I am trying to plan a trip from the Southern California area through the Southern California desert and the Arizona desert and finally into the Phoenix, AZ area. I see that there is a possible way to make this work using I-8 from the San Diego area to Phoenix. Even given the limited range of say 70 miles on the highway between charges from the various chargers and location of chargers that I see on the PlugShare trip planner. However several of the key charger locations are "Tesla Superchargers". Are these chargers the same as a "Fast Charger"? I have used Level 2 and Fast Chargers but I am not familiar with Tesla's 'Superchargers'. Just wondering if a Kia Soul EV can use these. Without the use of the Tesla Superchargers along the way I am not sure how realistic this idea is either given the amount of desert area between Phoenix and Southern California. On a good/decent battery can I plan on 70 miles all highway?
