Specific embodiment
The specific technical solution of the present invention is further described with reference to the accompanying drawings of the specification.
As shown in Fig. 1, a kind of flexible multimode regulating switch regulating system for charging vehicle power distribution network of the invention,
Including emanant power distribution network, TVR2, charging transmitting terminal 3, charging receiving end 4 and ferry-boat charging vehicle 5, which is characterized in that
The TVR2 is connected between power transformation output end 1 and emanant power distribution network,
The charging transmitting terminal 3 is connected to emanant power distribution network user terminal, and charging transmitting terminal 3 includes Laser emission battle array
Arrange, be trapped among the magnetic anti-leak coaming plate and camera of Laser emission array surrounding, the front end face of the magnetic anti-leak coaming plate
It is upper that there is magnetic suction item.The laser emitter of the Laser emission array is pulse laser.The camera is for filling
Electric transmitting terminal and receiving end precisely align.Alignment methods can wish other technology using image in the prior art, use camera
Photovoltaic array image is shot, the controller of movable charging vehicle is sent back, finds out center, with the center of Laser emission array
Position compares.
The charging receiving end 4 includes the photovoltaic array and photovoltaic for being mounted on ferry-boat 5 tail body outer surface of charging vehicle
The magnetic of array surrounding inhales item, the surface of the photovoltaic array and ferry-boat 5 tail body outer surface fairing of charging vehicle, photovoltaic array four
The magnetic item of inhaling in week is corresponding with the magnetic item of inhaling on the front end face of the magnetic anti-leak coaming plate, and magnetism, which inhales item, can be used electricity
Magnet, when not being attracted, laser beam is not exported, and avoids hair leakage accident.
The ferry-boat charging vehicle 5 has energy-storage lithium battery group, which connect with charging receiving end 4, stores up
Energy lithium battery group is the solid-state titanium lithium battery of large capacity.
The course of work of system of the invention be it is such, the user terminal of power distribution network is arranged in be easy to stop safety,
Ward, ferry-boat charging vehicle 5 can be middle-size and small-size car or motorbus, depending on charge requirement.Usually, ferry-boat charging vehicle
5 just park or charge in its place of charging, if what Rechargeable vehicle user need to be charged with mobile terminal to cloud server transmission
Electric car position, then send the ferry-boat charging vehicle 5 of electric power abundance be moved to the electric car that need to charge nearby to electric car into
Row charging.
The charging process of ferry-boat charging vehicle 5 is to be directed at charging transmitting terminal 3 with charging receiving end 4, make photovoltaic array surrounding
