battery state of health

State of charge (SoC) quantifies the remaining capacity available in a battery at a given time and in relation to a given state of ageing. It is usually expressed as percentage (0% = empty; 100% = full). An alternative form of the same measure is the depth of discharge (DoD), calculated as 1 − SoC (100% = empty; 0% = full). It refers to the amount of charge that may be used up if the cell is fully discharged. State of charge is normally used when discussing the present state of a battery in use, while depth of discharge is most often used to discuss a constant variation of state of charge during repeated cycles.

    Goodbye…

    So, it’s goodbye to my FL5. Collected today and replaced with a nice shiny IM6 LR. My 5 has been faultless over the 35 months and 63k miles. The only issues have been solely user error. But it’s too small in the back now for my 6ft3 son. Battery SOH down to 93.47%. At 1 year old it was...

    Do not trust SOH. Interesting point. Kia discussion not MG.

    Charge calculations NMC

    Hi all, I'm just trying to understand my most recent charge today. I charged from 25% to 80%, so 55% added. According to MyEnergi app, this was 33.53kw used at the wall which is roughly 55% as expected with a stated SOH at 96% at my last service in December 25 or 61.44kw. However as far as I...

    ZS EV First Service Battery State of Health?

    Just had my first service carried out on the ZS & everything is fine. My battery SOH is showing as 100% which of course is very pleasing & tbh I was expecting. My dongle showed this prior to the service. Out of interest I'm wondering the following; Firstly, just how many of us get a 100% SOH...

    Is this SoH OK?

    I bought a 71/2022 Mk2 ZS EV about a year ago. I have just installed the eZS app (great app!) and it tells me that the battery SoH is 85.4%. Is this normal for a 4-year-old car?

    New Owner - 2021 MG5 SR

    Hi everyone. I've had my 2021 MG5 SR for nearly a week. Got it from Cinch and part-ex'd my 10 year old Leon. I'd watched a load of Youtube videos and paid for a carvertical report, then pulled the trigger! Loving it so far and it's far exceeded my expectations. One previous owner, 44k miles...

    SOH report MG4

    My MG4 L/R was in for 3rd service and MOT 2 weeks ago. When I checked the service report properly at home I noticed the battery state of health was hand-written in biro at what I think is 96%. I thought I would get a "proper" report not just this. I contacted the dealer and they replied "so...
