Cold weather battery mileage state (MIC model3 SR+ 2021)

[Mr Gus]

Reporting this to the forum as the media on the new battery chemistry is one whereby it says its more prone to cold weather range loss than regular li-ion

Well, it is hovering between 1 & minus 1c according to the external sensor (sunny day) at 10.30 am ..the interior of the car was at 5c having done a school run this morning (several hours before) & been defrosted (ice, ice baby) at around 7.35 am

Range on the app is reported to be 251 miles capability at 100% SOC (it was on 83% pre-heating to go out & give training)

No drama right?
Whilst I know this isn't the extreme of Joe / Aberdeen / Edinburgh / the Highlands & islands it does give an idea of "first winter" in a very wind blown edge of the fens new battery chemistry real world potential / scenario.

Will log a few this winter temps & range notes as it looks like this chemistry will be more widespread in upcoming vehicles.

The Model 3 now of course has heat scavenging via the octovalve and heat pump which makes it much more efficient in cold weather than the previous builds.

[Mr Gus]

Question is dan, if the gen 1 nissan leaf circa 2015 had it, then why were tesla so slow as to integrate it? (octo-pump or otherwise)
Suffice to say a smaller capacity battery, + the "unproven" chemistry = media reportage (questioning thru negative, depending on who is reporting for which outlet) & we specifically delayed our order (wifes haste) to get the octopump & the will it won't it (nope it won't) heated steering wheel in the first 2021 MIC dechromed.

NB wife, despite "cold" via neuropathy still insists its not really necessary due to octopumps ability to RAPIDLY pre-heat the car.

"heat scavenging" is apt a description. (fan setting 3 @ 20.5c is warm enough once defrosted, & obviously bum & lower back heated seat warmth is fast as heck also)

Will ask her to note temps as she stravels over coming weeks, ..she's now hit 12000+ miles since march 2021
