This is where regen comes in. While you won't get all your uphill energy back going down, it certainly does help. I've posted this link several times before. However, I think it's worth reposting, since it demonstrates pretty clearly the difference that regeneration can make in hilly regions - in this case, in the Alps. http://www.brusa.biz/index.php?id=43&L=1 According to Mapquest, it's 134 miles from Gams to Stabio. Not bad range for 1997, eh? This was Axel Krause's Mini-Evergreen with Saft NiCd monoblocks, not more exotic NiMH or lithium. The battery was 180v and 100ah, so drop-dead capacity was 18kWh. Assuming they used 90% of the capacity, that would be 121 Wh/mi - about half of what a typical conversion uses. The car weighed 900kg (~1980lb).
