Challenge
Introducing the FLO Ultra, our first 320kW fast charger, required an innovative approach to demonstrate its groundbreaking features. At Distributech in San Diego, we faced the task of showcasing a next-generation EV charging solution that would stand out in a competitive technological landscape.
It also meant designing for genuinely new territory: an interface that had to work outdoors, year-round, through heat, cold, rain, sun, and darkness. It had to be one system, white-labeled across partners, chargers, and screen sizes, never just one screen. And no rig or app existed to build any of this on, so we had to build our own hardware tools and the apps to design, test, and demo with them.
Approach
I developed a web-based prototype that transformed our demo unit into an interactive platform. By integrating controls for the charger's advanced features, including dynamic lighting, audio feedback, and motorized cable management, we created more than just a display. With a VinFast vehicle on-site, we offered convention attendees a tangible glimpse into the future of electric vehicle charging.
That demo unit didn't stay a marketing tool for long. I evolved it into a proper design tool: the same rig and software we used on the show floor became how the team iterated on the interface, tested new layouts, and demoed upcoming features long after Distributech ended.
Results
The interactive demonstration at Distributech generated significant excitement around the FLO Ultra. Convention attendees were the first to experience our innovative charger, getting hands-on with technology that represents a significant leap forward in EV charging infrastructure.
What started as a single charger became a full family: one interface system now powers every unit in the Ultra lineup, adapting across partners and screen sizes without starting from scratch each time.
Lessons
Developing this interactive prototype revealed the power of experiential technology demonstrations. What began as a marketing tool evolved into a critical platform for design iteration and user experience testing. The project reinforced the importance of creating technology that isn't just functional, but truly engaging, and that the tools you build to launch a product are often worth as much as the product itself. I feel fortunate to have been part of a team that pushes the boundaries of innovation in electric vehicle charging.
