Embodiment 1

[0032] A three-phase launch rail applied to dynamic wireless power supply of electric vehicles, such as figure 1 As shown, the three emission guide rails include a strip magnetic core, a power supply cable and a plurality of π-shaped magnetic poles; the plurality of π-shaped magnetic poles are arranged on the strip-shaped magnetic core, and The length direction of the cores is arranged sequentially according to the preset interval d; the power supply cable is wound on the two vertical bars of the π-shaped magnetic pole, and the π-shaped magnetic pole structure arranged longitudinally forms a long straight track.

[0033] Wherein, the preset interval d is the distance between the tail end of the previous π-shaped magnetic pole and the means of the next π-shaped magnetic pole among the two adjacent π-shaped magnetic poles; the distance range of the preset interval d It is 10cm to 50cm, and its interval is positively correlated with the length of the top surface of the π-shaped ...

Abstract

The invention relates to a three-phase launching guide rail applied to dynamic wireless power supply of an electric car and belongs to the technical field of wireless power energy transmission of theelectric car. The three-phase launching guide rail comprises multiple pi-type structures, strip-shaped ferrite magnetic cores longitudinally arranged according to a certain interval, multiple pi-typemagnetic pole structures formed by power supply cables wound around vertical rods of the pi-type magnetic cores, and a long straight type track formed by longitudinally arranging magnetic poles threeof which form one group according to the design interval. The three-phase launching guide rail has the characteristics that magnetic leakage is extremely small, and the electromagnetic compatibility is good.

Description

technical field [0001] The invention relates to a three-phase transmitting guide rail applied to dynamic wireless power supply of electric vehicles, belonging to the technical field of wireless power transmission of electric vehicles. Background technique [0002] At present, there are two bottlenecks in the development of electric vehicles: one is the battery problem on the car-from the perspective of recent technology, there are many problems such as volume, weight, price, material, safety, charging speed, and lifespan. The cyclic process of production and use is a process of high pollution, resource consumption, and damage to the ecological environment. These characteristics bring difficulties to the industrialization of electric vehicles; [0003] On the other hand, there is the problem of charging infrastructure on the ground-due to the limitation of battery material characteristics (energy density, power density, etc.), the battery charging time is long and the cruisin...
