Ok, I did this as a test and can't envision any situation where I would use it myself, but maybe it could be a service (albeit a slow one...) for stranded EVs.
As a background, during power outages, I use my Prius in conjunction with a 5kW UPS to power my house. I had recently upgraded the UPS from a large cumbersome one to a more compact one. Normally, the battery feed from the Prius is run from the car through my garage to the UPS in the basement, next to the load panel. The UPS is now small enough to sit in the back of the Prius, so I wondered how well it would function in powering my EV charger. Pictures of the test are below:
So basically, with the 5kW UPS putting out 230v, I was able to get about 10 miles per hour of charge when the current was set for 15A. At 15A, the UPS load LEDs were showing about 100% so I didn't go beyond that. 10 miles per hour charge rate is less than a L2 charger, but hey, this charger can come to you!
The duty cycle of the Prius engine when the current was set for 12A was 55% on, 45% off. That's about right since the Prius is capable of putting out about 6kW.
