6.6kw Charge Stops Prematurely with EV System Warning Light

Jeremy Patrick · Apr 25, 2015

I have a 2 month old Tekna 6.6 with 3000 miles. Last night, at Manchester GMEX / Central NCP, charging stopped prematurely after 90 minutes. When I came back to the car and 'started' it, the EV System Warning Light and Yellow Exclamation mark was on. The warning lights cleared after restarting the car (though it took a few attempts to get it back to 'Ready to Drive'), and fortunately I'd already gained enough charge to just make it home (though I saw my first low battery warning).

I've read the following DTC error codes using Leaf Spy: B2820 (Quick Charger), B29C1 (EVSE), P3172, P3170, P316C (PD Module System). These correspond to a US Technical Service Bulletin: My Nissan Leaf Forum • View topic - EV System Warning Light

I have a 200 mile round trip to make this afternoon (with an overnight stop to charge at a ZCW hotel). Happily, my Leaf appears to have charged to 100% overnight at home so I'm hoping the problem in Manchester was a charger fault. However, it's left me a little nervous as the Leaf is my only car and I regularly venture beyond its range. As a precaution, I'm going to take a wrench to disconnect the battery terminal, as it may need a hard reset if this happens again.

I've tried to speak to someone knowledgable at my dealer without success, so I was just wondering if anyone else has come up against this issue?

I can recall it being mentioned but perhaps @NissanGB or one of our more experienced LEAF owners will be able to chip in with some advice.

This happened to me the other week on a pod point at a nissan dealer. My cars been absolutely fine since so I wouldn't worry about it.

Thanks @Edd Beesley for the reassurance, which is especially welcome as my dealer hasn't got back to me as promised.

This happened a couple of times on our Gen1 (and others) if charging stops without going through the proper protocol. If it clears on rebooting all is fine.

This happened a few times on the newer ecotricity ABT DC/DC machines last year (shortly before the machines stopped working at all). After repair and new software (on the Ecotricity charger) it hasn't happened again. I just switched off and switched on again and all was OK in the leaf.

Thanks. My weekend trip went without incident, confirming the reassurance from others here. I never cease to be delighted by the level of interest whilst rapid charging at motorway service areas. There was a high level of interest at the hotel where I stayed too, and I made clear they had my business because of their ZCW charger.

Always good to give some positive reinforcement and encouragement.

Hi Jeremy,
Just to confirm the Bulletin will not apply here in the UK. We can't tell you why without investigating further. If you do have further problems, please do book an appointment with your local dealer.
Any further questions, please do let us know.
