So as everyone knows, the next generation of superchargers are to enable faster charging which everyone is quick to embrace. It is also as some articles have pointed out is going to be the predominate selling point between EVs from competing OEMs. Ok, but there is downside to that, at least for Teslas.
This dawned on me recently when I stopped for lunch and a charge at a newly opened supercharger. I plugged in and by the time I got into the restaurant, got seated and got a menu, I checked my app and my car had only 30 mins before it would be done and I hadn't even placed my order yet. So, to buy myself some time, I bumped the SOC to 90 form 80%, which gave me 10 more minutes.
I felt like I was in a rush to get my food and eat it, so that I could get to my car before it finished charging or face stiff "idling fees". So while fast charging seems great, this in my opinion is one of those "careful what you wish scenarios". Perhaps over the years I have grown accustom (spoiled) to being able to take my times getting something to eat and use the rest room while on a roadtrip. Before anyone says, "....well you could move the car when it was done". Not very practical/feasible when you are traveling on your own and you have a half eaten meal at your table getting cold while you run out to the car, move it and come back in.
Also related to faster charging, I recently learned that it is not just our cars that get updates to improve efficiency, but so do the superchargers. I have notice of late that the charging rate seems a bit faster at chargers I have used in the past. This was confirmed by a Tesla employee. As time has gone by and Tesla learns what these battery packs can handle, they have been little by little "loosening the screws" on the speed at which the SC charges.
