OASIS HUB’s Hub role sits at the centre of the EV charging ecosystem.
It routes charging data between operators and service providers, translates between protocol versions, clears that data across partners, and settles balances automatically - so every player in your network can focus on their business, not on integration plumbing.
An EV driver wants to charge at a station that belongs to CPO A, but they have an account with eMSP B. Without a Hub, CPO A and eMSP B would need a direct integration and with hundreds of operators in any given country, that means thousands of point-to-point connections.
A Roaming Hub solves this with a star topology: every CPO and every eMSP connects once to the Hub.
The Hub routes sessions, translates protocols, corrects and clears data, and settles balances. As an impartial entity, it also makes disputes easy to resolve.
One connection gives you access to the entire network.
OASIS HUB can act as CPO, eMSP, and Hub simultaneously- or as a pure Hub if that's all you need.
Partners running different OCPI versions? No problem. OASIS HUB translates automatically between OCPI 2.1.1, 2.2, 2.2.1, and 2.3.0 in both directions, in real time. No manual mapping, no data loss.
Onboard a new CPO or eMSP in hours, not weeks. The guided wizard walks through partner details, credential exchange, OCPI handshake validation, test sync, and go-live. Progress bar shows exactly where you are at every step.
Control exactly which traffic flows where. Block sessions from a specific partner, route all traffic from a country to a preferred eMSP, or re-route based on connector type. Wildcard matching lets you set rules for entire regions at once.
When sessions flow through OASIS HUB, the money flows with them. OASIS HUB runs the full cycle: CDR reconciliation, discrepancy detection, reports, invoices, SEPA files, and multi-party netting.
Then you choose how the money moves:
- Pay the network with one SEPA file. One upload. The eMSP pays every CPO their drivers used.
- Pay OASIS HUB. The eMSP pays OASIS HUB once. OASIS HUB pays the CPOs.
Hundreds of transfers become one.
Automatically compare your CDR records with your partners' CDR records after every settlement period. Missing CDRs and amount mismatches are flagged immediately - before invoices are sent. Per-CDR dispute resolution workflow included.
Track the commercial side of every partnership: revenue shares, SLA terms, minimum commitments, and agreement lifecycle (Draft → Proposed → Active → Suspended → Terminated). All in one place, with full audit history.
Interoperability only works if you speak every dialect. OASIS HUB supports more protocol versions than any competitor - so no partner is ever left out.
The Open Charge Point Interface protocol is the language CPOs and eMSPs use to exchange location data, session information, tokens, tariffs, and CDRs. OASIS HUB supports all four active versions simultaneously.
OASIS HUB supports OICP 2.3 natively - giving your partners access to other Hubs through a single connection.
The Open Charge Point Protocol is how chargers talk to the management system. A hub that also manages chargers directly needs to support every generation - from legacy 2018 hardware to the newest 2026 models.
ISO 15118 enables vehicles to identify themselves at the charger - no card, no app, no QR code. As a Hub, we can manage the certificate infrastructure for all your CPO partners from one place, and extend Plug & Charge to their entire network.
The two main pure-hub competitors are A and B. Here's how OASIS HUB stacks up and where it goes further.

The Hub role isn't just for large network operators.
Any business that connects multiple parties benefits.
Run the national EV roaming Hub for a country. Connect every CPO and eMSP in the market through a single platform. Handle settlement and compliance centrally.
Offer EV charging as a service to your customers by connecting multiple CPO partners. You manage the driver relationship; the hub routes sessions to whichever CPO is nearest.
Serve corporate clients who want their employees to charge anywhere. Connect to multiple CPO networks and present a unified charging experience under your brand.
Run your own chargers, serve your own drivers, and connect third-party partners - all from one OASIS HUB deployment. One system, one team, one source of truth. Save 40–60% vs separate platforms.
The guided onboarding wizard eliminates the back-and-forth that makes roaming partnerships slow to set up.
Whether you're launching a national roaming network or connecting a handful of partners, OASIS HUB gives you everything you need in one platform.
