Here is a very good video that explains all the different charging levels and connectors. And at 40 seconds in is a part just for @insightman who keeps us straight on modes and in this case what’s a charger and what’s an EVSE. (Hint: You’ve never plugged a charger into your Clarity. Ever.) It was nice to find an informative EV video that isn’t riddled with errors. https://www.cnet.com/roadshow/videos/making-sense-of-electric-car-charging/#ftag=CAD-09-10aai5b
Well done. I'm not sure he got the 240V J1772 pin-outs correct, but I've no quibble with the overall information and how well it was presented. Thanks for posting.
It is a good video. Being picky, I don't think any level 2 goes to 90 kW. The Teslas have dual chargers for an option, so they could take 80A or 19.2 kW if equipped with that option. I've never heard of any level 2 charging beyond that amount. And I don't think any J1772 connectors will go beyond about 40A. 90 kW would be 375 A at 240V.
Yeah, I thought about that too. It seemed like he was defining Level 1 , 2, and 3 EVSEs by the voltage doubling and not the power. Does anybody know the correct or technical definition of Level 1 vs 2 or 3 EVSE?
Ok. I found a link to a somewhat dated descriptions of charging standards. https://share.ansi.org/shared%20documents/Meetings%20and%20Events/EDV%20Workshop/Presentations/Pokrzywa-ANSI-EDV-0411.pdf And I was wrong in my statement above. Level 2 can be AC or DC and DC does go to 90 kW at 450V and 200A. I never knew Level 2 was anything but AC. AC does only go to 19.2 kW. The chart shows level 1, 2, and 3 for AC and DC (even though it is somewhat dated at 2011).
Thanks, Robert. Wow, SAE says Level 1 can be 120 V, up to 19 kW, 16 A. And Level 2 can be 240 V, up to 19.2 kW, 80 A. And it even defines DC for each Level as you pointed out. That is very helpful info for those installing Level 2 EVSEs who are trying to future proof the wiring.
That is VERY useful info. Thanks for digging it up. As I contemplate what to do for Level 2 in my garage, it’s good to have the standards.
Whoops. Typo in post #6. The 120 V was supposed to be 1.9 kW not 19 kW. Thanks again for sharing this great info, @Robert_Alabama.
