How to establish connection between commercial charging station and operation management platform?

Before commercial wall charging station is launched on the market, customers need to select and connect a suitable platform to manage the operation. Charging stations and operating platforms are connected directly via TCP/IP protocol and use CS (client/server) mode for communication.

The charging station acts as a client, operates the platform as a server, maintaining a long-term connection between the two sides. Sending information from the client to the server is defined as uplink, and sending information from the server to the server is defined as downlink.

Previously, we introduced OCPP1.6, an important version of OCPP that implements the core communication management and monitoring functions of charging stations. Connecting charging stations that support the OCPP1.6 protocol to the operation management platform involves several key steps:

Understanding the OCPP protocol:First, you need to be familiar with the basic concepts and architecture of the OCPP protocol. There are several versions of the OCPP protocol, such as OCPP1.5, OCPP1.6, and OCPP2.0. Choose the version that suits your needs and read its specifications in detail.

Select a method of communication:OCPP supports multiple communication methods, such as WebSocket, SOAP, and JSON. Choose the appropriate communication method according to your needs and device capabilities.

Development of software for charging stations:development of software for charging station devices in accordance with the OCPP protocol specifications. This includes the implementation of various message types, data models and business logic defined in the OCPP protocol.

CSMS Integration:To enable communication between charging stations and charging station management systems, the charging station software must be integrated with the CSMS. This typically involves implementing the API provided by the CSMS and enabling two-way communication between the charging stations and the CSMS.

Testing and debugging:Before actual deployment, the charging station software and CSMS integration must be fully tested and debugged. This includes functional testing, performance testing and security testing.

Deployment and monitoring:Deploying tested and debugged charging station software to a real device and ensuring it communicates correctly with the CSMS.

The above steps describe the basic processes of connecting the OCPP1.6 protocol supported by charging stations to the operation management platform. For specific implementation, please refer to the relevant white papers and manuals to ensure a smooth connection process.
