How do you mange to never let your car sit at 100%? I'm just curious, seems like it would be a lot of work and take an awful lot of planning to pull this off every day.
Actually, using the charging timer, this is very easy, just time it to be done charging when you are ready to go. But really my understanding of it is if the battery sits at 100% for more than about 8 hours is what is bad and for me, we don't have a charger at home, so it never sits at 100%, as I have to drive it home after charging, although that is only a couple of blocks.
"more than 8 hours" statements need to be clarified. It only takes a second for heat and High SOC to start playing the bad guy.
So we balance need with BMS and charge management. Problem with all that is it will take 2 years (since one year is not enough to convince anyone of anything) to really provide decent anecdotal evidence.
The big ask; Is it better to charge to 100% during the coolest part of the day (night) even if its not all that cool and then drive it to under 80% first thing in the morning or is it better to fast charge in the middle of the day getting the batteries hotter but driving down that high SOC right away.
Realize the slower charge option means high SOC both coming and going and in the L2 situation, it could be as much as 2 hours because of the speed of the charge. Now you can drive enough to lower the SOC to a less dangerous range in 20-30 mins easy enough.
Wnat would be nice is a comprehensive profile of what an active TMS actually does, when it does what and to what degree it does it. Problem we have is Nissan is only pack that good monitoring programs and yes, the monitoring program is only as good as the instrumentation feeding it and we all know that Nissan instrumentation isn't that good. Of course it wasn't meant for public consumption so it leaves a lot to be desired but at least its something.
Everything else seems to be more user inputted opinions based on something
