Any one notice durability from a manufacturer for the most part usually
seems to be a problem after the warranty coverage is expired?
Gary I see your concern about all the moving parts in the Volt. Hard to say
for sure how all that is going to hold up but the batteries should do very
If you read the information posted on the Volt link. Most of the
limitations are do to the smaller capacity of the pack and the restriction of not
allowing the pack to be deeply discharge. Its obvious GM is trying to make
sure the pack last to the end of the warranty by providing maximum pack
Its one of the reasons I like a pack sized more along the lines of the
Leaf. There are a lot of advantages to having an oversized pack. With the
current battery chemistries the down side is added cost, weight and space. The
up side is high demand loads are not as much of a factor so having the ICE
kick on would not be needed. Also your all electric range such as in a
Hybrid will be greatly increased. What I like is a larger pack will last far
longer time then a smaller pack under the same loads. With a larger pack the
all electric range is increased enough that for most people the need of an
ICE is just about eliminated.
As an example of a Leaf driver who drives about thirty to forty miles a
day. Does not use fast charging or tops off above a 90% state of charge is
going to get maximum pack life. If you drive conservative as well, it is
possible you will have two or three times the pack life stated by Nissan. A
driver who drives with their foot to the floor and deeply discharges most
likely will still make the warranty. How much longer though depends on your
overall use and charging.
Battery reliability I believe will be far better than an internal
combustion engine drivetrain overall. If you drive an ICE hard you will wear out
the drivetrain. In an EV the most likely maintenance will be replacing the
batteries. Which is not as difficult or as messy as a major ICE overhaul of
the motor or transmission. Also by the time replacements modules are going
to needed the cost will be far less then today. This is if you drive like
any other ICE driver on the road.

A basic explanation of the Volt's five different operating modes.
Could durability of all these components be a problem as the wear and
tear of 1000s of miles driven comes into play?
