Mobile charging is a possibility:

> Most gas-powered generators that your roadside assistance will come with provide 9.6 kilowatts and generate 240 volts. Inquire with your roadside assistance provider to know whether they offer a mobile charge. Often that not, they may be offering it.

Ya, they are coming with basically with a diesel generator that outputs 240 volts...which should give you 20 or so miles in 30 minutes?

Or towing (on a flatbed) to the nearest charger is an option if you can't bring power to the car.

Heck of a lot more involved (and expensive) then getting a jerry can filled.
