Longer flight times and longer battery lives are increasingly necessary as drone technology keeps gaining ground in commerce and enterprise, writes Dr. Shaun Passley, CEO and Founder of Zenadrone
Drones, also commonly known as unmanned aerial vehicles (UAVs), have gained popularity in recent years as a result of their practicality, accessibility, adaptability and cost-effectiveness. Their versatility means they can be applied across industries like agriculture, construction and logistics, but as their popularity grows, so too does the need for more dependable and effective solutions.
A thorough understanding of drone battery technology can aid in lowering maintenance costs, extending the duration of the flight, and expanding a drone-based business’s offerings in other capacities. The most popular drone batteries are lithium-polymer and lithium-ion, which are perfect for drone applications since they are portable, have a high energy density and can be recharged.
Performance factors
Unlocking the full potential of a UAV requires a thorough understanding of its batteries. Different drone models and applications require different power sources, which come in a variety of sizes, shapes, and capacities. Battery life can be impacted by a number of variables, including battery state, weather, flying speed, payload weight, and more.
Design
Weight, energy density, and heat dissipation are just a few variables that affect how well a battery performs. For instance, a UAV’s potential to rise off the ground to a certain height requires more energy the heavier it is, which in turn reduces flying time. As such, the capacity and flight time of drone batteries is largely dependent on their weight.
Capacity
Battery capacity is the maximum amount of energy that a battery can hold, whereas lift capability refers to a drone’s ability to reach and maintain a specific altitude while carrying cargo. A larger battery offers the drone more power, increasing its lift capacity and extending its flying time, meaning as the battery capacity of a drone increases, so too does its lift capacity.
Flight Time
The altitudes that a drone is capable of reaching, how long it can stay in the air, and the size and weight of payloads it can carry are all influenced by its battery capacity and lift capability. A battery can store more energy when it has a higher energy density, which extends flying times. A crucial element is also heat dissipation; a battery discharges rapidly when it warms up, which in turn cuts the flying time.
Tips for extending battery life
Given the factors involved in drone battery design, it is vital to maintain and prioritise battery life.
Staying cool is one of the easiest ways to extend the life of a drone battery. Out of direct sunlight and away from moisture will certainly have a beneficial effect
Overcharging can lead to overheating and a reduced lifespan, so they should never be left connected for longer than necessary
Battery management software can be a wise investment for larger drones in a professional setting; this software can provide actionable insights based on usage and performance, enabling users to further expand their capacity or replace them before they start underperforming
How battery capacity and lift capability relate to one another
Lift capability and battery capacity are correlated. A drone is given more lift by a battery the more potent it is. As previously stated, a larger battery may shorten the flight time, despite increased capacity. Therefore, operators must strike a balance between the desire for longer flight times and the requirement for a higher lift. Larger batteries might be needed for a drone with a heavier payload, but this will reduce the flight time. This delicate balancing act highlights the importance of careful drone battery management and design.
How to lessen the effects of batteries on the environment, particularly lithium mining
Mining resources like lithium and other environmental impacts of drone battery production are also relevant. Lithium mining has, in certain instances, resulted in the eviction of local residents and can pollute the soil and water. Companies may be considering cooperating with vendors who prioritise sustainable sourcing or using recycled products to alleviate these problems and lessen their negative effects on the environment. Battery recycling or safe disposal can also assist lessen the impact on the environment.
Conclusion
Battery technology is essential to the future success of drone-based businesses at a time when the sector is growing. The flight time of drones is affected by the battery capacity, design, and lift capability, and balancing these aspects is essential for an operator to be successful. Some of the environmental effects of manufacturing and disposing of batteries can be reduced by preserving battery life and practising safe disposal. In years to come, drone activity will be second nature in professional domestic environments, and advancements in battery technology will remain essential for enabling new and creative applications for the technology.
To maximise the range, performance, safety, and efficiency of drone batteries, it is essential to understand the factors that must be taken into account while developing and operating drone batteries. For a firm in any industry to fully utilise UAVs and spur growth in other sectors, adopting sustainable battery technology and putting into practice good drone battery management techniques are crucial.
