First off, I’m a relatively new Model 3 owner and brand new to the forum, so I apologize if this specific subject has been addressed. I know that it is recommended to leave the car plugged in whenever possible. However, I do notice that the charging starts and stops quite a bit, as referenced by my notifications from the Tesla app. I was away for the last three days, and left the car unplugged. I lost about 20 miles of range during that time. My question is how much electricity is used to keep the car plugged in and charging in little spurts? I feel like it could be quite a bit more than just charging the 20 miles back up, which only takes one hour. Has there been any research done on this? Or, can it just be assumed that charging a few miles at a time (after short stints of vampire drain) uses equivalent electricity to charging 20 miles all at once?
