E-Loop – EV Charging Station Finder A Design Sprint Story
E-Loop is a mobile app that helps EV owners find charging stations effortlessly. In a fast-paced 3-day Design Sprint, we focused on user research, rapid prototyping, and testing to address key pain points and improve accessibility. This case study highlights my ability to design efficient, user-friendly solutions under tight deadlines.
Challenge
As electric vehicles (EVs) become more mainstream, finding charging stations remains a frustrating challenge for owners. The core pain point? Users often struggle to find stations with available slots nearby, wasting time and energy. Our 3-day design sprint aimed to solve this by creating a simple, intuitive mobile app that lets EV owners easily find nearby charging stations and book slots ahead of time. We had a tight deadline, so the goal was clear: Create a seamless app that makes finding and booking EV charging stations as easy as possible.

Day 1: Understanding and Defining
User Insights:
Through quick user research, we learned that EV owners wanted:
Real-time availability of slots.
The ability to filter by charging speed, distance, and price.
An easy way to book in advance.
Defining the Problem: We summarized it as: How might we help EV owners quickly find charging stations with available slots and book them in a few taps?
Day 2: Ideation and Wireframing
Sketching Ideas: We sketched multiple wireframe ideas for the app’s core functionality:
A map showing nearby stations with real-time availability.
Filters for charging speed, distance, and price.
A simple, clear booking flow.
Wireframes and Icons: We turned our sketches into low-fidelity wireframes and designed custom icons for station types, action buttons, and filters.
Day 3: Prototyping and Testing
Building the Prototype: We created an interactive prototype using Figma, featuring:
A map interface with real-time station availability.
An intuitive booking flow.
User Testing: We tested the prototype with a few users, gathering valuable feedback. Users appreciated the simplicity and ease of booking.
Visual Design
Outcome: Impactful and Intuitive
By the end of the sprint, we had a polished prototype and positive user feedback:
What Users Loved:
“It’s so easy to find available slots and book them in just a few steps!”
“The live updates will be a game-changer. I will always know when a spot is free.”
What We Learned: User feedback validated our design direction, and we identified areas to improve, like adding ratings for stations.

Reflections
This design sprint taught us the power of collaboration, user feedback, and iteration. We quickly validated our concept, refined our designs, and built a solution that was both effective and user-friendly
What’s Next?
The prototype is just the beginning. Next steps include refining the app, adding more features (like payment integration), and testing with a wider user base to ensure we meet the needs of EV owners everywhere.
