You've not got the obd2 thing have you?
It would be interesting to see your min and max cell, then you'd be able to see if it's back in balance.
Did you do an accumulated trip reset? before getting your 154GOM in N3.
I get 163 if I reset Acc in N3 - which is........yep the WLTP range.
No - You are correct, I do not have the OBD device.
I did perform the accumulative mileage reset after receiving the car back from the dealer.
It did increase the predicted range instantly.
They ( the dealer ) did not perform this reset.
When I picked up the car after the Jan 15th update, it reported a voltage of 449 V ( briefly flashing to 450 volts ) with a predicted range of 162 miles on the GOM in normal default range.
But, further full charge / balance cycles after have reported similar HV pack voltages, but the predicted range is a little less.
Hard to say if this has been caused by journey type or demands on the system etc.
The weather conditions have been cold, and my old bones really like the the heat.
Therefore, the HVAC settings have been set pretty high on every single trip lately.
Prior to the car having its first service / BMS update, I would only charge the pack to the full max level, IF I had a long journey to cover the following day.
Normally, I would charge to a SOC that would suit my needs for the upcoming trips in the following week.
E.G :- So if my trips over the next few days where only small ( Due to C19 etc ) then I would only charge to about 80% of the capacity of the HV battery.
Therefore only charging to about 100 - 120 miles of range of SOC, so charging to about 80% on the GOM would meet our needs just fine for that forth coming weekly trips.
So, over the last 12 months of ownership, it is very true to say that the car has only EVER been charged / balanced though it's full cycle ........ about 6 - 8 times in total max.
I was never in the habit of charging the HV battery to the full point of bursting, just to make a small trip to our local super market trip once a week - why would you ?.
Therefore, it is true to suspect that my HV pack could have well been a little "Out of balance" prior to the update ???.
Question : - Who the hell honestly checked the voltage on their HV packs after a charge before tall his crap kicked off.
Nobody - is the answer !.
Now it has become an all consuming passion.
Hand on heart, I have no idea what my HV pack voltage was prior to this problem inflicted by the so called "Buggy" software thing.
I really don't think my car was ever affected by it anyway.
I just simply understand this, prior to the first service I had a car that I could simply charge and use. It would give me a pretty good return on the estimated range, to the distance covered in actual miles.
NOW - ( like a few other owners ) we have absolutely no idea what the hell is going on !.
The factory OEM software, complete with it's crazy bongs was hard to live with - right ?.
But it was stable, but now post BMS ( so called ) "improvements" has caused more issues that it has cured in my opinion !.
Only speaking for myself here, after owning the ZS EV for 12 months and 9,000 miles covered, I really had GOOD handle of what this car could return, in regards to distance covered vs the predicted milage on the GOM.
It was pretty much bang on - one mile of range used was one about one mile of range covered.
Now, I have no idea what the hell is achievable !.
A so called "first Service / Improvement update" has caused this problem, pure and simple !.
No wonder owners are frustrated and angry with the whole situation.
Somebody has screwed up here BIG style for sure.
Left a massive hole to “back fill” with owners that's for sure !.
