Unrealistic autonomy driving me nuts

[HotHatchFan]

My life average is 20kw/100. Current since last charge is 18 (and has been the same since last 3 charges) with temp averaging 13-15 celcius. Avg in warm is 16 -where my warm is 25 celcius.

So maybe a bit on the high side, but still realistic?

Still, makes me go nuts that I get into the car and tells me 250 and I end having real range of 180. I understand calculation can vary but when the consumption is stable this such error is just too much.

Yes, a bit high, but not outrageous. I would just ignore the estimated range on the dash, it's what I do. For long trips I use ABRP (https://abetterrouteplanner.com) and/or the car's built in navigation to know more or less when I should charge in order to make it. The built in navigation is a bit more pessimistic than ABRP. There are cases where (from experience) I know I can make it home on the remaining charge, but it's still saying I need to charge. I think it doesn't want to let the battery go much below 20%, but when I'm on my way to somewhere I know has a charger, I don't mind arriving with 5%.

Don't think I have ever trusted the nonsense figures on the dashboard.
I was coming home from the Midlands once and the dash told me the whole way home I wasn't going to make it....

Pulled into the drive with 22%
You get the learn what it can do

I wish my case was on the positive side. But no.

I actually went into the task to have a log of real range and numbers don’t make sense. Average consumption at 17.8 kWh/100 should mean 325 km total range. But I actually get 174 from 90 to 25. Doing the numbers a full charge is giving 270km…

Edit: autonomy for range for the damn vocabulary police.

What do you mean by "autonomy"? The dictionary definition is:
1: the quality or state of being self-governing
especially : the right of self-government
The territory was granted autonomy.
2: self-directing freedom and especially moral independence

I guess I'm missing the point because of your use of the word "autonomy", which may be derived from media use of "autonomous vehicles" which could drive themselves, but doesn't seem to apply in this case.

For autonomy, read economy, and don't be a pedantic bore.

The OP is possibly a non-native English speaker. I live in Portugal, and in Portuguese the word for EV range is "autonomia", or in English, "autonomy". It's likely that other latin languages also use the same word. We also use "autonomy" for any type of battery powered device, eg: my iPhone has 10 hours of "autonomy". It actually makes sense as it refers to the independence of the car/device before needing to be charged or connected to a power source.

What!!
I asked a genuine question with a genuine request for clarification and you have to make a nasty and unnecessary accusation.
What is wrong with you?

OK, now that makes sense (I'm not a native Portuguese speaker )
Thank you for the sensible and courteous explanation.
Every day is a school day.

An ounce of common sense would have told you what they meant.
