I topped my car up last night for a long journey today. At 95% last night it was predicting a range of 185 miles. This morning at 100% the predicted range is 189 miles. It is cold (5°C) this morning but this range seems excessively depressed. My XPower is one year old and I don’t remember it altering the predicted range in cold weather last year - but that might be my memory.
Am I looking at battery degradation after only 1 year or is it just cautious cold weather prediction?
 
My X Power at 100% charge in Summer showed 256 miles. I charged last night to 100% this morning it showed 189 miles,
and I expect it to be worse than that, if we get a really cold snap. My X Power is 15 months old and done, 10,735 miles
You will get less range in winter, simple's.
And the colder it is, the less you get. Doesn't bother me, that's just the way it is. 🙂👍
 
Yep! sounds about right, converting it to km/kwh its around 5 , for a lower spec one ( mine ) I am currently on 5.5 , a tad warmer and also with less weight and less reciprocal/frictional losses of the extra motor. There also might be a degradation loss of up to 5% in the first year , finding an exact figure is akin to proving the existence of dark matter.
 
These are my last year of charging stats giving what the efficiency would have to be for the car to reach the GOM estimated miles. Start is when the car was plugged in to the charger and end when the charger was unplugged. So even by standing still the GOM will change it's mind, I am assuming based on ambient temp and any battery balancing it has done during the charging session

My Xpower is a year old too, yesterday morning at 100% it estimated 224 miles Southern england 5 deg C, i did an 80 mile round trip vast majority motorway and arrived home with 59%, vibe zone speeds.
Consumption showed 3 miles per kWh.

About normal then , 61.7 kWh usable so 185 miles real range
 
I was surprised that the GOM estimate changed so much on my Trophy (LR) from 186mls to 215mls at 88% SOC when I reset the accumulated total on the trip computer at the end of December. This was a months worth of motoring covering 793 miles and a time of 32:38. I'd seen a small difference before of around 10 miles, but this much larger one effectively changed the range by 10% based on the official range of 270 miles. Whether the change was a result of the charging regime over the past month, ie only short charges from an already relatively high SOC, or other factors I'm not sure.
 
I Charged mine Mine (Trophy LR) to 80%. The temperature was -3 degrees or greater. The display said 170 mls for 80%. Having used the heater function twice from the app to defrost the car the SOC this dropped back to 79% and 168 mls.
As a side note, in the old days with halogen headlights the heat would have been enough to defrost the headlights, a drawback of LED's with very little heat, meant manual defrosting of the headlights.
 
My repeated long trip is Lismore NSW to Ipswich Qld, Have done it a few times in the XPower and many more in my old car. Most of the trip is on Dual Carriageway and speed limit is either 100kph or 110kph.
In my ICE car (Stated Highway fuel consumption was 4.7L/100km) I would get;
5.2 L/100km at the speed limits;
4.1 - 3.6 L/100km if I cruised at 85kph (depends on winds, temp and traffic) but well under the published figure.

In the XPower I have only had a few runs on this trip.
First two trips I got a bit under 12kWh/100km at about 85kph.
Next return trip was in wet weather and traffic and added about 1kWh/100km
Last Sunday I did the same trip but was in a bit of a hurry, so drove at the speed limits. This returned 17.2kWh/100km.
So it seems the lower speed saves about 4 or 5 kWh/100km. Roughly a difference of AU$14 and an increase of duration of about 40 mins.
 
I could charge at home, but that would use all the solar power for the house. Being a 10+ year old system it does not have enough capacity to supply both.

Currently looking at upgrading the home system and then would have the surplus power to charge the car. While there is no such thing as free power, it would be cheaper and I can kid mydelf it is "free".
