Overview:

This Raspberry Pi HAT is a versatile communication adapter integrating an IEC 61851 Control Pilot (CP) interface with a Powerline Communication (PLC) modem. It offers creating a platform for learning, developing, and testing EV charging systems. It supports global standards including ISO 15118 and DIN 70121. The module features hardware jumpers and software-reconfigurable PLC firmware, allowing switching between EV and EVSE modes. It integrates with the open-source EVerest project to provide a platform for community-driven charging development.

Applications:

• Protocol Mastery: Hand-on learning and familiarization with global EV charging standards and communication protocols.
• Rapid Simulation: Quickly simulate EV or EVSE counterparts for Software-in-the-Loop and Hardware-in-the-Loop testing using open source.
• Deep-Dive Research: Enable in-depth experimentation and analysis of charging communication.
• Future-Ready V2X: Implement and test custom extensions for Vehicle-to-Everything (V2X) and grid integration.
• Security Validation: Simplify penetration testing to identify and patch vulnerabilities.
• Agile Prototyping: Drastically reduce time-to-market for new EV or EVSE software implementations by easily testing open-source projects (EVerest)
