Is Greater Range Around The Corner For Electric Cars?

2013 Honda Fit EV CAPTIONS ON | OFF

Ordinarily, we don’t accept electric cars for test-drives on our home ground. For good reason, too: Living in an apartment, we have no way to charge a battery-powered vehicle. Neither is there any provision for charging at my office. As a result, only at Preview Drives for new models, and during special media events, have I been able to experience the growing crop of electrics.

Therefore, when offered an opportunity to drive a fully-charged Mitsubishi I (formerly named i-MiEV), delivered in that condition by truck, we immediately said “yes.” Even better, we learned that there’s now a public charging station at a Walgreens drugstore, barely more than a block from home. Even though I’d driven the “I” for several hours at a media program a year earlier, this would be a most helpful trial of real-world electric-car use.

Mitsubishi’s electric car, certified by the Environmental Protection Agency, promises an estimated range of 62 miles – not all that much, but sufficient to get most drivers to work and back without concern. That’s the theme used in electric-car advertising, pointing out that most commuters can easily make a round trip without recharging.

Yet, after starting off with a fully-charged battery pack and driving just 22 miles through light suburban traffic, the indicator showed that only half of the battery’s capacity remained. Had we continued onward, then, we may well have run out of electricity after only about 45 miles – far short of the published range.

Sorry, that just won’t do. Even a confirmed electric-car advocate, such as myself, began to worry as that indicator dropped to the halfway mark, threatening to keep sinking fast. Furthermore, after connecting the Mitsubishi to that 220-volt charger at Walgreens, I ambled across the street for a leisurely coffee. Returning after about 1.3 hours, the charge indicator had risen from the halfway mark to less than three-quarters. Even at 220 volts, it’s a slow process.

Most EVs claim driving ranges well below a hundred miles; and that’s only if driven under light-load conditions. Of the subcompact electrics now on the market, Mitsubishi has the shortest range estimate, but the competitors aren’t much better. The NissanLeaf gets an estimate of 73 miles (Ed. Note: but should improve drastically, soon). The FordFocus Electric promises 76 miles. The new Honda Fit EV manages an 82-mpg estimate.

Heading that small-electric pack is the less-known CODA, with a claimed potential range of up to 125 miles. At the recent Plug-In 2012 Conference, experts determined that a range of at least 120 miles is needed to eliminate “range anxiety” for most people.

The far bigger, costly Tesla S, somewhat surprisingly named Car of the Year by Motor Trend magazine, is the only electric passenger car on the market with a range that reaches well into triple digits. Specifically, Tesla claims a range near 300 miles (at a steady 55 miles per hour) for its top-end model, priced at $77,400. Two less-pricey Tesla S sedans, with reduced battery capacity, have claimed ranges of 160 and 230 miles.

Electric cars have been around for more than a century, but all along, range has been the big trouble spot. In order to boost electrics into serious contenders, a big breakthrough has been needed. So far, it hasn’t emerged. Instead, electric-car batteries have been tapping at the window of potential range, when they should have been shattering that barrier and roaring forward.

At least one prominent antique-car collector has suggested that big, early electrics – such as the Baker – could go nearly as far as today’s lightweights.

Digital Trends reports that Toyota is developing a sodium battery with a potential range up to 600 miles. Sounds exciting, but claims of vast battery improvements have been made over and over. In reality, most have resulted in far more modest increases, if they came into existence at all. So, it would be prudent not to get too worked up about Toyota’s research until a lot more data has been acquired.

Tesla Will Deliver Electric Model S Sedan In June, Stock Price Jumps

2012 Tesla Model S CAPTIONS ON | OFF

Electric automaker Tesla Motors pleased investors Wednesday, announcing that their heavily-anticipated Model S sedan will begin delivery this June. It had previously been schedule for July deliveries. Tesla will begin delivering the first Model S sedans as soon as the car passes government crash testing in the coming weeks.

The news boosted Tesla stock by as much as 13% at one point Thursday.

More than 10,000 customers have placed reservations for the Model S, and Tesla expects to deliver about 5,000 of the cars in 2012. Each reservation costs $5,000 (the Model S Signature Performance reservation costs $40,000). Tesla says all reservations are refundable, and you can click here to configure one of your own.

Tesla embarks on its most important launch ever during a shaky time for electric automakers.

Fellow American electric automaker Fisker began delivering their electric-hybrid Karma last year, and plan to build a new SUV model, the Atlantic, soon. Despite a sales rush for the Karma, however, Fisker has hit a bumpy patch financially. They recently fired twelve workersfrom their Delaware plant, where they had released 26 employees earlier. Now, they’ve had a $529 million federal grant suspended and adjusted 2012 sales projections from 15,000 to 10,000.

