Open Charge Point Protocol
The goal of the Open Charge Point Protocol (OCPP) is to provide a uniform solution for communication methods between charge points and central systems. This protocol makes it possible to connect any central system to any charging point, regardless of provider. Uniform standards prevent various coordination problems and are therefore an advantage for the entire electric vehicle market.

Open smart charging protocol
The basic function of the Open Smart Charging Protocol (OSCP) is to transfer physical network capacity from the DSO (or station owner) to the charge point operator’s back office. The protocol can be used to communicate a 24-hour forecast of locally available capacity to Charge Spot operators. Service providers will adjust EV charging profiles within available capacity.
