Not sure why you want to compare efficiency of filling a battery to anything. > 3. Last I heard FCV fueling infrastructure was wildly more expensive than > EV fueling infrastructure. I don't know the cost of EV fueling infrastructure or how best to compare (cost per car per day of infrastructure?), but H2fueling infrastructure is mostly very expensive. These have been built as one-off stations. The most recent bids to CEC show costs coming down, and people thinking in terms of multiple stations to further bring costs down. > > I'm trying to understand the business case for pursuing FCVs instead of the > seemingly more promising path of furthering advanced lithium chemistries. There are a number of chemistries being looked at, and IMO you shouldn't think if this as either/or. Batteries development has come a long way, and should continue, even if you think that FCEV will be dominant in the future. Batteries are important in FCEVs, and I would guess that the sizing of batteries v. fuel cells will change over time based on technology, costs and the application. Perhaps it would be better to think of FCEVs as hybrids. > The only plausible reason to pursue FCVs that I can think of is that it's > too easy for an upstart manufacturer (like that pesky Tesla) to become an > EV manufacturer.

Where's the return for Toyota? Is > there something new in FCV development that I missed? Only Toyota knows why, but given that most OEMs are moving in this direction either partially or fully seems to point to the need to question your assumptions. But maybe it's as simple as "consumer didn't buy them...end of story." I don't think it's that simple, but it's possible. I was surprised, too, about the RAV4-EV, but it's been clear for awhile that Toyota was going into FCEVs in a big way. > > Chris > > > On Wed, May 21, 2014 at 4:44 AM, brucedp5 via EV <[email protected]> wrote: > >> >> >> http://www.thedetroitbureau.com/2014/05/toyota-pulling-plug-on-rav4-ev/ >> Toyota Pulling Plug on RAV4-EV >> by Paul A.