Tesla knows Fisker’s pain. Their first model, the Lotus-based Roadster, was a performance success but nearly sank the young company financially. After a personal loan from CEO Elon Musk, it still took hundreds of millions in Department of Energy grants and heavy investment from Daimler just to bring the Model S to production.

The Model S figures to be another on-road superstar. The base Model S, powered by 40 kWh batteries, is expected to reach 0-60 mph in 5.6 seconds with a charged range of 300 miles. A 60 kWh battery setup is also available, and the 85 kWh drivetrain could be as fast as 4.4 seconds from 0-60 mph.

But Model S delivery hardly means Tesla is in the financial clear. The company reported a $89.9 million net loss in Q1 2012, compared to a $48.9 million loss in the same period 2011. Revenue fell to $30.2 million, down from $49 million in 2011. The figures are largely based on the fact that sales of the Roadster recently finished.

Tesla expects that about 90% of the year’s revenue will come from Model S sales, and the decision to move deliveries up to June prompted them to adjust their 2012 revenue outlook. Tesla boosted their prediction from $550 million to $560-600 million.

Unlike the Roadster, the Model S is Tesla-made from the ground up, and will serve as a barometer for the health of Tesla in the future.

Tesla Unveils New Leasing Program For Model S

2013 Tesla Model S CAPTIONS ON | OFF

In an attempt to diversify purchasing options for potential customers, Tesla Motors yesterday unveiled a new 36-month leasing program for the popular Model S electric sedan that partners with banks and includes several key promises in the hopes of easing public fears about the cost of ownership.

So, how much? For the 60kWh Model S, only about $500 per month. Oh, excuse me. That’s if you factor in down payments, federal incentives, a guaranteed resale value, business write-offs, and gas savings. If that sounds like a lot of qualifiers, it is. The true out-of-pocket monthly payment is over $1,000 per month ($1,097 when I input figures that would relate to my hypothetical purchase — try it yourself here). Tesla shouldn’t be faulted for offering an alternative ownership method, but they do deserve scrutiny for skewing the numbers a bit. Then again, maybe this does turn out to be quite the deal. Does it make you more interested in buying a Model S?

After all, the Tesla Model S is not an affordable car. Nor should it be. The five seater is bloody gorgeous, blasts from 0-60 mph in about five seconds and has an all-electric range of more than 230 miles (up to 300 miles in some trims). It isn’t the car of the future, but it will probably lead to the car of the future, and that shouldn’t come cheap.

The problem is that Tesla wants to build the everyman electric car, but you can’t do that by making an expensive car appear affordable. They’ve already killed plans for the cheaper 40 kWh Model S, citing low interest, so why not just embrace that the Model S is an expensive car for people with the means?

Instead, Tesla is trying to put a price on things like gas savings and time savings and factor them into your monthly payment. Those benefits of owning a Tesla Model S are all well and good, but if I’m on the fence about buying one, they aren’t going to open my eyes and lead me down a new path. I already know about the benefits of a Model S or I wouldn’t be considering one in the first place. The Model S is a great choice for people who can afford one, but asking them to consider hypothetical pennies saved doesn’t seem like a great marketing strategy.

Which is a shame, because the lease offer is attractive. US Bank and Wells Fargo put up 10% for a down payment, which depending on your state is likely covered by tax credits anyway, and after the 36-month term your Model S will have the guaranteed resale value of a Mercedes-Benz S Class.

It’s not a bad deal. It’s just not the deal Tesla wants you to think it is.

Are Battery Buggies The Answer To Electric Vehicle Range Anxiety?

ebuggy mobility project CAPTIONS ON | OFF

Plenty of thought has gone into developing the current crop of electric vehicles, from the Tesla Model S to the Chevrolet Spark EV. Now, it’s time to concentrate more on the power infrastructure and on realistic needs of likely EV owners.

Because the driving range of nearly all EVs remains limited, they’re being consigned largely to commuter duty. That’s fine, but having a short-range EV then means owning an additional car for longer trips. For millions of cash-strapped families, buying and operating a single vehicle is tough enough. Budgets for the non-affluent simply won’t stretch that far.

Innovation is definitely needed, at least until true long-range EVs are developed and can be produced at affordable prices.

This year’s winner of the European Satellite Navigation Competition, the ebuggy mobility project, promises to be a “long-distance traffic solution for e-vehicles.” The competition was sponsored by the European Space Agency, European GNSS Agency, German Aerospace Centre, Nokia, and others.

