    Behind every working charging infrastructure stands thorough analysis

    Most organisations we work with have the same concerns — fleet readiness, access control, cost allocation, the scale of construction work.

    There is no universal solution. The right approach depends on the site, the fleet and the needs of the business.

    That's why every project starts with analysis. Only then do we design a solution that provides charging infrastructure working effectively today and ready to grow with the business in the future.

    01

    Business as the starting point

    System design starts from how your business works — schedules, fleet, growth plans. Charging infrastructure is designed around them.

    02

    Energy before hardware

    Charging is managed as a controlled electrical load, not as individual sessions.

    03

    Designed-in growth from day one

    Growth is planned into the system from the start, so it doesn't need to be added later.

    04

    Long-term responsibility

    Qerra remains committed to the operation and stability of the charging infrastructure over time.

    How we work

    Before we choose equipment, we analyse how the business works and what its real constraints are.

    01

    Analysis

    We start with analysis of the business. Grid capacity, operational schedules, growth plans. The system is designed around all these factors, not the other way around.

    02

    System design

    We design the infrastructure, chargers and management logic as a single whole. Every element is aligned with the others so they work effectively together.

    03

    Build & commissioning

    We build and test the system under real conditions. It matters not just that it is installed, but that it works reliably and stably.

    04

    Qerra Care

    Our commitment doesn't end at commissioning. Qerra Care provides continuous monitoring, preventive maintenance and guaranteed response times.

    Standalone service · Expertise

    Strategic fleet electrification consulting

    A paid engineering and organisational engagement for companies that need an audit, a TCO model, a grant strategy or team readiness — before or independent of building infrastructure with us.

    It is not part of the standard pre-project conversation. It is purchased separately and ends with a management document: fleet readiness, how drivers will charge, the business case and applicable funding sources.

    Designed for

    • Companies in the early stages of electrification
    • Organisations with constrained grid capacity on site
    • Teams without in-house expertise for the EV transition

    01

    Fleet & routes

    Which vehicles are ready for electrification, daily mileage, battery needs and total cost of ownership.

    02

    Drivers & behaviour

    Driver attitudes, home-charging feasibility assessment, training and change management.

    03

    Business case & strategy

    Phased electrification plan, risks, KPIs and growth scenarios — before any equipment is chosen.

    04

    Funding & regulation

    EU and national grants, permitting and support throughout the application process.

    Every site is different

    There is no universal solution. Different businesses have different needs.

    We don't sell software. We manage systems.

    Qerra OS is a proprietary platform that unifies the management of charging infrastructure, energy, the fleet, employee mobility and roaming access in one centralised system — regardless of hardware.

    • Distributes power in real time
    • Manages access according to your business rules
    • Tracks every session — on-site, at home, at a public station — and consolidates it into one report

    Qerra OS is the tool through which we assume real operational responsibility for every system we design, deploy and manage. The focus is on reliability, control and long-term sustainability.
