For ‘peace of mind’ reset trip info when charged to 100%, the car then computes range with a ‘generic consumption’. Obviously that will change once you start driving.

3 phase AC charging @ 11kWh is about 30% faster, therefore it does make a difference. If it’s worth upgrading to a 22kWh cable depends entirely on how often you think you’re going to use it, although in my experience it’s always ‘better look at it, than for it’..

Your wall box at home is unlikely to be 3 phase, therefore having a single phase cable for daily use is handy. If you intend to use 3 phase AC EVSE’s, buy a second (22kW) cable.

Did your SoH change?

No, but I’m curious to see if an AC charge from below 10% to 100% in one go will indeed change SoH (don’t think to go as low as 6A is actually necessary).

Great top balancing is fine and well, but the really interesting values (for you) would be in the 45-70% SoC bracket?

I’m wondering if you’re up for an experiment (if you have a means of measuring cell voltages using OBD). Charge to 100% (no BMS calibration) and take note of the min/max values, then compare them with what you get after your regular routine.

Charging isn’t 100% efficient but that’s beside the point, adding just 15kWh into the HV battery isn’t sufficient to do a BMS calibration?

Curious, how long does balancing take you if you charge to 100% from let’s say 80% or does it not happen at all?

It’s certainly confusing that the ZS manual seems to use the term ‘equalisation charge’ also for a BMS calibration, but it is what it is, but you’re spot on explaining how it’s done properly. What seems strange though is that MG recommends to do this (on a ZS EV) on a monthly basis? You...

I assume that’s a typo, otherwise you would have barely added 15kWh?

No, the two processes I refer to are a) balancing/equalisation (same thing) I.e. discharging cells b) BMS calibration/battery calibration charge (measuring energy, updating SoH) The latter isn’t described in the user manual I’m looking at, maybe you could post a screen grab of yours?

I’m sorry, but you can’t call a BMS calibration a ‘full & proper equalisation/balance charge’, these are two different processes, with two different goals. The user manual only describes that equalisation/balancing should be done once a month. Maybe you have a different version but the one I’m...

Agreed, but what you described isn’t balancing: Balancing is making sure that all cells are at the same voltage. This is usually done once charging has reached a set level (100% for most, although some models can do this at lower levels). In general, individual cells are discharged until their...

SoH is a measure of battery degradation, balancing will not improve this value. 85% seems exceptionally low for the age/usage of the car, unless it sat for months with either a fully charged or completely empty HV battery? The first thing I would do is a HW reset (disconnect 12V minus pole for...
