As the name indicates, the OCPP is open source, patent- and royalty-free with no cost or licensing barriers for adoption.

With the 2.0 version, developers should be able to easier implement all of the important features they need.

OCPP 2.0 added/improved functionalities

1) Device Management:
Features to get and set configurations and also to monitor a Charging Station. This is a long-awaited feature, especially welcomed by Charging Station Operators who manage complex multi-vendor (DC fast) charging stations.

2) Improved Transaction handling:
Especially welcomed by Charging Station Operators who manage large numbers of charging stations and transactions.

3) Added Security:
The addition of secure firmware updates, security logging and event notification and security profiles for authentication (key management for client-side certificates) and secure communication (TLS).

4) Added Smart Charging functionalities:
For topologies with an Energy Management System (EMS), a local controller and for integrated smart charging of the EV, charging station and Charging Station Management System.

5) Support for 15118:
Regarding plug-and-charge and smart charging requirements from the EV.

6) Display and messaging support:
To provide the EV driver with information on the display, for instance regarding rates and tariffs.

7) And many additional improvements requested by the EV charging community.

Open Charge Alliance launches OCPP 2.0

A new open standard protocol for charging stations worldwide

ARNHEM, The Netherlands, April 17, 2018 /PRNewswire/ — On April 11th the newest version of the Open Charge Point Protocol (OCPP) became available for all charging stations manufacturers and operators. The Open Charge Alliance (OCA), the international non-profit organization advancing open standards for electric vehicle charging infrastructure, has updated and expanded their protocols with new features regarding security, smart charging and improved transaction handling. OCPP is open source, patent- and royalty-free with no cost or licensing barriers for adoption. The ultimate goal is to have a global standard for all charging stations that provides easy access for EV-drivers.
OCPP is considered the de-facto standard for charging infrastructure interoperability among charging equipment manufacturers, software and systems providers, charging network operators and research organizations. The OCA hosts technical, compliance and marketing workgroups that advance the protocol. The development of the OCPP is accelerating adoption of electric vehicles as open standards among charging stations increase ease of both charging and billing.

Feedback from OCPP community

OCPP 2.0 is the follow up to the October 2015 version OCPP 1.6. It has a lot of new and improved features regarding device management, transaction handling, security, smart charging functionalities, 15118 support, support for display and messaging and many additional improvements requested by the EV charging community. During the development and review period of the draft version of OCPP 2.0, the OCA consulted their own membership – more than 100 active participants from 27 countries on five continents – as well as the full community of thousands of OCPP users to gather feedback and user experiences in an open public review.

Smart Charging, enhanced security and improved customer experience

With an increasing demand for fully electric cars worldwide, securing charging station transactions and balancing the electricity grid to prevent capacity problems are key elements for the future. OCPP 2.0 has added secure firmware updates, security logging and event notification and security profiles for authentication (key management for client-side certificates) and secure communication (TLS). To relieve the pressure on the grid, OCPP 2.0 has added Smart Charging functionalities: for topologies with an Energy Management System (EMS), a local controller and for integrated smart charging of the EV, charging station and Charging Station Management System.

Especially welcomed by Charging Station Operators who manage large numbers of charging stations and transactions, the new version of OCPP has improved the transaction handling. It also contains new features to get and set configurations to monitor a Charging Station. This is a long-awaited feature by Charging Station Operators who manage complex multi-vendor (DC fast) charging stations. OCPP2.0 offers the option to support plug and charge for electric vehicles supporting the ISO 15118 protocol.

OCPP 2.0 is available now for download. All documentation can be found om www.openchargealliance.org.

The devil is in the details here I’m sure. It would be nice if they would have a technical writer, or at least someone who can speak plainly, and succinctly clearly describe what is being proposed, without generalizations.

This is very good. The J-1772 is already standard and now the software can give the same options and ability. That is good for everyone.

I’d like to see all stations nationwide also all bill by the kWh.
Always show you how fast (in Kw) you are charging.
Also always show you how much you pay.

Many like Blink don’t give you any idea how much power you are getting, slow ,fast ???
Charge Point and most others show the POWER so you know what to expect.

Yeah I know… Blink stations don’t tell you what rate you are charging at. The new ultra fast charging stations that Electrify America is deploying do show a very nice display with the percentage you started at, how long til 80%, and the kWs you are pulling. See a picture in the article I wrote about us charging at the first Electrify America station three weeks ago: https://insideevs.com/insideevs-visits-first-ultra-fast-ccs-station-in-u-s/

About billing by the kWh, personally I actually support per minute billing over per kWh billing, but both are fine. There are many good reasons to bill by the minute.

I can’t tell if this feature is included. But I’d like to see the vehicle VIN transmitted to the station. That way I could setup an account with a charging company and all I’d need to do is plug in my car and it would automatically detect that I have an account with them and bill be accordingly.

That’s what point #5 does. It’s called Plug & Charge. Electrify America is implementing this on their stations this year, and any new EVs that come out that support it will be able to do like a Tesla does at a Supercharger now… just plug it in and walk away.
