I know this has been asked but I still haven't seen an answer to this situation:
Most of the week I use 10-15% per day battery capacity. On weekend though I charge fully and often stop at a supercharger to add charge and arrive home with about 20% SOC. I've read here that a plugged in battery is a happy battery and I've also read that discharging to 30% and recharging to 80% is the sweet spot for the battery.
So, should I charge nightly which would charge the battery from say 65 to 80%, leave the car unplugged until it drops down to 30- 50% before I charge or just leave it plugged in each night but don't charge until I get to the 30-50% range? Is plugging the car in helping with anything other than charging? (keeping the battery warm, etc.)
