- Check your electric car battery pack state of health with the OBD LINK MX+ (Amazon): amzn.to/3oWbp9u . Has the 2020 Renault Zoe lost already 10% of its original range in only 3 years time and only 23.000 km?
My wife's Renault Zoe electric car from 2020 has driven only 23.000 km, but has lost about 10% range during the spring/summer season. Normally she would get over 300 km range on a full battery charge driving the same highway route every day. But now she has not seen any 100% range over 260km.
In this video I will show you how to check the battery state of health in your electric car. This is the OBD reader used in my video:
You can collect and monitor these statistics over time. And you can use them to convince the dealer that there maybe something wrong with your electric car's battery and that they should investigate this for free. Maybe you are entitled to a free replacement battery pack under the warranty of your electric car.
How do you measure battery state of health and do you also use a OBD reader? Did you every have a faulty electric car battery replaced which was losing range too fast? Are there any tips you can share how we can measure this more accurate?

Check your electric car battery pack state of health with the OBD LINK MX+ (Amazon): amzn.to/3oWbp9u . Has the 2020 Renault Zoe lost already 10% of its original range in only 3 years time and only 23.000 km? 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?
I had the BMS / LBC updated because the predicted range was behaving strangely: after resetting the trip meter it showed very low range and then counted up while standing still...
It was a firmware software issue
Thanks for your suggestion and for sharing. I think my wife should do the same with her car, I have the feeling the range is more than it shows. Let's hope they can do it for free with the next planned service interval!
Thanks a lot - really appreciate what you give us all here.
I’m getting my OBD2 immediately
You are very welcome, glad I could share this with other people. Such a cool tool to have in your pocket, can make starting a discussion with a dealer so much easier this way. But I hope you will not need it ;)
it's O B D not ODB On-board diagnostics (OBD)!
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).
Many Thanks this is by far the best number I have seen on a Renault Zoe after that many kilometers. I'm putting your comment on the top and will copy paste it for my wife to demand the update and send it in writing to Renault Netherlands. Many thanks for sharing this is very nice and super helpful!
My Zoe has recently passed 160,000 km and the SoH is now at 93.38%.
The Zoe ZE50 battery pack warranty is less than 8 years and less than 160,000 km AND below 70% SoH for a warranty replacement (75% for ZE40).
My driving habit recently may be the reason for the faster degradation. For about the last 100 traveling days, I have returned home with less than 10% SoC...
For the first 100,000 km, I only got back home once with less than 25% SoC.
Regarding needed services. I have just figured out that the brake fluid exchange is just like any normal car. Also, the coolant exchange, using the original Renault coolant is a must, but it MUST be a vacuum exchange procedure to avoid air traps. Air pockets might destroy the electronics due to lack of cooling, so be aware...
I had to replace the brake pads on one rear wheel due to crappy adhesive, so the brake material dislodged from the steel plate. Figuring out the EPB (Electronic Parking Brake) took some time, but basically, it is just 12V DC directly to the motor and reverse it for changing direction. But I will replace both rear discs and a new set of brake pads on both sides as that side with the faulty brake pads was severely corroded. Maybe I will do a YT-video about it (at least the second side).
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.
Hi that's indeed a very good tip I haven't thought of yet. Basically run it to complete zero and follow your steps. I will give this a try soon with my wife's car and see what happens. Thanks!
Generally manufacturers recommend below 10% then to 100% but I guess the lower the better. And to do this every 3 to 6 months
I know Tesla do, and MG
Tesla bjorn ( bjorn nyland) has just posted 3 videos about this and a cupra born, this didn't work in his case but I suspect it could be a faulty battery pack in the cupra.
@danuk2005 Thanks for the comments and reference. I will keep on doing this in the Renault Zoe the results are still there. Not sure why in my Opel Ampera-e I did not notice anything again first time maybe I will try it again 👍😀⚡
Good point; but this method will not take in to account the losses from charger to the battery which is perhaps 5-10% (if I haven't missed your point)...
