Can I use my electric vehicle as power source and backup generator?

Some vehicles may be used as power source and backup generator. For example Ford makes a truck called the F150 Powerboost.  It is a hybrid truck that uses a 3.5L V6 coupled with electric motors and a hybrid battery.  It is capable of generating up to 7200W at 240 Volts and can be connected to someone’s house using a manual transfer switch. It has been around for several years and seems to be well liked.  You can get more information about it on the Ford website.
