      As promised, before charge: And, after - no equalisation: No improvement in SoH, as that only seems to happen with the...

      Interesting. There is at least a lot more understood now than there was back in 2011 when I started long term testing and BMS design for...

      As you have no idea which of these faults is current, start by resetting the codes then wait and see which (if any) return.

      Not quite sure that you have quite a full grasp of EV batteries Mickey. No disrespect intended. However, in response to your question...

      My understanding, which is from LiFePO4-based home energy storage balancing (so may be different with EVs) is that balancing is based on...

      Cell voltages determine state of charge. I think you are going wrong because you are assuming that balancing brings all cells up to the...

      That's perfectly correct Everest. Good info.

      The BMS will use coulomb counting, rather than voltage for SOC calculation. Because the upper knee on LFP cells is so steep the delta...

      For NMC yes, but with LiFePO4 cells you'll often see bigger differences at the upper knee of the SOC-voltage curve.

      Mickey, you are over complicating this. doubledroz has already stated he has been unable to carry out an equalisation charge on his 3yr...

      Hi Mickey, no it's not concerning. A proper full equalisation to 100% doesn't harm the battery. Even NMC is fine with this, they are not...
