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.

8 Comments on “Battery Health Status

  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,


    • You might have more input from the 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.



        • 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

  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.
