Description

technical field [0001] The invention relates to the field of wireless charging for electric vehicles, in particular to a wireless charging system for electric vehicles based on the Internet of Things. Background technique [0002] Electric vehicle charging stations refer to stations that charge electric vehicles, similar to gas stations today. With the low-carbon economy becoming the main theme of my country's economic development, electric vehicles, as an important part of the new energy strategy and smart grid, and one of the strategic emerging industries determined by the State Council, will surely become the focus of the development of China's automobile industry and energy industry in the future . At present, the main charging methods of electric vehicles include charging piles for ordinary charging, charging stations for fast charging and battery swapping stations. However, these three methods have certain disadvantages, but the common defect is: the common standard p...

AI Technical Summary

Problems solved by technology

However, these three methods have certain disadvantages, but the common defect is: the common standard problem of wired connection

Most of the fast charging methods are DC charging, which takes tens of minutes for a single charge, and fast charging will reduce the service life of the battery, and the impact on the urban power grid cannot be ignored

The main problems in the way of battery replacement include the standardization of batteries for electric vehicles, the management of battery circulation, etc.
