Hollow T-shaped power supply track applied to wireless power supply of electric vehicles and track equipment containing the power supply track

Abstract

The invention relates to a hollow T-shaped power supply rail applicable for wireless power supply to an electromobile and a rail device containing the power supply rail, belonging to the technical field of wireless power transmission and aiming at achieving the purpose of improving system performance during wireless power supply to the electromobile. In the hollow T-shaped power supply rail applicable for wireless power supply to the electromobile, magnetic poles are hollow blocks with rectangular cross sections, and the two ends of the top side of the rectangle simultaneously extend outwards; the bottoms of all magnetic poles are fixed on a magnetic core, all magnetic poles are sequentially arranged along the length direction of the magnetic core, and the distance between adjacent two magnetic poles is equal; the bottom width of the magnetic pole is equal to the width of the magnetic core; a power supply cable is divided into a left-side cable and a right-side cable; the left-side cable is wound around all magnetic poles in a sine wave manner; the right-side cable and the left-side cable are wound around all magnetic poles in a mirror symmetric manner; and the left-side cable and the right-side cable are connected at one end of the rail. The hollow T-shaped power supply rail is applicable for the field of wireless power supply to the electromobile.

Description

technical field [0001] The invention belongs to the technical field of wireless power transmission, and in particular relates to a hollow T-shaped power supply rail applied to electric vehicle wireless power supply. Background technique [0002] At present, there are two major bottlenecks in the development of electric vehicles. One is the battery on the vehicle. From the perspective of recent technology, there are many problems such as volume, weight, price, material, safety, charging speed, and lifespan. In addition, the production of batteries The process is a process of high pollution, resource consumption, and damage to the ecological environment. These characteristics bring difficulties to the industrialization of electric vehicles; the other is the problem of charging infrastructure on the ground. On the one hand, due to the long charging time, a large amount of charging or Power exchange facilities bring great difficulties to municipal construction. These facilities ...

[0002] At present, there are two major bottlenecks in the development of electric vehicles. One is the battery on the vehicle. From the perspective of recent technology, there are many problems such as volume, weight, price, material, safety, charging speed, and lifespan. In addition, the production of batteries The process is a process of high pollution, resource consumption, and damage to the ecological environment. These characteristics bring difficulties to the industrialization of electric vehicles; the other is the problem of charging infrastructure on the ground. On the one hand, due to the long charging time, a large amount of charging or Power exchange facilities bring great difficulties to municipal construction. These facilities occupy a large amount of ground area, are not conducive to unified management, and have high operation and maintenance costs. On the other hand, electric vehicles need frequent parking and charging, which brings great inconvenience It is a great inconvenience, and the short mileage makes it impossible to travel long distances
