Simulate the EV charger profiles your team actually deploys.
Vendor-style profiles with realistic connector layouts, current types, supported kWh, and OCPP behavior for CPMS testing.
Protocols & standards
OCPP and OCPI in the OCPPLab workspace
The workspace covers OCPP 1.6 / 2.0.1 / 2.1 and OCPI 2.1.1 / 2.2.1 / 2.3.0. EEBUS and Modbus are adjacent energy and industrial standards, not product modules.
OCPP
Shipped in the workspace
The Open Charge Point Protocol is an application protocol for communication between electric vehicle charging stations and a central management system.
OCPI
Shipped in the workspace
The Open Charge Point Interface is a protocol that connects charge point operators and e-mobility service providers, enabling EV roaming, location and tariff data, and the exchange of charging sessions and billing records between networks.
EEBUS
Adjacent standard — not a product module
EEBUS is a protocol suite for the Internet of Things that aims to standardize the interface between electrical consumers, producers, storages and (logical) managing entities.
Modbus
Adjacent standard — not a product module
Modbus is a data communications protocol. It is a de facto standard communication protocol and widely used to connect industrial electronic devices.
Built for every layer of the charging stack
Virtual chargers, protocol routing, roaming validation, and monitoring probes. One workspace, no hardware.
OCPPLab SDK
Deploy virtual chargers, run a roaming backend, and stress-test your system at scale in minutes.
Virtual hardware profiles
Simulate any charger brand. Test your software across OCPP 1.6 / 2.0.1 / 2.1 without physical hardware.
“Hardware labs still matter, but they should confirm behavior you already rehearsed. Make the first integration failure happen in a browser, not during a field rollout.”
Inside the app
Workspace areas for chargers, proxy, roaming, and simulation.
Charging, virtual charger, OCPP proxy, roaming, observability, and the operator assistant. The OCPP simulator still lives here as virtual charger — not as the only product story.
Virtual charger
Fleet, sites, logs, workflows, and playgrounds for hardware-free OCPP simulation.
OCPP proxy
Backends, tokens, routes, and a message log for charger traffic you already route.
Roaming
Partners, OCPI catalog, sync, commands, and charging profiles in one workspace.
Observability
Health hub and webhook callbacks or logs for the protocol paths you run.
Operator assistant
Eve chat on the home screen for questions about charging data. Session required.
Protocol coverage
Version support for OCPP and OCPI
Cover OCPP 1.6 / 2.0.1 / 2.1 and OCPI 2.1.1 / 2.2.1 / 2.3.0 in one workspace. From virtual chargers and smart charging to OCPI roaming, keep charger behavior, roaming flows, and regression coverage in one place.
Release workflow
Put OCPPLab before the field trial.
Hardware labs and partner sandboxes are still important, but they are slow places to discover basic integration bugs. Use the OCPPLab simulator earlier in the release cycle for CSMS testing and to validate the behavior your team controls.
Reproduce field bugs
Replay the charger, authorization, transaction, or roaming path that failed without waiting for the same hardware state.
Onboard chargers
Create model-like EV charger profiles, connect them to your CSMS, and verify setup before devices arrive on site.
Validate roaming partners
Check OCPI data and commands before a real CPO, eMSP, hub, or network partner is on the critical path.
Run release checks
Turn repeated manual checks into workflow runs with logs your team can inspect after every product change.
