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...

MINI E in the snow

Deutsche Version

At the weekend I visited my parents again. After a 71km trip the charge level was reduced from 96% to about 25%, but I was pretty fast on the highway. During my stay I was able to recharge the MINI for about 6 hours at 12A/230V, which was sufficient to get the SoC to 86%.

On the way back I visited an aunt. I was very relieved that I had chance to plug in MINI E for another two or three hours. So a achieved a full charged battery before driving home on the highway. Due to adverse weather conditions i drove moderately and reached home after 70km with little more than 20% SoC and 30km left.

I've parked the MINI at the return in the open, because on Monday I was not working and the garage was already occupied by the second car of the household.

The next morning the car was completely snowed. The outside temperature was -7°C, were the battery temperature was still at 16°C. After the trip the temperature was at about 35°C.

The following re-charging costs me 20kWh electricity of 20.7 Eurocents/kWh. Extrapolated to 100 km this are about 5.80 €. At the current diesel price of 1.30 €/l this corresponds to a diesel consumption of 4.5 l/100km for financial tie.
