Average miles/kWh over a full year - Less than I expected

[Teslaeata]

I use the preconditioning but whilst car’s plugged in and only when I’m going out on a day trip which is quite often.

I’m sure you’re correct, for short journeys probably a waste of kWh’s.

Battery will look after itself insofar as preventing harm from extreme heat or cold.

I just looked at the window sticker. Says 91 MPGe - 97 city and 84 highway. I'm guessing that MPGe number is from the pack, and not the wall.

My buddy drives a Tesla, and he had told me his charging loss is around 10%. So I would think we are all that or more.

My daily driving scenario is pretty ideal for EV efficiency - other than that I live in Minnesota. I'm guessing all the preconditioning drags me down a fair bit as well.

Interesting…..the window sticker for my 2024 Premium AWD ext-range says 99, just about a 10% improvement over 91. I know the 2024s got (a) different motor(s) from the 150-Lightning…..could that be the difference?

This is why I only precondition if I truly need a warm battery to provide extra range for a long drive. I’m rarely driving over 50 miles a day. So I rarely need to precondition. With short drives, preconditioning seems to be throwing money away. There is the argument that preconditioning may extend the life of the battery, but the cars haven’t been around long enough to have a cost/benefit analysis on that.

I’ve been thinking about this, too. I have a very short commute….rarely over 10 miles in a normal weekday. I’m trying to figure out battery life in the winter vs. wasted kWh.

The first winter I had my MME I went back and forth on if I should set departure times or not, as I generally never have to think about range.

I remember doing the math, and I came up with each precondition session would cost me a bit less than $1. So not more that $5 per week for my 5-6 departure times.

I decided that I was going to do it, just because the car is more comfortable after preconditioning compared to a 10-15 minute cabin warming. It stays warmer in the cabin for a longer period of time, and it is just generally more fun to drive. There is definitely an increase in available power with a warm battery. And if it provides some small level of long-term battery health, all the better. I figured $5 a week for 4 months a year was worth the added comfort and enjoyment.
