Embodiment Construction

[0021] An electric vehicle intelligent charging communication system includes an OCPP charging cloud management platform, a PLC communication gateway concentrator, a charging pile terminal PLC communication module, and an electric vehicle terminal PLC communication module.

[0022] Among them, the OCPP charging cloud management platform uses the TCP / IP protocol to interact with the PLC communication gateway concentrator for OCPP data protocol, and the cloud management platform can realize remote start charging, stop charging, remote reservation, charging, remote fault prompt and other management Function.

[0023] Among them, the PLC communication gateway concentrator is loaded with an embedded Linux system, runs an OCPP protocol stack, and performs data interaction with the OCPP background through various network channels such as 4G / WIFI / ETH on the upper side, and communicates and charges through the HPAV power line carrier on the lower side. The pile-end PLC communication mo...

Abstract

The invention relates to an intelligent charging communication system for an electric automobile. The system comprises a charging cloud management platform, a communication gateway concentrator, a charging pile end communication module and an electric vehicle end communication module. The charging cloud management platform performs data protocol interaction with the communication gateway concentrators by utilizing a TCP/IP protocol, the communication gateway concentrators are connected with the charging pile end communication modules through power lines, and each communication gateway concentrator can be connected with more than 256 charging pile end communication modules to construct a gateway unit of a charging station; the charging pile end communication module is connected with the electric vehicle end communication module through a power line. The system has the advantage that the problem of network wiring in medium and large electric vehicle charging stations is solved by using aPLC technology. Through software implementation, an IPV6 network layer protocol stack is built in an MCU, an ISO15118 standard communication protocol is built, and the cost of a charging system is reduced. Through the cloud management platform, multiple management functions such as remote charging starting, charging stopping, remote appointment, charging and remote fault prompting can be conveniently realized.

Description

technical field [0001] The invention relates to an electric vehicle intelligent charging communication system, which belongs to the technical field of electric vehicle communication. Background technique [0002] Electric vehicle charging management requires data interaction between the charging equipment and the management background. PLC (power line communication) power carrier communication uses the existing high-voltage power lines to transmit data through carrier waves to reduce wiring costs. [0003] HPAV (Home plug Audio Video) is a family power line communication interface standard established by the industry standardization alliance, and the communication rate of the interface is 200Mbps. Now this technical standard is widely used in power line communication, power modem, remote meter reading and other ways. [0004] HPGP (Home plug Green phy) is a communication standard that is optimized and streamlined on the basis of the HPAV standard protocol and applied to veh...