The idea could hardly be simpler. An EV owner wishing to take a trip could start out with a full charge, but stop at one or more relay stations along the way. At the first one, the owner could hitch a battery trailer, fully charged, to the car and drive on. Trailers could be exchanged at regular intervals, dropping off the one with the depleted battery and then driving off towing one that’s fully charged.

When approaching one’s destination, the last ebuggy that was used may be dropped off at the final relay station. While at that destination, the EV can be driven using its own battery, charged in the customary way at local charging stations.

A satellite navigation system has been developed to manage such a trailer fleet of the future, monitoring and controlling movement of the battery trailers in “real time.”

Prototypes were constructed with the support of Germany’s Ministry of Economics and Technology and various partners, including Stuttgart University. At some point, ebuggy GmbH plans to develop the ebuggy battery trailer and relay-station network for series production. An international ebuggy network also is planned.

Practical? Perhaps. But a tiny bit tacky, too. Pulling a series of ebuggies would be rather like towing a little U-Haul trailer containing all your stuff.

Though feasible in Europe, this idea might not sell well in the U.S., with its longer distances between cities and points of interest. Yes, the network of public charging stations in the U.S. has been growing impressively, now thought to be topping 5,000 (Ed: The new Tesla Supercharging stations are particularly intriguing). But that leaves an awful lot of road miles across the country with no possible source for recharging.

Several trouble spots come to mind. If your EV has a range no greater than 75 miles or so, how do you arrange a trip if relay stations are, say, 50 miles apart? You’d have to stop at every single one and make an exchange. What if no ebuggies are available at a given station? You can’t just keep on driving. Such issues aren’t so crucial now, when only small numbers of EVs are in operation. But if and when that total grows appreciably, plenty of logistics questions pop into mind.

Still, ebuggy demonstrates the kind of thinking that just might make a difference, even if this particular proposal doesn’t really pan out on a widespread scale–or at all.

Pop The Hood: How The Tesla Model S Won Car of the Year

2013 Tesla Model S CAPTIONS ON | OFF

This week, the Tesla Model S became the first car to ever be unanimously chosen as the Motor Trend Car of the Year. It’s sexy and smooth, but the best thing about the Model S is undoubtedly its remarkable electric powertrain. Let’s see what makes it tick.

In the top-of-the-line Signature Performance trim, the 2013 Tesla Model S packs 416 horsepower and 443 lb.-ft of torque, and can achieve 0-60 mph in just 4.4 seconds. How does a 4,650 lb. car do all this without any gasoline? The obvious answer is of course, sorcery.

But the truth may even be more amazing. The Model S uses a liquid-cooled, lithium-ion battery that includes 7,000 battery cells for 85 kilowatt-hours (kWh) powered by an AC electric motor mounted between the rear wheels. Truly incredible stuff, but what does that even mean?

Well, it all starts with the 3-phase, 4-pole electric motor. The same one, in fact, that Tesla used in their previous Roadster model. A 3-phase, 4-pole motor generates a rotating electrical field at approximately one-fourth the frequency of the AC power supply. This technology was actually discovered by the company’s namesake, innovator Nikola Tesla.

There is an important designation here, because there are plenty of DIY electric car conversions out there that use a DC motor. DC motors are cheaper, but an AC motor places greater emphasis on performance, is safer, more simple to install and more adaptable to moving at different speeds. If a DC motor blows, it’s very likely to leave your converted car in a pile of burned wires. If an AC motor fails, the engine simply fails. No flames. No wonder, then, that the 85 kWh version will run you between $84,900 and $97,900. That’s the price of technology these days, but it’s also the price of whisper-quiet, zero emissions supercar performance.

Back to those 7,000 batteries. Panasonic supplied the lithium-ion cells for the Model S, which uses them as a flat part of the platform (rather than literally piecing thousands of laptop batteries together, like the Roadster did) to increase stability and balance. The cells are also liquid-cooled, constantly monitored to cool or warm the batteries so that they’re always operating at peak performance (and not exploding).

The cells connect to cathodes (electronic conductors through which current flows out) made of nickel-cobalt-aluminum. The most powerful kind of cathods are cobalt dioxide, but these are expensive as all hell and tend to – you guessed it – blow up. A nickel-cobalt-managanese setup lowers the cost, and makes it possible to tune for greater range or performance. Tesla elected to replace the manganese with aluminum, making it even more affordable.

Those cathodes send power to the wheels, which move an extremely lightweight all-aluminum body and high-strength steel frame through the air at just a 0.24 drag coefficient – the lowest of any production car. Full electric power with that kind of weight savings and drag comes out to about 89 MPGe and a 265-mile range. Does that make the 2013 Tesla Model S the car of the year? We’ll leave that up to you, but no matter what you think, you have to admit its technology is truly something to admire.
