    Nissan Leaf

    I think $25-33K purchase price range is too high for the LEAF. In essence, it is an electrified Versa, which goes for 13K-16.5K. Is the body + power electronics + electric motor really that expensive? Prius, which LEAF buyers will likely cross-shop, starts at $22.4K-27.7K. LEAF will likely have...

    Charging Station standards

    How much electricity to produce gasoline?

    My guess would be that electricity makes up a relatively small portion of upstream (exploration and production) energy costs. On the other hand, implications of 7.5 kWh/gallon refinery consumption are quite significant. As noted, an EV can travel 30 miles on this amount of electricity. A...

    Electric MINI revealed -- The Mini E

    Lot of "whining" about Mini E home charging unit installation in this Wired article. Did any Roadster owners experience "red tape" issues with HPC installation? Well, there is IEC 62196 (Mennekes) for the European part of the world. Also, I thought that committee was supposed to vote on...

    It's the Batteries, Stupid!

    We haven't yet discussed that Dow (a major U.S. chemical company) is moving into battery production "full steam ahead:" 1. Received $161M loan from DOE to build a battery manufacturing plant in Michigan 2. Acquired Kokam America's assets, makers of high capacity lithium polymer batteries...

    It seems common with all high energy density technologies. You can have either superior energy OR power density. Tesla managed to achieve good balance, but such solution is not cheap. Part of technology evolution maybe finding the right balance between two sources of energy with different...

    Lithium-air batteries

    AFAIK, this property was common to all metal-air chemistries for a while making such devices more "fuel cells" than "batteries" and limiting practicality (the infrastructure dilemma). However, very recently breakthroughs started to happen. In Europe ReVolt and BASF have joined forces this summer...

    Oil companies and alternative energy

    Excerpt from an article published by SAE in March, 2001: 8 years later Mr. Burns is out of his job and ExxonMobil keep singing the same old tune. I consider this a good development as the Big Buns are now signaling withdrawal of their support for Hydrogen Highway boondoggle.

    Loss of regen on a full charge

    Well, for scenario like yours instead of dumping excess regen energy I thought it would be possible to adjust standard mode to charge up to say 79.5%. This way extra .5% of battery pack would be available to absorb regen energy when starting downhill after unplugging the car. From your...

    Loss of regen on a full charge

    Hmm, perhaps turning on the cabin heater or AC either manually by driver or automatically by car when battery is "full" and regen braking is in place?

    Hydrogen vs. Battery

    Honda's soul-searching issues aside, what I really don't understand is their outright hostility to EVs. Yet another Honda president is talking about "thinking outside the box," but where is the evidence of it? The quirky U3-X or the dinky UV-N or the pie-in-sky hydrogen fuel cell NSX, which even...

    Hydrogen vs. Battery

    Funny he would say that. Perhaps he confused pounds and kilograms. I wonder what the weight of Clarity's battery is, for last I checked she weighed in at hefty 3,582 lbs vs Roadster's 2,723. Can't be all the lightweight hydrogen gear, right? 0-60 mph acceleration is heart-stopping 10 sec ;)

    Well, GM clearly wants all new charge infrastructure to be J1772 standard compliant, however they are not in position to use more assertive language like must or will. DoE, on the other hand, is.
