Control architecture and control method of optical storage charging smart charging station based on multi-layer network

Abstract

The invention provides a multi-layer network-based control framework and control method for an optical storage charging intelligent charging station. The system includes from top to bottom an electric vehicle Internet of Vehicles cloud platform located at the dispatching layer, a charging station cluster management and control cloud platform, and distribution network dispatching. Management and control cloud platform, several charging station control center edge servers at the station control layer, various controllers at the equipment layer, state grid billing units, several AC / DC and DC / DC modules, and the station-level CAN bus of the charging station at the equipment layer as The backbone network, Unicom charging station control center edge server, each controller; equipment layer rectifier CAN bus, charging pile CAN bus, machine pile CAN bus as the secondary communication network Unicom equipment layer controllers and corresponding power electronic charging equipment. The present invention adopts the CAN bus technology, which is one of the field buses, and each controller only needs to be connected by a pair of twisted-pair wires through the network topology structure, so that the installation of the charging station control system is more flexible and convenient.

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 and charging smart charging station control architecture and control method. Background technique [0002] The electric vehicle charging station control system is a fairly complex logic control system. In general, the whole system can involve three platform layers of "cloud-pipe-end", each platform layer is composed of numerous communication devices, data Processing equipment, etc. for information interconnection, so as to realize the uploading and distribution of electric vehicle charging information at the charging station. [0003] The existing domestic electric vehicle charging stations have a relatively simple system structure, most of which are powered by the distribution network, and there are usually multiple AC and DC chargers in the station. This characteristic leads to a low utilization rate of the ch...

AI Technical Summary

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
