Brand and model
We identify the actual charger and hardware version installed.
Existing chargers and OCPP
Keep the charging installation. Add payments, access and reporting on top.
Alenta Charge is designed for owners who have already invested in EV chargers. If the chargers and current setup are compatible, payment and access features can be added without replacing working hardware.
OCPP is a strong starting point – but not the whole answer
OCPP is the standard many chargers use to communicate with a backend. But OCPP support alone does not guarantee that a specific model, firmware or existing installation can be moved or integrated directly. We therefore assess the full setup before proposing changes.
Protocol and firmware
We check relevant OCPP support and whether the firmware exposes the required functions.
Current backend
We map whether the charger is tied to an existing operator or cloud and what the vendor allows.
Charger identity
The actual OCPP Charge Point ID/deviceId must map unambiguously. Serial number or site ID is not substituted without documented mapping.
Start, stop and meter data
A successful connection requires more than online status: authentication, start, physical charging, meter data, stop and a completed session must work.
Safe transition
We do not propose changes to the existing installation before compatibility and the transition path are understood.
When the charger is compatible
Connect to the correct backend
The charger is configured for the agreed OCPP endpoint or vendor integration.
Verify identity and communication
Boot, heartbeat/status and correct mapping are verified.
Test a complete session
Start → physical charging → meter data → stop → completed session is tested before go-live.
Enable payments and user groups
QR, pricing, guest payment and approved user groups can then be activated.
What does the owner get after connection?
QR and browser card payments, different terms for user groups, session and kWh reporting, multiple locations and monthly settlements. The existing charger becomes part of Alenta Charge without embedding payment logic in the charger itself.
Vendor-specific differences are normal
Some manufacturers allow direct OCPP configuration while others use cloud platforms or require an approved integration. We therefore handle Zaptec, Easee and other vendors according to the method the manufacturer actually supports. Compatibility is not promised until verified.
Common questions about OCPP and existing chargers
Does OCPP automatically mean the charger is supported?
No. OCPP is important, but model, firmware, backend and required functions must be assessed together.
Can we test before moving every charger?
Yes. A controlled pilot with one or a few chargers is often the safest way to verify the complete charging flow.
Is online status enough?
No. A charger can be online while start, physical charging, meter data, stop or payment still fails.
Have chargers you want to keep using?
Tell us the brand, model, number of charge points and preferably which system they use today. We assess compatibility free of charge.
