The initial goal of ChargeLab 2.0 was to create a seamless, distraction-free EV charging experience by integrating navigation, real-time charger updates, and payments into a single app. Early concepts focused on effortless on-the-go charging adjustments and eliminating the need for app-switching while driving.
Some initial ideas included a one-tap “Add Charger” button to quickly update routes and smart filtering options for charger availability, price, and wait times. At this stage, dynamic charger status indicators (adjusting opacity instead of color) were introduced to help drivers quickly distinguish available chargers at a glance.
Early sketches also explored gesture-based controls for quick rerouting and a predictive charging assistant that suggested stops based on user preferences and real-time conditions.
Ultimately, real-time charger updates and ChargerMatch’s personalized recommendations became the foundation of ChargeLab 2.0’s redesign, ensuring drivers could plan, charge, and pay in one streamlined experience.
User Flows
This User Flow was designed to streamline the process of finding, selecting, and navigating to a charger while minimizing distractions. The goal was to ensure quick access to real-time charger data while keeping interactions fast and intuitive for drivers on the go.
To reduce friction, we eliminated unnecessary steps by integrating charger availability, route adjustments, and payment options into a single flow. Users can set preferences, get smart recommendations, and start navigation with minimal taps, allowing them to focus on the road instead of managing multiple apps.
Wireframes
The wireframes for ChargeLab 2.0 focused on creating a quick, intuitive way for users to locate and access chargers without unnecessary complexity. Early designs prioritized simplified navigation, ensuring that drivers could view nearby charging stations, real-time availability, and estimated wait times at a glance.
To enhance usability, I limited the number of on-screen elements to only the most critical details, preventing information overload. Charger selection was streamlined to offer smart recommendations based on user preferences, with one-tap navigation and payment integration. These wireframes laid the foundation for a seamless, distraction-free charging experience, ensuring drivers could make informed decisions in seconds.
