When fully charged how many miles reads on dash?
 
I tried slow charging and fast charging and it seems to vary slightly no matter how it's charged. What does everyone's mile range say when charged for a full 12hrs read?
I know outside temp plays a small role.
Just trying to find average real time range once unplugged from being fully charged.

I find temperature plays a BIG role!
The best I've seen was 80 miles at 20C. Worst 40 miles at -20C. When it's cold out, the estimated range also drops a lot when I turn the fan on. (discussed elsewhere here).

When fully charged, the dash will show range based on the calculated m/kWH (or km/kWH) measured by your last trip and current capacity of the battery.

In my case, at present, with temps in the 20's, I'm seeing 2.7 m/kWH (with heat usage) and around 54 miles range estimated on a full charge (BMS seems to estimate that my pack currently has about 20kWH available when fully charged).

Best I've seen is 77 mi @ full charge (warm air temp)
Worst I've seen is 54 mi @ full charge (cold air temp)

My Average mi / kWh is 3.8

Thank u guys.
My best was 72miles full charge and my worst was 48miles.

My best was 72 miles also. I started off with 59 miles.... Worst I've gotten was 58 miles.

Highest i've started out with was 72.


Lowest i've started out with was 50.

Highest was 169km's. (105 miles) I never got that again however. You'd think I'd be making this stuff up but I can assure you tis no lie! Lowest I believe was 84 km's. (52 miles.)

If you navigate to the "RESET" menu, and reset it, the average m/kWh gets initialized to 3.9m/kWh and when you then navigate back to the main menu, with a full charge it will show the theoretical range that you would get from the battery pack if you averaged 3.9m/kWh.

I believe, at this state, you can estimate the full capacity of the battery by dividing the range indicated by 3.9. In my case, I reset it every 1000 miles, and have seen numbers as high as 111 miles range, which equates to 102 / 3.9 = 26.2 kWh, instead of the advertised spec for the pack of 17.6 kWh.

For me, it always goes down from there, as I'm not able to drive slow enough to maintain anything close to 3.9m/kWh.

After that initialize reset, the number that is shown in the morning, after a full charge is based on the average m/kWh achieved the evening before on the "start" menu. i.e. it estimates what I will get today, based what I got yesterday afternoon on my drive home from work.

At 80% charge rate, I show 230 miles. Oh wait, that's my Tesla parked next to my smart. It will blow the doors off a Corvette, my smart won't.
But each has its place and each is fun in its own way...
