OCPP (Open Charge Point Protocol) is an open communication standard. OCPP controls the communication between a charging station and a back-end system of OCPP service provider, focusing on monitoring and billing.
OCPP can easier to create a large-scale, visible charging station network that uses a range of different charging stations since there is a requirement for only one operating system. It's similar to cell phones and cell phone networks.
Contracting with an OCPP service provider open a wide range of services for station owner as:
- charging service is available for any public electric car owners
- internal billing of energy consumption in semi-public (e.g rental office building) charging networks
- managing charging availability for users
