Slow chargers at destinations (home, work, hotels, cabins, ski resorts) should be dumb. At most they should take payment directly via contactless or via a shared kiosk in a parking lot, no app or account required. Most Level 2 chargers are pretty dumb. They are not much more than an integrated AC outlet, cable, contractor, GFCI, and optionally a payment terminal.
Fast chargers should be smart. They should report their status and availability, so you (and your in-car nav) know which chargers are working or congested.
The car should be smart, and navigate you to these chargers (with options of course if you have preferred routes, stops, charger brands, etc.). The car knows when to schedule a charge so you will arrive with an optimal battery charge (low) and not spend extra time charging all the way to 100% when it is faster to move on to the next trip segment.
Fast chargers should also take payment either via plug-and-charge that bills a single account linked to your car (ie Ford BlueOval pass), or take tap-to-pay directly on the charger without an app or account requirement. The latter is a requirement of the federal infrastructure funding for EV fast chargers.
Destination chargers are great and can absolutely make EVs a daily convenience for many. But I've taken many road trips in my EV that simply would not have been possible with basic dumb outlets as my only way to charge.
- vel0city 3y agoThat's an interesting idea. Like with pay parking lots, have a central kiosk that you go pay for the parking and it enables the EVSE at the spot. Only a few actual payment terminals needed means it reduces the odds of a failure at any particular spot and reduces the cost. Seems like a good idea. At hotels it could be tied to a room key to charge to the room.
- stetrain 3y agoTesla has actually implemented it in locations where their chargers did not have onboard payment terminals (since Teslas charging at Tesla chargers negotiate this automatically) but were required to add local payment options. https://driveteslacanada.ca/news/tesla-adds-standalone-screens-at-superchargers-in-taiwan/ https://driveteslacanada.ca/news/tesla-adds-standalone-scree...
