Abstract

The invention discloses a concentrated direct-current power supply skid-mounted electric automobile charging device. A solid insulating ring network cabinet is arranged in a high-voltage chamber; a dry transformer is arranged in a transformer chamber; a low-voltage switch cabinet, a monitoring cabinet, an AFE (analog front end) and a charger are arranged in a low-voltage distribution chamber; a hoisting hanging point is formed at the bottom of a charging house; a grounding copper bar is arranged at the bottom of the charging house; an air-conditioning outdoor unit chamber is arranged above the transformer chamber and used for assembling an air-conditioning outdoor unit; and the outer wall of the charging house is provided with wire inlet and outlet holes. The device has the advantages of concentrated rectification, dispersed direct-current power supply, direct supply of direct-current power supply to multiple chargers after the alternating current is converted into direct current by adopting rectification of the AFE, high power factor, low current harmonic content, no influence on power quality of a power grid, capability of directly connecting the electrical energy generated by new energy generating equipment of solar energy, wind energy and the like to a direct-current bus, small volume and high protection level due to the use of a skid-mounted house body, integral field assembly, convenience for transportation, and waterproof, fireproof and wind-sand resistant properties of the house body.

Description

technical field [0001] The invention belongs to the field of charging energy for electric vehicles, in particular to a skid-mounted electric vehicle charging device with centralized DC power supply. technical background [0002] With the progress of society, the number of cars is increasing rapidly. At the same time, the consumption of oil is also increasing rapidly, which brings a series of problems such as energy shortage, environmental pollution, and rising oil prices. The development of electric vehicles and the use of clean energy can effectively alleviate problems such as energy shortages and environmental pollution. Therefore, the country is vigorously promoting and promoting electric vehicles. An important bottleneck in the promotion of electric vehicles is the charging problem. For this reason, the country plans to build electric vehicle charging stations and carry out pilot work in some important cities. [0003] The main problems faced in the construction of char...
