With the risk of sticking my foot in my mouth, as I have not built my
own EV, I'd like to make a few suggestions.
One, start with goals. How far do you want to be able to drive? What
kind of acceleration? How steep a hill? Do you need to tow anything?
Or carry a heavy load uphill?
And lesser things: do you need a lot of cabin heat? defrost?
Then do the math. There are various acceleration and load tools on the
Internet that can help you determine how much torque or KW you need to
meet your goals. Knowing how many KW your goals require, you can
multiply that by range to size your battery. And so on.
With all these numbers you can start looking at components. The
priciest ones are going to be the battery, the motor, and the controller
or inverter. If these are way out of price range or, for example, you
the battery will be too heavy for the truck, you may need to compromise
on some of your goals. You might decide to keep the clutch and gear box
rather than replace them with a single gear reduction. A little less
efficient but potentially a lot cheaper.
Hopefully, you'll be able to iterate through this process, reducing or
compromising your goals, until you reach something that is cost
justifiable. Otherwise you would just go buy the Tesla :) I can't
begin to enumerate all the small components you will need - from charge
port to an electric pump for the brakes to dashboard meters. Books, the
EV album, and other people will be your resources.
Good luck !

Hi Bob,
Build you own electric vehicle by Bob Brant. It is available at Amazon
and
on Kindle. It gives excellent pointers, even if some of the info is
dated.
The beauty of electric vehicles is that typically, each of the basic
components can be changed or updated with little regard to the others
(motor, controller, batteries). Yes, it is wise to do your best to
match
these up for maximum benefit, but many of us have gone against that
wisdom
and done surprisingly well. It is a fledgling enterprise after all and
it
seems that no one knows all.

I plan to buy a new ev when the range is high enough, and they don't
cost
as much as a Tesla S. In the near term I am considering the
conversion of
my 1951 Chevy pickup to ev, probably with it's own solar panels. I
could
also charge it from the solar panels that power my house. Can anyone
recommend fairly up-to-date books that are specific to converting an
ICE
vehicle to EV?
