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.

    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...
