In car range indicator v actual

[Trotter]

How accurate should the range indicator be? Just two examples here, it is usually at least 10 to 20% out. On a 50 mile journey the range went down 59 miles. Several journeys over a week was 114 miles and the range went down 125 miles. In both cases nothing was switched on, no radio, lights, wipers, aircon, or fan. In the main the journeys were relatively on the flat, no serious hills. I’m sure the reading was more accurate when I bought the car new, 2 years ago.

I find on a long journey it's pretty accurate. For example last weekend I left home with 200 mile range, did about 150 miles and came home and had 50 mile range left. Radio & Aircon turned on, even used the demister a little bit!

My only concern was that I had charged to 100% but it was down to 98% before I moved off the drive, it was very hot but the Aircon had only been running a couple of minutes.

It's not very accurate at all.
After 4 years of ID3 and Born I mostly look at the battery percentage.

Same experience here., between 10 to 20% less in real life. Even when I go super smooth and with consumption of around 14kw/100km.

No matter the mode, always real range is considerably lower.

It's reasonably accurate in warm weather conditions but wildly optimistic when the temperature drops. I expected it to be adaptive (i.e. to respond to recent actual milage) but it doesn't seem to do so.

Can the tablet run excel? Might be able to throw in the battery percentage in and expected kwh/100 and get an accurate mileage, haha
