Batteries:
What I have learned over the years about batteries is that, in order to get the longest cycle life from your battery, you should avoid discharging below 50%. Tesla recommends that you not charge to greater than 90% state-of-charge.
Tesla’s charging app implies (recommends) that, on a daily basis, you should charge between 50% to 90% state-of-charge. You should avoid discharging below 40% state-of-charge. Of course, the car is designed to occasionally be discharged over a larger range for longer trips.
I recently took a Photo-voltaic/battery design course and the recommendation was: size your batteries for the design load and then take the number of batteries and multiple by 2 so that you don’t discharge below 50% state-of-charge to preserve the battery cycle life.
Apple recently had a problem with the iPhone Li-ion batteries. They recommend that, if you are not planning on using your iPhone for an extended period of time, you should leave the battery at 50% state-of-charge. This gives you 10% margin to the lower limit of 40%. All batteries self-discharge. When the Tesla is off, the electronics in the car draw a small amount of current adding to the parasitic discharge.
I make an effort to avoid discharging below 50% state-of-charge and have my recharge set to 90%. Shorter stops at the superchargers.
