Why One LEAF-Driving Cop Can't Drive Straight Home After Work Anymore

Garage Lessons: Charging in The Real World
For the past decade I've been driving the 91 miles to Sacramento without stopping to charge in a 2002 RAV4 EV. I suspected I wouldn't find a nearby available old RAV charger. Most have been replaced with units compatible with the new PEVs. So that day I was driving my LEAF. Less range but lots more public charging stations and fast-charging available.
I'd scoped out the closest garage with charging stations beforehand and hoped I'd find an available Level 2 charging station. The three in that garage were occupied by 8:30am, and I was pleased to see quite a few more PEVs parked in spaces without charging stations. Government workers who likely live close enough to not bother plugging in, I surmised. Or perhaps they just got beat out that morning and would have plugged in if the charge points were available since they are cost free.
Anyway, no time for idle conjecture; I was due at a meeting soon. I drove up through the 5 story garage hoping there might be some more charge stations elsewhere. There weren't. But what I did see, including on upper levels with few cars at all, were PEVs scattered throughout plugged in to 120V outlets. More cars were charging at these unintentional "guerilla" Level 1 charging stations than the "official" (and costly) Level 2 stations. What lessons are we to learn?Some might say, given the number of plug-in cars showing up in that garage, that it's time for more Level 2 chargers. I don't think so. Maybe some day, but not now. We have one mission: getting more consumers to buy plug-in cars. In Norway tax policy has resulted in the the world's quickest uptake of EVs. In October, more LEAFs were sold in Norway than any other model, gas cars included. We need to find other means to the same end. The Real World demonstrates that what's most useful and cost effective is more access to 120V outlets, perhaps lots more, at America's workplaces. It's simple and affordable by America's small and medium sized employers. And it's more than most drivers "need," actually.
Britta Gross of GM is reporting 70% of Volt customers charge at 120V. Nissan was surprised at the number of buyers uninterested in Level 2 at home, but we don't have real data. Nissan and the others ought to be required to reveal more data on how cars are charging. Relying on EVSPs gives us wildly skewed data that does not include Level 1 or EVSE-less Level 2. We already know that the real world charging experience is not exactly what was predicted and planned for. We need good information from the 10s of thousands of EVs on the road to help us make smart infrastructure decisions.
Where outlets exist already, as in that Sacramento garage, they need to be checked for safety and repurposed for EVs. It's the least expensive way to create a charge point and arguably the most powerful single carrot available to turn commuters into EV commuters and employers into willing accomplices. New Level 1 installations - outlets - will be the least expensive, lowest maintenance option - no EVSE. And they can be made Level 2 ready with proper wiring and conduit for the day five or ten years hence when EVs can partake of all the the "grid smarts" envisioned.
Later at the meeting I was told about what's happening at CalEPA. There are at least 28 Level 2 chargers in garages within one block of CalEPA, possibly many more. Yet there are so many PEV drivers now they've got a system to facilitate communication amongst themselves to enable the daily shuffle of cars to chargers during work so everyone can avail themselves of the free charge. Is that grass-rootsy EV driver success to apportion charge opportunities fairly? Or is it failure, taking state employees away from work, costing the state still more in the name of advancing plug-in vehicles? Is it reasonable to expect private employers to tolerate such a situation to promote EVs?
Back in the garage, I didn't find an available outlet. In the end I went to the hotel, which doesn't have any official EVSE but PlugShare reports does have a 240V outlet for EVs. So I pulled in, found the outlet, plugged in my EVSEupgrade.com unit, and charged up.The meeting was informative. Clever financing, electric public transport, and "interoperability" are important issues and a lot is gained from cross-national conversations. But right now Job One is increasing PEV sales. We ought to spend more time considering what will actually drive sales in the next year or two. "Interoperability," once we decide what we are talking about, and "smart" charging capable of providing grid services some day, will not sell one PEV now.
A 120V outlet with a welcome matt at one's workplace will. Surely there's a way to make that a priority.

Dong slams the box in the Danish electric car adventure
Seems the deal between Better Place and its Danish partner Dong Energy has gone south. BP Denmark has gone through the initial investment of 400 million kroner, and Dong denies an obligation to loan more.
"There are eroded cooperation between DONG Energy and Better Place Group," according to the story in epn.dk
Regarding additional funding of Better Place Denmark, "it is our choice. Not a promise, "says Torben V. Holm, Project Manager at Dong Energy.

