The message the car gives is vague, typical Zoe error message.
First step should be to get a Konnwei OBD adaptor and see what error codes CanZe gives you.
The only thing you can do otherwise is to try another dealer or disconnect or renew the 12v battery.
If you want to fiddle with the 12v battery then open the bonnet and with the car off monitor the battery voltage. If you don’t have a multimeter then you shouldn’t fiddle with the car. The battery voltage should be around 14v with the car on or not sleeping, so wait till the battery drops to a resting voltage then wait another 10 minutes and disconnect the earth lead to the battery.
You could try a new battery, Renault used to recommend changing every 3 years but this is rarely necessary.
Be thankful you’ve got CCS.

 

Renault still recommend changing the 12v every 3 years and I will be replacing mine again in the next 2 months when the car is 6 years old. ( June 2017 )

I would change it first and see what happens.
12v Batteries are about £70 delivered .( See link below)

Plus if the battery is replaced by a Renault dealer I think that charge £180 which does include fitting.

When I checked the original 12v after 3 years it was still ok but changed it to be sure.

Just like a fossil car if the 12v needs replacing then at this is the time of year with cold temperatures you find that's when the 12v is likely to be at fault.

+1 for 12V battery being the most likely culprit. Buy a new one!

 

Have a look at this thread mentions the 12v battery problem.

AC Charging Impossible !

Hi can any direct me for some help? Today my partners Zoe failed its normal overnight charge and on inspection the dashboard displays a "AC Charging Impossible" message. For a while we thought it was the car that was the issue but after taking Zoe to a Pulse point at local garage realised...

Thanks everyone. I had read that thread which is why I was so hopeful that the starter battery was the issue but when the breakdown mechanic said it was working fine, I thought it must be something else. But it sounds like it could still be the starter battery? Should I try charging the starter battery first - could this temporarily fix it and then I know it definitely needs changing?

 

The breakdown guy would have measured voltage. Just because it says 12.8V doesn't mean it is fine. If the battery is fooked voltage can drop as soon as a load is applied.

 

If the 12v battery is nearly or over 3 years old I would replace it.

As far as I know the 12v battery is not included under the warranty with Renault so if you take it to the dealer and he decides to change the battery first before he checks the car over further they will charge you £180.

Any local garage can fit a battery just make sure it's not a stop start battery.
Costco sell 12v batteries if your a member.

 

here is a great tester to use , puts battery under stress - 'toasters' we used to call them when i worked in motor factors yonks ago , you are not likely to have one of these and even the breakdown guys most probably aint got/use one - but some independent garages and battery specialists should have them. That will test it under load alright!

- mind you the zoe does not have a conventional starter motor to turn over the engine ... if it did and you were hearing the engine struggling to turn over then that would re-enforce that its 12v battery replacement time.

12.7v - 13.2v you want to be looking at for fully charged good 12v battery - do this when everything is shut down on the ZOE otherwise the DC-DC (380vDC-12vDC) converter could be pumping nearly 14v into the 12v batteries and that will give you a false reading of your 12v battery .

good luck

 

In case helpful, my update is I booked Halfords to install a new battery but they called the night before the appointment to cancel because they don’t install batteries on EVs (or hybrids). I have an appointment with Renault for 3 weeks time. I tried tonight using a charger for starter batteries which said the battery was full when I connected it but I decided to try plugging my regular AC charger for the car in while the starter batter was still connected to the charger and the main battery started charging. Clearly an issue with the starter battery as others here have said.

 

so you managed to charge the car with the type 2 charger whilst the battery charger was on the 12v battery yep? a bit unorthodox but if it works thats great.
that was good going, sounds like it worked . well done!

 

Yes - exactly!

 

good tip for the future for anyone who cannot start a charge due to low 12v battery - well done!

 

I have a 3yr old Zoe R135 ZE50 which has started showing an “AC charging impossible” error.

Recommend finding your local Hevra garage!

I had BCI issue. I tried all the suggestions above with no luck.
My dealership charged £1300 to replace the charge harness.
8 weeks later the BCI issue came up again. The issue is now the INVERTER. Dealer quoted £4,600 to replace it. This car is a 2015 reg. not worth that much. Plus it’s a leased battery.

I’ve now parked the car until I get a less expensive solution.
How was Renault allowed to sell the lease battery contract? It will cost £1700 to buy back the battery lease which is totally useless in the car.
