Problems solved by technology

However, the voltage on the low-voltage side of the transformer of the charging station designed by this integrated charging station is 380V. Due to the size limitation of the transformer, the capacity of the transformer is difficult to guarantee, which will inevitably result in slower charging speed and longer charging time, which cannot meet the needs of fast charging, etc. shortcoming

Abstract

The invention discloses a multifunctional charging pile system based on a box type substation, and relates to the technical field of electrical engineering. Charging piles and the box type substation are integrated in an embedding manner so that the charging piles and the box type substation are integrated, and the line cost can be greatly reduced. By employing an integrated design scheme, problems of large requirement of the charging piles by electric vehicles and difficult reconstruction of the power grid can be solved in a process of rapid development of the charging piles, and a charging system can be directly assembled in a production workshop and then transported to a site for debugging.

Description

technical field [0001] The invention relates to the technical field of electrical engineering, in particular to a multifunctional charging pile system based on a box-type substation. Background technique [0002] In recent years, under the encouragement of national new energy and energy-saving policies, the development of various rechargeable vehicles and charging piles is on the rise. At the same time, the charging device for electric vehicles has become an important supporting infrastructure for the development of electric vehicles. Develop the construction of charging infrastructure to facilitate the use of electric vehicle owners. According to the documents of the National Energy Administration, by the end of 2016, the number of electric vehicles in my country was close to 1 million, and the total number of charging piles was 150,000. The current vehicle-to-pile ratio is 7:1, and the reasonable vehicle-to-pile ratio is 1. : Around 0.9, the number of charging piles in our...
