Re: [EVDL] Daily driver vs. hobby: EV reliability issues & OEM massproduction

I'm going to chime in here, since this is something that I've
been thinking about the last few years. I've been driving my own
EV for the last thirteen years.

Yes, I've come to much the same conclusion. My bunny has been
much more work than I had planned on. But I've decided that
pretty much any custom vehicle is not going to have that OEM
Honda/Toyota reliability. Conversion EVs are a special difficult
case. Production is very low count. I would say much lower than
most stuff for custom cars. Headers and hot variable cams plus
the latest electronic goodies for modifying that ECU in your gas
street rod are made by the thousands. Compare that to the
tens-ies and hundreds count that might occur for conversion EVs.
All that iterating for gas cars moves them up the learning curve
and amortizes the cost. And OEMs run that count up into the
millions. Big market. You can go to your local Kragens and most
likely get part XYZ, and if they don't have it on the shelf,
they've got a sheaf of catalogs about a foot wide where they can
look. The EV conversion parts market can just about be counted
on the fingers of one hand, and any one of those may go out of
business before you call the next time. I admire the staying
ability of our EV parts suppliers given the economics, and I keep
my fingers crossed that we continue to have good people to go to
in the future. EV conversions are far out on the fringe of the
custom car world.

Have we had the OEM experience in the EV world, vehicles that the
average EV driver could get their hands on? No, I would say not.
I don't think the GM EV1, the Toyota RAV4-EV, Honda EV-Plus, and
blah-blah-blah hundreds of vehicles that went down in the last
10-15 years really counts. All this pretty much amounted to a
publicity stunt by the OEMs and to fill CA CARB requirements -
the whole affair makes me retch. You had to be well-connected,
rich and in the right place at the right time to have one of
these vehicles as your daily driver. And by rich, I mean here in
CA if you live in an apt and can't make those mega-buck housing
prices to have a garage to stow your EV in, you're out - no way
could I have a dedicated power unit hanging on the wall
downstairs in my carport, and the OEMs wouldn't even look at my
apt scene.

Given all that, I feel I'm doing the best I can for whatever
reason(s) I am doing it. Sure, I'd like to have an OEM electric
like the GM EV1 NiMH. I might just about kill for one too, but
it ain't gonna happen. I drive my conversion, as I have for the
last 13 years, and make it the best experience I know how. I
expect it to cost me a lot of time and effort in the future. It
needs its space, and I need mine. But it works.

That's how it came out this time when I wrote this. Somedays are
a little different...

> Boy, this really hits the nail of what I have been thinking
about the last few weeks on the head. I ask myself 'would I do a
fiero again?' And the answer is maybe, but the reality is that
now I have a pretty decent one that I've invested a lot in, and
It's gonna be around for a while now.

tire rack get here...
