Meaning
The endurance battery for unmanned aerial vehicles refers to a specialized power lithium battery designed specifically for drones, with higher energy density, more stable discharge performance, and significantly longer single flight time than ordinary batteries.
It is mainly used to extend the hovering, cruising, and operation time of drones, meeting the needs of long-term operations such as aerial photography, inspection, surveying, logistics, and plant protection. It is commonly seen in industrial and industry level drones.
Basic principles
- At present, the mainstream endurance batteries for unmanned aerial vehicles are mainly high rate lithium polymer batteries (LiPo) and lithium-ion batteries (Li ion), while some high-end models use solid-state batteries and hydrogen fuel cells.
- Charging and discharging are achieved by inserting and removing lithium ions between the positive and negative electrodes of the battery;
- Using high-capacity battery cells and optimized packaging structure to store more electrical energy within limited weight and volume;
- Cooperate with the Battery Management System (BMS) to monitor voltage, current, and temperature in real-time, ensure stable discharge of high current, prevent overcharging, overdischarging, and overheating, and provide continuous power supply for the drone motor, flight control, and gimbal.
Characteristics
High energy density
Under the same weight and volume, it has a larger capacity than ordinary aerial photography batteries, which can significantly increase flight time.
Good high rate discharge performance
It can support high current requirements during drone takeoff, acceleration, and hovering, with stable power output.
Longer cycle life
Supports more charging and discharging cycles, with slower attenuation, suitable for high-frequency industrial operations.
Stronger stability and security
Built in comprehensive BMS protection, with overvoltage, overcurrent, overtemperature, and short-circuit protection, better adaptability to high and low temperature environments.
Better weight control
While increasing capacity, try to control the weight as much as possible to avoid offsetting the battery life advantage due to excessive weight.
Support fast charging or intelligent battery swapping
Some long-range batteries support fast charging and hot swapping, enabling continuous and uninterrupted operation.
Scope of application
■ Aerial photography and film and television shooting
Long term aerial surveys, large-scale aerial photography of scenery, and filming of movies and TV dramas to reduce frequent takeoffs and battery swapping.
■ Inspection of electricity, pipelines, and bridges
Long distance route inspection, mountainous area inspection, covering longer routes with one takeoff.
■ Agricultural crop protection drone
Spraying operations on large areas of farmland can reduce the number of back and forth battery exchanges and improve operational efficiency.
■ Surveying and Geographic Information Collection
Large scale terrain mapping and 3D modeling, with a larger coverage area for a single flight route.
■ Security and Patrol
Long term patrol and monitoring of parks, borders, rivers, and forests.
■ Logistics and delivery drones
Long distance material transportation, delivery to remote areas, and improving one-way flight radius.
■ Emergency rescue and search and rescue
Forest search and rescue, disaster investigation, extending aerial search time, and improving the success rate of search and rescue.
