10% EV range loss in 3 years? How to check battery state of health (SoH) in Renault Zoe 2020 model.

SoH=94,74 after 129,650km driven om my May 2020 ZE50 R135 (it had 8200km on the odometer when I got it in Nov-2021).
You NEED to get the "Battery managment System ACTIS 64453" update.
And "Energy screen + improved Pre heat system ACTIS 64756 and ACTIS 64273". This is needed for all spring 2020 cars.
They will complain and trying to avoid doing it. but stand your ground and demand it. Both helps a lot.
The usable "range" is the average related to the SoH and the avarage consumption from the latest 10 trips (so that part is temperature dependent). And without doing the ACTIS 64453 it is basically useless as in that software you have it is very temperature dependent.

Doing service on Zoe is an expensive 20 min joke. They only replace the cabin filter. All other is just useless checkpoints that make zero sense. The first that really matter is 12V battery replacement after 3-5 years and braking fluid after 5 years (can not be done at home due to ODBII operation is needed to properly flush the ABS system).

I havnt got a ev but interested in one for a future buy.

I regularly check the SOH of my sandero car 12v battery so i wonder if the SOH that you are checking is the 12v battery which operates lights etc in the car and not the main motor battery . I would anticipate the voltage drop that you are showing from the 12v battery and anticipate replacing this as part of normal maintenance around 5 years just like a non ev car

The EV 12v battery charge is relenant is that it can show an engine fault I understand when it gets too low when in fact the main hv battery is perfect.

Is there any progress on this situation? In some forums, it is said that the ACTIS software needs to be updated.

Hi Folks.
I am about to Check my Soh soon. (R135, 52kWh, 2020, 29tkm)
When it comes to updating the firmware of LBC, what was the Price for such Update?
I read some Blogs which stated more than 500€ !?!

My concern is yhe obd2 you recomend clearly states not suitable for hybrid or electric so if this is the case are you seeing the auxiliary 12v battery condition?

92% after 4 years - 57.800 km - ze 40

Please make this correction - it's OBD standart and O B D device On-board diagnostics (OBD) not odb :)

Looks like you haven't had the BMS update. My June 2020 Zoe had a SOH of 88% prior to having the update. After update the SOH showed up as 98.8% in June 2021. After 25000 miles and 3 1/2 years it is now 96.6% .

bought from Norway 94500km SoH 98%, now 96000km SoH 94%, with the onset of cold ,Soh decreases? ze 22

The measured SoH may be incorrect. Try calibrating it. Drive the vehicle until it reaches 1% charge. Then, park in front of a max. 11 kW charging station. Set the temperature to activate the air conditioning compressor, and wait for the vehicle to shut down itself. Let the car remain locked for 1 hour. Then, connect the charger and wait for it to reach 100% charge completion. Afterward, you will see the true SoH value.

91% after 4 years and 5 mounth - 87.200 km - ze 40

Thanks a lot – really appreciate what you give us all here.
I’m getting my OBD2 immediately

Hi, there's an official software update at the dealer for unreliable readings in range pn the ZOE50. Renault call theses updates "Actis". The one you should ask for, at a friendly Renault EV dealer, is ACTIS : 64453. This updates both lbc1 and lbc2 controllers. You can google that, you will find answers in German and french forums. Cheers from 🇨🇵

For me, the "state of health" option does not appear in the "all sensors" list

Hi,did you already have an BMS update?

Hi. When measuring the battery status does the Zoe first need to be fully charged?

My car is Zoe r135 2020 , at 78.000km . Soh is % 94.75 . This number is really bad , but my range is still same as factory data.

YA THESE EV CAR VAPE BATTERYS ONLY HAVE 1000 CYCLES AVOID

That's French quality. Should have bought a honda or toyota.

Toyota Aygo no loss of range in 13 years......😮

What the name of the app?

How do you measure Battery SoH and did you ever get your pack replaced because of it at the dealer? Was it tough to convince them to do this?

Hey
I have got the same car, only a couple of months younger and 33000km. I have measured the SOH over a couple of years using the CANZE - app., extracting the same data as the CAR SCANNER. Over time SOH has gone from 98% (spring 21) to 86% (winter 22) to 95% (summer 22) to 88% (winter 22) to 97% (spring 23) and now 92% (summer 23). So I dont find it very reliable. I have for 1½ years calculated the SOH : Energy (kWh) when full (green light at the socket) divided by 52 kWh. The results from these calculations also varies with seasons but are generally higher as the measured SOH's - last calculated 97% vs measured 92%.
