No.
The only way to not charge the battery is to remove it or hack apart your laptop to not sense the battery was there when a flip was switched or something, but that would require a lot of work, voiding warranties, and soldering. THe short answer is NO.
I don't know why you are so against what I reccommended in the previous thread you started. Hopefully you have read by now that constant charge and discharge is good for a battery. And unless your car is on 24/7, I don't know what the problem would be.
