How To Optimally Charge Tesla Model S at Home and at Work: Efficient Charging While Away

Here is what Tesla Model S owners say about how to charge and how long to charge your Tesla at home and at work. The question is should you keep your Tesla Model S plugged in while away.

Several days ago one Tesla Model S owner asked in a Tesla forum on Facebook that he had asked if we need to keep the Tesla plugged in while away. Most people suggested yes. From the answers there were two ways to plug it in.

1. Charge it to 90%, and then plug it in and set the limit to 50% so that the battery decays to 50% and from there on it maintains.
2. Charge it to around 50% and let the battery maintain right around there all the time.

What are the differences between these two options and which is the better one?

"It's best to avoid charging beyond about 75% unless you are going to drive the car immediately," writes Nick. "I would set the charge limit to about 50% and leave it plugged in and perhaps raise the charge to about 80% from the app on my flight home."

Some Tesla Model S owners said they don't keep the battery even above 80 or below 20 for long time. Keep it between 50 and 60 as second option. Others suggest to charge to 60-70% and set limit to 50%.

Drive It As Soon As Charged
" Based upon what I've learned, use it as soon as possible after charging," recommends Abdullah. "Much like Quick Charging degrades the battery pack a negligible degree, so does letting the LEAF sit at 100% (which is actually 93%, but 100% on the gauge) cause some minimal degree of harm. So does charging above 80% most of the time. Taking it down to "90%" sounds good. Avoid charging if the level is above 80% also," he writes.

It seems that the general mode is to plug it in, leave your Tesla Plugged in and lower the charge limit to 50%.
