AC-DC charging pile interface conversion device for underground parking lot

Abstract

The invention belongs to the technical field of new energy vehicles, and particularly relates to an AC-DC charging pile interface conversion device for an underground parking lot. The AC-DC charging pile interface conversion device comprises a main box. A first transformer, a second transformer, a third transformer, a first rectifier bridge, a second rectifier bridge and a third rectifier bridge are fixedly connected to the inner bottom wall of the main box. A charging port is formed in the surface of one side of the main box, the inner wall of the charging port penetrates through and extendsto the inner side wall of the main box, and a charging socket is fixedly connected to the inner wall of the charging port. According to the AC-DC charging pile interface conversion device for an underground parking lot, when a first contact piece contacts a first upper contact block and a second contact piece contacts a first lower contact block, a second upper contact block, a second lower contact block, a third upper contact block, a third lower contact block, a fourth upper contact block and a fourth lower contact block are in contact with an insulating disc, and other power supplies cannotform a closed circuit and cannot be intersected with a connected circuit, so that the device has the effect that other circuits are disconnected when one power supply is connected.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to an interface conversion device for AC and DC charging piles in an underground parking lot. Background technique [0002] With the consumption of non-renewable energy all over the world, various resources are increasingly depleted. As the country calls for the development of new energy, clean energy and renewable energy. A variety of new energy products have emerged, including new energy vehicles. As far as the current technology and development prospects are concerned, the market for electric vehicles is unprecedentedly broad. [0003] As we all know, there are roughly two charging modes for electric vehicles. One is AC and the other is DC. The so-called AC charging is what people often call slow charging. Using the car charger to directly connect to the mains has the advantage of less damage to the battery, and the disadvantage is that the charging speed is slow....
