# OCPPLab

> OCPPLab is a cloud-based OCPP emulator and virtual charge point platform for testing Charging Station Management Systems (CPMS), running OCPP load tests, and validating OCPI roaming integrations. It supports OCPP 1.6, OCPP 2.0.1, OCPI 2.1.1, and OCPI 2.2.1, and supports high-volume virtual charger testing without a hardware lab.

Built for engineering teams at CPOs (Charge Point Operators), eMSPs (e-Mobility Service Providers), and CPMS vendors who need to validate firmware, backend, and roaming behavior against realistic charger and partner traffic. The blog covers OCPP/OCPI protocol reference, security profiles, smart charging, ISO 15118 Plug & Charge, and roaming hub integration (GIREVE, Hubject, e-clearing.net).