I think degradation measurement is very difficult and only an approximation is possible and I will propose another method:
If you charge your car 20 to 80% say five times which makes 300% over the period (assuming you've zeroed the consumption at the beginning) now read your car's total (drive and accessories ie a/c etc. - Megane Etech seperates these two so you need to add) consumption meter then divide by 3 for our example case you would get a better battery capacity measure; I think. What is your thoughts ?

@gokcemuratozaydn799 Hey thanks for your suggestions. This is good and worth trying too as another means of checking and monitoring this. These data combined with one's own observations about how the range developed can help convince a dealer to check your car under warranty. I also noticed an improvement in range after I fully charged the Zoe battery then drain it to zero and then recharge it to full again. The range stayed and was probably there due to some recalibration of the battery. Thanks for sharing your suggestions here with other viewers!

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% .
Thanks for letting me know. I think I will indeed double check this for my wife at its her car. I hope the BMS update is for free even when out of the warranty period?
96,68% ? That is suspicious if you exactly have the same
Hi. When measuring the battery status does the Zoe first need to be fully charged?
I believe this is not required. Mine in the video was not charged to 100%
Is there any progress on this situation? In some forums, it is said that the ACTIS software needs to be updated.
Not yet from my side. It's my wife's car but she agrees next time we will force the dealer to update it based on all the useful feedback we have received here. The update is essential and should be provided to anyone free of charge by Renault. Battery management software updates are in my opinion an integral part of the car.
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.
Thanks for your confirmation on this. That's same car as my wife's but with more kilometers on the clock. It seems like this is just a reference number, but more parameters are required to interpret the battery condition and degradation. How about in the winter when it's cold. You have still the feeling the range is equally as good there as it was when you got it?
@@maximaalski In my opinion, there is no change in the range for now. only the battery health values seem low.
Please make this correction - it's OBD standart and O B D device On-board diagnostics (OBD) not odb :)
I know :( I found it very tough for some reason to pronounce it the correct way. Whatever I did it just flew out in the wrong letter order. But I've been practicing and in the future I will try not to mix it up any more.
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%.
Hey Jan many thanks for sharing this and your experience with the measurements and actually interpretation of this SoH number. Quite amazing to see all the fluctuations over the years and especially the seasons. I will actually try out your strategy here and see what numbers that produces. Did you have to drive the Zoe completely to almost down to 0% to get the best readings or this is not required? Also curious if you ever had a discussion about your findings with the dealer... Did they say anything about your investigations, or did they do an update of the BMS? Many thanks for the feedback and have a nice evening.
@@maximaalski H
Hey Maximaalski. I have not talked to the dealer about the issue - I dont think it would be to much use. I did not drive down to zero. When calculating the SOH I used data from Canze showing availible energy (kWh) then charging to finish divided by nominal capacity (52kWh). I found a relation between battery temperature (°C) after charging to full and SOH: SOH= 0,4696 x temp. + 87,644 with R^2 = 0,63
Have a nice day🙂
Cool! I will try it out, thanks so much for sharing this is great info!
Do you know if your Zoë is on the latest BMS firmware, (I couldn’t get that bit to work on canZE) but maybe worth investigating. My dad has a 22kwh Zoë 6 year old with 98% SoH.
Hi. Do I have to buy the paid version to see the battery life? Because after connecting and selecting Zoe, it shows me an empty field in place of soh. . Thanks
Hello no you don't have to. I use the free one only. Maybe depending on your model and year there are several connection profiles in the app for the Zoe. I suggest playing around with the connection profiles for Renault available and see if one differs from the other. I hope it will work for you!
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.

Hello thanks for your message. I can highly recommend an EV. We have an 2019 Opel ampera-e for longer distance (65 kWh) and a Renault Zoe (52 kWh). The Zoe statistics shown in the video are from the main battery pack and state of health. The 12v starter battery needs to be checked separately, but I would check it rather with clamps on the battery itself with a conventional reader when the car is turned off and left idle for 15m or so. I think that statistic would be more reliable than via the OBD tool. The car recharges the 12v periodically when plugged in or left idle. But My 12v battery is now almost 5 years old and I will be replacing it as a precaution probably by the summer. I always drive around with a booster battery pack in my trunk just in care especially for loner trips not to get stranded somewhere. Just common good practices as with a normal car. Have you already decided what type of EV you're looking to buy? I hope you will like it and let me know if you have any further questions
Take care and happy new year!
