What is OCPP?
OCPP stands for “Open Charging Point Protocol”. We can simply understand it as a language used to communicate between connected charging stations and charging management systems (CSMS).
OCPP was originally developed by the E-Laad Foundation (now ElaadNL) in 2009 to create an open communication standard that would enable Dutch charging stations and systems from different vendors to easily communicate with each other. Now it is managed by the Open Charging Alliance (OCA), which aims to promote open standards for electric vehicle charging networks worldwide.
What is OCPP used for?
Here are three key players in the EV charging landscape that require the power of OCPP:
EVSE manufacturers: These are hardware companies that make EV chargers.
CSMS Software Providers: Most are software companies that build EV charging station management systems (CSMS).
CPO: Charging point operators build a network of electric vehicle charging stations and have customer relationships.
The three businesses are usually separate businesses, but in some cases, a single company chooses to take on the roles of two or all three of the above.
What can an EV charger with OCPP function do?
Here are some basic operations for EV chargers using OCPP
- User authorization to start charging – Remotely modify charger configuration (settings).
- Real-time monitoring of charging station status.
- Real-time charging session data is transmitted to the central management system.
- Remote charging session control (start/end).
-EVSE fault diagnosis.
- Electric vehicle users book charging sessions (via mobile/web app).
- Smart charging .
- Charger firmware management.
- Remote unlocking such as charging cable.
Key benefits of OCPP
-Ability to connect any CSMS with any charging station, regardless of the vendor (provided both the CSMS and the charging station are OCPP compliant).
-Adaptable to all types of charging technologies (GB/T, CHADMEO, CCS 2, NACS, CCS1)
- Unified charging station access, roaming, and billing services for EV customers – With the openness of the protocol, it is relatively easy to add new features and improvements.
So why should we choose an OCPP-compliant EV charger?
Reliability and uptime are critical for all EV charging service providers. Service downtime due to hardware failure can be costly. The functions provided by OCPP can enable charging station operators to monitor and remotely manage charging piles in real time through the backend, saving a lot of time, labor costs, and later maintenance costs.
