OCPP (Open Charge Point Protocol)
An open communication protocol between a charging station and central management software, used for remote control, billing and monitoring.
Technical level:Advanced
Through OCPP the charger connects over the internet to a management platform, which can start and stop charging sessions, authorise users, record the energy of each session and limit the power. The versions you will usually come across are 1.6J and 2.0.1.
Because the protocol is open, a station with OCPP does not tie you to one provider. In an apartment building, a hotel or a company fleet you can later switch platforms without replacing the charger.
When planning the installation, provide a stable connection at the mounting point, with a network cable or good mobile signal. A charger that frequently loses its connection causes problems with user authorisation and billing.
