The invention provides an information interactive system and interactive method for a charging pile and a power distribution network. The information interaction is implemented by the steps as follows: S1, the load on the outlet side of the power distribution network is divided into a charging pile load and a non-charging-pile load; S2, the output electric quantity of the power distribution network is measured by a gateway meter; S3, a BPLC (broadband power line communication) communication unit of the charging pile and the BPLC unit of the gateway meter are in real-time interaction to collect the output port electric quantity of the power distribution network; the collected data is compared with the affordable maximum load of the power distribution network in real time; and S4, a charging pile main control sends messages to an electric vehicle BMS (battery management system)according to the real-time load; and electric vehicle BMS controls the electric vehicle to decrease / increase electric power or stop the charging process. The interconnection and coordination between the charging pile and the power distribution network can be realized through the gateway meter and the control unit; therefore, the reliable and economic operation of the power distribution network is ensured; and the power distribution network can guarantee the household electricity consumption of users preferentially.
Description
technical field [0001] The present invention relates to the technical field of distribution network load coordination, and in particular to a charging pile and distribution network information interaction system and an interaction method thereof. Through the system and method, information such as charging and distribution network load and charging control can be realized interactive. Background technique [0002] With the popularization and application of electric vehicles, as an accessory equipment of electric vehicles, the number of charging piles is increasing year by year. Charging piles have gradually become an important load of the distribution network, which plays a very important role in the structure and load operation of the existing distribution network. Impact. [0003] Charging piles can be divided into DC charging piles and AC charging piles, and can be divided into fast charging and slow charging according to the charging time. The operation status of chargin...
