WWCP Core

The World Wide Charging Protocol Suite is a suite of protocols that provides a unified architecture, designed to link all stakeholders in electric mobility and energy networks through scalable, secure and semantic Internet protocols.

Unlike traditional e-mobility protocols, the WWCP Suite prioritizes IT security, privacy, transparency, metrology, and semantics in an extensively connected open environment. Therefore the suite also emphasizes interoperability with existing protocols and both backward and forward compatibility within its own framework.

This repository lays down the bedrock concepts, entities, and data structures, and provides a reference implementation of virtual components like Electric Vehicle Supply Equipment (EVSEs), charging stations, charging pools, charging station operators, e-mobility service providers, roaming networks, national access points and more. These components are designed to facilitate continuous integration testing and penetration testing within e-mobility roaming networks.

Related Projects

Serveral project make use of this core library:

• WWCP OICP defines a mapping between WWCP and the Open InterCharge Protocol v2.3 as defined by Hubject GmbH and thus allows you to enable EMP and CPO roaming.
• WWCP OCPI defines a mapping between WWCP and the Open Charge Point Interface v2.1.1 and v2.2 and thus allows you to enable EMP and CPO roaming via direct connections betwewen those entities.
• WWCP OCPP defines a mapping between WWCP and the Open Charge Point Protocol v1.6 and v2.0.1 and thus allows you to attach OCPP charging stations.
• WWCP ISO15118 defines a mapping between WWCP and ISO/IEC 15118 and thus allows you to communicate between electric vehicles and charging stations.

The following project are compatible solutions:

• ChargySharp The C# reference implementation of the Chargy e-mobility transparency software.
• Chargy Desktop App An e-mobility transparency software for Windows, Mac OS X and Linux (based on the Electron framework).
• Chargy Mobile App An e-mobility transparency software for iOS and Android (based on Apache Cordova).

The following projects are no longer in active devlopment, but left for educational purposes

• WWCP OCHP defines a mapping between WWCP and the Open Clearing House Protocol and thus allows you to enable EMP and CPO roaming.
• WWCP OIOI defines a mapping between WWCP and the OIOI Protocol as defined by PlugSurfing and thus allows you to enable EMP and CPO roaming.
• WWCP eMIP defines a mapping between WWCP and the eMobility Protocol Inter-Operation as defined by Gireve and thus allows you to enable EMP and CPO roaming.
