EVs provide a sustainable and eco-friendly alternative to traditional gasoline cars. As the adoption of EVs continues to grow, the infrastructure supporting them must evolve as well. The Open Charge Point Protocol (OCPP) is crucial in EV charging. In this blog, we’ll delve into the significance of OCPP in the context of EV charging, features, compatibility, and impact on the efficiency and security of charging infrastructure.
What is OCPP in EV Charging?
The key to establishing an efficient, standardized EV charging network is the OCPP. OCPP serves as the communication protocol between the EV charger and the charge point management systems (CPMS), ensuring seamless exchange of information. This protocol is essential to enable interoperability between charging stations and network management systems.
OCPP 1.6 and OCPP 2.0.1 were developed by the Open Charge Point Protocol Alliance.OCPP comes in different versions, with OCPP 1.6j and OCPP 2.0.1 being prominent iterations. OCPP 1.6j, an earlier version, and OCPP 2.0.1, the latest version, serve as the backbone for communication in EV charging networks. Let’s explore the key differences between these versions.
What are the Main Differences Between OCPP 1.6 & OCPP 2.0
OCPP 1.6j and OCPP 2.0.1 are significant milestones for the Open Charge Point Protocol. The transition from 1.6j into 2.0.1 introduces important functionality, security, and data exchange improvements. OCPP 2.0.1 includes features that improve grid integration, data exchange capabilities, and error handling. Upgrade to OCPP 2.0.1, and charging stations will be up-to-date with industry standards. Users can expect a more reliable charging experience.
Understanding OCPP 1.6
As a version of OCPP, the OCPP1.6j protocol supports functions such as starting charging, stopping charging, and getting charging status. In order to ensure the confidentiality and integrity of communication data and prevent data tampering, OCPP adopts an encryption and authentication process. Meanwhile, OCPP 1.6j supports real-time monitoring and control of the charging device to ensure that the charging device responds to the user's operation in a real-time manner.
As the EV charging industry advanced, however, it became apparent that an updated protocol was needed to address new challenges, offer enhanced features, and be in line with evolving industry standards. This led to the creation of OCPP 2.0.
What Makes OCPP 2.0 Different?
OCPP 2.0 is a significant evolution of its predecessor. It introduces key differences that reflect the changing needs of the electric vehicle ecosystem.
1. Enhanced Functionality:
OCPP 2.0 offers a more extensive set of features than OCPP 1.6. The protocol provides improved error handling capabilities, grid integration capabilities, and a larger data exchange framework. These improvements contribute to a robust and more versatile communication protocol.
2. Improved Security Measures:
Security is a major concern for any communication protocol. OCPP 2.0 incorporates more advanced security measures to address this. The enhanced encryption and authentication mechanisms offer a higher level of protection against cyber threats. This gives users and operators confidence that their data and transactions are safe.
3. Backward Compatibility:
OCPP 2.0 is backward compatible, recognizing the widespread use of OCPP 1.6. This means charging stations that are still running OCPP 1.6 will be able to interact with central systems upgraded to OCPP 2.0. This backward compatibility allows for a smooth transition and prevents any disruptions to existing charging infrastructure.
4. Future-Proofing:
OCPP 2.0 was designed to be forward-looking, taking into account the expected developments in the EV Charging sector. Charging station operators can position themselves as industry leaders by adopting OCPP 2. This will ensure that their infrastructure is relevant and adaptable for future advances.
The Impact of the EV Charging Industry
The move from OCPP 1.6 (the previous version) to OCPP2.0 represents a commitment to stay abreast of the latest technological advances. Charging stations that use OCPP 2.0 have enhanced security features, and they also contribute to standardized and interconnected charging infrastructure.
Operators who are looking to upgrade or deploy new charging stations should consider carefully the benefits offered by OCPP 2. Its enhanced functionality, security features, backward compatibility, and future-proofing make it an excellent choice for anyone looking to offer a seamless charging experience to electric car users.
Protocols like OCPP play a crucial role in shaping the efficiency and interoperability of the electric vehicle charging ecosystem as it expands. The move from OCPP 1.6 (to OCPP 2.0) represents a positive step toward a future of EV charging that is more secure, feature-rich, and standardized. By embracing these innovations, the industry can remain at the forefront of technology and contribute to a connected and sustainable transportation landscape.
