The C2EU device is a charging station that offers a range of functionalities for electric vehicle charging, along with features for software updates, connectivity, and local authentication management. This service manual focuses on the software aspects of the device, providing detailed instructions for its maintenance and configuration.
The C2EU primarily functions as an electric vehicle charging station. Its core operation involves managing the charging process, which includes communication with a backend system, handling local authentication for users, and maintaining operational logs. The device supports the OCPP (Open Charge Point Protocol) for communication with a central management system, allowing for remote control, monitoring, and data exchange. It also incorporates local authentication capabilities, enabling users to initiate charging sessions using RFID cards or other authorized methods without necessarily relying on a constant backend connection. The device's firmware and driver software are designed to be upgradable, ensuring that the charging station can adapt to new features, security updates, and protocol enhancements over time.
The C2EU offers several usage features that enhance its operational flexibility and user experience. For connectivity, the device supports both wired LAN and cellular (SIM card) connections, allowing it to communicate with the OCPP backend. Users can configure APN settings for cellular connectivity, ensuring proper network access. The device's interface allows for the display of current firmware versions and operational status, which can be accessed by pressing the home button for a few seconds. This provides quick diagnostic information.
For charging operations, the C2EU can be configured to operate under specific communication protocols, such as OCPP, and requires the input of URL, model, and vendor information for backend integration. This setup is performed through a graphical interface accessible via a wired mouse connected to the charging station. The device also supports a local whitelist for authentication, which means that authorized users can be added to a local database on the charger itself. This feature is particularly useful in scenarios where continuous internet connectivity might be unreliable or for private charging installations where a backend system is not always necessary for authentication. Conversely, a blacklist can also be managed locally to prevent unauthorized access.
The C2EU is designed with several maintenance features that facilitate its upkeep, troubleshooting, and software management.
