Redesign eCharge app with UI/UX concept: How and where do I charge my electric vehicles? How long does the battery last? Which board functions will help me? Before development of the app, we surveyed e-mobilists and people who were new to e-vehicles about their driving behavior and handling of electric autos. Via paper prototyping and a UX test, we analyzed how they use the app, what they expect from the charging function, and how they plan their routes. We used these insights for the development and confirmed our impulse to rely on simplicity.
