Streamlining Hub Integration for a CPO Platform through Advanced OCPI Capabilities

A prominent Charge Point Operator (CPO) platform offering a comprehensive Charging Station Management System (CSMS) faced the challenge of expanding its service reach and streamlining connectivity with multiple e-Mobility Service Providers (eMSPs). The goal was to harness existing roaming capabilities to expose its network to a wider user base efficiently. Despite having direct connections to eMSPs via OCPI, the client sought to enhance its roaming capabilities through a strategic integration with a leading EV roaming hub.
Streamlining Hub Integration for a CPO Platform through Advanced OCPI Capabilities


The primary challenge was to integrate with a new hub platform, Gireve, which facilitated connections with multiple eMSPs using the Open Charge Point Interface (OCPI) protocol. The client's existing OCPI version was not fully equipped to handle hub-based integrations, necessitating an upgrade to a later version of the protocol, enabling better hub support. Additionally, there was a need to reconcile the client's roaming capabilities with Gireve’s requirements without extensive redevelopment of existing systems.


The solution entailed a strategic upgrade from OCPI version 2.1.1 to 2.2.1, better suited for handling hub integrations. This decision was underpinned by several critical steps:

  • Discovery Phase: An initial assessment revealed that the platform's infrastructure could support an OCPI upgrade, leveraging existing capabilities supporting the major changes OCPI v2.2.1 required.
  • Protocol Upgrade: Transitioning to OCPI 2.2.1 enabled the platform to adopt features essential for hub operations, such as message routing headers, broadcast push, support for platform to hub integration, and support for hubs routing requests internally, facilitating more efficient communication across the network.
  • Hub Integration: This upgrade made it possible to implement broadcast push functionality, allowing the platform to disseminate updates to all eMSPs connected via Gireve, thus improving data synchronization and service delivery.


The implementation was approached methodically:

  • Consensus on OCPI version usage and module compatibility between the platform and Gireve.
  • Staging environment development and testing to ensure integration efficacy without impacting existing services.
  • Ongoing collaboration with Gireve to tackle technical hurdles, especially concerning the hub's readiness for OCPI 2.2.1 and message routing optimization.

While still in staging at the case study's writing, the upgrade and integration efforts are set to significantly enhance the platform's roaming capabilities. The connection to Gireve's hub opens the door to a wider network of eMSPs, thus broadening potential user access and elevating the CPO platform's market position. The transition to OCPI 2.2.1 not only underscores the platform's commitment to technological advancement but also sets a new standard for efficiency and scalability in EV charging service management.
