So while fast charging my 2013 Renault Zoe I got a pretty serious message

Strangely I can still drive the car as normal (apart from cruise control which is disabled), but I can't charge the car at all, I've left the car overnight to see if it would clear but it's still showing the message and I can not charge the car.

because of the coronavirus, my Renault garage is only looking at key worker's cars. so I was wondering if anyone has seen this before could this be a simple? the Battery light also came on at the same time

When we got that it was the car detecting low earth resistance somewhere. Went away on its own overnight, and it was raining pretty hard when it came on when on motorway. Garage couldn't find cause and charged us for the privledge of looking for one.
Hasn't returned.
Really you need the error code to be able to know more.

It's got the 12v battery warning not traction battery. When was the 12v changed last?

Zoe likes to throw up random errors that will come and go all the time, and they are often way more dramatic, and typically unrelated to whatever the minor issue actually is. (I've had this very message simply because I moved the gear shifter slightly too fast after starting it up before, seriously!)

As has been mentioned above me, I'd be looking at the 12v battery. Especially if its the original then a replacement would be a good call. If its been replaced fairly recently then give it a charge if it looks low.

Even just disconnecting the 12v for a little while will probably clear the warning. But if it is that battery at fault you're just going to have it come back and cause more problems at inconvenient times until you find yourself stranded somewhere.

Search the forum for the fault displayed. You'll quickly find lots of advice: Search results for query: STOP, Electric failure DANGER

I'd also start with the 12V battery: Battery tester for 12V battery

Orange warnings are usually nothing, and as said often related to the 12v. Red warning are generally not so simple, the can be triggered by the 12v, so give it a top up charge, but if they don't go away then you might have a more serious issue.

12v low, potentially because of DC-DC converter fail. Recharge/replace the 12v battery, you'll get back cruise control and charging. If the message re-appears, you have a failed DC-DC converter failure. Is the car still under warranty?

Hi, whereabouts in the country are you? There are some very good independent EV garages under the HEVRA network.
Cheers.

As your car was charging when the message came up it is unlikely to be the 12v battery that has failed. I don't think it was low charger earth resistance as that gives a "check charging post" message, and will only occur at the start of a charge.
As already stated the voltage on the 12v battery may be low if the DC-DC converter has packed up. This can be checked easily with a voltmeter, the voltage should be around 14v when the car is energised, and just opening the door starts the 12v charging.
Do you have a home charger or granny lead ? There have been instances where 3 phase charging ( ie rapid) has failed but home charging (single phase ) has worked. It is a long shot but try to loan a granny charger if you don't have a home charger.

Thank you all for your replies, I've tried my granny charger but nothing even tried letting the car fully shut down and plugging it in to see if I could trick it into charging but nothing, checked again this morning hoping it might magically clear but still has the fault, I'm in Essex by Southend-on-Sea but think I might try and find a garage to test the battery to see if that's a problem before taking to a specialist, it's unfortunately not under warranty so I'm really hoping it just the 12v battery 😅

You can get cigarette lighter socket USB chargers that have a volt meter built in to them for a few pounds. They make it easy to check the 12 V battery voltage. Just be wary of their accuracy some of them aren't very good.

Oh hi, i'm only up near Chelmsford if you want to try our charge point, I also have a diagnostic machine for the Zoe as I fixed a few things on mine so I can check the error codes. Obviously once travel restrictions have eased.

Cheers.

If your talking about an icarsoft i907 that won't clear HV faults I don't think. Its ok for stuff on the 12v bus.

Its an icarsoft but the newer one, cant remember the model off the top of my head. It tells you what the actual error is which is the most useful bit!

Cheers.

Thank you, but might have to go back to Renault for repair, the 12v battery is giving a reading of 13.4v (disconnected from the car) and 14.4v when the cars running, seems slightly high but I dont see why it would stop me from charging the car.

 

[BogieMan]

The 14.4v reading is quite normal, so the DC to DC looks good.
Let us know how you get on and good luck.

No worries, hopefully you get it sorted!

Hi all, Just a quick update, I picked up a Konnwei 902 dongles to get an idea of what the issue could be and noticed I was getting an error which makes me think my inverter has blown but I'm not 100% sure, I get the message E-Message.isotp.startswith7F and it gives me the part number 291A51613R which when typed in google comes up with the inverter.... no warranty on her so looks like it will be an expensive repair, has anyone had this code or had to have the inverter replaced after warranty? could do with an idea of price because Renault want £107 just to look at the car .

Oh shucks! I haven't checked error messages with CanZE, so can't confirm the part number.

I had mine replaced, though under warranty so free of charge, and when I asked the technician what would have costed me should my car be out of warranty, the answer was "about 5000 eur, incl. shipping and labour" (it wasn't a second hand item, but from factory); that's because they replaced the entire motor assembly and not just the inverter.
