This is what they said and is all the information i have..A further update to BMS since 15th Jan? If so would be interesting to know what it fixes or improves over the Jan update.
Wowsa, be interesting to see what this is - if there really is another one.This is what they said and is all the information i have..
What another BMS update released on the 15th Jan two days ago.....really?!Wowsa, be interesting to see what this is - if there really is another one.
Hopefully the very helpful Miles may know.
you mean a couple days ago - 15th febWhat another BMS update released on the 15th Jan two days ago.....really?!
Who knows lol.....Surely not?
I would be extremely surprised if this was the case !.Surely not?
Mine had the latest Jan BMS update and post this had the same symptoms as per DriverInNorway, so wouldn't guarantee this...
I have since had the car back to the dealer who's reapplied everything and mentioned MG had sent a further update out... Hopefully today, I will have the battery low enough to test once again if this fix has resolved the problem or not.
Had a lot of problems after the BMS update in early December - the range dropped about 100 km - the real range after the update remained about 140 km only. Couldn't trust the numbers of remaining km at all. Every day - multiple warnings "Slow Charge the Vehicle" although I have slow charged the vehicle almost every night.I do wonder if something else is going on. Every day I get "Please connect slow charger" which I don't hear others reporting. I only have a granny charger and do regular long slow charges. I also once got "HV battery fault" on screen, but apparently battery is ok and will recover. I've done a lot of charging since BMS update and HV voltage this morning showed 432V, which is up from 429V a week ago. This could take forever...
I'm making progress - voltage has increased from 426V to 446V. I should hit 450V within 2 weeks. I'm still only getting about 90 miles under similar conditions to last Feb where I would get 110 miles. I'm hoping this comes good.Had a lot of problems after the BMS update in early December - the range dropped about 100 km - the real range after the update remained about 140 km only.

The car was at the dealership for more than 20 days, and they did the daily charge/empty cycles - only after 21 days the car was back to normal.

That all looks normal to me based on my last charge which was almost 4 weeks ago. The car has barely been driven since then and I don’t yet have a home charger. A broken right leg has rather put a stop to my drivingUpdate on my experience having been quite badly affected by the BMS in late 2020 and with the Jan 2021 update 'fix' - the max voltage has been stable for the last 2 weeks and 10 full charges at 449.25v The max/min voltages have a difference of 20mv which has not changed and the balance takes 4 hours every night. Is anyone else seeing this? Range is largely back to normal, but could do without 4 hours of balancing charge each night.
I am witnessing a similar pattern.Range is largely back to normal, but could do without 4 hours of balancing charge each night.
I'm not convinced there's a obvious reason for how long the balance takes.I am witnessing a similar pattern.
At my last & balance the HV pack reported 450 Volts, the highest I have ever seen.
The range in the default mode is around the 161 miles mark.
The balancing is still taking between 3.5 and 4.0 hours still.
I have completed about 6 or 7 full charge / balance cycles, after I received the 15.01 BMS update on the 18.01.21.
My HV pack was never affected by the "Buggy" software, it received the latest BMS update because my car was in for the 1st service etc at the time.
