In for service and first contact

Deutsche Version
Today in the morning I drove to the Munich MINI service center to get a scheduled change from winter tires to summer tires. As I handed the car over to the service personnel it became clear, that MINI E #014 needed not just new tires, but a complete service.
Since December 2010 #014 tried to tell me that service was needed. I always interpreted it as a test symbol during the starting procedure. So I was very embarrassed as I was told that the car needs service immediately. I leaved the MINI service center without #014 and got to work by public transportation (which was not a problem because I still have an annual ticket for the public transportation, work was just a few subway stations away and, anyway, it was too late in the morning to get a parking space at work without trouble).

In the afternoon I got a call that the service no problems emerged and #014 is ready to come back to duty. Thank you, MINI Munich, for the fast "unscheduled" service and the fully charged battery!

My first impression on the new tires was a smoother driving and less noise. Furthermore I was enjoying the new wiper blades in the upcoming rain.

On my way back home I had first contact to another species of EV. Of course I've seen many Toyota Prii, perhaps some Honda Insigths and once or twice another MINI E in the traffic. But I didn't meet any other battery electric vehicle (not even a Tesla Roadster) nor an electric vehicle with a range extender (like the announced A1 e-tron) on Munichs streets. But today I gave way to a Smart ED and followed for a few kilometers before we parted ways.

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...
