Nissan Leaf EV to Have Ultra-Cheap Battery Pack BY Ariel Schwartz Wed May 5, 2010
Over 8,200 people have made online reservations in the past month for the upcoming Nissan Leaf EV, and for good reason. The $33,000 vehicle, set to be released later this year, is the first affordable all-electric vehicle from a major auto manufacturer. It's an early adopter's dream. Now Nissan has revealed the secret behind the Leaf's reasonable price: an ultra-cheap battery pack.
While most lithium-ion batteries cost $1000 to $1,200 per kWh, the Leaf's 24 kWh battery pack costs just $9,000 to produce, or $375 per kWh, according to a report in the Times of London. In comparison, the Chevy Volt battery pack reportedly costs $600 per kWh, and even the U.S. Advanced Battery Consortium only has a goal of producing batteries at $400 per kWh by mid-decade.
So what gives? If the report is correct, Nissan could revolutionize the EV battery industry--assuming it will share its technology with other automakers. We still have our doubts, though, that this too-good-to-be-true pricing scheme is real. Nissan hasn't yet responded to our request for comment.
Thats right, YOU get to pay 7.8K for every smug liberal ahole that buys one of these.
When did we vote on that?
How much are we going to charge (pardon the pun) idiots who drive these for vehicle removal when their glorified Power Wheels dies in the middle of the road?
Good question.
Only 33K! Woo Woo!
Cheap SLA batteries?
Will they be like the battery packs for computer laptops, and have a couple of cells go bad making the entire pack useless?
A gallon of gasoline contains 40 kWh of energy. 24 kWh of gasoline costs less than two bucks.
$33K = affordable??
>> A gallon of gasoline contains 40 kWh of energy. 24 kWh of gasoline costs less than two bucks.
Yeah, but once you burn up the gas, it’s gone. You can charge the 24kWh battery pack up again and again and again! (With electricity from an oil or coal fired electric power plant. ;-) )
Gosh, an ultra-cheap battery that only costs $9,000? Wow!
And more KW-sucking greenies attached to the power grid with one hand, while they vote to close down coal, oil, and nuclear power plants with the other.
“A gallon of gasoline contains 40 kWh of energy.”
By my figures, this is wrong. The right answer is 28 kwh. Plus, the engine is only 40% efficient so that makes it effectively 11.176 kWh of useful energy.
thats what I said!
http://hypertextbook.com/facts/2003/ArthurGolnik.shtml. It’s in kilograms so you have to convert...
motor efficiencies are over 90%. Chargers in the high 90s.
LOL, just what I was thinking. Of course when I buy a car I take care of it and drive it until it just won’t run anymore or I give/sell it to a needy family member.
Still even a new car for me is a good used car. LOL
If I can’t pay cash I don’t buy it.

I suspect one of my barely-literate relatives will clean up
when it comes time to put one of these dead cars (and their battery) into
a land-fill.
(or make $$$ off the recycling scheme that surely must have already
been constructed by Obama and Co.).
...and then there’s the question where the energy to heat the darn thing in winter comes from. I figure you’d need a couple of kWs at least. So you’ll be driving slower or not go very far...
What a plan!! Only $11,000.
You wanna see traffic clogs?
Just wait ‘till the liberals start buying Leafmobiles and find they have to creep along at 20 mph on busy roads trying to squeeze a few more miles out of them just to get home to their federally-subsidized charging station without having to call for a tow truck.
LOL, great plan. I was only going to mention an auxilliary gasoline heater...looks like you’ve got the A/C problem covered as well!
I really like Nissan styling, but Volkwagen has a better idea: a four cylinder engine with a turbocharger! Wheeeeeeee! It’s economical until you need to accelerate and then it’s a kick in the seat.
Forget all those batteries and Rube Goldberg devices.

OK then, 97% charger efficiency, and 92% motor efficiency...
At 8 cents per KW-hr average (14.3 cents in New York state) the 40 KW-hr battery will take $3.58 cents to “fill up” and a high of $6.41 in NY.
Sounds like a fill up is more than half the price of old fashioned gasoline - after you have spent $33,000 on a puny little car...:^)
“Sounds like a fill up is more than half the price of old fashioned gasoline”
I wasn’t arguing that the electric car is viable, only that the numbers being used were wrong.
Indeed, the price of charging an electric car is bound to go up substantially once their in common use, because the tax man will find a way to extract the road tax...
Also, the electric car ends up polluting MORE, because much of the electricity will be generated by burning coal.
“its less than half that in useful energy, i.e. propulsion.”
Actually it’s worse than that... This efficiency conversion was based on both the gasoline engine and the electric motor(s) being the same size. They are not.
The sizing for electric motors in EV conversions is odd. A vehicle that used a 100HP engine would only take about a 20 HP electric motor to give similar performance. This is well established and has to do with the rating systems for gas versus electric motors among other things. Brake HP for gas engines and average for electric motors.
So we wouldn’t be comparing a 26 KW gas engine to a 26 kw electric motor. The equivalent gas engine would be maybe 120 KW.
In my opinion, Hybrids make a lot more sense than electrics though.
