Optical storage and charging intelligent charging station control architecture and control method based on multi-layer network

Abstract

The invention provides an optical storage and charging intelligent charging station control architecture and control method based on a multi-layer network, and the system comprises an electric vehicle networking cloud platform, a charging station cluster management and control cloud platform, a distribution network scheduling management and control cloud platform, a plurality of charging station control center edge servers located in a station control layer, controllers arranged at an equipment layer, a state grid billing unit and a plurality of AC / DC and DC / DC modules, wherein the parts are arranged from top to bottom; a station-level CAN bus of a charging station of the equipment layer serves as a backbone network and is communicated with the charging station control center edge server and the controllers; and an equipment layer rectification CAN bus, a charging pile CAN bus and a machine pile CAN bus are used as secondary communication networks to communicate each controller of the equipment layer with corresponding power electronic charging equipment. According to the invention, the CAN bus technology which is one of field buses is adopted, all the controllers can be connected through a network topology structure by only needing a pair of twisted pairs, and the charging station control system is more flexible and convenient to install.

Description

technical field [0001] The invention relates to the field of electric vehicle charging station control, in particular to a multi-layer network-based optical storage charging smart charging station control framework and control method. Background technique [0002] The electric vehicle charging station control system is a rather complicated logic control system. In general, the whole system can involve three platform layers of "cloud-pipe-end", each platform layer is composed of many communication devices, data Processing equipment and other information interconnection, so as to realize the upload and release of electric vehicle charging information at the charging station. [0003] The existing domestic electric vehicle charging station system structure is relatively simple, and most of them adopt the power distribution network. There are usually multiple AC-DC chargers in the station. Because the power of a single AC-DC charger is large, the single charging time This featu...

Problems solved by technology

[0003] The existing domestic electric vehicle charging station system structure is relatively simple, and most of them adopt the power distribution network. There are usually multiple AC and DC chargers in the station. Because the power of a single AC and DC charger is large, the single charging time Short, this feature leads to low utilization rate of the charging station at night when the grid load is low, and during the daytime grid load peak period, if there are a large number of electric vehicles that need fast charging at the same time, the high-power charging demand will bring power to the grid. The short-term load shock will further strengthen the fluctuation of the power grid
