ChargeFlow app

01 | The Challenge

Finding a charging station does not necessarily mean finding one that meets a driver's needs.

A station may be occupied, incompatible with the vehicle, too slow, or more expensive than expected. Drivers often need to make decisions without having reliable information about these conditions.

Design question: How might we help EV drivers select a suitable charging station with greater confidence and less uncertainty?

02 | Research and Discovery

ChargeFlow's initial design direction draws on secondary research about public EV charging experiences.

The research highlights recurring usability issues involving charger discovery, operational availability, payment processes, and support.

Four priorities informed the design:

• Compatibility before commitment

• Clear and appropriately qualified availability information

• Transparent pricing

• Alternative actions when a charging plan fails

These insights are drawn from published research, not original ChargeFlow user interviews.

03 | Understanding the Users

Two illustrative personas guided the concept.

Nadia — The Urban Commuter

Nadia needs a convenient charging point near her daily destinations. Her priorities are minimal detours, clear pricing and reliable availability information.

Leo — The Long-Distance Traveller

Leo needs dependable fast-charging stations along longer journeys. His priorities include charging speed, reservation conditions and alternative stations when plans change.

These personas represent design hypotheses for future validation.