What you check on the 12V battery is the CCA and the steady-state voltage. Those two figures give a rather good indicator of the state of the 12V battery. I have so far not read anything about problems with the ZE50 12V battery (if not the result of total neglect). The onboard 400V/12V charger has a 200A charging capacity and has very high efficiency combined with smart charging (also temperature-dependent charging voltage). On the ZE40 it is a rather different story. 400V/12V charger with only 100A capacity and a constant voltage charging scheme so overcharging in summer and undercharging in winter conditions. The ZE40 only charges the 12V battery during driving and active charging. Never when the charger is "only" connected, so having the ZE40 just plugged in for a few weeks and not used may destroy the 12V battery...
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?
Hi I actually have never used my MX+ from obdlink (yet) to check the 12v battery status condition. Only used it for checking battery State of health and main traction battery stats. This works perfect on both my Opel Ampera-e (Chevy Bolt EV) and my wife's Renault Zoe (both new electric cars from 2020). I do believe you can pull 12v battery stats from it, actually I can do this and take a look for you and send you some Screenshots. I'm quite curious myself as now my 12v battery is 4y old. Perhaps need to replace it as a precaution. Another way to check would be with traditional clamps and voltage readers. Would you like me to do that with the MX+? Specially what 12v stats are you looking for... To determine whether the 12v starter battery still has decent voltage? Best Regards , GJ
Battery state of health BOH are tests used for both the car batteries . The 97% you have quoted would be about normal for the 12v battery. are you sure you are measuring the right battery .
My SoH statistics show up right underneath DC battery capacity 47,78 kWh in another test. Then right underneath is the Zoe DC battery State of health showing 90,19% in another reading I did. Although 12v could be read with the OBD I would still recommend a separate reading device with clamps on the 12v battery poles when car has been left idle for some time. What do you think can you get reliable readings for the 12v with the OBD only? I always drive around with a 12v battery booster just in case I long trips. Will be replacing my 12v now in my opel ampera-e as the car is almost 5y old
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€ !?!
Hello unfortunately I don't know this but I'm sure there will be people here who commented under my video that know and will comment I hope to help you with this. Let me know and please share if you know. One could also mention that the range has dropped and less battery SoH during warranty period and maybe then they will do it for free? I will try this trick during next service interval 😁
It was free, but took time and effort to convince dealer. The symptoms in my case, May 2020 Zoe were: 1. Low SOH like 88%, 2. Lower range, 3. Huge time to reach from 99 to 100% SOC (like 30-45 minutes..), 4. Huge predicted range change between 99 to 100% SOC. All these reported and documented issues helped convince dealer to apply BMS update. After BMS update SOH went up to 96%, and range went up and charging from 99 to 100% SOC takes just couple of minutes. Good luck
@matejmraz8122 Thanks for sharing. Great to see the improvements after the update!
Hi,did you already have an BMS update?
Hello Josh, I havent checked yet the BMS version in my wife's 2020 Renault Zoe, but I'm going to do that one of these days with the OBD reader, then check online in the spreadsheet I found if it is the latest BMS. If battery SoH is again like this, I will approach Renault Zoe to update the BMS of this is not the most up to date Version in the car. I guess this would be the best way to approach this, what do you think? Have you had a drop of range and then did a BMS update that improved things?
@@maximaalski Hi,i have also a drop of range,i don’t know the SOH,i will ask the dealer soon for a check up,did you see this one; czcams.com/video/iA3p7p3AF60/video.htmlsi=lPpH2Mg5ANLkWpMQ
Or i will buy a obd so i can see for myself,thanks and stay sharp
@Josh-du7ij Thanks for the video, I will watch it today. Yeah can highly recommend getting an OBD they are great for checking stuff and can even get you out of trouble resetting a code if you get stuck somewhere. Let me know please if you had a good feedback and experience with the dealer and what your strategy was convincing them to do the check. Good luck!
