Except for long distance travel using the SC network, all our other charging is done at home. Usually it is set for 50%, 80% for the weekends or when we have more local driving planned for the day. Every time we get back home the Tesla is plugged into our 30a EVSE we got 4 years ago when we got our Leaf. It charges up right away and is ready for the next drive.
We gave up public charging years ago with the Leaf when I realized what the "FREE" electricity we got from the DCFC cost us in time and miles going there, charging, then driving back home. We could spend an hour and get what would only cost of $1 at home. Now in the Tesla and Supercharger, we still only get about $3 of electricity for each hour, less if there is a waiting line like there is in the urban California Superchargers. I do not know for sure, but I suspect that many charging there are local and go to the SC to get free fuel, not thinking of the value of their time. For me, my time, even leisure time, is more valuable than $3 per hour. If you are sitting at the Supercharger just waiting for more electrons you are not properly pre-planning your trips, or you are local and could just charge at home. The exception would be those in appartments or condos that are not able to install an electrical outlet where they park. For these folks they have to just accept that they will waste time at the SC and find something productive to do while there.
Now while on trips, and we do lots of those, the Supercharger Network is very valuable. It is the reason that Tesla does not have any competition in the EV market. Whether an EV has 85 miles range or 249 miles range, they can not be recharged quickly enough to make it practical for long trips like the Tesla is. Plus, anyone using a public DCFC network is paying more for the electricity than they would for GAS and then add all the extra hours the trip takes.
With the Tesla we are able to make these long trips in almost the same amount of time as with a ICE car. Even if the car could go for 8 hours without stopping, we always stop every 1 to 2 hours for potty break and walking around to get the blood flowing in our legs and feet. With the Tesla we do the same, only we stop at a SC, find a restroom, walk around, and get a snack if needed. After 10 to 15 minutes we are ready to go again. If we stay longer it is not to get more electricity, it is just letting the car charge more while we are doing something else. Sometime it is talking to ICE drivers and answering questions about driving an Electric Vehicle.
AS A SIDE NOTE: Does anyone know if Tesla has accumulated the SC data to find out what percentage of charging is from local owners as compared to owners on out of area trips? I would be interested to know that statistic for the "overbusy" California Superchargers. The only wait I have had while on a trip was at the Rancho Cucamonga, CA Supercharger.