What's the matter with Costco?
Costco, the big box retailer, has for over a decade been the business with more electric vehicle charge stations in more places around California than any other. Put in service during California's Zero Emission Mandate between 1997 and 2003 when about 6000 EVs roamed the streets, these charge stations have continued supplying power to the RAV4 EVs and other electric vehicles saved by Plug In America when it was known as DontCrush.com, a struggle chronicled in the film Who Killed the Electric Car. Costco's own magazine proudly reported in 2006, just as the film was being released, that 64 stores had a total of 90 charge stations.Now, Costco has the opportunity, thanks to the California Energy Commission's ReConnect California program with ClipperCreek, to upgrade legacy AVCON charging equipment to J1772 at no cost. As I see it, Costco's noteworthy and foresightful participation in California's earlier electric vehicle program will give them a deserved leg up on all the national retailers now looking into providing electric vehicle charging stations for their customers. While their competition is trenching through concrete and striking costly deals with new businesses long on promises but short on experience, at Costcos a quick swap-out could quickly give them the opportunity to tout the most extensive retail network of EV charging stations.
It seems, however, that Costco has chosen to look this gift horse in the mouth. The company has refused to consider the CEC grant to upgrade their charge stations for free. And it has actually begun to take out the chargers that it has, despite the fact that they have been used a lot by their own customers. Just take a look at an evchargermaps.com entry for a Costco with chargers. For example, the Mountain View location, a place I've charged and shopped at a few times a year since 2004. It has 44 reports going back to 2008. And dozens more going back to 2003. (This doesn't include every time someone charged, merely the times a driver made the effort to confirm the condition of the charger for other drivers.)
It has been reported that some store managers would rather not be removing chargers right when we see plug-in cars coming to market. Providing charging fits well with the company's sustainability efforts, including both the physical stores and the products they sell. President and CEO Jim Sinegal touts Costco as "one of the early companies to embrace many of the earth-friendly technologies, such as skylights and recycling" in it's Corporate Sustainability Report from 2009.
Why Costco isn't embracing their early support for plug-in cars now that the rest of the world is jumping in is beyond me. Given that it will actually cost the company more money to say no than to say yes makes this a no-brainer for me. It should for Costco as well.

Keepin' it simple

Plug-in cars are being delivered at long last. Yet there remains confusion about the necessary infrastructure and its expense. Electric Vehicle Service Equipment (EVSE) home wall units are priced at between about $1000 and $2500. Plus installation. Need it cost this much? Is it as complex and time-consuming a process as has been experienced by many new owners of plug-in cars?
All plug-in cars these days come with a 120-volt charge cord. This will actually be sufficient for many if not most Volt drivers, and quite a few LEAF drivers. An empty Volt pack will take 10 hours to fully recharge; an empty LEAF about 20 hours. That may seem like a long time, but the relevant questions are: How long will the car be sitting anyway? Until the next morning or just an hour or two? How full is the battery when it gets parked? And where are you going next?
For most folks most of the time, chances are the battery isn’t near empty when it gets plugged in, perhaps at work, perhaps at home after work. Recharge time will usually be much less than what it takes to go from empty to full.
And the cost to the consumer to enable the 120V cordset? If you’ve already got a grounded 120V outlet in the garage or carport, zero. If you need to put an outlet in a convenient place, it would likely cost about $100.
Surprising to many, including I suspect Tesla Motors itself, they found that about half the charging of Roadsters at home in the U.S. is at 120V. Despite the fact that it takes 38-60 hours to charge a Tesla from empty to full at 120V. One can’t presume the peculiarities of a Roadster tell us too much about plug-in cars with much less range, but I think we shouldn’t write off 120V charging just yet, as many involved in readying infrastructure for EVs would have us do. The cord that comes with the car just might suffice for many, especially plug-in hybrids which have smaller battery packs.
Still it remains true that most will want the ability to charge their car at a faster clip at least some of the time, which is what 240V charging stations provide. With the 16 amp charger both cars have today (the actual charger is located in the car, not the box on the wall,) a 240V EVSE takes about four hours to fill an empty Volt pack. It takes about seven hours to fill a near empty LEAF, ensuring a complete charge overnight. If a complete overnight charge is the goal, 120V will still suffice for a Volt, but a 240V EVSE will be essential for most who buy an all-electric car.
Nissan and GM have each had their preferred provider for home charge stations in an attempt to streamline the process, but many customers have had complaints about the cost and scheduling. Dozens of manufacturers seem to be selling equipment at a range of prices, but few actually are available now. The situation for new owners has also been complicated by the various government infrastructure programs, including the DOE-funded EV Project (Ecotality) and ChargePoint America (Coulomb,) which have differing requirements and benefits depending on one's vehicle and location. If eligible, most people accept a free 240V charge station, of course, as I did. My installation was pretty simple, so it cost me nothing. But government support for infrastructure won’t last forever. Coulomb and Ecotality sometime soon won’t be able to leverage taxpayer money to keep other manufacturers at a disadvantage. Quite likely not beyond the current programs.
I am pleased to participate in the EV Project, which came late to the San Francisco Bay Area, and happy to get my tax-payer funded charger and DC Fast port. I believe in government support for electric vehicles (and many other things also on the congressional chopping block at the moment.)
However, for the last month my Blink has been on the blink. Something about firmware, they said. An email on June 8th said they’d get back in touch to schedule a visit. As I write on July 13th I’ve recently been contacted by the contractor who installed the unit, but I’m still waiting for the service call. However, I remain unconcerned. Not because I always charge at 120V mind you. Rather, because I’ve had the 120V cordset provided with the car upgraded to 240V. EVSEupgrade.com offers the upgrade, which allows the Volt or LEAF to charge at their maximum 240V capability of 16 amps. Cost of upgrade: under $300. (For this to work in place of a wall-mounted unit, you still need a dedicated 240V 30 amp circuit and outlet, which would cost a few hundred dollars of an electrician’s time and perhaps $50 in parts.)
The point isn’t simply to plug the good folks at EVSEupgrade.com, although I’m happy to do it. They’ve kept my LEAF juiced, after all. Something Ecotality couldn’t do even with $100 million in federal grant money.
I am not alone in my concern that there is some level of unnecessary complication, excessive cost, and unhelpful mystification going on around electric vehicle infrastructure. It isn’t helpful to the “cause,” those picking up their new plug-in cars or those who are considering it.
For the electric vehicle project, broadly speaking, to be successful, we need to be mindful to keep it simple and keep it cheap. This is not rocket science. We are adding yet another electrical appliance to our ever increasing array of devices, from light bulbs and cell phones to refrigerators and HVAC systems. It needs to be done safely, of course. But it needs to happen. To do it right, the focus needs to be on consumers’ interest. The result will be simple, safe and cheap. Thank you evseupgrade.com for pointing the way.

