53:. Michel Bayings was the project leader who also contributed on the business and functional parts. The technical design and specs were developed by Franc Buve, Patrick Rademakers, and several others from LogicaCMG. Its aim was to create an open application protocol which allows EV charging stations and central management systems from different vendors to communicate with each other. It is in use by a large number of vendors of EV charging stations and central management systems all over the world.

through market forces, encourage charging station manufacturers and network providers to compete on price, service, product features, and innovation – all of which encourages demand by charging station owners. The end result is a significant benefit to EV drivers as the charging station infrastructure expands.

The security part of OCPP defines an end-to-end security design architecture, with implementation guidelines for both charging stations and
Central Management System. It was first introduced in 2018 and now is in its third revision. Correct implementation of the OCPP Security guidelines can protect

This certification program will help the EVSE manufactures & CSMS platform to exhibit a clear status of their OCPP implementation to their clients. Likewise, it will also be beneficial for the consumers of the OCPP products without a need to test & validate the implementation themselves.

OCPP also makes it easier to create a large-scale, visible network that uses a range of different charging stations since there is a requirement for only one operating system. Proponents of OCPP also cite a reduction in development costs since software designed to provide additional functionality

Charging station owners, or hosts, are less vulnerable to individual system suppliers if a charging station manufacturer ceased to exist, the host could switch to another OCPP-based network. Giving charging station customers choice and flexibility to use any network on any charging station would,

For now only OCPP 1.6 can be fully tested and certified. OCPP versions older than OCPP 1.6 (such as OCPP 0.7, OCPP 1.2, and OCPP 1.5) as well as OCPP 2.0 are not covered under the current OCPP certification program. Open Charge
