Power consumption in winter

Deutsche Version
As a MINI E driver you realize that spring has arrived in Germany not only on the birds chirping and the green again nature. There are also the range of the car and the stability of the indicated range that make you feel happy.
Indicated range at a full charge is about 160km again and with for example SoC going down to 50% the estimated range behaves more predictible than during winter.
In winter usually indicated range at full charge was below 120km and with a SoC of about 50% even short trips of 20km became an intense experience.

Normally I try to use a public charging station at my place of work. But this charging station does not show the amount of energy the car took. Additionally I did not log the odometer every time I used my private wallbox. But there are a few charging operations, where I have written down the distance travelled and the amount of energy.



The Homepage of the MINI E reports an average power consumption of 14 to 17 kWh/100km.

With temperatures below 0°C in the winter, a cold battery with decreased power, activated cabin heater (to generate at least a tepid breeze) and switched on headlights you double the official value without difficulty.

Mostly you achieve values between 26 and 32 kWh/100km.

The final value of 22,5 kWh/100km is probably due to the significant increased ambient temperatures.

I'm curious to see what values I can achieve at ideal ambient temperatures during the last three month of the project...
