One criticism often leveled at BEV's is that large battery packs are environmentally costly to produce, and that the GHG cost to manufacture a BEV with large battery is 3-4x that of a typical ICE and that this accounts for the predominate GHG component over the lifetime of the car.
See http://www.designnews.com/author.as...dustry_auto,bid_318,aid_254150&dfpLayout=blog
which references a summarized paper here: http://www.issues.org/28.4/p_michalek.html
Here's another interesting pdf by same guy I found with some actual numbers http://esd.mit.edu/symp09/presentations/day3.session2c.michalek.pdf. This is primarily concerned with PHEV battery sizing, but also implies that a bigger battery doesn't mean least GHG lifetime emissions.
So is this complete FUD or is there merit here? Nissan's website claims no environmental difference in manufacturing the Leaf vs. comparable ICE - which I also find hard to believe.
Where are the other studies on this topic?
I'm primarily interested only in the issue of environmental cost of manufacturing the battery, not actual use (electric vs. gas). I apologize if this has been covered previously, but my forum search attempts failed.
Thanks.
