Another novel use for the FFE

Found another novel use for the FFE:
Another novel use

What am I doing here? It would appear that I’m charging the FFE off of a covered RV. The novel use here is to provide a load for the generator in the RV. While in extended storage (say over winter) the engines have to be run about once a month or so. For the generator the Onan people told me that when you do run it you have to provide a load. I don’t think I could provide a better load to the generator than having the FFE charge with its Level 1 EVSE (which will draw about 12 amps).

Other options for drawing a load would be the A/C (which shouldn’t be run in cold weather), or a ceramic heater (which would have the benefit of heating the interior of the RV). In both of those cases, though, the electricity produced will simply vanish into the air. With the FFE the electricity goes to good use charging the battery (granted only using Level 1 for about 20 minutes I’ll be lucky enough to get a mile…maybe).




Extending your range?

I’ve seen a few people post ideas in the FFE forums about how to pull a generator behind your EV to give you that extra bit of range. It is an interesting thought…enough of one that someone actually designed a thing: I give you the EP Tender (here is their main website).
EP Tender
I don’t think this guy will work for my beloved Focus Electric because he taps into the vehicle between the charger and the battery (since most EVs don’t allow charging while driving). It basically turns your EV into a PHEV with a cute little trailer. Even more fascinating is the simple solution to backing up (watch the video).
