   May I suggest another keyword? A factor of importance might be the general cycle depth. My car for instance is always charged at night, but often runs only a few 10ths of kilometers a day. I would call that “shallow cycle”. People doing a 95 km one way commute every day, charging at work, I would call that a “deep cycle”. Word in the street is that deep cycles are a bit better for SOH.

   Using field “0x7bb, 80, 87, 2, 1, 0, 10, Bat SOH%3ld.%01ld, %, 0x2161, 0x6161, , 1, 0, 0\n” it is possible to get 0.5% precision, like 90.5 91.0 91.5, but no more than that.

   You can also compare health by Capacity in Ah, but it’s not Renault’s official measure for battery changes.

   Cheers Alexandre, I was wondering if my battery was closer to 99% SOH because I can get really good mileage.

   One thing I have noticed with the software (while testing a 43kw post) is that it still says 1 phase even though its a 3 phase connection.

   I’ve already been able to evidence a brand of charger (evolt) which is held back to 17kw when charging on AC instead of (siemens comparable) 40.4kw (on an equally low SOC battery).

   Great software, keep up the great work.

   You can easily see if the charger is holding back or the car is. “Available charging power” is what the charger is stating as max. “Max battery charge/regen” is what the car can absorb given the SOC, temperature and maybe some other black magic. Some fast chargers, even wehn not load balancing with other cars being charged, have a nasty habit of starting low and then slowly “turning up the volume”. This is rather “not done” IMHO when you have to pay by the minute.

   Some people suggested to crowd-sticker chargers “checked by CanZe: xx kW”, hehe.

   AFAIK Tesla and Nissan state their capacities in rated kWh, while Renault is “too honest” and states usable. In all fairness, in the Tesla you can “emergency use” most of that excess with a manual override.

   Hallo Zusammen,
   hier die Beobachtungen zu meiner ZOE.
   Gekauft 06/2013.
   06/2013 0km 100% (Hoffentlich)
   07/2014 13400km 98% Renault Batteriereport
   12/2014 18800km 96% iCarsoft 907
   02/2015 21150km 96% iCarsoft 907
   04/2015 23960km 94% iCarsoft 907
   10/2015 31263km 92% iCarsoft 907
   Ich lade 1-2 mal pro Woche meist mit 22kW. Im Sommer lade ich mit 7kW
   wegen des Lärms der Klimaanalge zur Batteriekühlung. Der Wagen steht immer in einem offenen Carport.

           Thanks for the heads up and most appreciated 🙂 We have discussed this amongst us just a few days ago. While we most certainly do not dislike money, there is a feeling that for the probably relative minute amount that would come in, the risk of getting into an argument about it is simply not worth it. Maybe we will change our minds 😉

   For remark:

   Datas were taken after using the whole capacity-range of the battery for min. 3 times because of having some long runs to handle.

   When using only 50% of capacity-range for a longer time the datas for capacity is still smaller. I think the BMS can only calculate a correct capacity when discharging the battery down to warning because the discharging curve is not linear….

    Hello team,

    here are the current health states of our two Zoe cars.
    THellweg – 2014.08 – 94% – 5-7 – 22kW – open – 35tkm – Zoe (210white)
    THellweg – 2015.12 – 96% – 5-7 – 22kW – open – 11tkm – Zoe (210black)

    Remarks:
    The white car was ordered as a new car so its manufacturing date will not differ much from the purchase date.

    The black car was purchased in december 2015 with a mileage of 7tkm already driven – but it is a 2013.05 model.
    Here are the details:
    Before we bought it the car was used as a demonstartor and rental car (for customers) by the car dealer.
    It´s real fabrication date is 2013.05 (the problematic period) and indeed – serious charging problems occured after some time.
    Therefore the car dealer installed a new motor, a new charger, a new batterie and an new TCU in 2015.05.
    We were told that the displayed mileage of 7.4tkm is from the period 2015.05 until 2015.12 when we bought it.
    The batterie health was displayed with 98% in december until it decreased some days ago from 98% directly down to 96%!
    I drove 3.5tkm with it from the end of december till mid-february and charged 5-7 times/week with 22kW.
    This is the same mileage than before with the white one that is now driven (with fewer mileage, 1.2tkm/month) by my wife.
    I was surprised that the health state jumped down 2% at once and now I´m concerned that the health state will continue to decrease so rapidly. But most confusing of all for me is that I see a lot of cars in the list with more than 100% health state.
    Maybe this health state parameter is made of 50% “black magic” !?

