Capacitor supply problem solving

[Enki]

So I'm very likely going to be running a capacitor bank in my project Falcon in place of any sort of battery, but I'm trying to work out how to make the most of the cap bank.

Many of you reading this may know that when using caps in series, the overall capacitance suffers greatly; for instance, a bank of 6 3,000 farad caps is reduced to ~500 farads capacity when strung together in series. In parallel, however, they hold the rated capacity; the problem with this is that the capacity listed is for a max of 2.7 volts.

I've been pondering the idea of making an all parallel bank to leverage closer to the full capacity of the caps, but the problem is building a setup to handle that kind of amperage.

Right now I'm looking at a requirement of 2400 watts (there's room to spare, of course) total consumption of the onboard systems; this translates to 200 amps at 12 volts, or ~172 amps at 14 volts (I'll probably run it at ~13.5 volts or so, but having 14 on tap could be beneficial).

The single biggest problem I can think of for a setup like this would be using a single charge and single discharge circuit; at 1 volts (at the capacitor), the amperage out would be around 2400 (which is where I'd stop discharging it, ideally).

Obviously, that's way, way too much and would provide a glorious spectacle as my car caught fire and/or exploded violently.

Spreading the load out on a per-capacitor basis, I'd only need 120 watts of discharge per cap with a total of 20 capacitors which is 120 amps at 1 volt; still high, but well within feasibility if the output circuit is mounted directly to the capacitor. This would provide an output between 12 volts, 10 amps and 14 volts, ~8.5 amps or so (per capacitor).

Now the only problem seems to be tying 20 some boost converters together so that one isn't drawn against more than the others, and this is where I'm in need of ideas.

While I won't be in a position to test any ideas full scale for quite some time, I may be able to test it small scale within the next month or two.

Thanks in advance for any input.
