How do you display energy?

A quick poll

Both. Wife whose car it is prefers miles. When she lets me drive it, , I prefer percentage...

I like to keep track of how much my battery’s degraded, according to the BMS. Started with 316 miles, and down to 304 by the second month

 

[JWardell]

If you value your sanity you will set it to percent and never stress over range and battery degradation!

 

[captanzuelo]

I just pull up the Energy tab and it shows me the current battery percentage while im navigating to my next destination. I do wish it would show the percentage even when not navigating

 

[Kabillyhop]

Why do we have to choose? There is plenty of real estate in that part of the display to show both miles and % of battery remainng.

Mine shows in Km

Percentage while charging and miles while driving.

 

[Lounanne]

Percentage. After one day of driving, and looking at the energy chart, as @JWardell indicated, I would be too anxious seeing the range in miles.

Is that normal? That seems like a big drop in 8 weeks..

On a side note, do you folks plug in every night regardless of % or do you only plug in when your batt gets to a certain % like say 50%?

I plan to keep mine on percent when I get mine (hopefully this upcoming week).

I’m trying to figure out best way to calculate remaining miles when showing percent...do you calculate remaining distance by looking at your average wh/mile consumption for current trip and do the math based on remaining battery %?

Plug in daily - charge to 65% and go higher when I need it.

I plug in whenever I am parked at the house. Set for 90. I tried charging only when i got home at about 40% but got caught short one day when I got called out on an emergency call. So I always have a full tank by 0400.

I just multiply the percentage with 2.5 when doing local trips, longer distances freeway times 2 to keep on the safe side (probably 2.2-2.4 would be closer). Anyway the built-in trip planner is good in estimating when you need to hit the next supercharger in that case.

Last 500 miles averaging 300 Wh/m (without any long/freeway road trips)

I don't have anything to compare, to make the call if its normal. Doesn't bother me much anyways, as average Wh/mi really dictates the range. On a good day, I'll be getting 240 Wh/mi which translates to an acceptable 302 miles of range.

Yes, I first look at the average Wh/mi over the last 30 miles on the Energy page. Then I look at the current battery state of charge. Convert that into kWh(based on a 72.5 kWh useable battery) and you can divide that number by your average Wh/mi.

Example: Given, 250 Wh/mi average at 50% Battery.
Thats 36.25 kWh of battery divided by 250 equals 145 miles of range left.

Completely agree

That’s what I thought, thanks.

Why use 72.5kwh? I’ve read that even though it’s a 75kwh battery, one should use 74kwh for total capacity.

I honestly don't know how many kWh Elon has let us tap into for consumption on our Y's. But I know my 302 mile range(currently) at 100% is based on 240wh/mi, so I multiplied the two and extrapolated 72,500kWh of battery juice.

I had a loaner MX and I have to say if you put an X-sized screen in the Y and let me see my energy use on an always-visible X-style dial, I would have a perfect car.