@@maximaalski ok,you will hear me when i know more.
bought from Norway 94500km SoH 98%, now 96000km SoH 94%, with the onset of cold ,Soh decreases? ze 22
Hello thanks for your experience. I honestly don't know but in a previous comment someone named Alper made a good suggestion to drive the battery all the way done to nearly zero and then recharge it to 100. Maybe I will also try this before I do more measurements
For me, the "state of health" option does not appear in the "all sensors" list
Hello, what car do you have and did you search for "health" only?
@@maximaalski I have a zoe. Yes, I tried to filter by the word health and the option does not show up
Sorry to hear that. Maybe something updated in the app that I have suggested in the video. I will try again myself soon to see. I can also recommend the CanZE app that a lot of Renault Zoe drivers like and also allows you to view OBD data via the dongle
@@maximaalski ok, thank you!
Ze40, after 8 years, 110.000 km, 81%
Impressive Zoe driving! Do you find the range reduction an issue or are you not that bothered by it? I recently charged to 100 and drained to zero and then again to 100 and got quite a bit of range back 👍
@@maximaalski I use it on urban and interurban trips. The autonomy it provides me is more than I need. I can also enter the city center and park for free or with significant reductions.
Zoe from June 2022, now 23000km, SOH 97,2%
That sounds like she is one very healthy Lady 👍🚙
What the name of the app?
Hi, the app is called Car Scanner ELM OBD2 and can be found here: play.google.com/store/apps/details?id=com.ovz.carscanner . Hope this helps!
92% after 4 years - 57.800 km - ze 40
Thanks.... That sounds more or less what others have been saying and I've read. Has your expected range also gone done you think or haven't really noticed that?
91% after 4 years and 5 mounth - 87.200 km - ze 40
Thanks for sharing. That's a decent amount of kilometers. Based on what I'm reading this seems "normal" something around that number of state of health. You have almost same number as my wife's Zoe. I wish it would just be a 100%. Have you also noticed the almost 10% reduction in range or not really?
no. because i learn how to drive. and i use for summer MICHELIN
E·PRIMACY tyer. i usualy use 11 kwh charge. summer consumtion 10.9 . winter 18@@maximaalski
Its soo funny how you keep saying "ODB" instead of "OBD" :D :D :D hahahahaha ....but good advice. Cheers
Haha, yes I noticed this too. Very difficult I finally got it right but now the video is already out there. Glad you liked the video. I love having an OBD available in case I may need one 👍
Toyota Aygo no loss of range in 13 years......😮
Haha 😂 Yes Barrie thanks for rubbing that in 😉 But you are very right! Current EVs are really great but this uncertainty about how battery will degrade and hold up over time really needs to be dealt with by the industry. If you read the guarantee most ev companies say something like 80 degradation over x amount of years. If you ask me it should be no more than 10% or rather zero like with regular cars.
LOL BLATANT LIE NO BATTERY WORKS AFTER TEN YEARS

Needs a BMS update for sure!
I think so too... Getting it later this year when up for maintenance. Did you get it too?
That's French quality. Should have bought a honda or toyota.
Maybe.... But this lithium battery degradation seems to be a real problem for all car manufacturers. I think it is misleading.
@@maximaalski You are right. But i think the problem is that most people with an electric car drive 50 miles a day from house to work and back. That's let's say 10% used. Still, people see a free chargepoint at work? Plug it in. Juice up to 100% again. Back home with still about 90-95% charge on the home charger. A trip? Turbocharge in 30 minutes. I say, if it's bad for your phone, it's bad for your car. Same batteries, just a lot bigger.
Hmmm, volgens mij had ik ook in Nederlands kunnen reageren. 🤔
Ha, dat klopt inderdaad! Ja ik begrijp je punt. Wij zijn gek op onze elektrische auto's, voelen ons alleen misleid doordat die standaard Battery degradatie plaatsvinden. Ook al is het binnen het acceptabele niveau. Met een brandstof tank had ik niet na 3 jaar 10 procent verloren. 10% op een relatief gemiddeld bereik van 350km is 35 km bereik eraf. Ik had verwacht dat dit soort cijfers pas na 100.000 km zouden optreden, niet al zo snel!
YA THESE EV CAR VAPE BATTERYS ONLY HAVE 1000 CYCLES AVOID
1000 cycles and then what happens? Will I loose more range?
@@maximaalski KABOOOM !!!!!
