Re: EV system warning light. What may have cause it?

Mon Aug 06, 2012 5:28 pm

Got the car back from the dealer today. They said the car had gone into some sort of 'partial shutdown', where it disabled the charging because of the code, which did occur during the attempted Quick Charge. Everything appeared functional after that and he also attempted the Quick Charge, which worked with no issues.

Unfortunately, after picking up the car, the car was down one capacity bar. The 100% full GID reading before I dropped off the car was 209, so I knew it was close, so their QC and high-heat parking (Thanks, Nissan Dealer) pushed it over the edge, I'm sure.

Other than that, the dealer provided a nice rental car with no charge. Thankful for that.

More specifically, it was interrupted while remaining plugged in. If you interrupt it by unplugging you don't get a light. If you interrupt power while plugged in (say by unplugging the portal EVSE from the wall first and the car second) you'll get the light. The light will stay on until you power off the car. To verify, power cycle the car and the light should go away.

I think my situation was a little different. It stopped charging very quickly while plugged in, then I had the light active. The light remained on through a couple power cycles. And, while the light was on, the car wouldn't accept an L2 charge.

I confirmed with the service tech that in my situation, there was no sequence I could have done to fix the situation - it was only servicable by the dealer.

I see this warning light pretty much every time I charge at work. We filed a ticket with Eaton, the manufacturer of these stations, but there is no resolution to date. I have to admit that it startled me a bit when I saw the warning light for the first time. Eaton supposedly inquired with Nissan, and we were told to power cycle the car to reset the indicator.

I'm going to piggy back off this thread instead of posting a new one. See searching does work =)


First off huge thank you to Dave in OLY for tweet troubleshooting last night. I was kinda freaking out.

Time line:
7pm
Drove home with 3-4 bars of juice left @30*F.
Garaged car, set the CC timer for the first time ever.
Hit the 100% override
Set Schneider EVSE to 8 hour delay
Plugged in vehicle

830pm
Wife comes home and comes upstairs, "do you smell an electric smell in the garage?" I ran down and checked the garage. I didn't really smell anything I could pin point and checked the car. The EV System Warning Light was flashing away. I checked owner's manual. Unplugged car, turned it on and drove around the block. It seemed fine.

Plugged it back in. The blue dashboard light illuminated, the circuit breakers popped (as normal), the car beeped and acted like it was happily charging.

I checked the EV System Warning Light and it's still flashing away.

Unplugged car and tweeted Dave.
Turned on car and took car to dealer with 12 miles left on the GOM and 2 bars of charge. Dealer power was out thanks to the snow storm. So they can't accept the car to do service, plug it in to charge, use any kind of diagnostics and it's probably a 3-4 wait still for power to get back on at the dealer. EV System Warning Light still flashing away happily on the dash. Stupid light...grrr.

So power cycling the car didn't resolve the issue. The EVSE plug looks fine and the pins on it and the charge port look fine.

Hopefully dealer can explain the situation. More importantly that they don't try to assess a fee for any actions (almost wrote charge but that could get confusing). That and get the thing indoors. I don't like it sitting out in 20* weather with almost no charge in the traction battery.

Ideas? Questions? Comments? Am I just freaking out (yes).

1. Pull the negative terminal off the 12v battery for a few minutes - that may work to reset things. Failing that - sometimes these things can take multiple power cycles to "clear".
2. Don't worry about being in the cold with 2 bars remaining - that's plenty.

That COULD just be the smell of the heater, but given that it happened at the same time as a fault, I suspect something has failed.

Certainly the dealership doesn't know since they closed up shop without calling to let me know they closed. Found out by calling the Hyundai and then Chevy dealership down the street that are the same auto group. The VRU on the Chevy says 'closed due to inclement weather'. So assumption is that all 3 are closed. Would have been nice to get a phone call telling me that. <insert expletives>

Re: EV system warning light. What may have cause it?

I have performed diagnosis on this issue and concluded that it's due to a Blink restart during charging. The blink EVSE will reboot for some unknown reason while leaving the contactor closed, and then when the pilot signal from the EVSE goes away, the Leaf's OBC will report a EVSE fault to the VCM. This causes this warning light, but it is temporary and will automatically reset upon a drive cycle once the Blink is disconnected.

You can verify that this is indeed the case by going into the blink's "Settings" menu and selecting "Device Info". Observe the "System Uptime" figure which should be the elapsed time since the errant reboot occurred.

This seems to occur less often in the newer Blink firmware. All Blink EVSE's should have firmware 2.1 by now, if they don't, it's probably because your internet connectivity is bad (Blink WiFi problem) or you have a defective SD card in the Blink. Call Ecotality and tell them you are having this issue and would like your firmware upgraded.

In the meantime, use one of our upgraded units instead of the Blink if you have one. They will not cause this problem, and you'll have your intended charge each night instead of an unpleasant surprise in the morning!

Phil,
If the blink comments were directed to me, I've got a Schneider device. And car's still in shop but at least they have power now to do the diagnostics. Why they haven't completed that after being open 2 hours is another question....sigh

<edit>
Wife called and said the light's not blinking now and they don't know what caused it.

Using CW (since it's working now) I could see that it took a charge and release a charge. It was at 4 bars/40 miles and now it's at 3 bars 26 miles. Wife said they were taking it for a test drive so that hopefully means they did that and had the climate control blowing and did it on the interstate. The only other reason to loose that much that fast is a problem.
