EV charging stations aren’t just the gas stations of the future. They’re also travel lodges of the future. People might spend significant time at these stations while waiting for their vehicles to charge. Not all EV charging stations are built the same, and the differences matter more for extended visits. It’s critical to create the right user experience, which means considering the following:
Prioritize Ease of Use
Early adopters have already had EVs for years, and now the early majority is starting to embrace electric vehicles. Social reasons for going electric are even encouraging some people who typically don’t adopt technology, especially quickly. As a result, new users of all ages and comfort levels will be interacting with EV charging station displays.
To accommodate a diverse user base, an EV charging station display must be user-friendly and intuitive. Simple screens should provide clear instructions. Touch screens should enable easy navigation. There must be convenient payment options and a clear path to payment.
Users want to know where they are in the charging process and take control of the charging experience as much as possible. Some users prefer to monitor and manage the experience via a mobile app or the in-vehicle interface, so the EVSE must be compatible with other technologies. Diagnostic information, troubleshooting workflows and live support help guide the user to a satisfying experience.
Ensure High Visibility
The EV charging station display will likely be outside, requiring it to be visible in all conditions. It will need the right type of screen to make the charging status visible to the user. When designing an EVSE, it can be helpful to generate code and test it in various real-world scenarios—including sun, shade, partial light and full darkness.
Performance Matters
An EVSE has to offer flexible charging speeds to accommodate different types of EVs as well as user preferences. Then there’s the performance of the EV charging station display itself. When the user wants to modify the charging performance, the interface needs to be responsive enough to make that happen. GUI code that has been optimized for the display hardware makes graphics perform more smoothly. Testing that code on production-intent hardware ensures that the display is adequately responsive to touch.
Inform and Entertain
The U.S. Department of Transportation reports that a fully electric vehicle might take 4-10 hours to gain a full charge from Level 2 charging. This speed makes it more suitable for locations where the driver spends significant time, like home or the workplace. DC Fast Charging (DCFC) is more ideal for high-traffic areas and road trip stops. DCFC might get an electric vehicle to an 80% charge in just 20 minutes to one hour.
In any case, drivers and passengers often have time to kill at the charging station. OTA updates enable a variety of informational and entertaining content. Drivers and passengers may wish to play audio and video without using battery power from their vehicles or devices. Alternatively, users might want quick information about area restaurants, lodging or entertainment.
The EVSE display might also show stats and graphics that gamify the experience. Guest books and driver networks inspire engagement. They also give drivers additional reasons to choose one charging station over another. Capturing a user base also creates opportunities to sell ads, including offers for nearby businesses.
Choose the Right Hardware
Selecting versatile hardware will give the EV charging station greater compatibility and connectivity. The hardware has to be able to support the graphical features of the GUI and run at top performance. At the same time, identifying favorable target hardware goes a long way toward controlling costs.
