EV charging that works on any network
We help charge point operators, e-mobility providers and their payment partners connect chargers to any back office, enable roaming across networks and turn every charging session into accurate billing and settlement.
What our clients are up against
Chargers from many vendors
Charging networks often run hardware from several manufacturers, and each charger must work reliably with the same central management system.
Drivers who roam
Drivers want one app or card to work on other operators' chargers, with clear prices and correct billing wherever they plug in.
Turning sessions into revenue
Every session needs authorization, a tariff, an accurate charge record and settlement between the parties involved, often across borders.
How we cover EV Charging Payments
Charger connectivity with OCPP
Connect every charger to your central system using a common protocol.
- OCPP 1.6 and 2.0.1 implementation and certification
- Charge point to central system communication architecture
- Multi-vendor charging station interoperability
Charging operations with OCPP
Run a healthy network and manage energy use across sites.
- Smart charging and load management integration
- Remote monitoring, diagnostics and firmware updates
- ISO 15118 Plug & Charge alongside OCPP
Roaming with OCPI
Let drivers charge on partner networks with one account.
- OCPI 2.2 and later integration for roaming networks
- Charge point operator (CPO) and e-mobility service provider (eMSP) connectivity
- Real-time authorization flows between networks
Tariffs, sessions and settlement
Price each session correctly and settle with every partner.
- Real-time tariff exchange between CPOs and eMSPs
- Session management and Charge Detail Record (CDR) processing
- Cross-border EV roaming and settlement

Services, case studies and tools
What is the difference between OCPP and OCPI?
OCPP is the language between a charger and its operator's central system: starting and stopping sessions, reporting meter values, applying smart charging limits and updating firmware. OCPI is the language between networks: it lets an eMSP's drivers use a CPO's chargers, sharing locations, tariffs, authorization and charge records. Most operators need both, and they are designed to work together.
Should we implement OCPP 1.6 or 2.0.1?
Many chargers in the field still run OCPP 1.6, while OCPP 2.0.1 adds stronger security, richer device management and better support for smart charging and ISO 15118. Most networks plan for both: supporting 1.6 for the existing estate and adopting 2.0.1 for new hardware. We help you set a version strategy that fits your chargers and your roadmap.
What is ISO 15118 Plug & Charge?
ISO 15118 is the standard for communication between the vehicle and the charger. Its Plug & Charge feature lets the vehicle identify itself with a digital certificate, so charging and billing start automatically when the driver plugs in, without a card or app. It works alongside OCPP, which carries that authorization to the central system.
Can you help us settle roaming sessions with partners?
Yes. Roaming settlement depends on CPOs and eMSPs agreeing on tariffs and exchanging accurate Charge Detail Records. We help you design tariff management, CDR processing and reconciliation, including cross-border sessions, so every partner is billed and paid correctly.
