i did not bother digging through the paper, but i wonder if the hybrid to all electric numbers where normalized? while these number don't surprise me this is only only one study. if the numbers hold one explanation might be that 60-90 mile range really is enough for the vast part of the population and hence don't need to charge outside the house that much. where as the plug-in hybrids' 20-40 mile electric-only would need more charging stations if the owners don't want to use gas. so what the study might be suggesting is that people feel they need to carry around a security blanket that weights a few hundred pounds

It stands to reason, since electric-car drivers are entirely dependent on their battery whereas hybrid drivers, who also have a combustion engine, don't need to plug in at every opportunity. Well, it turns out that the reverse is true, as I heard from Ravi Brar of ECOtality, a maker of electric vehicle chargers part-owned by ABB, at the Automation and Power World event in Orlando. Pilot project learnings Brar was presenting findings from the EV Project, a $230 million EV infrastructure pilot in the US whose participants either own a Chevy Volt, a hybrid, or a Nissan Leaf, a pure battery vehicle. Half of the funds are from ECOtality and its partners, and the other half from the Department of Energy, which is also why the data that is collected is publicly available on the EV Project website. http://www.theevproject.com/documents.php "Interestingly, owners of plug-in hybrid electric vehicles, even though they are carrying around a combustion engine with them, have a higher propensity to plug in their cars to recharge when they are out and about," said Brar. Volt drivers , he explained, use chargers on average 1.4 times per outing, compared with 1.1 times for Leaf drivers. http://www.theevproject.com/downloads/documents/Q4%202012%20EVP%20Report.pdf (must see report) Unexpected consequences This surprising learning from the EV Project leaves me with two thoughts. One is that the current trend at car manufacturers toward hybrid-electric models rather than electric-only vehicles may actually increase demand for charging infrastructure around the world, and thereby support the transition to all-electric vehicles in the longer term. Take note of this, all you prevaricating buyers out there. The other is that it's the consumer who decides how to use a technology, not its provider. It's a basic insight but it's easily forgotten. I wonder how many new products have fizzled because the R&D department or the marketing team thought they knew best, and how many have succeeded in ways no-one had expected? Ing.