    All the values are taken with CanZE.
    Thank you for this great software product!
    Cheers,
    Thomas

    Hi Jeroen and all team,
    thanks for the very useful app. I even bought a cheap Android tablet for it (and only it) and love using it on longer travels. I love especially the consumption screen. Now, since you’ve announced that Frédéric is building up CanZE for iOS I just can’t wait to have an early alpha installed and tested. The WiFi dongle is already on it’s way from China… 🙂

        Not really. I tend to charge twice a week, although it’s a full charge from low SOC.

        I’ve also go on long trips occasionally which may need 10 rapid charges.

        Having dropped to 91% it’s now recovered to 92% and seems to be staying there.

    Rapid is 43 kW ? How many such long distance trips per year ?

    Seems the SOH estimate is not necessarily reliable: I’ve been reading of a test with 75% SOH and still 22 kWh available when actually making a trip (in spite of 17,5 kWh capacity announced).

    Maybe only 2-3 a year, but as much as 500miles at constant 70mph (other than stopping for charge)

    My car now shows 21.6kwh but I just covered 122.6miles on a single charge and yet I used 23kwh (no charge top ups).

    My actual regen per charge now seems to have gone up a lot too. Used to be 1kwh per 22kwh but now more like 4kwh per charge as regen.

    The battery of my Fluence ZE which was at 84% SOH last year is now at 76%.

    It was 75% in july, but … I did not used the car for a dozen of day this summer and the SOH came up to 94% .
    It took three weeks and more than 500 km to go back from 94% to 76%.

    Zoé (Q210 with 43 kW charger) purchased Dec. 2014; now 17500 km; typically charged in an open carport with 22 kW, 3-5 times a week.
    SOH Level is at 72% now.

    Ist the SOH Level critical (battery is coming to an end) or directly linked to the temperatures we have currently (-10 °C in southern Germany)?

      Hi Bob,
      Just to give a short update on what happened meanwhile.
      I came in contact with the next authorized ZE station (Bellemann, Speyer) and they performed very well. They confirmed the SOH value and managed the BMS update.
      Now, the SOH is 99% and I am enjoying 40 km more to drive.

      Thanks to you and the team for programming this nice CanZE tool.

          Hi Francesc,
          Greetings to Spain.
          Yes, after the BMS update I was able to (re)use the full capacity of the battery which result in 40 km more driving range (compared to the previous level; not the conditions I had when purchasing my ZOE).
          Prior doing the update the dealer had to ask Renault for authorisation. Any kind of update looks like an individual activity. No general announcement from Renault to ZOE owners to do the update known.

          Best regards

    Got my ZOE 2 months ago. SOH 80%. Just did a range test and achieved 181km. According trip report: Consumption 22kWh, saved: 2kWh = ca. 20kWh usable battery capacity

    Previous owner charged with most of the time with 2.3kWh, not known how often per week, the supposed data:
    evzone 2015.06 – 80 – 2017.05 – approx .3? – 2.3 – carport – 18 – ZOE

        From what I heard (but I am not sure this correct) Renault informed it’s dealers that the update should be applied if AND ONLY IF:
        – balancing (99% to 100%) takes a very long time;
        – battery degradation seems extremely fast

            So far only carried out a few shortish trips.

            With roofbars fitted I got 44miles on 11kwh. So it does seem range has increased.

            Roofbox fitted now so I’ll get an idea this week if range has increased, but I expect the roofbars and box to knock about 10miles off range.

        I think we can nullify this item. There is new software for the battery that completely changes it’s behavior. I’ve seen 20% jump of the SOH. There was obviously something not quite OK with the old firmware and I also think Renault dares to push the edges of the capacity a tiny bit more.

    My SOH bounced back up to 98 for a time but has now stopped at 97% SOH at 36k miles.

    This is a similar experience to pre-BMS. Question is will it follow the same pattern again. I do hope not, I want to be wrong, because if it’s true I’m going to struggle this summer if range drops.

