This section dives deeper into the design of critical UI screens for the mobile app, focusing

on user experience and functionality.

• Purpose: This screen allows users to effortlessly initiate a charging session at a

nearby station.

• Location Indicator: Displays the user’s current location or allows manual selection

if needed.

• Nearby Stations: A clear list or map view showcasing nearby charging stations

with real-time availability information (number of available chargers).

• Station Details: Upon tapping a station, users can access details like address,

connector types (J1772, CCS, CHAdeMO), and estimated charging time-based on

vehicle selection.

• Start Charging Button: A prominent and visually clear button to initiate the

charging session at the chosen station (potentially disabled if no charger is available).

• Purpose: This screen enables users to plan their journey and locate charging stations

along the way.

• Origin & Destination Input Fields: Users can enter their starting and ending

points using either text input or location selection on a map.

• Route Options: The app displays different route options with estimated travel

times and charging station suggestions along the way. Users can prioritize routes

based on factors like shortest travel time or fewest charging stops.

• Estimated Charging Time: For each suggested charging stop, the app displays

an estimated charging time based on the user’s selected vehicle.

• Purpose: This screen enables users to easily select their vehicle and configure charging preferences.

• Vehicle Profile Selection: Users can choose their vehicle from a pre-populated

list based on their account information or manually add a new vehicle profile.

• Battery Information: The app displays the user’s vehicle battery capacity and

current charge level, potentially retrieved from the car’s connected services (if

applicable).

• Charging Preferences: Users can set preferred charging speeds (if supported by

the station) or schedule charging sessions for off-peak hours to potentially benefit

from lower electricity rates.

• Search Bar: A prominent and easily accessible search bar allows users to quickly

search for stations, and specific locations, or filter results based on keywords.

• Previous Search History: The app displays a dropdown menu or list showcasing

recent searches, allowing users to easily revisit previously explored locations or

charging stations.

• Purpose: This screen provides an overview of the user’s available payment methods

for charging their electric vehicle (EV) through the app. Users can add, edit, or

delete payment methods from this screen.

• List of Payment Methods: The screen displays a list of the user’s connected

payment methods, such as credit cards, debit cards, or digital wallets (e.g., PayPal,

Google Pay). Each payment method should be visually distinct and easily identifi-

able, potentially using logos or icons.

options to edit card details (for credit/debit cards) or delete the payment method

entirely. Consider using well-understood icons for these actions.

• Purpose: This screen allows users to conveniently access and manage a list of favor-

ited charging stations for quick reference in the future.

• Saved Stations List: The core element is a clear list showcasing the user’s saved

charging stations. This list might display station names, addresses, and potentially

icons indicating connector types (J1772, CCS, CHAdeMO) for quick identification.

• “Add Station” Button: A prominent button allows users to easily add new

charging stations to their saved list, most likely through search or browsing features

within the app.

• Purpose: This screen provides users with vital information and controls while

actively engaged in a charging session.

• Station Information: The screen displays details about the charging station currently in use, such as the station name, address, and distance from the user’s location

• Charging Status: This section showcases critical real-time data about the ongoing

charging session, potentially including:

• Amount of kWh delivered so far

• Remaining charging time estimate

• Current charging power output (kW)

• Session Cost: The app might display the estimated or current cost of the charging

session based on charging rates.

• End Charging Button: A clear button allows users to manually terminate the

charging session if needed.
