More electric cars trickle to market
The Green Ford
2012 Ford Focus Electric |
In 2012 Ford wants to capture their own part of this green mind-share. How are they going to get there? Ford is 4 years into a 20 year plan to increase fuel economy and electrify their vehicles. This plan includes a complete line of vehicle styles and drive-train options. Ford refers to this as "The Power of Choice".
Specifically in 2012, from Ford, you can expect to see:
- Focus Electric with a rating of 100 MPGe (compared to 99MPGe of the Nissan Leaf)
- C-Max Hybrid with a better MPG rating than the Prius V
- C-Max Energi with a better MPGe rating than the Plug-In Prius in EV mode
Ford says this is just the first of many steps that we can expect to see as they continue to roll out their 20 year plan. In 2013 Ford expects to produce more than 100,000 plug-in vehicles.

Chevy Volt Does Not Play Well With Others
2011 Chevy Volt |
In the decade that I have worked there, there have always been a few plug-in vehicles buzzing around the campus. These were either the odd 3-wheeler vehicle like the Gizmo or they were home conversions done by the too rare electrical engineer that can also turn a wrench.
Now that plug-in cars are for sale, there are many more than just the one or two EVs that had been around. To my employer's credit, they have installed charging stations to support their tech loving employees. They installed two charging stations that can charge two cars each, so four cars can be plugged in at once. However, there are about 14 plug-in cars on our campus.
As coworkers and as part of the EV community, we are willing to work together and share these precious charging spots. To facilitate this we have an email list and many of us have charging protocol cards on our dash. It has a paperclip that you can slide to indicate the time that your car can be unplugged and it has contact information so we can call each other to move cars when needed.
Usually, we don't need to move the cars. The EVSE cables are long enough to allow access to eight parking spots. Considering that on most days, most of us don't need to charge at work, this ratio of charging spots to EVs works well with the system of sharing that we have employed.
There is, however, one snag to our sharing scheme: The Chevy Volt. If you unplug a Volt without unlocking the car, the alarm will sound. This is true even if the charge is complete. To unplug it, this means that we have to call the Volt owner and have her unlock the car either by walking out to the parking lot or via her OnStar smartphone app.
Maybe it would be better to just disable the alarm temporarily, but according to her, unlocking the car is the only way to disable the unplug alarm.
Only one of the three Volt owners on campus charges at work. Ironically, since the Volt has a short EV range, relative to pure EVs, the Volt will need to be plugged in more often in order to avoid fuel use. This driver has a 30 mile one way commute. With a 60 miles daily commute, she is in the minority of people that drive more than 40 miles each day, so plugging in or not directly impacts her fuel use.
Unlocking your car when you are not there is an act of trust. It is one thing to extend this to a coworker while your car is in a parking lot with cameras. It would be another altogether to even consider this in a public parking area. This makes it nearly impossible to share a charging station.
I hope GM see the flaw in this design and creates a firmware upgrade that at least allows this to be user configurable.

Fast Charging in Portland
The connectors on the DCQCs are not as simple as the Level 2 chargers that most EV drivers have at home. There are two levers on the connector. The smaller of these two can easily be broken if not used correctly.
The three DCQCs currently in Portland are located: one, downtown at the World Trade Center; two, at Portland State on Electric Avenue; and three, on the east-side at the Hollywood Fred Meyer store. The only one of these three not to have had this problem is the World Trade Center system. It has an earlier design connector that is more robust.
The failing connectors are made by Yazaki Energy Systems. As I write this, the company has completed a redesign of their connector and it is currently going through certification. In the mean time, the broken connectors have been replaced with the fragile design that is currently approved.
So Portland is back to having three DC quick charge stations operating until one of them breaks again.
- When inserting the connector, do not squeeze the black handle until the connector is fully inserted into the receptacle.
- Do not squeeze the black handle with any significant force. If it doesn't move easily, the connector isn't inserted correctly.
- Once inserted, gently squeeze the black handle. It should move effortlessly. The back part of the blue handle moves forward towards the receptacle.

Consumers wary of buying electric cars
Before you use an EV on a regular basis, recharge time and range are concerns. This leads to comments such as, "I won't drive an EV until it can go 300 miles on a charge and it can refill as fast as I can at the gas station."

