I am confused.
After a full charge my battery shows 439v and a displayed 169 miles of range in 'N'. I had comfort 2 carried out in December but I think I need the latest (15-01-2021) BMS update to get to 450v.
When I had the updates carried out in December my range dropped to a poor 125 miles in 'N' after a full charge. I recently reset the m/kWh cumulative and per trip and this increased the range to 169 miles at full charge.
My car goes in for service next week but I am unsure if I should request the latest BMS update as the range is back to 160+ miles, were it was when I bought the car, with pre comfort 2/BMS update.
Any advice?
If you are only getting 439V fully charged & balanced, then you definitely have the problem BMS and you need to get it fixed by the dealer ASAP before it gets even worse and takes even longer to get back to full health.
I am inclined to agree with @JodyS21Very interesting.
Sounds likely a lot of hearsay than what Dr Dave has actually said about his car.
His car has not had the faulty update.
So why will he suddenly have a problem which is due to this faulty update?
439V will be about 125-127miles in the original settings so the most likely explanation of the figures Dr Dave gave is a delayed reset or other very simple explanations rather than assuming that @Dr Dave somehow has developed a problem that occurs with a particular software update that he clearly has told us has not been applied to his car.
@Dr Dave clearly states 439v after full charge. Anyone who has been following the BMS story, which doesn't appear to be @KasEV, knows that 439v is neither 455 or 449/450v, the only acceptable voltages after a full charge and balance. He also says 'when I bought the car, with pre comfort 2/BMS update'.
@Dr Dave also states that after resetting his cumulative the range miraculously went from 125 to 169 miles. Something @KasEV says should not happen as GOM is based on the last 10 miles or so not the driving history.
So not really hearsay, it was actually what was written.
