Except that half the time I can't find a parking space and am left circling or running a few errands. How much charge could a person expect out of a 1/2 hr appointment if one was lucky enough to park at an unoccupied charging station? Having been stuck on the wrong side of accidents etc for up to 8hrs at a time, trying to stay warm with enough battery to get home scares the crap out of me.For the system to work the medical appointment location will also have charging facilities. So now you are looking at a two hour drive in one direction.
The fear of Lithium systems is because they don't work well below zero. It's handled by heating the batteries. But not well addressed, IMHO, is what to do with a car that had fully charged batteries but now the temperature is at -40C.
You normally cannot take significant current out of a battery until it's above -20C and even there it's only a small amount. The way we did it below -20C is start a generator or apply external power to heat the pack up to -20C so that then the system could run. The heaters continued on up until 0C at which point then the batteries were allowed to be charged.
Probably, mostly, my biggest fear is change, I don't like change much......
