OCPP

What is OCPP

Terminology: Interoperability or Roaming

• Roaming, for end user • Authorization • Billing

• Interoperability, for network operators • Multi-vendor networks (best equipment for specific situations) • Choice of service (best fit for needs) • Quality of service (switching without replacing hardware)

OCPP: background

• E-Laad Foundation: Founded by the Dutch utilities to • implement national charging network • study effects of charging/driver behavior on the grid • seek international cooperation

• An open interoperable system, no vendor lock-in • increased flexibility • increased innovation • increased competition • decrease total costs

OCPP principles

• The protocol description is published and can be obtained free of charge

• there are no constraints on the re-use of the standard

• the IP rights to the standard are vested in a not-for-profit organisation, which operates a completely free access policy

• Further development done by consensus in a open and transparent process, where anyone can participate in the development process.

Public network example 1: ESB

• One national utility • one network • Multiple charging station vendors

• Roaming: Northern Ireland • Independent choice station • Same back office

Public network example 2: E-Laad

• 8 utilities working together • One national network • Multiple charge point manufacturers

• National roaming • E-Laad network + local/private networks • Authorization • Charge Detail Records

• International roaming: Germany and Belgium

Private network example: The Hague

• 300 stations

• Main contractor: Alfen

• Sub contractors: BAM, The New Motion

• Local network, national roaming

OCPP in context: Interfaces

E-Laad

• Organization type: Foundation

• Founders: Tennet, Enexis, Liander, Delta, Rendo, Westland Infra, Endinet, Cogas

• Mission: Implement charging network of 10.000 by end 2013

• Current network: +/- 2000 charge points

Organization

Steering group: • Vision and roadmap • Define work group packages • Consists of main stakeholders • Budget holder • Approve the standard/releases • Handles possible issues

Work group: • Execute work package • Define changes/additions in

detail • Advise steering group • Consist of OCPP specialists

Executive organisation (facilitator): • Organizer of steering group meetings (and prepare meetings) • Independently leading the work group • Writing down the standard and changes (made by the work group) • Executing the helpdesk function • Making a small annual plan • 2 part-time persons from a independent,- or branch organisation

Development process • Steering group (SG) makes inventory of change requests

• SG groups change requests into topics/work group (WG) assignments

• SG publishes topics, time and location for workshop • Interested parties register for active participation, preferably with topic(s) of interest • During workshop final WG’s are formed and assignments carried out, resulting in:

• Concrete solutions for items where consensus has been reached • Hand-back of non-consensus items to SG

• SG evaluates and creates new assignment/WG for non-consensus items

Guidelines for the development process

• Evolutionary: keep it pragmatic: start simple, grow as needed

• Interoperable: Only generic functionality, nothing vendor-specific

• Up-to-date: Keeping track of technological improvements and incorporate them in the protocol

• Transparent: Everything we do, decide and create should be visible and understandable to all

History • October 2009: Start E-Laad foundation • Initial charging stations with proprietary protocol • Definition of open protocol (OCPP) • October 2010: Release OCPP 1.2 • August 2011: First international workshop to define OCPP organisation • June 2012: Release OCPP 1.5 • September 2012: Kick-Off OCPP 2.0 - • April 2013: 2.0 Release candidate 1 • July 2013: 2.0 Final?

OCPPforum.net • Started September 2011 as OCPP.nl • Goals:

• Central point of information • Central location for tools • Forum to ask questions/find anwers

• Membership • 200 members by januari 2012 (kick-off workshop 1.5) • 500 members by September 2012 (kick-off workshop 2.0) • Currently 800+ • Members: See “OCPP in Context: involved”
