Control method capable of gradually increasing topological structure of charging circuit of charging pile

Abstract

The invention discloses a control method capable of gradually increasing a topological structure of a charging circuit of a charging pile. The invention relates to a charging pile control method. Themethod comprises a control step and a charging step. In the control step, when the number of charging piles needs to be increased, the charging piles are connected with idle relays in a reserved high-power relay concentration box through reserved wiring pipes, and then the control parts of the charging piles are connected with a regional control box through signal lines. According to the invention, the charging piles can be flexibly added and the charging interface can be reserved. In addition, due to the reserved wiring pipes, the charging piles can only be connected with idle relays in the reserved high-power relay concentration box, so random lap joint of cables or additional arrangement of other high-power relay concentration boxes can be avoided, safety risks are reduced, and the control method is more independent and unique in use and better in stability.

Description

technical field

[0001] The invention relates to a method for installing a charging pile, in particular to a method for controlling the topological structure of a charging circuit that can gradually increase the charging pile. Background technique

[0002] In the "Technical Standards for Distributed Charging Facilities for Electric Vehicles" officially implemented on March 1, 2019, it is required that 100% of parking spaces for electric vehicles should be equipped, which is for new residential buildings. With the development of electric vehicles, there is a demand for the construction of charging piles not only for new residential buildings, but also for established communities. However, due to the problems of property rights and many owners in the built communities, the degree of demand for charging piles and the completion time of demand are also different. different.

[0003] As a result, it is difficult to build charging piles in one step in the built-up community. In di...
