batería debe colocarse en un lugar fresco., almacenamiento a largo plazo de baterías, lo mejor es colocarlo en una bolsa sellada o en una caja de explosión sellada, temperatura ambiente recomendada de 10 ~ 25 grados, y seco, gas no corrosivo.

cuatro、 Embalaje no dañino

El embalaje exterior de la batería es una estructura importante para evitar la explosión de la batería y el fuego de las fugas.. La rotura de la película plástica de aluminio de la batería de polímero de litio conducirá directamente al fuego o explosión de la batería.. La batería debe ser ligera, sostenga la luz, en el avión para arreglar la batería, banda de lazo para estar apretado. Porque es posible hacer un gran vuelo dinámico o dejar caer la máquina, la batería porque la banda no está apretada y tirar, que puede dañar fácilmente la piel externa de la batería.

Fives、 Sin cortocircuito

This often occurs during battery welding line maintenance and transportation. A short circuit can cause a battery to fire or explode. When it is found that the battery has broken after a period of time, it is necessary to reweld the wire, especially pay attention to the electric iron do not contact the positive and negative electrodes of the battery at the same time. Adicionalmente, the best way to transport the battery is that each battery is individually wrapped in a self-sealing bag and placed in an explosion-proof box, so as to prevent short-circuiting of the positive and negative electrodes of a piece of battery simultaneously touching other conductive substances during transportation due to bumps and collisions.

No hypothermia

This principle, many flying friends will ignore. Low-temperature weather often occurs in the north or in high-altitude areas, when the battery is placed outside for a long time, its discharge performance will be greatly reduced, if you have to fly at normal temperature when the flight time, sin duda será un problema. En este punto, el voltaje de la alarma debe elevarse (como un voltaje de alarma único para 3.8 V), porque en el ambiente de baja temperatura la caída de voltaje será muy rápida, alarma de aterrizaje inmediato. La batería debe mantenerse en un ambiente cálido antes del despegue, como dentro de la casa, coche, incubadora, etc.. Para despegar instale rápidamente la batería y realice la misión. Acorte el tiempo a la mitad de la temperatura normal durante el vuelo a baja temperatura para garantizar un vuelo seguro.
