Where can I charge?
Make station discovery and route planning part of the same journey.
EV CHARGING / FOUR-WEEK CONCEPT STUDY
Know where to charge.
Know what happens next.
A connected charging concept that helps drivers find a station, understand charging progress, and plan their next move.

THE CONCEPT / BULOO
One experience.
Three moments of confidence.
Set up the vehicle. Check charging progress. Find the next station.
Original interface designs and interaction prototypes.
01 / THE CHALLENGE
The uncertainty extends beyond finding a plug.
The study explored Level 2 charging: locating the station, interpreting instructions, connecting the car, and confirming that charging had started. Research surfaced unclear locations, inconsistent indicators, limited power management, and range anxiety.
Has charging started?
Give charging status and remaining time a clear place in the interface.
What happens next?
Explore how vehicle context and trip planning could support the next decision.
02 / RESEARCH & MY CONTRIBUTION
Observe the charging experience in context.
I conducted research, organized findings, and translated them into interaction and interface concepts. Working closely with an EV owner, I used interviews, contextual observation, and testing of the existing charging experience. First- and third-person recordings helped reveal missing feedback across the task sequence.
RESEARCH → DESIGN DIRECTION
Make system status visible at each transition.
The findings connected uncertainty at the physical charger with a broader need for understandable location, connection, and progress feedback. I used affinity mapping and usability principles to organize these problems before designing the concept.

WHY THESE FEATURES
Trace the concept back to the research.
Observed problemDesign responseQuestion to validate
Unclear station locationNearby discovery and route planningCan a driver choose and reach a suitable station?
Inconsistent connection and status feedbackA shared view of charging state and time remainingCan the driver tell whether charging is active?
Range anxiety and limited power managementVehicle context and planning conceptsAre estimates understandable and credible with real data?
Design rationale reconstructed from the original study. These questions are proposed evaluation criteria, rather than completed tests of the new interface.
03 / THE DESIGN RESPONSE
Connect discovery, status, and planning.
I developed a high-fidelity concept spanning profile setup, a charging dashboard, and station discovery. Each part responds to a different point of uncertainty in the journey.
DESIGN DECISION 01
Start with the driver’s vehicle.
Profile setup captures vehicle information to establish context for the experience. The flow moves from sign-in to vehicle selection before the charging dashboard.
DESIGN DECISION 02
Put charging progress in one place.
The dashboard brings charging status and remaining time into a shared view. A clear hierarchy is intended to help drivers check progress and decide what to do next without piecing together scattered indicators.
DESIGN DECISION 03
Carry discovery through to the next step.
Nearby station discovery connects to station details, booking, and route planning. These interactions explore continuity between finding a charger and getting there; booking and availability would need integration with real infrastructure.
04 / OUTCOME & REFLECTION
A coherent prototype—and clear questions to validate.
The output was a high-fidelity concept developed during a four-week sprint. The work connects research findings to a full charging journey; it does not establish the effectiveness of the proposed interface through post-launch results.
Can drivers read the status?
Test whether people can explain the charging state and remaining time from the dashboard.
Can they find a suitable station?
Validate station selection and route planning with realistic availability and compatibility data.
Can they rely on the estimate?
Trip estimation and booking require validation against real vehicle and charging-network data.
