Thank you SOOO much. Phew!

Of course, you could just be humoring me.


One of my friends said he saw that option too.

During my reservation process, I selected the SV. Before I went to the next step, a message came up and mentioned the Quick-Charge connector was only on the SL and would I want to upgrade to SL? I switched to SL and noticed that the Quick-Charge wasn't mentioned in the additional options list for the SL.
Thought it was kinda weird but I agree with the earlier post that Nissan seems to be making up some of this stuff as it goes along.

They don't make this connector, and may not have had supplier agreements about pricing signed-off yet. So, the current pricing that Nissan was anticipating for this connector is not cheap by mass-market auto standards and it's one more place where they're trying to control costs. I'm sure the wiring is in place for the backup camera and solar panel on the SV as well. They were just clumsy in how they handled this feature on Apr 20. I hope and expect that by May 15-June 30 we'll learn that us early adopter types can switch colors, options and lease vs buy freely right up until sign-off.

I reserved the base model and got no such popup.

The "extras" listed for the SL didn't sound all that important to me, hence the decision to go with the base model. But I've had this nagging concern there will be other "little touches" on the final SL that weren't listed, like maybe nicer fabrics or other trim (I'm not interested in upholstery fabric made from woven seaweed or post consumer wood chips). I've been meaning to get back to Nissan and get some confirmation whether I can revise my decision once the final feature content of each version is specified.

At this point it almost seems like they are floating trial balloons on some of this stuff.

I also "reserved" the SL, and got no L3 message.

The L3 connector itself, in large-quantity purchases, should not be very expensive. The L3 communication, control, high-cutrent wiring, and the safety interlocks might already be in place, but could be more expensive than the single L3 connector.

We might be charged $400 for one connector at the service department, but in 25,000 quantity they might only cost $4 or so to make.

I guess I see now why they would have two connections, one for AC and one for DC charging: If the DC port is wired straight to the batteries and the AC (1772) port goes to the AC onboard charger wouldn't it take a monster relay (or two) to switch between them if you wanted to do it all through a single connection?

Yes and no. The J1772 standard calls for up to 9 separate pins in the connector, including two dedicated to AC and two dedicated to DC. (The others are for grounds and control/data communication.) But the Yazaki connector being used only has five of those pins, and does not include the DC pins.

Is the "9-pins" in some early version of (or proposal for) the J1772 standard?
Or, perhaps for the older "square" connector?

I believe the latest version has only 5 pins, one ground, two for AC power, and two for "control".

One control pin appears to tell the car that the EVSE is alive, and what maximum current is available. On the same wire, it appears that the car can signal at least "charging" (or "not"), by loading the signal line with a resistor (or not).

It appears that the second "control" line does not go to the EVSE at all, but just just provides "connector inserted" and "connector latched" indications from the plug to the car (done with one switch and simple resistive loads).

Oops, my bad. I was looking at a very old version.

So it seems unclear where they are with the standards, but fundamentally you could apply a variety of voltages in either AC or DC through just two pins on a single connector as long as the handshaking tells the car what it's going to be getting. That process had better robust though so the car is damn sure what it's going to be getting. If there was a screwup in that process and the car closes the wrong relays it won't be pretty, for example applying 600V DC to the input of the AC charger, or applying 240V AC directly to the battery.
