Payment & Operation

In order to be able to invoice charging processes in accordance with calibration law, chargeBIG relies on its own backend. The user‘s smartphone is used to display the progress of the charging meter. In the backend, signifi cantly more data than in the OCPP standard (Open Charge Point Protocol) will be transmitted (for example temperature data, information on overvoltage protection, data on integration into the fi re alarm system etc.). The backend creates the invoice receipt for the users, transmits the payment data to the payment provider, enables a reporting of the charging data and realizes the interface to the German Bundesnetzagentur (BNetzA).

The chargeBIG backend can be connected to other backends via appropriate standards. Thus eRoaming can be offered for chargeBIG charging points.
