Hi Mark and All,

                There is no reason a RE trailer is needed, just use a trailer 
hitch mount can hold up to a 250lb generator.

                   One thing not mentioned is the generator.  A single phase AC 
is very likely to burn up from PF/peak amps reasons.   You need either a 3ph AC 
or a DC generator.

                   I prefer making my own using go cart racing engines which 
are low cost, lightweight, easy to find hotrod parts and have stock carbs that 
run on ethanol, methanol, propane or NG.  By hotrodding them you get more 
power/lb and can make them lower emissions.  The common 6hp, 200cc  one can 
easily do 10-12hp .  It with it's alt only weighs 45lbs giving 9kw or so when 
done..

                    I'm experimenting with building my own 3ph alternator from 
E tek magnet rings and making my own stator coils.   The magnet ring discs are 
on the shaft and the stator is bolted to the engine block making it very 
lightweight.  These are call 'axial flux alternators' with lots of vids, etc on 
the web though mostly for wind generator which I'm also doing as dead easy to 
make..   

                     Another is find a 3ph small generator and modify it.

                     Now with the DC charging ports on production EV's this 
might be a business for someone. Since few will ever need them but eases their 
EV range fears and allows the EV for the only car deleting the need for a 
second gasoline car in many cases and broadening  the EV market many x's to 
people who wouldn't consider one.

Yes, that's a kid's sandbox on wheels!  The shape reportedly did wonders for
the trailer's aerodynamics.  It also drew smiles from the TdS officials and
spectators.

A battery trailer allows you to have a small, light battery for your EV's
daily mission, with easily-added optional longer range when you need it.  
The obvious tradeoff is the awkward maneuvering you get with a trailer.
