A very large trailer to put all those supercaps on.i want to assemble a 48v supercapacitor battery for using in electric bike. what are the other things required for assembling in addition to super capacitors?
How did you get 100, 000 farads? Thanks.A very large trailer to put all those supercaps on.
Let's just do a simple computation to see what capacitance would be needed to store the amount of energy that is stored in a single D-cell alkaline battery. The amp-hour rating of the D-cell is approximately 17 A·h, which works out to about 75 kJ (since the terminal voltage decreases as the battery is drained).

To match that at the nominal 1.5 V terminal voltage a capacitor would have to be 100,000 farads. Now consider how far you could possibly expect to get on an electric bike powered by a single alkaline D-cell.
You're correct. I did the math in my head and although I checked the units mentally on dividing by (1.5 V)², I only divided by 1.5 once (I was probably too impressed with that coming out to such a nice, round figure). The point is still quite valid though. Thanks for checking the math and pointing out the error.How did you get 100, 000 farads? Thanks.
E = 1/2* CV^2 = 75kJ where V = 1.5V. I got C about 66,666 farads.
