The Open Charge Alliance frequently publishes Whitepapers and other documentation about implementing OCPP and various applications. In April the Alliance has published three new whitepapers that are available for download now. These publications can be downloaded directly below.
- New "Mode 1/2 Only" Charging Stations added to OCPP Certification
- Improving Uptime Monitoring with OCPP
- What's new in OCPP 2.0.1?

New "Mode 1/2 Only" Charging Stations added to OCPP Certification
The technology around charging station is still evolving. Usually most attention goes to the development of charging stations that deliver ever more power: fast chargers, ultra-fast chargers and megawatt chargers. At the same time, the need for low-cost charging stations for at home, office or parking lots is growing. For this market a new type of charging station has recently been developed: the so-called "mode 1&2-only" charging station. In this white paper we explain what it is, and how if differs from a regular charging station. We will also explain how certifying such a device differs from certifying a regular charging station.
During the Korea OCPP Technical Committee meeting on march 17th in Seoul Lonneke Driessen presented the OCA Whitepaper “New "Mode 1/2 Only" Charging Stations added tot OCPP Certification” to Dr. Jae-Jo Lee. Dr. Jae-Jo Lee is the principal researcher at the power grid research division of the Korea Electrotechnology Research Institute (KERI).
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. Note, that OCPP by itself is not responsible for downtime — it is just a set of messages between a charger and its management system. A charging station operator (CSO), however, can utilize certain messages and configuration options to allow for early detection of problems.
What's new in OCPP 2.0.1?
In 2020 OCA released OCPP 2.0.1, which is a big step forward from OCPP 1.6. OCPP 2.0.1 is not an incremental extension of OCPP 1.6, even though it uses many of the same concepts and even shares some of the same messages. As a result, OCPP 2.0.1 is not backward compatible with OCPP 1.6. For example, the transactionhandling has changed, which was required in order to support configurable start and end conditions for transactions, and an entire new concept, the device model, was introduced to provide advanced configuration
and monitoring capabilities. This white paper explains which features are new in OCPP 2.0.1.
During the March 20th Alliance for Transportation conference, Franc Buve got the chance to present these new publications to Philip Jones , Executive Director of the Alliance for Transportation Electrification (ATE).
