[ausev] Iota converter

[The Mullins]

One reason I'm using a small battery and a converter is flexibility. I would
have a hard time finding room for a full-sized battery, yet the motorcycle
battery and converter together occupy about the same space as a large
battery but allow me to split them up and locate them in two small spaces
rather than one larger space. If the small battery is sealed then there are
even more options and the converter can also be mounted in various ways.

I have a Geo Tracker with 12V battery and no DC-DC.  It works OK.  I use a
standard automotive  battery and it lasts at least two full charge-discharge
cycles of the main pack before I have to recharge it.  I've been caught once
with dead battery and it was very irritating.

In the future I'll probably get a small DC-DC to supplement the aux battery.
I don't necessarily feel the need to size it to keep up with my average
load.  I would call this a 'depletion' mode setup (if I may steal a term
from the semiconductor industry) where the additional charge extends the
effective range of the 12V battery just long enough to get the vehicle to
work, charge it up while it sits in the parking lot, and then charge it up
overnight while the main pack charges, etc..  another perspective.


Then again, I might get a solar panel to do the same thing...

wouldn't be big enough for additial loads. I'm thinking that I might want to
add a heater(with fan) in the future. Maybe the CanEV type. Back the drawing
board!


The CanadaEV heaters use high voltage... or at least mine uses the
full 144V of the traction battery pack.  That is much more useful than
a 12V electric heater.
