OCPP 2.1 is designed for smarter, more efficient, and user-friendly EV charging solutions. It is part of our mission to stay ahead and to improve constantly. We reached this milestone thanks to the input and feedback we received from OCA participants and OCPP enthusiasts from all over the world! Together, we define the future of EV charging. 

What is new in OCPP 2.1? 

OCPP 2.1 includes improved and added functionalities compared to OCPP 2.0.1: 

  1. Support for ISO 15118-20: Support for ISO 15118-20 with bidirectional power transfer. 
  2. New Functional Block on Bidirectional Charging: Enablement of bidirectional energy flows (V2X), allowing EVs to act as energy sources.  
  3. New Functional Block on DER Control: Enhanced integration with distributed energy resources (DER). 
  4. Improved Smart Charging: Advanced tools for optimized energy distribution across charging stations. 
  5. Extended Transaction Options: Possibility to perform transactions with fixed costs, energy or time. Possibility to resume transactions after a forced reboot. 
  6. Battery Swapping: Support for battery swap stations for two- and three-wheelers and electric vehicles. 
  7. Local Cost Calculation: Support for local cost calculation on the charging station.  
  8. New Authorization Options:  
    • Support for Prepaid Charge Cards: Transaction cost cannot exceed prepaid card balance.  
    • Support for Ad Hoc Payment: Pay with credit or debit card via a built-in or a stand-alone credit card terminal. 
    • Secure Dynamic QR Codes: Introduction of secure dynamic QR-codes for ad hoc payment.
    • Many Additional Improvements: A variety of updates driven by feedback from the EV charging community. 
  9. Many Additional Improvements: A variety of updates driven by feedback from the EV charging community. 

What about older OCPP versions? 

OCPP 2.1 extends OCPP 2.0.1 with additional functionality. Care has been taken to make sure that all application logic developed for OCPP 2.0.1 will continue to work in OCPP 2.1. 

OCPP 1.6 has different application logic and is therefore not compatible with OCPP 2.1. Both older versions, 2.0.1 and 1.6, will continue to be supported. 

Who contributed to OCPP 2.1? 

We want to thank everyone who contributed to this milestone: the OCA technical editors, the Technology Working Group members and everyone from the EV charging industry supporting OCPP. Your hard work, input and feedback in the past months contributed to the launch of OCPP 2.1.
