2023 Mini SE Charging Guidance

Different countries, different laws. Manuals are heavily influenced by lawyers and marketing. They are definitely not an engineer telling you what is actually best for the battery.

In this case, I'd guess New Zealand has some consumer friendly liability law that meant it wasn't worth the risk to provide specific guidance.

 

The car is learning. Last full charge was displayed 183km when unplugged

 

I have no idea where you are, but much of the US is well below freezing so you will have less than 110 miles of range if you're in those conditions. Type of tire, driving habits and speeds all play into the GOM range (Guess-O-Meter) and Mini's GOM tends to be a bit pessimistic.

 

As @Puppethead proved, you can turn off your heat for increased range.

 

I, like many experienced SE drivers, mostly ignore the GOM (focusing on battery % instead), but I do notice after charging it starts out with fewer miles than the EPA's 110-mile number in cold weather. The SE knows how cold it is and perhaps it assumes I'm going to use the range-robbing heater.

 

The GOM takes into account the temperature where the car is located as well as recent performance. You can test this if you don’t drive by watching the estimated range change as the temperature changes.

 

Don't even worry. I get 43 miles at 99% charge! Well I was running cabin comforts..it was 100% just a minute earlier.

 

Doing better I see, Teslarati.

The GOM is a waste of space in most of our opinions, it's that bad. I'd rather have a % readout.

Rain will hurt your range. Cold temperatures will also hurt your range. Higher rolling resistance tyres will hurt your range.
You can't change the weather, but you can be picky about tyres. Unfortunately, many of the US winter tyres options don't have rolling resistance info available. Some of them are also available in Europe, where 'tyre labels' are required for new tyres. These give basic Rolling resistance, wet grip and noise information. The Nokian Hakka R5, popular with our Canuckian members, scores a 'B' for rolling resistance. This is excellent for a winter tyre. The standard summer tyres are all 'A's. My Nokian WR-G4 all weather tyres are a US market only tyre, so no rating.
Walmart cheapos tyres tend to be 'E's...

My personal experience:
I found my summer range in 70-90 temps to be well over 110 miles without much effort. I did one run, at mostly 65-70, at 146mile calculated range.
In winter, down around freezing, I am usually looking at around 100, less in wind and rain.
