Scan, pay with UPI, charge.

Our flagship: a UPI-native CSMS with zero-registration, zero-app-download charging. Scroll through one session, from the QR code to the last meter value.

01/04

Scan the QRNo app to download, no account to create. The driver scans the code on the charger.

01Scan the QR
No app to download, no account to create. The driver scans the code on the charger.
02Pay with UPI
Payment happens in the UPI app they already use. The CSMS starts the charger the moment it clears.
03Plug in
The connector moves to Preparing while the vehicle and charger agree to start.
04Charge
Energy flows. Meter values stream to the CSMS and to the driver's screen, live.

What we build

Every layer of charging, built for your network.

Start at the CSMS core and go down layer by layer: chargers, roaming, revenue and drivers, with energy management as an add-on underneath. Each layer answers one simple question.

Layer 01 / 06

What's happening across the network right now?

One live view of every charger, session, site and tenant, with rules that handle the routine work.

Roaming · OCPI 2.2.1

OCPI connects your network with other networks: their drivers charge on your chargers, yours charge on theirs. Here is one roaming charge, step by step.
