Good question. I had verified that the charging timer is off.
Also, another thing a 12v battery that is not fully and completely charged can have issues for charging the traction battery. testing it with equipment doesn't prove anything, even the voltage will show as happy. the only way I got rid of issues was to hit it over night for a few nights with a Battery tender.
I will try that next.
Do you have a USB dongle on the OBD port and leaf spy pro so you can run to see if any DTC errors are there?
Good idea. I did that a few times today and there are no errors related to the charging. There are some codes from the removal of the Bose stereo, and the still-not-working Nissan Connect unit, but I knew about those.
Are there any other circuits in your house that are dodgy? if one of them has an issue they could trip the EV ground and cause it to stop. maybe switch off all unused circuits in the house and only have the CAR one on and see if it works.. then you can work your way through the issue. I don't know if it would be possible to do that.
It is a newer house, about 10 years old that was built for us, and everything was done to code by a qualified electrician. No problems with the house wiring that I know of.
Does the error happen, every night or just once in a while? if every night it would be easier to find the gremlin.
It has been happening every night at home, and never happens at work, ever. But it gets stranger... On two different nights, after the EVSE showed a charging fault, I reset it by unplugging and plugging in the EVSE on the outlet side. Both nights, the car charged fully after that. I am going to try the same thing again tonight.
The electric company has installed data recorders on my meter and in the house to look for electrical anomalies. The jury is still out, but the technician mentioned they did see some power fluctuations. More testing needed.
