Long-distance charger and long-distance charging system

Abstract

The invention relates to the technical field of long-distance charging, and particularly discloses a long-distance charger and a long-distance charging system. The long-distance charger comprises an energy converter, a positioner and a storage battery; the positioner is separated from the energy converter by a set position distance, and real-time position information of the long-distance charger is obtained through positioning and sent; the energy converter comprises a shell which is a shell provided with a hollow charging cavity, wherein an energy collection hole for receiving an energy signal is formed in the side wall of the shell; an energy conversion array which is located in the charging cavity and used for receiving the energy signal and converting the energy signal into electric energy; and a conductive transmission line which is connected between the energy conversion array and the storage battery and is used for unidirectionally transmitting the electric energy to the storagebattery. According to the long-distance charger and the long-distance charging system, ultra-long-distance real-time charging can be achieved, a large-size battery does not need to be arranged, the load and the cost are reduced, and the long-distance charger and the long-distance charging system are suitable for unmanned aerial vehicles, unmanned ships and other devices with long-time endurance requirements.

Description

technical field [0001] The invention relates to the technical field of long-distance charging, in particular to a long-distance charger and a long-distance charging system. Background technique [0002] With the popularity of electronic products and the explosive growth of electric vehicles, wireless charging can overcome the current problems of cable charging such as aesthetics, cost, and limited charging distance, and has gradually become an urgently needed technology. At present, wireless charging technologies released by Samsung, Huawei, Apple, etc. are based on Faraday's electromagnetic induction principle. By providing a certain frequency of alternating current to the power transmitting coil to generate a magnetic field with constantly changing magnetic flux, the power receiving coil will generate an induced current, and then shape it to realize the charging of the battery. The power transmitting coil and the power receiving coil only need to be aligned with each othe...

Problems solved by technology

However, in the wireless charging technology based on Faraday's electromagnetic induction principle, only some short-distance wireless charging can be realized. Magnetic problems, low magnetic field utilization, low charging efficiency, and radiation problems

In addition, drones, unmanned ships and other devices that have long-term continuous battery life requirements are generally far away from the charging device during exercise, and most of the time far exceeds the distance of 1.2 meters, and it may happen at any time. When changing one's own position, it is difficult to achieve this long-distance wireless charging demand through traditional electromagnetic induction wireless charging, so it is necessary to design a long-distance wireless charging solution to solve these problems
