Re: Battery warranty advice for 2014 Spark

Oh man that really sucks. You'd have to take a road trip to a state with freezing temperatures right now, find a hill, wait for the pack to freeze, and then regen down it to degrade the pack in time, while also booking an appointment to check capacity on the last day... Definitely not impossible but, you might be better off rejuvinating your pack's capacity considering it's doing so well. Replacement only really guarantees you get your Ah back to, what, 20% degradation minimum? You could probably do that to your original pack.MisturChips wrote: ↑Thu May 12, 2022 9:50 am
The 2014 has a 3.17 final drive and the 2015-16 has a 3.87 final drive, so that's the main difference.
I think they changed the drive ratios in order to compensate for 100 less lb-ft of torque. I Recall hearing the LG cells couldn't take the punishment. I DO enjoy the zippiness! With the lower final drive, does that mean the speed limiter is a lower value?
Bumped in to another 2014 at the charging station last night and checked his stats. with ;only' ~92Kmi on his, the pack was still at 45.2Ah. Mine is down to 39.1 with 97.5K, and I have 10 days to go....
Do you know where you heard that? I was having a discussion with Porsche a while back in viewtopic.php?p=28503 speculating about the max discharge power of a high voltage lithium pack using cylindrical cells as a reference, because I didn't actually have access to pouch cell discharge data. From my own knowledge reading the service manuals, I'm pretty sure the Busbar max current is not more than 400A, so it'd be really interesting to at least hear where things stand for INR voltage sag vs LFP in the spark and if it's a little different or very very different between a single string of high capacity pouches against several parallel strings of cylindrical cells.I think they changed the drive ratios in order to compensate for 100 less lb-ft of torque.
