L2 not charging, L1 ok

Sat Dec 17, 2011 9:42 pm

At almost 3 months and 4K+ miles.

L2 failed at multiple locations around town and the home garage. Home EVSE shows ground fault. L1 is working ok, but not pliable for charge-and-go situations.

Leaf wiki searches turned up nada.

Hope to take it to the dealer (with appointment) asap. Need to thumb through the manuals. i have read exactly 0 pages so far. Plan to call Nissan CS as well.

Suggestions gratefully accepted.

Odd that L1 works ok. Might have something to do with one leg being
at ground potential where with level two both legs are hot?

At any rate, I think you have it right. If it fails on multiple L2 EVSEs,
there is probably a problem with the car. :(

We had one other member report a problem like this. It turned out the car was failing the diode check used to be sure that the handle is actually connected to the car. The L1 that comes with the car and the AV EVSEs used at the dealer don't do the check and worked with his car, but the Blink he had at home DID do the check and failed. He had a real difficult time convincing the dealer that there was actually a problem. If I recall he ended up having engineers from Nissan and Blink involved before Nissan finally fixed it.

If the EVSE you have at home and the public ones you tried follow the standard and make the check, this would be the result.

Appreciate the response, Dave. Yours is the most plausible explanation i've heard so far. Thanks..

My home EVSE is from Schneider. It worked flawlessly for 2 months before starting to fail intermittently. Then charging stopped altogether. Schneider was gracious enough to send me a replacement unit, which had the same results. Then it failed on multiple EVSEs i tested around town (Chargepoint, from Coulomb Technologies).

Have not tried charging on AV since the problem started. Called the dealer and found out that they have AV. Am taking the car in tomorrow morning.

Have not charged on AV yet.
The dealers use AeroVironment (AV). They are Nissan branded and look like this:

Took the car in to the dealer's service department. We managed to duplicate the problem just exactly as Davewill had mentioned above. Charging works on L1 & AV, but fails on Chargepoint & Schneider.

Awaiting an answer from the dealer after they get in touch with Nissan.

Everything else about my car has been just fine. The dealer was very patient in diagnosing this.

A big shout out to South Point Nissan in Austin, Texas. My guesstimate is that they have sold 100+ Leafs in the past year. The Leaf master technician told me that just one or two cars have been back at the dealer with minor troubles.

A bit off topic... I would love to know the LEAF-sold count per certified LEAF dealer across the country.

Sales rates down here in South Florida seem to be very low (which is sad, but not very surprising). Maybe a half dozen, or so, on the high side with many dealers having sold only one or two.


Now, back on-topic, as a Schneider EVLink owner it's nice to know that's not the problem. Here's hoping whatever the issue is with your car's charger is resolved quickly.

Ding! I know what the problem is!

The diode in your charger unit is fried. The L1 & AV units don't test for the +/- 12 volt signal, while the ChargePoint, Schneider, and Blink do.

A guy here in Portland had to get his whole charger unit replaced in his Leaf because of a problem with very similar symptoms.
