EV Charging Control App
A companion app for a smart charging box that takes the place of a standard outlet
The client makes a charging box for electric vehicles that is installed in place of a standard electrical outlet, giving the owner control over charging time, duration and energy use. Our team developed the mobile app that goes with it: owners register their boxes, set each box's details and power limit, and see every charging session with the energy it used.

The product
What it does, and for whom
A charging box is only as useful as the information around it. The app keeps a list of the owner's boxes, adds a new one by scanning its code, and records each charging session with its start and end time, the energy charged and the box it ran on. Charging data is synced with the server, and the owner can let the sync carry on in the background.
Scope The charging box, its electronics and firmware are the client's. Our work was the mobile app. To keep the client confidential, the screens on this page are recreated from the delivered app with neutral naming and example data.
