I could not agree with you more and as you point out I have seen what your
talking about all the time. It is a challenge trying to explain an EV in
five or ten minutes. The vast majority of people are absolutely clueless
about electric vehicles. Many now think of Hybrids as an electric vehicle.
That battery powered electric vehicles only have the capability of an NEV or a
golf cart. It was easier before hybrids became common to explain EVs to
ICE drivers. I think it was better before because they did not feel they knew
anything. Now you have to retrain what they believe to be true is wrong. It
does not help when even the writers in ICE car magazines are mistaken as
well. Like plugging in a cell phone to charge in your Leaf is going to
affect your range. I could not believe that Car and Driver would print such lame
Your point that the public thinks EVs are worthless when the pack needs
replacement is valid. As all they have to compare to is an ICE vehicle value
after 10 or 15 years which is just a bit more then scrape metal. I see this
happening daily at mechanical shops. The customer is told the labor and
cost of a short block or used motor and it is beyond what they are willing to
invest back into the vehicle. For the price of the repair bill many times
they can buy a newer vehicle with about half the miles.
An ICE vehicle regardless of how well it is built has always been a throw
away car. You don't see many cars over 15 years old still on the road. I
think it is going to be a learning curve for ICE owners to understand the
changing economics of car maintenance with an EV. I understand your trying to
use the batteries as fuel to get to help them comprehend the overall cost
of an EV but I disagree this is the correct method. As Gary pointed out
batteries are far better then they were and improvements are coming fast.
In some respects I don't see the end of drivers looking for new or newer
vehicles. Being in the business I see it everyday how wear and tear takes it
toll over the years on vehicles used daily. Dents and dings from parking
lots start making the vehicle look beat up. Then locks start failing,
windows stop working, Door latches and wiper motors fail. I could go on and on
but the point is people get tired of what seems like a never ending list of
vehicle repairs. Most vehicles by this point are no longer looking good
inside or outside . When the motor or transmission fails that is many times the
There actually might come a day when you go to a new car dealership to buy
a glider. A glider is a vehicle that is bought without a motor or
transmission. Solectria did this building about 400 or 500 new electric vehicles
from GM. If you have an EV that the body and interior is worn out you just
then need another glider. You will use your old AC drive system because there
is nothing wrong with it and its still good for another 700,000 miles.
Gary is correct about the cycle life of A123 batteries. They are so well built
if you size a pack correctly for range it is unlikely your going to use up
their cycle life. The concern then is will you be able to put on enough
miles before calendar life becomes a major factor. I would not be surprised if
taken care of A123 calendar life could be 15 or 20 years.
So someday when you go to the dealership you might look at their motor and
controller options. You may also consider the latest technology in
batteries. Then you might decide to be thrifty and keep your current pack and
drive motor replacing only the body. The dealership would offer to do this or
you could go to an EV service shop.
It might seem like this is far in the future. However if you are older your
not going to surprised how quickly things can change. Twenty five years
ago hardly a home in the United States had a computer. Cell phones were new,
large, and very costly per minute and very few had one. The younger
generation having grown up with CDs, DVD's, cell phones and computers take them
for granted because they have always been there. I believe it will not be
long before EVs become as common as cell phones or computers are today.
Technology is rapidly changing our world we know which includes vehicles.
As much as some people scoff at EV's and would like to hang on to what is
commonly used for fuel today. It would not be in our best interest to delay
the replacement any longer then necessary. More then ever we need to get
away from our dependency of oil as quickly as possible.

I agree with all those things you say and to me it reinforces the need to
of the battery pack as fuel.? This could be a
good discussion for future meetings.? I would like to hear all opinions.
One of the things non-EV people seem to fear (based on what they say) is
they seem to assume that an EV is worthless
when the battery pack reaches 'end of life'.? They fear this 'big expense'
occur some time in the future.? And they equate it
to their experience of having a high mileage ICE car and the transmission
out.? Then their car becomes 'worthless' and they have
to decide whether to sell it for scrap, or dump in more money to fix the
transmission and perhaps risk something else
going out. I am sure many people reading this have faced this sometime in
But with my thinking, if the pack is thought of as fuel, then you are not
dumping money into this car to replace some broken part,
but simply pre-buying more fuel.? Evaluating the used EV is easier than
ICE because, yes, we expect millions of miles on an
electric motor and there are so few parts in the drive train that could
escape your attention.? So if the body is in good shape and the interior
ripped, one would be happy to buy a new pack, because that money is
fuel for the next
100,000 miles or more. If I were to buy a used EV, the best time to buy
right at the end of life of the pack, or
right after the pack was swapped with a new one.? In both cases, you can
accurately value this purchase.? It would be harder to
value a used EV with 50,000 miles on the pack, because you may have no
the previous owner drove and treated the pack
(i.e. wasted fuel).
The other reason I think of the pack as fuel is because then the current
an EV actually becomes competitive with an ICE
car without any incentives.? A $25,000 ICE can be compared with a $35,000
because of the prepaid fuel concept.? At the time
of purchase, most people never consider that they are going to spend
more on gasoline over the next 100,000 miles.
Perhaps we should not get hung up on the meaning of fuel, my purpose is
to create an analogy that makes it easier to have a common ground to
the economics between an ICE or EV purchase.? Once we get someone
true costs, then we can talk about other interesting topics like how much
electricity was consumed fueling their ICE car and other
