OCPP is the abbreviation for Open Charge Point Protocol. It serves as an open-source communication standard for electric vehicle charging stations and network software companies. OCPP was established in 2009 by the Open Charge Alliance, which is designed to be cost-free, open-source, and easily implementable. It enables interoperability by allowing users to select and switch EV software, promoting healthy competition in the market. OCPP-compliant hardware offers various advantages, including centralised charging station management, increased visibility, and adaptability with different networks. This protocol ensures the safety of charging station investments, as it allows users to avoid compatibility issues even if manufacturers cease operations. OCPP is recognised globally as a crucial standard for facilitating communication and interoperability within the EV charging industry.
What is the need for EVs & EV chargers to be OCPP compliant?
Ensuring OCPP compliance holds significance for Electric Vehicles and EV chargers. It guarantees smooth interaction among various charging stations and EVs, irrespective of the manufacturer. This implies that any charging station adhering to OCPP can be used by EV owners, while operators can oversee their stations with software complying with OCPP. Further insights into the advantages of OCPP will be explored in the section titled ‘Benefits of OCPP.’
Benefits of OCPP

How Does OCPP Work?
OCPP, or Open Charge Point Protocol, functions as a standardized communication language between Electric Vehicles and charging stations. When an EV is connected to a charging station, OCPP enables them to exchange information smoothly. Here’s a simplified breakdown of how OCPP works:
- Connection Establishment: The EV and charging station establish a connection when the EV is plugged in for charging.
Information Exchange: OCPP facilitates the exchange of essential data between the EV and the charging station. This includes details like charging status, power level, and other relevant information.
Command Transmission: Charging stations can send commands to EVs through OCPP. For example, a command to start or stop charging.
Real-time Monitoring: OCPP allows real-time monitoring of the charging process. Charging stations can receive updates from the EV, ensuring smooth communication during the entire charging session.
Status Reporting: The protocol enables both the EV and the charging station to report their status. This helps in identifying any issues or completing the charging process successfully.
Interoperability: OCPP’s standardized nature ensures interoperability. This means that EVs and charging stations from different manufacturers can communicate effectively as long as they adhere to the OCPP standard.
Conclusion
OCPP, or Open Charge Point Protocol, plays a crucial role in standardizing communication between Electric Vehicles and charging stations. By promoting interoperability, streamlining operations, and enhancing user experience, OCPP contributes to the growth and efficiency of the EV charging industry. Its open-source nature ensures adaptability, security, and intelligent charging capabilities, making it a widely recognized and essential standard in the global EV ecosystem
