Renault LG Signing Ceremony

With most EVs getting around 100 miles on a single charge from their battery packs, such vehicles are more suited for the downtown core than a trip to the mountains. However, Renault and LG Chem are looking toward boosting range toward Tesla-like levels, together.

Yes, we know water is wet too, but this study from the AAA provides some interesting findings regarding how extreme temperatures affect the driving range of electric vehicles.

So-called “range anxiety” is the biggest — perhaps the only — issue being discussed in the electric-vehicle debate nowadays. Whether it’s a Leaf crapping out at the sixty-mile mark or a Tesla Model S driving in circles around a parking lot to drain the battery for theatrical purposes, electric cars and range potential are linked in the minds of most potential buyers by a true Gordian knot.

If the people at Phinergy are correct, that knot can be sliced by a sword constructed from charged aluminum plates — and the resulting rewards would be spectacular, to say the least.

The drama circling around the New York Times test of the Tesla Model S doesn’t surprise me one bit. Why? Because I understand, perhaps at a deeper level than most of the motoring press, how batteries work. Perhaps that has to do with growing up in a family of engineers and scientists, but battery technology has always interested me. So when people from Phoenix came to me crying in their soup about their LEAFs in the heat and friends started wagging fingers at Tesla and the New York Times, I figured it was time for a battery reality check.

Though an global Accenture study [via Green Car Congress] found that up to 68% of respondents would consider a plug-in electric vehicle for their next purchase, the issue of range continues to be the great unknown. And unfortunately for all the models and predictions of future EV sales, the issue of range points to some severely irrational consumer behavior. Namely, there’s a giant disconnect (nearly ten-fold in fact) between the actual number of kilometers driven each day and the range expectations for future EV purchases. Meanwhile, 62% of respondents rejected battery swapping, the most credible current solution for range anxiety, for reasons that are not immediately clear. In short, Energy Secretary Chu had beeter be right when he says EV range will triple and costs will be reduced over the next six years… otherwise, EVs will die a quick death at the hand of consumers’ outsized range expectations.

When I was a kid I was told that by the time I was 30 we would all be piloting nuclear powered flying cars. Reality, of course, has dictated that gasoline is still the most cost effective way of delivering what the average person considers a “normal driving experience.” In an attempt to change not just how we “fuel” a car, but the very way a car is integrated into our lives, Nissan has released the first volume produced electric car in North America. Yea, yea I know about the GM EV1, Toyota Rav4 EV and the Ford experiments, but let’s be real, Nissan has already sold more Leafs (Nissan tells me the plural is not Leaves) in the first few tsunami-effected months of this year than GM sold during the two years of EV1 production. How did they do it? We borrowed a white Leaf for just under three days to find out why 20,000 have already pre-ordered one of these pure-electric cars.

Hydrogen Fuel Cell vehicles (FCVs) are enjoying something of a comeback lately, as everyone from Hyundai and Honda to GM and Daimler are talking about forthcoming production versions of test-fleet FCVs. And with EVs poised to both dominate the short-term green-car game and inevitably disappoint consumers, it’s no surprise that the perennial “fuel of the future” is enjoying a fresh look from automakers. But if high cost and range anxiety are the flies in the EV ointment, the FCV-boosters are finding their hydrogen cars tend to suffer from the same problems. Daimler says

By 2015, we think a fuel cell car will not cost more than a four-cylinder diesel hybrid that meets the Euro 6 emissions standard.

but that by no means guarantees its Mercedes FCV will be truly “affordable” by any reasonable standard, as diesel-electrics are considered one of the most expensive applications of internal combustion power. And then there’s the whole range issue. Yes, FCVs refuel faster than EVs, but even the most ambitious of Hydrogen-boosters, Daimler, are only pushing vehicles with a 250-mile range. Which is why we puzzled a bit over The Globe And Mail‘s assesment that

Three Mercedes-Benz B-Class F-CELL models will make [a 125-day] global trek, which will seek to highlight the real-world benefits of fuel cells versus EVs – mainly their much further range

Flipping over to AutoMotorundSport, we find that the irony which completely escaped the G&M is threatening to overwhelm Daimler’s entire demonstration. And, as is only natural when things like this occur, there’s a bizarre TTAC connection…

The first time I came to Houston, TX, was  in 1986. The “reverse oil crisis” had brought the price of crude below $10, and Houston was a ghost town. In nearby Port Arthur, unused oil rigs piled up at the shore, and grass grew on downtown Procter Street. Now, Houston, home of the Petroleum Club (and some clubs the greater Baruth family would fancy), could become the model city for electric vehicles. According to plan, nobody will be farther away from a charging station than five miles, and you can charge up as much as your EV can eat for a flat monthly fee. (Read More…)

Did you know that there’s an Electric Drive Transportation Association? It’s a group that wants you to ditch your ICE-powered car and run on battery instead. Their member list is huge. Just about every important automaker is on it. Utility companies  from Austin Energy all the way to the Tennessee Valley Authority are members. Battery manufacturers, component suppliers, infrastructure developers are members. The City of New York is. Hertz is. And if things get dicey, the association can call upon their member L-3 Communications-Combat Propulsion Systems to provide fire support.

But as big as they are, they are scared. They are worried that customers may not plug in. Or, as Reuters put it, they are concerned that “the ‘range anxiety’ drivers of plug-in electric cars may suffer is preceded by anxiety over the wisdom of buying one.” And what do they do to allay these fears? Cheaper cars? Longer lasting batteries? Free charging stations? (Read More…)

Yes, we know the drill: range will vary with an EV, even more so than with a gas car. Nissan has now set out a number of scenarios to project the range of its Leaf EV. It confirms what we’ve been saying all along: this is not the car to buy if you like driving fast. There’s little doubt that a Baruthian blast could deplete one in some 30 miles or less. On the other hand, if you like driving at a steady 38 mph… (Read More…)
