Design decision
A charging station management system coordinates charging stations, sessions and operational records. An OCPP version label is only the starting point: agree supported profiles, security settings, firmware versions and tested message flows at both ends. OCPP communication does not by itself provide payment acquiring, roaming contracts or tax-compliant invoicing. Specify the operational workflow from authorization to settlement and reconciliation.
When this approach fits · Limits and alternatives
A managed backend can fit multi-site operation with clear support ownership. It is less suitable when exports, migration rights or offline behavior are undefined. Test duplicate and delayed transaction events, lost connectivity, remote diagnostics, certificate renewal and access revocation. Request a data-flow diagram, processor responsibilities, retention settings, export format and exit plan. Verify any claimed certification against the exact product and version, without implying that this guide certifies it.
Procurement checks
- Test the exact OCPP 1.6J/2.0.1/2.1 interoperability profile
- Clarify data controller, hosting, cybersecurity and operator responsibility
- Verify payment provider and support terms for the target market
Evidence to request
Define the installation country, supply, arrival and departure times, energy per session and operating constraints. Ask for an electrical design, exact configuration, test evidence and acceptance plan. Include support responsibilities and data ownership in the written scope.
