CSMS testing without hardware
The problem
Building a CSMS means testing against dozens of charger vendors, each with their own OCPP implementation quirks. A physical test lab is costly to set up, takes weeks to configure, and covers only a handful of scenarios at a time.
- Every physical charger is a hardware purchase
- Lab setup can take weeks for each vendor
- A bench tests only a few charge points at once
- No way to simulate peak load or failure scenarios
- Bug fixes require physical access to test hardware
The solution
OCPPLab simulates vendor-style charge point behavior. Run virtual charger checks, test important edge cases, and make QA workflows repeatable.
- Vendor-style device profiles (ABB, EVBox, Wallbox, Alfen, etc.)
- Run load tests with up to 100 virtual chargers at once
- Simulate firmware updates, network failures, and concurrent sessions
- Reusable workflows cover common OCPP requirements
- Run release checks with automation API access
What you can test
BootNotification handling
Validate how your CSMS registers and configures new charge points across all vendor types.
Transaction management
Test StartTransaction, StopTransaction, and MeterValues flows with realistic charging patterns.
Smart charging (OCPP 2.0.1)
Validate charging profiles, power limits, and grid integration with SetChargingProfile.
Firmware management
Test firmware update workflows including download, install, and rollback scenarios.
Authorization
Validate RFID, remote start, and certificate-oriented OCPP 2.0.1 authorization paths.
Error recovery
Simulate network drops, timeout scenarios, and charge point reboot sequences.
What is CSMS Testing?
CSMS (Charging Station Management System) testing validates that your charging platform correctly handles OCPP communication with charge points at scale. That means testing BootNotification registration, transactions, meter values, smart charging profiles, firmware updates, and error recovery. Without virtual testing tools like OCPPLab, teams rely on physical hardware labs that are costly to build and test only a handful of charge points at once. OCPPLab lets teams simulate virtual charge points across vendor-style profiles. Run repeatable workflow suites and add checks to release pipelines.
