Hubject
Hubject is a leading eRoaming hub for EV charging that enables interoperability between charge point operators (CPOs) and e-mobility service providers (eMSPs) through its Intercharge network. In practice, Hubject helps EV drivers access many different charging networks with one contract/app/card by connecting the backend systems that handle authorization, tariffs, session data, and settlement across operators.
What Is Hubject Used For?
Hubject is typically used to simplify roaming relationships:
– Connect a CPO to many eMSPs without negotiating many one-to-one agreements
– Expand a network’s reach so more drivers can charge at your stations
– Support cross-border charging access with standardized backend connectivity
– Enable consistent roaming operations (IDs, tariffs, session records, clearing)
Hubject and Intercharge eRoaming
Hubject’s Intercharge platform acts as a central connector for roaming:
– CPOs “open” their charge points to multiple mobility partners
– eMSPs can offer their customers broader charging access
– Backend systems exchange data needed for authentication and billing
This reduces integration complexity and improves network utilization by making chargers reachable to more drivers through roaming.
Hubject and Plug & Charge
Hubject also offers Plug&Charge services based on ISO 15118, enabling automatic, certificate-based authentication between the EV and the charger—no RFID card or app needed at the point of charge.
Hubject PKI and Certificates
Plug&Charge relies on a Public Key Infrastructure (PKI). Hubject operates PKI services and documentation for participants, including certificate policies and the issuance flow for ISO 15118 certificates used in Plug&Charge ecosystems.
Why Hubject Matters for Charging Networks
For CPOs and eMSPs, Hubject can deliver:
– Faster scaling of roaming coverage with fewer integrations
– Higher charger utilization by attracting more roaming users
– Improved user experience via interoperable access and, where supported, Plug&Charge automation
– Standardized processes for roaming operations and settlement