Renewable Energy Subsidies Are a Waste of Money
Let us never forget that the original patriots of the 1773 Tea Party threw overboard the product of an oppressive foreign nation and their East India Tea Company (EITC) who sought to relegate us to their servitude. Who severely misjudged the will of the American people for independence and misjudged their desire for tea at any price. A true modern day equivalent of a Tea Party acting in the spirit of those original patriots of 1773, would be one that threw overboard the product of foreign nations and their Organization of Petroleum Exporting Countries (OPEC) who seek to relegate us to their servitude. Who severely misjudged the will of the American people for independence and misjudged their desire for gasoline at any price.A true Tea Party patriot would “make their own tea” for the equivalent of $0.40 cents a gallon of gas, and not make populist moronic proclamations such as “if you elect me I’ll give you $2.00 a gallon gasoline.” How’s that for a loaded but true paragraph?

13 Key Questions and Answers about Nissan Leaf Battery Pack and Ordering | Hybrid Cars
If fast charging is the primary way that a Leaf owner recharges, then the gradual capacity loss is about 10 percent more than 220-volt charging. In other words, it will bring the capacity loss closer to 70 percent after 10 years."

Battery Capacity
1. Design Full Capacity - never used, no real way to tell, so not very important in day-to-day use.
2. Allowed Capacity - the part that Nissan allows us to use
3. Wall Capacity - the amount of energy required from the grid/wall/EVSE to charge the battery (maybe 26 kWh)
4. Charging Energy - after the losses in the LEAF's internal charger, the DC energy that is actually delivered to the battery pack (maybe 24.6 kWh, just a guess). The charger's efficiency is not usually as bad as people say.
5. Stored Energy - after modest cell heating and small chemical losses during charging (or Regen), the amount of energy that actually gets stored in the battery (maybe 24 kWh). The charger often gets blamed for this loss.
6. Recovered Energy - the real usable energy, significantly less than the Stored Energy (maybe around 21.4 kWh).

Charging Station Sharing
In most places, there are few if any charging stations. Plug-in cars like the Leaf and Volt are currently rolling off of assembly lines and into the hands of owners. Inevitably, there will be a case where you want to plug in your vehicle, but someone else is already there. If you really need to charge, is it OK to unplug them? If they have the charging protocol card, then at a glance you know how long they need to charge. If you need them to move their car for access, there might even be a contact phone number.
EV drivers are part of a community. A community that is working together to make the world a little bit better. You can be part of that community by sharing the limited infrastructure that we currently have. The card below helps to facilitate charging station sharing. If you drive a plug-in vehicle, print this out, grab a paperclip to mark the time and drop it on your dash when you are charging in public.

Kilowatts for Gallons
To extract one gallon of gasoline (or equivalent distillate): 9.66 kWh (maybe not all in the form of electricity*)
To refine that gallon: 2.73 kWh additional energy (maybe not all in the form of electricity*)
Total: 12.39 kWh per gallon.
*Roughly one-third of the energy content of a gallon of gasoline produced from California wells is input from natural gas. Less than 2/3's is net energy (probably a lot less!).
So I can get 24 miles in my ICE on a gallon of gasoline, or I can get 41 miles (at 300wh/mile) in my RAV4EV just using the energy to refine that gallon. Alternatively - energy use (electricity and natural gas) state wide goes DOWN if a mile in a RAV4EV is substituted for a mile in an ICE!

A Perspective from Portland, Oregon: Disincentive - electric car tax
Taxing a product before it has an opportunity to achieve the economic advantages of volume production is wrongheaded thinking. While the reduction in the consumption of gasoline is not only necessary, it is the likely effect of the market. But the state rather than considering tax shifting strategies needs to reconsider its tax structuring and its spending."

Three Plug-Ins: The Cost to Drive - KickingTires
The low price of electricity gives the Leaf an advantage in a commute for which it has enough range. Frankly, we expected the Volt to come in cheaper than the Prius Plug-In because the Chevy's electric-only range is roughly twice as great on the low end, predicted broadly as between 25 and 50 miles. In actuality, it went 25.6 miles and then switched over to gas power, where the price of premium gas added insult to injury. (We'll report on the Volt's and Leaf's winter ranges in greater depth in the future.) For a shorter trip, or if higher temperatures delivered longer EV-only range, the Volt might have cost less than the Prius."

