On the theory that the BMS will allow the battery to run down to a lower voltage after the update?

More an open question rather than a theory.

Before the update turtle hit at 3.43 and after at 2.56v


hmm.... so, after the fw update, turtle more may degrades the pack faster.... :?:


:lol:

Yeah... we can assume Nissan did something that outtrumps trump's stupidity which seems to be the norm here

or

we can simply consider the outlandish thought that the BMS is still adjusting to new pack parameters.

Hi so I went to Yorktown heights Nissan and got the recall done, they also did the SOH. I have a 2017 SL Its 1 year old.

The SOH paper came back at 82% and I was a disappointed that it wasn't higher. I park in the shade and do everything I can to keep the car cool.

Anyone get such a low score ( percentage after 1 year) 82%?

Funny thing was I got 5 stars in the 3 categories.

Now with the update: It definitely seemed to be more accurate with the range. When I charged it to 98% it had a range of 111 and I did close to that.
Thankyou,
CS

if u got 111 miles on a charge, I think you are a bit more than 82% SOH
