EV Roaming Tester

OCPI 2.2.1 Compliance Testing Tool

Comprehensive OCPI compliance testing for EV charging networks. Supports 2.1.1, 2.2, and 2.2.1. Validate endpoints, test CDR generation, and ensure CPO/eMSP interoperability.

Interactive simulator loading

This is a shareable preview of EV Roaming Tester. The full interactive simulator runs in your browser with JavaScript enabled.

Use it to validate OCPI integrations, explore message flows, and reproduce roaming issues between CPO and eMSP systems without installing anything.

Key capabilities

  • OCPI 2.2.1 protocol compliance and validation workflows
  • Request/response inspection for endpoints and payloads
  • Token, session, and CDR troubleshooting utilities
  • Interoperability checks for roaming integrations
  • Repeatable test scenarios without local setup

Common workflows

Teams usually begin by defining one test objective and one expected outcome, then running a controlled scenario and inspecting sequence behavior. This makes triage faster and avoids noisy debugging sessions.

  • Validate OCPI endpoints by sending sample requests and inspecting responses for protocol correctness.
  • Reproduce a roaming issue by simulating a full session lifecycle and comparing message order and payloads.
  • Review message flows to align engineering and product teams on expected CPO ↔ eMSP interactions.
  • Capture logs and share a single URL to discuss a specific scenario with teammates.
