Product Details
SECC / EVCC Two-in-one Evaluation Board
C# full-stack implementation of ISO 15118 V2G charging communication, from SLAC pairing to EXI application messages, covering DIN70121 / ISO15118-2 / ISO15118-20 / GB/T 27930.
Two-in-one Evaluation Board
One board supports both SECC charging-station-side and EVCC vehicle-side roles, enabling full V2G protocol integration testing on a single board.
- SECC: Supply Equipment Communication Controller
- EVCC: Electric Vehicle Communication Controller
- On-board HomePlug Green PHY PLC chip with complete SLAC physical-layer pairing.
- Ethernet interface supports SDP discovery and TCP/TLS connection establishment.
- Based on .NET NativeAOT: develop on Windows and deploy to ARM32 boards.
Bench Testing
Real hardware running the full protocol stack — not just a demo.
▲ Full ISO 15118 / GB/T 27930 integration validation in an actual bench environment
Protocol Coverage
Three international standards plus the Chinese national standard, all supported by one codebase.
DIN 70121
German industrial standard for early DC fast chargers, covering the full charging session flow.
ISO 15118-2
Mainstream AC/DC charging communication standard with payment options and service discovery.
ISO 15118-20
Latest standard supporting AC/DC/WPT, scheduling exchange and metering confirmation.
GB/T 27930
Chinese national charging communication standard with EVCC-side integration.
System Architecture
End-to-end C# implementation from application entry to physical layer.
HomePlugInteractor encapsulates PLC packet IO and the SLAC flow with Linux/ARM and Windows/x64 backends.
Core Technical Highlights
Real engineering capabilities extracted from production code.
π Security and Certificates
- Complete V2G PKI certificate system.
- Supports no-transport-layer-security and TLS secured modes.
- TLS handshake with production-grade security foundations.
- Certificate-chain validation aligned with ISO 15118 PKI architecture.
π‘ Physical Layer
- Full HomePlug Green PHY SLAC attenuation matching process.
- Supports CmSlacParameter, CmAttenChar, CmSlacMatch and related message sequences.
- SDP service discovery and V2GTP transport encapsulation.
β‘ Application Layer
- EXI efficient binary serialization with pre-initialized grammar cache.
- ISO 15118-20 message dispatch using C# pattern matching switch expressions.
- Supports AC, DC and WPT energy transfer modes.
- MeteringConfirmation and ScheduleExchange flows implemented.
π₯οΈ Developer Experience
- Windows x64 debugging and ARM32 board deployment.
- NLog observability for SLAC, SDP, TLS and session flows.
- Differential update support for lower firmware update cost.
- One codebase maintains both SECC and EVCC logic.