    Dear Bob,
    why is there a difference of 2° between the midtemperature of the heatmap and the charging history.

        I refer to the circumstance that f.e. the heatmap show 26,75°(midterm,3 of 4 with 27° and one 26°) in the last moment bevor shutdown (battery full), the charging history then make a entry with 24°..

          Okay, I see. This comes probably due to the fake that these values do come from different fields provided by the car. So we can conclude that these are different sensors too.

            That means that the only way to get the better information is to try both values and look which gives the higher range.

          • Bob Fisch says:

            August 17, 2018 at 3:47 pm

            No, that means that the two different sensors at probably two different locations are being read out.

            The values from the heatmap come from the different cells.
            The other value comes from another sensor – were the location is not known – and which gives the temperature of that specific location. I could imagine that this is outside the battery shell, whereas the cell values are measured inside.

            Dear Bob,
            I Think that I know now the meaning of the temperature in the charging history.
            It is the average temperature of the battery when you begin charging.
            This is helpful for me, because i can influence this value with special hardware.
            Thank you so much for your work and your time.

      That seems awfully low. Did you have the latest LBC software applied? Check in firmware screen, tap LBC. Software should be 0851 (from memory). If you also have long charging stuck at 99%, make sure you mention that to the dealer. It is the “safe word” for getting the fix and it should be for free.

      Edit: if this is a Fluence ZE you are talking about, ignore my comment please 🙂

    Sandy… Post BMS. Now at 48,000 miles and SOH has now dropped to 93%

    It did bounce up to 98% for a few weeks, 2000 mile or there abouts before dropping to 93%. As I’ve said for a couple of years now I feel the BMS update was just to change charging profile. The big gain in SOH was down to the pack shutdown and restart. And look my pack seems to be following a very similar degredatiob profile as it did pre-BMS.

        Thing is though, you can’t simply extrapolate that. Mine was upgraded 18 month and over 27000 km ago (total just a pinch under 100000 km). And the SOH is 94%. I can’t remember the exact SOH it was reporting before it went in back then, but I certainly remember it being on 86%. I was probably a few lower.

        It had degraded 16-ish percent in under 3 years. Now it has not only reset, but degraded 6-ish overall. I haven’t seen a shred of proof yet that the old and the new lines are converging. The old line would have taken me at roughly 76% by now on a 5+% per year rate. After 18 month mine is still on a slower 4-% per year rate. Diverging still.

        Now we can argue
        1) that mine is a sample of one too, and that is completely fair
        2) “but wait till it will really start to drop you!”, and that is complete silly conspiracy thinking.

        If we want to have this argument in a somewhat sensible way, I would think we need at least a few, preferably randomly picked cars, and we’d need to see the degradation patterns before and after the update.

    48,300 now at 94%. Matches what it did pre-BMS. Now I expect it will drop to 89 or 88% within a few 1000 miles.

    I understand you can’t “just” compare with 1 car. That’s why I’ve asked people on speakev to update their soh findings too.

    It has to be more than a coincidence that my soh drops pretty much exactly mirror that before the BMS update.

          Bounced to 93% for a couple hundred miles but now back at 92% again. Usually the bounce is preceded by a bigger drop in my previous experience. Time will tell.

    I will certainly like to contribute to your table, so please add the following data…

    Nickname – Bahrt
    Purchased – 2018.08
    Battery health status – 83
    Date measured – 2019.03
    Charges per week – 5-6
    Charging power (kW) – 22
    Charging place at home – Open
    Kilometers (x1000) – 8.400
    Car – Zoe (R240)

    … I would also like you to answer my following questions…

    Every weekday my Zoe runs a charging cycle from approx. 20% to 100% (after work)… Having driven 8.400 km, I find it a bit extreme finding the ‘Battery health status’ at 83.

    Question 1:
    Can I use the ‘Battery health status’ value as a percentage of the 22kW to get the ‘Energy available’ value? Calculation: 22kW – 83% = 18,26kW… According to the car, the battery is 100% charged at this point.

    You can see the CanZE data here: https://www.dropbox.com/s/qy68rowz69d8up2/Charging%20%282%29.jpg?dl=0

    Question 2:
    I am a little worried about my battery condition degrading so much already… Will Renault accept to provide a new battery, when the SOH is below 70? The battery is not rented.

