Mobile Battery

Is there or can the Tesla team create a mobile battery for the Tesla, like gas vehicles have gas cans for times they get in a rough situation to get mobile fuel, it would be amazing to have a mobile rolling suitcase type battery pack (that may even plug into a 110 power source) that could be easily removed from the vehicle for convenience as well as safety? Even if it can only add 20+ miles to the vehicle. I don't currently own a Tesla, so this may not even be a problem but I'm super excited about the idea that is going around about the $25k car the team is wanting to build. This was just one concern of mine living in a rural southern state that tends to be behind on technology as well as other things is the ability to properly charge the vehicle and use the car effectively.
