An Empirical Analysis of the Openness Dimension of OCPP Standard

Open Charge Point Protocol (OCPP) is a widely used open communication protocol between a charging station and its managing network system. The central promising idea of the OCPP is that it is an open standard, which provides a standardized communication language with the flexibility of giving charging station owners right to switch network providers at their own will. This paper investigates the open standard concept with various aspects in the context of OCPP. By investigating the openness of OCPP across multiple dimensions, this paper represents, to our knowledge, the first attempt to unbox what an OCPP looks from an open standard perspective within the electric vehicle charging infrastructure.
