As a new Tesla driver, I'm hoping someone can help me understand energy usage over 900 wh (off the graph actually). I just happened to look at the energy graph and noticed the last few miles showed very high usage. All I was doing is driving slowly around a parking lot and practicing backing up with the cameras. I drove around my neighborhood and it slowly came back down. Anyway, I will include some pictures and any feedback is appreciated.

Question on extremely high energy usage
- Thread starter AbbyNormal
- Start date
That's *really* high. I can achieve consumption that high while driving like a maniac, flooring it, uphill, both ways in the Winter with no shoes on. Just lurking around a parking lot shouldn't look like that.
Well, considering the car shows the temp is 104°F, I imagine that you were driving around so slowly that climate control accounted for a significant amount of your consumption.
The longer it takes you to drive a mile, the more energy the climate control is going to use over the course of that mile, and the higher your Wh/mi will be.

If it’s been off the charger for awhile it’s not uncommon to see very high wh/mi during the first few miles especially if you have AC or heat on. Winter months are the worst since the car aggressively heats the motors so you get consistent regen even in cold weather.
Good grief did you have an elephant in the trunk?
Joking aside, as others have noted, your A/C was probably working hard, and at such slow speeds (when it takes a LONG time to drive 1 mile) your energy use *per mile* will be crazy high. Put another way, technically when you are stopped, your energy use per mile is infinite even if all you have on are the interior lights (though of course the car is smart enough not to show it this way).

You can’t base energy consumption on a short trip like a drive through a parking lot. Short trips, especially ones that involve a warm-up of the cabin from cold, or a cool-down of the cabin from hot, will have a large amount of energy going to the HVAC.
Take a 50 mile drive and get back to us.
Thank you for your response, this been happening for the past 1-2 months. I drive the car everyday to work and on average about 65miles per day just to go to and back from work. The scary thing is that I tried turning the AC to about 4/5 speed, it was a hot day so the temp is on Low, and I drove on the freeway about 50mph, and the energy consumption passed 900wh/mi and you cant see how high that number is because 900 is the cut off. See image attached. I hope someone can help me solve this issue.
Thanks

As someone mentioned above, if you are doing very low speed driving (e.g. a traffic jam) with the climate control running at full blast, the energy consumption of the climate control will be the big factor. Does this high energy consumption happen if you turn off all climate control (AC off, temperature set to the lowest possible to prevent heater use)?
Since it has only been happening for the past 1-2 months, how has the weather been recently compared to before?

Start with "stop looking at the 5 mile range". I am virtually certain that your 65 mile per day work and back commute does not show 900 wh/mi. If so, please show is a trip meter that shows that.
Otherwise, this falls into the "why is my car not getting rated range" which is a discussion for the thread here:

i bought my model 3 in aug 2018. After the software upgrade I only got 316 miles when charged to 100%. Last night I got only 312 miles from 5% SOC to 100%. A 4% degradation within 10 months? Have others degraded similarly?

The car says it’s 110°F outside and you have the air conditioning set to LO, which is maximum cold.
What exactly are you expecting?

I recently did my first AutoX, and found I used as much energy cooling the car (and myself) between heats as I did for the actual runs. In about 35 total minutes of AC use I used about 7% battery, and three 0.6mi runs, I used about 7%. So, that was total about 11,000Wh in about 2 miles
