We are trying to find out what handling is the best for our batteries, thus we are happy about each costumer that gives a feedback about his car.

About the Zoe battery

The Zoe has a 26 kWh battery pack (rated capacity), see this document, page 60: 12 modules * 16 cells * 3.75 volt * 36 Ah = 25.92 kWh. However, it’s life would be severely shortened if using that capacity. The BMS caps the capacity by roughly just under 10% on both the charged as well as the discharged end. This saves a lot of battery stress but reduces the capacity to a usable 22 kWh. If you want to know more about how these type of cells should be treated, here is a good link.

  1. I have a ZOE R240 with less than 40000 Km since nov. 2015. Unfortunattely I had an accident, (heck damage). According to my own measurements: SOH 98%, max. delta cell voltage 10mV . Renault car dealer (ZE base !) is taking in account “internal consideration” and classifies the battery as defective. They “cannot” tell me WHY because of “data protection reasons”. I love my car and I don’t want to give up.

    Does anybody have experience with this ? Any hint is welcome.

    Regards from Stuttgart,

    Lucian

    • You might have more input from the goingelectric.de forum. My opinion only (I have no experience with this) I assume your battery is rented. If Renault wants to replace it, I wouldn’t object. If you own the battery, the decision is up to you I would think?

      • Hello Jeroen,

        yes the battery is rented and my first step was on that forum. The crux of the matter, till now all happens on my own cost.

        Regards,

        Lucian

        • There is not much I can say, other than that the battery is VERY well protected against damage. Personally, I would take it to a body shop and be happy with it, but that’s me. I always take the dealer’s advice, but not if they cannot explain it. Good luck Lucian.

  2. Nick: Niels
    Purchase: 2017-04
    SOH: 95 (i caught it changing from 96 to 95 close to home, within approx 2 minutes, charged to 100% including balancing, did not change the value.)
    Measured: 28-11-2019
    Charges/week: Variable, 1 full charge on average (previous owner 1-2, estimated about 1.6 full charges)
    Charging speed: Usually 11, sometimes rarely 44 or 22 kW. (Bear in mind drove this car for less than 1000km at time of measuring. I know the previous owner often used 44 kW chargers and charged with 7 or 11 kW at home.)
    Place: Previous owner often in the open, me in the open
    km: 43882
    Car: Zoe Q90

  3. Hi everyone

    What exactly does Battery Health Status mean.
    The table shows some examples where Battery Health Status is greater than 100%.
    Honestly, I thought a perfectly healthy battery had a value of 100%.

    • Almost certainly (I am careful with absolutes), 100% means 100% Ah capacity, with reference to the nominal capacity. In real life, most batteries are delivered 1-3 percents above nominal, I assume to keep production failures for low capacity extremely limited.

  4. Our 22kwh kangoo van shows a state of health of 82%, however this does not seem to check with our usage experience.
    We have a mains power logger which shows that the charge rate is 3.7kw.
    From empty (performance limited) to fully charged takes 4h28m 16.5 kwh
    So 3.7*4.47*100/22 gives 75% battery health.
    This assumes that the charger Power Factor is 1, but per your charger efficiency page, at 16A effiency is known to be about 80%, so my real available power is really only about
    13kw.
    This correlates well with our real experience, from fully charged to flat is only around 13kw (from the vehicle display)
    This is also backed up by the fully charged range/economy figures (miles) 49/3.5 = 63%

    So it seems to me that the Renault figure is total imagination

  5. Hi

    While I was at service center on the beginning of October this year to fix preconditioning issue on my ZOE 50 I asked technician to check battery SOH.

    It showed only 94%, which surprised me a lot, as the car is only 8 months old, and I charge it mostly with 8 A once to twice a week to 90 – 95% SOC. Only once up to 100 %.

    So, here are my data:

    Nickname: Ivan
    Purchased: 2020.02
    SOH: 94
    Measured: 2020.10
    Charges per week: 1-2
    Charging power: 1,76 (220 V @ 8 A Granny cable)
    Charging place: outside
    Km ( x 1000): 005
    Car: Zoe 50 R135

    And BTW, preconditioning was not fixed.

    Stay healthy.

    • I don’t have personal experience with a ZE50, but that SOH for such a new car seems very, very low to me. Most batteries are delivered with a 100-104 SOH and degrade very roughly 2-3% a year. Personally, I would call Customer Service and ask them to make a note of it in the file of your car for warranty reasons, and ask the dealer to do the same.
