Don't know much about them, but saw several Rivians plugged into charge stations at Oakland airport yesterday, as we walked to the BART connector. We were just surprised to see so many. Didn't stop, and couldn't tell you if they were Tesla chargers.
A quick check on Plugshare shows many charge stations at the Oakland airport but no chargers (AC charge stations are often incorrectly called chargers).Didn't stop, and couldn't tell you if they were Tesla charger
Charge stations or chargers, who gives a hoot if I want to charge my EV?A quick check on Plugshare shows many charge stations at the Oakland airport but no chargers (AC charge stations are often incorrectly called chargers).
They are J-1772 charge stations. Use them on anything regardless of make, as they use the charger inside the vehicle which will normally accept any AC voltage from 90 to 250 VAC in. EV cars usually have 12KW AC chargers (both of mine), so it will take hours to go from a low charge to a high charge on an 80 KWH battery, even with 240 VAC. Days with 120 VAC--which will work at the airport for those travelling.
But the Oakland Airport uses 3.3 KW, 240 VAC charge stations. Very slow. Only double of what a 120 VAC outlet will do. But this will work great for those travelling for a few days or longer. No fines when fully charged up, which makes sense at an airport. Free to use no matter what after paying for the $24.00 per day parking.
In this case, Tesla needs the adapter. My Chevy Bolt does NOT. But it's a cheap adapter just so it fits, doesn't change anything.
In 2018, when I purchased my Tesla. it came with this adapter and many more for various AC outlets. AFAIK, Tesla no longer does, they now try too hard to keep the price of the car down.
At the Oakland Airport, you pay for expensive parking. The charge comes with the deal.
BTW, I have even seen Class B RV ICE vehicles using a J-1772 for house power. They have an adapter for 14-50R which you can use with a 30-amp adapter for whatever needed.
So you can even power up your RVs with J-1772 if you can find the room. But you will probably want more than 3.3 KW. Some go as high as 18KW, even higher than 12KW. Such as the 70-amps here (17 KW).
The capacity of these J-1772 charge stations very like crazy. But plug in a 12KW EV into a 3KW charger, no problem. A "Control Pilot" from the charge stations forces the EV charger to go down to whatever the charge station can handle. So my 12KW charger than becomes a 3.3 KW charger even at 240 VAC.

It depends if you want to charge up in 15 minutes instead of 15 hours.Charge stations or chargers, who gives a hoot if I want to charge my EV?
Why not call them slow charge or fast charge? I'm a EE, so understand the difference, but will the average Joe know or care?It depends if you want to charge up in 15 minutes instead of 15 hours.
No such thing as a fast AC charge. DCFCs go direct to the battery, bypassing the charger inside the vehicle and perhaps a 250KW charge instead of (as at the Oakland Airport) 3.3 KW.
So many will "give a hoot".

I knew you would know the difference, that why I was a bit more technical in that message.Why not call them slow charge or fast charge? I'm a EE, so understand the difference, but will the average Joe know or care?
With AC chargers the onboard charger is used. AC charging is L1 (120 volt) and L2 (240 volt).Why not call them slow charge or fast charge? I'm a EE, so understand the difference, but will the average Joe know or care?
What would you call it when the J-1772 is NOT being used to charge anything at all?Why not call them slow charge or fast charge?
Are those two different guys, or the same guy with two different names?... I like to use the correct names. . . .but Confucious would agree with me:
"The beginning of wisdom is to call things by their proper name.” ― Confucius
That's really the accepted correct name for such stuff, but I don't like calling it such because it doesn't exactly specify what the equipment is, such as a "charge station".EVSE’s or Electric vehicle supply equipment.
I was curious about the cost, and read this on Chargepoint's site:At the Oakland Airport, you pay for expensive parking. The charge comes with the deal.
Were they all being used when you went by them?I wondered about the folks who wanted/needed a charge, but couldn't because available stations were being hogged by folks who'd flown out of town for a few days and who's EV had already fully charged.
I wasn't paying a lot of attention, more concerned about making it to the BART connector with my still-healing stiff and painful knee; Chris kept having to stop and wait for me.Were they all being used when you went by them?
Some places installed there EV charge stations when there was a lot less EVs on the road than today. Back then, they were rarely used. Some of these places never added any and now are often all busy all day and sometimes all night long (some Reno casinos on a Friday night for an example).

I wonder where the term "EVSE" first came from. I have heard it many years ago and thought it was a rather stupid term to use since then.

My Chevy Bolt makes parking very easy. The backup camera automatically switches from front to rear as I am parking. Back in or head in park perfectly every time.This is aimed at a public that has extreme difficulty parking between painted lines most days.

There's no way the forum software does that. If it's any consolation, I'm a poor typist, and what's worse is that I can't catch my own errors (other folks' typos jump off the screen at me, but not my own). It doesn't matter which site I'm on, or if I'm typing a document for printing. I always have to come back later and review what I typed and correct my errors.Sometimes I think this forum adds or removes letters to my words in my posts.
