An electric vehicle coordinated charging system and its self-decision method

Abstract

The invention requests to protect a residential community electric automatic decision-making charging system and method. The residential community electric automatic decision-making charging system comprises a plurality of charging piles, each charging pile carries a control module and is connected with a concentrator via a power line, and the concentrator is connected with an electricity utilization information collecting system via the power line. The concentrator carries a main control module, the main control module collects real time electricity price information and current residential community electrical load information from the electricity utilization information collecting system, and charging pile configuration information and working condition information can be obtained from the charging piles in a residential community; a charging strategy is made based on priorities, charging power can be adjusted dynamically in charging processes, and electrical loads in the residential community can be maintained at a safe level while electricity demand of users can be met. Decisions are made via the charging system in the residential community in whole operation processes, operating states of a power grid of the residential community can be reported to a main station in a timed manner, a step of waiting for control instructions issued by the main station is not required, some complex instruction scheduling processes can be prevented, operating efficiency is improved, and burdens of the main station can be alleviated.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to a control system and method for charging piles in a residential area. Background technique [0002] Today, as a clean new energy vehicle, electric vehicles are receiving more and more attention and response. As the number of electric vehicles in ordinary residential quarters continues to increase, problems also follow. Due to the lack of necessary control means for the power system in the community, when the peak period of electricity consumption arrives, when many electric vehicles in the community are charging at the same time, it is very easy to cause the community to The overload of electricity consumption threatens the safety and stability of electricity consumption in the community. If the capacity of power equipment in the community is specially increased to cope with peak power consumption, it will increase the cost of power consumption and reduce the u...

AI Technical Summary

Problems solved by technology

[0003] In the existing research, the optimal charging method for electric vehicles in the community environment is mainly based on electricity price guidance, load forecasting, and optimal scheduling. As far as the residential area is concerned, although it can theoretically solve the problem of charging in the residential area, the implementation process is cumbersome. If a large number of residential areas adopt this method, the upper master station will be overwhelmed
