If EVs are designed to be capable of running off of an external battery safely, a service could drop off the battery to the stranded driver, charge the credit card for the service, put a hold on the card for the value of the battery and release when it is returned. you could ask for one or multiple packs depending on how far you are from the next charger. They could pick it up for an additional fee. Of course this should be a national service because you are likely to experience issues on longer travel.Keep in mind that a 100% efficient generator producing 250 kW (the maximum size of a Tesla SC) would require 335 HP of prime mover energy or 33 Powerwalls. Tesla has mounted powerwall superchargers on trailers for use during the black outs last summer in California but don't get the idea that Ray's Sunoco is going to be able to put something like this together.
There have also been some reports of smaller enterprises mounting a more reasonable sized generator on/in a truck and dispatching that to stranded drivers. The charging rates are, of course, pretty low but the idea is that in an hour's charging you might pick up enough to get you to a supercharger. The problem is that because of the slow rates achievable with a reasonably sized mobile solution ties up the truck for an hour or more per customer so that perhaps only a half dozen customers can be served per truck per day. I don't think they caught on.
