The open source reference implementation of the Vehicle-2-Grid communication interface ISO 15118

RISE V2G is the Reference Implementation Supporting the Evolution of the Vehicle-2-Grid communication interface ISO 15118. The international standard ISO 15118, entitled "Road vehicles - Vehicle to grid communication interface", defines a digital IP-based communication interface between an electric vehicle (EV) and a charging station (named Electric Vehicle Supply Equipment - EVSE). It allows for a user-friendly "Plug And Charge" mechanism for authentication, authorisation, billing, and flexible load control based on a wide set of information exchanged between the EV and EVSE. A rise in the wide application of this standard is essential for reaching the goal of integrating EVs as flexible energy storage devices into a smart grid.

The RISE V2G project serves as an open source standard-compliant reference implementation and documentation. As such, the objective is to provide a test platform for interoperability testing and to offer an information resource for interested parties. The adoption of a new technology heavily depends on the interoperability of its various implementations. The more tests conducted, the more stable and reliable the developed solution will be.

RISE V2G shall evolve to cover all aspects of conductive and inductive charging and communication from the data link layer up to the application layer. However, it requires a lot of work to be done to fulfil this endeavor. Your assistance would therefore be very appreciated, be it by testing this reference implementation against your own solution - this way uncovering possible bugs or making code optimisation suggestions - or by providing an implementation for yet missing parts.

Due to a lack of time on my side and ongoing work to create a new and production-ready open-source implementation of ISO 15118 as part of Josev (Joint Operating system for Seamless EV charging), I need to discontinue the support for RISE V2G. Josev will likely be launched on GitHub by the end of 2021 under the same MIT License.
