I've had my 2013 for over 4 years, but since we've just switched to TOU, it's the first time I've programmed the charge time. It seems to be working, but there is something I'm not sure is right. I RTFM and searched some threads, but I don't see this particular issue.

It holds off charging and seems to start and end when it's supposed to, but in the morning, despite having a full charge, the green light on the dash is completely off, there is a warning on the dash that says something about charging being interrupted, and the EVSE's red LED is on. The first time (yesterday), I thought I had blown a breaker, and reset everything, and it started charging again. However, this morning everything was the same as yesterday, so I left it all alone and just drove off. Center console said full charge and all miles had been reset like normal.

Is it normal to have the green dash light off and the red EVSE light and the interruption warning at the end of a full programmable charge cycle? TFM suggests the dash light should be flashing green for a full charge, even when it's at the end of a programmed cycle.

Appreciate all thoughts, including something stupid I'm missing and nothing's wrong after all. Thanks!

Not normal behavior. I use ToU + Departure time charging, and my car completes charging without any warnings. It is very likely that something (maybe another appliance on the same circuit/phase) is causing a brief blip - causing the EVSE to complain, and your car to report an interruption.

Stromfahrer,
Coincidentally, this is also my first month switching to SCE's TOU rate. I'm very curious how my electric bill will work out, as I've increased charging duration at home for multiple reasons.

With my 2014 ELR, I haven't had any charge interruption messages at home. I'm also using delayed charging w/ timer based on TOU rate and departure time.

Yes, SCE finally adopted a TOU program that wasn't obscene. Until now, the peak rate for TOU was so much higher than the peak rate on the standard plan, that it didn't make sense unless your home was uninhabited all day. I too am interested in the numbers.

This will happen to me if I charge at work utilizing a janky extension cord. I don't have the equipment to test but I'm certain the EVSE is reading high resistance to power or not enough amp flow which will put it into an error mode.

If this is the stock EVSE and you are needing to use an extension cord be sure it's a heavy duty one. Otherwise you may need to change out the plug you are using or make sure it's on a 20 amp breaker not a 15.

Thanks, all, for the replies. This morning all was normal, so I think there was an added load on the circuit somewhere the previous two nights.
