EV ChargePass – Mobile


UX Manager, Lead, & Contributor

The EV Chargepass mobile app helps businesses manage expenses, cards, credit accounts, and bill payments, across many accounts in the EV purchase category space. The technology and data powering this EV app is sourced from many separate systems. The EV ChargePass mobile app offers many common mapping / location tools, but many unique tools for drivers of EV vehicles, or managers of fleets that include EV vehicles. Over time, there are different brands and ports of this app, with different levels of integration over time. The PlugSurfing.co.uk integration is the version as of early 2025. In the later versions of this app, it grew to be more integral into Google Maps and provided more useful Pricing & Charging data. The mobile app experience is most suited for Drivers / Employees but also has support for administrators. The Driven app itself is currently a home-grown, stand-alone app, with little to no customizations for other business partners (subject to change).

Challenges:

  • How might the app communicate a driver’s ability to charge their vehicle, as quickly and effortlessly as possible?
  • How can the driver profile be more intuitive, so the app usage can be more touch-go vs continuous maintenance?
  • How should the app communicate costs and wait times, when data is often sparse or unreliable?
  • What app experience should be promoted for non-registered and registered users?
  • What degree of onboarding can we put pre-emptively onto the user before they arrive on the Home/Dashboard?
  • How can we improve the charging experience, when an EV driver is off grid / out of network?
  • What ways of displaying content would be most effective, to get an EV driver to consider getting one of our credit cards?
  • How might a non-customer get pre-approved for more credit and more products?
  • How might a user become more engaged with the app in ways that are not only charging the vehicle?
  • How might a driver prefer to stay/remain in the app instead of leaving/going to Google Maps?
