In 2011, the U.S. Department of Defense’s Advanced Research Projects Agency also tried wireless charging within two meters, about 6.6 feet. The result was not satisfactory. For this wireless charger, although 50 feet is a small distance, this length is a perfect length for actual consumption and military systems. Under normal circumstances, the farther the coil is required to transmit electricity, the thicker the coil is, but if it is too thick, it is not convenient for the soldiers to carry it. So the key to the problem lies in the realization of the resonance of the coil repeater, so that “electric energy†can jump from one repeater to another, and the cycle jumps and the coil size can be reduced. The history of wireless charging can be found in 2007, when MIT tried to transmit 60 watts of electricity within two meters and successfully delivered half of the power, using a "strongly coupled magnetic resonator." In general, the wireless charging distance will be affected by the power inductor and the actual distance. The size of the resonator coil in the MIT test is similar to the size of the refrigerator coil, but that can only support about two meters. Once space is charged, the soldiers will no longer have to go back to the base to charge. They only need to carry the wireless charging device with them. Under further assumptions, if this technology continues to develop, it is very likely that it will be used on unmanned aircraft one day, and even further spread into our lives, so that technology will continue to affect our lives. The popularity and advancement of electronic devices have brought us convenience while allowing us to face more problems. For example, when you go out and carry a cell phone, a camera, or a computer, you also need to bring a bunch of chargers and data cables. Once the battery runs out in an emergency, things get messy. Therefore, the development of high-tech batteries has not stopped. The newly emerged wireless charger has brought us good news. It is reported that the U.S. Department of Defense is considering using wireless charging instead of wired chargers, with an initial set distance of 50 feet. At present, the plan has invested 5-6 million US dollars for the R&D center to increase the effectiveness of long-distance air-to-air charge. Once the plan is successful, soldiers will not need to go back to the base to charge, just carry a wireless rechargeable battery with them, either at the base or The battlefield can be charged at any time; imagine that if this technology develops further, it is very likely that it will be used on unmanned aircraft one day, and even further spread into our lives. In general, the wireless charging distance will be affected by the power inductor and the actual distance. The size of the resonator coil in the MIT test is similar to the size of the refrigerator coil, but that can only support about two meters. The US Department of Defense’s Advanced Research Projects Agency also said that after preliminary tests, if a metal object is nearby when charging, it will cause charging interference, but you can add a plastic or glass case to the surface of the wireless charger to reduce interference.
