Glad to see you're entering into talking about EV's. I've had my Ioniq 5 for almost two years, have made about 5 or 6 long road trips, plus I have an Enphase Solar Panels with Battery for two years as well,
Last year I used EA for a trip to Florida in our Tesla model 3. At that time, the rates were MUCH cheaper as in many areas I could pay per minute vs per kWh. It worked well but the manually having to precondition by routing to a Tesla charger and the re-route was a pain. I am glad to see more infrastructure going in place.
