As they say .. YMMV
Good example .. people doing a conversion .. either need to know their specific context needs , or have plenty of surplus to cover whatever.
2nd gear ~3,500 RPM , ICE with some IMA assist on top (so you're up around ~40kw for the ICE+IMA combined) , in 2nd gear .. just for 40MPH .. , wow without a head wind that's like around ~28 degree slope .. for up to ~7 miles or so at a time .. you gained over ~3miles of elevation in 10 minutes ..
ouch that's a crazy combination of very steep and extremely long hill .. going up painful .. but equally holly cow , the going down that hill on the way back .. that's up near ~6.6kwh of potential energy getting converted back .. probably at least around ~5kwh of braking energy friction or regenerative , even my A123 IMA pack could only suck up ~2.5kwh of it ..
... ouch .. Glad I don't have several monster hills like that , in my driving.
