(Intro)

An intuitive and delightful app that connects EV users with on-demand charging services while incorporating predictive technology to anticipate user needs, and enhance convenience.

Reefilla is the first mobile predictive EV charging delivery service thought for drivers. The startup was on the lookout for a design for their first Proof of Concept (PoC) and create from scratch the app for Reefilla customers considering all the steps of the service journey and the app service integrations.

The redesigned application received positive feedback from both business and users, who appreciated the improved usability and modern look. Key metrics such as user engagement and satisfaction saw significant improvements. The project not only revitalized the digital presence of Banca Popolare di Sondrio but also set a new standard for user experience in the banking sector.

PROCESS

From the hardware engineering solution to the development of the digital user experience.

The app's design was meticulously crafted based on comprehensive user research and service optimization studies. By conducting interviews with both EV owners and operators, the team gained valuable insights into their specific pain points and behaviors regarding charging needs and mobility. This research revealed critical issues such as the frustration of locating charging stations and the necessity for accurate, real-time availability predictions. These insights were integral to simplifying the customer journey, reducing user touchpoints, and easing user effort. The iterative design process included user journeys, wireframing and prototyping, ensuring that the final product was user-centric and efficient.

simplified navigation, and relaxing look & feel

The design focused on simplifying navigation to reduce user effort and streamline the charging process. The app is designed to be accessible through a swipeable menu. Its three sections: dashboard, map and profile, each play a distinct role in providing a complete service experience. The dashboard has been kept very minimal with big visuals and one button which includes the status of the service.

The map section provides users with the available service locations. The profile section includes the user’s account, history and payment methods. The app has been designed to make it easy for the user to access the information they need in a few simple taps.

screens, flow maps & design system

The final solution encompassed around 50 screens, each meticulously designed to enhance the user experience. The screens were crafted to be intuitive and user-friendly, ensuring that users could navigate the app effortlessly.

A comprehensive Figma design system with interactive prototypes was developed. This system provided a cohesive framework for the app's design, allowing for consistent and efficient updates. The interactive prototypes facilitated user testing and feedback, ensuring that the design met user needs.

The app displays graphics and text indicating current charging level, confirmation of charging, and options for scheduling future charges.

Real-Time Availability Predictions

One of the key features integrated into the app was real-time tailored charging predictions based on the current battery range and users’ habits. This feature addressed the frustration users experienced when booking a charging session, providing accurate and bottom-up service that makes it easy and effortless for ev users to charge their vehicles.

scalable service

The objective was to create a scalable app allowing room for future service expansion. The solution could easily handle an increasing number of users and locations, while leaving room for growth and expansion in the future.

The app was designed to be future-proof and scalable, so that it could accommodate the increasing demand of services. We also set up the architecture to be flexible, so that additional features can be added with ease.
