A communication system from EV to EV Service Provider based on OCPP over a wireless network

The progressive market penetration of Electrical Vehicles (EVs) expected for next decades demands the development of new ICT services and tools, and Wireless Sensor Networks (WSN) are an attractive option for communication that allow fast and cost-effective deployments. Standardization is also an important issue, as communication standards for EVs are still in a state of relative immaturity, even though some initiatives for interoperability are receiving wide acceptance, as it is the case of the OCPP protocol, which is becoming a de facto standard of ever increasing use. This paper presents the development of a communication network for EV charging stations using IEEE 802.15.4 and the OCPP protocol over SOAP/TCP technology. A system demonstrator has also been built, in collaboration with a dozen partners in the frame of the “Internet of Energy (IoE)” project, as part of the European ARTEMIS Joint Technology Initiative (JTI).
