'We would have really liked to have loved it,' David Champion, director of Consumer Reports auto test center told Reuters on Monday after announcing the organization's top picks for 2011."
The same remorse and disappointment some of us experienced when the EV honeymoon ended is spreading to the regulatory world, as cash-poor states begin to grok that electric vehicles don't participate in the road-repair revenue gathering known as the gas tax."

Alternative Fuels and Advanced Vehicles Data Center: Oregon's Plug-in Vehicle Activities and Processes
Oregon's Plug-in Vehicle Evolution
Oregon has supported alternative fuel vehicles (AFVs) since 1991, when it established AFV tax credits, and recently began focusing on plug-in vehicles as part of greenhouse gas (GHG) reduction efforts."

Its benefits significantly outweigh its costs to users.
It’s already proven. It works and the technology has already established a beachhead in some rapidly recovering market.
It’s not controlled by a start-up which has to have a lot of stars align to work out. The big industry leaders have already deemed it the future."

According to Edmunds.com, the hybrid truck, which was on display at the Washington D.C. Auto Show last week, was partly funded by a $48-million grant from the U.S. Department of Energy. Edmunds said the 12 kWh battery is paired with a 5.7-liter HEMI V-8 and beats typical fuel economy for such a vehicle by 65 percent."

Electric, apparently, is also the pick of the Obama administration. In his 2011 State of the Union message, the president said, “The goal is to have everyone driving electric cars by 2030.” To skew the market toward that goal, the government offers a $7,500 tax incentive to buy the cars"

A big theme this year will be cars. There are some initial signs of economic recovery and there is a pent-up demand for new vehicles. This coupled with the new disruptive cars with cords and there are plenty of companies that want you to think of them first when you look at your dented ride this spring and think I want a new car.
A couple of these commercials have had an early Internet release to add to the build up. One of my favorites is a car commercial that does not even show the car.
GM will be showing the innovative American spirit that is behind the Chevy Volt.
These two commercials and all the Super Bowl XLV ads will be competing to stand out above the noise. One commercial that did just that last year was the Nissan LEAF polar bear ad. It was named the 2010 Commercial Of The Year by TopSpeed.
Nissan has a history of commercials that can help you think about a vehicle's features and its impacts in a new way. The below ad for example demonstrates the beauty of independent front end suspension.
“It is one aspect of the auto purchase decision that is an hindrance to the adoption of EVs (electric vehicles),” Driscoll said.
Scott of Plug In America disagrees.
“There are tens of millions of people for whom it’s not an issue at all. (Electric) carmakers will not run out of customers for years to come,” Scott said."

Batteries store charge by undergoing fairly complex chemical interactions, each time they charge and discharge there is slight degradation to the molecular structure of the battery. Lithium ion batteries operate by the inter-calation of lithium ions into the molecular structure of an electrode, which involves even more complex chemistry.
I couldn't find any lifetime numbers for the AESC batteries, but as of a few years ago, a typical Li-ion battery would exhibit serious degradation after a few thousand deep discharge / charge cycles.
Lithium battery chemistries are getting better all the time. But there is no question that fast charge is hard on batteries, you are putting huge amounts of current into the battery in a relative short time. Batteries have fairly high resistance, so there are thermal effects too. Unlike the Volt and the Tesla which liquid cool their batteries, the Leaf uses simple air cooling (a fan). So there is the possibility of elevated temperature during fast charge which can also reduce lifetime. (Be glad you are not fast charging your Leaf in August in Pheonix.)
If your driving patterns involve regular fast charge, then you will most likely reduce the lifetime of your batteries, the question is by how much. I'll keep looking for lifetime numbers for the AESC's cells and report back to you all if I find anything (some of you may be able to find such information too). As people have more experience with the Leaf, those numbers will become available.
As Mike Butts points out, it is ironic that the Tesla, which has a huge battery system, probably rarely fully discharges the pack and therefore has less need of fast charging, which means that it will probably have the fewest problems and longest battery lifetime. So the most expensive car will probably have the lowest battery replacement rate.
BTW, I have a friend who continues to "deep discharge" his cell phone and laptop to avoid "memory" effects. Li-ion batteries have very little memory effect (unlike Ni-Cad batteries), so my friend is basically just dramatically reducing the lifetime of these batteries for no good reason.
Proposal would charge drivers of electric cars | A “vehicle road usage charge” would stand in for the gas taxes other owners pay to help support the road network
1) The decreased gasoline demand will help keep prices in check. That saves money for gas drivers.
2) OR DEQ issues several Toxic Air advisories each year. Gas drivers seem to completely ignore these and drive anyway. Better air will save the state millions in medical costs. EVs (even coal powered EVs) produce far less pollution.
3) More Stable grid. Oregon has a large and growing wind power install base. The wind often blows harder at night. EVs will most often be charging over night. This stabilizes the grid and allows more renewables to be used in our state.
4) Gasoline is heavily subsidized in many ways. Avoiding its use means lower taxes for everyone.
5) EVs can be "fueled" in many ways. This creates a much more stable energy system than the dependency on a single source. Disruption in a single supply-chain will not result in price spikes since other sources can "pick up the slack".
6) We don't have to send the military to foreign countries to defend local energy systems. We can save billions in military spending and avoid the tragic loss of our sons and daughters. (Tillman Story)
