Well, no, but if the EV1 had had the time, perhaps some very expensive
parts would have begun to fail. The EV1 was chock full of expensive
parts.

And sometimes the automakers actually do start using parts that don't
need to be replaced as often. Such as LED tail lights.

Or, a definite reason to get a bunch of them on the roads and keep them
running until the battery pack needs to be replaced

Others (such as "EV Basher" Mark Brueggeman) have pointed out that EV
conversions still have maintenance costs. He notes that the increased
load of batteries shortens the life of the chassis and brakes. Acid
from lead-acid batteries corrodes things. There's (usually) still a
transmission, and it's subjected to loads it wasn't designed for. Etc,
etc.

Anyway, at the risk of veering off-topic, it looks to me like GM wanted
the EV1 to be full of expensive, proprietary parts, so the buyers would
be locked into using GM for service and support. I think they expected
to make a lot of money on the EV1.

I agree with you - EVs have fewer systems, and they generally require
less maintenance than the corresponding system in an ICE. But it would
be a mistake to ignore the costs that definitely do exist, or to claim
that the long-term costs are less than that associated with a modern
ICE in advance of actually running the numbers.

Has someone run the numbers? Say, compared a converted late-model
Honda to the identical car in ICE trim, over a span of a few years (or
miles)? If you run a cost-per-mile comparison, the EV wouldn't look so
good, I bet. They see so few miles by comparison to their ICE
brethren.

How exactly would you go about making a fair comparison?

Re: [EVDL] GM EV1

You're absolutely right that we shouldn't underestimate the costs
associated with running an EV.

That being said, I think you're underestimating the costs saved vs. an
ICE car

You're not ever having to replace: Exhaust system parts or engine
parts. No oil changes meaning no motor oil, nor oil filter changes. No
fuel issues. No fuel system replacements or filter changes. Brakes are
only an issue on cars without regenerative braking and it's likely
that full on production EVs will all have regen. And you won't have to
have bi annual tune ups.

This all represents a HUGE amount of the burden of owning an ICE. I
completely agree.. in a standard conversion you will be replacing
brakes and shock components more often.. HOW much more often depends
on who designed the thing. If you use robust components it should be
at a mild premium over ICE cars/trucks.

Controllers are the next big thing. They usually come with warranties
and can just be swapped out whole hog. Unless you've wedged it into a
wheel well, they are usually easily removed and replaced.

Motors are the next thing. They almost never go bad, ever (except at
the races . If one did, though, it could be pretty pricey. About as
much as a small ICE, new.

Battery replacement is the last big thing. This is a mixed bag, but it
usually goes cheaper = more often. And hopefully the conversion was
designed so you don't have to tear out too much to do it

Transmission! Yeah, this is my sticking point too. That will have the
same maint woes of any transmission. EVs are normally manual though,
and they tend to be pretty tough.. I have over 100,000 miles on my
Golf VW trannie and never had an issue with it.

Bits and bobs can go too, but again.. contactors can be oversized
enough so they will almost never fail, and so on. High power
electrical components have become extremely reliable and since there
are almost no moving parts, that makes everything even more robust.

I don't think you -can- make a true comparison, though, until there is
an actual playing field on which to do it, with a few years of
maintenance reports from EVs to show cost differentials.
