The Evolution of OCPP Protocol: From Origins to OCPP 2.1
The Evolution of OCPP Protocol: From Origins to OCPP 2.1
Origins of OCPP
In 2009, the Dutch nonprofit organization ElaadNL, founded by distribution system operators (DSOs), initiated the Open Charge Point Protocol (OCPP). Aiming to deploy 10,000 EV charging stations across the Netherlands, ElaadNL sought a standardized communication method for interoperability among diverse hardware suppliers. At the time, no universal standard existed, prompting ElaadNL to develop OCPP—a groundbreaking framework for EV charging infrastructure.

OCPP 1.6: The Global Standard
Launched in 2015, OCPP 1.6 quickly became the most widely adopted version globally, solidifying its role as a must-have protocol for EV charging manufacturers entering international markets. Its support for JSON messaging via WebSocket ensured lightweight, efficient communication, while features like smart charging and real-time monitoring empowered operators to optimize energy distribution and grid stability23. By 2023, OCPP 1.6 remained the backbone of over 40,000 charging stations worldwide.

Key Features of OCPP 2.1
- Bidirectional Charging & V2G Support
- Enables Vehicle-to-Grid (V2G) energy transfer, allowing EVs to feed power back into the grid.
- Aligns with ISO 15118-20 for seamless plug-and-charge experiences and multi-contract certificate management.
- Distributed Energy Resource (DER) Integration
- Empowers charging stations to act as DERs, supporting grid stability through dynamic power factor adjustments and frequency control.
- Enhanced Smart Charging Modes
- Introduces seven operational modes, including Central Setpoint (for CSMS-driven charging/discharging targets) and Local Load Balancing (for real-time grid optimization).
- Prepaid & Ad-Hoc Payment Solutions
- Supports local cost calculations compliant with regulations like CTEP, enabling credit card payments and multi-language interfaces.
- Allows temporary payments via debit/credit cards or digital wallets without requiring eMSP contracts.
- Advanced Security & Flexibility
- Expands certificate management for longer chains and revocation lists.
- Adds DER-specific alarms for issues like current imbalance or frequency deviations.