    Thanks!

      #1: As far as we know, the SOH is not only the percentage of the available energy, but we have no calculation details …

      #2: If the battery is not rented, Renault will most certainly not replace it, even if the SOH falls below 70%.

      1) Your battery condition is horrific and it has nothing to do with your charging habits at all. I bet you have old firmware. Check the firmware of the LBC and see if it is on 0854 or higher.
      2) Did you really buy an R240 *new* in august 2018? If not, what is the date of new purchase? Same for the km’s. I am not trying to be facetious but at that time, almost all sales switched to R90.
      3) From memory (so don’t quote me on it) the battery warranty for a battery owned model is replacement/repair when under 70% SOH within 5 years / 100.000 km’s, whichever comes first. If your battery is truly going down this fast, and it´s not the LBC bug, and your purchase/km’s are “from new”, you should have no problem claiming warranty.

      For reference (sample of one, I know), my battery is mod 90’s after 5.5 year and 100.000 km.

          Yup, old. 0854 on the LBC is what you are looking for. Dealer will have to do it and because of HV power down it will take about 2 hours. Some dealers charge, some don’t. Your best bet is to tell them “range at full battery is surprisingly low and going down, and the car stays on 99% very long while charging”. Those are the issues in a document to the dealers triggering a software update. I personally have payed about 70 euros for it as I couldn’t be bothered (dealership had been very good to me on another issues I had). Anyway I believe you are still in your warranty period, even if the car is considered second hand but of course I don’t know Danish law on that.

    I realize that I should have been more precise about the purchase conditions… This particular Zoe was bought (by me) after it had been kept as a exhibition car, at the dealers facility since start 2016. Just parked there (inside the building), to be displayed for potential buyers. The odometer was saying 40 km when I took over the vehicle. I payed a fair (I hope) price for this car – approx. €23.000 (incl. the 50% EV tax which we face here in Denmark). I will indeed check the LBC firmware version and report back.

    Thanks a lot btw, for your great effort in bringing this useful software to the crowd.

    My Zoe is a November 2015 model. I bought it in July 2018 and must now renew the battery lease.
    My local dealer measured the Battery Condition (PR144) in February 2019 (18000 miles) and reported 73%. So we arranged for a replacement battery under warranty.
    On the day of replacement the agent called me to say they had used the wrong data to report State of Health and the true value was 100% – no replacement needed.
    So I purchased a Konnwei ELM327 dongle and used CanZE to make my own SoH measurement = 73%.
    I have started the Renault complaints procedure.

    The dealer says the correct data must be downloaded from Renault servers. I have their report showing SoH 100% but Date of vehicle link 30.10.2015 ! The report is marked confidential.

    Winter range has been 60miles (5-10C), summer 85miles (15-20C). This may be normal for a 22kWh battery but why have Renault given me conflicting data?

      My advice would be: check the LBC firmware version with CanZE. If it is below 0854 (and I bet it is, go to the dealer and tell him range on the GOM is getting strangely low and when charging it’s stuck on 99% for a very long time. This is the magic complaints that will make them update the firmware in the LBC and BCB. The SOH is probably in the mid 90’s. As for them having old data: a bit of a BS story as the CLIP tool reads exactly that. They can print it out and send it to CS. They even did that at every service in the first two years standard, at least here. Does your app work? If that’s never been enabled, just maybe the car is not telling big brother.

    Owh by the way, I bought this used Zoe last April 2019 from a Zoe leasing/rental company. It was idle for 2 years! The mileage was around 11,000 km when I took ownership. Battery SoH drops to 75% after several weeks of usage than shoot back to 98% after the BMS LBC update.

    I have determined that my car is an R240 because the VIN contains code B. VF1AGVYBxxxxxxxx. It will only charge up to 22kW.
    However, CanZE returns Q210. When I post my battery data I want to be sure all the details are correct.
    Any suggestions?

        Rot is setting in. 21kwh is the claim at 100% charge. A few months ago it claimed 22.5kwh usable even though I couldn’t use over 20kwh before it kicked in early limp mode.

        Sadly my adventure with Zoe is coming to an end. I expect to have a new EV before end of the year. Hopefully it drives as well but gives me less silly issues in first 6 months and no long term deg concerns.