EVs Plug In Free at Oregon's State Offices
House Bill 2207 will change this if it passes. It authorizes state agencies to provide electricity for electric motor vehicles. Oregon has taken several steps to encourage plug-in vehicles and this is one important detail.
There has already been one case in the state with a State Park Ranger that only had enough range in his converted EV to commute one way. So he asked if he could charge at work to have enough juice to make it home. The answer was "no", despite an outlet being conveniently near his usual parking spot. His supervisor had no guidance on this issue and wanted to be "safe". You can plug in your phone, computer, or iPod, but not your car. This ranger now drives his gas car to work rather than his electric vehicle.
This bill has a hearing on Wednesday, March 9. HB 2207 was proposed by the Committee on Sustainability and Economic Development. It would authorize state agencies to “provide electric power purchased at state expense for the purpose of recharging privately owned and publicly owned electric motor vehicles at state agency locations.” A state agency is defined as “any state office, whether in the executive, legislative or judicial branch.”
If you have jury duty in a state court or you need to visit the DMV to register your new plug-in car, you may be able to juice up your ride on Oregon's dime. Depending on how far you have driven and how long you are plugged in, a dime may be all that it costs.
The bill justifies the expense by saying “It is the policy of the state of Oregon to encourage the use of electric motor vehicles.” So how much will this cost the state and (more importantly) we the taxpayers? There is no provision in the bill to add charging stations. It only makes plugging in not a crime. So the only cost would be for the electricity itself. The state pays less than 10 cents per kilowatt-hour for electricity and it is projected that there will be less than one thousand electric vehicles in the state by the end of 2011. There is no significant cost to this, and there is not likely to be one anytime soon. Even if the goal of 1 million plug-in vehicles nationwide by 2015 is reached, there would be no significant cost to this measure.
The City of Portland has installed a few charging stations and they are giving away the electricity free with parking. However, these downtown parking spots are actually making money for the city. "How?" you ask. These spots are marked as plug-in vehicle only parking and they are a steady source of parking ticket revenue. Now I am not recommending that the state pursue a similar model. Paid parking spots are uncommon in Oregon outside of downtown Portland.
This bill makes sense. No one should be prosecuted for using $0.25 worth of electricity. The state offices can turn off any outlets that become problems, were such trouble to ever arise. If this electricity helps displace gasoline use, it makes the air cleaner for all of us. This is especially important in places like a state park where you want to enjoy nature and get away from the pollution.

Commentary: Let road user tax be simple
But this takes a lot of technology, not to mention a debate about surveillance and tracking and Big Brother and all that.
How about keeping it simple instead and requiring owners of registered electric vehicles to report their mileage once a year? Along with the mileage report they’d remit the tax.
The proposed fee is 0.6 cents per mile (less than half the average for motor vehicles so as to encourage the use of electric rigs). If somebody reports that his two vehicles together ran for 18,000 miles since the last report, he’d remit the $108 in tax.
It’s not without its drawbacks. But if the penalty for stiffing the state and their fellow highway users is high enough, electic vehicle owners, a responsible bunch, would surely make sure that they pay their share."

