SAN FRANCISCO--A year from now, we'll be writing that same headline,
I guarantee you. Electric vehicles will still have lackluster sales,
some more car and battery companies will have gone out of business,
and perhaps there will be some scandalous news coming out of
Department of Energy technology grants.
That may seem a bold prediction given that there's still a huge
amount of hype flooding us week in and week out. Recently, for
A research company called Mintel made some noise this week, releasing
a report that indicated EV sales were up 73 percent
EVs could be tapped as backup power, under a pilot
program backed by the Department of Defense.
But reality is this: It's been two years since the Chevy Volt
rolled off the assembly line. GM's still selling Volts, but
slowly. Tesla is building a lot of Model S sedans, but buying an
expensive car is different than making one. Fisker's Karma is
struggling. Battery vendors are falling by the
roadside. That Mintel report seems sexy, but that 73-percent
increase is off a tiny base, and EV purchases are still just 3.3
percent of total vehicle sales. That's like celebrating RIM
Blackberry market share in the smart phone business today.
Stronger headwinds will buffet EVs in 2013. Why? Because of this
"We've gone from the innovators to the early adopters
who are not going to put up with a bunch of headaches. Now we're
in a market where people say, 'This has to work.'"
That's from Stan Sittser, transportation electrification project
manager for Portland General Electric. He was staffing the Portland
International Auto show recently, where he gave
an interview to a local newspaper. ,
The instructive part of his take is we're at a place in the story
where people expect the technology to work. Right now, it
doesn't, in the eyes of the average consumer. It doesn't work
technically, and it doesn't work economically.
The average consumer is reading blog posts and watching TV stories
about lithium ion batteries on fire in Boeing 787s and Chevy Volts.
They're watching YouTube clips of Fisker Karma
campfires in parking lots. Perhaps worse, they're
reading stories about Mitsubishi
recalling nearly 15,000 EVs because of brake problems
unique to electric motor-powered cars. But even the most forgiving
tech-savvy consumer has to stare at the price tag of one of these
vehicles and think there's a year or more of the kids'
private-college tuition in that list price.
I am not willing to pay a premium for an electric car. If an electric car has a range of 100 miles (I commute 90 miles per day) between charges in the dead of winter at 15 degrees F and costs no more than a ICE car, I will buy it. If not, forget it.
How about a source rather than an anecdotal, unsubstantiated "what-if"? You actually KNOW someone who "abused" the battery thusly, it died completely in these two years, and they refused to replace the battery due to the "abuse" because they could pull the record from the car.
Sounds highly unlikely for many reasons to me.
People talked about the original Prius batteries costing $10k to replace (oddly enough the same figure) back when they came out. Now, years later, the very first Prius' are beginning to need new batteries, and they can be replaced for between $1500 to $2500. Sounds like it's worth doing in most cases.
As far as "free or low cost service for 100,000 miles" , yeah... right... let me tally up what the service costs were for my Audi A6 Turbo for miles 60,000 to 100,000 (the first 60,000 were under warranty - needed to dump or extend the warranty before 60,000...) Those 40,000 miles were a lot more than $10,000...
"typically halving the range" - a bit of an exaggeration - I'd say more like "at the extreme tail, it MIGHT halve your range..." it's more like 2/3rds your range. Case in point, on a single charge, my Volt will break 50 miles all electric. In close to freezing, it might go down to 33-35 miles... I admit that I've never driven it in sub-freezing levels, but people were never meant to live in such places, much less drive! ;-)
It did occur to me that it could have been an urban legend.
I did a little bit more research, and there are reports that the console warning lights go crazy and inform that one really needs to add fuel before running out. Then it makes sure that the driver knows that there is no fuel. Once someone shuts it down without fuel and attempts to start it, it will give three chances to start with enough fuel before it shuts down and requires an engine code reset. There are reports that people might have been able to get up to two miles on the battery alone, although it progressively lowers speed (maxes at about 18 MPH).
So perhaps my original understanding was off. Turns out more detailed reports are that they are designed to keep the battery from depleting. However, running out of fuel is a bad idea. I don't know if Toyota will consider it abuse for warranty claims.
I absolutely agree, Kris! I'm only arguing EVs relative to ICEs. Moving a person or two at significant speed in a 1-1/2 ton box is energy intensive any way you cut it! Unfortunately, areas like mine have a lot of hills, are hostile to non-motor traffic, and have very weak public transport.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
