My father (Dangerous_Dan here) and I have done our own research on a switching power supply that powers my 2009 Honda Accord which runs without an alternator (another subject please).
We discovered that a PROPERLY TUNED battery charger will not pull the maximum wattage from the 120VAC source, instead the drain is proportional to both the
temperature of the battery and
the remaining capacity.
If you put two Honda generators on your EV while driving and monitored their RPMs (yes, they have ECU monitors for that), you will see they increase in load as you drive. The result would be that the generators can sit at low RPM's and conserve your ethanol until the batteries become severely drained.
