Why can't the drone battery last more than 30 minutes

Introduction: Now the battery technology is so developed, but the general flight time of drones is 10-30 minutes. At this time, someone asked why the battery of the drone cannot exceed 30 minutes? Is it really?




With the development of science and technology, UAVs have expanded from the military field to the civilian field, especially in the fields of agriculture, forestry, electricity, security, etc. that are widely used in the civilian field. At present, the drones on the market mainly use lithium polymer batteries as the main power, and the endurance is generally between 10 minutes and 30 minutes. At this time, some people will ask why the drone battery cannot exceed 30 minutes? Because according to modern battery technology, it is possible to exceed 30 minutes.




The question should be why the battery of ordinary civilian drones or consumer drones cannot exceed 30 minutes, because military drones and drones researched by some countries do not have this limit. What the editor wants to say here is that if the limit is 30 minutes, can mavic2 dare to mark the maximum flight time (windless environment) of 31 minutes? In addition, there is a domestic fixed-wing continuous flight time of 45 minutes, which is also sold in China. So this has little to do with the policy, but why is the general drone flight time of 10 to 30 minutes?




The editor here thinks that there are two reasons why the drone battery cannot exceed 30 minutes.

cost




UAVs still have a certain technical content, and the price is relatively high. The general public is reluctant to buy them. In order to control the price within a certain range acceptable to the public, it is necessary to control the cost. The performance of the aircraft cannot be lost, so what can be reduced to reduce the cost price? Yes, the battery cost. But a drone can't fly for a few minutes without power, right? If no one buys it, then it will be fine if it takes 10 minutes, and the general public will enjoy flying for 10 minutes or so. Even better... just give the money.




Image transmission and remote sensing technology




Another possible point is image transmission and remote sensing technology. Civil and consumer image transmission and remote sensing technology are not so developed, so I think the time limit of aircraft flight is probably due to image transmission and remote sensing technology, not battery technology.




For example, if the farthest image transmission and remote sensing technology is 10 kilometers, then the screen will be cut off when the flight reaches 10 kilometers. At this time, the aircraft needs to automatically return. What if the plane loses power during this period? So I think this battery time is the maximum time from the starting point to the farthest distance and then back to the starting point from the farthest distance (based on the case of a fully charged battery).




The above is the introduction of why the drone battery can not exceed 30 minutes brought to you by the drone battery manufacturer Encore Energy.
