Cold weather Range Anxiety

Well after over 4 months of driving, I was feeling like I understood my Electric MINI E, it's been my regular car for all but 100 mile plus trips. Its been feeling like just a normal car, and I havent had much to report on this blog.
But my sense of normality has been shattered in the last week as Temperatures have plummeted, so has My MINI E's range. At first it seemed like a problem with the heater drawing too much energy, but it has become apparent that even with minimal or no usage of the heater, the MINI E's range has been severely reduced.
This weekend I drove the MINI E to my fiancee's as I've done many times, the ride there showed the first indication of a problem, I had to use the Heater a little bit but not too much it was 41 degrees out, and a bit cool in the cabin, but nothing too bad. I could tell I was using more charge then normal, but I never paniced and though I might not make it. The last 20 miles to her house are on a highway where 80 mph seems to to be the norm, I kept things at 65 mph and arrived at her house 78.2 miles, with 13% charge left and 11 miles to go. Thats a bit low, the first time I drove this I had 27% charge remaining, but it was within my comfort zone (just), as long as I didnt hit a detour, or miss her exit which would mean an extra 24 miles.
so on Monday morning I knew I needed to drive carefully, It was very cold it started at 35 dgrees outside and droped to 31 degrees during the course of my trip, the battery started at 48 degrees but was up to 71 by the end of the trip. At first I was afraid to use the heater, so for the first 20 miles of the trip I was freezing, I would hit the recircylate button every 5 minutes to keep from bringing in the really cold air, I kept the speed to 60 mph on the freeway, and stayed as far right as possible. After I got off the freeway the charge started to climb up and I felt I could afford a little heat before my fingers turned blue (I'd made a mistake and brought two left handed gloves, no rights) For the rest of the trip I'd bring the heater on for a little bit when I couldnt stand the cold, I had the air set to defogger to keep the fron window clear. I realized about half way that when I used recirculate the front window would fog up, but if I let the system bring in outside air it stayed clear, made for a hard choice, freezing or not being able to see. When I passed 50% at the 34 mile mark I knew it would be close.
When I got to 20% and had 20 miles to go I thought I could make it, especially as It seemed to hang at 20% a long time, but the last 10 miles to my house are on the freeway and up a very steep hill, I had to bring the car upto 60mph and was still passed by double trailer semi's going up hill. I reached the top of the hill with 3% charge left, after that it was all down hill and back roads about anouther mile to my house. I arrived with 13% charge and 11 miles to go.
I've driven the MINI E 5000 miles in 4 months but this may have been the last time I drive the MINI E to my Fiancee's house until Spring as it was just too close, and too cold. I was thinking if there had been freezing rain and I'd had to keep the defogger running at max heat to keep my window from freezing I wouldnt have even got half way, add to that the fear of being traped in the snow without heat and I dont think I'll be putting as many miles on #304 going forward.

NJ Leading the way to Solar Power

Move over California, New Jersey already has more Solar Powered Installations per mile and is growing. Here is a great article http://www.cnbc.com/id/33233060 about how State intensives are really pushing the growth of solar power in the garden state. I live in a condominium community where I cant install my own solar power but we are looking at houses and installing solar power will be a priority when we do move.

Heat

Well its starting to get cold in New Jersey so I turned on the heater in the MINI E. While driving with the Air conditioner on in the summer, barely used any electricity, I was shocked by just how much the batteries dropped when I turned on the heater. I've only run the heater for a couple days now, but the numbers are not looking good. During the summer a drive to work and back with no side trips and all on back roads a drive of 33.5 miles used 27% of the charge, but with the heater at half way and the fan on just slightly the same trip used 37% of the charge. Total range estimates are not that precise when based on these short trips, but my range has dropped from about 110 miles a charge to about 80, and this is on back roads never going faster then 45 mph. What will happen when I'm using the heater at max and driving on the highway? I'm worried about some of my longer trips, like to my fiancee's home, which is a 77 mile trip on mixed roads that uses 82% of my charge, I only have 18% to spare for heat on that trip. I'm also wondering whats the optimum temperature for the batteries, during the summer MINI recommended you use the AC to keep the batteries cool, which actually improved range, but with the heater drawing so much power I doubt it will be improving range unless its below freezing, I may be driving with my gloves on this winter.
Its still too early to say how significant heater usage is going to be, I'm going to need to collect more data ie drive with the heat at different levels. Got about 6 months to test the heater coming up.

