Electric vehicle charging power supply intelligent distribution system and control method

Abstract

The invention relates to an electric vehicle charging power supply intelligent distribution system and a control method, a community transformer of the system is respectively connected with a current transmitter and a civil power end through a current transformer, the current transmitter is connected with a main control unit, and the civil power end comprises a plurality of charging piles and a community power utilization device which are connected in parallel; the current transformer is used for detecting the electric current of a civil electric end, the current transmitter is used for processing an output signal of the current transformer, and the electric load detection module is used for processing a signal from the current transmitter. The invention provides a feasible scheme for the charging pile to enter the residential area, the charging pile can enter the residential area only by a small amount of engineering on the premise that the capacity of an existing transformer of the residential area is not changed, the equipment investment cost is low, and use and maintenance are easy.

Description

technical field [0001] The invention relates to the field of electric vehicle charging, in particular to an intelligent distribution system and control method for electric vehicle charging power sources, and is a device for managing the electric energy used by multiple charging piles in a residential area, especially to ensure that the transformers in residential areas are not increased in capacity Under the premise, through the control of this device, each charging pile can realize orderly charging of electric vehicles when the transformer in the community is lightly loaded. Background technique [0002] With the country's increasing emphasis on environmental protection, energy conservation and emission reduction, the number of electric vehicles has increased rapidly. Electric vehicles are environmentally friendly and energy-saving, and have incomparable advantages over fuel vehicles, and will definitely be vigorously developed. Due to the limited capacity of transformers,...