Patent encumbrance of large automotive NiMH batteries - Wikipedia, the free encyclopedia
Patent encumbrance of large automotive NiMH batteries
This article needs attention from an expert on the subject. See the talk page for details. WikiProject Automobiles or the Automobiles Portal may be able to help recruit an expert. (February 2010) |
The patent encumbrance of large automotive NiMH batteries refers to the encumbrance of the commercialization of nickel metal hydride (NiMH) batterytechnology by corporate interests in the early 1990s and 2000s. Nickel metal hydride battery technology is important to the development of battery electric vehicles (BEVs or EVs), plug-in hybrid electric vehicles (PHEVs) and hybrid electric vehicles (HEVs).
[edit]Background
The modern nickel-metal hydride (NiMH) electric vehicle battery was invented by Dr. Masahiko Oshitani, of the GS Yuasa Corporation, and Stanford Ovshinsky, the founder of the Ovonics Battery Company.[1] The current trend in the industry is towards the development of lithium-ion (Li-Ion) technology to replace NiMH in electric vehicles. Some manufacturers maintain that NiMH batteries are important to the commercialization of plug-in hybrid electric vehicles (PHEV)s and battery electric vehicles (BEVs) because Li-Ion technology, while functionally superior due to its higher specific energy and specific power, is prohibitively expensive and relatively untested with regards to its long-term reliability.[2]
[edit]General Motors and the US Auto Battery Consortium
In an interview in the 2006 documentary Who Killed the Electric Car?, Ovshinsky stated that in the early 1990s, the auto industry created the US Auto Battery Consortium (USABC) to stifle the development of electric vehicle technology by preventing the dissemination of knowledge about Ovshinky's battery-related patents to the public through the California Air Resources Board (CARB).[3]
According to Ovshinsky, the auto industry falsely suggested that NiMH technology was not yet ready for widespread use in road cars.[4] Members of the USABC, including General Motors, Ford, and Chrysler, threatened to take legal action against Ovshinsky if he continued to promote NiMH's potential for use in BEVs, and if he continued to lend test batteries to Solectria, a start-up electric vehicle maker that was not part of the USABC. The Big Three car companies argued that his behavior violated their exclusive rights to the battery technology, because they had matched a federal government grant given to Ovonics to develop NiMH technology. Critics argue that the Big Three were more interested in convincing CARB members that electric vehicles were not technologically and commercially viable.[3]
In 1994, General Motors acquired a controlling interest in Ovonics's battery development and manufacture, including patents controlling the manufacture of large NiMH batteries. The original intent of the equity alliance was to develop NiMH batteries for GM's EV1 BEV. Sales of GM-Ovonics batteries were later taken over by GM manager and critic of CARB John Williams, leading Ovshinsky to wonder whether his decision to sell to GM had been naive.[3] The EV1 program was shut down by GM before the new NiMH battery could be commercialized, despite field tests that indicated the Ovonics battery extended the EV1's range to over 150 miles.[3]
[edit]Chevron and Cobasys
In 2001, oil company Texaco purchased General Motors' share in GM Ovonics. Texaco was itself acquired by rival Chevron several months later. The same year, Ovonics filed a patent infringement suit against Toyota's battery supplier, Panasonic, that ultimately succeeded in restricting the use of its large format NiMH batteries to certain transportation uses.[5] In 2003, Texaco Ovonics Battery Systems was restructured into Cobasys, a 50/50 joint venture between ChevronTexaco and Ovonics, now known as Energy Conversion Devices (ECD) Ovonics.[6] Chevron's influence over Cobasys extends beyond a strict 50/50 joint venture. Chevron held a 19.99% interest in ECD Ovonics as of a public filing made January 15, 2003.[7] In a later filing on May 17, 2005,[8] Energy Conversion Devices announced that they had exercised an option to purchase back 4,376,633 shares of stock from a Chevron subsidiary, and would cancel and return them to authorized-unissued status. This is the exact number of shares that was listed as owned by ChevronTexaco in the January 15, 2003 filing.
ChevronTexaco also maintained veto power over any sale or licensing of NiMH technology.[9] In addition, ChevronTexaco maintained the right to seize all of Cobasys' intellectual property rights in the event that ECD Ovonics did not fulfill its contractual obligations.[9] On September 10, 2007, ChevronTexaco (now known as simply "Chevron") filed a legal claim that ECD Ovonics had not fulfilled its obligations. ECD Ovonics disputed this claim.[10] The arbitration hearing was repeatedly suspended while the parties negotiated with General Motors over the sale of Cobasys back to GM. As of March 2008, no agreement had been reached with GM.[11]
