OCPP (Open Charge Point Protocol) is a widely adopted communication protocol in electric vehicle (EV) charging solutions. It is an open, vendor-neutral standard that enables the interoperability of EV charging stations and central management systems.

OCPP allows for seamless communication and data exchange between EV charging stations and the central management system, providing a standardized interface for monitoring, controlling, and managing charging infrastructure. It ensures compatibility and easy integration of various charging station brands and models, regardless of the manufacturer.

The Open Charge Point Protocol (OCPP) is managed and overseen by the Open Charge Alliance (OCA). The OCA is an international consortium that develops and promotes the OCPP standards for EV charging networks. The Open Charge Alliance (OCA) oversees the Open Charge Point Protocol (OCPP) and is based in the Netherlands

Different Versions Of OCPP

The Open Charge Point Protocol (OCPP) has several versions, each introducing new features, enhancements, and improvements to the protocol. Here are some of the different versions of OCPP:

  • OCPP 1.5
  • OCPP 1.6
  • OCPP 2.0
  • OCPP 2.0.1

It’s important to note that different charging stations and central management systems may support different versions of OCPP. To ensure compatibility, it’s crucial to verify the OCPP version supported by the specific charging infrastructure components you are using and ensure they are compatible.

Difference Between OCPP and OCPI

  • OCPP and OCPI have different functionalities, communication architectures, levels of industry adoption, and use cases within the EV charging industry.
  • OCPP primarily focuses on communication between charging stations and central management systems, while OCPI facilitates communication and data exchange between different entities in the charging ecosystem. Both standards play important roles in enabling interoperability and advancing the development of EV charging infrastructure.

How OCPP Works For EV Charging

Step 1

The charging station is connected to a CMS; they establish a secure communication channel using OCPP.

Step 2

The charging station periodically sends status updates to the CMS, providing information about its availability, charging sessions, and other relevant data.

Step 3

The CMS can remotely control and monitor the charging station, initiating or terminating charging sessions and adjusting charging parameters.

Step 4

OCPP also enables the exchange of meter values, allowing the CMS to collect information about energy consumption and facilitate billing and reporting.

Step 5

Additionally, OCPP supports firmware updates and diagnostics, allowing the CMS to remotely manage the charging station’s software and perform troubleshooting tasks.

Step 6

By adhering to OCPP, charging stations and CMSs from different manufacturers can communicate seamlessly, enabling EV drivers to access charging services without compatibility issues.

Step 7

Lastly, OCPP ensures reliable data exchange, efficient management, and a user-friendly charging experience for EV owners.

Various Stakeholders In The Field Of EV Charging Who Has A Greatly Important

EV Charging Hardware Manufacturers

These hardware companies manufacture the EV chargers themselves.

Charging Station Management System (CSMS) Software Providers

These software companies build charging station management systems (CSMS).

Charge Point Operators (CPOs)

These charge point operators (CPOs) own the customer relationship. They’re the brands that EV drivers interact with.

Benefits of Implementing OCPP in EV Charging Solutions


OCPP promotes interoperability between charging stations from different manufacturers. This means EV drivers can use any OCPP-compliant charging station, regardless of the charging station’s brand or model. It provides flexibility and convenience for EV owners, as they are not restricted to a specific charging network.


OCPP supports the scalable deployment of charging infrastructure. It allows for the easy addition of new charging stations to an existing network without complex integration processes. This scalability is crucial for accommodating the increasing number of EVs on the road and meeting the growing demand for charging services.

Centralized Management

OCPP facilitates centralized charging station management through a central management system (CMS). The CMS can remotely monitor and control charging stations, gather data on charging sessions, manage user authentication and billing, and perform software updates. This centralized approach streamlines the operation and maintenance of charging infrastructure.

Flexibility for Service Providers

OCPP allows providers to customize their EV charging offerings, including ensuring EV charging station accessibility. They can tailor the user experience, define pricing and billing models, and integrate additional services such as renewable energy integration or demand response programs, all while prioritizing EV charging station accessibility. This flexibility enables service providers to differentiate themselves in the market and cater to specific customer needs, ensuring that EV charging stations are easily accessible to all users, regardless of their mobility requirements. By incorporating EV charging station accessibility into their offerings, service providers promote inclusivity and enhance the overall charging experience for a broader range of EV users.


OCPP’s wide adoption worldwide has helped establish an ecosystem of hardware and software providers. This competitive marketplace drives innovation, improves product offerings, and enhances affordability for charging station operators and EV owners.

The protocol has also evolved, with new versions introducing additional features, enhancements, and bug fixes. This continuous custom mobile app development solution ensures that OCPP remains aligned with the changing needs of the EV industry, maintaining compatibility and addressing any limitations.

In conclusion, OCPP has become an essential enabler of the EV charging infrastructure, fostering interoperability, flexibility, and scalability. OCPP’s significance will likely increase as the EV industry grows, driving further innovation and stakeholder collaboration.
