Storage battery wireless charging minimum connecting device

Abstract

The invention discloses a storage battery wireless charging minimum connecting device. The device comprises a high-frequency inverter power supply, an energy transmitting system, an energy receiving system, an energy coupling coil, a load side, a power detection circuit and a battery energy management system, wherein the energy transmitting system and the energy receiving system are coupled in a resonant mode, and the load side comprises a rectification voltage stabilizing system, a storage battery and a power variation load; and the high-frequency inverter power supply adjusts the energy output power according to the real-time power of the power variation load, starts energy output according to a relationship between the real-time resistance value of the storage battery and a set charging frequency and provides power for the energy transmitting system. The storage battery wireless charging minimum connecting device provided by the invention is simple in principle and convenient to adjust, can be popularized to a minimum regulation method after various types of loads are connected with a wireless energy transmission system, and a related minimum connecting technological problem of the wireless energy transmission system is basically solved.

Description

technical field [0001] The invention relates to a minimum access device for wireless charging of a storage battery, which can be adjusted in real time according to changes in load power and whose charging frequency can be set once, and input wireless energy transmission technology. Background technique [0002] In recent years, with the continuous improvement of people's living standards and the gradual deepening of exploration of the material world, people have new requirements for the transmission method and quality of electric energy. Traditional power transmission is mainly carried out by direct contact of wires or conductors. Sparks generated by contact, sliding wear, carbon accumulation and exposed charged conductors have brought a series of problems. Wireless power transmission is a technology that uses radio to transmit electric energy. It was first proposed by Nikola Tesla. Compared with the traditional power transmission method, there is no direct connection betwee...
