Any make runs in one interface.
Charge points speak an open standard, which is what keeps the manufacturer replaceable.
OCPP 1.6-JOne portalOne contractTwo makes mean two portals today
The first site gets wallboxes from one manufacturer, the second from another.
Each make arrives with its own portal, its own contract, its own account.
The combined report is assembled in a spreadsheet at the end of the month.
The difference shows in six places
The same operation, two starting positions.
Tied to one manufacturer
Connected through CPIM
| Tied to one manufacturer | Connected through CPIM | |
|---|---|---|
| Portals | One per manufacturer. | One for every site. |
| Contracts | One per manufacturer. | One for the operation. |
| Pricing | Within what the portal allows. | A price per kWh per organisation, set freely. |
| Data access | Whatever export the portal offers. | Excel export at any time while your access runs. |
| Extensibility | Whatever sits on the manufacturer roadmap. | What you need goes on the roadmap. |
| Way out | A new portal, often new hardware as well. | Stations stay on the wall, the data moves with you. |
The open standard is called OCPP
Charge point and management software use it to speak one language.
Most wallboxes built in recent years already bring it with them.
CPIM uses OCPP 1.6-J, the version common in the market.
Every make sits in one list
The exit is part of the plan
What happens on the day CPIM no longer suits you.
Sessions, cards and users leave as an Excel file.
The stations carry on speaking the same standard.
Another backend takes them over with a new address and a new password.
