Overview
EV drivers often face stress caused by incompatible adapters, fragmented public networks, and high adapter costs. These barriers made long distance travel unpredictable and created friction for both individual drivers and fleet managers.
I designed a mobile rental experience that helps drivers easily find, rent, and return charging adapters. The goal was to make EV charging as simple and reliable as filling a gas tank.
What I did
I created over 40+ wireframes and flows for discovery, rental, and return journeys. I built an accessible design system for mobile and web, conducted usability testing to identify friction points, and collaborated with 3 engineers to align feasibility and streamline handoff.
The project lasted 8 weeks with a cross-functional team of 2 designers, 2 researchers, and 3 engineers.
The Challenge
EV drivers needed a way to locate compatible adapters quickly and feel confident that their reservation and return process would work without hassle.
How might we help drivers easily locate compatible EV adapters to reduce charging anxiety?
Key Design Highlights
The new experience introduced an end-to-end rental flow designed around trust, clarity, and speed.
Rent or Reserve Adapters
A clear rental flow that let users book an adapter on demand or reserve one ahead of time with upfront payment to guarantee availability. This reduced uncertainty and increased trust in the system.
Returns
A contactless drop-off flow that allowed users to return adapters at any locker and receive automated confirmation once complete. This streamlined the experience and made returns feel effortless and reliable.
Impact
Reflection
EVALV showed me how accessible design builds trust in new product spaces. Usability testing revealed that uncertainty about availability or confirmation was the biggest source of stress. Small changes, such as upfront payments and visible confirmations, made the experience feel reliable.
Creating a WCAG-compliant design system early also made consistency easier across mobile and web. The main challenge was balancing speed with scope and shipping an MVP meant limiting advanced features like adapter filters or fleet dashboards.
If I had more time, I would run field testing with drivers on trips, refine manager flows, and study long-term adoption. This project reinforced that reliability and clarity are the foundation of user confidence.
