Oh great ice, that means another winter weather post…yup.
This is what the Bolt looked like when I woke up. In the midst of an ice storm here in Southeastern Michigan (this is after a deep freeze last week and springtime temps in the 50F’s over the weekend truly a dizzying winter). The temperature swings have allowed me to experiment a little with the Bolt.
Experiment #1: How well does the preconditioning work when the car is encased in ice (the ice appears to be a little less than 1/4″ thick and is very granular in nature–not really a continuous sheet).
Well here it is after one precondition (10-15 minutes):
Not bad, the front windshield has a large clear area as does the passenger window. Lets try another precondition:
Look at that! The entire front windshield is clear as is the passenger window (and rear passenger window also has some clearing). As well is some of the front hood. (Temps are hovering around freezing.)
This is after about 1/2 hour of total preconditioning (it runs about 15 minutes per start).
I had also documented a similar experience with the Focus Electric (FFE) (however I can’t seem to find those photos). That experiment was with about 1″ of fresh snow on it and after 30 minutes the results were similar to the Bolt’s above.
Experiment #2: How sensitive is the Bolt’s Guess-O-Meter (GOM)?
The FFE’s GOM was really sensitive: If you drove on the highway you could see the range to empty fall really quickly, then once you exited if you drove slowly for any length of time you could see the range increase dramatically.
On the Bolt the trip meter will display your average consumption since last reset in miles/kWh. In the summer I can get 4+ miles/kWh (which yields around 250 miles on a charge). During the deep freeze using heat, etc. It was reading around 2 miles/kWh (and thus the GOM was showing 120 miles or so).
The experiment: How fast does the GOM react if I get that miles/kWh value back to 4. For the warmer days I was able to drive around with the HVAC off and get as high as 4.5 miles/kWh (now that its closer to freezing it has fallen back to ~4 except for when I have to run the HVAC to clear the windows).
What did the GOM do? Its still reading around 124 miles of range on a full charge even though I’ve been stretching it. Thus it is far less sensitive than the FFE’s GOM (by now the FFE would be reading its max range). It does give the car a less “flaky” feel to it even though in rapidly changing conditions like this it may be less accurate.
