Fast charger comes to Voltageville: A Glimpse at the Future

In 2001 I began driving an electric car, obtaining the last of the ZEV mandate-required EVs. As I got turned on to the benefits and technological readiness of electric cars, the writing was on the wall and EVs began to disappear from California's roads. I got enthused just as the automakers, CARB, the feds, and major environmental organizations ended their various flirtations with EVs.

The notion of the plug-in hybrid revived the hope of plugging in. I made my peace with the notion of a transition vehicle, with a plug and an engine. GM announced the Volt.IMG_0561

Then a couple of years ago Carlos Ghosn had some sort of epiphany and announced Nissan's belief in the inevitable electrification of cars, and Nissan's intention to lead the transition. He defied conventional thinking by moving directly toward the commercialization of all-electric cars. Hundreds of thousands of Nissan all-electric cars would be manufactured in Asia, America and Europe within a very few years.

I was thrilled. Consumers would soon begin to have a choice of vehicle types that include real electric cars. The marketplace, rather than bureaucrats and academics, would decide whether EVs have a place.

Government and industry began to plan for the rollout of plug-in cars with a plan to roll out public charging infrastructure. Level II charging stations are great for opportunity charging while shopping or working and should be widely diffused. But there wasn't much discussion about faster charging options, as it entails additional obstacles of cost and lack of standards and a presumption that cars wouldn't be fast-charge enabled. Although I knew it was technically feasible, it seemed we would have to wait. Although fast charging stations could enable long distance EV driving and are one way to meet the needs of urban purchasers of EVs who don't have parking with access to electricity, it is logically not a matter of first priority.

But just as I was pleasantly surprised to find Nissan's LEAF in the offing, so too fast charging is going to appear more rapidly than expected. The DOE grant to the Etec EV Project will put 260 Level III chargers in the ground in the next two years. Nissan's LEAF will initially appear with a fast charge connector, something that will surely be a purchase option in the future. (And is some compensation for the slow 3.3kW Level II charger in the first cars.) The iMiev, should Mitsubishi do an American release, also has a fast charge connector. And Th!nk announced intentions to enable fast-charging in its cars in an agreement with Aerovironment.

Once again, I celebrate that consumers will have options as we work our way toward the best solutions for quick charging. Better Place has pushed its proposed solution to the range IMG_0559dilemna - battery swap stations. One car maker, Renault, is making cars to spec, and BP has demonstrated the battery swap device in Japan. Swapping out an empty pack for a full one is enticing. It's proven to be enticing to the tune of hundreds of millions of dollars. If swap stations can be commercialized and the batteries can be charged at Level II speeds and below, they too might offer benefits and be part of the clean transportation quilt. But essentially off the shelf Level III fast charge stations, capable of delivering near-to-full charges in under 30 minutes, can be put in service within months. A Level III fast charger can be installed for about $100,000, compared to millions for a hydrogen station and perhaps $1 million for a battery swap station.

Which finally brings me to the fast charger I saw the other day in Vacaville, CA. Installed by PG&E with funding from the State, it sits beneath a solar PV array amongst a handful of Level II chargers, including small paddles for RAV4 EVs, AVCONs for RangerEVs, and aTesla charge station. The fast charger uses a Japanese connector (an American standard remains under consideration) which was easy to handle. I wish I had gotten a photo of the complete line-up of chargers under the solar array, because it is evidence of real-world solutions, available now, to make plug-in cars and renewable electricity a reality quickly.

Wired blogger takes on Nissan LEAF

Darryl Siry blogs over at Wired's Autopia. He's pretty plugged in, having worked at Tesla and consulted for CODA. He's a bit surprised, as are all of us, that Nissan has emerged as the first big automaker to manufacture a mass-produced electric car.

In his recent post, "In Race to Market, Nissan’s Electric Car Takes Shortcuts," Siry makes the point that CEO Carlos Ghosn's enthusiasm and charisma alone couldn't be enough to get such a job done so quickly. He writes that the urgency of the project "appears to have driven the company to take some shortcuts."

