Introduction to
OCA and OCPP

Open Charge Alliance © 2014-2024

The Open Charge Alliance (OCA) is the industry
alliance governing OCPP
➢ Our goal is to help the EV charging industry accelerate➢ A nonprofit foundation under Dutch law➢ Founded in 2014

➢ Currently 369 members➢ OCPP is continoulsy developed following the need of thegrowing industry and incorporating field experience➢ Open, patent and royalty free with no cost or licensing
barriers➢ OCPP is a trademark and is protected by copyright license

OCA is continuously improving the Certification Program➢ Efforts to reduce the Certification costs for the industry➢

Discounted Certification fee when vendors certify multiple products per year➢

New OCTT for faster Certification testing of OCPP➢

OCTT support for a Vendor Declaration of Conformance➢OCTT support for an API so that vendors can integrate OCTT into their software development (CI/CD)➢We are exploring adding a ‘Product Family list’ to the certificate for derivative products

Update OCPP as an IEC standard•

OCA & IEC intend to submit OCPP for approval as anInternational Standard using the IEC Fast Track Procedure.

•If the IEC TC69 P member committees approve of theproposal, OCPP will be published ‘as-is’ as an InternationalStandard.

•

OCA will remain the maintainer of OCPP and intends tosubmit all future versions (e.g. OCPP2.0.1 ed4 (including
future errata), OCPP2.1 and OCPP3.0) to IEC (TC69) for ‘asis’ approval as an IEC International Standard following theFast Track procedure.

Open Charge Alliance © 2014-2024

Two steps
Step 1
OCA is accepted
as Liaison A
partner of IEC

Step 2
OCPP is accepted
as-is as an IECInternational
Standard underthe conditions ofOCA

Voting by IEC TC69 Participating National
Committees•

September – November 2023•

75% yes!

•OCA has proposed to include IEC in thefuture development of OCPP under OCA•

We are finalizing the discussing with IEC
management regarding the proper
procedure•

If the procedure is approved, TC69 National
Committees can vote again

OCPP2.lite

Open Charge Alliance © 2014-2024

Why OCPP2.lite?
We are adding a lot of features to OCPP for important market segments
But….
At the same time, there are many booming markets for lightweight – and low cost - OCPP
implementations
That is why we are turning our attention to OCPP2.Lite!

Open Charge Alliance © 2014-2024

2 of many examples of markets for OCPP2.lite
A booming market: 2 wheelers inIndia

75 Million e2w in2030

10.5 Million e4w
in 2030

EV adoption will be led by 2wheelers in India with a 7:1 ratio

Mobile networks are an important
cost factor in Kenya

OCPP and error codes•

In April OCA updated the whitepaper “Improving Uptime Monitoring with OCPP”•This white paper describes how OCPP can be used to detect and (in some cases)
avoid downtime of a charging station.

•In the updated appendix, you can find the ChargeX Minimum Required Error
Codes (USA)•We will add more regionally required error codes to the appendix in future

Open Charge Alliance © 2014-2024

OCPP for battery swapping stations•

Together with front runner companies fromKorea and India we are exploring how OCPP canbe used to manage battery swapping stationsfor 2- and 3-wheelers•

More to come soon!

What all Grid Codes have in common
Grid codes across the world cover the same 4 aspects: a ‘Distributed energy resource’ (i.e., abidirectional vehicle) must:

A. Adjust behavior according to the grid frequency and voltage
B. Continue operation despite grid ‘hick-ups’
C. Listen to a direct ‘STOP!’ signal
D. Detect if the grid is down: do not feed into the grid when it is down and when the grid comes backup, reconnect with care

Open Charge Alliance © 2014-2024

Example of a DER Curve that tells the Charging
Station how to react to grid conditions
The Charging Station (in case of DC charging) orthe EV (in case of AC charging) must continuously
monitor the grid voltage.
When the Charging Station/EV detects that theGrid Voltage is too low or too high, it mustchange its charging behavior according to the‘Curve’.

Globally, there are more than 7000 Grid
Operators, with possibly hundreds of different
requirements at the moment – but the principle isthe same.
