EV Charging Experience
Making the search and activation of EV chargers intuitive, fast, and stress-free for drivers on the move.

The challenge
The design focused on presenting only the most essential information in a clear, intuitive way, enabling users to charge their car without distractions.
I did user interviews with EV owners, created personas, mapped the user journeys, with particular attention to the checkout flow: activating the charger, monitoring the charging process, and completing payment, also eliminating painpoints in the flow of registration.

Goals
Charge easily while on the move
Plan trips with optimal charging stops.
Ttransparent pricing and access to cheaper, off-peak charging.
Real-time updates on availability, compatibility, and maintenance.
Pain Points
Arriving at chargers that are occupied or out of order.
Lack of filters for charging speed, or payment methods.
App UX Slow, cluttered, or not tailored for use while driving.
Long registration processes for each app depending of the charger
Needs
Real-time availability with smart filters (speed, plug type, network).
Unified wallet & billing across networks (Twint, Apple Pay, RFID).
Favorites & history for recurring locations.
Predictive suggestions based on habits (e.g. “charge now to avoid peak times”).
Technology Use
Smartphone: iPhone 15 Pro, Apple Watch
Apps: Tesla app, Swisscharge, Plugsurfing, Google Maps, Waze.
Payment Methods: Apple Pay, Twint, EV charging RFID cards
Core Insight
In most EV charger apps, users struggle with too much technical detail and poor UI prioritization.
Outcome
At the time of development of this app in the year 2019 the use cases for payments after a charging session needed to be an expensive custom development, as Paypal and the different banks do not offered options for this use case.
The app was developed in React Native and released for iOS and Android with a different brand and some bugs regarding payment sessions, the project was stoped because some issues with the APIs.