Sounds ominous. Ultimately, I'm not sure what he's actually getting at. Because Siry makes only two points. Neither of certain significance.

First, he suggests Nissan overstates the range of the LEAF. The 100 mile range cited by Nissan uses "a number tied to the most optimistic benchmark, the LA4 cycle." I don't doubt that this is true. The LEAF pack has fewer kWh than my RAV4 EV, but could be almost as heavy. Until we get final specs on weight, and drive the car around a bit, we won't know to what extent people will need to handicap official range numbers as they do EPA gasoline mileage ratings. Big surprise, your actual mileage may vary. Buyer beware!

Second, and the point on which the article devotes most attention, is whether Nissan is "cutting corners" by forgoing an active thermal management (HVAC) system for the batteries. Instead Nissan is relying on air circulation with a fan.

Now I don't know whether something about lithium, regardless of chemistry or packaging, will prove to require an active system. But I do know, interestingly and perhaps relevantly, that the electric car that has probably driven more miles than any other model, the Toyota RAV4 EV, does not have batteries with an active system. A fan circulates air. The Honda EV+ used the same Panasonic EV-95 NiMH battery modules with an active system, and those packs didn't last as long. Many EV+ packs were exchanged during their brief time on the road. At least with NiMH, Toyota's passive system worked out better in the real world. Of course the cooling system may have had nothing to do with the the difference in performance of the same batteries in two Japanese EVs, but we'll never know.

Siry notes the different approach being taken by GM for the Volt. They reverted to the T-shaped tunnel configuration for the battery used in the EV1. (How did that work out?)

I may be approaching this too simply, but the tunnel has never made sense to me. It eliminates the possibility of a fifth passenger seat. And I find it makes me feel confined. The batteries, too, enshrouded on three sides, require, apparently, an active thermal management system.

The RAV, on the other hand, suspends the batteries below the vehicle. There is minimal loss in cabin space and a large surface below helping dissipate heat, which is an issue with NiMH, too. And we find that the LEAF's battery pack, too, will be located under the floorboard. Maybe that's the key. Keep the batteries low and spread them wide.

I don't know, of course, but I'm willing to give Nissan the benefit of the doubt.

I'm giving Tesla and CODA and GM the benefit of the doubt, too.

2010 Chevrolet Volt Price Depend on Gas Price

Volt price will depend on gas price, GM says.

Although the conference call was supposed to be all about the progress on designing batteries for the Chevrolet Volt, the issue of the car's price loomed large in observer's minds.

With a potential asking price that's risen from an estimated $30,000 (U.S.) to a loftier $40,000 for the compact four-seater, Bob Kruse, executive director of the program, gave no specifics on its estimated MSRP, but said the price will depend in part on the cost of gas.

"We're not wishing for higher petroleum costs, but the economic viability of what we're doing only gets greater with higher fuel prices," he said. The plan to launch the car in November, 2010, is on schedule. "$1.50 gallon gas is not helping our business case."

The average price of regular gas in the United States was actually $1.96 a gallon earlier this week, according to American government figures.


GM is not sure what the price of the Volt will be, Kruse said, nor has the company established whether it will lease the battery separately from the vehicle itself, as Nissan plans to do with its all-electric vehicle, which is to go on limited sale next year.

"Part of the price will be dependent on fuel costs at the time, which will impact the value equation the Volt provides."

The focus of the update was on the progress of the lithium-ion battery design — as GM has said, once the battery is ready, the Volt will be ready.

It is the advanced battery technology that allows the Volt to promise up to 64 km (40 miles) of electric-only driving; the small internal combustion engine works only to recharge the batteries, instead of stranding the driver, as would have occurred with GM's ill-fated EV1 all-electric vehicle at the end of its range.









"As we've seen with computers, the technology has progressed to the point where they have morphed from large desktop models, down to the size of your Blackberry," said Denise Gray, director of battery systems engineering, while confirming that design work on generations two and three of the Voltec system is happening alongside the production Volt.

"We're looking for the same types of advancements (and cost reductions) in our electronics."

