Seth,
Are you willing to add 1000 pounds to your vehicle? Even if the frame
and suspension can be modified to handle that, what are the losses from
carrying around all that extra weight. Alternatively, if you were to
put the spare battery in a trailer, what would your losses be from that,
including increased aero drag?
There have been a lot of past discussions on range extending. Trailers,
small onboard chargers, etc. In my opinion, they are rarely justified.

EVers,
With some talk about increasing battery size or adding another
compatible battery, I was thinking about this....I don't know
how complicated it is or isn't to have 2 batteries and load-balance,
and share the charger, etc.....that's fancy stuff....
but what about having a spare (charged) battery and a
transfer switch? Or, in its most primitive, a long cable
with an Anderson connector (great for POC).
It seems to me it would be simple to manage.
Drive to work, observe Oh No! only 10 miles of range left!
Press the A/B switch, Wow! 99% remaining!
In Phase 1, use the same onboard charger;
Charging would take twice as long...
When I get home, I plug in as is.
The next day, when my carpool drops me off,
I hit the A/B button to charge the other battery.
(Soon enough, I may have L2 charging at home,
so the change could be made in the morning
before riding in carpool)
In Phase 2, might have a second onboard charger
(might be able to get it from the SAME crashed LEAF :-).
If this worked, I could pull into a Nissan dealership
that isn't blocking the chargers....and use 2 chargers at once.
The question is, is there a good source of batteries
already removed? Or, is it "Easy enough" to
a) learn how to test the battery before taking apart
a strange dead car
b) get the tools needed - floor jack, dolly, custom screwdrivers, etc.
and then go to my local crashed car lot?
(I work not far from Hunts Point Auto Parts :-)
