Main Image 3

EV Charger is a multi-functional iOS App.


The Client was looking for a mobile app that could be used as a switch for the Charging Station of an Electronic Vehicle. The app had to also include a functionality that would allow users to track their electricity consumption. There were a number of challenges that were hindering the client’s progress. They required assistance to solve the following issues:

  • How to communicate with the charging station
  • How to allow users to access the charging station
  • How to dynamically change the gateways for the charging stations
  • Authorize users credit card with some payment gateway

Rolustech sat down for a number of meetings with the client to properly understand their requirements and started working on a solution that would satisfy their needs. Our developers devised a mobile app that users could use to charge their electronic vehicles through a designated charging station. The mobile app also included information on the charging station capacity and tracked the user’s consumption to calculate periodic billing and cost estimates.

The app features and functionalities implemented by Rolustech are detailed below:

  • Login
  • Signup
  • Start/Stop Charging Station
  • Charging Status
  • Setting/Configuration:
    • User details
    • Charging Station Details (Authorization)
    • Credit Card Verification
  • Billing/Charts
    • Daily Consumption
    • Weekly Consumption

The client was thrilled with the prompt and timely project delivery and the numerous features recommended by Rolustech to improve the user experience and usability. The client was particularly delighted with the updated out of the box UI design and has continued to collaborate in a number of projects ever since.
