Intelligent charging pile Internet system of 0.4 kV power distribution network

Abstract

The invention relates to an intelligent charging pile Internet system of a 0.4 kV power distribution network. The system comprises a plurality of intelligent charging piles, an Internet of Things gateway and auxiliary equipment, and the intelligent charging piles are in communication connection through an Ethernet passive optical network; the Internet of Things gateway is in communication connection with one intelligent charging pile and is used for realizing a sensing network and a communication network; the auxiliary equipment is in communication connection with the Internet of Things gateway and used for generating a charging control signal and a charging guide signal according to the collected working state information of the intelligent charging pile, the collected charging vehicle information and the collected power grid operation information, and the charging control signal is used for controlling charging information of a charging vehicle; and the charging guide signal is usedfor guiding or assisting the electric vehicle to select the corresponding charging pile for orderly charging. The intelligent charging pile Internet system of the 0.4 kV power distribution network ishigh in bandwidth, long in communication distance, good in safety performance, not prone to interference and capable of conveniently monitoring and managing the charging piles.

Description

technical field [0001] The invention relates to the field of electric vehicle charging, in particular to an intelligent charging pile Internet system of a 0.4kV distribution network. Background technique [0002] my country's oil resources are relatively poor, and fuel and exhaust emissions are one of the main sources of air pollution in large and medium-sized cities in the future. It is undoubtedly an inevitable trend for my country's future development to vigorously develop electric vehicles. As one of the important public facilities in our daily life, electric vehicle charging devices are everywhere around us, such as on both sides of the road, in residential areas, squares and other places, providing convenience for our travel. [0003] However, the traditional electric vehicle charging and discharging strategies rarely involve the perception-communication network architecture. The existing charging infrastructure information perception-communication methods are mainly c...

Problems solved by technology

[0003] However, the traditional electric vehicle charging and discharging strategies rarely involve the perception-communication network architecture. The existing charging infrastructure information perception-communication methods are mainly centralized power line carrier, CAN bus, RS485 and other methods, but they have low bandwidth and are vulnerable to Interference, short communication distance, exposure of private information, etc.
