OK I have read through some of the threads here and have not found a discussion on this exact issue I am having. So I am posting this thread in the hope that someone here has seen something similar.
Background:
2015 Leaf SV
Duosida EVSE L2 Charger, 240V 16A
Charging via 220VAC (60 Hz) single-phase outlet at home (properly sized breakers, proper wiring, proper NEMA plugs)
Charging via 208VAC (60 Hz) two-phase at work (properly sized breakers, proper wiring, proper NEMA plugs)
When charging at work, I have never to my recollection experienced any charging faults. I can L2 charge when I arrive and be sure that I will have a full charge when I leave at the end of the day.
However, charging at home, with the SAME car and SAME EVSE (I carry it with me) I have so many charging faults that it is becoming an issue. When plugging in, the first three lights on the EVSE will light up as they normally should, and the Leaf will beep and flash the dash top charging lights as normal. However, if I return in the morning, more often than not, the EVSE fault light (amber) will be lit up, and the car will not have a full charge. Based on how little charge it has received (less than 10 miles or so) the fault must be happening shortly after plugging in. The problem seems to be getting worse.
I have used a DMM and checked the voltages across the two legs, and with respect to ground, while charging and while not charging. I do not see any issues. Both legs carry the same amount of voltage with respect to ground. The outlet the charger is plugged into has a dedicated breaker, wiring, and plug, with a short run (less than 20 feet) to the breaker box.
Since the problem is only at home, and not at work, the problem is IMO either from wiring issues at the house, or from power fluctuations on the grid. My house power company and work power company are two different companies by the way, so the latter is possible. In fact I had the power company at my house today to look for problems on their side of the meter. No word yet on whether they found anything.
Since I have no problems charging at work, and the car has the latest dealer-installed software on-board, I do not suspect it is an issue with the car or the EVSE.
So, that's the story. The question is, has anyone seen this sort of behavior before? If so, were you able to resolve it, and if so, how did you? It is to the point now where I am considering the purchase of a 240V power conditioning unit (with enough amperage of course) to put between the EVSE and the house. They are on the order of $300 from what I have seen.
Thanks
