OCPP Protocol Upgrade Needs and Challenges
As electric vehicle (EV) charging infrastructure rapidly expands, protocol upgrades have become a critical issue for EV charger manufacturers. Versinetic, a provider of EV charging solutions, officially launched the OCPP Migration Decision Matrix software tool on July 24, 2026, specifically designed to assist engineering teams at EV charger manufacturers in evaluating the best timing and strategy for migrating from OCPP 1.6 to OCPP 2.1. The tool offers a structured analytical framework covering technical, commercial, and operational dimensions, including fleet size, field upgrade capabilities, customer requirements, and product roadmaps, helping manufacturers develop migration plans tailored to their practical needs.
Versinetic noted that OCPP 1.6 remains the most widely deployed communication protocol in global EV charging infrastructure. However, as procurement specifications increasingly incorporate OCPP 2.x functionality requirements, manufacturers must decide how to introduce the new protocol without disrupting existing development programs. The company emphasized that upgrade decisions should focus on actual commercial and operational value rather than merely pursuing the latest version number. Compared to OCPP 1.6, OCPP 2.1 introduces several key enhancements, including improved security, a more comprehensive device model, advanced diagnostic tools, smarter charging capabilities, and support for emerging technologies such as vehicle-to-grid (V2G). Whether these features deliver tangible benefits has become a crucial consideration for manufacturers evaluating upgrades.
Three Common Upgrade Pitfalls for Engineering Teams and Solutions
In analyzing the upgrade processes of EV charger manufacturers, Versinetic identified three common challenges frequently encountered by engineering teams. These issues can lead to delays, increased costs, or failure to meet customer needs. To address these challenges, Versinetic recommends adopting a modular software architecture that separates protocol logic from core application functionality, enabling support for both OCPP 1.6 and 2.x versions while reducing future engineering burdens. Ricardo Silva, a firmware engineer at Versinetic, stated, "Supporting OCPP 2.1 does not automatically require rebuilding an entire platform. The manufacturers making the fastest progress typically focus on capabilities their customers actually need and design software architectures that allow OCPP 1.6 and 2.x to coexist, ensuring the upgrade process does not compromise the stability of existing products."
Silva further emphasized that protocol migration should be driven by business priorities and customer requirements rather than version numbers. He stressed that manufacturers should establish flexible software architectures to enable product evolution without disrupting development progress. To this end, Versinetic advises a phased migration strategy, maintaining the stability of OCPP 1.6 products while gradually introducing OCPP 2.x on new platforms or selected deployments. This approach not only reduces upgrade risks but also ensures that new functionalities deliver clear commercial and operational benefits. For example, OCPP 2.1’s enhanced security and smart charging features can improve charger reliability and user experience, thereby strengthening product competitiveness.
The OCPP Migration Decision Matrix is now available for EV charger manufacturers, aiming to help engineering teams navigate complex technical and commercial considerations to identify the most appropriate upgrade path. The tool not only reduces uncertainties during migration but also accelerates the modernization of charging infrastructure, ensuring manufacturers maintain a competitive edge in a rapidly evolving market. As demand for EV charging continues to grow, protocol upgrades will become an unavoidable challenge for manufacturers, and Versinetic’s tool provides a systematic solution for the industry.
