Ideally I would like to use a 24V setup to do as you mentioned. The mazda I-eloop system uses a variable 12/25v alternator to regulate the charge build up in the capacitor bank. I know the logic behind this will be a challenge but I do think it is quite possible.

That being said from my understanding (which could be wrong) most newer cars come with variable alternators already. I could monitor this by using a multimeter to see what voltage is being produced during the recharge of the battery. I know it says on GM's website that the alternator produces 14v during the charge cycle and 12.5 in the normal running cycle but, today while driving I watched the voltage on my battery go up to 15.1v on the DIC. I wonder if the cruze alternator is already capable of 25v output.
