How to solve the problem of drone battery life?

How to solve the problem of UAV battery life? In recent years, with the development of science and technology, UAV has expanded from the military field to the civilian field, especially in the fields of agriculture, forestry, electricity and security. As the application of drones becomes more and more widespread, complex drone varieties appear on the market, but these drones have an obvious problem with limited endurance. Currently, lithium polymer batteries are an important driving force for drones on the market. The battery life is generally between 20 minutes and 30 minutes. However, due to different technologies, most batteries have a service life of less than 45 minutes, but the charging time is more than 1 hour. Because the UAV wants to reduce the take-off weight as much as possible, it cannot carry large-capacity heavy-duty batteries. After flying for more than 10 to 20 minutes, most drones have to be replaced by someone or plugged in a charging cable. Therefore, you must carry three or four batteries with you when you go out. This is a fatal flaw in the development of unmanned aerial vehicles, which greatly restricts the overall development of my country's unmanned aerial vehicle industry. To promote the sustainable development of the UAV market, it is urgent to solve the problem of UAV battery life. The battery life of drones is a shortcoming that restricts the development of the drone industry, and it is also a technical problem that countries around the world have to solve. At present, the research on battery life processing of drones generally has the following directions: First, the technology discussion on the limited life of fuel-powered drone batteries (1) The first multi-axis drone uses hydrogen fuel-powered batteries in 2015. In September, Singapore’s HUS company developed the world’s first multi-axis drone HYCOPTER using hydrogen fuel-powered batteries. It can fly continuously for 4 hours under no-load conditions, and can support 150 minutes even under 1Kg full load. Far exceeds the endurance of lithium battery drones. Due to the use of hydrogen fuel-powered batteries, the structure of the helicopter is also different from other UAVs. In addition to lithium polymer hydrogen batteries, HYCOPTER also has two tubular containers that can store 4L of hydrogen. During operation, temporary hydrogen is injected into the hydrogen fuel power cell. After a chemical reaction, electricity appears to drive a motor with several rotors. The HYCOPTER charged with hydrogen is suitable for a 3Kg lithium battery in terms of power. Unfortunately, HYCOPTER is still under development and has just been tested. Technical discussion on limited battery life of drones (2) Smart energy hydrogen fuel power battery In December 2015, the djiMatrice100 drone equipped with smart energy hydrogen fuel power battery flew for more than an hour. Assuming that standard batteries are used, the drone can only fly for 20 minutes at a time on a charge. Hydrogen fuel power cells convert hydrogen into electricity through a chemical reaction, and the by-product is water vapor. Because the fuel is stored in a small box that can be replaced within a few seconds, the drone can quickly refuel and take off after the fuel runs out. Smart Energy will showcase its engineering results at the Consumer Electronics Show in Las Vegas in January next year. The company hopes that the product will attract drone manufacturers to use fuel-powered batteries as a power option for drones. The company has no plans to supply the revised product to ordinary users. Secondly, solar panels (1) In 2010, the solar windsurfing panels and land-based laser advance drones (uavs) of the British Hefeng ultralight solar unmanned aerial vehicle (uavs) continued to break records for 14 days. Technical discussion on limited battery life of drones (2) In June 2014, the world's largest solar powered aircraft Solar Impulse 2 made its first flight in Penn, Switzerland. There are 17,000 ultra-thin and high-efficiency solar panels on the wings of this aircraft, with a wingspan of 72 meters. Solar powered aircraft is an aircraft that uses solar radiation as driving energy. The power equipment is composed of solar cells, DC motors, reducers, propellers and control equipment. Because the energy density of solar radiation is very small, in order to obtain satisfactory energy, a solar-powered aircraft must have a large surface area to absorb sunlight. Solar panels absorb energy during the day, allowing the aircraft to fly at night, greatly improving flight endurance. Lithium battery technology discussion on the limited battery life of different drones In September 2015, Tesla, a leader in the field of electric vehicles, launched a prototype drone for aerial photography. In terms of battery charging, Tesla is much more complicated. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
