Electric vehicle charging pile load interactive control system and application method thereof

Abstract

The invention discloses an electric vehicle charging pile load interactive control system which comprises an interactive system main station, client interactive terminals and charging pile terminals,and is characterized in that the interactive system main station is in electric signal connection with the charging pile terminals and the client interactive terminals, and the charging pile terminalsare in electric signal connection with a transformer and switches; the transformer is in electric signal connection with the switches, the switches are in electric signal connection with the chargingpiles, and the number of the client turntable terminals and the number of the charging piles are both multiple. From the perspective of an intelligent power grid, the supply and demand relationship can be balanced, and the reliability of the system is improved; from the perspective of users, economic returns and benefits can be obtained by adjusting or changing the modes of using and purchasing electric power; from the perspective of the environment, energy conservation and emission reduction are facilitated, and increasingly serious energy crisis is relieved.

Description

technical field [0001] The invention relates to the technical field of control systems, in particular to an interactive load control system for electric vehicle charging and swapping piles and an application method thereof. Background technique [0002] At present, with the increasing popularity of electric vehicles, the number of charging piles is also increasing. The design and installation of charging piles are considered in the planning stage of new communities, and charging piles are gradually installed in old communities in a planned way. The access of a large number of charging piles brings the risk of heavy overload to the distribution transformer. Especially after get off work, customers concentrate on charging vehicles, and the electricity consumption of households in residential areas also increases, which brings challenges to the capacity of transformers and forms peak electricity consumption, especially in summer. [0003] At present, the solution to this probl...

The access of a large number of charging piles brings the risk of heavy overload to the distribution transformer

Especially after get off work, customers concentrate on charging vehicles, and the electricity consumption of households in residential areas also increases, which brings challenges to the capacity of transformers and forms peak electricity consumption, especially in summer

[0003] At present, the solution to this problem is to cut off the power and increase the capacity of the transformer

However, this method not only greatly increases the cost of the power supply enterprise, but also cannot achieve the effect of real-time adjustment, and the lag is obvious, which is not conducive to the timely solution of the problem
