Question 1

What is OCPPLab and is it an OCPP simulator?

Accepted Answer

OCPPLab is a browser-based OCPP simulator and OCPI simulator for EV charging infrastructure testing. CPOs, eMSPs, and CSMS vendors run high-volume virtual charger checks without physical hardware. Coverage is OCPP 1.6 / 2.0.1 / 2.1 and OCPI 2.1.1 / 2.2.1 / 2.3.0, with reusable workflows, load testing, WebSocket debugging, and replayable protocol logs.

Question 2

Which OCPP versions does OCPPLab support?

Accepted Answer

OCPPLab covers OCPP 1.6, OCPP 2.0.1, and OCPP 2.1, plus OCPI 2.1.1, OCPI 2.2.1, and OCPI 2.3.0. OCPP paths include BootNotification, transactions, MeterValues, charging profiles, firmware, device model, and 2.1 V2G/DER sequences. OCPI paths include roaming, hubs, ChargingProfiles, and 2.3.0 Bookings. JSON schema validation is built in.

Question 3

How many virtual charge points can the OCPP emulator run at once?

Accepted Answer

A load test runs one saved OCPP workflow on up to 100 virtual chargers at once, for 10 to 600 seconds with a constant or ramping start. Each virtual charger keeps its OCPP WebSocket open, with heartbeats, status notifications, meter values, and charging sessions. Starter includes 100 charger hours a month and Pro 1,000; Enterprise has custom resource allocations.

Question 4

How does an OCPP simulator compare to physical charger testing?

Accepted Answer

Physical labs help with final hardware validation, but labs scale slowly and miss most release scenarios. As an OCPP simulator, OCPPLab adds virtual fleets, repeatable edge-case testing, vendor profile coverage, and faster protocol-level iteration before changes reach real EV chargers.

Question 5

Is there an online OCPP simulator for custom message scenarios?

Accepted Answer

Yes. As a browser-based OCPP simulator, OCPPLab includes playgrounds and reusable workflow runs for common OCPP flows. You can send message sequences, inspect responses, simulate edge cases such as network drops or timeouts, then save repeatable checks for regression review.

Question 6

Does OCPPLab integrate with my CSMS platform?

Accepted Answer

OCPPLab connects to OCPP-compliant CSMS endpoints over standard WebSocket connections. Point virtual charge points at your CSMS endpoint, inspect the routed traffic, and use the automation API for repeatable release checks.

Question 7

Is OCPPLab an OCPI simulator for 2.1.1, 2.2.1, and 2.3.0 roaming testing?

Accepted Answer

Yes. OCPPLab is an OCPI simulator that covers OCPI 2.1.1, 2.2.1, and 2.3.0 across CPO and eMSP endpoints, tokens, CDRs, tariffs, locations, commands, ChargingProfiles, HubClientInfo, and 2.3.0 Bookings. You validate roaming behavior without onboarding real partners first.

Question 8

What is the difference between OCPP and OCPI?

Accepted Answer

OCPP (Open Charge Point Protocol) covers communication between an EV charger and a Charging Station Management System (CSMS). OCPI (Open Charge Point Interface) covers roaming and interoperability between charging networks, so drivers use chargers across networks with one account. OCPP runs the charger. OCPI runs the business relationships. As both an OCPP simulator and OCPI simulator, OCPPLab tests both.

Question 9

How fast does testing start with OCPPLab?

Accepted Answer

OCPPLab runs in the cloud, so teams can start without installation, hardware procurement, or lab setup. Choose from vendor-style charger profiles, connect to your CSMS, and start testing. Plans start at $299/month.

Question 10

Is my testing data secure?

Accepted Answer

OCPPLab uses TLS, isolated tenant workspaces, and controlled data retention for test traffic and logs. Test data stays inside your tenant and can be deleted on demand. Enterprise teams can discuss private hosting or a specific region, audit needs, and security review during procurement.

Question 11

Does OCPPLab test smart charging and ISO 15118 Plug & Charge?

Accepted Answer

OCPPLab supports OCPP 2.0.1 smart-charging scenarios including SetChargingProfile and related charging-profile checks. For certificate-oriented flows, use OCPP 2.0.1 scenarios such as Get15118EVCertificate and certificate-signing paths; validate full ISO 15118 Plug & Charge behavior with your hardware and PKI stack before production.

Question 12

What does OCPPLab cost?

Accepted Answer

Starter is $299/month and includes 100 charger hours, 100 proxy routing hours, 2 CSMS connections, 500,000 OCPI requests, 1 GB-month of OCPI storage, 7-day logs, and 1 user seat. Pro is $999/month and includes 1,000 charger hours, 5,000 proxy routing hours, 4 CSMS connections, 1,000,000 OCPI requests, 10 GB-month of OCPI storage, 30-day logs, 1M AI input and 0.5M AI output tokens, and 4 user seats. Starter and Pro bill usage above those amounts: $0.10 per virtual charger hour, $0.10 per proxy charger hour, $0.10 per 1,000 OCPI requests, $0.01 per MB-month of OCPI storage, and $100 per additional user seat per month. Enterprise has custom pricing and resource allocations, a custom SLA, and private hosting or a specific region on request. SSO, SCIM, and audit logs are coming soon and are not included today.

Question 13

What reporting and analytics does OCPPLab provide?

Accepted Answer

Real-time message inspection with syntax highlighting, transaction logs with request and response correlation, and metrics for latency, throughput, and error rates. Replayable logs and shareable traces help your team review releases, share vendor evidence, and keep regression history connected to release checks.
