My Pedelec is 500WH (Trek Powerfly 5) and is good for in excess of 50km on "sport" mode for my commute/weight (mix of path, road, fire trail and single track with approx. 400m elevation gain, and an 80kg rider). I've pressed it out close to 60km but have sometimes knocked it back to "tour" when getting nervous about making it home. Though have never run out.
I haven't tried longer riding on "eco" to see what sort of range it gets as the Trek is more about fast fun than racking up kilometres. I have a roadie for that.

As a Mechanical Engineer (with a fair bit of automotive experience) I find the project quite interesting. I do wonder when you are getting up to these weights whether stripping down something like a Yamaha EF1000iS to it's bare essentials and customising a housing/fuel tank would be a good starting point.
