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

Abstract

The invention discloses a charging pile system and a control method thereof. The charging pile system comprises an exciter, an electric device, a magnetic torque wheel, a generator and a rectifier. Atleast four rotate magnets are arrange around that wheel rim of the magnetic torque wheel at intervals in the same N / S polarity, and the magnetic torque wheel and the generator are driven; The generator is connected with the rectifying device; The opposite magnetic polarity of the exciter and the rotating magnet is opposite; The electric device comprises a control module and a position sensor, wherein the power control terminal of the electric device is connected with a mains power supply or other power supplies; The position sensor is arranged near the fixed position of the magnetic torque wheel; The electric device is mechanically fixedly connected with the exciter and is arranged adjacent to the magnetic torque wheel; When the magnetic torque wheel rotates, the electric device controlsthe exciter to be located at the minimum gap or away from the magnetic torque wheel according to the relative position of the rotation of the rotating magnet, so that the magnetic torque wheel drivesthe generator to rotate and generate electricity through the reverse pole attraction, and the direct current is supplied through the rectifying device.

Description

technical field [0001] The invention relates to the field of application design of charging piles, in particular to a charging pile system designed based on the principle of mutual attraction between permanent magnets with opposite magnetic poles and a control method thereof. 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 ci...
