I am not sure what a wheelhub powered trailer is? Are you talking about a pusher trailer?

"On the other hand 7kw would be much better at extending the range, 60 amps after power conversion losses could sustain speeds of 40mph as long as you have fuel and double the range of the pack at 65mph!"

I wouldn't be losing speed with the generator trailer, I was just commenting that at around 40 mph the generator could maintain that speed without the assistance of the battery pack. When I go faster it will use the 60amps from the generator and the rest from the batteries so speed will not be limited.

im not sure what a pusher trailer is. im just suggesting using wheel hub motors on the trailer. that way the motor in the car doesnt carry all the load.

Are suggesting using electric hub motors on the trailer powered by something to push the car and reduce the load on the Main motor in the car?? Need more details or a better description to understand how this would be effective.

On another note: My project has slowed this week while waiting for some parts and the cold weather has reduced how long I stay in the garage. So instead I am working some overtime to free up some money for the next shopping spree.

yes i was.. well im assuming you can find wheel hub motors that would be able to operate at the same RPM/SPEED as you need to be usefull. might just be my hair brained off the wall thinking.

Im with you Kelmark, I am not a fan of the trailer concept...I would much rather go with a removable spot inside the car where you could "install on demand".. I am planning the same sort of setup...

7.5kw should be enough to power a lighter weight good aero car continuously at 50mph...You can find gensets for 900$ that are about 230lbs for 10kw peak 7.5kw cont.

If I have to take it in and out of the car I need to keep it under a hundred pounds so it can be lifted by just me. I found AVERO™ FLEX-LITE (FL) 2.5 kW AC/DC Diesel Powered Generator Set which is under 100lbs.

Another one I am very interested in is 5KW and weighs 165lbs;

Does anyone else know of any light weight diesel generator with auto start?

very true, if say you had no help to install it or remove it, 230lbs would be too much...Maybe two lighter gensets instead...

The problem w/ most gensets is that they're relatively heavy in order to lower costs. It's better to go w/ an integrated lightweight engine/exhaust/transmission that's more efficient and only ~100lbs heavier than a underpowered generator, bu as usual those are just my 2 cents.

i'm a newbe at this and i have been following your progress. i like the idea of taking your own charger with you just to keep the battery power up. i may want to try that too. be able to take it out to go the the dmv to show all electric and if ever stopped - its a backup power system.
my problem is im used to hot rods - so i want an electric hot rod - 400+ ftlbs to the rear wheels - 1st one off the light, first one to the next, and 80 mph on the freeway. so i am really interrested in how your build turns out.
good luck - well done so far.
