EM Lite came to us to build the app for their new home EV chargepoint. The chargepoint has no screen, so everything happens in the app, for two very different users: installers, who configure and test it against the home’s electrics, and homeowners, who then control it. We worked with EM Lite’s IT and product teams and with the third-party suppliers behind parts of the system.
One app, two jobs: installers commission EM Lite’s screenless Veva chargepoint, and homeowners control it from anywhere in the world.
01
The start
A chargepoint with no screen, so the app had to be right
02
The journey
Four problems we had to solve
Connectivity that looks after itself
Whenever the chargepoint is off the WiFi, the app walks the user through connecting to it directly over a local hotspot and setting it up again, with no installer visit and no support call.
An installation guide that installers follow
Installers are taken step by step through commissioning, setting and testing the settings against the chargepoint and the home electrical setup.
Simple user management
Households set up different cars and charging cycles, with several users seeing the data relevant to them and their vehicle across one or more chargepoints.
Working with the product team
Close integration with EM Lite’s teams and prototype hardware kept everyone moving without interruption.
03
The result
Every edge case handled, without the usability suffering
A deep analysis of the system turned up multiple dependencies and use cases, so we built a carefully constructed product plan and tested it with users. EM Lite called the app indispensable to the product’s launch.
- Manage charging schedules
- Multiple users and cars on one account
- Cost tracking and spend analysis
- Home WiFi configuration from the app
- Control the chargepoint from anywhere in the world
- Installer mode and customer mode in one app