From Scooters to High Speed Rail, China is Electrifying
I’m sure I’m not the first to say it. China is electrifying.
When I was studying China and Mandarin Chinese 35 years ago, “Red” China was unrecognized by the US, literally, and dark in a way difficult to imagine now. Who knew what was going on over there? Was “reality” that the world’s oldest civilization was throwing off the shackles of Western domination and its own past to offer a new vision of civilization, or was it bodies floating downriver to Hong Kong during the Cultural Revolution?

Just as today we can look at a nighttime satellite image and see the black void that is recalcitrant, unelectrified North Korea, once that was China. Today China is as illuminated as the rest of the world, and they are carrying electrification further. I can’t cite the government decree, but having just returned from two weeks that took me from Beijing to Changsha, Hunan to Shanghai, it is evident that a national transportation system is being implemented, and electrification is at its core. From two-wheeled scooters, a mainstay of urban mobility, and urban mass transit, to high-speed inter-urban rail, China will soon see the day most people move about most of the time on electricity. Fifteen years ago Shanghai was a city of diesel busses and bicycles. It had few private cars. For a while, gas scooters held sway piled high with people and products. It had no subway system. Today Shanghai has the world’s largest. Smoother and quieter than any I’ve ridden anywhere. And three types of electric busses - legacy trolleys with catenary wires, battery busses, and super capacitor busses. And most of
the scooters are now electric. (And they are headed directly at you, at night, with no headlight.)

Not very many years ago, tens of millions of Chinese packed themselves regularly into unairconditioned, slat-seatted box cars to get to work and visit family during holidays, enduring trips of more than 24 hours. I’m sure there are still plenty of old-school trains about, but today Chinese are boarding comfortable, high speed electric trains coursing on unimpeded raised trackbeds at over 200 MPH between cities large and ever-larger. Last year it took 24 h
ours to go from Beijing to Guangjou. Next year it will take 6 or 7.
With these dedicated high speed electric rail lines crisscrossing the nation, and the huge, attractive new train stations being opened to serve these inter-urban lines, it becomes clear China has decided most long distance passenger travel will be by electric trains. And these trains are being integrated with existing and new subway systems. Step off one system right onto the other.
Cars will undoubtedly be the last piece of the electric transportation matrix in China. The week I was in Shanghai, the Electric Vehicle Test Drive Center opened to the public in Shanghai Automobile City, a far suburb still reachable by subway. Plug-in cars from a half dozen Chinese automakers were on display along with charge stations in an attractive setting amidst a winding course for test drives. The BYD plug-in hybrid I drove performed well. I have no doubt we will see Chinese brands in the US when they are ready to make a move. While I think selling gasoline cars by the tens of millions to the domestic market is perceived to be of prime economic importance, I hope they choose to forgo following the Japanese and Korean model of aggressively competing on the low end in the export market. We really don’t need more cheap gas cars. With some attention to fit and finish, the Chinese could use their low-cost advantages (labor and a huge battery industry) in a market segment that sells at a premium outside their borders. Once EVs are cool in the West, the Chinese domestic market will follow.
China is very much a work in progress. As progressive and foresighted as they seem to be on the transportation front, they’ve got huge challenges ahead regarding electricity production. Largely dependent on domestic coal, cities are smothered in smog. Beijing, which systematically restricts automobile usage and moved a lot of factories out of town for the Olympics, had clearer skies than I expected. But it is an anomaly. Shanghai and Wuhan are enshrouded in poison.
Factories, including a solar panel plant I know of, have had to curtail production because coal can’t be shipped fast enough to supply electricity generation plants. Transportation of freight, including coal, will be relieved by moving passengers off the freight path and on to the growing high speed rail network. But that only postpones the reckoning that will come with the growing power demands of a burgeoning consumer culture.
China may end up with the world’s most efficient electric transportation system powered by the world’s most toxic electrical generation.
We, in contrast, may end up with an efficient, relatively clean, partially renewable electrical grid, while still burdened with a transportation “system” dependent on trucking freight and moving passengers on petroleum.
