Just had a random thought the other day and was curious as to whether anyone (Tesla or aftermarket) have or are working on a portable emergency battery boost module for the Model S. I keep an empty gas can in the back of my ICE car for piece of mind though I have never had to use it. Would a supplemental battery module with, say, 10-15 miles of range make any sense? Kind of a quick charge battery booster that you could pull out of the trunk (or frunk) when you've somehow managed to pull a Broder* and run out of juice.
I'm guessing even a 15-mile booster would be pretty large (Maybe 5 kWH, assuming some transfer loss).
Thoughts?
