Because you can basically run a seat heater and the heated windshield and everything gets warm (fan speed on 1) except the foot box, which is freezing. So If someone can figure out how to heat the foot area it would be great. Here is the bigger issue. The car has a battery heating/cooling system that cannot be adjusted. So in cold weather you are burning thousands of watts to keep that battery cozy. I think the issue of winter range is related to the inefficiency of that system. That's what a lot of the plumbing under the front hood is for. I would be really crazy about the car if it had 50-100% more battery.. and DCFC.. and a sunroof.
When I mentioned bitter cold...I meant it. We're talking about -20C. The heater solves two problems, one being able to heat the cabin quickly and efficiently, the other heating the battery preserving range instead of siphoning power from the battery to heat anything. Of course, I'd have to do more research because the last thing I'd want to do is cook the battery. A guy in Wisconsin installed a heater in his i-MiEV with great results. I helped a friend install one in his Jetta TDI, it truly is the "must have" accessory for northern climates. I'm hoping this is possible with a B250e but the last thing I'd want to do is cook the battery. No doubt I'd run into warranty issues.
DCFC and chademo aren't important to me as we don't have quick charging within 1000 miles of where I live. I do have 9.2 kW of solar, and a 7.7kW EVSE installed at home.
