The problem

A charging operator needed its own platform: talk to real chargers over the industry protocol, let drivers pay, and give staff a single place to see stations, sessions and faults.

What we built

An OCPP 1.6-J central system that controls chargers directly, an installable driver web app with wallet, reservations and push notifications, and an admin panel for stations, sessions, faults and receipts.

How it works

  1. 1Chargers connect to our central system over OCPP.
  2. 2Drivers fund a wallet by card; each session debits it.
  3. 3Every session produces a numbered receipt.
  4. 4Staff monitor stations and faults; a simulator tests chargers before go-live.

Highlights

  • Talks to real charging hardware
  • Separate staging environment
  • Charger simulator for testing before go-live
