05What we build
Six layers
We build every layer of a charging business: the CSMS core, charger connectivity, roaming, revenue and the apps drivers and operators use, with grid and energy management as an add-on. Take the layers you need.
Layer 01 / 06
One live view of every charger, session, site and tenant, with rules that handle the routine work.
Included
Every module ships on its own, or together as one CSMS.
Book a demo06Regulation
US · UK · EU · California · India
Public charging is now regulated on uptime, payment and open data. We build what each market asks for into your CSMS from the start, so audits find what they expect.
The rule
>97%
Average annual uptime for every NEVI-funded charging port, reported each quarter with session, energy and outage data. Contactless card payment, no membership required.

What we build in
07Roaming
OCPI 2.2.1
Over OCPI, partner drivers charge on your chargers and your drivers charge on theirs. We build the CPO side, the eMSP side, or both. Below are the six exchanges behind a single roaming session.

Step 01 / 06
Your CSMS publishes locations and live availability. Partner apps put your chargers on their map.
{ "id": "LOC-001", "evses": [{ "uid": "EVSE-1", "status": "AVAILABLE", "connectors": [{ "standard": "IEC_62196_T2_COMBO" }] }] }
Run as a CPO, an eMSP, or both. We build each side of the link.
You run the chargers. Share them with every partner so their drivers can charge on your network.
Sends:Locations · Tariffs · Sessions · CDRs
You own the driver relationship. Let your drivers charge on every partner network.
Sends:Tokens · Commands
Everything a live roaming link depends on, beyond the basic flow.

Tell us which networks or hubs you plan to connect. We scope the OCPI work for the CPO side, the eMSP side, or both.
08App-less charging
Card worldwide · UPI in India
Drivers scan the QR on the charger and pay by card in the browser, with no account and no download: the ad hoc payment EU and US rules now ask for. In India the same flow runs on UPI. One session, from QR code to final meter value.
Scan the QRNo app to download, no account to create. The driver scans the code on the charger.