Cobasys contracts demonstrated that the company was willing to sell smaller NiMH batteries (less than 10 amp-hours) for use with hybrid electric vehicles (HEV). For instance, in March 2007, GM announced that it would use Cobasys NiMH batteries in the model year 2008 Chevrolet Malibu hybrid.[12] Toyota uses NiMH batteries in all of its HEV models. However, Cobasys' sales policies raised questions about its willingness to sell larger format batteries for use in EVs and PHEVs.
In her 2007 book Plug-in Hybrids: The Cars that Will Recharge America, Sherry Boschert argues that large-format NiMH batteries (i.e., 25 amp-hours or more) are commercially viable but that Cobasys would only accept very large orders (more than 10,000) for these batteries. The effect is that this policy precludes small companies and individuals from buying them. It also precludes larger auto manufacturers from developing test fleets of new PHEV and EV designs. Toyota employees complained about the difficulty in getting smaller orders of large format NiMH batteries to service the existing 825 RAV4 EVs. Since no other companies were willing to make large orders, Cobasys was not manufacturing nor licensing any large format NiMH battery technology for automotive purposes. Boschert quotes Dave Goldstein, president of the Electric Vehicle Association of Washington D.C., as saying this policy is necessary because the cost of setting up a multimillion dollar battery assembly line could not be justified without guaranteed orders of 100,000 batteries (~12,000 EVs) per year for 3 years. Boschert concludes that, "it's possible that Cobasys (Chevron) is squelching all access to large NiMH batteries through its control of patent licenses in order to remove a competitor to gasoline. Or it's possible that Cobasys simply wants the market for itself and is waiting for a major automaker to start producing plug-in hybrids or electric vehicles."[13]
In an interview with The Economist, Ovshinsky subscribed to the former view. "I think we at ECD made a mistake of having a joint venture with an oil company, frankly speaking. And I think it's not a good idea to go into business with somebody whose strategies would put you out of business, rather than building the business."[14] In the same interview, however, when asked, "So it’s your opinion that Cobasys is preventing other people from making it for that reason?", he responded, "Cobasys is not preventing anybody. Cobasys just needs an infusion of cash."
Critics also argue that historical evidence demonstrates the willingness of the oil industry to engage in such anti-competitive behavior. In 1949, the U.S. Supreme Court found Chevron (then known as Standard Oil of California) guilty of conspiring to buy and dismantle the Los Angeles electric street car system, in what became known as the Great American streetcar scandal.[15] In an effort to prevent the passage of California's zero emission mandates in late 1993 and early 1994, oil companies also funded a series of ads that questioned the viability of electric vehicles.[3]
Cobasys' problems with other potential customers also raised questions about the company's sales policies. In October 2007, International Acquisitions Services, Inc. and Innovative Transportation Systems AG filed suit against Cobasys and its parents for refusing to fill a large, previously agreed-upon order for large-format NiMH batteries to be used in the Innovan electric vehicle.[11] In August 2008, Mercedes-Benz sued Cobasys for again refusing to fill a large, previously agreed-upon order for NiMH batteries.[16]
[edit]Current status of the Ovonics battery technology
Multiple companies have tried to develop NiMH battery technology without making use of Ovonics' patents. Electro Energy Inc., working with CalCars, converted a Toyota Prius from a hybrid electric vehicle to a PHEV using its own bipolar NiMH batteries.[17] Plug-In Conversions uses Nilar NiMH batteries and the EAA-PHEV open source control system in its Prius PHEV conversions. These organizations maintain that these developments are allowable because their NiMH battery technologies are not covered by Cobasys' patents. However, these batteries did not become commercially available until late 2007.[18] The technical capabilities of current bipolar NiMH technology are also significantly more limited than those of the ECD Ovonics technology. For example, the operating temperature range for ECD Ovonics NiMH batteries, an important consideration for their use in consumer road vehicles, is -30 to 70 degrees celsius,[19] while the operating temperature range for Nilar's bipolar batteries is a more limited -6 to 52 degrees celsius.[20]
On July 28, 2009, Automotive News reported that Cobasys would be bought from Chevron and Energy Conversion Devices by battery maker SB LiMotive, a joint venture of Bosch and Samsung.[21] At the time of the 2009 Cobasys sale, control of NiMH battery technology transferred back to ECD Ovonics.[22] In October 2009, ECD Ovonics announced that their next-generation NiMH batteries will provide specific energy and power that are comparable to those of lithium ion batteries at a cost that is significantly lower than the cost of lithium ion batteries.[23] It is unclear whether ECD Ovonics will continue to adhere to Cobasys' prohibitive minimum order sales policy.[citation needed]
