CTEK chargers on Flowion.

3 models catalogued, speaking OCPP 1.6J. These connect straight to Flowion: you set the CSMS URL on the device and it speaks OCPP to us with nothing in between.

Every CTEK model below is set up the same way, so the choice between them does not change the connection work.

OCPP direct

The charging station opens its own WebSocket to Flowion. You configure the CSMS URL on the device and it speaks OCPP to us with nothing in between.

Provisioning

How you point CTEK at a CSMS

Compatibility is a protocol question and it is usually the easy half. Changing the CSMS URL is the part that takes an afternoon, and it differs by manufacturer far more than the protocol does.

  • Vendor portal

    Set in the manufacturer's cloud portal. You cannot type a URL into the box; the vendor pushes the setting to it.

Provenance

Where this came from

Researched 2026-08-12 from the sources below. Vendors ship firmware faster than anyone updates a table like this, so confirm the exact SKU before you buy a pallet of them — and see how to read these labels for what each one claims.

Connect the CTEK you already own.

No rip and replace. Point your existing chargers at your organization's URL — and when the hardware isn't in the room, the simulator is.