In a Q&A session afterwards with various media, one astute questioner asked at what temperature those promised 64 kilometres of electric-only driving were verified. Turns out, it was the figure achieved in the normal city cycle testing, said Kruse, which is done at 20 degrees Celsius.

So if your winter commute involves regular sub-zero starts and highway driving, the question isn't whether its electric range will decrease, but by how much?















GM was obviously very sensitive about the fact that the battery cells for the first-generation Volt will come from South Korea, courtesy of LG Chem, especially when it is receiving extra money from both state and federal U.S. governments to produce environmentally advanced vehicles in and around Detroit, on top of the federal bailout money it has and will receive to keep it afloat.

The first batch of pre-production prototypes will be produced later this summer, about 80 of them, soon after the world's largest auto battery facility will open near Detroit, said GM.

Overhyped Nano on sale in India

In yet another media-frenzy-generating launch event, Tata Motor officials confirmed that orders will begin being taken in April in India for the Nano, whose super-low starting price of around $2,900 has media outlets around the world breathlessly reporting on the debut of the "world's cheapest car."

Except it's not the world's cheapest car, it's the world's cheapest new car.

Option it up with various luxuries like a right-side rear view mirror, heating and air conditioning, and a cup holder, and that price moves to 172,360 Indian rupees, according to figures available at tatanano.com, or the equivalent of $4,152.

Still, offering any new vehicle at such a low price is a remarkable achievement, even if the lack of airbags and emissions controls would not allow the Nano as is to be sold in most developed markets, and certainly not in regulation-heavy North America.










"The Nano represents the spirit of breaking conventional barriers," said Tata Motors chairman Ratan Tata. "It will provide safe, affordable, four-wheel transportation to families who till now have not been able to own a car." Or at least a new car.

The Nano offers a 35-hp. two-cylinder engine, coupled to a four-speed manual transmission, with a top speed of 105 km/h, for a published estimate of 33 seconds for the small four-seat hatchback to reach 100 km/h.

Plans are in the works to sell an upgraded version of this car to parts of Europe by 2011, the company said; it would a larger 90-hp, three-cylinder engine, available five-speed automatic, dual airbags, ABS and stability control, with a target starting price still under $5,000 (U.S.).

"Driven mainly by the change in demand that we see elsewhere in the world, we suddenly felt we had a product that could be of considerable interest as a low-cost product in western Europe, eastern Europe, the U.K. and even the U.S.," Tata told Reuters at this week's event.










Women's Car of the Year award launched

Female automotive journalists are a relative rarity in this business, but a group of 10 women auto writers from around the world will launch the first Women's Car of the Year award.

The initial group includes two journalists from Canada, as well as India, South Africa, the U.K., Australia and Europe.

"Most awards are chosen by a huge majority of men who tend to view cars differently to women," said Sandy Myhre, the New Zealand-based journalist who initiated the award.

"This award reflects changing times when you consider that today women make the final decision in as much as 85 per cent of all cars sold," according to Myhre.

After noticing that the 2007 World Car of the Year award's 43-member jury of international auto journalists did not contain one woman, Myhre helped organize a Women's COTY program in New Zealand last year, an award which went to the Volkswagen Passat BlueMotion (diesel) wagon.

"Newton-metres [or lb-ft] of torque weren't even considered, but we did look at drivability and sexiness," for those awards, as well as its carbon footprint, family friendliness, value, and, "of course," the range of colours, said Myhre.
Infiniti M to become brand's first hybrid

Playing some serious catch-up to arch-rival Lexus, Infiniti plans to start selling its own hybrid designs in North America next year, starting with its mid-size M sedans, Japan's Nikkei business daily reports.


While the Altima now offers a hybrid option, the hybrid uses leased Toyota hybrid technology, while Nissan, Japan's third-largest auto maker, struggles to come out with its own hybrid designs to rival those of Toyota and Honda.



Other luxury players are starting to jump into the hybrid market as well, with BMW and Mercedes-Benz both planning hybrid SUVs for North America and Europe this year, as well as the Mercedes-Benz S400 BlueHybrid that will compete with Lexus' top-line LS600hl.
