I have to ask, but why would a brand new ZS need balancing on it's first charge? the dealership would have charged it on a 7kw before handing you the keys so would have been balanced before you picked it up...
Well, I wanted a full charge for a long journey ahead the next day - so I wanted it to get to 100%. Once the battery reaches 100% I believe it effectively starts to balance itself - which isn't a harmful thing as far as I know. So I didn't need to balance it - it was just going to happen if I stayed there long enough.I have to ask, but why would a brand new ZS need balancing on it's first charge? the dealership would have charged it on a 7kw before handing you the keys so would have been balanced before you picked it up...
you can charge to 100% on a rapid charger, the car will slow the charge rate down as you get nearer to 100%, it's not quite the doomsday scenario that some would have you believe. Balancing is not harmful you are right, but it is only needed every now and then.Well, I wanted a full charge for a long journey ahead the next day - so I wanted it to get to 100%.

As it happens, 6.5 hours later, the car was at 96% and the charging had stopped.
BTW - on my old leaf - the charging connector can be set to auto release after a charge has stopped, allowing others to use the tethered cable - this doesn't seem to be an option on the MG.
If someone’s car was at 100% and unattended, and I was able to unplug, I absolutely would - in the highly unlikely event that my car was in this situation, I’d be happy for someone else to unplug me. If damage was caused, whether due to unplugging or bashed in a carpark, etc - I’d rightly be annoyed.you can charge to 100% on a rapid charger, the car will slow the charge rate down as you get nearer to 100%, it's not quite the doomsday scenario that some would have you believe.

To be honest I don't think I would be very happy knowing that someone else was going to be unplugging my car (whether finished charging or not), I get quite precious about my vehicles and someone else touching it without my permission is a huge no no in my books.
Nah - most don’t so a moot point. But, I think legally they all should. You’re essentially in a contract with provider whilst charging, once you reach 100% then I see that as an end stage where your car should release the leased connector.Does it release the CCS plug when at 100% on a DC rapid charger ?
While i agree, i have not seen a lot of chargers where it would actually be possible for someone else to park in a way, that made it possible to use the cable.Nah - most don’t so a mute point.

Just an opinion though ?![]()
Actually, one non-rapid charge is probably not enough to completely balance a car that has spent weeks on a boat, perhaps a week at the dealer, and who knows how long in China waiting for parts. Especially as the dealer probably doesn't have the time to let the balance complete.the dealership would have charged it on a 7kw before handing you the keys so would have been balanced before you picked it up..
Balancing ensures that each cell is at the same voltage level as it discharges, or at least close to the same level.Actually, one non-rapid charge is probably not enough to completely balance a car that has spent weeks on a boat, perhaps a week at the dealer, and who knows how long in China waiting for parts.

But a new car hasn't had much of a chance to balance the cells at all. All the cells are likely manufactured on the same day, but there are still inevitable variations in cell capacity and SoC.A battery pack standing unused at around 50% for a few months will not cause much of an imbalance issue.
