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,...

Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] The present invention detects the current power load situation of the community in real time, and automatically charges the electric vehicle with charging demand when the power load permits. The power load detection link is added before the ordinary charging pile, and the charging is carried out when the load allows.

[0029] The present invention provides an intelligent distribution system for electric energy of charging piles that can bring charging piles into residential quarters. It forms a charging system for electric vehicles in residential quarters together with multiple charging piles. The intelligent distribution system includes two parts, one is the detection and control part, It is called the main control unit, and the other is the part of the terminal charging pile, called the charging pile; among them, the main control unit is responsible for dete...