Switching into Neutral

Well I finally had my first serious problem with the MINI E, the dreaded switching into Neutral problem, that other MINI E owners have reported. I was almost home after a 80 mile drive and came to a stop at a light on a steep hill. There was a VERY Big Truck behind me and when the light changed to green and I hit the gas nothing happened for a second then I started rolling backwards. I quickly hit the break and noticed the front panel had a big N on it while the stick selector was in D for drive. Realizing what was going on from other posts by MINI E owners that had already experienced this problem, I quickly shifted into part and hit the on/off button to turn off the car, all the while keeping my foot firmly on the brake and dreading the coming of horns blowing behind me. Once I was sure the car was off, I hit the on/off button again, the car booted up normally and I was able to shift into drive and get moving all before a single horn blew.
Not that bad of an experiance it could have been a lot worse, if I'd been unable to get the car started again, that would have been a very bad hill to be stuck on, no side pull off and a long long long way down to the bottom.

3000 miles

#304 had its 3000 mile service, was fairly uneventful. drove in and dropped off my car, I work nearby so I didnt need a loaner just a ride to work.
I mentioned that I've been noticing a bad smell in it I think it has something to do with all the air that gets pushed through the cabin while its charging. I also asked about the side decals we had been promised, but the service rep didnt seem to know anything about that, he wasnt the MINI E specialist (unfortunately I never got to meet him) but said he'd ask about it.
They finish the same day, no problems to report and the car was smelling much better, they even washed it ( hope they remembered not to wash the under carriage ).

Assignment 2 and an update

Well its been quite a while since my last post. I'd like to say I've been busy, but mostly I havent had much new to add. #304 has been humming along, driving me to work and back, and anywhere else I need to go. I'll be taking her in for her 3000 mile service soon, but really I've just been using her like a normal car.

MINI asked me to fill out assignment 2 on their MINI E website, it was mostly a 5 point scale of how much you agree or disagree with a statement, and covered charging, regenerative braking, low speed driving and safety, it also had a number of places for comments which I enjoyed filling out.

I'm getting noticed more and more, probably the "100 Electric" and "Just Say No to Gas" signs help. Have had a number of people stop me to ask about the car, and its great to show them just how much fun an electric car is to drive.

Ops and Ops again

On Tuesday I planned to drive to a remote work site to do some work on the computers there, its a long drive about 85-90 miles round trip all on highways. I made the trip once before in MINI E #304 and was looking forward to driving it on a long trip again. But when I went out to the Garage I found #304 unplugged and with only a 70% charge, Ops I'd forgotten to plug it in last night.

I figured I had an hour to spare so I plugged it in and waited, hoping that the 40A charger would be quick, but when I checked back it was only at 80% not nearly enough charge for the trip. So I took the Gas burner, my Z3 which I hadnt driven in a month. On the way I kept thinking the 40A charger should have charged the car more, an I wondered if I had the cars Amperage set correctly. Sure enough when I got back and checked it the car was set to 12A not 32A, Ops again.

It must have been set to 12A for a week and I never noticed, 12A at 240v is faster then at 110V but not as fast as at 32A. While forgetting to plug in the car is a problem I'm guessing all electric car owners will have now and then, I dont think setting the correct amperage on the car should be as tricky as it is with the MINI E. First I think the car could tell you the Amperage its drawing while charging on the display, as it is you just dont know unless you click through a bunch of menues maybe 10 or so short and long clicks on the selecter switch, a very clunky system. But more useful would be if the plug you connected the car to told the car what amperage to use, it seems to me a very simple thing to have a RFID chip in the plug that the car could read. While we are on the subject of the plugs, I dont like the current ones MINI chose to use for this project, they have tiny wires inside of them that look like they could easily brake from heavy use, and I cant see this as a good plug to use in a public place like a Mall as there is no locking mechanism, I can just imagine kids going down a line of EV's plugged in at a charging site and unplugging them all.
