I'll admit it.

Any circuit which charges batteries scares me.  Perhaps I've put too 
much stock in those warnings on batteries and chargers, or seen the 
effect of an overcharged battery one too many times.   So, if a product 
design required charging batteries, I put it on the shelf for later, 
hoping that sometime I would conquer my fear.

Well, I guess that there is no better time than now to conquer my fears.

I have an application where I need to end up with a ~15 cell (18V) AA 
NiMH battery pack.  And I need to charge it from a automotive power 
source.   And preferably relatively quickly, like a 1 hour charger or 
similar.

Oh, and I'd prefer to keep melting, flame, and explosions to a minimum.  :-O

I've looked at a lot of charger circuits and I'm still scared.    What 
I'd really like is for someone (or someones) on the list to tell me how 
paranoid I am being (or not paranoid) and sort of give me some pointers 
of what to watch for. 
(Note I'm not suggesting LiIon... :)
