OCPP : OCPP 2.0.1

OCPP 2.0 made its first appearance in 2018 as the successor to OCPP 1.6. However, OCA, in collaboration with the community, decided that version 2.0 would benefit from additional features. Thanks to the hard work of both the OCA team and the community, OCPP 2.0.1 was introduced in 2020 and is on its way to replacing OCPP 1.6 as the new industry standard for communication between the CS and CSMS.

OCPP 2.0.1 has the following improved/added functionalities in comparison to OCPP 1.6:  

• Device Management Features to get and set configurations and also to monitor a Charging Station. 
• Improved transaction handling 
• Added security 
• Added smart charging functionalities 
• Support for ISO 15118 
• Display and messaging support 

• Many additional improvements requested by the EV charging community  

Note that OCPP 1.6 and OCPP 2.0.1 are not compatible. OCPP 2.0.1 ed3 was approved as an IEC standard (IEC63584) in 2024.
