Wired and wireless hybrid DC charging system

Abstract

The invention relates to a charging system, and belongs to the technical field of a charging device. A wired and wireless hybrid DC charging system is characterized by comprising a wired and wireless universal module and a wireless charging module, wherein the wired and wireless universal module is provided with an input end and an output end and is used for achieving electric energy transmission and control under a wired mode, the input end is connected with a single-phase power frequency alternating current, the output end is connected with an electromobile, the wireless charging module is provided with an input end and an output end and is used for converting a direct current to an alternating current and completing wireless electric energy transmission, the input end is connected with the output end of the wired and wireless universal module, and the output end is connected with the electromobile. By the wired and wireless hybrid DC charging system, the requirement of DC fast charge of the electromobile is met, meanwhile, energy is supplemented to a wireless electromobile, uniform control and metering under two charging modes is achieved, the potential of charging facility is fully dug, and the requirements of reasonable layout, scientificness and efficiency are met. Two modes of wired charging and wireless charging are integrated, uniform management is facilitated, the construction cost is reduced, benefits are brought to people to the greatest extent, and market demand is satisfied.

Description

technical field [0001] The invention relates to a charging system and belongs to the technical field of charging devices. Background technique [0002] The electric vehicle energy supply system is an indispensable subsystem for the electric vehicle industry. When the power battery of the electric vehicle is consumed to a certain extent, the charging system must be used to supplement the power battery to provide energy for the operation of the electric vehicle. So as to meet the recycling of electric vehicles. At the same time, in order to promote and popularize electric vehicles on a large scale, it is necessary to build an energy supply system to enhance the public's interest and confidence in the use of electric vehicles. Therefore, the electric vehicle charging system is an important basic support system for electric vehicles, a key condition for realizing the industrialization and popularization of electric vehicles, and has a significant impact on the industrial develo...

AI Technical Summary

Problems solved by technology

At present, wired and wireless charging systems have begun to be laid across the country, but the two are in a state of separate operation, each has an independent management and measurement system, and the lack of overall coordination has caused confusion to a certain extent

The number of electric vehicles based on wired and wireless charging has further increased, and the disadvantages of separate operation have become more and more obvious: unified management, lack of reasonable planning, large footprint, cost waste, poor economy, poor user experience, etc., so the unified management of the two imminent
