How about using a front end cut from a Prius as a trailer? Keep the drive shafts etc, everything just as it is. Then, it is a pusher trailer plus charger with extra regen braking too. There would be a number of ways of doing this, if you want it simple, don't use MG2 Just MG1, and control the throttle position to control charging current? This will control torque at the same time, maybe even rig up a tow hitch control over throttle, like a trailer brake in reverse?

My instinct is that a real engineer with familiarity of the cars design would be needed to pull this off. David Roden makes some very interesting points. He points out that the emissions are high for less regulated motors. The pollutants that he sites are CO, NMHC + NOx. This certainly give me pause for moving forward. CO2 is definitely a motivator for me. The emissions for this are gallons (10% ethanol) typical x 19#CO2/gal (epa website http://www.eia.gov/tools/faqs/faq.cfm?id=307&t=11 ). I have evaluated the actual gas mileage using David’s metric of m/kwh x speed to determine kwh/h or kw of continuous power. I would need 14.3 kw generator. Using this 15 kw generator http://www.electricgeneratordepot.com/generac-5734-gp15000e-15-000-watt-electric-start-portable-generator-992cc-ohvi I end up with a mere 18.75 mpg not accounting for the reduced m/kwh for the trailer. Our Honda Element (2nd car) gets 25 mpg. The trailer would only make environmental sense if we can go back to using renewable energy while we are at the destination. My figures are pasted in from spreadsheet below. _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Read EVAngel's EV News at http://evdl.org/evln/ Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)
