[ausev] onboard charger

[Sarah & Erik]

Hi Lisa,

On the other end of the spectrum are the transformer type battery
chargers. This one on ebay 280109862845 weighs about 35 lbs and isn't
small, but as I understand these transformer based chargers generally
are pretty good. They aren't typically adjustable as far as I know, so
I don't know if you can tweak setting for temperature, but they can
sometimes be found used at places that service golf carts. I know
there are versions that get up to 72V, but I'm not sure how much they
cost.

You could charge your pack with the one on Ebay at 36 V with three
additional switches and a small electronics project to make sure they
switch only when you want them to. Probably not a great idea, and if
you buy parts new it'll cost about the same as a proper charger, but
if you're wise in the art of scrounging and ok with the pitfalls it
can work.

The smallest Russco charger is in the $600 neighborhood as well.

I also have a charger that I'm not using, but it may not fit your
"good quality" requirment. It's a K&W BC-20 that I got with the parts
that are now in my car. I've hooked it up before and it definitely
works, but it isn't power factor corrected so it makes for a warm
cord. On the plus side it is light and small and would work well for
opportunity charging. I think they normally go for about 200 used. If
you're interested you're welcome to try it out.
