Hybrids usually use NiMH (nickel metal hydride) batteries.
Generally, 500 to 1,000 full discharge/charge cycles is about the
upper limit for the life of such a battery.
But hybrid cars don't discharge their batteries very deeply at
all. So the above figures become somewhat meaningless. In that
situation, what's important is the cumulative total energy taken
from / returned to the battery. And just age and temperature
We'll really have to wait and see as a history develops for this
battery chemistry in this application.
I'd expect so - shorter life that those used in hybrids.
I haven't researched the battery types used in full-electric
cars, but I'd expect them to be more exotic chemistries, selected
with very strong emphasis on the energy-to-weight ratio.
I'm a little skeptical. Just because they warrant
the batteries for 8 years/100K miles doesn't mean
they'll last that long. After 100K, which could
well happen well before 8 years, you get stuck
with cost of battery replacement which I
understand is around $6000. Assuming the best case
scenario of the batteries lasting 100K it still
adds $0.06/mile to your "fuel" cost, possibly
more. The difference in fuel cost/mile from my
motorcycle at 45mpg and my 300D at 27mpg is only
$0.02/mile. SO what you wind up with after the
warranty period is a worthless pile of junk that
will likely have a bigger negative environmental
impact from disposing the batteries and cluttering
the junkyards than all the feelgood it generated.
Yes, but while drving it around town, the greenies get to feel like
they are so much better than the rest of us and are doing something
that will save the environment. That alone is priceless.
How about the news stories on the all electric cars or plug-in
hybrids? They go on and on about how the cars emit zero or low
emissions, but NEVER mention the electricity has to come from
somewhere. If ever pushed on it, the greenies come up with the usual
story, which is the electricity will come from wind and solar....
Yet when it comes time to actually implement that, who's blocking it?
The greenies again, who don't want windmills offshore, in the desert,
etc because that too is harmful to the environment.
