Rapid electric vehicle wireless charging system based on superconducting alloy

Abstract

The invention discloses a rapid electric vehicle wireless charging system based on superconducting alloy. The wireless charging system comprises a charging adjustment control system, a wireless charging sending device and a wireless charging receiving device. The interior of charging adjustment control system is divided into an intermittent pulse charging system, a variable current intermittent charging system and a variable voltage intermittent charging system. According to the invention, the charging adjustment control system is used for carrying out charging system adjustment on charging batteries in different states, so the rapid charging mode of the batteries is quite highly efficient; a built-in charging chip and a battery protection chip are used for carrying out charging adjustment control on a wireless charging device, so the charging batteries are protected against damage caused by overvoltage and overcurrent in charging; the niobium-titanium superconducting alloy is used for carrying out mutual-inductance electric energy exchange, so charging conversion efficiency is greatly improved; and meanwhile, copper-nickel alloy is wrapped around the external layer of the niobium-titanium superconducting alloy, so neighborhood coupling effects between chip filaments and resistance scattering of the superconducting alloy are avoided.

Description

technical field [0001] The invention belongs to the field of wireless charging technology systems, in particular to a fast electric vehicle wireless charging system based on superconducting alloys. Background technique [0002] A superconducting material refers to a material that exhibits the properties of zero resistance and repelling magnetic lines of force under certain low temperature conditions. Alloy superconducting materials refer to the fusion of two or more metal elements to form superconducting materials with superconductivity. There are 27 kinds of metal elements that are superconducting, and their Hc and Jc are relatively low. The Hc2 of the lead-bismuth (Pb—Bi) eutectic alloy discovered in 1930 is less than 2T. Later, it was discovered that thousands of alloys are superconducting substances, but only a few have practical value. Alloy superconducting materials with practical value are almost all niobium-based alloys, mainly including niobium-zirconium (Nb-zr), ...

[0003] Nowadays, electric vehicles have become an important means of transportation for most people to travel. The application and popularization of electric vehicles make people's work and life more convenient, but electric vehicles need to be charged. The traditional charging method is not only slow, but generally takes 7- 10 hours, and the charging conversion rate is low, and the charging method is inconvenient. How to improve the charging efficiency of electric vehicles and make the charging method more convenient has become an important process to improve the convenience of people's travel
