WWCP ISO/IEC 15118-20

This software will allow the communication between World Wide Charging Protocol (WWCP) entities and entities implementing ISO/IEC 15118-20 and ISO/IEC 15118-8 for wireless communication. The focus of this protocol are the communication aspects between an electric vehicle and an e-mobility charging station.

Implementation details

In order to make development and debugging 1024 times easier, this ISO/IEC 15118 implementation comes with additional JSON (de-)serialization. As, as far as we know, no other project has yet defined a JSON schemata for ISO/IEC 15118, we defined our own, which adopts some JSON-LD concepts like the "@context" property.

Differences to the official protocol specification

The following desribes differences of this implementation to the official protocol specification. Most changes are intended to simplify the daily operations business, high availability or to support additional concepts/methods like European General Data Protection Regulation (GDPR) and the German Calibration Law (Eichrecht).

• Class and data type names do not strictly reflex the names defined within the XML schemata.
  • E.g. all collection property name have plural names like "authentication elements" instead of "authentication element".
  • Request and response classes do not use the short "Req" or "Res" words.
  • The name of ENUM classes always have plural names.
  • Helper classes for collections are avoided and IEnumerable<...> is used instead.
