What is the Open Charge Point Protocol (OCPP)?

Suppliers of software for companies that provide charging station management services often refer to the acronym OCPP. What exactly is this protocol and what can you do with it?

The Open Charge Point Protocol (OCPP) is an open protocol that describes how communication should occur between the electric car charging point and a back office system such as Last Mile Solutions. OCPP ensures that different systems “talk” to each other in a standardized way.

To ensure that the market becomes uniform as possible, OCPP, like OCPI and OCHP, has been developed as an open protocol. This means that anyone can use the protocol and also that anyone can participate in the development of OCPP. This promotes interoperability and contributes to vendor independence. This is good for confidence in the charging infrastructure.

In 2009, e-laad foundation started with some partners, including Last Mile Solutions with the development of OCPP. Meanwhile there are already more than 400 participants from 35 countries including USA, Singapore, Germany, France, Great Britain and Russia.
