specific Embodiment approach 1

[0027] Specific implementation mode one: see Figure 1 to Figure 4 Describe this embodiment, the magnetic pole winding type T-shaped power supply track applied to the wireless power supply of electric vehicles described in this embodiment, it includes a strip-shaped magnetic core 3, a power supply cable 2 and a plurality of T-shaped magnetic poles 1;

[0028] On the elongated magnetic core 3, a plurality of T-shaped magnetic poles 1 are arranged in sequence along the length direction of the elongated magnetic core 3 according to a preset interval d,

[0029] The preset interval d is between the tail end of the previous T-shaped magnetic pole 1 and the head end of the subsequent T-shaped magnetic pole 1 among the two adjacent T-shaped magnetic poles 1 along the length direction of the elongated magnetic core 3 distance,

[0030] The power supply cable 2 adopts the magnetic pole winding method. The winding arrangement of the power supply cable 2 is divided into upper and lower ...

specific Embodiment approach 2

[0036] Specific implementation mode two: see Figure 1 to Figure 4 Describe this embodiment. The difference between this embodiment and the pole-wound T-shaped power supply track applied to electric vehicle wireless power supply described in the first embodiment is that the T-shaped magnetic pole 1 is a T-shaped structure, and the power supply cable 2 Winding on the vertical bar of the T-shaped structure.

[0037] In this embodiment, the T-shaped structure greatly saves the raw materials required for the production of the power supply track, and at the same time greatly reduces the difficulty of construction.

specific Embodiment approach 3

[0038] Specific implementation mode three: see Figure 1 to Figure 4 Describe this embodiment. The difference between this embodiment and the magnetic pole-wound T-shaped power supply track applied to electric vehicle wireless power supply described in the second embodiment is that the horizontal bar of the T-shaped structure is perpendicular to the long bar. The width of the magnetic core 3 in the length direction is greater than or equal to the width of the elongated magnetic core 3 .

[0039] In this embodiment, the width of the power supply track 3 is very narrow, which greatly saves the raw materials required for the production of the power supply track, and at the same time greatly reduces the difficulty of construction.

Abstract

A magnetic pole winding type T-shaped power supply track applied to wireless power supply of electric cars is disclosed, belonging to the technical field of wireless electricity energy transmission of electric cars. The magnetic pole winding type T-shaped power supply track solves the problems of high track width, bad electromagnetic compatibility, severe magnetic flux leakage, higher electromagnetic radiation level on two sides of roads and high difficulty in construction in the existing wireless electricity energy transmission apparatuses for the electric cars. The magnetic pole winding type T-shaped power supply track comprises long-stripped magnetic cores, power supply cables and a plurality of T-shaped magnetic poles; the T-shaped magnetic poles are arranged on the long-stripped magnetic cores in sequence at the preset interval d in the length direction of the long-stripped magnetic cores; the power supply cables are wrapped in an upper layer and a lower layer; the power supply cables in the upper layer are arranged from the head end to the tail end of the long-stripped magnetic cores for winding the T-shaped magnetic poles in sequence; the power supply cables in the lower layer are arranged from the tail end to the head end of the long-stripped magnetic cores for winding the T-shaped magnetic poles in sequence; and the tail end of the power supply cables in the upper layer is connected with the head end of the power supply cables in the lower layer. The magnetic pole winding type T-shaped power supply track is mainly applied to the electric cars.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle wireless power transmission. 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 occupy a large amount of ground area, are not conducive to unified management, and have high operat...
