OCPI, or Open Charge Point Interface, facilitates real-time data exchange between Charge Point Operators (CPO) and Mobility Service Providers (MSP) through eight modules including locations, sessions, and commands. The document outlines the functionality of each module, emphasizing transactions such as reserving charge points for electric vehicles. Key procedures involve credential exchanges and the push/pull dynamics of information sharing to enhance user experience in locating and utilizing charging stations.

16. Scenario

17. Example (reserve now!)
• Pre-condition: CPO and MSP has exchanged credential information with OCPI.
• Pre-condition: The CPO and MSP exchanged location information with OCPI.
1. User need power for his EV
2. The user uses an app from his MSP to search for available charge points.
3. The user reserves the charge point with his app.
4. The MSP system sends the reserve Command with the OCPI to the CPO.
5. The CPO receives the command from OCPI and reserves the charge pole for
x minutes.

18. The Wrap up..
• OCPI Stands for: Open Charge Point Interface
• Information exchange between CPO – MSP and vise versa
(uniform, open, realtime, Bilateral (get, push))
• 8 modules:
• Version
• Credentials
• Token
• location
• CDR
• Session
• Commands and Tariff
• Think about.. The phone scenario
