Tyre-based novel electric-car in-drive wireless power supply system

Abstract

The invention discloses a tyre-based novel electric-car in-drive wireless power supply system which comprises a plurality of energy receiving components mounted on wheels of a car and a plurality of energy emission systems laid under the traffic lane. The energy emission systems are arranged along the driving direction at intervals; the energy emission systems generate electromagnetic fields nearby the surface of the traffic lane, and the car wheels with the energy receiving components sense energy generated from the electromagnetic fields and provide power to a driving electric car. A near-field coupling mode is adopted, radiation effect is low, height of the chassis of the car is unaffected, applicability of the car is high, the tyre-based novel electric-car in-drive wireless power supply system can be used in urban traffic system like the electric cars and buses, energy conservation and environment protection are benefited.

Description

technical field [0001] The invention relates to a wireless energy supply system for vehicles, in particular to a tire-based wireless power supply system for electric vehicles during driving. Background technique [0002] Electric vehicles are an emerging energy-saving and environment-friendly means of transportation. With the shortage of energy supply and the improvement of people's awareness of environmental protection, their market prospects are getting better and better, and related technologies are also developing rapidly. [0003] At present, electric vehicles are driven by electric motors, and batteries are their main energy source, which requires long-term charging under static conditions to meet the requirements of long-distance driving. The charging method mainly adopts the charging pile wired charging method, which has high requirements on the environment and has certain operational risks. [0004] In order to facilitate the charging of electric vehicles, wireless...

Problems solved by technology

However, it is still necessary for the vehicle to be charged for a long time when it is stationary, which affects the travel efficiency of the vehicle

[0005] The way vehicles obtain electric energy while driving has been used for a long time in trams and trolleybuses, but they need to erect cables in the air or lay road tracks. Vehicles lack flexibility and affect the beauty of the city, which is no longer a mainstream technology.

For the existing wireless driving vehicle power supply technology, it is necessary to install energy receiving components at the bottom of the vehicle, and it is necessary to reward the height of the chassis from the road to efficiently obtain wireless energy, which will weaken the ability of the vehicle to pass through obstacles
