Qerra OS
Driver and user interface
Simple charging for users. Full control for the business.
Charging should not require training, instructions or technical knowledge. Drivers and end users expect the process to be simple, fast and predictable. Qerra OS delivers a quick, intuitive experience while power management, access and priorities stay in the background.
What users see and do
The interface is built for fast, easy use. It is focused on day-to-day needs and exposes only what matters:
- 01Fast identification via RFID card, mobile app or company profile
- 02One-tap start and stop of the charging session
- 03Clear charging status and expected time to completion
No complex menus, technical settings or unnecessary steps.
What the system manages automatically
To avoid confusion and mistakes, we have removed complex settings from the user interface. Users focus on charging; Qerra OS handles the rest:
- 01Management of available power
- 02Compliance with site and grid limits
- 03Fleet priorities
- 04Power distribution across active charging sessions
Users get a predictable experience while the system stays protected from errors.
Controlled access without unnecessary complexity
Each user gets access according to the organisation's defined rules. Qerra OS applies those rules automatically, without manual intervention. This guarantees:
- 01Fair access to charging infrastructure for all users
- 02Compliance with energy limits
- 03Automatic prioritisation when needed
- 04Consistent rules and user experience across every location
Users see a simple charging process while the system enforces the rules in the background.
An interface built for everyday use
The interface is designed to be easy to use from the very first charging session. To achieve that, it follows three core principles:
- 01Clarity — the user always knows what is happening and what the charging status is.
- 02Predictability — charging always works the same way regardless of site or location.
- 03Unobtrusiveness — the interface supports the process without interrupting it.
Why this matters for the business
When charging is simple for users, it brings real benefits to your business:
- 01Fewer interrupted or failed charging sessions
- 02Fewer calls to the support team
- 03Higher system utilisation
- 04Less friction between users and operations teams
When charging is simple, it becomes routine — not a problem.
The driver and user interface is not built to impress. It is built to be easy to use every day, while Qerra OS works quietly and reliably in the background.
Simple for users. Predictable for operations. Reliable for the business.
