Problems solved by technology

There are two disadvantages in the battery power supply mode. One is that there are many problems such as the volume, weight, price, material, safety, charging speed, and life of the battery.
[0003] These shortcomings bring difficulties to the industrialization of electric vehicles
The other is the charging infrastructure problem on the ground. On the one hand, due to the long charging time, a large number of charging or battery replacement facilities are required. These facilities need to occupy a large amount of ground area and require frequent maintenance. On the other hand, it is reflected in the equipment Need to stop and charge frequently, which lowers the operating efficiency of the equipment

Abstract

The invention discloses segmentation overlapped auto-decoupling rectangular coil structured power supply equipment applied to wireless power supply for mobile transportation equipment, belongs to the technical field of magnetic coupling resonant type wireless electric energy transmission, and satisfies requirements of efficient and safe wireless power supply in a mobile transportation equipment operating process. a sections of power supply tracks are formed by a rectangular coils; the a rectangular coils are tiled and arranged along the actual movement direction; the back end of a previous one rectangular coil is pressed by the front end of the next rectangular coil, and the overlapped regions are equivalent in width; the width d of the overlapped region of the adjacent rectangular coils is less than times of a formula as shown in the specification of the length L of the rectangular coils; the directions of the magnetic fields generated by the adjacent rectangular coils are the same; c inverting power supplies are used for supplying power to the a rectangular coils through b control boxes; and the b control boxes are used for controlling whether the a rectangular coils are powered on or not, and one control box concurrently controls whether two rectangular coils are powered on or not. The segmentation overlapped auto-decoupling rectangular coil structured power supply equipment is applicable to wireless power supply for electric vehicles.

Description

technical field [0001] The invention belongs to the technical field of magnetic coupling resonant wireless power transmission. Background technique [0002] With the increasing awareness of low-carbon environmental protection and green energy saving, more and more mobile transportation equipment uses electric energy as its power source. Common power supply methods include sliding contact type, cable drag chain type and battery-powered type. Among them, the sliding contact method has low safety reliability and high maintenance cost, and the cable drag chain type has strict restrictions on the moving distance, and the use environment is very limited. In the case where the flexibility of the device is required to be high, it is usually powered by a battery. There are two disadvantages in the battery power supply mode. One is that there are many problems such as the volume, weight, price, material, safety, charging speed, and life of the battery. [0003] These shortcomings br...
