OCPP protocol, also known as Open Charge Point Protocol, is an open standard protocol for communication between electric vehicle charging piles and charging pile management systems (CSMS). It allows interoperability between charging piles and management systems produced by different manufacturers, thereby providing electric vehicle users with a wider charging network.

What role does OCPP play in EV charging operations?

OCPP is an open communication protocol that allows the EV Charging Stations and the Charging Station Management System (CSMS) to communicate with each other.

• -OCPP helps the EVSE and CSMS to communicate with each other by creating an open platform.
• -Following are some of the basic operations supported via OCPP.
• -Authorization of EV user for start of charging including Local List of Authorization
• -Remote modification of Charger configuration (settings)
• -Real-time status of charging stations (available, unavailable, faulted, suspended EV/EVSEcharging, preparing, finishing)
• -Real time charging session data transfer to central management system
• -Remote charging session control (start/end)
• .-EVSE Fault Diagnosis
• -Reservation of charging time slot by EV user (through a customer facing mobile/web app)
• -Smart Charging
• -Firmware management of chargers
• -Remote unlocking of charging gun etc.
