Research and Implementation of Communication between OCPP Client and Charging Station Management System

Abstract

The ability to exchange information between software and hardware systems is a key factor in the development of
charging pile systems. For a long time, the development of charging station has been seriously affected by the
standard of charging interface, a nd it has become the main obstacle to the development of charging station . In view
of the limitation of communication between charging station and backend management system, we design a
communication system between charging station and backend management s ystem based on the global open
communication protocol standard OCPP (Open Charge Point Protocol). In this paper, the framework of the charging
point client is built based on JavaScript language, so that the framework can run reliably and send specific
comm ands to the server. Then the charging station management system is built using the main tec hnologies such as
MYSQL 5.7 database, Apache maven project building and management tools, and Java development, so that the
built management system can respond to th e commands sent by the client in a fast and stable manner. The verification
of the built system shows that the two ends can interact with each other quickly and reliably and respond accurately.
The experiments show that the interaction framework can solve the difficulties arising from the communication
between charging networks today and support the interconnection between charging stations and back end systems.
The framework is capable of solving various difficulties arising from the communication between private charging
networks and aims to support the interconnection between charging stations and backend systems, providing an
effective interaction framework for true interconnection in the future.
