Handles seems no fun.
As for loosing some battery charge overnight - if possible, car should be plugged. It heats the battery after all and it is very good for overall battery health and longevity.

- rebuilder 8y agoIsn't the Tesla battery temperature-controlled? I.E. you'd use mains power to keep the battery at a safe temperature when plugged in, so it should be OK to charge? I don't know if this is what they do but AFAIK they do manage the battery temperature.
- MertsA 8y agoIt is. What's neat is that while other vehicles like the Chevy Bolt have an electric heating element to warm up the battery a Model S actually just uses the inverter for the motor to generate heat. It can essentially intentionally waste power without moving the motor at all. Since it's on the same coolant loop this warms up the battery pack.
- heyjudy 8y agoYou're so very wrong. You're suggesting how to potentially wear-out and overcharge li-ion battery tech, not improve it. https://batteryuniversity.com/index.php/learn/article/how_to_prolong_lithium_based_batteries https://batteryuniversity.com/index.php/learn/article/how_to...
- davidgould 8y agoTeslas by default do not charge to 100% unless you set "trip mode", so it is fine to plug in and charge anytime. Also, the car will use shore power for heat and battery conditioning even if it does not need more charge.
- MertsA 8y agoHe's spot on. Tesla vehicles heat up a cold battery pack when charging and IIRC Tesla suggests an upper charge limit of 80% for daily driving to minimize any additional wear from keeping it at a high state of charge all the time. The best approach is to plug it in and have it only charge to 80% and leave thermal management to the car, it will heat up the pack if it needs it instead of just charging it cold.
