Everything SimItNow can do, and which parts of OCPP 1.6, 2.0.1 and 2.1 it supports.
From a single connector to hundreds of concurrent stations, plus a hosted CSMS chargepoints can dial into, SimItNow covers what your test plan needs.
Before a station is created, SimItNow opens a real OCPP handshake against your CSMS and tells you in plain language what went wrong (credentials refused, wrong path, unreachable host) instead of leaving you with a station that silently never connects.
Simulate multiple EVSEs and virtual chargepoints per station. Configure any topology your CSMS expects, from single-port units to large multi-port sites.
Virtual EVs with live battery tracking. Watch the charge level rise as your CSMS manages the session, just like a real vehicle plugged in.
Meter readings flow to your CSMS on schedule, indistinguishable from physical hardware. Your billing and reporting features get real data to work with.
Supports both AC (up to 11 kW) and DC fast-charging (up to 90 kW) modes with dynamic power distribution and charging profile management.
Full programmatic control over every simulator lifecycle. Integrate directly with your test harness, CI pipeline, or load-testing scripts.
Point SimItNow at a staging environment or your CSMS/CPMS backend and script OCPP conformance testing and regression suites into every pipeline run, with no physical charge point emulator to rack, cable, or maintain.
Simulate disconnects, reconnects, and error states on demand. Verify your CSMS handles degraded conditions safely and recovers correctly.
Run time-dependent scenarios (session timeouts, reservation expiry, scheduled charging) instantly, without waiting for real time to pass.
Spin up hundreds of concurrent charging stations and EVs simultaneously. SimItNow's cloud infrastructure handles the scale, with no setup or provisioning required on your end.
Each station reconnects automatically with random jitter on connection loss, mirroring real-world charger behaviour your CSMS must handle.
Connect to CSMS endpoints that require Basic Auth or TLS. Pass a security object at create time, and SimItNow adds the Authorization header and SSL context automatically, with no changes to your OCPP logic.
Simulate OCPP 2.0.1 and 2.1 charging stations alongside existing 1.6 stations. Full transaction lifecycle, smart charging profiles, and device model support: connect any 2.0.1 or 2.1 capable CSMS today.
Every account gets its own CSMS instance: the mirror image of simulating a station. A real or simulated chargepoint implementation dials in over wss:// using the address generated for your account, with no registration and no password, and you validate its client-side OCPP behavior (1.6, 2.0.1 or 2.1) against a real Central System. The number of chargepoints connected at once matches your charging station allowance, and private mode with per-chargepoint passwords is available through the v2 API.
protocol: "ocpp2.1"Every operation is a REST call. The API docs have the full endpoint reference, with examples.
Create a free account, generate an API key and connect a virtual station to your CSMS. You do not need a credit card or any installation.
