Range

It is likely to keep building ( to a point ) but it’s a “Unicorn” figure anyway.
To burst the bubble, next time you boot up the car to the “Ready” condition, before you move off, just reset both of the trip meters, by using the up and down arrows on the left hand side of the steering wheel.
When you reach the “accumulative” trip figure ( shown on the dash panel ) press and hold the OK button, situated between the up and down buttons on the right hand side of the msteering wheel.
Now watch as you get a reality check, on the predicted mileage ( range ) lost, it resets itself.
The predicted 219 miles of range, will be reduced to around 160 ish miles of predicted range, in seconds !.
Before you have even left your driveway.
I am quite aware of how to reset the accumulative and current trips, and the effect it has thank you. As I stated just a bit of fun and fully aware it's a 'Unicorn' figure (as stated in my post that you quoted).

The OP asked a specific question, to which I replied. :)
 
Just balance charged: 449v 199 miles range, reset the accumulated total, it now reads 171 miles.
my accumulated total was 4.3 miles per KW.
!st full charge since recent BMS update

I suspect that the 171 figure it is now reporting after the accumulative trip reset, is when the car is in ECO mode then @Phil Hayward .
With the latest BMS update, after a full charge, your HV pack voltage should be around 448 - 450 volts and the predicted mileage range on the GOM in the NORMAL default drive mode, should be around 163 miles.
When I received my car back after the update in January 2020 the voltage was 449 and did see 450 volts on a couple of occasions.
The predicted range after a full charge and balance fluctuated a bit, but was around the 161 - 162 mile mark.
Now six months latter, the predicted range still fluctuates, but can be around the 157 mile mark now.
The car is now 18 months old and covered almost 13,500 miles.
It drives absolutely fine ( touch wood ).
When commencing a longer journey, I like to reset the accumulative trip recorder before setting off, because I personally don’t like the way that the accumulative trip does not reset itself, like it did before the BMS update.
The higher unrealistic and predicted range reported on the GOM can leave you into a false sense of security with regards to your actual travelled range.
Having the GOM displaying a predicted range of 200 miles may look great ? in theory, but as we all know that figure is not achievable.
Resetting the accumulative trip counter gives a much closer predicted range of the car in my opinion.
I just can’t understand why they though having the GOM report this inflated figure was a good idea over the previous set up ?.
Hey Ho !.
Such is life I guess.
 
Does the accumulative trip reset itself after a certain time/mileage ?
I had never reset mine at all, but when it came back from the 1st service it was reset.

Not that I am aware of ?????.
It just appears to build up a memory of the previous journey’s and then averages out the consumption / miles covered and then predicts an inflated range on the GOM.
This was not the case when running on the previous OEM software.
Resetting the accumulative trip ( or not ) left the predicted range on the GOM untouched, and petty solid in its values.
Don’t laugh ( Please ) but this could be seen as very crude way of detecting if you have the original OEM or the latest BMS software !.
If by resetting the accumulative long term trip on your car, the predicted mileage on the GOM does not alter the predicted range on the GOM, then you have the OEM software installed.
If the car is reporting high predicted range on the GOM ( over +200 miles ) and then you reset the accumulative trip recorder and the range then reduces down to a more realistic figure, then you have the latest software ?.
This strange phenomenon on the accumulative trip, only appears to be present AFTER the latest BMS software has been installed.
It’s no big deal really, but you just have to be a little careful that you don’t regard this +200 miles of range to be “Real” range.
I left my accumulative trip alone for a few trips, just to see what would happen.
When the car was fully charged, it was reporting a predicted range on the GOM of around 210 miles !.
Then on our next longish trip, I kept an eye on the reduction in the range on the GOM.
It appears to reduce both the GOM range and the white bars on the battery gauge a little faster.
At the lower end of range and white bars of the battery gauge, do reduce faster.
I do see that this could catch somebody out, who has not lived with the car for a while and understands what it can and can not do !.
I find myself resetting the trip more often for longer trips, when I intend to stretch the range and return home without charging.
With the accumulative trip meter reset, I am more comfortable with the cars prediction of reported range on the GOM.
I guess this comes from having the benefit of owning the car for 18 months and being able to cover 13,500 miles and sit out two lock downs in Wales ??????? !.
I had a PHEV for over four years with a very limited electric range, so the ZS EV is my first all electric car.
It did help to understand just how far you can go on pure electric range.
All be it with a small range and the back up of a ICE if I got it wrong !.
I find you just get a feel for it after a while.
The HV pack is fairly similar to an ICE car with a small petrol tank in a way ?.
Once you get use to what it will and won’t do and don’t push your luck, it’s just fine.
