After Tesla takes over the world.... (Getty images / rural Alabama) This is what I remember as a kid. Service Station workers wearing a tie.
For the US market, for the AC side on consumer mass-market highway capable EVs/PHEVs, the current standard is J1772. Since Dec 2010, all of them are compatible w/J1772 except Teslas. Model S and beyond come w/a free adapter. Tesla for Model S and beyond in the US use their North American proprietary connector which they use on their wall connectors (Model S/X/3 Wall Connector), mobile connector and (Model S/X/3 Gen 2 Mobile Connector Bundle). Tesla installs and has businesses install the former: Destination Charging | Tesla. My work has a couple of these and some hotels install them. For DC charging: there are 3 plug incompatible standards: SAE Combo flavor of CCS (aka Combo1), CHAdeMO (a world standard) and Tesla's North American connector for Supercharging. And yes, Tesla sells a CHAdeMO adapter. For Europe and some other parts of the world, there's also Mennekes Type 2 for AC charging (where they don't tend to use J1772), Combo2 flavor of CCS (again for Mennekes Type 2 regions) and Tesla uses a different connector in Europe (I believe it's Mennekes Type 2 but with holes that go deeper to accommodate their European Superchargers). EV DC Fast Charging standards – CHAdeMO, CCS, SAE Combo, Tesla Supercharger, etc under DC Fast charging standards – CHAdeMO, CCS, Supercharger, China has some visual aids of the non-Tesla DC connectors I mentioned. In China, there's also a GB/T standard for DC fast charging and apparently another connector for AC charging which looks kinda like Mennekes Type 2 but isn't. I saw this piece last year: Tesla unveils new dual connector charge port design for Model S and Model X | Electrek. To add to the confusion, there are likely some more DC standards coming (e.g. Tesla Megacharger and whatever Porsche's doing for 800 volt DC fast charging). Oh, and I have brought my Leaf to gas stations to clean my windows/windshields and to use their air compressors. About 2 weeks ago, I passed the 5 year mark of having a Leaf being my primary car. My Prius is now hardly ever driven. Prius is at ~81K miles now. Current '13 Leaf is past 57.5K miles. It came with under 24K miles on it as I bought it used. I put a bit under 24K on my leased former '13 Leaf. That one had a CHAdeMO inlet. My current one doesn't.
I'd sure like to know what kind of window cleaner they used back in those days! A couple of sprays, and a few wipes with a paper towel, and the windshield on our old Pontiac was spotless! (I can still remember that smell. ) Plus, they checked the oil, checked the radiator, and sometimes put air in the tires too. All that for about .29 cents per gallon? And free maps, too. And they gave out "Green Stamps" that you stick in a book. After you get so many stamps, you get some kind of free merchandise. I believe this is just like my parent's 1958 Pontiac. Same color. Mom drove it. The gas station guys could never find the fuel door... it was inside the tail light. And my dad drove the 1957 red Ford wagon. Beautiful!
I recall looking through my Dad's pay statements; when he retired around 1970 his monthly take-home was five something..., hundred that is.
My Honda scrambler had a 1.5 gal tank I and I filled it for $0.25 at the Deep Rock station during the gas wars in 1971. Took a family vacation a few years later and I remember Dad being upset at an out of the way station having the audacity to charge $0.65 per gallon.
I was far from being able to drive, but I remember that fuel fill location. But he was able to buy more with his income back then.
