Just took a trip from Bay Area to Los Angeles (and back) with my Model S and exclusively used the supercharger stations. Here are my high level comments for those looking for practical feedback (vs. hypothetical location info - which I appreciate too :)
Process: You pull up (need to make sure your car charging port is as close as possible to charging cord as they are generally not very long), get out of your car, pull the Tesla Supercharger out, push the button at the end of the charger (similar looking to your own home/mobile charger input) and your charge port opens, and you stick it in.
- I'd recommend that Tesla formally creates some etiquette and education around the superchargers. I came across multiple owners who were charging their batteries to the very top (100% full) which resulted in longer than normal waits at Harris Ranch (more on this below). Other than that the process is easy and these stations are GAME CHANGERS imo. There needs to be more education on how the supercharger is meant to be a quick source of 150 mile infusions to owners batteries, b/c the top end (full charge) requires a LOT more charge time and from what I experienced with other owners (who wanted to fully "top off") it resulted in folks spending 1+ hours clogging up chargers.
- Tejon - this is by far the best station (also the model photo on Tesla's supercharger page) b/c there are 6 spots (only 4 operational today) covered by solar panels; and within 300 yards there are (Chipotle, In-N-Out, Starbucks, convenience store and other food options). These appear to all be 90kwh output chargers too - this is a BIG plus.
- Harris Ranch - this is currently a bottleneck for north / south trips as there is only 1 charging port. On my way down I had to only wait 20 minutes but I was lucky as right behind me another two model s vehicles arrived (presumably the last car there had to wait approximately 1.5 hours longer than if there was no line).
- Gilroy - the location of these is great (behind In-N-Out / Sony outlet store; 100's of outlet stores and other food within a thousand yards) however it appears only 2 of the 4 charging stations were of the 90kwh variety, the others were apparently 45kwh.
- Folsom - when I was here only 1 station was operational however they were in the process of installing 3 more. Similar to Gilroy, these are at the outlet mall just off highway 50 (on the way to South Lake Tahoe) with plenty of shopping & food options within a short walk.
Overall I'm extremely proud to be a Tesla Model S owner, Tesla as a company is pushing the envelope in so many ways and these supercharger stations are a prime example of it. The fact that I could drive nearly 400 miles each way (in luxury & performance) in nearly the same timeframe a ICE vehicle can make it is incredible. Yes there are LOTS of things to work out and even little items on my car that need to be tweaked (ie my passenger side mirror is not operational :( but this company is going in the right direction and helping push a revolution to more efficient, cleaner and the most enjoyable driving experience on the road. Thank you!
