A Comparison of OCPP 1.6 and OCPP 2.0.1: Choosing the Right Version for Electric Vehicle Charging Infrastructure

The Open Charge Point Protocol (OCPP) is a crucial communication standard that facilitates seamless interaction between electric vehicle charging stations and central management systems. With the development of the protocol, two significant versions have emerged – OCPP 1.6 and OCPP 2.0.1. Each version offers its own set of advantages and disadvantages, making the choice between them a critical decision for charging infrastructure operators and manufacturers.

OCPP 1.6 Advantages

One of the primary advantages of OCPP 1.6 is its widespread usage and integration into numerous charging infrastructures. Its proven stability and compatibility over time have made it a reliable choice for many operators. Furthermore, its relatively simple structure and implementation make it a preferred option for manufacturers and operators.

However, OCPP 1.6 does have its limitations. It offers limited functionalities compared to the more recent version, OCPP 2.0.1. Additionally, it lacks some of the latest security features, which could potentially lead to certain security vulnerabilities.

OCPP 2.0.1 Advantages

OCPP 2.0.1 addresses some of the limitations of its predecessor by focusing on enhanced security and advanced features. It offers safer data transmission and authentication, making it a more secure option. The inclusion of advanced functionalities such as smart charging, reservation capabilities, and improved remote diagnostics further enhances its appeal.

Moreover, OCPP 2.0.1 facilitates improved communication through enhanced message formatting and data models, allowing for more efficient exchange of information between charging stations and central management systems.

However, there are also drawbacks to consider. The advanced features of OCPP 2.0.1 can lead to increased complexity in implementation, which may pose challenges for some manufacturers and operators. Additionally, its lower adoption rate compared to OCPP 1.6 can potentially result in compatibility issues with certain charging infrastructures.

Conclusion

When deciding between OCPP 1.6 and OCPP 2.0.1, it is essential to carefully consider the specific requirements of the charging infrastructure, the technical capabilities needed, and the budget constraints. OCPP 1.6, with its widespread usage and proven stability, remains a popular choice. However, it may not offer the advanced features and security measures that OCPP 2.0.1 provides.

On the other hand, OCPP 2.0.1 offers enhanced security, advanced functionalities, and improved communication capabilities. Yet, its more complex implementation and lower adoption rate can present challenges.

Furthermore, it is crucial to factor in the cost associated with OCPP testing and certification programs, which can be expensive. Balancing the technical benefits against the financial implications is essential in making the appropriate version selection.

In conclusion, choosing the right version of OCPP depends on various factors, including the specific requirements of the charging infrastructure, the desired technical capabilities, and the budget constraints. By carefully evaluating these aspects, operators and manufacturers can make an informed decision that aligns with their needs and goals.
