My workshop is about 5 miles from home. I never had charging issues with either the 2011 or 2015 at the workshop or at home. I was concerned that the 2019 would not charge reliably from the 208-volt source, but it seems to charge without disruption using the Clipper Creek EVSE as long as I don't lock/unlock/open/close the doors or hatch.
Interesting, as those are all 12 volt powered. Have you checked your accessory battery voltage lately?

I have not personally checked the 12-volt battery because the car was manufactured only 2 months ago and the DC-DC converter should be float charging it at a suitable voltage while the car is charging. Also, I would expect similar failures at home if the issues were related to a weak 12-volt battery.

True enough, and I forgot that you had a new Leaf. It just seemed odd that using a 12 volt accessory would disrupt charging at marginal charging voltage. I guess it's the DC-DC converter causing a slight additional voltage drop that sets it off...

I doubt that it is related to charging voltage. I suspect a glitch in charging timer software or possibly the WiFi connection that the SL+ allows is somehow causing charging to stop. I paired the navigation system to the router in my workshop so it could search for map updates and now it automatically connects whenever I park there.

Gerry --

Please try using the timer override button at your shop. That's what works for me, despite the fact that I have "charge timer only at home" turned on.

Paul,

I plan to turn off wifi in the navigation system and turn off all charge timers before I try charging again at my shop. If it charges without incident and allows me to open/close/lock/unlock doors without interrupting the charge, I will turn the charge timers back on and test charging; I will then turn wifi back on and test. Hopefully, this will show what is causing charging to stop.

Time for some more testing:

The car is charging at my workshop. I turned off WiFi before attempting to charge to make sure there was no impact from that connection. Time is within allowable charge timer window for charging at home so charge timers should have no impact even if it not set for HOME only. Doors were closed and locked. I initiated charge by plugging in EVSE cable and charge started normally. I went out to do some testing after about 15 minutes. Unlocking doors had no impact on charging; opening right front door had no impact; charging stopped when I closed the door.

I then turned all charge timers OFF in the settings menus on the dashboard in front of the steering wheel. I turned off car, exited driver door, closed door, and locked car before initiating another charge session. I let the car charge for a few minutes before testing again. I then unlocked car, opened front passenger door, closed door, and locked car without charge being interrupted. I tried several times, opening all doors and hatch before closing and locking. I waited a few minutes and tried again. I have been unable to cause charging to stop since disabling the charge timers.

Therefore, it appears there are problems with the charge timer or navigation system software (or problems with communication between modules).

Thanks for posting this.

It seems like your experience is similar to mine; I sidestep the problem by pushing the "Immediate Charge" button rather than by shutting the timers off.

Is there some way to make Nissan aware of this problem, or are we merely trees falling in the forest with no one to hear?

Paul,

Have you verified that the timer(s) work as expected at home? Have you tried turning off the "home only" setting to see what happens?

I have a couple more things I want to test before I raise the issue, but I fully intend to call the Nissan EV Customer Service line.

Yes the timers work as expected at home, regardless of the "home only" setting.

I only experience bad behavior away when away from home.

Please let me know Nissan's reaction. They told me to take it to a dealer for diagnosis, which I feel would be a waste of time, no?
