Our initial research focused on getting a good understanding of habits and existing routines for EV owners, especially those who regularly used a home charger. This helped us form a view of their motivations, frustrations, needs and wants when it comes to their home-charging experience. We also talked to several potential EV owners so that we could also understand their expectations around the future of this industry, and what it would take for them to switch.
We found that, when it comes to home-charging, the level of involvement from individuals varies in terms of scheduling their charging sessions and tracing the cost of charging. Our research revealed that certain users preferred to set their car to charge at very specific hours to save them money, sometimes determined by a late-night energy tariff. Other users were intimidated by the details required for creating schedules according to times and tariffs, and so would prefer to simply arrange for their car to be fully charged and ready to drive in the morning.

With all of this in mind, it became clear to us that an app aimed at these customers would need to provide two different approaches to scheduling charging sessions. We collated and mapped our findings into current and ideal user journeys, and used them to inform the design of our initial wireframes (low fidelity, skeleton-style screens). We turned these early wireframes into clickable prototypes and tested the two approaches to scheduling, as well as the layout of the app, with target customers.
