OCPP 1.6
Overview
The Open Charge Point Protocol (OCPP) is an application protocol for communication between charging stations for electric vehicles (EVs) and a central management system, also known as a charging station network. It is comparable to communication between cell phones and cell phone networks. The original version of OCPP was developed by LogicaCMG and Enexis led by Michel Bayings with Franc Buve, Patrick Rademakers and Joury de Reuver. The first version was released in 2009. The OCPP enables smooth communication between chargers and management platforms, allowing centralized monitoring and load control.
