Problems solved by technology

A regressive idea is to use a DC motor to drive a generator instead of an AC-DC circuit or a DC-DC circuit, but the power conversion efficiency of this technical idea is low. For this reason, the industry has proposed a variety of ideas for auxiliary mechanical energy devices, such as in Generator shaft plus flywheel

Embodiment 1

[0053] A charging pile system, including electric wheel 1, motor 2, magnetic moment wheel 3, generator 5 and rectification device; motor 2 is a rotary AC motor with a nominal 220V, and its power control terminal is connected to a conventional civilian 220V city network AC power supply The rotating shaft of the motor 2 is fixedly connected with the rotating shaft 1a of the electric wheel 1, and drives the electric wheel 1 to rotate in a shaft transmission mode; Figure 4 As shown (static diagram): the material of the electric wheel 1 is plastic steel, and 4 moving magnets 1c are evenly arranged around the wheel rim 1b at intervals, and the N poles of the moving magnets face the rotating shaft 1a, and the S poles face the outer edge (such as figure 2 As shown), the arc distance between the outer edges of the moving magnet is m; the material of the magnetic moment wheel 3 is a non-magnetic alloy, and eight rotating magnets 3c are evenly arranged around the wheel rim 3b, and the S p...

Embodiment 2

[0057] All the magnetic pole directions of the electric wheel 1 described in Embodiment 1 are replaced, that is, the S pole of the moving magnet 1c arranged around the rim 1b of the electric wheel 1 faces the rotating shaft 1a, and the N pole faces the outer edge; the rest of the components and structures remain unchanged.

[0058] In this embodiment, the magnetic poles of the moving magnet 1c of the electric wheel 1 and the rotating magnet 3c of the magnetic moment wheel 3 are arranged in the same way, all of which are S poles facing the rotating shaft 3a and N poles facing the outer edge, so that the electric wheel 1 and The force shown by the change of the magnetic field distribution state between the rotating magnets 3c is mutual repulsion; when the city power grid supplies power to the motor 2 to drive the electric wheel 1 to rotate, the rotation of the moving magnet 1c around the axis 1a will generate a magnetic force along the rotating magnet 3c The magnetic repulsion fo...

Embodiment 3

[0060] The charging pile system of Embodiment 1 is technically deformed, and two magnetic moment wheels 3 are set. The rotating magnets 3c on the rims 3b of the two magnetic moment wheels are distributed in the same way, and the rotating shafts 3a of the two magnetic moment wheels are respectively fixed and installed on the same On the rotating shaft, it can be regarded as a magnetic moment wheel 3 with reference to the shaft longitudinal direction; at the same time, two electric wheels 1 are respectively arranged corresponding to the two magnetic moment wheels 3, and the moving magnets 1c on the two electric wheel rims 1b have the same distribution, The rotating shafts 1a of the two electric wheels are respectively fixedly installed on the same rotating shaft, so that they can be regarded as one electric wheel 1 with reference to the shaft longitudinal direction. During installation, the plane centerlines 11 of the two electric wheels 1 coincide with the plane centerlines 33 o...

Abstract

A charging pile system of the present invention comprises an electric wheel, an motor, a magnetic moment wheel, a generator and a rectifying apparatus; the motor is connected to a power of a conventional urban and rural power supply network or other power; at least four moving magnets are evenly distributed around a rim on the electric wheel, and an arc spacing between outer edges of the moving magnets is m; at least four rotating magnets are evenly distributed around the rim on the magnetic moment wheel, and the arc spacing between the outer edges of the rotating magnets is n; m and n are equal; the motor is in transmission connection with the electric wheel; the electric wheel is arranged adjacent to the magnetic moment wheel; the magnetic moment wheel is in transmission connection withthe generator; the generator is connected to the rectifying apparatus; when the motor drives the electric wheel to rotate, a distribution state of a gap magnetic field inside the charging pile systemchanges reciprocally, so that the magnetic moment wheel obtains a torque to drive the generator to rotate and generate power, and a load of the charging pile system is charged by the rectifying apparatus.

Description

technical field [0001] The invention relates to the specific application design field of charging piles, in particular to a charging pile system that does not use conventional AC-DC or DC-DC circuits for electric energy conversion. Background technique [0002] The early application of charging piles was based on the concept of the need to establish a charging network for urban electric vehicles. With the development of charging pile technology, it is believed that charging piles can cut peaks and fill valleys for urban power grids, or be used in conjunction with wind energy and solar energy devices. More missions with new energy as the theme. [0003] In the technical solution for the specific application of charging piles, it is usually necessary to convert AC power into DC power and adjust the output voltage up / down. The current mainstream technology application is to use AC-DC circuits or DC-DC circuits, and this The AC-DC circuit or DC-DC circuit implies a high-frequen...
