In recent years, with the development of science and technology, drone has expanded from the military field to the civil field, it is widely used in the fields like agriculture, forestry, electricity, security, etc. As the application range of drones is increasingly wide, there are also a wide variety of drones in the market, but all these drones share one obvious problem - the limited endurance, and the main factor that affects the endurance is the diy drone battery
. The endurance of drones is the weakness that restricts the development of drone industry, and it is also a technical problem to be tackled urgently in the development of drones in the world. At present, there are several ways to solve the problem of drone endurance.
1. Fuel Cell
The multi axis drone HYCOPTER, which uses hydrogen fuel cells, can fly for 4 hours without any load, it can still fly for 150 minutes even if with a full load of 1Kg, which is much longer than the time of endurance of the drone powered by a lithium battery.
In 2010, the UK's ultra light solar powered drone, “He Feng”, that were installed solar panels and ground based laser power to improve the flight time created a new drone flight time record of 14 days of continuous flight.
3. Innovation of Lithium Battery
In September 2015, as a leader in the field of electric vehicles, the United States launched a prototype of a drone that is specially designed for aerial applications. American companies obviously have more experience in charging batteries. It is reported that the drone carries a 10000mAh battery, a single charge can support a 60 minute flight, the charging time is about 20 minutes.
