Microgrid energy storage-based wireless charging apparatus and method for pure electric ship

Abstract

The invention relates to a microgrid energy storage-based wireless charging apparatus for a pure electric ship. The direct current output end of a microgrid system is connected with the direct current input end of a chopping wave power oscillator; the alternating current output end of the chopping wave power oscillator is connected with the signal input end of an electromagnetic field transmitting coil module; the signal input end of a chopping wave power oscillation controller is connected with the signal output end of the chopping wave power oscillator; the control signal output end of the chopping wave power oscillation controller is connected with the control end of the chopping wave power oscillator; the signal output end of an electromagnetic field receiving coil module is connected with the signal input end of a rectifying and filtering chopper; the signal output end of the rectifying and filtering chopper is connected with the signal input end of an electric energy storage apparatus; and the charging end of the electric energy storage apparatus is used for charging the pure electric ship. The invention provides a novel microgrid energy storage-based wireless charging way, which is energy-saving, environment-friendly, and high in efficiency, for the pure electric ship.

Description

technical field [0001] The invention relates to the technical field of charging equipment for pure electric ships, in particular to a wireless charging device and method for pure electric ships based on microgrid energy storage. Background technique [0002] With the continuous improvement of my country's economic strength, the problems of energy structure and environmental pollution are increasingly emerging. In order to maintain the sustainable development of the economy and society and solve the dual problems of energy supply and ecological environment protection, the Chinese government has successively issued a number of policies on energy conservation and environmental protection, and actively promoted the optimization of my country's energy structure. At present, the country's call for energy conservation, environmental protection and optimization of energy structure has been deeply rooted in the hearts of the people. [0003] The charging method of pure electric ship...

AI Technical Summary

Problems solved by technology

[0003] The charging method of pure electric ships generally adopts the charging method of wired charging piles. This method requires a long cable connection and a long cable connection time, which leads to a limited number of ships charged per unit time, lack of economy, and directly affects Promotion of pure electric ships
