54 Ultracapacitors in series with 12 12 volt batteries
12: The clever thing about using ucaps and lead acid batteries is that the lead acid batteries determine your range, while the ucaps determine the number of starts and stops you can make on the way to work. At that point, your best bet is to plan a route with the least amount of signals, or the least amount of signals which cannot be timed.
8.3: Capacitors in Series and in Parallel
When this series combination is connected to a battery with voltage V, each of the capacitors acquires an identical charge Q. To explain, first note that the charge on the plate connected to the positive terminal of the battery is (+Q) and the charge on the plate connected to the negative terminal is (-Q). Charges are then induced on the other plates so that the sum of the charges …
